Liquid nitrogen recondenser |
| abstract |
[PROBLEMS] To recondensate an evaporated nitrogen gas G at a low cost and maintain the degree of vacuum in a vacuum vessel 12 of a refrigerator 31 for a long period of time. To provide a liquid nitrogen recondensing device 30 capable of properly maintaining the functions of the liquid 32 for a long period of time. Focusing on the fact that the recondensing temperature of nitrogen gas G is around 77K and that the vacuum suction action for maintaining vacuum is possible at around 20K, it has a first cooling stage 34 and a second cooling stage 35. A refrigerator 31, a vacuum vessel 12 containing a first cooling stage 34 and a second cooling stage 35, a recondenser 32 which is in thermal contact with the first cooling stage 34 and is capable of recondensing nitrogen gas G; Recondenser 32 And a vacuum adsorber 33 that is in thermal contact with the second cooling stage 35 and faces the inside of the vacuum vessel 12. |
