The function of the heater tank is to provide heating for the car, raise the temperature inside the car and remove the frost and fog on the window glass. Its working principle is that when the engine is working, the coolant heated by the engine cylinder at high temperature 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 out by the blower, so as to raise the temperature in the carriage and defrost.
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. The blower is composed of adjustable speed DC motor and squirrel cage fan. Its function is 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 of the car can be adjusted.
The car warm air blows the residual heat of the engine into the car through the blower. When the engine just started, because the engine did not produce enough temperature. In this case, it is not only impossible to turn on the warm air, but also increases the discharge capacity of the battery. (Photo/Text/Photo: Chen Miaoling) @20 19
