Abstract

A fan assembly for cooling a radiator, a radiator-condenser assembly, or a radiator-condenser-intercooler assembly of a vehicle, comprising:
- a casing (12), having a through opening (14) and a support (16) , which is located at the centre of said opening (14);
- a motor-fan assembly (20) carried by said support (16), which includes an axial fan (22) rotatable with respect to said support (16) about an axis of rotation (X); and
- a toothed ring (34), which is fixed with respect to the casing (12) and surrounds said fan (22) said toothed ring (34) having a plurality of teeth (36) that follow one another in a circumferential direction,
wherein said toothed ring (34) has a front surface (38) sharing the axis of rotation (X) and a side wall (40) that forms sides of said teeth (36), where the distance in a direction parallel to the axis of rotation (X) between said side wall (40) and a plane orthogonal to the axis of rotation (X) varies periodically in a circumferential direction.
