Radiator


Radiator refers to a cooling system that works as a heat exchanger by circulating hot coolant through the engine by getting it circulated by the water pump.

The radiator is a heat exchanger that removes the heat from the engine coolant passing through it, The heat transfers from the hot coolant to the cooler outside air.

An automotive radiator is composed of three main parts.  The radiator core, inlet, and outlet tanks. The core is usually made of aluminum, The tanks may be made of plastic or metal. The core has two sets of passages, a set of tubes and as et of fins attached to tubes, The tubes run from the inlet tank to the outlet tank. Coolant flows through the tubes and air flows between the fins, The hot coolant sends heat through the tubes to the fins. The outside air passing between the fins picks up and carries away the heat which lowers the temperature of the coolant
