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.

A compound cycle engine system has a rotary engine, which rotary engine generates exhaust gas. The system further has a compressor for increasing the pressure of inlet air to be supplied to the engine to a pressure in the range of from 3.0 to 5.0 atmospheres and an intercooler for providing the inlet air to the engine at a temperature in the range of from 150 to 250 degrees Fahrenheit. The system further has one or more turbines for extracting energy from the exhaust gas. The Miller Cycle is implemented in the rotary engine, enabling the compression ratio to be lower than the expansion ratio, allowing the overall cycle to be optimized for lowest weight and specific fuel consumption.

High-Pressure Gas Compressor And Method Of Operating A High-Pressure Gas Compressor
ActiveUS20080213115A1Reduce in quantitySimple manufacturing processPositive displacement pump componentsFlexible member pumpsFriction reductionInlet valve
A high-pressure gas compressor comprises a single-acting cam driven piston with a pressure compensation chamber disposed between the piston and the cam. A roller tappet assembly transmits reciprocating motion from the cam to the piston. A pressurized gas directed to the pressure compensation chamber offsets forces acting on the piston from the compression chamber gas pressure, thereby reducing Hertzian pressure between the tappet roller and the cam. Overall efficiency and durability can be improved by reducing friction between compressor components, for example by employing thin film coatings to reduce friction, pressurized oil lubrication systems and higher cylinder bore diameter to piston stroke ratios. The service life of gas seals and compression efficiency can be improved by thermal management strategies, including liquid-cooled compressor cylinder liners and intercoolers between compression stages. Employing a poppet-style intake valve and reducing parasitic volume in the compression chamber can improve compressor volumetric efficiency.
