Cryogenic cooling system and method

Abstract:

A cryogenic cooling system (CCS) includes a cylindrical housing having a first end and a second end. Also, the CCS includes a displacer disposed within the cylindrical housing and reciprocatingly driven between the first end and the second end of the cylindrical housing to compress or expand a refrigerant gas in a gas chamber. Further, the CCS includes a tubing unit coupled to the second end of the cylindrical housing and disposed adjacent to the at least one superconducting unit, wherein the tubing unit is configured to circulate the refrigerant gas received from the cylindrical housing through the tubing unit to absorb the at least one heat load imposed on the at least one superconducting unit to generate heated refrigerant gas, and convey the heated refrigerant gas to the gas chamber of the cylindrical housing to reduce or maintain a temperature of the at least one superconducting unit.
