摘　　要：近些年,以立方星为代表的纳卫星发展迅速,数年来立方星发射总数已达上千颗。立方星集成度高,空间和能源有限,立方星热设计变得尤为重要。该文针对上科大二号A星,阐述立方星任务典型的非保守式热控设计。在轨遥测数据分析表明该星热控设计合理,星上环境温度满足星上单机要求,为立方星的热控设计提供技术借鉴。Recent years,nanosatellite represented by CubeSat develops rapidly.For many years,over 1000 CubeSats were launched into the space successfully.Due to high-integrated feature as well as the dimension and power constrains,thermal design for CubeSat is one of key technologies.Thus,in the present paper,a non-conservative thermal design was given to serve to STU-2A CubeSat.Telemetry data analysis in orbit indicated that the non-conservative thermal design is reasonable,the temperature environment could meet the thermal requirements for the satellite components,it is a valuable technology reference for CubeSat thermal design.
