Patent ID: 8225847

Claim:
A heat dissipation device for cooling an electronic device, comprising: a conductive plate; a heat spreader received in the conductive plate and comprising a first face for contacting the electronic device and a second face opposite to the first face; a heat pipe contacting the conductive plate and comprising an evaporating section received in the conductive plate and located between the first face and the second face of the heat spreader; and an elastic member mounted on the conductive plate for exerting an elastic force on the heat spreader and the heat pipe in the conductive plate toward the electronic device; wherein the heat spreader surrounds the heat pipe, and the elastic member impels the heat pipe by contacting the heat spreader; and wherein the heat spreader comprises a top sandwiching plate, a bottom sandwiching plate parallel to the top sandwiching plate, and a connecting plate interconnecting the top sandwiching plate and the bottom sandwiching plate, wherein the heat pipe is sandwiched between the top sandwiching plate and bottom sandwiching plate, and the first face is formed at a bottom of the bottom sandwiching plate, and the second face is formed at a top of the top sandwiching plate.
