いてもその配管が制限されることとなった。Conventionally, the heat pipe used for the above purpose was made of metal or extremely thick plastic to maintain the performance, but it is particularly difficult to connect between objects in a fluid state because it is rigid. Therefore, the piping between the fixed objects is restricted.

慮すると柔軟なヒートパイプは殆ど使用することができ
なかった。On the other hand, when a heat pipe is simply manufactured by using a flexible material, the high temperature and high pressure fluid inside the pipe causes expansion of the pipe, resulting in a significant decrease in the moving speed of the fluid. If both are thickened, they become rigid and the heat exchange efficiency between the inside and outside of the beet pipe is reduced. As a result, considering the heat transport efficiency, a flexible heat pipe could hardly be used.

その目的とするものである。The present invention has been made in view of the above circumstances, and is a flexible heat pipe that makes it possible to prevent expansion due to inner pressure, and because it is not thick and is not rigid, connections, piping, etc. It is an object of the present invention to provide a flexible heat pipe which is convenient and has a wide range of installation, and has many advantages such as that the heat transport efficiency can be remarkably improved.

十分に有するものである。In the present invention, the heat pipe main body is made of a flexible material having a small friction coefficient and is formed in a relatively thin shape. In particular, a fluororesin, especially Teflon, is preferably used. Moreover, in addition to the metal tape 2 shown in FIG. 1, the carbon fiber mesh 4 shown in FIG.
Alternatively, the metal plating 5 shown in FIG. 3 (ii) is preferably used. All of these are tough, have a very low degree of stretching, and have sufficient resistance to block expansion of the pipe body even when a high-reduction, high-pressure heat medium flows at high speed inside the heat pipe body.

クが止むなく使用されていたものである。The flexible heat pipe according to the present invention thus formed is used as a pipe whose both ends are closed or a pipe which is connected in an annular shape to operate heat between a high temperature part and a low temperature part. That is, when the pipe is overheated in the high temperature portion, the heat medium is vaporized to become a high temperature and high pressure gas, which diffuses and flows at high speed.
That is, it is pumped. Conversely, it becomes a liquid when cooled to a low temperature. When high-pressure gasification is carried out, the pipe tends to expand, and when expansion occurs, the flow velocity of the heat transfer medium is remarkably reduced, and the heat transport material is reduced. For this reason, in the conventional heat pipe, metal or thick hard plastic is always used.

ートバルブを提供しうるものである。The present invention is based on the above structure, and is formed by forming a relatively thin heat pipe main body using a flexible material having a small friction coefficient, and applying a low stretch coating material to the outer periphery of the heat pipe main body. Therefore, the expansion due to the internal pressure can be sufficiently prevented, the flow velocity of the heat medium can be sufficiently increased, and the objects in the flow state can be easily connected. Thus, the heat transport efficiency is significantly improved and the installable range is remarkably expanded, and a very useful flexible heat valve can be provided.
