摘　　要：空间科学实验平台是为突破单一化实验装置设计模式而研制的一种多用途空间科学实验平台.根据空间科学实验平台内气液回路设计的相关问题,给出了回路系统中主要设备的相关设计方法,包括循环风机、气-液换热器、冷板,并根据传热效率和系统安全性的考虑,对流体工质的选择提出建议.初步分析结果及国际类似研究证明,气液回路技术结合其他主动及被动热控制措施,可以很好地满足空间实验平台内部仪器设备及样本的不同温度控制要求.Space Science Experimental Platform（SSEP） is a multi-function experimental platform being developed as an alternative for traditional single-function experimental apparatus.This paper introduces the designs of heat transfer fluid loops in SSEP,and related design methods for some major equipment,including Avionics Air Assembly（AAA） fan,gas-liquid heat exchanger and cold plates.Suggestions for working fluid selection are also listed with the considerations of heat transfer efficiency and system safety.Preliminary analysis results,as well as the successful application of such designs in similar platforms developed by ESA and NASA,proved that fluid loop heat transfer technology,combined with complementary active and passive thermal control measures,can maintain the multi-function experimental platform and its payloads within their required temperature limits.
