Patent ID: 7269014

Claim:
A heat dissipation device for a heat-generating electronic component, comprising: a heat spreader having a bottom surface adapted for thermally contacting the electronic component and a top surface opposite to the bottom surface; a conducting member thermally coupled with the top surface of the heat spreader, with a plurality of first fins extending downwardly from a top of the conducting member, pointed toward a base of the conducting member and spaced from the base a distance, a plurality of first passages formed between the first fins and extending along a front-to-back direction, the conducting member comprising an upper base plate at the top, a lower base plate at the base and spaced from the upper base plate a distance, and a connecting portion interconnecting the upper base plate and the lower base plate; a plurality of second fins extending upwardly from the top of the conducting member, a plurality of second passages formed between the second fins and extending along the front-to-back direction; a fan mounted on a back side of the first and second fins, the fan providing airflow to the first and second fins along the front-to-back direction; and a heat pipe thermally connecting the heat spreader with the conducting member and the second fins, the heat pipe comprising an evaporating portion sandwiched between the heat spreader and the lower base plate and a condensing portion sandwiched between the upper base plate and the second fins, wherein the evaporating portion and the condensing portion of the heat pipe are parallel to each other and extend along a lateral direction perpendicular to the front-to-back direction.
