摘要：

Good　starting　performance　is　essential　for　work　of　heat　pipe　operating　reliably.　Inclination　angle　is　one　of　the　influence　factors　to　starting　characteristics　of　thermosiphon.　A　sodium-potassium　(Na-K)　thermosiphon　consists　of　55%　potassium　and　45%　sodium　is　researched　to　evaluate　the　influences　of　heat　pipe　orientation　on　the　starting　characteristics.　The　starting　characteristics　at　six　different　angles　(0°,　10°,　20°,　30°,　40°　and　50°)　have　been　experimentally　investigated　and　the　wall　temperature　distribution　curve　is　portrayed.　The　experimental　results　indicate　that　the　Na-K　heat　pipe　has　good　startup　performance.　The　increase　of　the　inclination　angle　improves　the　temperature　of　the　condenser　and　conduces　to　the　startup　of　the　heat　pipe.　©　2014,　Science　Press.　All　right　reserved.
