Control unit for radiator fan has engine compartment flushing device that flushes compartment by activating radiator fan if temperature detected as is high enough to require it

摘要

The device has an engine compartment temperature determination device that defines a temperature state as high that requires flushing of the engine compartment if the temperature in the compartment equals or exceeds a defined threshold with the speed below a threshold or for the vehicle at rest. An engine compartment flushing device flushes the compartment by activating the radiator fan (22a,22b) if the temperature is high enough to require it. Independent claims are also included for the following: a method of controlling a radiator fan.
