Abstract:
1. A heat sink assembly, comprising: a heat pipe having a first heat-receiving surface and a cross section; a plurality of metal support members each being a flat plate of uniform thickness having a top side and a second heat-receiving surface at a bottom side parallel to the top side; a mounting spring plate having a bottom surface, a heat pipe mounting portion which is an inverted conical recess in the bottom surface with a cross section matching the cross section of the heat pipe, a plurality of support portions at the bottom surface, and a plurality of mounting portions for securing onto a base of a heat source, the heat pipe filling up the inverted conical recess of the mounting spring plate and directly secured thereto by solder-less press-fitting, the support portions being affixed to the top side of respective metal support members; wherein the first heat-receiving surface of the heat pipe protrudes outwardly and perpendicularly away from the bottom surface of the mounting spring plate so that the first heat-receiving surface of the heat pipe is parallel to and spaced from the bottom surface of the mounting spring plate, the second heat-receiving surfaces of the support members being flush with the first heat-receiving surface of the heat pipe.
