Product Description
Automobile water pipe return pipe is a pipe connecting the engine cooling system and the coolant return device, and its functions mainly include the following aspects:
1. Coolant reflux: The main function of the water pipe reflux pipe is to reflux the coolant from the engine cooling system to the coolant reflux device. When the engine is running, the coolant will absorb the heat generated by the engine and circulate through the cooling system to maintain the normal working temperature of the engine. The water return pipe returns the coolant from the engine cooling system to the coolant return device to keep the circulation and stability of the coolant.
2. Exhaust of cooling system: The water return pipe can also help the cooling system to remove air. In the cooling system, bubbles and air masses will be generated due to thermal expansion and cold contraction and coolant replacement. Through its position and design, the water return pipe can make bubbles and air masses in the cooling liquid float to the cooling liquid return device, thus realizing the exhaust of the cooling system.
3. Stability of cooling system: The existence of water return pipe can improve the stability of cooling system. It can help the circulation and flow of coolant and keep the stable working pressure and flow of cooling system. At the same time, by eliminating air and bubbles, the water return pipe can reduce the air resistance and air lock in the cooling system, and improve the cooling effect and heat dissipation performance.
4. Prevent coolant leakage: The connection and sealing design of water return pipe can prevent coolant leakage. It ensures that the coolant will not leak into the environment around the engine during the backflow process, and maintains the integrity and normal operation of the cooling system.
To sum up, the function of the automobile water pipe return pipe is to return the coolant, exhaust the cooling system, stabilize the cooling system and prevent the coolant from leaking. As an important part of the engine cooling system, the water return pipe has an important influence on the circulation and stability of coolant, engine heat dissipation and normal operation of the cooling system. Therefore, the design, manufacture and maintenance of water return pipe need to be strictly controlled to ensure the normal operation of cooling system and the driving safety of vehicles.
