ABSTRACT:
A cooling fan includes a fan housing, a base, a rotor, a stator, and a fan guard. The fan housing forms an intake and an outlet at two opposite sides thereof, respectively. The base is arranged at the outlet of the fan housing. The stator is mounted on the base. The rotor is rotatably supported by the stator. A plurality of stationary blades extends from the base to the fan housing. The fan guard attaches to the outlet of the fan housing. A cylinder is arranged at a center of the fan guard and attaches to the base of the fan housing. A plurality of guard blades extend radially and outwardly from the cylinder. Each guard blade and the nearest stationary blade define a gap therebetween along a circumference of the cooling fan.
