摘要： A centrifugal fan includes a fan frame (20), and a stator (30) and a rotor (40) received in the fan frame. The fan frame includes a bottom base (22), an opposite top cover (21) and a side wall (23) interconnecting the bottom base and the top cover. A first air inlet (24a) is defined in the top cover and a second air inlet (24b) is defined in the bottom base. The rotor includes a hub (41) and a plurality of blades (42) extending from an outer periphery of the hub. An air flow channel (48) is formed between an outer periphery of the blades and the side wall of the fan frame. A cylindrical wall (26, 26a) is formed around one of the first air inlet and the second air inlet to guide airflow from the first and second air inlets into the air flow channel and block the airflow in the air flow channel from flowing back towards the first and second air inlets.

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.
