Abstract
A heat dissipation apparatus includes a heat sink configured to contact a heat source, and a fan mounted to the heat sink. The heat sink includes a base with a bottom surface for contacting the heat source, and a plurality of radial fins angling upwardly from a top surface of the base to form a truncated conical space in the middle of the heat sink. A cross section area of the truncated conical space gradually increases from the top surface of the base to top of the fins.
