摘要

摘要: 为了保证空间光学遥感器所需温度条件,本着被动热控为主、主动热控为辅的原则对其进行了热设计。首先,分析了遥感器在轨工作模式,建立了遥感器外热流计算模型,根据遥感器各面外热流变化,确定了3个极端工况。然后,以对日低温工况热设计为主对遥感器进行了热设计。最后,对热设计进行了热仿真分析和热试验验证。结果表明:镜组温度水平可控制在(181.5) ℃,且满足轴向温差要求;CCD器件温度变化为18~26 ℃,相邻轨道无温度累加。该热控设计方案可行,可对其它低能量、大窗口空间光学遥感器的热设计提供借鉴。

Abstract: In order to maintain the temperature of a space optical remote sensor in orbit, a thermal control system was designed according to a thermal control strategy that was based on the passive thermal control and aided with the active thermal control. Firstly, based on the work patterns of the space optical remote sensor, a modal for its flux calculation was established. Three extreme conditions were confirmed after analysis on the thermal flux and temperature boundary conditions of the sensor. Then, thermal design was concentrated on the sun-oriented work pattern in a low-temperature condition primarily. Finally, the thermal simulation and thermal test for thermal control system were performed. Simulation and test results show that the temperature fluctuations of mirrors are at (181.5) ℃ and the axis temperature difference meets the requirements of the optical system. The temperature of CCD device can be controlled between 18 ℃ and 26 ℃. The results demonstrate that the thermal design is feasible and these experiments can provide a reference for the thermal design of other optical remote sensors with low energies and big optical windows.
