Abstract
A heat sink (10) includes a circular base (20), a plurality of fins (30), and a central post (40). The base is adapted to be in thermal contact with an electronic device, to remove heat therefrom. The post extends from a top surface (26) of the base. The post has a first surface connected to the top surface and a second surface (44) dimensioned according to a heat sink fan to be attached thereon. The post also has a concave side surface (42) between the second surface of the post and the top surface of the base, for directing airflow. The fins are identical in height to the post. The fins are curved, aligned and spaced from each other at uniform intervals corresponding to directions of airflow generated from the fan. These minimize resistance to cooling air entering or exiting the heat sink.
