ABSTRACT:
A heat dissipation device includes a base for thermally engaging with an electronic device, a fin assembly including of multiple fins, a first heat pipe and a second heat pipe. The first heat pipe includes two evaporation sections engaged in the base, two interconnecting condensation sections parallel to the evaporation sections and respectively thermally inserted in a central portion of the fin assembly, and two connecting sections interconnecting corresponding condensation sections and the evaporation sections. The second heat pipe includes two evaporation sections engaged in the base, two interconnecting condensation sections parallel to the evaporation sections and respectively thermally 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.
