この発明はヒートパイプを製造する際に作動液

力排気しておく必要がある。 As is well known, a heat pipe is a sealed tube that has been evacuated to exhaust non-condensable gases, and a condensable working fluid such as water or ammonia is sealed in it, and by applying heat to one end, the working fluid evaporates. The condensed working fluid is circulated through the wick, and the working fluid repeats evaporation and condensation in this way, creating a circulating flow. This allows continuous heat transport. In such heat pipes, it is necessary to fill a specified amount of working fluid in order to prevent the heat transport capacity from decreasing or being interrupted due to things such as the pipe drying out.
Furthermore, in order to prevent evaporation of the working fluid and the flow of the gas-phase working fluid, it is necessary to exhaust as much non-condensable gas as possible, such as air.

た。 By the way, in manufacturing the heat pipe as described above, a method shown in FIG. 1, for example, is conventionally known as a method of injecting a specified amount of working fluid into the heat pipe material tube. That is, the evacuation device 1 and the metering tube 2 with scales are connected to the heat pipe base tube 3 via valves V 1 , V 2 , V 3 , and when the valves V 1 and V 3 are opened, Start the vacuum evacuation device 1 and remove the heat pipe material tube 3.
After exhausting non-condensable gas such as air inside the tube, close the valve V 1 on the evacuation device 1 side, then open the valve V 2 on the measuring tube 2 side, and while watching the scale, check the inside of the measuring tube 2. A specified amount of the working fluid 4 is injected into the heat pipe tube 3, and then the valve V 2 ,
This is how to close V3 . However, in the conventional method described above, the valve is adjusted while checking the scale attached to the metering tube 2.
Since V 2 must be adjusted, the work is troublesome and lacks speed, and each valve V 1 ,
Since air remains in the pipe surrounded by V 2 and V 3 , the air enters the heat pipe base tube 3 when the working fluid 4 is injected, and as a result, the performance of the resulting heat pipe deteriorates. I had a problem with it going down.

業に長時間を要するなどの問題があつた。 Conventionally, as a method to prevent the incorporation of non-condensable gases as much as possible, a predetermined amount of working fluid is injected into the heat pipe base tube, and the working fluid is cooled and solidified.
A method is known in which the fluid is then evacuated, but this method causes problems such as the working fluid solidifying while still containing air, requiring large-scale solidifying equipment, and requiring a long time to perform the work. It was hot.

Another object of the present invention is to provide a method for quantitatively injecting a working fluid into a heat pipe, which can improve productivity, and an apparatus for carrying out the method.

By vacuum degassing the inside of the sealed container with the container open,
Exhaust non-condensable gas from multiple heat pipe tubes at the same time, raise the hydraulic fluid tank with the valve closed until the liquid level is above the upper end of the metering pipe, and then lower the hydraulic fluid tank. By lowering the liquid level, each metering pipe is filled with working fluid, which measures the amount of working fluid to be injected.Then, by opening the valve, the working fluid flows from the metering pipe into each heat pipe base tube. The present invention is characterized in that a prescribed amount of working fluid is injected into each heat pipe base tube.

が入り込むおそれはない。 Next, the operation of the apparatus configured as described above, that is, the injection method of the present invention will be explained. First, connect the heat pipe base tube 14 to the lower end of the metering pipe 12, lower the working fluid tank 19, and close the valve 18. In this state, the valve 14 provided at the lower end of each metering pipe 12 and a valve 1 provided between the closed container 10 and the vacuum exhaust device 15
After opening 6, the evacuation device 15 is activated to exhaust non-condensable gas such as air inside the closed container 10 and the heat pipe tube 14. After the exhaust is completed,
The valves 13 and 16 are closed, and then the working liquid tank 19 is raised to the same height as the closed container 10 or to a slightly higher position, and the valve 18 provided in the communication pipe 17 is opened. Then, as shown in FIG. 3, the hydraulic fluid 22 flows from the hydraulic fluid tank 19 into the closed container 10 due to the head difference, and the fluid level becomes higher than the metering pipe 12.
The hydraulic fluid 22 enters the metering pipe 12 until it is full.
Thereafter, when the hydraulic fluid tank 19 is lowered to the original position shown in FIG.
2 is full and the liquid level is 1.
By opening the valve 13 provided at the lower end of the metering pipe 12, the working fluid 22 in the metering pipe 12 is injected into the heat pipe base tube 14. Therefore, by adjusting the internal volume of the metering pipe 12 to match the heat pipe base tube 14 connected to it, in other words, the heat pipe base tube 14 can be adjusted to match the amount of working fluid to be injected into the heat pipe base tube 14. By connecting the metering pipe 12 with the matching internal volume, the hydraulic fluid 22
without measuring the specified amount of hydraulic fluid 2.
2 can be injected into the metering pipe 14.
Moreover, if the working fluid 22 is injected as described above, since the metering pipe 12 and the heat pipe base tube 14 are directly connected, there is no risk of air entering the heat pipe base tube 14.

Further, in order to remove the heat pipe material tube 14 after the injection is completed, the upper end portion thereof is crimped and sealed, and the heat pipe material tube 14 is cut just above the crimped portion.

い。 In the embodiment described above, the internal volume of each metering pipe 12 is approximately the same, but the present invention is not limited to the above embodiment, and the inner diameter or length of a plurality of metering pipes may be made different. The internal volume of each metering pipe may be made to be different, and in this way, the working fluid can be simultaneously injected into many types of heat pipe base tubes having different capacities. Furthermore, in the above embodiment, the liquid level in the sealed container 10 is changed by moving the hydraulic fluid tank 19 up and down. An appropriate pump is provided between the containers, and the pump closes the airtight container 1.
It may be configured to change the liquid level within 0.

ることが可能になる。 As is clear from the above explanation, according to the method for quantitatively injecting hydraulic fluid of the present invention, a metering pipe whose internal volume is set to a predetermined amount in advance is filled with hydraulic fluid until it is full.
The heat pipe base tube is connected to the lower end of the metering pipe, and the working fluid in the metering pipe is injected downward into the heat pipe base tube, so just by filling the metering pipe with the working fluid, you can A specified amount of working fluid can be injected into the heat pipe material tube without measuring, and therefore the injection work can be performed easily and quickly. Further, according to the hydraulic fluid injection device of the present invention, the metering pipe whose internal volume is set to a predetermined amount in advance is arranged so as to penetrate through the bottom of the closed container so that the base tube for the heat pipe can be connected to the lower end of the metering pipe. Then, non-condensable gases such as air are evacuated from the inside of the sealed container and the heat pipe tube by a vacuum evacuation device connected to the sealed container, and the working fluid supplied from the hydraulic fluid tank is removed from the sealed container. Since the liquid level is moved up and down, it is possible to easily and quickly inject the working fluid into the heat pipe base tube in the same way as the method described above. Since the air is directly connected and injected, there is no risk of air entering the heat pipe base tube, and therefore a heat pipe with good performance can be obtained. In addition, if multiple metering pipes with different internal volumes are installed as metering pipes, the working fluid can be injected into multiple heat pipe base tubes with different capacities at the same time, making it possible to mass-produce a wide variety of heat pipes. becomes possible.
