  • Reverse fan operation for vehicle cooling system
    Patent number: 7066114
    Abstract: A system for reducing the time that it takes a vehicle fuel cell engine to reach its operating temperature at vehicle start-up. The system includes a radiator and a fan, where a cooling fluid from the engine is directed through the radiator where it is cooled by airflow from the fan during high load conditions. The radiator also receives ambient air through a front grill from movement of the vehicle. During vehicle start-up, when the engine is below its optimal operating temperature, the fan is operated in a reverse direction at variable speeds depending on the speed of the vehicle, so that the airflow through the grill that may otherwise convectively cool the engine is significantly reduced or eliminated.
    Type: Grant
