A long titanium‐water thermosyphon heat pipe was designed and tested in support of NASA’s lunar surface power system. With a ΔT of 11.6 C, a prototype has been shown to meet the temperature drop specification of 15 C at 400 W and 400 K. The heat pipe is designed to be embedded in a composite radiator panel to spread waste heat delivered by a circulating pumped loop. The major challenge was managing the fluid inventory to balance the conflicting requirements of power capacity and freeze‐thaw tolerance. A unique hybrid wick was designed to achieve the required thermal performance and yet store all the working fluid during idle periods in a freeze‐thaw tolerant fashion. A non‐condensable gas charge was used to boost power capacity at lower operating temperatures. Eighteen prototypes will be built and tested.
