What is the car water tank pipe
automobile water tank pipe is an important part of automobile cooling system, its main function is to heat the engine. The water tank pipe includes the upper water pipe and the lower water pipe, which form a coolant circulation system by connecting the engine and the water tank to ensure that the engine can maintain normal temperature under various working conditions.
Structure and function of water tank pipe
upper water pipe : one end is connected to the upper water chamber of the water tank, and the other end is connected to the outlet of the engine water channel pump. After the coolant flows out of the engine, it enters the water tank through the upper pipe to dissipate heat .
sewer pipe : one end is connected to the sewer chamber of the water tank, and the other end is connected to the intake of the engine water channel. After cooling in the water tank, the coolant flows back to the engine through the downpipe to form a cycle .
The working principle of the water tank pipe
After the coolant absorbs heat inside the engine, it flows into the water tank through the upper water pipe for heat dissipation, and then returns to the engine through the lower water pipe to form a closed-loop cooling system. This cycle can ensure that the engine can maintain a normal temperature under various working conditions, while reducing the impact on the water pump, so that the temperature above and below the radiator is more uniform .
Water tank pipe maintenance and common problems
Regularly check the temperature of the upper and lower pipes of the tank : the temperature of the upper pipe is usually higher, close to the operating temperature of the engine, generally between 80°C and 100°C. If the upper water pipe temperature is too low, it may indicate that the engine has not reached the operating temperature or there is a fault in the cooling system .
winter maintenance : in winter, pay attention to the maintenance of the cooling system, the use of high-quality antifreeze to prevent icing, rust and scale, and regularly clean the cooling system to prevent rust and scale limit the flow of antifreeze, reduce the heat dissipation effect .
The main role of the car water tank pipe includes the following aspects :
Coolant circulation : The tank pipe plays a key role in the cooling system. The coolant enters the engine from the lower water pipe of the water tank through the pump for cooling, and then returns from the engine to the water tank through the upper water pipe, forming a cycle mode of entering and exiting the bottom. This design is based on the principle of hot water rising, so that the upper part of the radiator temperature is higher, the lower part temperature is lower, not only can improve the heat dissipation efficiency, but also reduce the impact on the pump .
Pressure regulation : The water tank pipe also includes some hoses, which can effectively release pressure at high temperature to ensure the normal operation of the system. For example, the hose next to the filling kettle can be vented to ensure the smooth discharge of gas in the waterway; The hose above the water tank is mainly used to relieve pressure and prevent the system pressure from being too high .
System maintenance : The design and maintenance of tank pipes is critical to the stable operation of the cooling system. The coolant should be replaced regularly, and the water tank should be cleaned before adding the new coolant to ensure its anti-corrosion, anti-boiling, anti-scale and other effects, to protect the engine cooling system from damage .
