The authors have developed 310W @-100℃(173K) and 40W @-200℃(73K) Stirling coolers which are designed to be suitable for the cooling temperatures in ultra-low temperature range using the same driving parts. The difference between both the Stirling coolers results from a structure of heat exchangers. The former adopts a plate-fin type heat absorber and rejecter and an annular type regenerator. Meanwhile the latter adopts a cold head as the heat absorber, a gap type heat rejecter and a circular type regenerator. The cooling performances of both the Stirling coolers are the same tendency according to the cooling temperature, but the former measures of increase in cooling capacity and decrease in motor input are so bigger than the latter. The refrigeration systems for industrial use are built up by the former using a secondary heat transfer fluid circuit and also by the latter using direct cooling at the cold head. Those system take effect on the environment problem arising on a terrestrial scale.
