Circulation cooling system of cryogenic cable

摘要

The present invention provides a circulation cooling system of a cryogenic cable in which a reserver unit can be made smaller and a conventional adjustment mechanism or adjustment task of the amount of a refrigerant within a reserver unit is not necessary. The circulation cooling system of a cryogenic cable according to the present invention has a reserver unit storing a refrigerant and a cable cooling portion cooling down a cable by the refrigerant sent from the reserver unit and the refrigerant sent from the cable cooling portion is returned to the reserver unit again for circulation. The system is characterized in that it has a refrigerant temperature adjustment mechanism to keep constant the amount of the refrigerant within the reserver unit.
