Discharge Air Cooler

An air cooler works on the principle of evaporative cooling wherein evaporation of water is used to cool the air. A simple example of evaporative cooling is sweating in humans. As sweat starts to evaporate, it extracts the extra heat absorbed in it from the skin in the form of gas thus resulting in a cooling effect.Charge air coolers—otherwise known as intercoolers—act as the middleman between the turbo and the engine. They sit in front of the truck radiator and take the hot, compressed air from the turbo and cool it down before it reaches the engine. This increases engine efficiency and power.
