Abstract
A heat dissipating device mounted onto a VGA card (10) includes a base (22) contacting with a GPU (12) attached on the VGA card, a cover (21) mounted on the base, and a plurality of fins (24) received between and thermally connecting the cover and the base. The base defines a slot (222) above the GPU. A fan (28) is positioned on the base for driving an airflow, wherein one portion of the airflow flows through the fins and another portion of the airflow flows through the slot and blows over other electronic components near to the GPU. Thus, rebounding of the airflow is reduced, and the heat dissipating device has better heat dissipating efficiency.
