The utilization of double fans for engine cooling of motor vehicles is known. Said fans generate a flow of air which then serves to cool a heat exchanger, in particular a coolant radiator for motor vehicles. The double fan is herein characterized by an optimal use of the surface of the coolant radiator that is to be cooled, so as to be able to achieve a cooling performance as high as possible. The assembly of the double fan has up to now been such that a separate electric motor is provided for each blower. The double fan (1) for a heat exchanger (2), in particular a coolant radiator of a motor vehicle, has a first blower (4) and a second blower (5). According to the invention, the first driven blower (4) drives the second blower (5) by way of a transmission element (10) provided on the outer surface (11) of the first blower and an outer surface (12) of the second blower (5). The double fan is provided for a heat exchanger, in particular a coolant radiator of a motor vehicle. |
