Abstract
A centrifugal fan for a motor vehicle has a fan rotor driven in rotation by an electric motor and lodged in a central part of a casing. The outer walls of the casing define, in conjunction with a peripheral portion of the rotor, a volute for channeling air which is delivered by the rotor in a tangential direction. The outer wall of the casing includes a longitudinal side wall portion formed with through apertures constituting diversion ports, for taking off some of the air delivered by the rotor and diverting this air through an external duct fixed to the casing and open into the central region of the latter, so as to cool the motor.
