Paper Abstract

Joule-Thomson coolers have been widely used in infrared photo-detector, which have their unique advantages with respect to compact, light and low cost. The performance of Joule-Thomson coolers is required to be improved with the development of higher mass and larger diameter focal plane infrared photo-detector. In order to maximize the usage time and minimize the cooling down time for a given volume of stored gas for Joule-Thomson coolers, it is important to study on fluid flow and heat transfer of Joule-Thomson coolers. Experiments and analysis are carried on to investigate the parameters of Joule-Thomson coolers. The effects of ambient temperatures are considered. It is useful to study the performance of Joule-Thomson coolers for large diameter focal plane infrared photo-detector. Deep research on Joule-Thomson coolers will be helpful to explore optimization of the Joule-Thomson coolers for infrared photo-detectors.
