The heating system of a car can heat the air inside the car or suck the air inside the car from the outside, thus increasing the temperature inside the car. There are many kinds of automobile heating systems, which can be divided into hot water heating system, gas heating system and tail gas heating system according to different heat sources. At present, hot water heating system is mainly used for cars, and gas heating system is mainly used for large vehicles. ?

Working principle of automobile heating system;

When the engine is working, the coolant heated to high temperature by the combustion of the engine cylinder enters the heat exchanger through the water inlet pipe under the action of the water pump of the engine cooling system, and the heat emitted by the coolant is sent to the carriage or windshield by the air blown by the blower, so as to raise the temperature in the carriage and defrost. The cooling liquid radiated by the heat exchanger is pumped back by the water pump through the return pipe to realize warm air heating.
