例えば押出法で製造された中空状のパイプの内壁の全面
に金網等のウイックをパイプの端部から挿入し装着した
構造のものが知られている。(Prior art) (Problems to be solved by the invention) Conventional heat pipes are used as heat pipes.
For example, there is known a structure in which a wick such as a wire mesh is inserted from the end of a pipe and attached to the entire inner wall of a hollow pipe manufactured by an extrusion method.
しかしながらかかるヒートパイプは、内壁面に前記の
ウイック材料を正確に装着することは困難であり、かつ
装着の確認も容易ではない。However, in such a heat pipe, it is difficult to accurately mount the wick material on the inner wall surface, and it is not easy to confirm the mounting.

とが課題となっていた。For this reason, the present inventor has solved this problem by using a technique in which a metal tape is formed into a pipe shape by round forming with a vertically-attached roll, and by attaching the wick layer to the inner surface of the metal tape so that the wick layer can be tightly attached without any gap. Suggested.
However, in this structure, it has been a problem that the holding force of the working fluid depends solely on the thickness and density of the wick, so that it is still improved.

きる。(Operation) According to the present invention, the wick layer can be easily manufactured by using a metal tape formed on one side of the pipe before the pipe is formed, and the wick layer can be formed into a pipe in the state of a raw pipe. Since the pipes have grooves of an appropriate length at regular intervals in the axial direction of the pipe, the working fluid traveling along the wall surface inside the heat pipe is likely to temporarily stay in and around the grooves,
Since the entire pipe is not required to be processed, there is no danger of peeling of the wick layer. Also, since the pipe is formed with an irregular length, that is, a groove, on the surface of the pipe, reinforcement against crushing of the pipe as a result. The effect is also enhanced, and the hydraulic fluid will stay in this groove as appropriate, especially for long heat pipes used in vertical use, the effect is remarkable, long heat pipes that pump up geothermal heat An extraordinary effect can be exerted so that the working fluid is distributed over a wide range.
