Abstract
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.
