  • Cooling system for hybrid power system
    Patent number: 7377237
    Abstract: A cooling system for a hybrid power system that includes an engine employs an engine cooling circuit to deliver coolant to the engine, the engine cooling circuit including a radiator and a main fan to draw air through the radiator. When the hybrid power system further includes an inverter, then the inverter is cooled via an inverter cooling circuit that is formulated as one portion of the cooling system to deliver coolant to the inverter, the inverter cooling circuit including a heat exchanger located such that the main fan draws air through the heat exchanger when the main fan is active. The cooling system also includes a secondary fan to selectively draw air though the heat exchanger during operation of an inverter cooling circuit coolant pump.
    Type: Grant

  • Method of cooling a hybrid power system
    Publication number: 20080060370
    Abstract: A method of controlling a cooling system is provided for a hybrid power system that includes an engine that employs an engine cooling circuit to deliver coolant to the engine, the engine cooling circuit including a radiator and a main fan to draw air through the radiator. When the hybrid power system further includes an inverter, then the inverter is cooled via an inverter cooling circuit that is formulated as one portion of the cooling system to deliver coolant to the inverter, the inverter cooling circuit including a heat exchanger located such that the main fan draws air through the heat exchanger when the main fan is active. The cooling system also includes a secondary fan to selectively draw air though the heat exchanger during operation of an inverter cooling circuit coolant pump.
