Abstract

A cooling mechanism of high mounting flexibility includes a heat sink including a heat sink body defining an accommodation portion and position-limit sliding grooves and stop blocks fastened to the heat sink body, heat pipes positioned in the position-limit sliding grooves and stopped against the stop blocks, each heat pipe having a hot interface accommodated in the accommodation portion and an opposing cold interface positioned in one position-limit sliding groove, heat transfer blocks each defining a recessed insertion passage for accommodating the hot interfaces of the heat pipes and an opposing planar contact surface for the contact of a heat source of an external circuit board, and an elastic member elastically positioned between the heat sink and the heat transfer blocks.

First claim

What the invention claimed is:

1. A cooling mechanism comprising: a heat sink, a plurality of heat pipes, a heat transfer block, an elastic mounting lug, and an abutment plate; said heat sink comprising a heat sink body, said heat sink body comprising an accommodation portion, a plurality of position-limit sliding grooves extended from said accommodation portion, and a first screw hole located near said accommodation portion, said accommodation portion including an opening through said heat sink body; said elastic mounting lug comprising an elongated position-limit slot at one end and a circular first through hole located at an opposite end, wherein a first screw passes through said elongated slot and is received in said first screw hole to fasten the mounting lug to the heat sink body; said heat transfer block comprising a recessed insertion passaged located in one side thereof, a planar contact surface located at an opposite side thereof, and a positioning structure, said positioning structure comprising a plurality of second screw holes spaced around the recessed insertion passage, wherein a second screw passes through said circular through hole and is received in one of said second screw holes to fasten the heat transfer block to the elastic mounting lug, said heat transfer block is located in said accommodation portion; said abutment plate comprising a plurality of elastic protruding portions and a plurality of second through holes spaced around said protruding portions, wherein a plurality of third screws pass through said second through holes and are received in said second screw holes to fasten said abutment plate to said heat transfer block, and said abutment plate is located in said accommodation portion; said heat pipes each comprising a hot interface located at a first end and a cold interface located at a second end, wherein each of said cold interfaces is positioned in one of said position-limit sliding grooves, a plurality of stop blocks are fastened to said heat sink body to stop said heat pipes in said position-limit sliding grooves, and wherein said hot interfaces are located in said recessed insertion passage between and in direct contact with said heat transfer block and said protruding portions; wherein said cooling mechanism is configured such that said elastic protruding portions apply a pressure to said hot interfaces to press said hot interfaces against said heat transfer block; and wherein said cooling mechanism is configured such that said heat transfer block; said heat pipes, and said abutment plate move relative to said heat sink in response to a force applied to said planar surface.

2. The cooling mechanism of claim 1 , wherein a width of said position-limit sliding grooves of said heat sink is larger than the outer diameter of said heat pipes.

3. The cooling mechanism of claim 1 , wherein said heat sink body of said heat sink further comprises a plurality of mounting screw holes spaced around said position-line sliding grooves; each said stop block comprising a plurality of through holes, a plurality of fourth screws passing through said stop block through holes and received in said mounting screw holes to fasten said stop blocks to said heat sink body.

4. The cooling mechanism of claim 1 , wherein said heat sink is made from aluminum or copper.
