已经开发出一种带有孔板脉冲管制冷机的紧凑型液氮再冷凝器。再冷凝能力约为170cm 3 /h。再冷凝器中采用的孔板脉冲管制冷机是阀门式的，由住友重工业株式会社商品化。该制冷机在 77 K 时可提供超过 10 W 的冷却功率，制冷机冷头和旋转阀单元之间有 4 m 长的连接管。制冷机采用额定输入功率1.6kW的风冷氦压缩机组。除压缩机单元和旋转阀单元外，再冷凝器的直径为113毫米，高度为567毫米，重量为6公斤。再冷凝器和低温冷却器对于许多科学、医疗和工业应用来说方便且灵活。本文介绍了再冷凝器的设计和测试结果，以及脉冲管制冷机的冷却性能。
A compact liquid nitrogen recondenser with an orifice pulse tube cryocooler has been developed. The recondensation capacity is about 170 cm 3 /h. The orifice pulse tube cryocooler employed in the recondenser is a valved type, and is commercialized by Sumitomo Heavy Industries Limited. The cryocooler delivers a cooling power of more than 10 W at 77 K with a connecting tube of 4 m between the cold head of the cryocooler and a rotary valve unit. An air-cooled helium compressor unit with a rated input power of 1.6 kW is applied for the cryocooler. Excepting the compressor unit and the rotary valve unit, the recondenser is 113 mm in diameter, 567 mm in height, and 6 kg in weight. The recondenser and the cryocooler are handy and flexible for many scientific, medical and industrial applications. This paper describes the design and the test result of the recondenser, as well as the cooling performance of the pulse tube cryocooler.
