摘要： PURPOSE:To improve response to heat upon starting by a method wherein operating liquid is made to flow out of a second liquid returning tube upon starting and, thereafter, the operating liquid is sprayed against the inner surface of a sealed tube from a first liquid returning tube provided at the inside of the sealed tube. CONSTITUTION:When a second opening and closing valve 10 is opened to conduct operating liquid 12 in a condensing unit 6 along the inner surface of a sealed tube 2 from a second liquid returning tube 11 upon starting heat collection, the wall surface temperature of an evaporating unit 4 is reduced. On the other hand, the vapor of the operating liquid, which is generated in the evaporating unit 4, provides a heat exchanging coil 5 with heat and is condensed whereby the vapor outputs heat in the form of hot-water or the like. After the wall surface temperature of the evaporating unit 4 is reduced in some degree in such a manner, the first opening and closing valve 9 is opened and the second opening and closing valve 10 is closed to spray the operating liquid 12 against the wall surface of the evaporating unit 4 from the small holes 8 of a first liquid returning tube 7. In this case, the wall surface can be wetted uniformly and the generation of evaporation is facilitated since the temperature of the wall surface is low. When the starting operation of the title syphon is effected in accordance with the above-described program, evaporation can be effected energetically and, thereafter, the operating liquid 12 is sprayed against the wall surface of the evaporating unit 4 whereby the generating amount of vapor upon starting is ample and response to heat is improved.

摘要： PURPOSE:To provide a superior work efficiency and a superior thermal transportation amount by a method wherein an inner pipe having an opened upper end and having several air holes at its circumferential wall is concentrically inserted and arranged within an external pipe having a closed structure and a helical line is held between both pipes. CONSTITUTION:A heat Q is applied to an evaporater part 15 from an external source and the heat Q is retrieved from a radiation part 14, a working fluid 19 is evaporated and gasified at an evaporation part and its steam flows upwardly toward a radiation part 14 having a low pressure. In this case, the working fluid vapor is generated between the inner pipe 11 and the outer pipe 10 to generate an ascending flow. Since a helical line 12 is held between the pipes, a flowing resistance is high, resulting in that the working fluid vapor passes through air holes 17 formed in the inner pipe 11, enters the inner pie 11 and then flows toward the radiation part 14. In this way, the condensed and liquefied liquid phase working fluid in contact with an inner circumferential surface of the outer pipe 10 at the radiation part 14 flows down along the inner surface of the outer pipe 10, enters a space between the inner pipe 11 and the outer pipe 10, the working liquid becomes a helical flow due to a presence of the helical line 12 and flows out of the inner pipe 11. Therefore, the interior of the inner pipe 11 becomes a vapor passage and the outer part becomes a working fluid passage and thus a gas liquid separation is carried out.

摘要： PURPOSE:To prevent dry out of a heat collecting surface, to increase a heat carrying amount, and to effect efficient recovery and fetching of a terrestrial heat, by a method wherein liquid phase working fluid is stored in a liquid reservoir part independently separated from a heat incoming spot, and is returned to a spot where heat incomes in a state in that the working fluid is isolated from a steam flow. CONSTITUTION:The temperature of a heat dissipation part 15 is set to a value lower than an underground temperature, and with a flow rate regulating valve 19 opened, working fluid 12 in a reservoir 14 is caused to outgo to a reflux distribution pipe 20, and the working fluid is injected toward the inner wall surface of a closed pipe 11. The liquid phase working fluid 12 is uniformly distributed and fed to the inner wall surface of the closed pipe 11, is vaporized and evaporated resulting from receipt of a terrestrial heat during flow down, and flows toward the heat dissipation part 15. The liquid phase working fluid 12 is fed directly to a spot in the vicinity of the inner wall surface of the closed pipe 11 through the reflux distribution piston 20, a section, where a convection flow is produced between a steam flow and the working fluid, is extremely shortened, and the working fluid is prevented from flying. The opening of a flow rate regulating value 19 is regulated so that an amount of the working fluid vaporized by a terrestrial heat becomes equal to an amount of the working fluid fed through the flux distributing pipe 20, and this regulation prevents a liquid column from being produced to the bottom part of the closed pipe 11, and permits the whole of the inner surface of the closed pipe 11, positioned to a heat absorbing part 13, to form the vaporizing surface of the working fluid.

摘要： PURPOSE:To prevent the elongation upon hanging by a method wherein the lower end of a heat pipe is inserted into a sheath body, braided by wire so as to have a reticulated shape, then, the upper end of the sheath body is fixed and the sheath body is pulled into axial direction to reduce the diameter of the sheath body and contact the same with the outside of the heat pipe closely. CONSTITUTION:A tubular sheath body 6 is formed by braiding a multitude of high-strength wires 6a so as to have a reticulated shape. The diameter of the sheath body 6 is designed so as to be slightly larger than the diameter of a heat pipe 2 and the evaporating section 2a of the continuous heat pipe 2 is inserted into the sheath body 6. Subsequently, the upper end of the sheath body 6 is retained to a fixing trestle 4 on the ground and the sheath body 6 is suspended into the hole C in the ground under a condition that the sheath body 6 is supporting the heat pipe 2. Then, a tension force is exerted on the sheath body 6 due to a gravity including the heat pipe 2 whereby the sheath 6 is elongated and contracted, thereby contacting closely with the outer periphery of the evaporating section 2a and fixing the heat pipe under strongly wound condition.

摘要： PURPOSE:To obtain a loop type heat pipe capable of exhibiting its specified heat transferability with the arrangement of liquid return pipes kept properly. CONSTITUTION:Two or more liquid return pipes 14 arranged inside an evaporation pipe 12 are connected in a ring shape by ring-like positioning members 20 at specified lengthwise pitches to restrict the movement of the liquid return pipes 14 in the circumferential and radial directions of the evaporation pipe 12. Therefore, the arrangement of the liquid return pipes 14 is kept properly, and the working liquid is evenly supplied onto the inner face of the evaporation pipe 12, allowing a loop type heat pipe 11 to exhibit its specified heat transferability.

摘要： PURPOSE:To provide a method for manufacturing a liquid return pipe for a loop-shaped heat pipe in which the liquid return pipe can be mounted easily at a prescribed interval spirally inside an evaporation pipe. CONSTITUTION:In a forming process of a twisted body 17, a liquid return pipe 13 and an air-permeable interposition 14 to fill a gap between the liquid return pipes 13 are sent out simultaneously toward the outside of a spacer 15 which forms vaporstream in a central part of a evaporation pipe 12, and the liquid return pipe 13 and the interposition 14 are twisted spirally outside the spacer 15 to form the twisted body 17 which substantially has the same outer diameter as the inner diameter of the evaporation pipe 12. In an inserting process of the twisted body 17 into the evaporation pipe 12, only by inserting the twisted body 17 into the evaporation pipe 12, the liquid return pipe 13 can be mounted easily inside the evaporation pipe 12 at a prescribed interval.
