空间用辐射式热控百叶窗的设计

Design of Thermal Louvers for Space Applications Based on Radiation Heat Exchange

在航天工业中,空间用百叶窗作为卫星的一种高效温度控制装置已经获得了广泛的认可。介绍了该系统的工作原理,详细描述了结构设计以及功能的实现,并对热控百叶窗模型进行性能分析。空间用百叶窗的有效温度控制是通过可转动叶片覆盖于辐射基板之上以改变有效辐射面积来调整辐射热量的方式实现的。本文设计的热控百叶窗作为星载超高光谱分辨率红外光谱仪的温控系统的一部分,旨在实现其外围温控。

Thermal louvers have gained wide acceptance as efficient devices for spacecraft＇s thermal control. Rotate shutters over a radiating surface to change the effective radiating area to achieve the thermal regulation. The design of thermal louvers, function realization and performance analysis are introduced. As part of the thermal control system of the Space-borne Spectrometer, the design aims to achieve the temperature control peripherally.
