Abstract
A cooling fluid system is disclosed for providing cryogenic cooling fluid to a high temperature super-conducting rotor comprising: a re-circulation compressor; a storage tank having a second cryogenic fluid; an inlet line connecting the re-circulation compressor to the storage tank and to the rotor, and forming a passage for cooling fluid to pass from the re-circulation compressor through the storage tank and to the apparatus.
Claims19
A cooling fluid system for providing cryogenic cooling fluid to an apparatus comprising:
- a re-circulation compressor;
- a storage tank having a cryogenic fluid;
- an inlet line connecting the re-circulation compressor to the storage tank and to the apparatus, and forming a passage for cooling fluid to pass from the re-circulation compressor through the storage tank and to the apparatus, and
- a return line providing a fluid passage for the cryogenic fluid flowing from the apparatus to the re-circulation compressor.
A cooling fluid system coupled to a high temperature super-conducting rotor for a synchronous machine, said system and a source of cryogenic cooling fluid comprising:
- a re-circulation compressor;
- a cryogenic storage tank storing a supply of cryogenic fluid;
- an inlet line providing a fluid passage for cooling fluid between the re-circulation compressor and the rotor, wherein the inlet line passes through the storage tank, and
- a return line providing a fluid passage for the cooling fluid between the rotor and re-circulation compressor.
A method for cooling an apparatus using a cooling fluid system having a cooling fluid circuit, a cryogenic storage tank, a heat exchanger and inlet and return lines for cooling fluid, said method comprising the steps of:
- a. pumping the cryogenic cooling fluid through the inlet line, through the heat exchanger, the storage tank and into the machine;
- b. transferring heat from the cooling fluid in the inlet line at the heat exchanger and into the return line, where the inlet and return lines pass through the heat exchanger;
- c. cooling the cooling fluid to cryogenic temperature in the storage tank, and
- d. returning used cooling fluid from the apparatus, through the return line and back to the inlet line.
