Description

Stacked heat conduction module

Technical field

The present invention refers to a kind of stacked heat conduction module especially relevant for a kind of heat conducting module.

Background technology

General heat abstractor comprises heat-conducting block, two or two above heat pipes and radiating fin group usually, is attached to offer two or more through holes on the heat-conducting block on the electronic heating component and wear for above-mentioned heat pipe.

And all must quite be particular about out of roundness in the processing of the manufacturing of heat pipe and through hole, and the through hole of being offered on the heat-conducting block is closed circle usually with corresponding circular heat pipe, the mode of general using milling processes the through hole on the heat-conducting block; Yet if utilize this kind mode to offer through hole on heat-conducting block, it is quite accurate that the tolerance of its processing must be affectedly bashful, because when heat pipe is arranged in the through hole, through hole must stay a small space, and scolder can be flowed among the through hole, and heat pipe is closely contacted with heat-conducting block; If the clear size of opening that mills out is too little, then heat pipe can't penetrate heat-conducting block, and must repeat processing; If the clear size of opening that mills out is too big, after then heat pipe penetrates heat-conducting block, space between heat pipe and the heat-conducting block is still too big, even utilize scolder that heat pipe is closely contacted with heat-conducting block, so just can reduce the heat transfer efficiency between heat-conducting block and the heat pipe, heat is lodged in amplexiform on the heat-conducting block of heating electronic building brick, even also can cause the overheated of electronic building brick to burn.

Therefore, how to overcome the shortcoming of aforementioned prior art, real is the present problem that needs to be resolved hurrily.

Summary of the invention

In view of this, main purpose of the present invention is to provide a kind of easy to assembly and stacked heat conduction module of saving manufacturing cost.

To achieve these goals, the invention provides a kind of stacked heat conduction module, comprise heat-conducting seat, stack block, cover plate and two or two above heat pipes, wherein, this stack block correspondence is spliced in this heat-conducting seat, and this cover plate correspondence is spliced in this stack block, and wherein the joint in this heat-conducting seat and this stack block offers at least one first perforation, joint at this stack block and this cover plate offers at least one second perforation, and this heat pipe is arranged in this first perforation and this second perforation respectively.

Stacked heat conduction module of the present invention is installed in heat pipe in first perforation and second perforation in the mode that compresses mutually by heat-conducting seat, stack block and cover plate, can reach effectiveness easy to assembly and that save manufacturing cost; Heat pipe is fixed in the mode that compresses by heat conducting module, heat pipe closely is pressed against in the heat conducting module, improve heat transfer efficiency; By groove is opening groove, comparatively convenient and save processing cost in processing, can reduce the whole manufacturing cost of heat conducting module; Can increase or reduce according to actual user demand by stack block, increase the applicability and the practicality of heat conducting module; The design of scolder running channel is used easily in the heat conducting module, solves heat pipe and the inconvenience that heat-conducting block welds in the known conductive structure, can improve the efficient of manufacture craft.
