Abstract

Sumitomo (SHI) cryogenics has been a pioneer and industry leader in developing cryocoolers for all major cryogenic applications including healthcare, semiconductor manufacturing, laboratory research, and quantum computing, for customers globally. With the rising demand for high temperature superconducting (HTS) applications like high field magnets, fusion and power devices, (superconducting magnetic energy storage (SMES), and fault current limiters (FCLs)), we have increased our efforts in the last decade to develop and offer cryogenic cooling solutions like single stage Gifford-McMahon (GM) cryocoolers and cryogenic circulating cooling systems to address the needs of our global customers.

In this paper, we will discuss the design challenges, integration concerns, test findings and application examples for the high-capacity GM cryocoolers and cryogenic circulating systems developed by Sumitomo (SHI) Cryogenics of America Inc. We will also delve into comparing legacy systems to potential new systems identifying benefits and limitations.

用于高温超导应用的高容量GM制冷机和循环冷却系统的开发

Sumitomo (SHI) cryogenics一直是为全球客户开发所有主要低温应用（包括医疗保健、半导体制造、实验室研究和量子计算）的低温冷却器的先驱和行业领导者。随着对高温超导（HTS）应用的需求不断增长，如高场磁体、聚变和功率器件、超导磁能存储（SMES）和故障电流限制器（fcl）)，我们在过去十年中加大了开发和提供低温冷却解决方案的努力，如单级吉福德-麦克马洪（GM）制冷机和低温循环冷却系统，以满足我们全球客户的需求。在本文中，我们将讨论由美国住友（SHI） Cryogenics公司开发的大容量GM制冷机和低温循环系统的设计挑战、集成问题、测试结果和应用实例。我们还将深入研究将遗留系统与潜在的新系统进行比较，以确定其优点和局限性。
