Seat heating system for air-cooled IC engine vehicle - uses cooling air to heat finned heat exchanger having electrically driven fan blowing fresh air through fins

摘要

The engine is surrounded by a cover, and a pipe draws the cooling air from under the cover. The pipe passes through an enclosure which it shares with the engine exhaust, gaining extra heat. A control vane regulates the air flow to a tubular heat exchanger with fins along the tubes. An electric motor driven cylindrical fan blows fresh air across the heat exchanger to heat the interior space. A battery powered Peltier effect device may be placed near the fan to cool the interi interior space. The heat tube is wound around the electric motor. The radiator has a fluid flow circuit of which a part is situated within the back rest of the driver's seat.
