Description

Bei Rippenrohren mit aufgesetzten Rippen kommt es häufig vor, daß die dünnen Blechrippen durch äußere Einwirkungen zerstört werden. Diesem Übel soll dadurch abgeholfen werden, daß an den äußeren Rändern der Rippenbleche durch Umbiegen derselben Verstärkungen geschaffen werden.In finned tubes with attached fins, it often happens that the thin Sheet metal ribs are destroyed by external influences. This is intended to remedy this evil be that on the outer edges of the ribbed plates by bending the same reinforcements are created.

Von bisher bekannten Ausführungen unterscheidet sich die Ausführungsart gemäß derFrom previously known designs, the embodiment differs according to FIG

ίο Erfindung dadurch, daß, während bei jenen nur zwei gegenüberliegende Seiten von viereckigen Rippen rechtwinkelig abgebogen waren, um nach dem Zusammenschieben derselben auf dem Rohr einen, fest abgeschlosEenen Luftkanal für die zwangläufige Führung der zu erwärmenden Luft zu schaffen, bei der vorliegenden Ausführungsart eine Verstärkung der Rippen dadurch geschaffen werden soll, daß der ganze Rand durch Umlegen, desselben einen Verstärkungswulst bekommt, der dem Rohr erst die unbedingt notwendige Haltbarkeit gibt.ίο invention by the fact that while at those only two opposite sides of square ribs bent at right angles after they were pushed together on the tube, they were firmly closed To create air duct for the positive guidance of the air to be heated, in the present embodiment, a reinforcement the ribs should be created by turning the entire edge, the same gets a reinforcing bead, which the pipe is only absolutely necessary Gives durability.

Abb. 2 den Querschnitt.Fig. 2 the cross section.

Das Rohr α ist ein Heiz- oder Kühlrohr, auf dem die Blechrippen b befestigt sind. Zr1 bezeichnet die Stelle, wo die Verstärkung der Rippen durch Umlegen des Randes erfolgt. The tube α is a heating or cooling tube on which the sheet metal fins b are attached. Zr 1 denotes the point where the ribs are reinforced by folding the edge.
