Abstract
The heating elements such as radiators are made from a number of flat tubes and their ends are covered with angular closing profiles. The flat stacked tubes are welded at their end edges. Hence connecting vertical openings are formed and the angle profile is welded along the outer edge to the flat tubes. An enclosed heating element is formed and the end profile produces a continuous vertical channel which connects the individual flat tubes. This heating element can be readily produced by welding.
Description
Die vorliegende Erfindung betrifft einen Heizkörper mit an ihren Schmalseiten zusammenstossenden Flachrohren.
Es ist eine aus einer Mehrzahl von satt übereinanderliegenden miteinander kommunizierenden und stirnseitig abgeschlossenen Rohren gebildeter Heizkörper bekannt, bei welchem benachbarte Rohre durch in ihren Schmalseiten gebildet, sich deckende Öffnungen unmittelbar miteinander kommunizieren.
Die Herstellung dieser Heizkörper verlangt das Anbringen von Öffnungen in den einzelnen Flachrohren und ein Verschweissen der Flachrohre im Bereiche dieser Öffnungen. Das Herstellungs verfahren von Heizkörpern auf diese Art ist kostspielig und in der Massenfabrikation zu teuer.
Es ist ferner ein Heizkörper bekannt geworden, der aus mit ihren Schmalseiten mindestens annähernd zusammenstossenden Flachrohren hergestellt ist, wobei bei mindestens einer Schmalseite jedes Rohres ein Schlitz gebildet wird und die Schlitzkanten benachbarter Rohre an der Rohrinnenseite miteinander verschweisst sind. Diese Konstruktion ist ähnlich der vorbeschriebenen mit dem Unterschied, dass die Öffnungen an den Flachrohrenden als Schlitze ausgebildet sind, was die Herstellung vereinfacht. Aber auch bei dieser Konstruktion muss längs des Schlitzumfanges das Zusammenschweissen der Flachrohre erfolgen. Auch dies ist eine arbeitsintensive Herstellung von Heizkörpern. Die vorliegende Erfindung bezweckt die Schaffung eines diesbezüglichen einfacheren Heizkörpers.
Der erfindungsgemässe Heizkörper ist dadurch gekennzeichnet, dass mindestens eine Stirnseite des Heizkörpers mit einem Abschlussdeckel verschweisst ist, der als die Flachrohre stirnseitig verbindender, in seinem Innern frei durchgängiger Teil ausgebildet ist, wobei der Deckel die Stirnseite und einen Teil der einen Flachseite der Flachrohre bildet.
Der Erfindungsgegenstand wird anschliessend beispielsweise anhand zweier Figuren erläutert. Diese stellen rein schematisch und perspektivisch einen Teil eines aus Flachrohren zusammengesetzten Heizkörpers im Ausschnitt mit winkelförmigem Abschlussprofil dar.
Die Flachrohre 1 sind an ihrem Ende mit einem Schrägschnitt 3 versehen, wobei die Schnittebene zur Flachrohrlängsachse 18 in einem von 90o abweichenden Winkel steht. Die übereinanderliegenden Flachrohre 1 sind an ihren Schmalseiten 9 und 10 verschweisst. Auf diese Weise entstehen übereinanderliegende Öffnungen 5 der Flachrohre 1 mit einer Gesamtaussenrandung 7. Die Längsseiten der einzelnen Öffnungen 5 sind mit 12 bzw. 13 bezeichnet. Zwecks Bildung eines durchgehenden Kanals 22 an den schräg geschnittenen Enden der Flachrohre 1 ist eine auf ihren Stirnseiten geschlossene Winkelschiene 15 längs der Aussenrandung 7 mit den Flachrohren 1 verschweisst. Es entsteht dadurch ein geschlossener Heizkörper, dessen Ende, gebildet durch die Winkelschiene 15, den durchgehenden Kanal 22 festlegt, der die Innenräume der Flachrohre miteinander verbindet.
Im dargestellten Beispiel der Fig. 1 ist der aufgeschweisste Abschlussdeckel als Winkelschiene 15 ausgebildet. Es können aber auch andere Formen gewählt werden, beispielsweise eine U-Schiene 19 vorzugsweise mit ungleicher Schenkellänge, welche bewirkt, dass die eine Hauptseite 20 der Flachrohre am Ende erkerähnlich vorsteht, wie dies schematisch in Fig. 2 ersichtlich ist. Dabei bildet die eine Seite 21 des Abschlussdekkels 19 die Stirnwand des Heizkörpers, während die andere, eben (Fig. 1) oder abgesetzt (Fig. 2), einen Teil der einen Flachseite 20 des Heizkörpers bestimmt.
Die Herstellung eines derartigen Heizkörpers ist äusserst einfach und zweckmässig.

The present invention relates to a radiator with flat tubes butting together on their narrow sides.
A radiator formed from a plurality of tubes that communicate with one another and are closed at the end is known, in which adjacent tubes communicate directly with one another through openings that are formed in their narrow sides and that overlap.
The manufacture of these radiators requires the making of openings in the individual flat tubes and the welding of the flat tubes in the area of these openings. The manufacturing process of radiators in this way is costly and too expensive to mass-produce.
A radiator is also known which is made of flat tubes which at least approximately meet with their narrow sides, a slot being formed on at least one narrow side of each tube and the slot edges of adjacent tubes being welded together on the inside of the tube. This construction is similar to that described above, with the difference that the openings at the flat tube ends are designed as slots, which simplifies production. But even with this construction, the flat tubes must be welded together along the circumference of the slot. Again, this is a labor-intensive manufacture of radiators. The present invention aims to provide a simpler radiator in this regard.
The radiator according to the invention is characterized in that at least one end face of the radiator is welded to a cover which is designed as a part that connects the flat tubes at the end and is freely continuous inside, the cover forming the end face and part of one flat side of the flat tubes.
The subject matter of the invention is then explained using two figures, for example. These represent, purely schematically and in perspective, part of a radiator composed of flat tubes in a cutout with an angular end profile.
The flat tubes 1 are provided with an oblique cut 3 at their end, the cutting plane being at an angle deviating from 90 ° to the flat tube longitudinal axis 18. The flat tubes 1 lying one above the other are welded on their narrow sides 9 and 10. In this way, superimposed openings 5 of the flat tubes 1 with an overall outer edge 7 are created. The longitudinal sides of the individual openings 5 are denoted by 12 and 13, respectively. In order to form a continuous channel 22 at the obliquely cut ends of the flat tubes 1, an angle rail 15, which is closed on its end faces, is welded to the flat tubes 1 along the outer edge 7. This creates a closed radiator, the end of which, formed by the angle rail 15, defines the continuous channel 22 which connects the interiors of the flat tubes with one another.
In the example shown in FIG. 1, the welded-on end cover is designed as an angle rail 15. However, other shapes can also be selected, for example a U-rail 19, preferably with unequal leg lengths, which has the effect that one main side 20 of the flat tubes protrudes like a bay at the end, as can be seen schematically in FIG. 2. One side 21 of the end cover 19 forms the front wall of the radiator, while the other, flat (FIG. 1) or offset (FIG. 2), defines part of one flat side 20 of the radiator.
The production of such a radiator is extremely simple and practical.
