    Sumitomo (SHI) Cryogenics of America Inc has developed a novel cryogenic cooling system integrating a remote cooling gas flow circuit with a Gifford-McMahon (GM) cryocooler to cool a remote load. This innovative approach eliminates the need for a separate gas flow circuit and circulator, leading to an efficient, compact, and cost-effective solution for various cryogenic applications. This...

    Sumitomo (SHI) Cryogenics of America, Inc. has investigated the capabilities of a circulating cooling system utilizing a Sumitomo CH-160 High-Capacity Gifford-McMahon (HCGM) cryocooler and helium gas circulator for cooling a remote thermal load (e.g., a superconducting magnet). System cooling performance was investigated for circulation loop pressures of up to 20 bar-g. The system is...

    Stirling-type pulse tube cryocoolers are known for their compact design, reliability, and long operational life, but traditional systems are primarily limited to small-scale cooling applications. To meet the growing demand for high cooling capacity in fields such as superconducting power transmission, small-scale gas liquefaction, and BOG (Boil-Off Gas) management, this paper presents a...

  4. 45. C3Or2A-04: Numerical Investigation of Alternative Regenerators in Regenerative Cryocoolers Operating Below 20K

    In regenerative cryocoolers, the regenerator plays a pivotal role, and often represents the largest source of losses among all components. Traditional materials, such as stainless-steel mesh, exhibit insufficient heat capacity below 20K, which leads to a decrease in system efficiency. While materials like HoCu2 and Er3Ni offer higher volumetric heat capacity, they are typically fabricated into...

    Contributed Oral

    Large-scale free-piston Stirling cryocoolers, capable of delivering several hundred watts of cooling power at 80 K, have significant potential applications in boil-off gas re-liquefaction and precooling processes. Recently, we proposed a novel parallel regenerator layout aimed at suppressing local acoustic streaming, which could enable further scaling of the cryocooler while maintaining high...
