Definitions
- the present invention relates to low profile finned heat exchangers used for cooling fluid.
- Low profile heat exchangers are typically used in applications where the height clearance for a heat exchanger is quite low, for example, slush box coolers in snow mobiles, and under-body mounted fuel coolers in automotive applications.
- One style of known low profile heat exchangers include a louvred plate that is exposed to air flow, snow and general debris, with a serpentine tube affixed to and passing back and forth across the plate. The fluid to be cooled passes through the serpentine tube.
- Another style of known low profile heat exchanger includes fins running transverse to and integrally extruded with top and bottom walls that are connected along opposite side edges to define a cavity that is welded shut at opposite ends after extrusion to provide a fluid cooling container.
- Known low profile heat exchangers can be heavy and can be relatively expensive to manufacture. Thus, there is a need for a low profile heat exchanger that is relatively light weight and relatively cost efficient to manufacture. Also desired is a low profile heat exchanger that has an improved fluid temperature drop for its relative size.
- a low profile heat exchanger that includes a fin plate having opposite facing first and second sides and including a plurality of spaced apart elongate fins that extend outward from the first side and define a plurality of elongate passages that are open facing on the second side, and a low profile container having spaced apart cover and shim plates sealably joined about peripheral edges thereof and defining a fluid conducting chamber, the container having an inlet opening and an outlet opening in communication with the fluid conducting chamber.
- the first side of the fin plate is mounted to the shim plate to permit thermal transfer therebetween and the second side of the fin plate is exposed.
- a low profile heat exchanger that includes an extruded fin plate having a planar support wall with opposite facing first and second sides and including a plurality of spaced apart elongate fins that extend outward from the second side and define a plurality of passages that are open facing away from the second side, and a separately formed low profile cover plate having a substantially planar central portion that is spaced apart from the first side of the support wall, the cover plate and support wall being joined about peripheral edges thereof and defining a fluid conducting chamber therebetween with an inlet opening and an outlet opening in communication with the fluid conducting chamber to permit a fluid to pass into, through, and out of the fluid conducting chamber.

- the heat exchanger 10 includes a bottom fin plate 12 , a shim plate 14 , a turbulizer plate 16 , and a cover plate 18 .
- the plates are shown vertically arranged in FIG. 1 , but this is for the purposes of explanation only.
- the heat exchanger can have any orientation desired.
- the cover plate 18 together with the shim plate 14 define a flattened, low profile container having an internal fluid conducting chamber 24 .
- the cover plate 18 includes a central planar portion 20 that is generally rectangular in the illustrated embodiment.
- a sidewall flange 22 is provided around all four peripheral edges of the central planar portion 20 .
- the sidewall flange 22 extends towards the shim plate 14 providing a continuous sidewall about the fluid conducting chamber 24 .that is defined between the cover plate 18 and the shim plate 14 .
- Outwardly extending connecting flanges 26 are preferably provided along the bottom edges of at least one pair of opposing wall portions of the sidewall flange 22 .
- Each connecting flange 26 has a planar surface 27 that abuts against and is secured to the shim plate 14 .
- a pair of fluid flow openings 28 and 30 are provided through the central planar portion 20 in communication with the fluid conducting chamber 24 .
- cylindrical fittings 32 , 34 having flow passages therethrough are provided for openings 28 , 30 .
- the fittings 32 , 34 may have annular flanges 36 sealably connecting the fittings to the cover plate 18 .
- cover plate 18 is of unitary construction and made of roll formed or stamped aluminum alloy that is braze clad.
- the shim plate 14 is simply a flat plate having a first planar side that faces an inner side of the central planar portion 20 of the cover plate 18 , and an opposite planar side 37 that faces and is connected to the fin plate 12 .
- the shim plate 14 is substantially rectangular in the illustrated embodiment, having a footprint that is approximately the same as the footprint of the cover plate 18 .
- Shim plate 14 is, in a preferred embodiment, made from a braze clad aluminum or aluminum alloy sheet.
- the fin plate 12 is, in one preferred embodiment, a unitary structure formed from extruded aluminum or aluminum alloy.
- the fin plate 12 includes a flat support wall 38 having a first planar side 40 facing and secured to the shim plate 14 , and an opposite facing side 42 on which is provided a plurality of elongate, parallel fins 44 .
- Mounting flanges 46 having securing openings 48 therethrough may be provided along opposite side edges of the support wall 38 to allow the heat exchanger to be mounted to a surface.
- the fins 44 each run substantially from a first end to a second end of the support wall 38 , and define a plurality of elongate passages 50 therebetween.
- the side of the fin plate 12 facing away from the shim plate 14 is open such that alternating fins 44 and passages 50 are exposed so that in use, air can flow through the passages 50 and over fins 44 .
- other substances such as water and snow and other debris may be thrown against the exposed fins and passages.
- the fins 44 are straight fins, that each extend a uniform distance at a perpendicular angle from the outer planar side 42 of the fin support wall 38 , and which run from one end to an opposite end of the heat exchanger.
- the turbulizer plate 16 is located in the fluid conducting chamber 24 to augment fluid flow therein and thereby increase the efficiency of heat removal from the fluid.
- the turbulizer plate 16 is formed of expanded metal, namely aluminum, either by roll forming or a stamping operation. Staggered or offset transverse rows of convolutions 64 are provided on turbulizer plate 16 .
- the convolutions have flat bottoms and tops 66 to provide good bonds with cover plate 18 and shim plate 14 , although they could have round tops, or be in a sine wave configuration, if desired.
- transverse crimped portions 68 and 69 Part of one of the transverse rows of convolutions 64 is compressed or roll formed or crimped together to form transverse crimped portions 68 and 69 (crimped, as used herein, is intended to include crimping, stamping, roll forming or any other method of closing up the convolutions in the turbulizer plate 16 ).
- Crimped portions 68 , 69 form a barrier 62 to reduce short-circuit flow inside the fluid conducting chamber 24 .
- the barrier 62 is represented using phantom lines in FIG. 7 , and runs between the flow openings 28 and 30 so that fluid entering at one opening 28 or 30 simply cannot take a straight path through the convolutions 64 in the fluid chamber 24 and exit at the other flow opening 30 or 28 , but rather must take a more circuitous route.
- the barrier 62 extends from close to the common end 60 to a point 72 that is set off from the opposite end 58 of the heat exchanger 10 such that a substantial portion of the fluid flowing into the chamber 24 from opening 28 must flow in a U-shaped flow path around point 72 , as indicated by arrow 74 , prior to exiting the chamber 24 through opening 30 (in the case where opening 28 is the inlet and opening 30 is the outlet for chamber 24 ).
- the cover plate 18 and the shim plate 14 are formed from braze clad aluminum, and the heat exchanger 10 is constructed by assembling the parts in the order shown in FIG.
- soldering could, in some applications, be used in place of brazing from connecting the components together.
- Other metallic materials for example steel, and non-metallic polymer materials could be used to form some or all of the components of the heat exchanger for some embodiments.
- Polymer components could be thermally bonded together, ultrasonically bonded, or bonded using adhesive or other means.
- the heat exchanger 10 can conveniently be used as a low-profile device for cooling a fluid that passes through the fluid flow container defined by the cover plate 18 and shim plate 14 , with heat from fluid being conducted away from the fluid to exposed fins 44 , which in turn are cooled by air passing there through. In some applications, the cooling of exposed fins 44 is assisted by other substances such as snow and water that gets thrown against the exposed fins 44 .
- the heat exchanger 10 can be used, for example, as an engine coolant cooler in a snowmobile, or as an underbody mounted fuel cooler in an automotive application, although these examples are not exhaustive.
- the heat exchanger 10 can be manufactured in different sizes relatively easily by extruding longer fin plates 12 and roll forming correspondingly longer shim and cover plates 14 , 18 .
- cover plate 18 has been described above as having an integrally formed sidewall flange 22 , in some embodiments, separate sidewalls may be used.
- shim plate 14 could be omitted, and in its place the upper side of the support wall 38 used as the bottom wall for the fluid conducting chamber 24 .
- the heat exchanger 10 has been illustrated as being rectangular, it could also have different shapes—for example it could have a circular disc-like configuration in some applications.
- FIGS. 8 and 9 show a further shim plate 78 that could be used in place of shim plate 14 in the heat exchanger 10 .
- the shim plate 78 has a central elongate baffle wall 80 extending transversely upward therefrom to the cover plate 18 (not shown in FIG. 8 ).
- the baffle wall 80 is positioned between locations at which the flow openings 28 and 30 are provided through the cover plate 18 (such locations being illustrated by the phantom lines 28 ′ and 30 ′ in FIG. 8 ) such that baffle wall causes the fluid in chamber 24 to follow an indirect U-shaped flow path as indicated by flow arrow 82 .
- the baffle 80 is preferably formed from a portion of the shim plate 78 that has been stamped out along three side edges and then pivoted, upwards about a fourth side edge that remains connected to the rest of the shim plate 78 , leaving a rectangular opening 84 through the shim plate 78 that is sealably blocked by the support wall 38 .
- Separate turbulizer plates can be located on opposite sides of the baffle wall 80 .
- FIGS. 10 and 11 show a skeletal baffle plate 86 that can be used in place turbulizer plate 16 between shim plate 15 and cover plate 18 in a further alternative embodiment of heat exchanger 10 .
- the positions of flow openings 28 and 30 relative to the skeletal baffle plate 86 are illustrated by phantom lines 28 ′ and 30 ′ in FIG. 10 .
- the skeletal baffle plate 86 includes an outer rectangular frame 88 that is dimensioned to snugly fit within the sidewall flange 22 of the cover plate 18 .
- the skeletal baffle plate 86 has a height H (see FIG. 11 ) that conforms to the height of the fluid chamber 24 , and includes alternating substantially parallel baffle walls 90 , 92 .
- Baffle walls 90 extend from a first end wall 94 near where the flow openings 28 , 30 are positioned, to close to an opposite end wall 96 .

- baffle walls such as those provided by skeletal baffle plate 86 could instead be provided by embossed ribs formed on the shim plate 14 or on the cover plate 18 or on both, and in many applications embossed ribs on the cover and/or shim plate will be preferred to a separate baffle plate as it reduces the number of components that need to be assembled.
- embossed cover plate configurations suitable for use with the heat exchanger 10 are presented below.

- the U-shaped fins 138 and connecting walls 144 collectively form a square-corner corrugation.
- the fins 138 are formed to have a uniform size, but with soft undulating curves along their length to assist in interrupting the boundary layer of any air flowing therethrough.
- the fins 138 are preferably light-weight and roll-formed or stamped from aluminum or aluminum alloy.
- the alternating open-faced and closed-face passages 140 , 142 each have substantially the same cross-sectional area, however different relative areas could be used depending on the application. Also, different fin profiles could also be used, for example, V-shaped fins could be used.

Description
- This application claims priority to Canadian Patent Application No. 2,372,399, filed Feb. 19, 2002.
- The present invention relates to low profile finned heat exchangers used for cooling fluid.
- Low profile heat exchangers are typically used in applications where the height clearance for a heat exchanger is quite low, for example, slush box coolers in snow mobiles, and under-body mounted fuel coolers in automotive applications. One style of known low profile heat exchangers include a louvred plate that is exposed to air flow, snow and general debris, with a serpentine tube affixed to and passing back and forth across the plate. The fluid to be cooled passes through the serpentine tube. Another style of known low profile heat exchanger includes fins running transverse to and integrally extruded with top and bottom walls that are connected along opposite side edges to define a cavity that is welded shut at opposite ends after extrusion to provide a fluid cooling container.
- Known low profile heat exchangers can be heavy and can be relatively expensive to manufacture. Thus, there is a need for a low profile heat exchanger that is relatively light weight and relatively cost efficient to manufacture. Also desired is a low profile heat exchanger that has an improved fluid temperature drop for its relative size.
- According to the present invention there is provided a low profile heat exchanger that includes a fin plate having opposite facing first and second sides and including a plurality of spaced apart elongate fins that extend outward from the first side and define a plurality of elongate passages that are open facing on the second side, and a low profile container having spaced apart cover and shim plates sealably joined about peripheral edges thereof and defining a fluid conducting chamber, the container having an inlet opening and an outlet opening in communication with the fluid conducting chamber. The first side of the fin plate is mounted to the shim plate to permit thermal transfer therebetween and the second side of the fin plate is exposed.
- According to another aspect of the present invention, there is provided a low profile heat exchanger that includes an extruded fin plate having a planar support wall with opposite facing first and second sides and including a plurality of spaced apart elongate fins that extend outward from the second side and define a plurality of passages that are open facing away from the second side, and a separately formed low profile cover plate having a substantially planar central portion that is spaced apart from the first side of the support wall, the cover plate and support wall being joined about peripheral edges thereof and defining a fluid conducting chamber therebetween with an inlet opening and an outlet opening in communication with the fluid conducting chamber to permit a fluid to pass into, through, and out of the fluid conducting chamber.

FIG. 1 , there is shown an exploded view of a heat exchanger, indicated generally byreference numeral 10, according a preferred embodiment of the invention. Theheat exchanger 10 includes abottom fin plate 12, ashim plate 14, aturbulizer plate 16, and acover plate 18. The plates are shown vertically arranged inFIG. 1 , but this is for the purposes of explanation only. The heat exchanger can have any orientation desired. - Referring to
FIGS. 1 and 2 , thecover plate 18 together with theshim plate 14 define a flattened, low profile container having an internalfluid conducting chamber 24. Thecover plate 18 includes a centralplanar portion 20 that is generally rectangular in the illustrated embodiment. Asidewall flange 22 is provided around all four peripheral edges of thecentral planar portion 20. Thesidewall flange 22 extends towards theshim plate 14 providing a continuous sidewall about the fluid conducting chamber 24.that is defined between thecover plate 18 and theshim plate 14. Outwardly extending connectingflanges 26 are preferably provided along the bottom edges of at least one pair of opposing wall portions of thesidewall flange 22. Each connectingflange 26 has aplanar surface 27 that abuts against and is secured to theshim plate 14. - A pair of
fluid flow openings planar portion 20 in communication with thefluid conducting chamber 24. In one embodiment,cylindrical fittings openings fittings annular flanges 36 sealably connecting the fittings to thecover plate 18. - In a preferred embodiment the
cover plate 18 is of unitary construction and made of roll formed or stamped aluminum alloy that is braze clad. - The
shim plate 14 is simply a flat plate having a first planar side that faces an inner side of the centralplanar portion 20 of thecover plate 18, and an oppositeplanar side 37 that faces and is connected to thefin plate 12. Theshim plate 14 is substantially rectangular in the illustrated embodiment, having a footprint that is approximately the same as the footprint of thecover plate 18.Shim plate 14 is, in a preferred embodiment, made from a braze clad aluminum or aluminum alloy sheet. - The
fin plate 12 is, in one preferred embodiment, a unitary structure formed from extruded aluminum or aluminum alloy. Thefin plate 12 includes aflat support wall 38 having a firstplanar side 40 facing and secured to theshim plate 14, and an opposite facingside 42 on which is provided a plurality of elongate,parallel fins 44.Mounting flanges 46 having securingopenings 48 therethrough may be provided along opposite side edges of thesupport wall 38 to allow the heat exchanger to be mounted to a surface. - With reference to
FIGS. 2 and 3 , thefins 44 each run substantially from a first end to a second end of thesupport wall 38, and define a plurality ofelongate passages 50 therebetween. The side of thefin plate 12 facing away from theshim plate 14 is open such that alternatingfins 44 andpassages 50 are exposed so that in use, air can flow through thepassages 50 and overfins 44. In some applications, other substances such as water and snow and other debris may be thrown against the exposed fins and passages. In the heat exchanger shown inFIGS. 1-3 , thefins 44 are straight fins, that each extend a uniform distance at a perpendicular angle from the outerplanar side 42 of thefin support wall 38, and which run from one end to an opposite end of the heat exchanger. - The
turbulizer plate 16 is located in thefluid conducting chamber 24 to augment fluid flow therein and thereby increase the efficiency of heat removal from the fluid. With reference toFIGS. 4,5 , 6 and 7, in a preferred embodiment, theturbulizer plate 16 is formed of expanded metal, namely aluminum, either by roll forming or a stamping operation. Staggered or offset transverse rows ofconvolutions 64 are provided onturbulizer plate 16. The convolutions have flat bottoms and tops 66 to provide good bonds withcover plate 18 andshim plate 14, although they could have round tops, or be in a sine wave configuration, if desired. Part of one of the transverse rows ofconvolutions 64 is compressed or roll formed or crimped together to form transversecrimped portions 68 and 69 (crimped, as used herein, is intended to include crimping, stamping, roll forming or any other method of closing up the convolutions in the turbulizer plate 16).Crimped portions barrier 62 to reduce short-circuit flow inside thefluid conducting chamber 24. Thebarrier 62 is represented using phantom lines inFIG. 7 , and runs between theflow openings opening convolutions 64 in thefluid chamber 24 and exit at the other flow opening 30 or 28, but rather must take a more circuitous route. In the illustrated embodiment in which the twoflow openings common end 60, thebarrier 62 extends from close to thecommon end 60 to a point 72 that is set off from theopposite end 58 of theheat exchanger 10 such that a substantial portion of the fluid flowing into thechamber 24 from opening 28 must flow in a U-shaped flow path around point 72, as indicated byarrow 74, prior to exiting thechamber 24 through opening 30 (in the case whereopening 28 is the inlet andopening 30 is the outlet for chamber 24). In a preferred embodiment, thecover plate 18 and theshim plate 14 are formed from braze clad aluminum, and theheat exchanger 10 is constructed by assembling the parts in the order shown inFIG. 1 , clamping the parts together and applying heat to the assembled components in a brazing oven, thereby sealably brazing the cover plateside wall flange 22 about its lower end to theshim plate 14 with theturbulizer plate 16 sandwiched between thecover plate 18 andshim plate 14, and brazing theshim plate 14 to thesupport wall 38 of thefin plate 12. Soldering could, in some applications, be used in place of brazing from connecting the components together. Other metallic materials, for example steel, and non-metallic polymer materials could be used to form some or all of the components of the heat exchanger for some embodiments. Polymer components could be thermally bonded together, ultrasonically bonded, or bonded using adhesive or other means. - The
heat exchanger 10 can conveniently be used as a low-profile device for cooling a fluid that passes through the fluid flow container defined by thecover plate 18 andshim plate 14, with heat from fluid being conducted away from the fluid to exposedfins 44, which in turn are cooled by air passing there through. In some applications, the cooling of exposedfins 44 is assisted by other substances such as snow and water that gets thrown against the exposedfins 44. Theheat exchanger 10 can be used, for example, as an engine coolant cooler in a snowmobile, or as an underbody mounted fuel cooler in an automotive application, although these examples are not exhaustive. - The
heat exchanger 10 can be manufactured in different sizes relatively easily by extrudinglonger fin plates 12 and roll forming correspondingly longer shim and coverplates cover plate 18 has been described above as having an integrally formedsidewall flange 22, in some embodiments, separate sidewalls may be used. Furthermore, in some embodiments,shim plate 14 could be omitted, and in its place the upper side of thesupport wall 38 used as the bottom wall for thefluid conducting chamber 24. Although theheat exchanger 10 has been illustrated as being rectangular, it could also have different shapes—for example it could have a circular disc-like configuration in some applications. - A variety of different types of turbulizers or flow augmentation means can be used in the
fluid conducting chamber 24, and in some applications, theturbulizer plate 16 may not be present. Furthermore, a short-circuit barrier different than crimpedbarrier 62 could be used in some embodiments. In this regard,FIGS. 8 and 9 show afurther shim plate 78 that could be used in place ofshim plate 14 in theheat exchanger 10. Theshim plate 78 has a centralelongate baffle wall 80 extending transversely upward therefrom to the cover plate 18 (not shown inFIG. 8 ). Thebaffle wall 80 is positioned between locations at which theflow openings FIG. 8 ) such that baffle wall causes the fluid inchamber 24 to follow an indirect U-shaped flow path as indicated byflow arrow 82. Thebaffle 80 is preferably formed from a portion of theshim plate 78 that has been stamped out along three side edges and then pivoted, upwards about a fourth side edge that remains connected to the rest of theshim plate 78, leaving arectangular opening 84 through theshim plate 78 that is sealably blocked by thesupport wall 38. Separate turbulizer plates, can be located on opposite sides of thebaffle wall 80. -
FIGS. 10 and 11 show askeletal baffle plate 86 that can be used inplace turbulizer plate 16 between shim plate 15 andcover plate 18 in a further alternative embodiment ofheat exchanger 10. The positions offlow openings skeletal baffle plate 86 are illustrated byphantom lines 28′ and 30′ inFIG. 10 . Theskeletal baffle plate 86 includes an outerrectangular frame 88 that is dimensioned to snugly fit within thesidewall flange 22 of thecover plate 18. Theskeletal baffle plate 86 has a height H (seeFIG. 11 ) that conforms to the height of thefluid chamber 24, and includes alternating substantiallyparallel baffle walls Baffle walls 90 extend from afirst end wall 94 near where theflow openings opposite end wall 96. Alternatingbaffle walls 92 extend from theopposite end wall 96 to close to thefirst end wall 94, such thatbaffle walls fluid chamber 24, as illustrated byflow arrows 98 inFIG. 10 (which assume that opening 28 is the higher pressure opening). In alternative embodiments, baffle walls such as those provided byskeletal baffle plate 86 could instead be provided by embossed ribs formed on theshim plate 14 or on thecover plate 18 or on both, and in many applications embossed ribs on the cover and/or shim plate will be preferred to a separate baffle plate as it reduces the number of components that need to be assembled. Numerous examples of embossed cover plate configurations suitable for use with theheat exchanger 10 are presented below. - In some applications, it may be desirable to use a fin plate that is lighter weight than extruded
fin plate 12. With reference toFIG. 12-14 , a further embodiment of a low profile heat exchanger, indicated generally byreference numeral 100, is shown in accordance with another preferred embodiment of the invention. Theheat exchanger 100 is similar toheat exchanger 10, except for differences that will be apparent from the following description.Heat exchanger 100 has a generally rectangular footprint, and as best seen inFIG. 13 , similar toheat exchanger 10, is a lamination of afin plate 102, ashim plate 104, and acover plate 106. In the illustrated embodiment, thecover plate 106 includes a rectangular central planarribbed portion 108 that is roll formed or stamped from braze clad aluminum or aluminum alloy. Asidewall flange 110 extends continuously about an outer periphery of the centralplanar portion 108 towards theshim plate 104, with an out-turnededge 112 of thesidewall flange 110 having a planer portion facing and sealably connected to theshim plate 104. Theshim plate 104 andcover plate 106 of theheat exchanger 100 collectively define therebetween afluid conducting chamber 113 that includes a flow path between a first flow opening 114 and a second flow opening 116 that are provided through thecover plate 106 at diagonally opposite corners thereof. On of theflow openings fluid conducting chamber 113, and the other is a fluid outlet. In the embodiment illustrated, eachopening corresponding fitting 122 that is brazed to thecover plate 106 and which has a flow passage through it that is parallel to the plane ofcentral portion 108. - The flow path between the
openings baffle ribs central portion 108 of thecover plate 106. In particular spaced apartparallel ribs 118 extend from afirst end 124 of thecover plate 106 to close to, but spaced apart from theopposite end 126 of thecover plate 106. Alternatingparallel ribs 120 extend from theend 126 to close to, but spaced apart from thefirst end 124. As best seen inFIG. 13 , each of theribs elongated sidewalls 128 that are joined together along their distal edges by aflat portion 130 having a planar surface for forming a good bond with theshim plate 104. -
Brackets 132 may be brazed to thecover plate 108 to permit theheat exchanger 100 to be fastened in place. Thebrackets 132 shown inFIGS. 12 and 13 each have a substantially rectangular central body with a portion that extends beyond the cover plate having a securinghole 134 therethrough. Thebracket center body 132 located on thecover plate 108 is dimensioned to run between twoadjacent ribs positioning tabs 136 that extend into theribs bracket 132 in place. In some applications, due to its light-weight configuration, the heat exchanger may be sufficiently supported by tubing connected to the inlet and outlet fittings, and additional brackets not required. - The
shim plate 112 is simply a flat rectangular plate formed from braze clad aluminum or aluminum alloy. Thefin plate 102 is secured to a side of theshim plate 112 that is opposite thefluid chamber 113 for drawings heat away from the fluid chamber, and is substantially rectangular, covering substantially the entire shim plate. Thefin plate 102 has one side that is secured to theshim plate 104 and an opposite side that is exposed. As best seen in the sectional view ofFIG. 13 and the bottom plan,view ofFIG. 14 , thefin plate 102 includes a plurality of spaced apart elongatedhollow fins 138 that extend outward from and run the length of theshim plate 104, each formed by a generally U-shaped wall. Thefins 138 define a plurality of openfaced air passageways 140, that are spaced apart by closed-face passageways 142 located within eachfin 138. The transverse ends of thefin plate 102 may be open so that the closed-face passageways 142 are open at opposite ends thereof. Each of theU-shaped fins 138 is connected to anadjacent fin 138 by a planar connectingwall 144 that is secured by brazing to theshim plate 104. In effect, theU-shaped fins 138 and connectingwalls 144 collectively form a square-corner corrugation. As seen inFIG. 14 , thefins 138 are formed to have a uniform size, but with soft undulating curves along their length to assist in interrupting the boundary layer of any air flowing therethrough. Thefins 138 are preferably light-weight and roll-formed or stamped from aluminum or aluminum alloy. In the illustrated embodiment, the alternating open-faced and closed-face passages -
FIG. 15 shows an example of a furtherfin plate structures 146 that could be used on the underside ofshim plate heat exchangers fin plate 146 has afirst side 148 that is brazed to the shim plate, and a second exposedside 150. A plurality of open-facedair passageways 152 run from afirst end 154 to asecond end 156 of thefin plate 146 between elongate fin structures that are made up of staggered or offset transverse rows ofconvolutions 158. The convolutions haveflat tops 160 to provide good bonds with theshim plate fin plate 146 is formed of expanded metal, namely aluminum, either by roll forming or a stamping operation. -
FIG. 17 shows a bottom view of yet another possible fin plate configuration. Thefin plate 162 ofFIG. 17 is the same asfin plate 102, except that the hollow U-shaped fins 164 (which define spaced-apart open-faced passages 166), are arranged in back and forth herringbone pattern. - In addition to the
cover plates FIG. 18 illustrates a furtherpossible cover plate 168 according to the present invention that is identical to thecover plate 18, with the exception that the alternating embossedribs ribs cover plate 106, and theribs arrows 174 betweenflow openings FIG. 18 , but without flow openings formed therethrough. Alternatively, both the cover plate and shim plate could have embossed ribs formed thereon that sealably abut together to define the flow path through the fluid chamber, in which case both the cover and shim plate would have a top and bottom plan view, respectively, similar to the plan view ofFIG. 18 (with the shim plate not having flow openings therethrough), with theembossed ribs - By way of example,
FIGS. 19 and 20 show afurther heat exchanger 190 that is substantially identical toheat exchanger 100, except that it has acover plate 192 in which are embossed a plurality ofdimples 194. Thedimples 194 extend to and engage theshim plate 104, thereby providing flow augmentation in thefluid chamber 113. - Yet another heat exchanger, indicated generally by
reference numeral 200, is shown in exploded view inFIG. 21 .Heat exchanger 200 is substantially identical toheat exchanger 100, with the exception of differences that are apparent from the drawings and the following description. Thecover plate 202 ofheat exchanger 200 does not include embossed ribs thereon for defining the flow path withinfluid chamber 113, but rather, a corrugated baffle plate 204 (formed from aluminum of another suitable material) is secured in thefluid chamber 113 between thecover plate 202 andshim plate 104. Thecorrugated baffle plate 204 includes a plurality of substantially parallel pairs of first andsecond barrier walls end 208 to anopposite end 210 of thefluid chamber 113. Thebarrier walls cover plate 202. (Orientational terms like “upper” and “horizontal” being used herein for explanatory purposes only as the heat exchanger can have any orientation in use). The pairs of barrier walls are joined together along their lower edges by afurther wall 214 that abuts against and is secured to theshim plate 104—in particular, thebarrier wall 206B of one pair is connected at the lower edge thereof to lower edge of thebarrier wall 206A of the adjacent barrier wall pair. A transverse flow opening 216 is provided at the end of eachbarrier wall 206A near theend 208 of the heat exchanger, and a transverse flow opening 218 is provided at the end of eachbarrier wall 206B near theopposite end 210 of theheat exchanger 200. Thus, parallel alternating flow passages are defined influid chamber 113 by thebarrier walls barrier wall openings - With reference to
FIG. 21A , in one embodiment, thecorrugated barrier plate 204 includes planarhorizontal portions 220 forming its outer longitudinal edges, and theportions 220 are sandwiched between the lower connectingflange 26 of thecover plate 202 and theshim plate 104. - With reference to
FIGS. 22-23C , further alternative cover plate and shim plate configurations for theheat exchanger 200 will now be discussed. Turning first toFIGS. 22 and 23 A, in one embodiment thecover plate 230 is dish shaped, having a centralplanar portion 240 having an integral, peripheral, downwardly extendingflange 242 that defines an angle of slightly greater than 90 degrees with respect to an inner surface of centralplanar portion 240. Theshim plate 236 is identical, except that it does not haveopenings flange 244 of theshim plate 236 is nested within and supported by theflange 242 of thecover plate 240, withfluid chamber 113 being defined between the planar central portions ofcover plate 240 andshim plate 236. The fin plate 102 (shown having fins with rounded corrugations rather than square) is secured to a lower surface of the planar central portion of theshim plate 244. Theshim plate flange 244 could be truncated just at or under the bottom edge ofcover plate flange 242 to minimize any adverse effect on air flow throughfin plate 102. -
FIG. 23B shows a similar configuration, except that theshim plate 238 has an upwardly turnedperipheral flange 246 that extends in the opposite direction ofcover plate flange 242, and which has an outer surface that is nested within and brazed to an inner surface ofcover plate flange 242. The configurations shown inFIGS. 23A and 23B could be easily “flipped over” with the fin plate being placed on the opposite side, as shown byphantom line 102′ inFIG. 23B . Furthermore, in some embodiments, fin plates may be used on both sides of the heat exchanger. -
FIG. 23C shows a further configuration in which thecover plate 234 andshim plate 248 are identical (except that there are no flow openings in the shim plate), each having an abuttingflange -
FIG. 24 shows afurther heat exchanger 260 that is identical toheat exchanger 100 except for the differences noted below. Thecover plate 262 ofheat exchanger 260 includes a plurality ofair flow openings 264 punched therethrough. Each of theopenings 264 is aligned with arespective opening 268 provided through theshim plate 266. Each cover plate air flow opening 264 is surrounded by awall 265 about its peripheral edge that extends from the cover plate to the shim plate to seal the air opening off from thefluid chamber 113. Thewalls 265 are preferably extruded from the cover plate material when theopenings 264 are punched. Alignedopenings fin plate 102 does not contact the shim plate, so that the aligned openings are not completely blocked by thefin plate 102. In some embodiments, corresponding openings may be punched through thefin plate 102. As illustrated inFIG. 26 , in use, air can flow through theopenings FIG. 26 , the heat exchanger may be angled relative to the direction of travel (arrow 270) in some applications to improve performance by increasing the attack angle at which air hits thefin plate 102. - Many components of the heat exchanger of the present invention have been described as being made from aluminum or aluminum alloy, however it will be appreciated that other metals could suitably be used to form the components, and in some applications non-metallic materials might be used, including for example thermally bondable, ultrasonically bondable, and adhesive bondable polymers. As will be apparent to those skilled in the art, many alterations and modifications are possible in the practice of this invention without departing from the spirit or scope thereof. Accordingly, the scope of the invention is to be construed in accordance with the substance defined by the following claims.
