摘要
随着航天技术对更大视场、更高分辨率的需求,线列红外探测器规模越来越大,传统的制冷机与红外探测器单点耦合方式,已经无法满足超长线列红外探测器芯片温度均匀性的要求。结合国内外多家研究单位的设计及试验情况,对各类柔性冷链进行了对比分析,从热学性能及力学性能出发,总结了各类柔性冷链设计的特点及其适用性。
With the demand of from space technology for a large field of view and higher resolution,the scale of line infrared detectors is increasing.Single point coupling mode fails to meet the temperature uniformity requirement of long linear infrared detector chips.This study compares and analyzes various types of flexible thermal links,based on the design and the testing outcomes from many domestic and international research institutes.The characteristics and applicability of the various flexible thermal link designs,in terms of thermal and mechanical properties,are summarized.
