Patent ID: 7870890

Claim:
A heat dissipation device for removing heat from a heat generating electronic device, the heat dissipation device comprising: a base adapted for thermally and physically engaging with the heat generating electronic device; a fin assembly consisting of a plurality of fins; a first heat pipe comprising two evaporation sections thermally and physically engaged in the base, two interconnecting condensation sections parallel to the evaporation sections and respectively thermally and physically inserted in a central portion of the fin assembly, and two connecting sections interconnecting corresponding condensation sections and the evaporation sections, the two condensation sections of the first heat pipe defining a first plane substantially parallel to the base; and a second heat pipe comprising two evaporation sections thermally and physically engaged in the base, two interconnecting condensation sections parallel to the evaporation sections and respectively thermally and physically inserted in an upper portion of the fin assembly far away from the base, and two connecting sections interconnecting corresponding condensation sections and evaporation sections of the second heat pipe, the two condensation sections of the second heat pipe defining a second plane substantially parallel to the base, the first plane being located between the base and the second plane.
