    摘要: A heat dissipation apparatus (10) includes a heat-dissipating fan (14) and a fin assembly (12). The heat-dissipating fan includes a casing (141) and a plurality of blades (142) rotatably received in the casing. The casing defines an air outlet (148) through which an airflow generated by the blades flows. The fin assembly is disposed at the air outlet of the fan, and includes a plurality of first fins (121) and a plurality of second fins (122) disposed between the first fins and the blades of the fan. The second fins are so positioned that outer ends of the second fins are oriented toward a far side of the air outlet while inner ends of the second fins are oriented toward a near side of the air outlet. The outer ends of the second fins are located adjacent to the first fins. An airflow generated by the blades first flows to the near side and then to the far side of the air outlet.
