Gem. Fig. 1 (Seitenansicht) und Fig. 2 (Draufsicht) werden an ein Blech 1, welches mit längs des Bleches 1 verlaufenden Sicken 5 versehen wurde und in dem Durchströmöffnungen D1 eingestanzt sind, die Heizrohre 4 fluchtend mit den Durchströmöffnungen D1 angeschweißt. Das offene Ende des Heizrohres bildet dessen Durchströmöffnung D2. Der Durchmesser d1 der Durchströmöffnung D1 ist in etwa identisch mit dem Innendurchmesser d2 des Heizrohres 4 und somit mit der Durchströmöffnung D2. Die Sickentiefe beträgt ca. 30% der Blechdicke s. Der Abstand 1 der Sicken wird entsprechend der Kantenlänge des zu erzeugenden Profiles des Sammlers gewählt.Gem. Fig. 1 (side view) and Fig. 2 (plan view) are the heating tubes 4 are welded to a sheet metal 1, which has been provided with longitudinally of the sheet 1 extending beads 5 and are stamped into the through-flow D1 in alignment with the through-flow D1. The open end of the heating tube forms its flow opening D2. The diameter d1 of the throughflow opening D1 is approximately identical to the inside diameter d2 of the heating tube 4 and thus with the throughflow opening D2. The bead depth is approx. 30% of the sheet thickness s. The distance 1 of the beads is chosen according to the edge length of the profile of the collector to be generated.
In Fig. 3 ist dargestellt, wie das Blech 1 beidseitig nach oben gebogen wird. Die Blechdickenreduzierung im Bereich der Sicken wirkt dabei als Sollbiegestelle und verringert die erforderliche Biegekraft.In Fig. 3 it is shown how the sheet 1 is bent upwards on both sides. The sheet thickness reduction in the area of the beads acts as a predetermined bending point and reduces the required bending force.
In Fig. 4 ist der fertig gebogene Sammler 4 mit rechteckigem Querschnitt dargestellt. Die Blechenden 1a liegen im Stumpfstoß in der Mitte der Oberseite des Sammlers aneinander an und wurden verschweißt (Schweißnaht 6). Eine ähnliche Variante zeigen Fig. 5 und 6, jedoch wurden die Enden des Bleches 1, die die Oberseite des Sammlers 2 bilden, in einem Radius eingerollt, so daß insgesamt gem. Fig. 6 ein D-förmiges Profil des Sammlers gebildet wird. Auch hier wurden die Sicken 5 so angeordnet, daß die Schweißnaht 6 oben in der Mitte des Sammlers 2 liegt.In FIG. 4, the finished sheet-collector 4 is shown with a rectangular cross-section. The sheet ends 1 a lie in the butt joint in the middle of the top of the collector and were welded (weld 6 ). A similar variant, FIGS. 5 and 6, but the ends of the sheet 1 forming the top of the collector 2 were rolled in a radius, so that a total gem. Fig. 6 a D-shaped profile of the collector is formed. Here, too, the beads 5 were arranged so that the weld seam 6 lies at the top in the middle of the collector 2 .
In Fig. 6a wird ein mit Fig. 6 baugleicher Sammler 2 dargestellt, jedoch liegt die Schweißnaht 6 an einer Kante und das Heizrohr 4 ist um 90° versetzt angeordnet. FIG. 6a shows a collector 2 which is identical in construction to FIG. 6, but the weld seam 6 lies on one edge and the heating tube 4 is arranged offset by 90 °.
In Fig. 7 wurde das Blech 1 lediglich mit zwei Sicken 5 versehen. In dem mittleren Blechbereich wurden wiederum die Durchströmöffnungen D1 eingebracht und dazu fluchtend die Heizrohre 4 angeschweißt. Durch Biegen der beiden äußeren Blechschenkel nach oben wird das Blech 1 im Bereich der Sollbiegestellen in Form der Sicken 5 gebogen. Es entsteht gem. Fig. 8 ein dreieckiger Sammler 2 mit obenliegender Schweißnaht 6.In Fig. 7, the sheet 1 was only provided with two beads 5 . The throughflow openings D1 were again introduced in the central sheet metal area and the heating tubes 4 were welded in alignment for this purpose. By bending the two outer sheet metal legs upward, the sheet metal 1 is bent in the form of the beads 5 in the area of the predetermined bending points. According to Fig. 8 is a triangular collector 2 with overhead weld. 6
Werden die Heizrohre 4 nicht mittig am Blech 1 verschweißt, sondern in einem anderen Bereich zwischen den Sicken 5 oder an einem an der Außenseite liegenden Blechbereich, so verschiebt sich entsprechend die Position der Schweißnaht 6. In Fig. 9 wurden die Heizrohre 4 an dem mit drei Sicken 5 versehenen Blech 1 an dessen rechter Außenseite angeschweißt. Die links liegenden Bereiche des Bleches 1 werden zueinander rechtwinklig gebogen, so daß das in Fig. 10 dargestellte rechteckige Profil entsteht, bei welchem die Schweißnaht 6 in einer unteren Ecke des Sammlers 2 liegt.If the heating pipes 4 are not welded in the center of the sheet metal 1 , but in another area between the beads 5 or on a sheet metal area located on the outside, the position of the weld seam 6 shifts accordingly. In Fig. 9, the heating tubes 4 were welded to the sheet 1 provided with three beads 5 on the right outside thereof. The areas of the sheet metal 1 on the left are bent at right angles to one another, so that the rectangular profile shown in FIG. 10 is formed, in which the weld 6 lies in a lower corner of the collector 2 .
Neben den vorgenannt beschriebenen Varianten ist es auch möglich, Sammler mit anderen Profilformen herzustellen. Zur abschließenden Fertigstellung werden die Enden des Sammlers in bekannter Weise verschlossen.In addition to the variants described above, it is also possible to produce collectors with other profile shapes. For the final completion, the ends of the Collector closed in a known manner.
Gemäß Fig. 11 ist es auch möglich zwei zueinander parallele Reihen von Heizrohren 4 mit dem Sammler 2 zu verbinden. Fig. 12 zeigt einen erfindungsgemäß hergestellten Heizkörper mit rechteckigen, senkrecht angeordneten Sammlern 2 und dazwischen sprossenartig querliegenden Heizrohren 4.Referring to FIG. 11, it is also possible to connect two parallel rows of heating pipes 4 with the header 2. FIG. 12 shows a radiator produced according to the invention with rectangular, vertically arranged collectors 2 and heating pipes 4 lying transversely between them.
Gem. Fig. 13 reichen die Heizrohre 4 über die Sammler 2 hinaus. Gem. Fig. 13 rich, the heating pipes 4 beyond the header 2.
Eine Variante der Verbindung zwischen Sammler und Heizrohr und vor und nach dem Biegen des Bleches ist in Fig. 14 und 15 dargestellt. Die Heizrohre 4 weisen z. B. einen ovalen Querschnitt auf und sind an den Enden verschlossen. Sie liegen mit einer Seitenwandung, in welcher sich die Durchströmöffnung D2 befindet, an dem Blech 1 an.A variant of the connection between the collector and the heating tube and before and after bending the sheet is shown in FIGS. 14 and 15. The heating tubes 4 have z. B. an oval cross-section and are closed at the ends. They rest on the sheet metal 1 with a side wall in which the throughflow opening D2 is located.
Mit der erfindungsgemäßen Lösung wird die Herstellung eines gattungsgemäßen Heizkörpers wesentlich vereinfacht und es wird erstmalig möglich, aus Richtung der späteren Innenseite des Sammlers 2 Blech 1 und Heizrohr 4 zu verschweißen, wodurch die Qualität wesentlich verbessert wird. Die Verwendung eines Bleches 1, welches zu dem Sammler gebogen wird, ermöglicht eine große Formenvielfalt bei geringen Kosten. Insgesamt wird eine neuartige und elegante Herstellungsweise für Röhrenheizkörper geschaffen. Durch die möglichen gratfreien Schweißnähte kann der Nacharbeitungsaufwand auf ein Minimum reduziert werden.With the solution according to the invention, the manufacture of a generic radiator is considerably simplified and for the first time it is possible to weld sheet 1 and heating tube 4 from the direction of the later inside of the collector 2 , as a result of which the quality is significantly improved. The use of a sheet 1 , which is bent to the collector, enables a wide variety of shapes at low cost. Overall, a new and elegant production method for tubular radiators is created. Thanks to the possible burr-free weld seams, reworking can be reduced to a minimum.
