    摘要: A radiator fan module for a motor vehicle has a fan shroud with a fan impeller aperture and a motor support disposed within the fan impeller aperture, for an electric motor, and has a support-side housing part and has a plurality of struts that are connected to the fan shroud. A fan impeller is disposed in the fan impeller aperture and is driven in rotation about an axis of rotation. The fan impeller has a hub-side housing part and a plurality of radially outwardly directed radiator fan blades disposed on the hub-side housing part. The support-side housing part and the hub-side housing part have different diameters, wherein the support-side housing part or the hub-side housing part that has a greater diameter overlaps the other of the support-side housing part or the hub-side housing part, with an air gap being formed.

    摘要: An impeller includes a hub, an outer ring, a plurality of first blades and a plurality of second blades. The plurality of first blades are arranged around the hub at intervals. Each of the plurality of first blades passes through the outer ring, extends inward from the outer ring, and is connected to the hub. The plurality of second blades are arranged around the hub at intervals. Each of the plurality of second blades passes through the outer ring. At least one of the plurality of second blades is disposed between the plurality of first blades. A length of each of the plurality of second blades is between 10% and 45% of a length of each of the plurality of first blades.

    摘要: A ring fan and shroud assembly having a fan, a shroud member, a recirculating flow member, and a plurality of curved guide vanes. The fan has a hub with a plurality of projecting fan blades and an outer ring member. The shroud member is positioned around the outer ring member. The recirculating flow member is on the shroud member and is positioned forward adjacent the outer ring member. The guide vanes are positioned within the recirculating flow member and define an inlet angle, which is nearly tangential with an outer entry diameter radial surface of the recirculating flow member, and an outlet angle that is nearly radial along an inner exit diameter of the recirculating flow member.
