摘要:
Provided is a cooling device for a superconductive cable which can be installed in a limited installation space with an efficient arrangement. A cooling device (10) cools a superconducting cable (11), by supplying and circulating a refrigerant. The cooling device (10) includes a reservoir tank (12) which stores the refrigerant, a circulation pump unit (13) which pumps the refrigerant, and a cooling unit (14) which cools the refrigerant. The circulation pump unit and the cooling unit are accommodated in the reservoir tank, whereby a compact cooling device can be achieved.
摘要:
A superconducting cable comprises a superconductor 60, two or more coolant passages including an outgoing coolant passage 12 and a returning coolant passage 14 that transfer a coolant that cools the superconductor, and a heat insulating pipe 10 inside which the superconductor 60 and the coolant passages are formed. For the coolant passages, by a double structured tube of an inner tube 6 and an outer tube 8, the outgoing coolant passage 12 is formed in the internal space of the inner tube 6 and the returning coolant passage 14 is formed in the space between the inner tube 6 and the outer tube 8, the inner tube 6 is formed between the outgoing coolant passage 12 and the returning coolant passage 14 of a heat insulating material, the superconductor 60 is disposed on the outer circumferential side of the inner tube 6, and the superconductor is cooled by the coolant that flows through the returning coolant passage.
