摘　　要：针对我国高轨通信卫星不断提升的散热需求,提出采用基于高低温分区热管网络的热设计方法。在分析热管网络散热能力的基础上,进行设备分区布局设计、分区热管网络散热面设计和分区热管网络布局设计。该方法可在保证卫星仪器设备工作温度、不降低热设计可靠性、不增加分系统重量及功率需求的前提下,将卫星散热能力提升15%~20%。文章还结合近些年通信卫星研制中的经验和教训,归纳给出高低温分区热管网络设计中的注意事项,以期为相关工程设计提供有效指导。In response to the increasing heat dissipation needs of China’s GEO communication satellites,a thermal design method characterized by high-low temperature partition of heat-pipe network was proposed.Based on the analysis of heat-pipe network heat dissipation capability,the device partition layout design,the heat-pipe network cooling surface design,and the partition heat-pipe network layout design were carried out.With this method,the satellite’s heat dissipation capacity can be improved by 15%to 20%under the premise of ensuring the operating temperature of satellite equipment,not reducing the reliability of thermal design,and not increasing the weight and power requirements of subsystems.In addition,enlightened by the experience and lessons of communication satellite research in recent years,the points for attention in designing high-low temperature partition heat-pipe networks are summarized,to provide effective guidance for the related engineering design.
