Abstract

The utility model relates to a stacked radiator for an electronic element. The utility model is produced for providing the radiator which has the advantages of low height, small size, and low cost and has the advantage of being suitable for electronic elements with different specifications. The utility model is composed of a plurality of heat radiating fin bodies which are stacked, wherein, both sides of a heat conducting seat of each heat radiating fin body are additionally extended with lateral plates which are folded and formed; clamping and buckling parts which are upwards folded are respectively punched on the plate surfaces of the lateral plates; the heat radiating fin bodies are stacked in sequence, and the clamping and buckling parts of the lower heat radiating fin bodies and the neighboring clamping and buckling parts of the upper heat radiating fin bodies are mutually embedded.

Description

The stacked-up type electronic component radiator

The utility model belongs to radiator, particularly a kind of stacked-up type electronic component radiator.

In electronic equipments, by radiator the heat conduction that electronic component produces is spread usually,, prevent that electronic component from damaging because of overheated to prolong the useful life of electronic component.Along with progress of science and technology, people make every effort to gently, approach for every article, so that carry, the notebook computer that is widely used especially day by day, its overall volume is light and handy, is subjected to consumer's favor especially deeply.Yet the radiator in the various computer of commonly using comprises with aluminium block and extrudes the pedestal that forms and number from the upwardly extending heat-dissipating fin of pedestal.When group is established, adhere on electronical elements surface with pedestal, to absorb the heat that is produced when electronic component operates, will be through heat-dissipating fin with the heat diffusion that absorbs.Though this radiator of commonly using can provide the effect to electronic element radiating, but owing to connect with pedestal between its heat-dissipating fin, therefore its ccontaining height is higher and can't reduce, thus, just make in the computer global design and be restricted, and can't reduce its overall volume and thickness, cause the consumer to carry inconvenience; In addition,, when applying to the electronic component of different size, just need die sinking separately to make, increase manufacturing cost because the radiator of commonly using is that therefore, its specification is a fixed form with the aluminium extrusion forming.

The purpose of this utility model provides that a kind of height is low, volume is little, cost is low, is applicable to the stacked-up type electronic component radiator of different size electronic component.

The utility model is served as reasons, and lamellar body is stacked forms in several pieces heat radiations; The heat-conducting seat both sides of heat radiation lamellar body extend the stubborn side plate that is converted into shape, dash respectively to be provided with the upwards clamping part of turnover on the plate face of side plate; Number heat radiation lamellar body is stacked in regular turn, and chimeric mutually with below fin body clamping part and adjacent top heat radiation lamellar body clamping part.

Wherein:

The clamping part top is to bend the bending lamellar body that forms cramp, and the clamping part lower edge dashes and is provided with button hole corresponding with cramp and can be chimeric.

Clamping part is that medial surface dashes the straight lamellar body that is provided with salient point, and the clamping part lower edge dashes and is provided with button hole corresponding with salient point and can be chimeric.

Several pieces dispel the heat because the utility model is served as reasons, and lamellar body is stacked to form; The heat-conducting seat both sides of heat radiation lamellar body extend the stubborn side plate that is converted into shape, dash respectively to be provided with the upwards clamping part of turnover on the plate face of side plate; Number heat radiation lamellar body is stacked in regular turn, and chimeric mutually with below fin body clamping part and adjacent top heat radiation lamellar body clamping part.During manufacturing, with the module of continuous punching press with strip one by one punching out become the heat radiation lamellar body.During assembling, will be stacked in regular turn with the number heat radiation lamellar bodies of the corresponding quantity of specification of electronic component, and chimeric mutually with the dispel the heat button hole of lamellar body clamping part of below fin body clamping part and adjacent top.During use, side side plate with the stacked chimeric lamellar body that respectively dispels the heat of the utility model is horizontally placed on electronical elements surface with the utility model, and fixed, the heat that electronic component produced can be directly conducts to each heat-conducting seat respectively and is spread via the side plate with the lamellar body that respectively dispels the heat of its applying, because of the pedestal of commonly using radiator need not be set, can reduce its ccontaining height significantly.Not only highly low, volume is little, cost is low, and is applicable to the different size electronic component, thereby reach the purpose of this utility model.

Fig. 3, be the utility model user mode schematic diagram.

Fig. 4, be fin body structure schematic isometric (clamping part is provided with salient point) in the utility model.

Below in conjunction with accompanying drawing the utility model is further elaborated.

As shown in Figure 1 and Figure 2, the utility model several pieces heat radiation lamellar body 10 stacked forming of serving as reasons.Heat-conducting seat 11 both sides of heat radiation lamellar body 10 extend the stubborn side plate 12 that is converted into shape, on the plate face of side plate 12, dash respectively and be provided with the upwards clamping part 13 of turnover, clamping part 13 is the cramp 15 bending lamellar bodies that bend formation for the top, and clamping part 13 lower edges dash and are provided with button hole 14 corresponding with cramp 15 and can be chimeric.

Also can be as shown in Figure 4, the clamping part 16 of heat radiation lamellar body 10a dashes the lamellar body that is provided with salient point 17 for medial surface, and clamping part 16 lower edges are towards being provided with button hole 14 corresponding with salient point 17 and can be chimeric.

During manufacturing, with the module of continuous punching press with strip one by one punching out become heat radiation lamellar body 10 (10a) shown in Fig. 2 (Fig. 4).

During assembling, as shown in Figure 2, will be stacked in regular turn with the number heat radiation lamellar bodies 10 (10a) of the corresponding quantity of specification of electronic component, and chimeric mutually with the cramp 15 (salient point 17) of below fin body clamping part 13 (16) with the button hole 14 of adjacent top heat radiation lamellar body 10 (10a) clamping part 13 (16), to form the utility model.

During use, as shown in Figure 3, with a side side plate 12 of the stacked chimeric lamellar body 10 (10a) that respectively dispels the heat of the utility model the utility model is horizontally placed on electronical elements surface, and is fixed.At this moment, the heat that electronic component produced can be directly conducts to each heat-conducting seat 11 respectively and is spread via the side plate 12 with the lamellar body 10 (10a) that respectively dispels the heat of its applying, because of the pedestal of commonly using radiator need not be set, can reduce its ccontaining height significantly.
