What is the automobile cooling system made of?

Engine cooling system can be divided into two categories: water cooling and air cooling. At present, forced circulating water cooling system is widely used in automobile engines. The water cooling system is mainly composed of water pump, radiator, thermostat, fan, fan control mechanism, shutter, water jacket, compensation water tank, coolant thermometer and coolant temperature alarm device.

The function of the cooling system is to dissipate some heat absorbed by the heated parts of the engine in time, so as to cool the engine and keep it working at normal temperature. Cooling medium is generally divided into air cooling system and water cooling system. With the increasing power of automobile engines, the requirements for heat dissipation are getting higher and higher. Because it is difficult for air-cooled system to achieve uniform cooling effect, it is easy to cause some parts to overheat and damage the engine, and the cooling efficiency is not as good as that of water-cooled system, so almost all cars now adopt water-cooled cooling system.

The function of the cooling system is to ensure that the engine works at the most suitable temperature under all working conditions. Whether the cooling system is matched and properly set will directly affect the power performance, service life and fuel economy of the engine. So the cooling system plays an important role in the engine.
