<p><P>PROBLEM TO BE SOLVED: To provide a loop-type heat pipe capable of remarkably improving heat transportability in bottom heat and enlarging an operating temperature range, simple in structure and extremely high in productivity. <P>SOLUTION: An annular pipe 1 filled with heat medium liquid 11 in a pressure reduced state comprises a heat receiving pipe part 12 linked with a heating mechanism, at the lower part, and a heat radiating pipe part 13 at the upper part. The heat receiving pipe part 12 and the heat radiating pipe part 13 communicate with each other through lifting pipe parts 14a, 14b, and the heat medium liquid 11 can circulate in the annular pipe when receiving heat. The heat receiving pipe part 12 of the annular pipe 1 is provided with an upward swelling steam expansion chamber E, and air bubbles are continuously supplied to the rising pipe part 14a, while the heat radiating pipe part 13 is also formed with an upward swelling steam contraction chamber S. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
