Abstract
A radiator blower, in particular for motor vehicles, is indicated that comprises a plurality of individual fans (), each having an electrical drive motor (), and a plurality of switches (S, S, S), each capable of being switched over into two positions, by means of which the drive motors () are capable of being turned on and back off individually or in a series or parallel connection. To prevent disturbing noises from developing when the individual fan () comes to rest after being turned off, when the operating drive motor or motors () is/are turned off, an electronic control unit () forces the switches (S, S, S)—at least temporarily—over into switch positions that bring about a short-circuiting of the turned-off drive motor or motors (FIG.).
