た。From the viewpoint of the performance of the heat pipe, it is very important to control the amount of the working fluid to be filled so as to be uniform. Since the open end of the container is sealed while boiling, it is extremely difficult to check the remaining amount of the working fluid and seal the container. As one method of equalizing control of the amount of hydraulic fluid enclosed, for example, the weight of a container before enclosing the hydraulic fluid and the weight of a completed heat pipe are measured, and only those having a difference between the two within a predetermined range are non-defective. And others are discarded as defective.
There was a problem that the yield was extremely low and the cost was high. Further, as another method, for example, a predetermined amount of a working fluid is injected into a container sealed at one end, and the working fluid is boiled, and the steam is discharged together with the non-condensable gas, and the discharge amount of the steam is measured. Then, it has been proposed to seal the open end of the container when the amount of discharged steam reaches a certain amount (Japanese Patent Laid-Open No. Hei 6-229693). But,
In this method, since only one heat pipe can be manufactured, there is a problem that productivity is low. In addition, in these methods of controlling the amount of hydraulic fluid enclosed, when the diameter of the container is small, bumping of the internal hydraulic fluid becomes intense, so that there is a problem that it becomes more difficult to control the amount of hydraulic fluid enclosed.

ことができた。EXAMPLE A lower region length L2 of a container 1 made of a copper alloy having an outer diameter of 3 mm, an inner diameter of 2.5 mm, a total length of 2,000 mm, and a lower end sealed therein
180 mm was set in the cooling means 2 and the upper region of the container 1 was set in the heating means 3 having a level difference L3 = 30 mm from the cooling means 2. In this state, the cooling means 2
The temperature was controlled so that the internal temperature of the heating means 3 was maintained at about 20 ° C., and the internal temperature of the heating means 3 was maintained at about 150 ° C.
At this time, the room temperature was about 25 ° C. First, the heating means 60
The inside of the tank 6 is heated up to 100 ° C. to evaporate the working fluid (water) a therein, and the valve 63 is opened to operate the vacuum pump 62 for a predetermined time to remove air and other gases in the tank 6 together with the above. Exhausted. Next, while continuously heating the inside of the tank 6, the first valve 7
After opening the vacuum pump 71 and evacuating the container 1 (10 -1 Torr), the valve 70 was closed and the second valve 80 was opened. The valve 80 was opened for about 60 seconds and closed, and the upper part of the container 1 was sealed with the caulking device 10. Respectively heat pipe of encapsulating a working fluid a to 30 pieces of container in the same manner, it was measured and the charging amount, the hydraulic fluid of the average 1cc at ± 10 mm 3 encapsulation removed hydraulic fluid a of each heat pipe I was able to confirm that it was. When the temperature characteristics of each heat pipe were confirmed, it was confirmed that the performance was good. In a similar manner, the second valve 80 for controlling the supply of the vapor of the hydraulic fluid a to the container 1 is provided.
Was changed in the range of 60 seconds or more, the working fluid a was sealed in each container 1, and the amount of working fluid sealed was measured. As shown in FIG. 3, a certain time (in this embodiment, It was confirmed that even if the working fluid vapor was continuously supplied to the container 1 for more than 40 seconds), the sealed amount hardly changed.

実にかつ効率よく実施することができる。According to the sealing method of the above embodiment, the amount of the working fluid sealed in the heat pipe can be controlled uniformly within an extremely small error range. Also, the working fluid can be more uniformly enclosed in a small-diameter container. According to the device of the first embodiment, the enclosing method of the above example can be reliably and efficiently performed.

It remains in the container 1 during sealing. Of course, when the upper end of the container 1 is sealed,
Although the steam remains therein, the volume of the steam is significantly larger than that of the working fluid in a condensed state, and even if they condense after sealing, the amount thereof is insignificant. Therefore, basically, it is considered that the amount of the working fluid condensed in the container 1 during the supply of the working fluid vapor substantially matches the amount of the working fluid sealed in the container 1.

The working fluid vapor condensed over the expected condensing area length L1 of the lower part of the container 1 ．203.7 mm including a part of the intermediate area within the level difference (30 mm) between the bottom part of the cooling means 2 and the upper part of the cooling means 2. It is presumed that. Therefore, when the cooling temperature of the cooling means 2 and the atmospheric temperature of the installation location of the apparatus are different from each other by a certain degree or more, the above-mentioned level difference L3 is reduced to the design limit of the apparatus, thereby cooling the lower part of the container 1. The amount of the working fluid enclosed can be controlled by the capacity within the region length (L2). Further, when the difference between the cooling temperature by the cooling means 2 and the heating temperature by the heating means 3 is small, when the steam of the working fluid is supplied into the container 1, the second valve 80 in the apparatus of the above embodiment is used. By lengthening the opening time, it is possible to reliably condense the amount of steam corresponding to the capacity within the length of the cooling area below the container 1 and control the amount of working fluid enclosed.

Each of the containers 1 can be connected to each other, and required portions of each container 1 can be set inside the same heating means 3 and the same cooling means 2. Therefore, when evacuation is performed from inside the container 1, one vacuum pump 7
