Abstract
A heat removal system includes a heat dissipation assembly (10) and a system fan (20) which cooperatively achieve optimized heat dissipation efficiency. The heat dissipation assembly includes a heat sink (12) and an angled fan (14). The heat sink includes a base (122) and a plurality of parallel fins (124). A slanted surface (126) is defined by a set of adjacent edges of the fins. The fan defines a through hole (142) at each of four corners thereof. Four screws (144) extend through the through holes, thus attaching the fan to the heat sink at the slanted surface. A rotational axis of the fan intersects a central portion of the base of the heat sink, which portion defines a region of highest temperature of the heat sink. The angled fan together with the system fan provide maximized cooling airflow.
