Lightweight high-capacity pulse tube cryocooler holds significant potential for cooling infrared detectors in various applications. In this work, a comprehensive analysis was undertaken to identify the key parameters for the cryocooler weight reduction.A miniature cold finger was designed and optimized using a small compressor.At present, a novel and lightweight single-stage coaxial pulse tube cryocooler has beendeveloped. It demonstratesa cooling power of 11 W at 80 K andwith frequency of 102 Hz.Notably, the cryocooler exhibits a significantly reduced weight of 4.4 kg,which isless than half the weight of a conventional 10W/80Kcryocooler.

运行温度为 80 K 的轻型大容量脉冲管制冷机

轻质大容量脉冲管制冷机在冷却各种应用中的红外探测器方面具有巨大的潜力。本工作对制冷机减重的关键参数进行了综合分析，利用小型压缩机设计并优化了微型冷指。目前，已开发出一种新型、轻量化的单级同轴脉冲管制冷机。它在 80 K 和 102 Hz 频率下的冷却功率为 11 W。值得注意的是，该制冷机的重量显着减轻了 4.4 kg，不到传统 10W/80K 制冷机重量的一半。
