An intercooler is a mechanical device used to cool a gas after compression process. Compression process increases the internal energy of the gas which in turn raises its temperature and reduces the density. In other words intercooler is a device used in compression process, typically a heat exchanger that removes waste heat in a gas compressor. They are used in many applications, including air compressors, air conditioners, refrigeration, and gas turbines, and automotive engines. Here they are widely known as an air-to-air or air-to-liquid cooler for forced induction (turbocharged or supercharged) internal combustion engines to improve their volumetric efficiency, which they do by increasing intake air density through nearly constant pressure cooling. First introduced in 1977 on the Porsche 911, although these were the first cars to use intercoolers they were not the first cars to use turbochargers; in fact they weren’t even the first 911’s to use turbochargers.
