Abstract
A system that supplements the cooling of the power train of the vehicle and maintains the vehicle's cabin temperature. The system includes an processor, a blower, a heater core, and an evaporator. The blower blows air over the heater core so as to make the heater core in essence an auxiliary radiator. The system further includes a first proportioning valve and a second proportioning valve. The proportioning valves are operable by the processor to control the flow of the dissipated heat between the vehicle cabin and a designated location. Specifically, the first proportioning valve is disposed upstream the heater core and is moveable between an open position and a closed position. The second proportioning valve is disposed downstream the heater core and directs airflow from the heater core between the vehicle cabin and the environment.
