'''Regenerative cooling''' is a method of [[Physics:Heat transfer|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 [[Physics:Heat exchanger|heat exchanger]] where it cools the incoming compressed gas.<ref>{{Cite web |url=http://www.ub.utwente.nl/webdocs/tn/1/t000001c.pdf |title=Cryogenic microcooling Pag.25 |access-date=2008-11-06 |archive-date=2012-02-18 |archive-url=https://web.archive.org/web/20120218155402/http://www.ub.utwente.nl/webdocs/tn/1/t000001c.pdf |url-status=dead }}</ref>

==History==
In 1857, Siemens introduced the regenerative cooling concept with the [[Physics:Siemens cycle|Siemens cycle]].<ref>Charles William Siemens, "Improvements in refrigerating and producing ice, and in apparatus or machinery for that purpose", British patent no. 2064 (filed:  July 29, 1857).</ref>  In 1895, William Hampson in England<ref>W. Hampson, "Improvements relating to the progressive refrigerating of gases", British patent 10,165 (filed:  May 23, 1895).</ref> and [[Biography:Carl von Linde|Carl von Linde]] in Germany<ref>Linde, Carl, "Verfahren zur Verflüssigung atmosphärischer Luft oder anderer Gase" (Method for the liquefication of atmospheric air or other gases), German patent 88,824 (filed:  June 5, 1895).</ref> independently developed and patented the [[Physics:Hampson–Linde cycle|Hampson–Linde cycle]] to liquefy air using the [[Physics:Joule–Thomson effect|Joule–Thomson expansion process]] and regenerative cooling.<ref>[https://history.nasa.gov/SP-4404/app-a1.htm Hydrogen through the Nineteenth Century]</ref> On 10 May 1898, James Dewar used regenerative cooling to become the first to statically [[Chemistry:Liquid hydrogen|liquefy hydrogen]].
