    摘要: An electronic assembly (1) includes a top cover (21), a bottom cover (22) and a thermal module (10). The thermal module includes a centrifugal blower (14) and a fin assembly (12). The blower includes a top lid (142) defining a first air inlet (146) therein, a bottom plate (147) defining a second air inlet (150) therein, and a sidewall (148). An air outlet (149) is defined in the blower in front of the sidewall. A first distance (H1) formed between the top cover and the top lid is greater than a second distance (H2) formed between the bottom cover and the bottom plate. A left edge (154) of the second air inlet adjacent to the air outlet offsets a distance from a corresponding left edge (155) of the first air inlet inwardly toward a rotation axis (A) of an impeller (143) of the blower.

    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.

    摘要: A cooling fan (20) includes a housing (22) and an impeller (24). The housing has a base (221), a sidewall (222) extending from a periphery of the base with an air outlet (226) defined therein, and a cap (223) covering the sidewall. The impeller has a plurality of blades (242) rotatably received in the housing for generating an airflow. An air channel (225) is formed between tip portions of the blades and an inner face of the sidewall. The air outlet has a near section (226A) and a far section (226C). The airflow first reaches the near section and then the far section. The base of the housing has a protrusion (227) extending into the air outlet for guiding the airflow flowing towards the far section from the near section of the air outlet.
