Patent ID: 7697293

Claim:
A heat dissipation device, comprising: a first heat sink comprising a plate-shaped spreader which is a flat heat pipe with a work fluid filled therein, adapted for contacting with a first heat-generating electronic component, and a honeycomb-shaped first fin unit thermally attached to the spreader; a second heat sink juxtaposed with the first heat sink; and a plurality of heat pipes thermally connecting the first heat sink and the second heat sink, the heat pipes each comprising a flat plate-shaped evaporating section sandwiched between the spreader and the first fin unit of the first heat sink, a condensing section extending in the second heat sink and a connecting section formed between corresponding evaporating and condensing sections, the connecting section comprising a first portion close to the evaporating section and a second portion close to the condensing section, the first portion being located at a plane different from that of the second portion.
