Radiators - Automotive
Radiators are constructed to be used in automobiles, buildings and electronics. Radiators are heat exchangers which transfer thermal energy from one medium to another for purposes of cooling and heating. Most cars use aluminum radiators, made by brazing thin aluminum fins to flattened aluminum tubes. The coolant flows from the inlet to the outlet through many tubes mounted in a parallel arrangement. The fins conduct the heat from the tubes and transfer it to the air flowing through the radiator. Radiators are often behind the grille at the front end of a vehicle to save fan power consumption in vehicles. Radiators help avoid overheating and seizure in vehicles.
