摘要： PURPOSE: To permit heat transfer from a local heat generating source efficiently by a method wherein a container is formed of a flat heating unit, a heat dissipating unit, apart from the heating unit upwardly and having an area wider than that of the heating unit, and a side wall unit, communicating mutually the peripheral rim parts of said units across the whole periphery thereof, so as to have a hollow and flat shape. CONSTITUTION: The vapor of operating fluid transfers the generating heat of a CPU as the latent heat of evaporation while the heat is dissipated in a heat dissipating unit 12b when the vapor is condensed. In a heat pipe 11, the heat dissipating unit 12b is formed so that the area of the same is four times of that of a heating unit 12a whereby the contacting rate of the vapor of operating fluid, moved to the heating unit 12a, with the internal surface of the heat dissipating unit 12b at a low temperature is increased to four times compared with a conventional device. Accordingly, big amount of vapor can be condensed whereby heat transfer capacity is increased and prominent cooling performance can be developed against the big amount of heat generation in the CPU while the overheating of the CPU can be prevented surely.

摘要： PURPOSE:To enable the heat transportation of a long distance without requiring any external power or enable heat transportation under a top heat mode and improve the heat recovering efficiency by a method wherein a part of heat to be recovered is changed into a power to circulate the operating liquid of a heat pipe forcedly utilizing the power. CONSTITUTION:Operating fluid 12, liquefied in the end section of the side of a heat exchanger 10 or in a condensing section, flows into a circulating tube 11, opened in the condensing section. A pump 13, interposed in the circulating tube 11, is operated by receiving a driving force from a turbine 7 and circulates the liquid phase operating fluid 12 in the condensing section forcedly to the end section of a heat accumulating body 4 or an evaporating unit. Accordingly, the pump 13 pumps up the operating liquid even when the condensing section is installed at a position lower than the evaporating unit or the distance between the evaporating unit and the condensing section is long, whereby heat can be transported continuously. Further, the heat recovering efficiency can be improved since an external energy is not consumed.

摘要： PURPOSE:To provide a small-sized cooling apparatus capable of uniform cooling the inside of a conduit passage for electric power transmission over a long distance of the same. CONSTITUTION:A heat pipe 10 absorbs heat in a conduit passage 2, so that a title apparatus is made small-sized and there is ensured uniform heat absorption longitudinally of the cavity passage 2. Further, a looped heat pipe is employed, so that there are prevented a working fluid liquefied in a condensation section 12 and flown back toward an evaporation tube 11 and a vapor stream of the working fluid moving from the evaporation tube 11 to the condensation part 12 from interferring to each other to ensure long distance reflux flow and hence a sufficient amount of the working fluid is supplied to the evaporation tube 11. Additionally, a circulation pump 20 is used for movement of the working fluid to the evaporation tube 11 for forced circulation of the working fluid, so that even further long distance reflux of the working fluid is facilitated. Thus, cooling in the conduit passage 2 over a long distance is ensured using the present heat pipe 10.

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 measure temperatures of each part easily and precisely by axially inserting a large number of superfine fibers including optical fibers into a heat pipe, and causing the optical fibers to protrude from the pipe to measure temperatures based on the intensity of Raman scattered light. CONSTITUTION:A large number of superfine fibers 2 including optical fibers serve as wicks to effect rapid reflux of liquid phase operation fluid. The end of an optical fiber out of these superfine fibers 2 is drawn out of a closed pipe 1 to be connected to a measuring instrument 6 so that light pulses are sent into the optical fiber 3 and at the same time temperatures are measured based on the intensity of reflected light due to Raman scattering, in which the position of the temperatures are determined based on the period from the incidence of light pulses until the return of Raman scattered light. As a result, the temperature distribution over the entire length of the heat pipe can be measured without discontinuance, and since the optical fiber serves as a wick, temperature distribution can be measured at any time.
