ABSTRACT:
A cooling system for an internal combustion engine mounted within a vehicle includes a radiator for rejecting heat to ambient air and an axial fan mounted within a fan shroud associated with a radiator. The fan has a stationary hub equipped with louvers which may be controlled so as to either block off or allow airflow through the hub, and consequentially through the radiator. In this manner, the airflow past the fan may be greatly increased when the vehicle is operated at a higher groundspeed, while decreasing the amount of power consumed by the fan.
