What is the function of car radiator

The main job of the cooling system is to dissipate heat into the air to keep the engine from overheating, but the cooling system has other important roles as well.

To avoid overheating of the engine, the components surrounding the combustion chamber (cylinder liners, heads, valves, etc.) must be properly cooled. In order to ensure the cooling effect, the automobile cooling system is generally composed of a radiator, a thermostat, a water pump, a cylinder water channel, a cylinder head water channel, and a fan. The radiator is responsible for the cooling of circulating water. Its water pipes and heat sinks are mostly made of aluminum. The aluminum water pipes are made into a flat shape, and the heat sinks are corrugated. Pay attention to heat dissipation performance. The installation direction is perpendicular to the direction of air flow. The wind resistance should be small and the cooling efficiency should be high. The coolant flows inside the radiator core and the air passes outside the radiator core. The hot coolant cools by dissipating heat to the air, and the cold air heats up by absorbing the heat given off by the coolant, so the radiator is a heat exchanger.

Automobile radiators are generally divided into water cooling and air cooling. The heat dissipation of an air-cooled engine relies on the circulation of air to take away heat to achieve the effect of heat dissipation. The outside of the cylinder block of the air-cooled engine is designed and manufactured into a dense sheet-like structure, thereby increasing the heat dissipation area to meet the heat dissipation requirements of the engine. Compared with the most used water-cooled engines, air-cooled engines have the advantages of light weight and easy maintenance.
