HOT器件用旋转式斯特林制冷机研究进展

随着碲镉汞（mercury cadmium telluride,MCT）材料制备工艺的改进和提升，芯片组件的暗电流得到一定程度的抑制，红外探测器芯片组工作温度上升成为发展趋势。高工作温度（high operation temperature）器件的发展推动着小型低温斯特林制冷机向更小尺寸（size）、更小重量（weight）、更低功耗（power）、更低成本（price）、更好性能（performance）的方向发展。本文介绍了HOT器件用斯特林制冷机的SWaP3设计理念，薄壁管短冷指、高效小尺寸控制器、综合热管理、可靠性预测等设计技术，总结了近年国内外HOT器件用旋转式斯特林制冷机的研制进展。

Overview of Micro-Rotary Stirling Cryocoolers for HOT IR detectors

With the improvement and promotion of the Mercury Cadmium Telluride (MCT) material preparation process, the dark current of the FPA is suppressed to a certain extent, and an increase in the operating temperature of IR detectors has become a development trend. The development of high-operating-temperature IR detectors promotes the development of micro-Stirling cryocoolers to reduce the size, weight, power consumption, and cost, and promote their performance. The SWaP3 design concept of Stirling cryocoolers for HOT IR detectors is presented. Design techniques such as thin-walled tube short cold fingers, high-efficiency small-size controllers, comprehensive thermal management, reliability prediction, and the recent domestic and foreign development status of Stirling cryocoolers for HOT IR detectors are summarized.
