| titleOfInvention | Cryogenic cooling device |
| abstract | [PROBLEMS] To realize a closed-cycle cryogenic cooling device having a simple device configuration, high reliability, easy handling, and a cooling temperature in a superfluid helium temperature (1.8K) region. The purpose is to: SOLUTION: A GM refrigerator 21 is used as a pre-cooler, and a GM compressor unit B and a JT compressor unit C are connected to pipelines 23, 2 to a refrigerator unit A combined with a JT circuit. 4 and pipes 25 and 26, 3 He is used as a circulating gas for the JT circuit, and 4 He is used as a circulating gas for the GM refrigerator 21 for precooling. The JT compressor unit C is arranged in series. The primary pressure regulator 6 and the secondary pressure disposed between the one-stage vacuum pump 9 and the one-stage compressor main body 1 and the pipelines 25 and 26 connecting the JT circuit and the JT compressor unit C. The regulator 8 allows the low pressure side of the JT circuit to be maintained at a negative pressure and the high pressure side of the JT circuit to be maintained at a predetermined discharge pressure, and compresses the vacuum pump 9 and the compressor body 1 of the JT compressor unit C. A scroll type having a high ratio was used. |
