Abstract:
1. A heat dissipation device adapted for simultaneously dissipating heat from at least two heat-generating electronic components, comprising: a base comprising a supporting frame and at least two plates attached to a bottom of the frame for contacting the at least two heat-generating electronic components; a fin set comprising a plurality of fins on the base; and at least two groups of heat pipes respectively and thermally connecting the at least two plates and the fin set together; wherein the supporting frame comprises at least two spaced bridges, and defines at least one opening between the at least two bridges and two cutoffs beside the at least two bridges, respectively; and wherein each of the heat pipes is U-shaped in profile and comprises: an evaporating section sandwiched between one of the at least two plates and a corresponding bridge; and two condensing sections extending from two opposite ends of the evaporating section, one of the condensing sections passing through a corresponding one of the at least one opening to extend through the fin set, and the other condensing section passing through a corresponding one of the cutoffs or a corresponding another one of the at least one opening to extend through the fin set.
