“FLW”型辐射致冷器热力设计

The Thermodynamic Design of “FLW” Radiative Cooler

本文介绍按卫星工作条件及致冷器在卫星中安装位置而采用“W”形状被动式两级辐射致冷器进行热力设计。通过热力分析计算选择合理的几何设计尺寸及合适材料、工艺参数;并实际应用于“FLW-1”型设计。

The thermodynamic design of a passive two-stage“W”RadiativeCooler for a satellite is presented.The reasonable geometric size,appropriatematerial and technical parameters are chosen by a thermodynamic calculationand are applied to the design of“FLW-I”.
