商业高温超导（HTS）线限制我们的工作温度范围从20到40 K的场极磁铁应用于旋转机械。我们建议在基于转基因冷冻冰箱的闭式循环热虹吸中使用氦气和氖气的混合物。在100千瓦级高温超导同步电机上，讨论了氦氖混合冷却与闭式循环热虹吸耦合形成的蒸发器在外部热负荷下的温度稳定性。设计了包括冷凝器在内的国产冷却系统。根据热学和力学分析，蒸发器组装在电机内。蒸发器的冷却与100千瓦级高温超导同步电机应用于一个可变热负荷等效的实际高温超导转子场极。我们报告了这些结果，并提出了它在大型船舶推进电机上的潜在应用。
Commercial high-temperature superconducting (HTS) wires restrain us to an operation temperature ranging from 20 to 40 K for field-pole magnets applied to rotating machinery. We have proposed to employ a mixture of helium and neon gas in a closed-cycle thermosyphon based on a GM cryo-refrigerator. In this paper, we discuss the temperature stability of the evaporator created by a helium-neon mixture cooling coupled with a closed-cycle thermosyphon, upon an external heat load on a 100-kW-grade HTS synchronous machine. A home-made cooling system, including the condenser, was designed. The evaporator was assembled within the motor in accordance with thermal and mechanical analysis. The cooling of the evaporator with the 100-kW-grade HTS synchronous motor was applied against a variable heat load equivalent with the actual HTS rotor field poles. We report these results and propose its potential application to a large-scale ship propulsion motor.
