Amélioration de la performance d'un cryorefroidisseur à pulsation fonctionnant à 4 K.

Increase in performance of a 4 K pulse tube cryocooler.

Auteurs : REVEX A., TROLLIER T., TANCHON J., et al.


The helium enthalpy variation with temperature and pressure in the operating range of 4 K cryocoolers is by far different from ideal gas. This real gas behaviour leads to large irreversibility in regenerator operation. It is theoretically possible to reduce these losses and recover some "free" cooling power by implementing heat intercepts in the regenerator. The authors have experimentally confirmed this opportunity with a commercial 4 K pulse tube. Several hundred mW of "free" cooling power in the temperature range of 6 to 20 K have been obtained without any degradation in the initial cooling power at 4 K. The experimental set up is described and experimental results presented and discussed.
