Radiator (heating) - Wikipedia

WebThe radiator is a heat exchanger meant to transfer heat from the coolant through its passages so that the coolant can continue traveling through the engine. Mainly made from aluminum, radiators transfer heat from the hot coolant through tubes and as air blows with the assistance of fans, it blows across the fins of the radiator to cool the fluid. WebDefinition: Radiation heat transfer is the process by which the thermal energy is exchanged between two surfaces obeying the laws of electromagnetics.
