摘要: 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.Abstract: Space Science Experiment Platform is an integrated platform which can provide a suitable operating environment for the payload. The integrated platform mainly contains mechanical system, thermal control system, electronic system, and communication system. Forced air cooling is a principal method by using air as heat transfer medium of the integrated platform. In order to reduce the flow resistance of ventilation circuit and increase the air flow, three wind duct layouts of the distributed ventilation cooling circuit were designed. Meanwhile, by using Computational Fluid Dynamics (CFD) method, the pressure fields and velocity fields of these three wind duct layouts were calculated, and the system resistance and velocity distribution were also obtained. By trading-off the structures and the flow field resistance characters of three distributed air loop layouts, the optimized result of the distributed air loop in Space Science Experiment Platform was produced.
