COMBINED INSULATING AND COOLING BLANKET Filed Nov. 5, 1962 2 Sheets-Sheet 2 f/ 4 50A W6 GEoRGElNc/ESSNBERG fana ml/L EDWARD F. DOYLE BY Mvg/NM i AGENT United States` Patent O This invention relates to an insulating and cooling blanket combination and more particularly to a flexible blanket containing a refrigerant, which blanket includes means for allowing the escape of gaseous substances generated by the boiling of the refrigerant.
It is an object of this invention to provide an insulating and cooling blanket combination which does not require external power to cool and insulate a member.
It is still a further object of this invention to provide a flexible blanket comprising a cooling device formed by a plurality of cells, each of which contain a section of wick material and a chamber adjacent the wick material.
We have found that an insulating and cooling blanket, made in accordance with the present invention, has exhibited extremely good insulating and cooling characteristics without the requirement of an external power supply system. This has been accomplished by constructing a fluid retaining cell comprising a layer of wick material for retaining iluid refrigerant disposed adjacent to a chamber for receiving the gaseous substance when the liquid is boiled ott. The cells may be formed from a iiexible material such as plastic or any other suitable synthetic and are joined to form a blanket to tit closely to the contour of the surface of the member to be cooled. By virtue of the refrigerant changing from a liquid phase to a gaseous phase, an eiiicient cooling system has been devised. Means are provided for collecting the gaseous substance so that it may be vented out of the insulating blanket.
Other features and advantages will be apparent from the specification and claims and from the accompanying drawings which illustrate an embodiment of the invention.
FIGURE l is a cross-sectional View showing the details ot the cells.
FIGURE 2 is a partial plan View of a modiiied version of the device shown in FIGURE l.
FIGURE 3 is a partial sectional View taken along the line 3-3 ot FIGURE 2.
FIGURE 4 is a perspective view showing the device in FGURE 2 which is assembled to insulate a cylindrical member.
FIGURE 5 is a partial sectional view taken along line 5-5 of FIGURE 4.
Reference is now made to FIGURE l, which shows theV present invention as comprising a plurality of cell members indicated by the numeral 10, consisting of members 12 and 14 which may be formed from a flexible material such as plastic or a synthetic or the like. Members 12 and 14 are joined together at their ends to form a sealed chamber. A porous or pierced middle layer 16 extends across the chamber and is fastened between the under and upper layers and is secured around its outer surface by cement, welding, rivets, or other suitable means to deline a pair of chambers. A plurality of cells are fastened together by any suitable fastener indicated generally by numeral 13 to form a flexible body. Obvious-V 3,180,111 Patented Apr. 27, 1965 "ice It is to be understood that once the wick material is filled with the liquid, the manifold is closed off to prevent escaping of the liquid. An insulating blanket of any known construction may overlie VVthe top surface of the cells to form an outer layer 26. The combined insulating and cooling blanket may then be iitted around the surface of the device intended to be cooled. When the device intended to be insulated and cooled becomes sufficiently hot, the liquid in cham-ber Ztl will change to a gaseous state and effectively reduce the temperature of the member to be cooled. The vapor passes through middle layer d6 into chamber 21 and is bled od through the vapor vent 28 which communicates with chamber 21 through passages 30. It will be appreciated that the size of the cells is selected -by considering the use for which the blanket is intended to be employed; for eX- ample, if the blanket is intended to be used for insulating ammunition such as missiles and the like, which are subjected to g-loadings acquired by virtue of transporting such ammunition, the size of the cell is made suiiiciently small so that the g-loads will not adversely affect the capillary action of the Wick material. That is to say that the cells are not oversized so that the g-loadings will force the moisture in a position in the cell so that the wick can no longer support the fluid by capillary action. Also, connecting line 24 and inlet manifold 22 may be eliminated by lilling through steam vent 28 and passages 30. Vapor vent 28, passages 30, chamber 21 and chamber 20 are all flooded and then vapor vent 28, passages 30 and chamber 21-are drained out the bottom. The wick holds fluid in chamber 20 by capillary action. FIGURES 2-5 show a modification of the present invention wherein the cells are formed by a plurality of rings or hollow disk members which may be formed from a glass silicon material or other synthetic material or the like. The rings or hollow disk members may be formed into two diameters. As is shown Vin FIGURE 3, the larger diameter rings 50 are connected to the smaller diameter rings 52 andmay be bonded together by a suitable cement such as one of the epoxides. As shown in FIG- URE 3, the hollow disk members are mounted so that the larger disks lie in a different plane than the smaller rings.
As noted from the drawing, when the cells are sand-I wiched between the insulating blanket and the body to be cooled and insulated, small pockets are formed. Vr[his serves to form vent chambers for receiving the gaseous substance when the liquid refrigerant changes from one phase to another. The wick material is inserted into the larger diameterl disk, and the material may be of any Well known substance, such as iiberglas matting.
As is shown in FIGURE 5, the cells are sandwichedbee tween the outer surface of the member 54 intended to be cooled and an insulating blanket 56 of any known construction. As shown in FiGURE 5, it will be appreciated that by virtue of placing the larger diameterl rings in a diiterent plane than the smaller diameter rings, the face of the larger diameter rings forms a surface for itting the contour of the member 54, while the top face of the smaller diameter ring forms a surface for receiving the surface of the insulating blanket. VThis tit defines chambers S8 which serve to receive the vapor or gaseous substance generated by the liquid refrigerant..
` FIGURE 4 shows the cooling and insulating blanket in its assembled form as it would be applied for the purpose of cooling and insulating the member 54. Thus, as was noted in the description of FIGURE l,.in the event thatvthe temperature of member 54 increasesY beyond the Y i point where therefrigerant begins to boil, the refrigameter Cells and 'escapes out of theblanket by passages' 6) formed in the insulating member 56.
Filling of the insulating and cooling blanket of the type shown in FIGURES 2-5 may be accomplished by directing refrigerant through vented, then draining out any excessive refrigerant that wasnot absorbed by the wicks. The wicks hold the useable change of fluid by capillary action.
