Use of heating water pipes
The warm air pipe is the pipe connecting the water tank circulation system and the heater. Its function is: the engine starts, and the water temperature rises slowly for a large cycle. At the thermostat, the heating water pipe is directly connected to the small water tank of the heater.
The small water tank has temperature, and then the temperature can be emitted by the fan. The temperature is controlled by sensors, and there are very luxurious cars. There are also electric heating measures, which can be heated without water temperature.
The warm water pipe is a pipe that brings the heat of the engine to the car through the "water" in the car water tank to keep the car warm. Usually one in and one out. If it is not installed correctly, it may make the water flow too smooth and will not have much impact.
If it is broken, it will cause the coolant of the car to leak, the engine will not dissipate heat well or can not, and the water temperature will rise, which will do great harm to the car.
The heater hose is connected to the heater tank in the instrument panel. Closing the warm water circulation can reduce the temperature in the cab in summer. The former is generally designed under the front bumper of the automobile, while the latter is generally designed on the heater or the pipeline nearby.
