Embodiment

For further setting forth the utility model is to reach technological means and the effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, to according to its embodiment of radiator, structure, feature and the effect thereof that the utility model proposes, describe in detail as after.

Relevant aforementioned and other technology contents, characteristics and effect of the present utility model can clearly present in the following detailed description that cooperates with reference to graphic preferred embodiment.For convenience of description, in following embodiment, components identical is represented with identical numbering.

See also Fig. 1 and Fig. 2, disclosing respectively has stereogram of the present utility model and exploded perspective view.

The utility model is a kind of radiator, and it mainly includes a pedestal 10 and a lid 11.

In a possible embodiments, aforementioned pedestal 10 be formed with a upper surface and one in order to the lower surface of an electronic component thermo-contact, the surface is formed with a groove 101 thereon, aforementioned pedestal 10 is long and narrow and has a front end and a rear end.Aforementioned pedestal 10 with its rear end thermo-contact in an electronic component.Produce heat when the energising running not shown in the figures of this electronic component, its the heat that produces then be transmitted to this pedestal 10 rear ends by the relation of thermo-contact, it is all to diffuse to this pedestal 10 by this rear end again, in order to do making this pedestal 10 can cooperate radiating requirements to install corresponding heat abstractor with further lifting radiating effect in its front end.

Be covered on the groove 101 of aforementioned pedestal 10 to aforementioned lid 11 form fit, between aforementioned lid 11 and aforementioned groove 101, form a heat transfer space, thereby can bring into play the effect of heat-transfer pipe, significantly strengthen the effect of conducting heat towards pedestal 10 rear ends by aforementioned pedestal 10 rear ends.

On the other hand, because these lid 11 structures are simple, and need not in inner sustain vacuum own or low pressure state.Therefore when making this lid 11, can make it form the shape that cooperates aforementioned groove, to reach the effect with groove 101 certain driving fits of aforementioned pedestal 10, and by coupling and the driving fit structure of aforementioned lid 11 with aforementioned groove 101, allow have suitable structural strength between the two, be difficult for causing fault or damage because of breaking away from mutually.

Again with regard to a feasible manufacture method, can make aforementioned lid 11 be formed with an opening 111 with respect to aforementioned pedestal 10 front end places, earlier that a heat conducting element is not shown in the figures and a conductive fluid is not shown in the figures, be provided with respectively or be placed in the aforementioned groove 101, aforementioned lid 11 that will mate mutually again and aforementioned groove 101 are in modes such as punching press or bondings, make both form the structure of mutual driving fit, multiple bleed and seal aforementioned opening 111, make the heat transfer space that is formed between aforementioned lid 11 and the aforementioned groove 101 become vacuum or low pressure state from aforementioned opening 111.Wherein aforementioned heat conducting element can be in the aforementioned groove 101 corresponding to the set plural fiber of aforementioned pedestal 10 front ends and rear end, or a mesh element that cooperates aforementioned groove 101 shapes.

By said structure, when using the utility model, the heat that electronic component produced that aforementioned hot is contacted with aforementioned pedestal 10 rear ends reaches this pedestal 10 earlier, makes the aforementioned conductive fluid that is positioned at rear end be heated and move along aforementioned heat conducting element towards front end; When conductive fluid after front end cooling, resurgent goes back to the rear end and is heated once again.So go round and begin again, can bring into play potent heat transmission function.

See also Fig. 3 and Fig. 4, disclosing respectively has the utility model at the exploded perspective view of looking up angle and sectional side view.

In order to cooperate the different various electronic components of size shape, can be at the chimeric heat-conducting plate 12 of the lower surface of aforementioned pedestal 10, and by this heat-conducting plate 12 and the thermo-contact of aforementioned electronic element, more effectively the heat that electronic component was produced is reached on the aforementioned pedestal 10.In a possible embodiments, aforementioned heat-conducting plate 12 is located at this place, pedestal 10 nearly its rear end, and can adopt the metal material or the alloy material that help conducting heat such as copper material or copper alloy etc., and can make it form the shape that cooperates electronic component, to allow the heat of electronic component can be guided to aforementioned pedestal 10 effectively comprehensively.

In addition and since now many electronic components be arranged at a circuit board not shown in the figures on, pedestal 10 of the present utility model can extend outward more than one extension 102 in order to setting firmly this pedestal 10.The shape of this extension 102 can be used needs and be designed to required shape, and at least one structure 103 that sets firmly can be set on aforementioned extension 102.In a concrete possible embodiments, the aforementioned structure 103 that sets firmly forms screw, by wear double-screw bolt not label in the aforementioned screw that sets firmly structure 103 that is adopted as, and make this double-screw bolt be arranged on the aforementioned circuit plate, can set firmly aforementioned pedestal 10 simple and effectively, concern with the relative position of this electronic component and the thermo-contact of keeping therebetween to fix this pedestal 10.Particularly, can make aforementioned extension 102 towards extension all around, and on the end of its extension, form one respectively as the screw that sets firmly structure 103.

Concrete structure of the present utility model from the above and using method, the utility model forms groove 101 and cooperates driving fit lid 11 thereon can bring into play potent heat-transfer effect and give its suitable structural strength on pedestal 10, really the purpose of attainable cost utility model.
