Title:
DEVICE FOR PROVIDING LIQUID HELIUM FORCED-FLOW COOLING WORKING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/143641
Kind Code:
A1
Abstract:
Disclosed in the present invention is a device for providing a liquid helium forced-flow cooling working medium. The device comprises a thermal-load liquid helium tank system, a circulating-pump liquid helium tank system, a supercooled-helium liquid helium tank system, a device process pipeline, and a cooling box. The thermal-load liquid helium tank system consumes and absorbs a thermal load of a low-temperature user; the circulating-pump liquid helium tank system consumes and absorbs a thermal load of a circulating pump; the supercooled-helium liquid helium tank system consumes and absorbs a thermal load of supercooled helium; and the device process pipeline and the cooling box realize a low-temperature user precooling process, a liquid helium tank precooling and liquid-storage process and a rotating machine precooling and starting process, and provide a liquid helium forced-flow cooling working medium for the low-temperature user, so as to realize the operation of the low-temperature user. The device for providing a liquid helium forced-flow cooling working medium disclosed by the present invention can effectively reduce a thermal load of a liquid helium forced-flow cooling device by means of optimizing a liquid helium forced-flow cooling circulation manner and using an energy level gradient to manage low-temperature thermal loads at different levels, thereby reducing the investment scale and operation cost of a helium low-temperature system.
