Automotive radiator materials and manufacturing technology have developed rapidly. With its apparent advantages in the lightweight materials in the aluminum heat sink, the copper radiator manufacturing technology and process have been extensively developed while gradually replacing the copper radiator in cars and light vehicles. Construction machinery, heavy trucks, and other engine radiators have apparent advantages. Most radiators supporting foreign cars’ radiators are aluminum heat sinks, mainly considering environmental protection (predominantly in European and American countries). Among the new European cars, the percentage of aluminum heat sink is 64%. Judging from the development prospects of the production of auto radiators in my country, the number of aluminum radiators produced by complex sturgeon welding has gradually increased. Hard-welded copper radiators are also used for buses, cargo car cargo, and other engineering equipment.
