Superconductor device cooling installation, has restriction unit such that, when device is overheated, liquid in main reservoir flows to auxiliary reservoir by vaporized liquid pressure and flows again to main reservoir when pressure is low

摘要

The installation has a connection duct between bases of main and auxiliary reservoirs (1, 9). An outlet collector (7a) connected to the reservoir (1) has a restriction unit (11) such that, during overheating of a superconductor device (4), a cryogenic liquid in reservoir (1) flows back, by vaporized liquid pressure, towards the reservoir (9) from where liquid flows again by gravity towards the reservoir (1) when the pressure is reduced.
