The　heat　pipe　is　an　efficient　heat　transfer　device.　It　has　good　application　prospects　in　superconducting　magnet　cooling　and　space　cryogenic　heat　transfer　technology.　The　experimental　investigation　is　described　concerning　the　heat　transport　characteristics　of　a　thermosyphon.　The　results　show　that　the　heat　transfer　performances　of　the　thermosyphon　has　the　advantage　of　copper　solid　conductor　with　the　same　volume.　The　thermosyphon　could　be　used　to　cool　down　the　superconducting　magnet　more　quickly.
