PURPOSE:To enable efficient heat transmission, by sucking up mechanically a condensed liquid generated at a low place, in a thermal siphon type heat pipe. CONSTITUTION:A heat transmission device 10 is manufactured, for example, by making a copper pipe 11 into the subject, a heating part 21 at its high place is welded to a heat collecting panel 2 of a solar water heater on the roof by making the heat transmissibility favorable and a cooling part 31 at a low part is inserted into the bottom part of water of an indoor hot water tank 3. A working fluid (for example, water) evaporated by the heating part 21 is arrived at the condensing part 31, streams down through a part 102 by liquidizing here and collected within a collecting area 103 provided on the lower part of the copper part 11. The liquid collected here is sucked in by a mechanical pump 16, which is pumped up to the required high place 121 in the copper pipe 11 by a liquid feed pipe 12 connected with a discharge opening 122. The liquid discharged to the high place 121 is dropped within the heating part 21 through a part 101 by gravity, which is re-evaporated here and heat is transferred continuously by repeating the above process. |
