れ、複数の突起2a、2bは両偏平側面101゜102
に2列に並んで配されている。Conventionally, as a tube used in a heat exchanger, a tube having a plurality of protrusions 2a and 2b as shown in FIG. 4 is known (for example, Japanese Patent Application No. 59-500877). Both ends of the plate material are butt welded to form a flat shape having two flat side surfaces 101 and 102 facing each other. The butt welding part 3 is located at the connecting part of the two flat side surfaces 101 and 102, and the plurality of protrusions 2a and 2b are located at the connecting part of the two flat side surfaces 101 and 102.
They are arranged in two rows.
(発明が解決しようとする問題点〕
このようなチューブ1において、複数の突起2a、2b
は帯状板材を丸める以前にプレス成形により形成される
もので、このプレス時には多大な力が帯状板材に作用す
る。特に突き合せ溶接部3に近い位置にある突起2aを
成形する際には、そのプレス力が突き合せ端部まで影響
し、第5図に示す欅に突き合せ端部3a、3bが波打ち

ても良好に溶接するのが難しく、溶接不良が発生すると
いう問題がある。(Problem to be solved by the invention) In such a tube 1, a plurality of protrusions 2a, 2b
is formed by press forming before rolling the band-shaped plate material, and a large amount of force acts on the band-shaped plate material during this pressing. In particular, when forming the protrusion 2a located close to the butt weld 3, the pressing force affects the butt end, causing the butt ends 3a and 3b to become wavy as shown in Figure 5. As a result, even if the ends 3a and 3b are welded, it is difficult to weld them well, resulting in a problem of welding defects.
゛そこで本発明では、偏平チューブの一方の偏平側面の
略中央部に突き合せ溶接部を位置させ、他方の偏平側面
のみに複数の突起を形成した。Therefore, in the present invention, a butt weld is located approximately at the center of one flat side surface of the flat tube, and a plurality of protrusions are formed only on the other flat side surface.
従って、突起と溶接部とが異なる偏平側面に位置してい
るので、突起を形成した際の応力の溶接部への影響が殆
ど無く、帯状板材の突き合せ端部に歪が発生することな
く良好に溶接を行うことができる。Therefore, since the protrusion and the welded part are located on different flat sides, the stress generated when the protrusion is formed has almost no effect on the welded part, and there is no distortion at the butt end of the strip material. can be welded to.

Figures (a) to (6) are schematic diagrams showing the manufacturing process of the tube 1. First, the protrusions 2a and 2b are press-formed on the strip-shaped plate material 100 using a pair of punches 201 and dies 200 (FIG. 6(a)). Next, the butt ends 3a and 3b of the strip-shaped plate material 100 are formed into an R shape. Press with a pair of punches 203 and a die 204 so that the shape is formed (FIG. 6(b)).Next, press the punch 206 at the intermediate position between the protrusions 2a and 2b,
The strip-shaped plate material 100 is formed into a 0-shape along the 7-shaped die 205 (FIG. 6(C)), and this 7-shaped strip material 100 is formed into a circular tube. figure(
