Abstract
The invention relates to a heat dissipating device which comprises a heat dissipating fin. One part of the heat dissipating fin forms a mounting part, and a heating element can be mounted on the mounting part. At least one side of the mounting part forms a heat dissipating section, and a plurality of heat dissipating holes are formed in the surface of the heat dissipating section. Air can flow freely through the heat dissipating holes and taking the heat energy on the surface of the heating element out in a mode of natural heat convection, and convection dead corners in which air cannot circulate smoothly do not exist, and thus heat dissipating efficiency is higher.
Description
Technical field
The present invention is about a kind of heat abstractor, espespecially a kind ofly is equipped with the heat abstractor of a plurality of louvres in the patch conductor surface for electronic installation.
Background technology
The heater element of electronic installation inside (for example: light-emitting diode) can produce heat energy when using, and the higher electronic installation of power, the heat energy that its heater element sends is higher, if immediately do not dispel the heat, electronic installation may reduce useful life or fault, therefore heat abstractor need to be set on electronic installation, the heat energy that produces during the electronic installation operation dispels the heat by heat abstractor.
see also Fig. 8 and shown in Figure 9, be a kind of heat abstractor common in prior art, it is the aluminium alloy compression casting moulding, the substrate 41 of cylinder 40 inside can be installed for heater element 50 and arrange, separately in the cylinder 40 outside projections in bottom surface, base plate 43 is arranged, between its cylinder 40 outer side surfaces and base plate 43 around the radiating fin 42 that is provided with a plurality of intervals and arranges, when reality is used, when this heater element 50 sends heat energy, borrow substrate 41 with thermal energy conduction to radiating fin 42 places, ventilate in the spacing place of 42 of adjacent radiating fins, and the heat energy on radiating fin 42 surfaces is taken away with the form of thermal natural convection dispel the heat simultaneously.
Yet, after using, reality finds, the junction of this radiating fin 42, base plate 43 and cylinder 40 can be formed with convection current dead angle 44, air can't circulate in 44 places, convection current dead angle smoothly, therefore can't make heat abstractor effectively dispel the heat with the form of thermal natural convection, cause it to have the not good shortcoming of radiating efficiency.
The designer is the shortcoming that air is dispelled the heat with the thermal natural convection swimmingly because heat abstractor of prior art has that the poor and heat-delivery surface of radiating efficiency has the convection current dead angle just, and designs the present invention.
Summary of the invention
Purpose of the present invention namely is to provide a kind of heat abstractor, the heat abstractor that dispels the heat with the thermal natural convection form that especially a kind of radiating efficiency is higher.
The purpose of the invention described above, realized by following technology:
The present invention is a kind of heat abstractor, includes a fin;
The part lamellar body of this fin forms can be for the installation portion that heater element is set, and at least one side lamellar body of this installation portion is bent to form radiating part, is penetrated with a plurality of louvres in the surface of this radiating part.
Heat abstractor as above, this louvre are square hole or hex hole.
Heat abstractor as above, the sheet surface of the sheet surface of this radiating part and installation portion lays respectively on distinct plane.
Heat abstractor as above, the lamellar body of this radiating part be with the jagged lamellar body with a plurality of turnovers that is bent to form, also or the lamellar body of this radiating part bends with circular arc towards the direction of installation portion.
Heat abstractor as above further includes time fin, the part lamellar body of this time fin forms the department of assembly, at least one side lamellar body of this department of assembly is bent to form radiating part, surface in the radiating part of this time fin is penetrated with a plurality of louvres, and the department of assembly of this time fin is connected in a side of the installation portion of this fin.
borrow above-mentioned technological means, the present invention is on being installed on heater element the time, the heat energy that this fin can produce heater element, conducting to via the lamellar body of installation portion the radiating part that is positioned at the fin dual-side dispels the heat, and because a plurality of louvres that the radiating part surface is run through, this louvre can be designed to square hole, hex hole or other forms of perforation are (as polygon, geometry etc.), air free is circulated in each louvre, in the thermal natural convection mode, the heat energy on heater element surface is taken out of, compared to the shortcoming that has the convection current dead angle between the radiating fin of prior art aluminium die cast heat abstractor, fin surface of the present invention can not be formed with the convection current dead angle, can have better radiating efficiency.
The bent formation zigzag in sheet surface of this fin, make the lamellar body of this radiating part can borrow bending and have larger area of dissipation under identical whole height, the general direction of radiating part can be designed to along the direction setting of parallel this installation portion sheet surface, by this under the prerequisite with certain area of dissipation, can reduce the height of heat abstractor integral body, conveniently to be arranged in electronic installation.
The bent formation of the lamellar body of this fin is circular-arc, is convenient to be applied in the field of fluorescent tube.
This fin can further connect time fin, and the heat energy that radiating part that by this can be by fin and the radiating part of time fin produce heater element simultaneously dispels the heat.
