Cryocoolers: state of the art and perspectives.

Cryoréfrigérateurs : état de l'art et perspectives.

Author(s) : RAVEX A.

Summary

Cooling at cryogenic temperatures is traditionally achieved by using latent evaporation heat of cryogenic fluids (liquid nitrogen or helium). These cryogenic fluids are generally produced in industrial-separation and liquefaction installations and are then distributed to users. For some applications, the use of these fluids poses operational problems (in particular in space or remote-site applications) and an available cooling or a local or system-related liquefaction system is desirable. The development of mechanical cryorefrigerators aims at responding to those needs. This kind of cryocooler or liquefier (Gifford-MacMahon, Stirling or Brayton-type systems) now exist on the market. New technologies are also being developed (pulse tubes, Turbo-Brayton). The state of the art and the ongoing developments are presented along with examples of integrated systems. These technologies could find applications in the food and biological sectors. This article is a PowerPoint presentation.
