ABSTRACT:
A cooling fan includes a fan housing, a rotor and a stator. The fan housing forms an air inlet and an air outlet at two opposite sides thereof, respectively. A base is received in the fan housing and arranged at the air outlet of the fan housing. A guiding wall extends upwardly from an outer periphery of the base. An outer diameter of the guiding wall decreases along a direction from the air inlet to the air outlet. A plurality of stationary blades extend from an outer surface of the guiding wall to the fan housing. The stator is arranged in the housing and mounted on the base, and the rotor is rotatably supported by the stator.
