    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 heat sink includes a fin unit (10) and a heat pipe (40) for transferring heat from a heat-generating device to the fin unit. The fin unit includes a plurality of fins (20) parallel to each other. A flow channel (23) is defined between any of two neighboring fins for an airflow flowing therethrough. Each fin defines a through hole (25) having an axis of symmetry which extends along the flowing direction of the airflow. The through hole is for extension of the heat pipe therethrough. A plurality of protrusions (221, 222, 223, 224) extend outwardly from each fin. The protrusions being arranged irregularly around the heat pipe for guiding the airflow flowing to the heat pipe.

    摘要: A notebook computer (1000) includes a base (100), a cover (300), a computer printed circuit board (PCB) (200) and a centrifugal fan (40). The cover covers the base, and cooperates with the base to form a receiving space (500) therebetween. The computer PCB is received in the receiving space and mounted on the base. The centrifugal fan is received in the receiving space, and includes a stator (401) and an impeller (402), rotatable with respect to the stator. The stator includes a motor (415) and a fan PCB (405) directly attached to the base. The motor electrically connects to the fan PCB. When the impeller rotates, airflow enters the receiving space through top and bottom air inlets (304, 104). The fan PCB is integrally formed with the computer PCB and has a height less than the computer PCB.
