The car radiator is mainly composed of three parts: the water inlet chamber, the water outlet chamber and the radiator core. The coolant flows in the radiator core and the air passes outside the radiator. The hot coolant cools due to heat dissipation from the air, and the cold air warms up by absorbing the heat dissipated by the coolant.
The development of materials and manufacturing technology for automotive radiators is very fast. In the operation, aluminum radiators have obvious advantages in material weight reduction, and gradually replace copper radiators in the field of cars and light vehicles, copper radiators. Manufacturing technology and technology have made great strides, and copper brazed radiators have obvious advantages in engine radiators such as passenger cars, construction machinery, and heavy trucks.
Car radiators are mainly considered from the perspective of environmental protection (especially in Europe and America). Among the new European cars, aluminum radiators account for an average of 64%. From the development prospect of China's automobile radiator production, the aluminum radiator produced by brazing is gradually increasing. Brazed copper radiators are also used in buses, trucks and other engineering equipment.
