空间科学实验平台是集机械、热控、电子学及通信等系统于一体的综合平台,能够为有效载荷提供适宜的工作环境.为减小通风回路的流动阻力,提高空气流量及其散热能力,对采用强迫通风冷却散热方式的空间科学实验平台分布式风回路提出三种结构布局并进行对比.利用计算流体力学方法对三种布局的压力场和速度场进行了计算,得到空间科学实验平台内部阻力和速度分布.综合考虑三种布局的结构及流场阻力特性,得到空间科学实验平台分布式风回路的优化设计结果.
Space Science Experiment Platform is a comprehensive platform integrating mechanical, thermal control, electronics and communication systems, which can provide appropriate working environment for payload.In order to reduce the flow resistance of ventilation loop, increase the air flow and its heat dissipation capacity, Three structural layouts are proposed and compared for the distributed wind loop of space science experimental platform adopting forced ventilation cooling and cooling method.The pressure field and velocity field of the three layouts are calculated by using computational fluid dynamics method and the interior of space science experiment platform Resistance and velocity distribution.According to the structure of the three layouts and the resistance characteristics of the flow field, the optimal design results of the distributed wind loop of the space science experimental platform are obtained.
