The cooling system can be divided into air cooling and water cooling according to different cooling media. If the heat of the high-temperature parts in the engine is directly dissipated into the atmosphere for cooling, the device is called an air-cooled system. The device that transfers this heat to the cooling water and then disperses it into the atmosphere for cooling is called a water cooling system. Because the water cooling system has uniform cooling, good effect, and low engine running noise, the water cooling system is widely used in automobile engines at present.
