Description

Die Erfindung bezieht sich auf einen Lamellenkörper, insbesondere für Gas-Wasserheizer. Bekanntlich schließt bei solchen Geräten der mit Durchlaufrohren versetzte Lamellenkörper einen von einem Mantel gebildeten Heizraum nach oben ab. Die innige, zur Wärmeübertragung erforderliche Verbindung zwischen Lamellenkörper und Heizschachtmantel wird bisher .durch Lötung hergestellt. Der damit verbundene Arbeitsgang ist verhältnismäßig teuer. Der Erfindung liegt die Aufgabe zugrunde, den Arbeitsgang zu verbilligen und das Einlöten des Lamellenkörpers zu vermeiden, ohne auf eine innige wärmeübertragendeVerbindung zu, verzichten.The invention relates to a lamellar body, in particular for gas water heaters. It is known that the one with flow tubes closes in such devices offset lamellar body from a heating space formed by a jacket upwards. The intimate connection between the lamellar body required for heat transfer and heating shaft jacket has been produced by soldering up to now. The associated Operation is relatively expensive. The invention is based on the object to make the operation cheaper and to avoid soldering in the lamellar body, without having to do without an intimate heat-transferring connection.

Dies geschieht erfindungsgemäß' dadurch, daß die an der Heizraumwandung liegenden Kanten der Lamellen abgekantet sind und daß ein Teil des abgekanteten Blechstreifens bei jeder Lamelle zu einem Falzrand hochgebogen ist, der mit der Heizraumwandung durch Falzen verbunden wird. Man kann, um ein gutes Aneinanderschließen der einzelnen Lamellenbleche sicherzustellen, die abgekanteten Blechstreifen und den Falzrand mit einer Ausprägung versehen derart, daß beim Aufeinanderschichten der Lamellen die ausgeprägten Ränder der einen Lamelle über den nicht ausgeprägten Teil des Randes der darunterliegenden Lamelle übergreifen. Es entsteht auf diese Weise ein in sich geschlossener Lamellenkörper, der sich leicht einfalzen läßt.This is done according to the invention 'in that the on the boiler room wall lying edges of the slats are folded and that part of the folded Sheet metal strip is bent up to a rebate edge on each lamella, which with the Heizraumwandung is connected by folding. One can in order to join forces well ensure the individual lamellar sheets, the folded sheet metal strips and the folded edge provided with an expression in such a way that when layered on top of one another of the lamellas the pronounced edges of one lamella over the non-pronounced Reach over part of the edge of the lamella below. It arises on this A self-contained lamellar body that is easy to fold in.

Die Fig. i und 2 zeigen eine Lamelle eines solchen Lamellenblocks als Ausführungsbeispiel der Erfindung. Das aus Kupferblech hergestellte Lamellenblatt i besitzt. mehrere mit einem hochgezogenen Rand versehene Löcher 2, durch die die Durchlaufrohre hindurchgeführt sind.FIGS. I and 2 show a lamella of such a lamella block as an embodiment of the invention. The lamellar sheet made from copper sheet i owns. a plurality of raised rim holes 2 through which the Flow tubes are passed.

An den Rändern des Lamellenblattes i sind schmale Blechstreifen 3 abgekantet. Die unteren Teile des Blechstreifens 3 sind wiederum rechtwinklig abgebogen und bilden einen Falzrand 4.. Die Blechstreifen 3 und die Falzränder 4 sind mit einer Ausprägung 5 versehen und greifen mit den ausgeprägten Teilen über die nicht ausgeprägten' Teile der nächsten gleichartigen Lamelle hinweg. Die Falzränder 4 eines auf diese Weise hergestellten Lamellenpaketes werden mit dem nicht dargestellten Heizschachtmantel zusammengefalzt.Narrow sheet metal strips 3 are located on the edges of the lamella leaf i bevelled. The lower parts of the sheet metal strip 3 are again bent at right angles and form a folded edge 4 .. The sheet metal strips 3 and the folded edges 4 are with provided an expression 5 and engage with the pronounced parts on the not pronounced 'parts of the next similar lamella away. The fold edges 4 a lamella set produced in this way are combined with the one not shown Heating shaft jacket folded together.
