Abstract

PURPOSE:To form a projecting arrow-formed tube turning the center part in the width direction of the flat part of a tube to the external direction by arranging plural projections turning to the internal part of the tube on the flat sides of the tube as the flat part with a required width is left in the central part in the width direction of the tube. CONSTITUTION:A belt-shaped sheet metal 408 is taken out of a metal material 407 obtained from a flat sheet metal wound in a coil form and passed between a pair of projection-forming rollers 409 to prepare dimples on the sheet material 408. After that, while the sheet material passes between a group of the 1st forming rollers 410 a core metal 130 is inserted into the internal part to bend the sheet material 408. Then, after the end part 123 is rolled and laminated by compression rollers 411 for a rolled and laminated part it is rolled and laminated finally by a group of a 2nd forming rollers 412 as the core metal 130 is inserted. Thereafter, the core metal 130 is removed out of the tube 2 and the tube goes into a solder tank 415 to solder its external circumference. The tube is formed in the cooling tank 416 and finished by a group of finish rollers 417 in the form of a desired tube.

In order to make the flat side of the tube curve outward (hereinafter referred to as a convex shape), when forming the tube 601, a general method is to create a cross-section inside the tube 601. The most common method is to insert a barrel-shaped core and form the tube along this core.

A core metal 130 arranged inside such a flat tube 102
As shown in FIG. 1(b), it has a cross-sectional shape in which the wall thickness is thick at the center and the wall thickness is thin at both ends. That is, the thickness of the core metal in the portion of the tube 102 facing the dimples 120a and 120b is reduced by the amount of protrusion of the dimples.
Further, flat portions 121 and 12 where no dimples are formed.
The surface facing the tube 102 is made thicker than other portions so that the cross section perpendicular to the axis of the tube 102 has a medium convex shape. Since the band-like plate material of the flat tube 102 is bent along the central thick part of the core bar 130, as a result, the flat tube 102 has a convex shape with the center part in the width direction arched outward. It is. Note that at this time, the dimples 120a and 120b are arranged on both sides of the tube 102, leaving flat portions 121 and 122 at the center of the tube 102, so the dimple 120a.

In addition, in the embodiment shown in FIG. 1, the flat tube 102
Although the dimples 120a formed on one flat side surface and the dimples 120b formed on the other flat side surface were exactly the same in shape, for example, as shown in FIG. The dimple 120b formed on the other flat side surface may be formed to have a longer length in the width direction.

The length l of the portion is set to approximately 2 mm or more. Further, in the embodiment shown in FIG. 2, since the flat portion 121 on one flat side surface and the flat portion 122 on the other flat side surface have different lengths in the width direction, the thick portion of the core bar 130 is adjusted to match the length. The shape is also molded.

The tube 102 is formed using an apparatus as shown in the schematic diagram of FIG. First, a strip-shaped plate material 408 is taken out from a metal-like material 407 made by winding a flat metal into a coil shape, and passed through a pair of protrusion-forming rollers 409.
Dimples 120a and 120b are formed on the strip-shaped plate material 408, as shown in FIG. 5(a). Then, while passing through the first forming roller group 410, the core bar 130 is inserted therein, and the strip-like plate material 408 is bent to the state shown in FIG. 5(B).

After that, the final seamed tube 102 is attached to the core metal 1.
30 is removed, enters the solder tank 415,
Solder is coated on the outer periphery of the tube, and then it is formed in a cooling layer 416, and then finished by a group of finishing rollers 417 into a desired tube shape. Then, the tube 102 is cut into a predetermined size at a cutting section 419, and the forming of the tube 102 is completed. Note that 418 is a pulse generator that controls the cutting operation of the cutting section 419.

When stacking the corrugated fins between the tubes 102, the tube 102 has a convex cross section, so when the corrugated fins 103 are pressed against the flat side of the tube, the convex shape will be the same. The tube is elastically deformed inward by its elastic force, and as a result, when the fins and tube are assembled, the flat side surface of the tube becomes flat instead of arched. Therefore, the connection between the tube and the corrugated fin can be ensured sufficiently. If the cross-sectional shape of the tube 102 were not a convex shape but a concave shape concave toward the inside, a space would exist between the tube and the corrugated fin when they were joined. , a problem arises in that the bonding between the two is not sufficient.

[Scope of Claims] A tubular tube having a flat cross section perpendicular to the axis, and a wavy fin joined to the flat side surface of the tube, the tube having its ends joined by bending a band-shaped plate material. The tube is formed into a flat tube shape, and a plurality of protrusions protruding toward the inside of the tube are formed on the flat side surface of the tube, and these protrusions have a flat shape of a predetermined width in the widthwise center of the tube. The heat exchanger is arranged such that the tube is arranged in a cross section perpendicular to its axis, and the flat side surface of the tube is formed into an arch shape from the inside of the tube to the outside of the tube.
