SUPERCONDUCTIVE SWITCH COOLED BY INNER CAVITY FILLED WITH LIQUID OR GASEOUS COOLANT Russian patent published in 2014 - IPC H01L39/20 

FIELD: electricity.

SUBSTANCE: invention is related to superconductive switches. The concept of the invention is as follows: the switch switching windings over between resistive and superconductive operation modes contains a body consisting of winding wound around spool and cavity with coolant cooling the winding. Partition separates inner cavity with coolant from external tank with coolant. Partition has small orifices allowing entry of liquid coolant flow into the inner cavity for the purpose of winding cooling. Size of one or several small orifices is comparable with bubbles of gaseous coolant in liquid coolant at normal operating conditions in the system of superconductive magnet cooling.

EFFECT: invention allows perfection of cooling conditions control for the superconductive switch.
