的に極めて困難であった。It is well known that attaching fins to the surface of a heat transfer tube increases heat transfer efficiency, and it is known that placing a large number of needle-like fins on the surface of a heat transfer tube particularly improves the heat transfer effect. However, it was technically extremely difficult to plant a large number of needle-like fins on the heat transfer surface.

。The problems with heat transfer tubes in which many needle-shaped fins are planted around the outer circumference of the tube and their manufacturing are as follows. 〈0 12) If the flow rate of the cooling medium is increased to increase the heat transfer coefficient from a performance standpoint, the needle may fall down or bend. (3) If the tip of the needle is sharp, it may be unsafe to handle Missing.
本発明は上記（１１、＋２１ 、 ＋３１の問題点を解
消した伝熱管の製造法を提供しようとするものである。The present invention aims to provide a method for manufacturing a heat exchanger tube that eliminates the problems mentioned above (11, +21, +31).

々る。以下、本発明の一実施態様を第１図によって説明
する。Since a continuous wire is used, it is strong, and the tip of the fin has an appropriate curvature, so it is less dangerous. Furthermore, the manufacturing method is easy because the contact portions of the wire that are bent in a zigzag manner with the heat transfer tube are successively laser welded. Hereinafter, one embodiment of the present invention will be explained with reference to FIG.

溶接を行なうので製作が容易である。It is easy to manufacture because it is a regular fin made by bending a continuous wire in a zigzag pattern. Furthermore, the stiffness P can be set arbitrarily by simply winding the outer periphery of the heat exchanger tube in a spiral manner. Furthermore, since the contact portion between the fin and the heat transfer tube is laser welded with high heat density, manufacturing is easy.
（１） 連続量産型の製造方法のため製作コストが低
い。(1) Manufacturing costs are low due to continuous mass production type manufacturing method.
（２） ワイヤフィンは単線のまま途中で切られるこ
となく継がっており、見掛は上２本の線が突立っている
ため冷却媒体の流れた対し強度がある。(2) The wire fin is a single wire that is joined without being cut in the middle, and the two upper wires appear to stand out, providing strength against the flow of the cooling medium.
（３）先端は小さな曲率半径があり取扱上安全。(3) The tip has a small radius of curvature, making it safe to handle.
（４） ワイヤフィンのため冷却性能が高い。(4) High cooling performance due to wire fins.
