生ずるような隙間ができ易いという欠点を有している。Solar heat absorption panels or plate type heat exchangers, which are attracting attention as an energy saving measure, form a flow path between two metal slopes, and a heat exchange medium is distributed through this flow. The method of manufacturing the exchanger is to overlap two unformed metal plates and weld the periphery, then resistance weld the parts other than the flow path forming part by spot welding or seam welding, and then attach them to the required jig. There is a method of bulging forming the unwelded passage forming part by restraining the part and injecting fluid. However, spot welding has the advantage that it can be formed at low bulge pressure and is unlikely to create gaps that could become a starting point for corrosion near the welded part, but it has the disadvantages that it is difficult to provide directionality to the flow path and it is not possible to increase the strength of the panel. Also, seam welding has the advantage of adding strength to the panel and providing directionality to the formed flow path, but the disadvantage is that it requires high bulge pressure and tends to create gaps that can cause crevice corrosion. have.

。The present invention suppresses the drawbacks of both as mentioned above and combines the advantages of both to achieve excellent performance, corrosion resistance, and strength.
We succeeded in creating a panel that is easy to mold.
When forming the flow passages of solar heat absorbing panels or plate heat exchangers by bulging after resistance welding, it is possible to easily manufacture the panels by effectively combining spot welding and seam welding and performing anti-welding tests. At the same time, the purpose is to improve crevice corrosion resistance, and when manufacturing solar heat absorption panels or plate-type heat exchangers by bulge forming, spot welding or roll spot welding is used as resistance welding to form flow channels. Adopting both seam welding,
It is characterized by providing one or more rows of spot welding or roll spot welding in the seam welding.

により上記の目的を達成せしめたものである。That is, in carrying out the present invention, seam welding has the disadvantage that the welded portion is long and the total heat input is large, so that thermal distortion is likely to occur in the panel, so spot welding or roll spot welding is performed first, and then Preferably, the seam welding is carried out after the spot welding has been carried out, and resistance welding achieves the above object by providing one or more rows of spot welds within the seam welding.
次に本発明の実施例を図面に基いて説明する。Next, embodiments of the present invention will be described based on the drawings.

成形するものである。In the accompanying drawings, FIGS. 1A and 1B are explanatory top views of panels manufactured by the conventional method, and FIGS. 2A and 2B are explanatory top views of panels manufactured by the method of the present invention. To manufacture a solar heat absorption panel, as shown in Fig. 1, two metal plates 1 having openings 2 are superimposed, the periphery is seam welded 3, and the parts other than the flow path forming part are spot welded or After roll spot welding 4 (see Fig. 1a) or seam welding 5 (see Fig. 1b), fluid is injected through the opening 2 to form a bulge flow path. As shown in Fig. 2, when resistance welding the parts other than the above-mentioned flow foundation forming part, either spot welding or roll spot welding 6 and seam welding 7 are performed alternately, and each weld is done one row at a time. (see Fig. 2a) or, for example, two rows of spot welds 6 are formed between the seam welds 7 (see Fig. 2b), and then fluid is pressurized in the same manner as before to form a flow path. It is something.
本発明はこのようにスポット溶接とシーム溶接とを併用
することにより、スポット溶接とシーム溶接との長所が
生かされ低いバルジ成形圧で隙間のない流路が形成され

破壊されるため有効伝熱面積が少なくなり、熱効率が低
下するのが両者を併用することによりこれを軽減するこ
とができるなどの利点を有するものである。By using spot welding and seam welding together in this way, the present invention takes advantage of the advantages of spot welding and seam welding, and forms a flow path with no gaps at low bulge forming pressure. Not only does it have excellent effects such as increasing the strength of the panel and giving direction to the rocky shore, but it also makes it easier to select the panel when welding metal plates with a selective absorption film and only seam welding. Since the absorption film is destroyed, the effective heat transfer area decreases and the thermal efficiency decreases. However, by using both together, this can be reduced.
