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

A cooling device for cooling an electrically driven or driveable motor vehicle, having a first heat exchanger and a second heat exchanger, having an air-guiding channel which connects the first heat exchanger and the second heat exchanger and which has two diametrically oppositely situated passage openings which are reversibly closable by means of a first air guide and by means of a second air guide, and having a cooler fan which is arranged downstream of the second heat exchanger in terms of flow.

Cooling device for a motor vehicle

A fan assembly including a first cooling fan arranged with respect to an air flow direction downstream of a heat exchanger and a second cooling fan. The first cooling fan is a radial fan that draws cooling air axially and expels the cooling air radially and the second cooling fan is an axial fan that draws cooling air axially and expels the cooling air axially. The axial fan is arranged downstream of the heat exchanger and laterally adjacent to the radial fan in a plane parallel to the rear side of the heat exchanger in a plane parallel to the front side of the heat exchanger.

Fan assembly for a motor vehicle

The present invention relates to a fan frame for a plurality of fan modules, particularly for a radiator of a motor vehicle, comprising a first fan holder having a first outflow region, at least one further fan holder having a further outflow region, and an intermediate region that connects adjoining edge regions of the first and the further fan holders to each other. The fan frame is characterised in that a shielding device, which separates the first and a further outflow region from each other, is provided in the intermediate region. The present invention further relates to a fan module, particularly having such a fan frame.

Fan frame and fan module

A ventilation device has a holder, in particular a ventilation frame, with a substantially circular continuous opening for receiving a ventilation wheel rotating about the central axis, thereof. The opening is bordered by an edge face running substantially cylinder-symmetrically about the central axis. As the edge face in two separate, diametrically opposed peripheral sections the radius is at least partly enlarged in comparison to the cylinder-symmetrical form in the remaining peripheral sections, and/or a circular projection of she edge face, which projection projects radially inwards, is axially offset away from a space provided for the ventilation wheel. Because of she corresponding shaping of the edge face of the opening, contact and/or development of noise between the ventilation wheel and the edge of the opening is prevented in the ventilation frame in the event of a yawing of the ventilation wheel.

Ventilation device and vehicle with a ventilation device

The invention relates to a cooling fan module for a motor vehicle, having a fan impeller which has a multiplicity of fan impeller blades which are connected to one another via a fan impeller outer ring, having a frame, on which the fan impeller is mounted, having an annular reverse flow guide device, which has an inner ring and an outer ring and which is designed to de-spin a reverse flow between the inner ring and the outer ring and to mix said reverse flow with the slot flow between inner ring and fan impeller outer ring.
