摘　　要：随着航天遥感应用对大视场、高分辨率探测的需求,红外探测器规模越来越大。红外探测器需封装在杜瓦内工作,杜瓦热负载是杜瓦一个重要指标。本文设计并搭建了大规模探测器杜瓦热负载测试实验装置,测得长波杜瓦组件不同外壳温度下的热负载,为实际工程应用提供了重要数据。As aerospace remote applications demand a wider field of view with higher resolution,the format of infrared detectors is increasing.An infrared detector must be packaged in a dewar to work,and the thermal load is an important parameter of the dewar.A thermal load testing device was designed and developed,and the thermal load of a long-wavelength infrared dewar at different shell temperatures was measured,which provides important data for practical engineering applications.
