More Information
Summary:A cryogenic refrigerator has a separating device provided between a lower temperature portion and a heat exchanger to selectively separate the lower temperature portion and the heat exchanger, and thus to selectively block heat transfer between the lower temperature portion and the heat exchanger. According to the cryogenic refrigerator, it can have an ability to perform a maintenance operation of the cryogenic refrigerator at normal temperature by blocking heat transfer from the lower temperature portion to the heat exchanger during maintenance after disassembly.
