Embodiment 1 FIG.
A heat pipe in which a working fluid and a non-condensable gas are enclosed is known as a variable conductance heat pipe having a temperature adjustment function so as to have a specific operating temperature.

  The non-condensable gas is, for example, nitrogen gas or argon gas, and the working fluid is, for example, water or alcohol. In the operating temperature range of the heat pipe, the working fluid in the pipe exists as a liquid and its vapor, and the non-condensable gas exists mainly in a gaseous state. When water is used as the working fluid, degassed pure water is preferably sealed.

  FIG. 1 is a configuration diagram of a gas-liquid sealing apparatus according to Embodiment 1 of the present invention. FIG. 1 is a view in which a pipe 19 serving as a heat pipe is attached. As shown in FIG. 1, a hydraulic fluid supply unit 52 that supplies hydraulic fluid, a non-condensable gas supply unit 24 that supplies non-condensable gas, a vacuum exhaust unit 23, and a sealing processing unit 20 that seals the pipe 19. In addition, the hydraulic fluid supply unit 52, the non-condensable gas supply unit 24, and the vacuum exhaust unit 23 are connected via pipes, and the connection unit 34 that directly connects the pipe 19 is provided.

  The connection unit 34 includes a first connection port 66 for connecting the pipe 19, a second connection port 67 for connecting the hydraulic fluid supply unit 52 via the pipe 38, and a non-condensable gas supply unit via the pipe 28. And a fourth connection port 69 for connecting the vacuum exhaust part 23 via the pipe 32. A first connection port 66 for connecting the pipe 19 is provided below the connection portion 34, and a second connection port 67 for connecting the hydraulic fluid supply unit 52 is provided above the first connection port 66, and the hydraulic fluid supply unit By providing 52 above the second connection port 67, the fluid can be smoothly supplied using gravity.

  Valves 35 and 37 are provided in the piping 38 between the hydraulic fluid supply unit 52 and the connection unit 34, and an orifice 36 is provided between the valves 35 and 37.

  Valves 25 and 27 are provided in the middle of the pipe 28 between the non-condensable gas supply unit 24 and the connection unit 34, and a pressure gauge 26 is provided between the valves 25 and 27.

  A valve 30, 31, 33 and a vacuum pressure gauge 22 between the valves 33, 31 are provided in the middle of the pipe 32 between the vacuum exhaust part 23 and the connection part 34, and a low temperature trap 29 is provided between the valves 31, 33. Is provided.

  The connecting portion 34 may be constituted by an integral member, or may be constituted by combining a plurality of pipes and connecting members instead of an integral member.

  The pipe 19 has a structure in which one end is opened and the other end is closed, and the opened one end is detachably connected to the connection port 66 of the connection portion 34. Further, the connecting portion 34 and the pipe 19 are sealed with the sealing material 21 at the first connection port 66. For the sealing material 21, for example, an O-ring is used. If the connecting portion 34 and the pipe 19 can be easily attached and detached, other sealing members such as a vacuum tube made of an elastic material may be used instead of the O-ring, for example.

  As the non-condensable gas supply unit 24, a container in which the pressure of the non-condensable gas is controlled or a device that sends out a certain amount of non-condensable gas can be used. For example, a container whose pressure is controlled is a gas cylinder of non-condensable gas, and a device that sends out a certain amount of non-condensable gas is an amount of gas flowing into the container when an exhaust pump, a pressure gauge, etc. are connected to the container. And the exhaust gas are adjusted so that the pressure in the container of the non-condensable gas is adjusted to a predetermined pressure.

  The sealing processing unit 20 seals the opening side of the pipe 19 connected to the first connection port 66 at a sealing position below the first connection port 66. The sealing device 20 closes one end opened by caulking a copper tube or another metal tube to the pipe 19, for example. Further, by providing a valve between the first connection port 66 and the pipe 19, it is possible to separate the gas-liquid sealing and the sealing work.

  The vacuum exhaust part 23 is a vacuum pump such as a rotary pump. The valves 30 and 31 are for vacuum shut-off for protecting the low temperature trap 29 when the vacuum exhaust part 23 is stopped.

  Next, a gas-liquid sealing method using the gas-liquid sealing apparatus having the above configuration will be described. First, the pipe 19 is fixed to the first connection port 66 below the connection portion 34 with the sealing material 21. Next, the valves 25, 33 and 35 are closed, the valves 30 and 31 are opened, and the low temperature trap 29 is operated. When the pressure of the vacuum pressure gauge 22 becomes a desired pressure or less (0.6 Pa or less when the working fluid is water or alcohol), the valve 33 is opened, the inside of the pipe 19 is evacuated, and the vacuum pressure gauge 22 When the pressure falls below the desired pressure, the valve 33 is closed. Thereafter, the valve 37 is opened, the working fluid is filled in the orifice 36, the opening time of the valve 35 is opened for a time corresponding to the diameter of the orifice 36 and the amount of working fluid injected, and the working fluid is introduced into the pipe 19. Inject. Next, the valve 25 is opened, and the non-condensable gas is allowed to flow from the non-condensable gas supply section 24 into the pipe 19 through the pipe 28 and the connection section 34 which are non-condensable gas supply paths. The pressure of the non-condensable gas supplied is higher than the vapor pressure of the working fluid. Further, the volume of the container for storing the non-condensable gas in the non-condensable gas supply unit 24 is made sufficiently larger than the volume in the connection part 34 and the pipe 19, and the non-condensable property of a predetermined pressure is set in the container. By storing the gas and opening the valve 25 when supplying the gas, the pressure in the connection portion 34 and the pipe 19 is approximately the pressure of the non-condensable gas supply portion 24. By setting the pressure to the set pressure, the non-condensable gas pressure in the pipe 19 can be easily set to the set pressure. Also, a non-condensable gas having a set pressure can be supplied into the pipe 19 by a method of supplying a fixed amount of gas calculated from the volume in the connecting portion 34 and the pipe 19 and the set pressure.

  After supplying the non-condensable gas, the valve 25 is closed. Next, the pipe 19 is sealed by the sealing processing unit 20. The pipe 19 may be cut at the sealing position at the time of sealing. After sealing, the pipe 19 or the cut end of the pipe 19 is removed from the connecting portion 34. In addition, when sealing is applied by a combination of ultrasonic caulking and brazing, soldering, welding, or a combination of plastic caulking and brazing, soldering, welding, etc., the hermeticity of the sealing portion may be improved. it can.

  As described above, according to the gas-liquid sealing device of the first embodiment, since the piping system and the pipe 19 need only be evacuated, the evacuation can be performed in a short time and the production efficiency can be improved. . Further, even if the heat pipe is small, such as a pipe diameter of 10 mm or less and a working fluid filling amount of 10 cc or less, the opening of the valve 35 is opened only for a time corresponding to the diameter of the orifice 36 and the amount of working fluid injected. By controlling the time, the amount of hydraulic fluid injected into the pipe 19 can be accurately controlled, and the non-condensable gas is piped from a container whose internal non-condensable gas pressure is controlled to a set pressure. Therefore, the pressure of the non-condensable gas in the pipe 19 can be made accurate. Depending on the amount of hydraulic fluid filled, the valve 35 or the valve 37 can be assumed to be a kind of orifice, and the orifice 36 can be omitted.

  Further, by making the inner surface of the hydraulic fluid intrusion path 38 to the pipe 19 including the orifice 36, the valves 35 and 37, and the connection portion 34 liquid repellent with respect to the hydraulic fluid, adhesion of the hydraulic fluid is prevented. The amount of the remaining working fluid can be drastically reduced, and the evacuation time in the next process can be shortened. For each part of the intrusion route, a liquid repellent resin may be used, or a material subjected to a liquid repellent coating process may be used. For example, when the hydraulic fluid is water, a water-repellent resin material such as ethylene tetrafluoride or polyethylene or a material obtained by coating a metal tube or resin tube with a water-repellent resin material is used.

  Further, in order to make the liquid repellency, it is necessary to make the direction of flow of the working fluid the direction of gravity, but the internal surface area around the connection portion 34 is reduced, and the internal surface area inside the connection portion 34 is reduced. Thus, when the amount of the working fluid attached is reduced, the flow of the working fluid is made lyophilic with respect to the working fluid at the peripheral portion of the connecting portion 34 and the inner surface of the connecting portion 34 into which the working fluid enters. In addition, the degree of freedom can be given to the direction in which the hydraulic fluid flows. As the material of the periphery of the connecting portion 34 and the connecting portion 34, a material having good lyophilicity with respect to the working fluid or a material that has been subjected to lyophilic coating treatment is used. For example, when the hydraulic fluid is water, a material with good hydrophilicity is used for the peripheral part of the connection part 34 and the connection part 34, or a material obtained by oxidizing the inside of the metal tube. As a result, the hydraulic fluid flows easily, and the amount of the hydraulic fluid enclosed can be stabilized.

  In addition, FIG. 1 shows an example in which one first connection port 66 is provided in the connection part 34, but by providing a plurality of pipes 19 and simultaneously sealing a plurality of pipes 19, the production efficiency of the heat pipe is further increased. Can be improved.

Are connected.

  As in the first embodiment, a working liquid and a non-condensable gas are sealed in the pipe 19. Next, the sealed pipe 19 is removed from the first connection port 66. Next, the valve 39 is closed, the valves 35 and 37 are opened, the valve 40 is opened, and the operation that remains attached to the piping 38, the valves 35 and 37, the orifice 36, and the connecting portion 34, which are the hydraulic fluid supply path. Blow off the liquid. As a result, the residual hydraulic fluid in the pipe 38 path can be reduced and the evacuation time in the next process can be shortened, so that the production efficiency can be improved. Further, in the above work flow, the opening and closing of the valves 35, 37, 39, 40 is automated by sequence control, so that the working time can be further shortened.

  FIG. 3 is based on the configuration of the first embodiment. The difference from FIG. 2 is that the connection position of the nitrogen gas blow part 41 is a pipe part on the connection part 34 side from the orifice 36. A three-way valve 70 is provided between the second connection port 67 and the valve 35, and the nitrogen gas blow part 41 is connected to the three-way valve 70 through the valve 40.

  As in the first embodiment, a working liquid and a non-condensable gas are sealed in the pipe 19. Next, the sealed pipe 19 is removed from the connection port 66. Next, the valve 37 is closed, the valve 40 and the three-way valve 70 are opened, and the working fluid that adheres mainly to the connection portion 34 and its periphery is blown off. Thereby, the residual hydraulic fluid in the piping path can be reduced, the evacuation time in the next process can be shortened, and the production efficiency can be improved. Further, the flow of the above work can be further shortened by automating the opening and closing of the valve 40 and the three-way valve 70 by sequence control, as in FIG.

Embodiment 3 FIG.
4 and 5 are configuration diagrams of the gas-liquid sealing device according to Embodiment 3 of the present invention. FIG. 4 is based on the configuration of the first embodiment, and a valve 39 is provided between the valve 37 above the orifice 36 and the hydraulic fluid supply unit 52, and the hydraulic fluid supply unit 52 has a pressure adjustment valve 54. A non-condensable gas pressurizing unit 53, a vacuum exhaust unit 42 for degassing and hydraulic fluid replenishment, and a hydraulic fluid replenishing tank 48 are provided. The degassing and hydraulic fluid replenishing vacuum exhaust section 42 is connected to a hydraulic fluid supply section 52 via a valve 49, and the hydraulic fluid supplement tank 48 is connected to a hydraulic fluid supply section 52 via a valve 50.

  Similarly to the vacuum exhaust unit 23, the vacuum exhaust unit 42 for degassing and hydraulic fluid replenishment is a vacuum pump such as a rotary pump. A vacuum pressure gauge 47 and a low temperature trap 44 are connected in order from the valve 49 side to the piping 46 path between the vacuum exhausting part 42 for degassing and hydraulic fluid replenishment and the valve 49. The low temperature trap 44 is a vacuum shutoff valve for protecting the low temperature trap 44 when the degassing and working fluid replenishing vacuum exhaust section 42 is stopped on the degassing and working fluid replenishing vacuum exhaust section 42 side and the valve 49 side. 43 and 45 are provided.

  The gas-liquid sealing method using the gas-liquid sealing device is basically the same as in the first embodiment, but the hydraulic fluid can be degassed and replenished, and the hydraulic fluid in the hydraulic fluid supply unit 52 can be used. Back pressure can be applied. For example, the valves 49, 45 and 43 are closed and the cold trap 44 is activated. When the low temperature trap 44 reaches a predetermined temperature, the degassing and hydraulic fluid replenishing vacuum exhaust section 42 is operated, and then the valves 43 and 45 are opened. When the vacuum pressure gauge 47 falls below a predetermined pressure, the valve 49 is opened and the hydraulic fluid supply unit 52 is evacuated. Thereby, the dissolved gas in the hydraulic fluid in the hydraulic fluid supply unit 52 can be vacuum degassed. When the valve 50 is opened, the hydraulic fluid is supplied from the hydraulic fluid replenishment tank 48 to the hydraulic fluid supply unit 52.

  Further, after evacuating the hydraulic fluid supply unit 52 and confirming that the valves 49 and 50 are closed, the valve 51 is opened so that the non-condensable gas is supplied from the non-condensable gas pressurizing unit 53. The back pressure can be applied by the non-condensable gas to the working fluid in the working fluid supply unit 52, and the working fluid is reliably injected into the pipe 19 from the orifice 36.

  FIG. 5 is based on the configuration of the first embodiment. The difference from FIG. 4 is that the hydraulic fluid temperature controller 55 is provided in the hydraulic fluid supplier 52. The hydraulic fluid temperature control unit 55 sets the hydraulic fluid temperature in the hydraulic fluid supply unit 52 to, for example, 40 ° C. or higher, raises the saturated vapor pressure of the dissolved gas, and performs vacuum degassing, thereby dissolving the dissolved gas in the hydraulic fluid, In particular, dissolved oxygen can be reduced, and a long-life heat pipe with stable performance can be produced.

  Although the third embodiment has been described based on the configuration of the first embodiment, the third embodiment can be similarly applied to the second embodiment.

Embodiment 4 FIG.
FIG. 6 is a configuration diagram of a gas-liquid sealing device according to Embodiment 4 of the present invention. FIG. 6 is based on the configuration of the third embodiment and includes a non-condensable gas temperature control unit 56 that controls the temperature of the non-condensable gas supply unit 24, and also includes a hydraulic fluid supply unit 52 and a non-condensable gas supply. A non-condensable gas pressure control unit 57 capable of automatically controlling the non-condensable gas supply pressure based on the temperature with the unit 24 is provided. The non-condensable gas pressure control unit 57 includes the temperature of the hydraulic fluid supply unit 52 controlled by the hydraulic fluid temperature control unit 55 and the temperature of the non-condensable gas supply unit 24 controlled by the non-condensable gas temperature control unit 56. From this correlation, the non-condensable gas supply pressure is determined, and the heat pipe is manufactured.

  Normally, the control of the installation temperature environment of the gas-liquid sealing device is rather strict (variation range ± 1 ° C or less), but according to the fourth embodiment, the non-condensable gas supply pressure is automatically controlled regardless of the temperature of the installation environment. Since the non-condensable gas pressure control unit 57 that can be used is provided, it can be manufactured even in an environment such as an office, and the capital investment is reduced.

  Although the fourth embodiment has been described based on the configuration of the third embodiment, it can be similarly applied to the first and second embodiments.

Embodiment 5 FIG.
FIG. 7 is a configuration diagram of the gas-liquid sealing device according to the fifth embodiment of the present invention. FIG. 7 is a configuration in which a heating unit is provided below the pipe 19 based on the configuration of the fourth embodiment. In FIG. 7, the heating means shows an oil bath composed of a heating container 59 and oil 58. A tape heater or a heating blower may be used instead of the oil bath.

  First, the working fluid is injected into the pipe 19 by the procedure described in the first embodiment. Thereafter, the valves 25, 35 and 33 are closed. Next, the hydraulic fluid poured into the pipe 19 is heated by the heating means, and the hydraulic fluid is boiled. Thereafter, the valve 33 is opened for a short time, and the gas inside the pipe 19 is discharged to the vacuum exhaust part 23 side. Thereafter, heating by the heating means is stopped. After returning the temperature of the pipe 19 to room temperature, a non-condensable gas is supplied to the pipe 19 as in the first embodiment. By removing the gas in the pipe 19 in this way, a heat pipe having a stable performance and a long life can be manufactured.

  Further, in a state where the lower part of the pipe 19 is heated by the heating means, the non-condensable gas supply pressure at the temperature of the heated state is determined based on a predetermined algorithm and controlled to the determined supply pressure. A non-condensable gas can also be supplied from the non-condensable gas supply unit 24 to the pipe 19. In this case, since it is not necessary to return the pipe 19 to room temperature, a heat pipe having a stable performance and a long life can be manufactured, and the production efficiency is also increased.

  Although the fifth embodiment has been described based on the configuration of the fourth embodiment, the fifth embodiment can be similarly applied to the first to third embodiments.

Embodiment 6 FIG.
FIG. 8 is a configuration diagram of the gas-liquid sealing device according to the sixth embodiment of the present invention. FIG. 8 is based on the configuration of the third embodiment, and includes a heat mass 61 attached near the lower portion where the working fluid of the pipe 19 is accumulated, a heater 62 attached to the heat mass 61, and heater control for controlling the output of the heater 62. The unit 60 is provided. The hydraulic fluid temperature below the pipe 19 is almost the same as that of the heat mass 61. The heat mass 61 is, for example, a block made of a highly heat conductive metal having a large heat capacity to some extent, and is a heating member that contacts the pipe 19. The output of the heater 62 is controlled according to the specifications of the heat pipe. Further, a thermocouple 63 is attached to the heat mass 61, and the pressure of the non-condensable gas supply unit 24 when supplying the non-condensable gas is controlled based on the temperature of the heat mass 61 measured by the thermocouple 63.

  The pressure is controlled by a temperature / pressure converter 64 to which the measured temperature is input. The temperature / pressure converter 64 calculates an adjustment pressure amount based on the amount of deviation between the input measured temperature and a preset heat pipe operation target temperature. This adjustment pressure amount is input to the non-condensable gas supply unit 24 through the control cable 65, and the pressure supplied from the non-condensable gas supply unit 24 is adjusted. The temperature / pressure converter 64 stores in advance data on the relationship between the temperature detected by the thermocouple 63 and the supply pressure in a memory or the like, and performs calculations using the relationship.

  The procedure of the manufacturing process will be described. After injecting a predetermined amount of hydraulic fluid into the pipe 19, the valves 35 and 33 are closed, and then the valve 25 is opened to supply the non-condensable gas of the preset non-condensable gas supply unit 24 to the pipe 19. . Next, a predetermined heater output is controlled by the heater control unit 60, and the temperature of the heat mass 61 is measured by the thermocouple 63. The temperature of the heat mass 61 is input to a temperature / pressure converter 64. The temperature / pressure converter 64 calculates an adjustment pressure amount based on the amount of deviation between the input temperature and the target operating temperature of the heat pipe. The supply gas pressure of the condensable gas supply unit 24 is controlled based on the adjusted pressure amount. By controlling the supply gas pressure in this way, the operating temperature of the heat pipe can be accurately adjusted to a desired specification.
