According to designation, automotive radiators can perform various functions. The engine radiator maintains the temperature optimal for its operation and it is very important element of the cooling system. It is mounted in the front part of vehicle and is protected from mechanical damages with the special grill.
Liquid inside of the radiator moves through pipes of different cross-section, plates or corrugated band, speeding up its cooling, are molded to it. Fans, blowing to the radiator with cold air, and diffusers which regulate air flow direction are used for higher efficiency of heat-exchange processes. Excessive pressure release is performed by the radiator cap, equipped with inlet and drain valves.
Heating radiators serve for cabin heating. They are constructed in the same way, but in their construction there are swirlers in order to improve heat-exchange. The oil radiator, usually is used as auxiliary, serve for oil cooling in the lubrication system of the engine, transmission, liquid in the steering control, and also sometimes for oil in the reductor.
