Cooling system and cooling method |
摘要 |
A cooling system for cooling a superconducting device by a low-temperature fluid is provided. A flow generator for producing a flow in the low-temperature fluid is provided in the cooling system. The low-temperature fluid flowing through the superconducting device is heated. The flow generator is used to produce a flow in the heated low-temperature fluid. The low-temperature fluid is cooled and supplied to the superconducting device. |

1. A cooling system for cooling a superconducting device or component, the cooling system comprising:
a liquid outlet configured to supply a liquefied coolant fluid to the superconducting device or component; a gas-liquid mixture inlet configured to receive a gas-liquid mixture coolant fluid flowing from the superconducting device or component; a coolant line connecting the gas-liquid mixture inlet to the liquid outlet and comprising a gas outlet, a gas inlet, a first coolant line part connecting the gas inlet to the liquid outlet, a second coolant line part connecting the gas-liquid mixture inlet to the gas outlet, and a third coolant line part connecting the gas outlet to the gas inlet; a low-temperature chamber configured to accommodate the first coolant line part and the second coolant line part, wherein the third coolant line part is provided outside the low-temperature chamber; a cooling device comprising at least one cooling stage provided inside the low-temperature chamber and thermally coupled to the first coolant line part such that a gaseous coolant fluid flowing from the gas inlet through the first coolant line part is liquefied to generate the liquefied coolant fluid; a heating device provided inside the low-temperature chamber and thermally coupled to the second coolant line part such that the gas-liquid mixture coolant fluid is completely gasified to the gaseous coolant fluid; and a flow generator arranged on the third coolant line part to generate a flow of the gaseous coolant fluid in the third coolant line part, wherein the cooling device comprises a single stage refrigerator comprising a first cooling stage and a two-stage refrigerator comprising a first cooling stage and a second cooling stage, the first cooling stage of the single stage refrigerator, the first cooling stage of the two-stage refrigerator and the second cooling stage of the two-stage refrigerator arranged in series along the first coolant line part. |
