A cooling fan has a fan shroud with a fan wheel recess surrounded by a shroud ring and a fan wheel rotatably mounted in the fan wheel recess for conveying the air flow along a conveying direction from a shroud upper side to a shroud underside. The fan wheel has a central hub cup with radially orientated blades and an outer ring connecting the blades at the blade tip ends. A circumferential ring gap is formed between the outer ring and the shroud ring. A rib structure in the ring gap reduces swirl in a gap flow orientated against the conveying direction. A shroud ring section of the shroud ring extends axially beyond the outer ring on the shroud underside. The shroud ring section is orientated parallel or at an angle of inclination and radially inwards relative to the conveying direction.

Cooling fan and cooling fan module

An electric-motor radiator fan of a motor vehicle has a fan shroud with a motor holder. An electric motor is inserted in the motor holder. A heat shield plate is arranged on the end side of the electric motor. The heat shield plate is placed onto a projection of the motor holder by way of a cut-out, and the heat shield plate is pivoted around the projection, which forms an axis of rotation, in such a way that the heat shield plate is forced at least in sections into at least one holding contour of the motor holder in a positive locking and/or friction-locking manner.
