Automobile heating system is a complete set of devices that blow cold air to the surface of heat exchanger, absorb its heat and introduce it into the car, thus increasing the temperature inside the car.
Water heating system; The heat source comes from the engine coolant, and the water heating system is mostly used in cars, trucks and buses with low heating requirements. Water heating and warm air system is mainly composed of heater, hot water regulating valve, blower and control panel.
Among them, the blower is composed of adjustable speed DC motor and squirrel cage fan, which is used to blow cold air to the heater, and the cold air is heated and sent into the car. By adjusting the speed of the motor, the air supply to the compartment can be adjusted.
Warm air heating system; The heat source comes from the engine exhaust system. Air-cooled heating system is mostly used in air-cooled engine cars.
Heat exchanger type heating system; The hot air in the exhaust pipe is introduced into the heat exchanger 5, and the cold air blown by the blower absorbs heat through the heat exchanger, and then is introduced into the car for heating or defrosting.
Heat pipe heating system; The heat pipe heat exchanger is vertically installed in the floor of the carriage, the condensation and heat release section is above the floor, and the waste gas heating section is below the floor. The exhaust gas discharged from the exhaust pipe of the automobile engine is introduced into the heat pipe heat exchanger, and the heat pipe heat exchanger is filled with liquid ammonia. After being heated, liquid ammonia vaporizes, rises to the upper part of the heat pipe heat exchanger, exchanges heat with air, and heats the air entering from the vent.
After the air is heated, it is blown into the carriage by the blower for heating, and the released ammonia condenses and flows back to the lower part, and then the next working cycle is completed.
Fuel air heating system; A heating system that directly heats air with fuel is called a fuel-air heating system.
Independent combustion heating system; The heat source comes from the heat generated by the combustion of special fuel. Independent combustion heating system is mainly used for buses.
Fully preheat the warm air system; The heat source comes from the heat of engine coolant and the heat of special fuel combustion device. Comprehensive preheating and heating system is mostly used in buses.
