Abstract
A fan for a motor vehicle includes an impeller formed by multiple blades () extending radially from a hub (), and a base supporting the impeller. The impeller is rotated about an axis of rotation by an actuator means and is positioned inside a hollow cylindrical cavity having the same axis and formed by an axial wall () attached to the base. The base includes an upstream front wall () extending externally in a radial plane with reference to the axis, and an outer wall () extending axially from the front wall (). The front wall () has a protrusion () bordering the impeller, with the protrusion extending axially upstream with respect to the plane of the front wall (). The upstream end of the protrusion is situated further upstream than the upstream end of the blades () of the impeller.
