Patent ID: 7866376

Claim:
A heat dissipation device for removing heat from a heat generating electronic device, the heat dissipation device comprising: a base comprising a top face and a bottom face at opposite sides of the base, the bottom face of the base being adapted for contacting the electronic device and absorbing the heat therefrom; a fin set comprising a bottom thermally contacting the top face of the base for dissipating the heat in the base and an upper portion apart from the bottom, the bottom of the fin set being larger than the top face of the base; a first s-shaped heat pipe comprising a first transferring portion thermally and physically engaging with the base, having a first end and a second end, a second transferring portion extending from the first end of the first transferring portion and projecting beyond the base, the first and second transferring portions of the first s-shaped heat pipe each comprising a flat top face contacting thermally and physically the bottom of the fin set for transferring the heat of the base to the entire bottom of the fin set, a third transferring portion, extending from the second end of the first transferring portion, the third transferring portion projecting beyond the base and having a flat top face thermally and physically contacting the bottom of the fin set, the first transferring portion, the second transferring portion, and the third transferring portion are all parallel to each other, all located in the same plane, and are all parallel to the base; and a second u-shaped heat pipe comprising an evaporation portion thermally and physically engaging with the base and a condensation portion extending from the evaporation portion and thermally and physically engaging with the upper portion of the fin set, the second u-shaped heat pipe being adapted for transferring the heat of the base to the upper portion of the fin set.
