Résumé

This paper describes titanium heat pipe design, manufacture and tests. The heat pipes developed are a titanium-ammonia fixed conductance heat pipe(FCHP) with axial grooves and a titanium-ammonia-gas loaded variable conductance heat pipe with a heated reservoir (VCHP). Nitrogen was charged to VCHP as a non-condensible gas. The manufacturing processes in this heat pipe development program were studied successfully, and it has been clarified that titanium is very desirable as heat pipe material for use in space.
