【Abstract】 A subcooled LHe refrigerator (λ-point temperature) has been designed and in-vestigated experimentally. Its design methods have been studied. Its LHeI heat ex-changer heat loss coling capacity and cooling-down time have also been calculated andcompared with the experimental results, showing that the device is simple in construc-tion, easy in operation and uses small amount of Helium.更多还原
