が悪い欠点があつた。(b) Prior Art A method of manufacturing a heat exchanger using a conventional spine fin inch tube will be explained. For example, in the case of bending into a U-shape, a spine fin inch tube 2 with a layer of spine fins 1 on the outer periphery as shown in FIG. The heat exchanger 5 shown in FIG. 3 is obtained by clamping and pressing with an external jig 4 and bending it into a U-shape, but since the spine finches 2 are pressed from the outside,
There is a drawback that the spine fin 1a at the pressed location is completely deformed, and the U-shaped bending has limitations in terms of installation space in order to secure a desired heat exchange area. For this purpose, there is a method of spirally winding the spine finches as shown in, for example, Japanese Patent Publication No. 715/1982 or Japanese Patent Publication No. 47464/1989.
However, in the former method of winding around a rotating drum, the spine fins and pipes must be spirally shaped with a relatively large inner diameter in order to reduce deformation, and the installation space for the heat exchanger becomes large. It cannot be used in refrigerators, etc. Further, when forming from the outside using a group of rollers as in the latter case, there was a drawback that heat exchange efficiency was poor because fins could not be formed on the spiral outside.

It has an outer diameter d 2 smaller than the inner diameter d 1 by an appropriate clearance, and extends substantially linearly in the longitudinal direction, and the extended tip 9a has a curved shape (arrow a) corresponding to the turning diameter of the spiral. ) and pitch (P)
A corresponding twist (indicated by arrow b) is formed. The spine fin inch tube 6 is inserted into this jig 9 from the straight part of the jig. After the tube 6 is inserted, a fixing jig 10 is fixed to the jig 9 and the exposed portion 9b, and the jig 9 is fixed with this fixing jig 10. After fixing the jig 9, the feeder 11 is moved along the jig 9 by an arrow 9 using a feeder (not shown).
Slide it in direction c. Then, the spine fin inch tube 6 is pushed out in front of the jig 9 via the feeder 11. When the spine inch tube 6 passes the tip 9a of the jig 9, it is bent in the turning direction according to the curved form (indicated by arrow a),
At the same time, it is bent in the pitch (P) direction according to the twist (indicated by arrow b), resulting in the desired spiral shape.
