Conceptual Design of a New Magnetic Refrigerator Operating between 4 K and 20 K
Abstract
A thermodynamic cycle analysis has been performed on a new magnetic refringeration system for liquid helium. This system features the use of two heat switches and a small helium-gas refrigerator to establish a high-temperature heat sink. As a result of cycle analysis, it is clarified that cooling power of 1 W at 4.5 K can be attained.
