摘　　要：在分析国内某卫星某载荷所用的长波长线阵多谱段红外探测器的冷量需求、降温时间、温度稳定性、可靠性及卫星可提供的功率、热控资源的基础上,确定了通过降低制冷机热端和压缩机温度以减少输入功率的开环控制设计方法;并对组件进行热平衡试验,试验数据表明,该方案功率需求较低、可靠性较高,是一种较好的制冷设计方案。Based on an analysis of cooling capacity demand, cooling - down time, stable temperature, satellite power and thermal control resource of long- wave infrared detector, an open -loop control method to decrease the temperature of the refrigerator hot end and the compressor and to reduce the input power was decided. A thermal balance experiment for its component was conducted. The results show that it is a ideal method with a low power and high reliability.
