Abstract
The invention relates to an electric fan, in particular, for motor vehicles, comprising an electric drive motor, a fan wheel coupled with the drive motor, and an electronic control unit for controlling the motor. In order to make the electric fan structurally more simple and more cost-effective to assemble, it is proposed that the drive motor and the control unit be arranged in a common housing, and that the housing have air vents for passage of a flow of cooling air generatable by the fan wheel, and a heat sink of the control unit be arranged at at least one air vent.
