Abstract
A heat sink includes a plurality of spaced fins made of a thermally conductive material. Each of the fins has a through-hole surrounded by an annular wall. The annular wall is additionally provided with an axial slot which has a front end at a certain distance from a distal end of the annular wall and which extends to the related fin to form an aperture therein. A heat-conductive rod is inserted in the through-holes of the fins and fitted in the annular walls. Moreover, a bar is inserted in the apertures in the fins. The bar is made of low melting material so as to join the fins to the heat-conductive rod after the bar has been melt and then hardened.
Claims5
A heat sink comprising:
- a plurality of spaced fins made of a thermally conductive material, each of said fins having at least one through-hole surrounded by an annular wall projecting from said fin, said through-holes being aligned one with another;
- a heat-conductive rod inserted in said aligned through-holes and fitted in said annular walls of said fins;
- said annular wall being provided with at least one axial slot having a front end at a certain distance from a distal end of said annular wall, said axial slot extending to said fin to form an aperture in said fin;
- and
- a bar inserted in said apertures in said fins, said bar being made of low melting material so as to join said fins to said heat-conductive rod after being melted and then hardened.
