高频微型脉冲管制冷机的实用化研究

Applications of High Frequency Miniature Pulse Tube Cryocoolers

脉冲管制冷机经过多年的发展,性能不断改善,目前已开始进入实用化阶段。高频微型脉冲管制冷机结构紧凑,应用方便,并且主要工作在需求量较大的液氮温区,因此将首先得到一定规模的应用。介绍了作者针对脉冲管制冷机在红外和超导方面的应用所作的实用化工作,讨论了尚待解决的问题。

Pulse tube refrigerator is now approaching practical applications High frequency pulse tube coolers are compact and easy to use, and mostly works in the liquide nitrogen temperature region They are likely to be first practically used to a considerable scale This paper reports the work of the authors on this topic and discusses the problems to be solved
