摘要： PURPOSE: To improve cooling of air-cooled generator means by using a heat pipe as a heat sink contacting the generator. CONSTITUTION: Heat generated from a power module 1 transmits a heat pipe 11 to raise the temp. of the contact portion of the pipe 11 with a power module 1 while the temp. of a portion exposed to air such as a portion contacting the fins 15 lowers. Based on such a temp. difference, an operating fluid 13 evaporates at a high temp. Portion in the pipe 11 and resulting vapor discharges the heat at a lower temp. portion to condense. Because of this heat transfer resistance is negligibly small, the heat pipe 11 acts as a radiation plane on the whole if having a greatly larger area than the junction area of the pipe 11 and power module 1 using the pipe 11 as a heat sink 10. This enhances the air-cooling.

摘要： PURPOSE:To supply recirculating liquid in the shape of liquid film on the whole of a heating section and secure uniform temperature property, by a method wherein a hopper type liquid collecting section, having vent holes for passing the vapor of operating fluid, is attached to the intermediate part of a heat pipe provided with the axial heating section at the center of the lower end thereof so that the liquid collecting section is contacted closely with the internal peripheral surface of the heat pipe. CONSTITUTION:A heating section 12 heats operating fluid 11 and the vapor of the fluid 11 flows upward through the vent holes 16 of a liquid collecting section 13 to dissipate heat at the upper end of a sealed pipe 10 and transport heat. The condensed operating fluid 11 flows down along the inner wall surface of the sealed pipe 10 by gravity while being guided by the slant surface 15 of the liquid collecting section 13 and drops through a flow-down hole 14. The operating fluid will never flow into the vent holes 16 by the existence of a flange 17. According to this constitution, the recirculating operating fluid 11 is supplied on the whole of the surface of the heating section 12 from the upper end of the same.

摘要： PURPOSE:To heat the whole area of a diseased part organization and to remedy it by having plural heat pipes whose tips are pointed so as to be inserted to the diseased part, a thermal source to heat the rear edge sides of the heat pipes, a controller to control the temperature of the thermal source, and a temperature sensor to measure the temperature of the diseased part. CONSTITUTION:For three heat pipes 2 of a thermotherapy device 1, respective heat pipes 2 are inserted into a diseased part organization A1 so as to cause the center of three heat pipes 2 to be located on the approximately center of a tumor. A needle temperature sensor 6 is inserted beforehand so as to measure each internal temperature in a position made into the middle of two adjoining heat pipes 2 and 2. When a heater 3b of a thermal source part 3 is made exothermic by executing a current flowing, the heat generated by the heater 3b is made into the latent heat of an operating fluid by each heat pipe 2, the heat is transferred to a tip part 2a, it is radiated at the time of condensing it at the tip part 2a, and the diseased part organization A1 is heated from an internal part. When a low temperature part is detected except in the position of the needle temperature sensor 6, a thermotherapy is executed by increasing the exothermic quantity of the thermal source part 3 by a controller so as to make even the temperature at such a part into a set temperature or above.

摘要： PURPOSE:To enable holding of a heat transport amount at a specified value through arbitrary regulation of the heat transport amount by a method wherein an inner mov ing body is moved according to movement of a magnetic field produced by an outer derivative in a state that two compartments into which the interior of a container is partitioned are intercommunicated through a steel passage. CONSTITUTION:A closed magnetic circuit is formed, and an inner moving body 13 and an outer derivative 15 are attracted to each other. Since working liquid steam in a heat pipe 11 can flow through a steam passage hole 13c between a condensing part B and a second condensing chamber B2, the inner moving body 13 follows the derivative 15 smoothly and rapidly. When the outer derivative 15 is slid in a direction in which it is separated away from a vaporizing part A, the inner moving body 13 follows, and simultaneously with the increase of the effective volume of the condesing part B, an effective heat dissipating area is increased to improve heat transport capac ity. Conversely, when the outer derivative 15 is moved in a direction in which it approaches the vaporizing part A, heat transport capacity is decreased. This constitu tion rapidly regulates a heat transport amount of a heat pipe 11, and enables securing of the derivative 15.

摘要： PURPOSE:To obtain a loop type heat pipe capable of controlling the amount of transported heat correctly and simply, by a method wherein a condensing section is provided with a liquid reservoir capable of reserving the whole amount of liquid phase operating fluid at the lower side thereof while the liquid reservoir is provided with a liquid flow rate control valve and an opening and closing valve at the outflow side thereof. CONSTITUTION:In a loop type heat pipe, circulating flow causing the evaporation and condensation of operating fluid is generated when an opening and closing valve 10 is closed and operating liquid is supplied from a reservoir 6 into an evaporating section 1. When the opening and closing valve 10 is closed, the operating liquid is not supplied to the evaporating section 1, therefore, the evaporating section 1 is dried out and the transportation of heat is not effected. When the opening and closing valve 10 is opened fully, the flow rate of the operating liquid for the evaporating section 1 is controlled by a liquid flow rate control valve 7 whereby type transportation of heat in accordance with the amount of the operating liquid supplied to the evaporating section 1 is generated. In this case, the control valve 7 regulates the flow rate of the liquid phase operating fluid supplied to the evaporating section 1, therefore, correct flow rate regulation may be effected and, accordingly, the amount of transported heat may be controlled correctly.

摘要： PURPOSE:To improve the thermal properties of a heat pipe by feeding a wound tape, forming a wick layer on one surface of the tape and then working the tape into a pipe shape. CONSTITUTION:A coiled metallic tape 1 of copper, aluminum, iron stainless steel, etc., is fed out of a feeder. Wick material 2 is made mainly of inorganic or organic fiber as a tape in the shape of net, woven or non-woven fabric and fed at the same speed as the metallic tape 1 under the state coiled on the feeder. The wick material is stuck on one surface of the metallic tape 1 to form a wick layer 21. At this time, adhesives 23 are injected from a nozzle 22 on the metallic tape 1. Then, the metallic tape 1 is formed in the shape of a pipe so that the wick layer 21 comes inside the tape and the seam 10 is welded. The deformation due to working which may happen thereafter has no effect on the adhesion of the wick layer 21.

摘要： PURPOSE:To improve heat transport capacity, by a method wherein a radially extended-through slit part communicating with a space part between the outer surface of a wire gauge at a first layer and the inner wall surface of a closed pipe is formed in the wire gauge at a first layer, and a vent passage communicating from the slit part to a steam passage is formed in a wire gauge at other layer. CONSTITUTION:Air bubbles of working fluid generated by means of a heat input from the outside pass through the meshes of a wick 12, a slit part 13, and a vent passage 14 and escape in a steam passage 16. After passage of air bubbles, not escaping after passing through the wick 12 and grown to some extent of a grain size, to the slit part 13, the air bubbles escape through the slit part 13 and the passage 14 to the steam passage 16. Thus, since the inner wall surface of the closed pipe 10, imparting and receiving heat directly to and from the working fluid, is prevented from being covered with air bubbles, normally excellent transfer of a heat to the working fluid is performed. As a result, a heat flux can be increased.

摘要： PURPOSE:To hasten the melting of the working fluid in heat pipes and the startup of a heat exchanger by a method wherein at a partition wall between a flow passage for a high temp. fluid and a flow passage for a low temp. fluid, tubes with bottoms opening at the side of the flow passage for the high temp. fluid and projecting at the side of the flow passage for the low temp. fluid are placed and heat pipes are able to be inserted into and pulled out from the tubes with the bottoms at the side of the flow passage for the high temp. fluid. CONSTITUTION:A main flow passage 2 for a high temp. fluid and an auxiliary flow passage 3 for a low temp. fluid are partitioned by a partition wall 6 where through holes 5 are formed and the passage 2 and a flow passage for a low temp. fluid are partitioned by a partition wall 7. Tubes 8 are arranged at the wall 7 and one ends of the tubes 8 are opened at the side of the passage 2 and penetrate through the wall 7 and are fixed and the other ends are fixed to the side wall of a mainbody 1 and closed. When the working fluid in the pipes 9 is solidified at the time of startup, each pipe 9 is moved rearwards and located at the passages 2 and 3 to melt the working fluid. Then, the tip parts of the pipes 9 are inserted into the tubes 8. The vapor of the working fluid flows to the tip parts and provides heat to low temp. fluid C and is condensed and mediates heat exchange between a high temp. fluid H and the fluid C.

摘要： PURPOSE:To miniaturize the heat exchanger and to improve the reliability thereof by disposing dual pipes within a shell through which a first fluid is caused to flow, using the outer peripheral side part of the dual pipe as a heat pipe and causing a second fluid to circulate through the central part side part. CONSTITUTION:A plurality of dual pipes 24 are provided to penetrate through a shell 20 through which a high-temperature fluid such as liquid sodium or the like is circulated, and a condensible working fluid 28 is sealed between an outer pipe 25 of each of the dual pipes 24 and an inner pipe 27 thereof through which a low-temperature fluid 26 such as water flows. A wire 29 made of wire nets or the like is arranged on the inner peripheral surface of the outer pipe 25 to form a heat pipe 30, and inner pipes 27 are connected to each other by a bent pipe 33 to form a zigzag pipe. Thus, both inner and outer sides of the dual pipe 24 serve as a heat absorbing part and a heat radiating part. Therefore, the entire constitution of the heat exchanger can be miniaturized. Furthermore, since a heat pipe 30 is interposed between first and second fluids 21 and 26, even if there are defects such as pinholes or the like in the inner pipe 27, both fluids do not immediately come into contact with each other. Further, by measuring the pressure of a working fluid 28, these defects can be immediately detected.
