Abstract:
1. A heat sink with heat pipes comprising: a base comprising a bottom surface for contacting with a heat-generating electronic component, an upper surface opposite the bottom surface, and a plurality of grooves defined in the upper surface of the base; a plurality of heat pipes received in the grooves, respectively, each heat pipe comprising an evaporating section and a condensing section; and a fin assembly attached on the bottom face of the base corresponding to the condensing sections of the heat pipes; wherein the evaporating sections of the heat pipes are closely arranged on a portion of the base adjacent to an end of the base and in alignment with the heat-generating component for thermally connecting with the heat-generating component, and wherein the condensing sections of the heat pipes extend away from said portion of the base to another end of the base; wherein the heat pipes comprise a pair of U-shaped heat pipes each defining an opening side facing toward each other, and one of the evaporating section and the condensing section of one of the heat pipes is located between the evaporating section and the condensing section of another one of the pair of heat pipes.
