Patent ID: 7495915

Claim:
A heat dissipation system used for dissipating heat generated by an electronic device mounted on a printed circuit board over a base plate of an enclosure of an electronic equipment, the heat dissipation system comprising: a spreader adapted for contacting the electronic device for absorbing heat generated by the electronic device, the spreader defining a channel therein; a plurality of fins located at one side of the printed circuit board opposite the spreader and thermally attaching to the enclosure; and a heat pipe having two ends, one end of the heat pipe being received in the channel of the spreader, another end of the heat pipe extending through the fins, whereby a part of heat generated by the electronic device is transferred to the enclosure via the heat pipe and the fins; wherein the fins are located in a space beneath the printed circuit board, sandwiched between the printed circuit board and the base plate of the enclosure and abut against the base plate of the enclosure.
