る。The heat transfer device consists of a pipe 1 and a thin nozzle 4 for liquid filling attached to the end portion 1a of which one end of the pipe 1 is drawn into a fully spherical shape.
It is composed of n and admonishes. The narrow nozzle 4 is welded to the end portion 1a using a brazing material 7. The end portion 1b on the opposite side of the pipe 10 is also drawn into a spherical shape, and the remaining hole in the center is sealed with a brazing material 6. After evacuating the air in the pipe 1 through the narrow nozzle 4 using a vacuum pump, an evaporative liquid 3 (for example, water, alcohol, fluorocarbon, etc.) is injected, and the end of the narrow nozzle 4 is caulked with gold, and the brazing material 5 is
Weld and seal. The heat transport action of this heat transfer device is performed as follows. When heat is applied to one end of the pipe 1, the liquid 3 inside the pipe 1 evaporates due to the heat, and steam is generated and flows through the entire vapor space in the center of the pipe 1 toward the other end due to the vapor pressure difference. move. The steam that reaches the other end is cooled, releases latent heat of condensation, and liquefies.

１の端末部１ａ。This liquid 3 is returned to its original state by gravity or by the capillary force of the groove 2 attached to the inner wall of the pipe 1, and repeats the same cycle as before. On the other hand, the condensation heat released at the other end is removed from the outer surface of the pipe 1 by convection of air and water. Since this heat transfer device makes full use of the evaporation-condensation action of the liquid 3, it is possible to transport a large amount of heat from one end of the pipe 1 to the other end with a small temperature difference. When manufacturing this heat transfer device, the important thing is to prevent the liquid from leaking out to the outside, or to prevent air from entering the inside from the outside.1. Evaporation of liquid 3 - condensation effect? The goal is to prevent it from decreasing. According to this specification, 6.7 tons of Al brazing material is used to make the hole in the part to be sealed smaller, and the pinhole that is likely to occur in the brazing material 6 and 7? It is important to reduce the amount. Terminal part 1a of pipe 1.

発生する場合もある。To process the spherical surface of 1b, as shown in Figure 2, add one pipe to the chuck of the lathe, rotate it, press the roller 8 against the end part, squeeze it, and process it into a spherical shape. At this time, as shown in Figure 3 Since the terminal portion 1b or 1a is squeezed, it is thicker than the main body of the Tsukibu 1. As the machining progresses, the speed of the end portion 1b (lB) increases and, moreover, that portion becomes work hardened, so that the remaining hole 1' is not easily reduced in size. In addition, if groove 2 is cut on the inner surface of pipe 1, 1
Stress concentration noise may occur at the 82' portion of the narrowed end portion 1b and cracks may occur.

Grooves 2 are provided except for i. Terminal part 1a of pipe 1
, 1b have a thinner inner surface by cutting them using a lathe or the like. If the thickness is made thin in this way, the end portions Ha and 1b will be squeezed and will not become thick at the time of death, as in the conventional example. This makes drawing process extremely easy, and the diameter of the round hole is also small.
The amount of brazing is reduced. Terminal part 1a of pipe 1.

こともなくなる。When processing the inner surface of 1b to make it thinner, it is possible to leave part of the groove 2 on the inner surface as shown in Fig. 6, but it is better to remove all the groove 2 without leaving it as shown in Fig. 7. is good in terms of stress concentration. In addition, if the pipe 1 is to have a smooth surface without leaving grooves 2 at both ends as shown in Fig. 7, a thin nozzle for injecting the evaporative liquid can be installed at one end of the pipe 1 using a brazing material. When attaching the tube to the tube and completely sealing the other end of the pipe 1 using brazing material, there is no possibility that the brazing material will flow inside and spread to the inner surface due to the capillary force of the groove, filling the groove. .
