摘　　要：针对超长线列焦平面器件对制冷机性能的要求,开展了斯特林制冷机与超长线列焦平面探测器耦合过程中冷量损失的研究。实验结果表明耦合过程中在导热损失一定情况下,热辐射损失在不同结构中对斯特林制冷机的降温时间和制冷量有较大影响,模拟计算与实验结果一致。Based on the large infrared focal plane calling for the performance of cryocoolers,the characteristics of cold loss between Stirling cryocooler and large infrared focal plane was studied. The results show that the hot radiate have a important effect on the cold time and refrigeration when the heat conduction are the constant,the simulation calculate accord with the experimentation well,to provide optimized design for long life Stirling cryocooler.
