Cooling method and system

摘要

A cooling fluid system is disclosed for providing cryogenic cooling fluid to a high temperature super-conducting rotor (24) comprising: a cryogen storage tank (52) storing a liquid cryogenic cooling fluid (62); an inlet transfer line (56) connecting the storage tank to the rotor and forming a passage for liquid cooling fluid to pass from the tank to the rotor, wherein said storage tank is elevated (54) above the rotor and the liquid cooling fluid is gravity fed to the rotor.
