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.

摘要： A centrifugal fan includes a fan frame (20) and a fan impeller (10) received in the fan frame. The fan impeller includes a hub (12) and a plurality of fan blades (14) extending radially from an outer periphery of the hub. Each of the fan blades has a leeward lateral surface (144a) and an opposite windward lateral surface (144b) as the fan impeller rotates. At least one of the fan blades has a rib (146) protruding longitudinally and outwardly from the leeward lateral surface of the fan blade. The rib is located adjacent to an outmost free end of the fan blade and adapted for blocking an airflow generated by the fan impeller to flow back towards the fan blades of the fan impeller.
