Patent number: 8230910Abstract: An apparatus for conveying a cooling air flow for at least one motor vehicle heat exchanger has a fan frame, a fan wheel, a fan control unit, and a cooling body. The fan frame has a frame opening, which the fan wheel rotates within. The fan control unit is arranged in an edge region of the frame opening. The cooling body cools the fan control unit and has cooling domes. A first cooling dome is arranged entirely radially exterior to the frame opening and a second cooling dome is located partially radially within the frame opening and partially radially exterior to the frame opening. The first cooling dome exchanges heat with an auxiliary flow that flows radially exterior to the frame opening with respect to the center of the fan wheel when the fan wheel rotates.Type: GrantFiled: October 4, 2006Date of Patent: July 31, 2012Assignee: Behr GmbH & Co. KGInventors: Thomas Bielesch, Benjamin Schweizer, Michael Spieth, Ulrich Vollert

Publication number: 20090130968Abstract: The invention relates to a device for influencing or regulating an air flow for a motor vehicle, the device comprising a flexible film element (8) provided with a plurality of openings for the passage of an air flow, and a rigid carrying element (9) on which the film element (8) is held, the film element (8) comprising a plurality of flap elements (7) which correspond to the openings and are defined by a flap edge (7a) which penetrates the film element (8) and only partially surrounds the flap element (7). The aim of the invention is to produce a device for regulating an air flow for a motor vehicle that can be economically produced and has a high durability with a low susceptibility to dirt accumulation. To this end, the carrying element (9) has flat regions (9a) and openings, the openings being associated with the flap elements (7) for the passage of the air flow. The film element (8) is arranged on the flat regions (9a).Type: ApplicationFiled: January 16, 2006Publication date: May 21, 2009Inventors: Martin Harich, Georg Kaemmler, Ulrich Vollert
