ABSTRACT:
A heat dissipation device includes a heat sink (50) and a fan (10) located above the heat sink for providing airflow. The heat sink includes a base (40) and a heat dissipating part (30) arranged on the base. The heat dissipating part includes a plurality of fins (31), each adjacent pair of the fins defines a channel (35) therebetween. The heat dissipating part defines a plurality of passages (34) disposed diagonally thereat and perpendicular to the channels. The channels and the passages are oriented consistently with the airflow of the fan.
