AXIAL FAN FOR A VEHICLE RADIATOR

摘要

The invention relates to an axial fan (10) for a vehicle radiator (11), the impeller (12) of which axial fan (10), which delivers the main air flow (H), is driven by a hub motor (13) which is centrally rotationally coupled to said impeller (12), wherein the vehicle radiator (11) is arranged on the suction side (p^-) of the impeller (12) and a fan frame (19) which surrounds the hub motor (13) is arranged between the vehicle radiator (11) and the impeller (12), wherein the impeller (12) is formed from a number of radially arranged blades (12.1) which are surrounded by an outer ring (12.3) which encircles the radial outer ends of the blades (12.1). According to the invention, a separate air guiding device (inlet ring 20) is provided at least on the suction side of the outer ring (12.3), over which air guiding device an air flow (LR) which flows back from the pressure side (p⁺) to the suction side (p^-) can be deflected and fed to the main air flow (H).
