Radiator is one of component in the engine cooling system. Radiator function is to transfer heat from the hot water coolant. The coolant flows from the radiator coolant inlet to the outlet through many tube assembled in a parallel arrangement. The heat transfer from many tube to the many fin and then transfer the heat to the air blown throught it by the fan. A radiator is a type of heat exchanger.
Most new model cars use aluminum radiators. These radiators are made by brazing thin aluminum fins to flattened aluminum tubes.
