The heat source of the heater is to use the waste heat of the engine cooling water and send it to the radiator of the heater through the water pipe.
As long as the engine does not stall, the cooling water keeps a "small cycle" with the radiator. It is in conjunction with the engine radiator.
Because the radiator of the heater has no thermostat, the heat source can be maintained uninterruptedly.
The driving device is powered by a DC motor, and the hot air is delivered to the car through a blower. At the same time, the hot air can also be delivered to the car.
