Abstract

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.
