【摘要】 本文首先介绍了我们开发的可用于80K及以下温区的高频脉冲管制冷机。在此基础上,去掉了低温下一般都必用的维持高真空的真空罩,设计了新的结构,改进了脉冲管制冷机的设计以求在高温区维持较高的效率。实验表明改进后的脉冲管制冷机能达到-100℃的深冷温区,这为深冷温区微小冷量的用户开辟了一条新的思路。更多还原

【Abstract】 In the paper, the high frequency pulse tube coolers developed for 80K and below temperature application are introduced. Based on these work, remove the vacuum chamber for cryogenics, adopt new design for high temperature scope, a prototype PTC is designed and fabricated for -100 ℃ application. Experiments have been done and they show that -100 ℃ could be reached without vacuum chamber. This work gives a new approach for some small cooling power application at -100 ℃ temperature scope.更多还原
