What is the top pipe of the car water tank
The pipe at the top of the car water tank is the intake pipe , also known as the upper water pipe, which is mainly responsible for introducing the coolant from the engine to the water tank to help the engine heat . The pipe under the water tank is the outlet pipe or return pipe, which sends the cooling liquid back to the engine for cooling .
The cooling system of the car water tank works as follows: the high-temperature antifreeze enters the water tank from the engine through the upper water pipe, the coolant dissipates heat in the water tank through a dense fin, and then flows back to the engine through the lower water pipe (return water pipe) to form a cycle. In this process, the thermostat controls the circulation mode of the coolant to ensure that the coolant enters the water tank for large circulation heat dissipation .
In order to ensure the normal operation of the car water tank, it is necessary to check and maintain the cooling system regularly. During winter maintenance, high-quality antifreeze should be added to the tank, and the cooling system should be cleaned to prevent rust and scale from affecting the cooling effect . In addition, the water pipe should also be checked for stiffness or cracking to ensure that the pump is working properly .
The pipe at the top of the car water tank has two main functions :
The water inlet pipe : The water inlet pipe is one of the important pipes connecting the water tank and the engine cooling system. Its main function is to introduce the flowing coolant into the engine, reduce the engine temperature, and ensure the normal operation of the engine. The water inlet pipe is usually located in the upper part of the tank, through which the coolant is injected into the engine .
Return pipe : The function of the return pipe is to transfer the coolant flowing in the engine back to the water tank to complete the circulation of the coolant. The return pipe is generally located in the lower part of the water tank, connecting the engine and the water tank to ensure that the coolant can circulate in the system, so as to maintain the normal working temperature of the engine .
In addition, the top of the tank may also be equipped with hoses for exhaust and pressure relief. The main function of the hose located near the filling kettle is to exhaust the water to ensure that the gas in the water can be smoothly discharged to the atmosphere; The hose located above the water tank is mainly used for pressure relief. When the water temperature rises, it can effectively release the pressure to ensure the normal operation of the system .
