ABSTRACT:
An electric cooling fan arrangement having a detachable resistor connected therewith for operating the cooling fan at a decreased rotational speed during periods of decreased cooling air requirement. This is especially desirable for removing the accumulated or built-up heat after the internal combustion engine of a motor vehicle has been switched off. The noise emission of the vehicle is thereby substantially lowered, while at the same time by using the rear window heater as drop resistor, a simple and economical realization of the electric cooling fan is developed.
