【摘要】:為實現(xiàn)在復雜外熱流條件下對CO_2探測儀紅外探測器組件溫度的有效控制,對其進行了詳細的熱設計。對紅外探測器周圍外熱流進行分析,確定了其散熱面位置;诩t外探測器所處空間熱環(huán)境以及自身高功耗、低熱控指標的特點,提出熱設計方案。對紅外探測器組件有限元模型進行了熱分析計算,得到各個轉(zhuǎn)角姿態(tài)下的紅外探測器組件的溫度范圍為-31.8~-26.9℃,計算結果滿足設計要求。通過CO_2探測儀熱平衡試驗對熱設計進行了驗證,試驗中紅外探測器組件的溫度范圍為-32.6~-30.1℃,試驗結果與計算結果基本一致,滿足熱控指標要求,說明熱設計方案在復雜外熱流條件下合理可行,具有較好的適應性。
[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,
