摘要

为了实现大功率焦平面器件的热控制，根据焦面组件的结构特点，通过仿真计算与试验相结合的方法，对大功率焦平面的热控设计进行了研究。首先，介绍了大功率焦平面器件的主要热设计要求，分析了大功率焦平面器件、小散热空间并安装在移动构件上的焦面组件热设计的特点。接着，利用I-DEAS有限元分析软件建立热分析计算模型，利用TMG模块进行分析计算。然后，进行试验验证，并根据试验给出了焦平面器件升温拟合曲线。最后，根据热设计实例提出如何合理的选择大功率焦平面器件的热控制方式。结果表明，50W大功率焦平面器件连续工作2min时，在有12℃冷源的情况下，能够控制焦平面器件小于35℃。满足焦平面器件设计要求。

Abstract

In order to realize the thermal control of high-power focal plane apparatus (FPA)

the thermal design of FPA is studied based on the method of simulation and experiment according to the structure characteristics of the FPA. First of all

the main requirements of the thermal design of high-power focal plane apparatus are introduced and the feature of thermal design of focal plane assembly was analyzed. Then

the thermal performance is simulated by means of code TMG. The thermal test is conducted and the fit curve of temperature of FPA according to the thermal test is given. Finally

how to choosing the thermal control mode rationally is put forward according to thermal design example. The results show that the temperature of 50W high-power FPA can be controlled lower than 35℃ when it is worked in 2 minutes continuously and have the 12℃ cool source. It can meet the design requirements of FPA.
