26 October 1998 Low-cost Joule Thomson coolers: single-flow flat cooler and two-flow cylindrical cooler
Author Affiliations +
Regardless improvements of Stirling and Pulse Tube coolers performances, Joule Thomson coolers are still interested for systems which require very fast cool down, compactness and high reliability. AIR LIQUIDE-DTA- believes that most of the future applications for Joule Thomson coolers would required devices such as single flow or dual flow coolers if manufacturers are able to increase significantly the performances and decrease the cost of such coolers. AIR LIQUIDE-DTA- has developed recently new technologies in order to match this challenge and to widen its range of low cost coolers. Previous developments such as memory shape valve and flat cooler were improved and adapted for cylindrical coolers. Original heat exchanger was also realized for flat cooler applications. Prototypes and results are presented in this paper for coolers with a target price which shall not exceed 200 USD.
