【摘要】：为实现在复杂外热流条件下对CO_2探测仪红外探测器组件温度的有效控制,对其进行了详细的热设计。对红外探测器周围外热流进行分析,确定了其散热面位置。基于红外探测器所处空间热环境以及自身高功耗、低热控指标的特点,提出热设计方案。对红外探测器组件有限元模型进行了热分析计算,得到各个转角姿态下的红外探测器组件的温度范围为-31.8~-26.9℃,计算结果满足设计要求。通过CO_2探测仪热平衡试验对热设计进行了验证,试验中红外探测器组件的温度范围为-32.6~-30.1℃,试验结果与计算结果基本一致,满足热控指标要求,说明热设计方案在复杂外热流条件下合理可行,具有较好的适应性。
[Abstract]:In order to effectively control the temperature of infrared detector module of CO_2 detector under complex external heat flow condition, the thermal design is carried out in detail. The heat flux around the infrared detector is analyzed and the position of the heat dissipation surface is determined. Based on the space thermal environment of infrared detector and the characteristics of its own high power consumption and low thermal control index, a thermal design scheme is proposed. The finite element model of the infrared detector assembly is calculated by thermal analysis. The temperature range of the infrared detector assembly is -31.8 鈩，
