Honda Civic Radiator

Radiators are heat exchangers used to transfer thermal energy from one medium to another, both for cooling purposes and for heating. A radiator is a device comprising a large amount of cooling surface containing large quantities of air to cool off water efficiently.  The component has a wide variety of automotive applications.  The cooling of the internal combustion engine is primarily why they are used in automobiles.

The radiator would transfer the heat from the internal fluid to the outside air, thereby cooling the fluid, which would then cool the car engine in turn. Radiators are also used to cool automatic transmission fluids, refrigerant air conditioner, intake air, and also to cool engine oil or power steering fluid.

A cooling system will work by sending liquid coolant through passages in the block and heads of the engine. This would pick up heat from the car engine as the coolant would flow through these passages. The heated fluid would then make its way through a rubber hose in the front of the car to the radiator.

As such, heat is forced away from the parts of the engine which would keep the vehicle free from overheating. The radiator is usually placed behind the grill of the vehicle to hold the radiator, the fluid inside it, and the engine in peak conditions, while cold air is forced through it.
