摘　　要：针对应用于空间核动力及大功率航天器的高温热排散技术,介绍了一种基于3D打印增材制造技术的钛水热管,满足100~300℃温区热量的远距离传输需求。该热管壳体及毛细芯结构通过3D打印技术一体成型,解决了中高温热管在制造方面的诸多难题。文章对热管的传热能力进行了理论分析,分析结果表明热管在180~250℃区间内传热能力最佳,同时搭建了热管启动以及传热能力的试验验证平台,对热管在水平以及逆重力姿态的传热能力进行了试验验证,并与理论分析结果进行了比较。试验结果表明:3D打印技术可成功应用于槽道热管的制造。该钛水热管后续将应用于航天器高温热排散系统的地面演示系统中,用于连接高温两相流体回路冷凝器和碳纤维材料辐射板。A 3 D-printing high-temperature titanium-water heat pipe(HP) is introduced in this paper. This HP can be applied in the high-temperature heat dissipation system of space nuclear power and high-power spacecraft, and transfer heat between 100~300℃. The shell and capillary structure of the HP are manufactured by 3 D printing technology, which can solve many difficulties of the high-temperature HPs. Theoretical analysis of the HP is carried out, which shows the heat transfer ability reaches the peak when the HP works between 180~250℃. An experimental system is established to verify the start-up and heat transfer ability of HPs at different anti-gravity attitudes. The results show that 3 D printing can be applied to manufacture HPs successfully. This HP will be integrated into a ground demonstration system of space high-temperature heat dissipation system to connect two-phase fluid system and carbon radiator.
