Abstract

The utility model relates to a combined type radiating fin, comprising a plate body made of heat conducting material such as aluminum, copper or graphite. An opening with a plurality of intervals is made on a side of the plate body; a link part is arranged on the other side of the plate body. The surplus material of the openings kink upside and forms a plurality of radiating fins. The opening of the plate body interleaves with the opening of the other plate body, which can facilitate the combination of the two plate body and forms a whole radiating fin. The size of the link part can be made larger to be used directly on different kinds of heat generating component, thus can improve the heat radiating applicability of the radiating fin. The utility model has the advantages that as the two plate body can be inserted into each other to form a complete radiating fin, the manufacturing cost can be effectively reduced, and as the radiating fin can be kinked to the surface of the heat generating component, thus the heat radiating efficiency is greatly improved.

Description

The combined type radiating fin

Technical field

The utility model relates to a kind of combined type radiating fin, refers in particular to a kind of contact area that increases with electronic heating component, the radiating fin that also can cooperate bending to change according to the photoelectric heating component external form.

Background technology

Progress along with science and technology, the execution speed of electronics implements (as main frame, personal digital aid (PDA) etc.) is more and more fast, but it is also more and more higher with respect to the temperature that is produced in the electronics implements, for the temperature that is produced in the electronics implements is effectively distributed outside system, reach each assembly of keeping in the electronics implements and operate under allowable temperature, cooling system has become indispensable main accessory in the present electronics implements.

See also shown in Figure 1, it is a kind of schematic perspective view of known heating radiator, several is the heating radiator 10 of bending by metal material punching out such as aluminium or copper for it, this heating radiator 10 can glue together with an electronic heating component (figure slightly), operate under allowable temperature so as to helping electricity effectively to distribute outside system, reach to keep electronic heating component in the temperature that heat generating component produced.

But above-mentioned known heating radiator 10 is because several groove 101 at interval, so, cause reducing the area that glues together with electronic heating component, and then reduce the radiating effect of this heating radiator 10.

See also shown in Figure 2, it is the three-dimensional exploded view of another kind of known heating radiator, the heating radiator 11 that the fastener 112 that it becomes several pieces " Contraband " template bodies 111 and concave, convex to match by metal material punching out such as aluminium or copper combines, this heating radiator 11 can glue together with an electronic heating component (figure slightly), operate under allowable temperature so as to helping the temperature that electronic heating component produced effectively to distribute outside the dry systems, reach to keep electronic heating component.

But, though above-mentioned known heating radiator 11 increases and electronic heating component gummed area, but because the fastener 112 mutual buckles that this concave, convex matches, cause whole heating radiator 11 to bend, and now electronic heating component because of more and more polynary change, such as electronic heating components such as heat pipes,, cause reducing the usability of this heating radiator 11 because of this heating radiator 11 can't bend.

So as from the foregoing, above-mentioned known combined type radiating fin in the use of reality, obviously has inconvenience and exists with shortcoming, and can wait to be improved.

Summary of the invention

The purpose of this utility model is to propose a kind of combined type radiating fin of being made up of at least one plate body with multiple tracks spaced openings, and it can increase the contact area with radiating subassembly, improves radiating efficiency, thereby has solved the existing in prior technology problem.

The technical scheme that the utility model adopted is that it is made of the plate body of a slice at least, this plate body one side is several spaced apertures of punching out, opposite side is provided with a linking part, the clout of this several opening and upwards bending, forming the radiating fin of several vertical type lamellar body, and reach good radiating efficiency whereby.

Advantage of the present utility model is:

(1) the opening clout of this plate body is upwards bending, to form several radiating fin, so as to lowering the clout consumption of this two plate body, effectively reduces the material cost of this plate body.

(2) can bend change according to the heat generating component external form, improve the applicability of complete radiating fin, reach significantly and reduce production costs.

(3) can increase contact area with heat generating component, and the more effect of quick heat radiating of heat generating component is provided.

Embodiment

Further specify preferred embodiment of the present utility model in conjunction with above-mentioned each accompanying drawing now.See also shown in Figure 3, the utility model is tailored the plate body 20 that forms by Heat Conduction Materials such as aluminium, copper or graphite, this plate body one side is by several spaced apertures 21 of machine punching out such as punch press, these plate body 20 opposite sides are provided with a linking part 22, the clout of this several opening 21 and upwards bending, to form several radiating fin 211, the radiating fin 211 of upwards bending and the clout consumption that can lower this plate body 20 are so as to reducing the material cost of this plate body 20.

See also Fig. 3 to shown in Figure 5, the opening 21 of this plate body 20 is also interlaced with the opening 21 of another plate body 20, can plant mutually with convenient two plate bodys 20, and so as to forming complete radiating fin 30, this complete radiating fin 30 can glue together with heat generating component (figure slightly) by heat-conducting glue (scheming slightly), can effectively distribute outside system with the temperature that helps heat generating component to produce, reach and keep heat generating component and under allowable temperature, operate, the linking part 22 of this radiating fin 30 can increase or reduction (as shown in Figure 7) according to heat generating component (figure slightly) area, to meet the practicality of this radiating fin 30.

See also shown in Figure 6, the linking part 22 of this plate body 20 is to make things convenient for the user to bend, use to cooperate different external forms such as heat generating component, so as to improving the applicability of this complete radiating fin 30, avoiding different heat generating components is the expense that must develop different radiating fins 30, effectively reaches significantly to reduce production costs.

In sum, when knowing that combined type radiating fin of the present utility model had industry applications, novelty and progressive, innovation structure of the present utility model again also never sees like product and public use.

But above-described only is preferable possible embodiments of the present utility model; be not so promptly inflexible limit practical range of the present utility model; so the equivalent structure that uses the utility model instructions and accompanying drawing content to be done such as changes, or directly or indirectly apply to the protection domain that other relevant technical field all in like manner all is contained in the utility model claims.
