ABSTRACT:
A thermal control device (10) for cooling or heating the passenger compartment of parked vehicles or a vehicle seat cushion (140). The device consists of a door frame/window interfacing fixture (12) that is attached between a vehicle door frame (200) and the vehicle's side window (202). The fixture includes an air exhaust sleeve (20) into which is inserted an air exhaust port (44) located on a device housing (30). The housing (30) also includes an air outlet port (58) that vents into the passenger compartment and incorporates a d-c motor (68), a centrifugal fan (70), a voltage polarity switch (71) and a temperature control module (72) which consists of a first and second heat exchanger (74,82) and a Peltier-effect thermoelectric element (90). Electrical power is supplied by a device control unit (108) that is programmed to apply electrical power from the vehicle battery (206) at a pro-selected time. When power is applied, the motor (68) rotates the fan (70) which allows either cool air or warm air as selected by the switch (71), to pass through the heat exchangers (74,82). In the summer or when cool air is preferred, the warm air is directed to the outside of the vehicle through the air exhaust port (44) and the cool air is directed through the air outlet port (58) into the vehicle passenger compartment or the seat cushion (140). In the winter cold air is directed outside the vehicle and the warm air is directed into the passenger compartment.
