Abstract
A heat dissipation apparatus (10) includes a centrifugal blower (12) and a fin assembly (11) having a plurality of fins (111) disposed at an air outlet (129) of the centrifugal blower. The centrifugal blower includes a first tongue (130) distant from the fin assembly, and a second tongue (131) located between the first tongue and the air outlet of the blower. The second tongue has an end (132) substantially parallel to the fins of the fin assembly to guide an airflow smoothly flowing through the fins.
