ABSTRACT:
Cryogenic liquid coolant for cooling the rotor of a superconducting generator is deposited on the inner surface of a rotating conduit extending within the rotor, forming an annulus of liquid surrounding a vapor core. The liquid coolant from the rotating tube is transferred to two radial tubes in the rotor and, upon emerging therefrom, splashes on the surface of a pool of coolant bathing the rotor windings. Evaporated coolant is returned from the rotor in separate streams from the driven end and the collector end, allowing cooling of the driven and collector ends to be equalized by independently controlling flow of the returning streams. The liquid coolant supply pressure determines the position of the coolant pool surface in the rotor.
