Abstract
A cryogenic system includes a containment vessel in which a body to be cooled is housed in such a manner that the body is immersed in a liquid coolant; a tubular refrigerator sleeve; and a refrigerator, inserted in the opening section of the refrigerator sleeve, for recondensing coolant gas generated from the coolant, wherein a gas flow-forming means for forming a flow of purge gas toward an opening section of the refrigerator sleeve is provided. The purge gas prevents air from entering a refrigerator sleeve during the replacement of a refrigerator of a cryogenic system.
Claims11
A cryogenic system comprising:
- a body to be cooled;
- a containment vessel in which said body to be cooled is housed in such a manner that said body is immersed in a liquid coolant;
- a tubular refrigerator sleeve having a base section communicatively connected into said containment vessel and an opening section which can be opened or closed to the outside;
- a refrigerator for recondensing coolant gas generated from the coolant, said refrigerator being inserted through said opening section of said refrigerator sleeve;
- and
- a gas flow-forming means for forming a flow of purge gas from said base section of said refrigerator sleeve to said opening section when said opening section directly opens to outside, thereby blowing out external air which otherwise enters into said refrigerator sleeve via said opening section.
A cryogenic system comprising:
- a body to be cooled;
- a vacuum vessel in which said body to be cooled is housed;
- a tubular refrigerator sleeve having a base section connected to said body, an opening section which can be freely opened or closed to the outside, and a side wall for separating an inner section of said vacuum vessel from outside;
- a refrigerator for cooling said body, said refrigerator being inserted through said opening section of said refrigerator sleeve;
- and
- a gas flow-forming means for forming a flow of purge gas from the base section of the refrigerator sleeve to the opening section when said opening section directly opens to outside, thereby blowing out external air which otherwise enters into said refrigerator sleeve via said opening section.
