Engine produces high amount of heat while running. This may increase the engine temperature to such a level where, it can damage the engine components if temperature is not controlled. Radiator plays an important role in engine cooling system. Radiators are heat exchangers used to transfer thermal energy from one medium to another for the purpose of heating and cooling. As there is transfer of energy from one medium to another, some amount of energy is lost. Due to limited resources, economic factors and various other restrictions, there is sometimes a compromise between either the efficiency of the radiator or the various above mentioned factors.
