Publication number: 20210254634Abstract: A fan comprising a fan wheel with impeller hub and impeller blades, and electric motor with a stator and rotor that can rotate about rotation axis (RA) and has a rotor bell comprising an axially front-side rotor bell base. Impeller hub is fastened to the rotor bell wherein, in the rotor bell base, at least one aperture ensures a cooling air flow from the rotor bell. Fan comprises a cover plate arranged on the rotor bell base with a central opening, wherein cover plate covers at least one aperture of the rotor bell base axially spaced at least in sections, so that between the rotor bell base and an inner surface of the cover plate a radially inward extending flow channel toward the central opening of the cover plate is formed. The cover plate radially outward comprises an inclined or curved course in the direction of the rotor bell base.Type: ApplicationFiled: February 2, 2021Publication date: August 19, 2021Inventors: Roland KEBER, Tobias SIEGER, Wolfgang LAUFER, Clemens GUENTER
