What is the function of the car heater tank? Where does the warm air in the car come from? Be specific. Thank you!
Principle: When the engine is working, the coolant heated to high temperature by 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 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 a speed-adjustable DC motor and a squirrel-cage fan, and its function is to blow cold air to the heater, and then 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.
Extended data:
Matters needing attention in the use of automobile warm air:
1, don't get in the car and turn on the heater.
The car warm air blows the residual heat of the engine into the car through the blower. When the engine was just started, the engine did not generate 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.
2. Don't turn on the heater when idling.
When the car is idling, the fuel of the engine is not fully burned. It may not only increase the carbon deposition of automobile engines, but also produce too much carbon monoxide. This can easily lead to carbon monoxide mixed in warm air entering the car.
Don't turn on the air conditioner key.
When the car heater is turned on, the air conditioning key of the car is turned on. In this case, it not only increases the fuel consumption of the car, but also has no effect.
