Regenerative cooling is a method of
cooling
Cooling is removal of heat, usually resulting in a lower temperature and/or Phase transition, phase change. Temperature lowering achieved by any other means may also be called cooling.

gases in which compressed gas is cooled by allowing it to expand and thereby take heat from the surroundings. The cooled expanded gas then passes through a
heat exchanger
A heat exchanger is a system used to transfer heat between a source and a working fluid. Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contac ...

Pulse tube refrigerator
The pulse tube refrigerator (PTR) or pulse tube cryocooler is a developing technology that emerged largely in the early 1980s with a series of other innovations in the broader field of thermoacoustics. In contrast with other cryocoolers (e.g. appl ...

In 1857, Siemens introduced the regenerative cooling concept with the
Siemens cycle. In 1895,

Carl von Linde
Carl Paul Gottfried von Linde (11 June 1842 – 16 November 1934) was a German scientist, engineer, and businessman. He discovered the refrigeration cycle and invented the first industrial-scale air separation and gas liquefaction processes, ...
in Germany independently developed and patented the
Hampson–Linde cycle to liquefy air using the
Joule–Thomson expansion process and regenerative cooling.
Hydrogen through the Nineteenth Century

A cryocooler is a refrigerator designed to reach cryogenic temperatures (below 120 K, -153 °C, -243.4 °F). The term is most often used for smaller systems, typically table-top size, with input powers less than about 20 kW. Some can have inpu ...
