p style="line-height: 1.5em " span style="font-family: 宋体, SimSun "环路热管作为高效的相变传热装置,是卫星和航天飞行器在恒定温度下稳定长寿运行的关键部件,而毛细泵主芯是环路热管中最核心的部件之一。近日,我国首次在高分9号卫星上成功应用多孔陶瓷毛细泵主芯,这是多孔陶瓷作为我国自主研发的最新一代毛细泵主芯材料国际上首次应用于环路热管,其控温精度在国际上处于领先地位。/span/pp style="line-height: 1.5em "span

style="font-family: 宋体, SimSun " 高分九号卫星是国家高分辨率对地观测系统中一颗光学遥感卫星,地面像元分辨率最高可达亚米级,已经于近日成功发射。据报道由上海硅酸盐所研制的多孔陶瓷毛细主芯毛细孔径在0.1-10微米可调,最大毛细抽吸力达70KPa,渗透力强,与传统的金属毛细芯相比,多孔陶瓷毛细芯具有密度小、强度高、耐腐蚀、毛细力大以及热导率低等优点,可显著提高环路热管的稳定性和可靠性。安装陶瓷毛细泵主芯的环路热管与传统金属管相比,热源控温精度由(± 3℃)提高到(± 1℃),甚至更优,从而改善了空间相机的热平衡,将我国空间遥感器控温精度提升到新的高度,大幅度提高了相机的成像质量——亚米级,达到国际先进水平。/span/pp style="line-height: 1.5em "span style="font-family: 宋体, SimSun " /spanstrong style="font-family: 宋体, SimSun
