ABSTRACT:
In a boiling liquid engine cooling system which employs an electric fan for increasing the condensation function of a radiator (or condenser), there is employed a control means which restrains the rotation speed of the electric fan to a low level at the beginning of the fan rotation and thereafter gradually increases the rotation speed to the normal level as the time proceeds. With this, undesirable sudden violent boiling of liquid coolant in the coolant jacket is prevented.
