More Information
Summary:The utility model discloses a coaxial pulse tube refrigerating machine with small holes and air vesicle, belonging to the field of an air refrigerating machine. The utility model discloses the refrigerating machine which has compact structure, having no moving part under the low temperature, having liquid nitrogen with long-life, and having a temperature range under the liquid nitrogen. The utility model is characterized in that the coaxial pulse tube refrigerating machine with small hole and air vesicle can be used for reducing the refrigerating temperature. The coaxial pulse tube refrigerating machine with small hole and air vesicle adopts the low thermal conductivity material to solve the problem of thermal insulation and thermal leakage between a pulse tube and a regenerator; an air distributing device can be used for solving the problem of inhomogeneous air-flow distribution. The utility model solves the practical problem of the pulse tube refrigerating machine, in particular to the technical field of military affairs and the space technology, and the high-temperature superconductor.
