The main components of the water cooling system include: radiator, tube type, tube belt type, water pump, fan, wind and rain clutch and temperature control switch, fan clutch, fan temperature control switch, etc.

The forced circulation water cooling system is commonly used on automobile engines. It uses a water pump to increase the pressure of the cooling water and make it circulate in the engine cooling system. In the water-cooled engine, both the cylinder head and the cylinder block are cast with interconnected water pumps. Under the action of the water pump, the cooling water flows through the cooling jacket of the cylinder block and cylinder raft to absorb heat, and then flows into the radiator along the water pipe. Using the speed of the car and the strong suction of the fan, the air flow is high from front to back Through the radiator, the heat of the high-temperature cooling water flowing through the radiator is continuously dissipated into the air to lower the temperature of the cooling water. After the flushed water flows to the bottom of the radiator, the amount of water that is pushed into the engine again by the water pump is small. In this way, the large amount of heat generated by the engine during operation is constantly taken to ensure the normal operation of the engine. In order to reduce the heat at low temperatures Loss, shorten the warm-up time, speed up heat dissipation at low speed, the cooling system is equipped with a temperature-adjusting device; in order to enable the driver to keep abreast of the working condition of the cooling system, a water temperature meter and high-temperature warning lamp are also provided.
