Charge Air Cooler: Meaning, Use and Key Difference

A charge air cooler is an automotive heat exchanger, commonly called an intercooler. It reduces the temperature of compressed air before that air enters an engine, supporting the engine's operating requirements. The term does not describe a chargeable portable air cooler or a household appliance. If you want cooling for a room, browse evaporative air coolers, portable air conditioners or fans according to the technology you need; if you are diagnosing a vehicle, use the engine and vehicle service documentation.
