In order to avoid overheating of the engine, the parts around the combustion chamber (cylinder liner, cylinder head, valve, etc.) must be properly cooled. There are three types of cooling devices for internal combustion engines, water cooling, oil cooling and air cooling. The automobile engine cooling device is mainly water-cooled. It uses the circulating water in the cylinder water channel to cool, and introduces the heated water in the water channel into the radiator (water tank), and then returns to the water channel after being cooled by the wind. In order to ensure the cooling effect, the automobile cooling system generally consists of a radiator (1), a thermostat (2), a water pump (3), a cylinder water channel (4), a cylinder head water channel (5), and a fan.

1. When the temperature of the air flowing through the radiator rises, the bimetallic temperature sensor is heated and deformed, forcing the valve shaft to rotate and opening the oil inlet hole on the driven plate. The silicone oil stored between the driven plate and the front cover flows into the working cavity between the driving plate and the driven plate, the clutch is engaged, and the fan speed increases. The higher the air temperature, the larger the opening of the oil inlet hole, and the faster the fan speed.

2. When the temperature of the air flowing through the radiator drops, the bimetallic temperature sensor returns to its original state, and the valve plate closes the oil inlet. Under the action of centrifugal force, the silicone oil returns from the working cavity to the oil storage cavity through the oil return hole, and the clutch is separated. The fan speed becomes very low.
