  • Heater/defroster for an automobile
    Patent number: 6691925
    Abstract: Apparatus and Method for accelerating the warm-up of a heater/defroster in a passenger compartment of an automotive vehicle. A working fluid, such as power steering oil is rapidly heated by pumping it through a small orifice. An oil-to-coolant heat exchanger transfers heat from the working fluid to a liquid coolant. A blower generates an air stream and directs it across heat exchange surfaces of a coolant-to-air heat exchanger. Meanwhile the heated coolant is circulating through the interior of the coolant-to-air heat exchanger. This transfers heat from the liquid coolant and warms the air stream.
    Type: Grant
