Patent ID: 7365989

Claim:
A heat dissipating device adapted for dissipating heat generated by an add-on card, comprising: a base located on the add-on card and contacting with a chipset attached on the add-on card, for dissipating heat generated by the chipset, the base defining a slot therein, the slot being above and adjacent to the chipset; a cover attached on the base and having a top wall spaced from the base; a plurality of fins thermally connecting the cover and the base; and a fan positioned on a surface of the base for driving an airflow; the slot is located on the surface of the base between the fins and the fan; a heat pipe is mounted on the surface of the base, and thermally connects with the base and the fins, wherein one portion of the airflow flows through the fins and another portion of the airflow flows through the slot and blows other electronic components near the chipset.
