Abstract
Joule-Thomson cooler have its unique advantages with respect to compact, light and low cost. Joule-Thomson coolers have been widely used in HgCdTe infrared detectors, InSb infrared detectors and InAs/GaSb superlattice infrared detectors. The performance of Joule-Thomson coolers is required to be improved with the development of higher mass and larger diameter focal plane infrared detectors. Joule-Thomson coolers use a limited supply of high pressure gas to support the cooling of infrared detectors. 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 of Joule-Thomson coolers. Experiments were carried out to focus on the performance of Joule-Thomson coolers coupled with infrared detectors. The effect of ambient temperature, the state of supply gas pressure is considered. The relationship between volume rates and supply gas pressure was proved to fit some regulates while the other parameters are fixed. Moreover, the effects of ambient temperature are analyzed.
