Mit Rippen versehenes Rohr für Wärmeaustauscher Die Erfindung bezieht sich auf mit Rippen versehene Rohre für Wärmeaustauscher, wobei für Rohre und Rippen verschiedene Metalle verwendet werden, z. B. Kupfer oder eine Kupferlegierung für die Rohre und Aluminium oder eine Aluminiumlegierung für die Rippen.Finned Tube for Heat Exchangers The invention relates to refer to finned tubes for heat exchangers, being for tubes and fins various metals can be used, e.g. B. copper or a copper alloy for the tubes and aluminum or an aluminum alloy for the fins.

Gemäß der Erfindung sind die Rohre mit Zink oder einem äquivalenten Metall, z. B. Cadmium, an der Außenseite plattiert, um eine elektrolytische Wirkung mit dem Metall der Rippen zu vermeiden.According to the invention, the pipes are made with zinc or an equivalent Metal, e.g. B. cadmium, plated on the outside to have an electrolytic effect to avoid using the metal of the ribs.

Weitere Vorteile und Einzelheiten der Erfindung ergeben sich aus der folgenden Beschreibung von Ausführungsbeispielen an Hand der Zeichnung.Further advantages and details of the invention emerge from the following description of exemplary embodiments with reference to the drawing.

In der Zeichnung zeigen : Fig. 1 einen Längsschnitt durch ein erfindungsgemäß ausgebildetes mit Rippen versehenes Rohr, Fig. 2 einen Längsschnitt eines anderen Ausführungsbeispiels eines erfindungsgemäßen mit Rippen versehenen Rohres.In the drawing: FIG. 1 shows a longitudinal section through a device according to the invention formed tube provided with finned, Fig. 2 is a longitudinal section of another Embodiment of a tube provided with ribs according to the invention.

Gemäß dem Ausführungsbeispiel nach Fig. 1 ist ein Rohr 1 aus Kupfer, Messing, Kupfer-Nickel oder irgendeiner anderen geeigneten Kupferlegierung auf der Außenseite X mit Zink oder einem äquivalenten Metall plattiert und mit einer die Rippen 3 tragenden Blechhülse 2 überzogen. Die Blechhülse und die Rippen bestehen aus Aluminium oder aus einer Aluminiumlegierung.According to the embodiment of FIG. 1, a pipe 1 made of copper, Brass, cupro-nickel or any other suitable copper alloy on the Outside X plated with zinc or an equivalent metal and with a die Ribs 3 supporting sheet metal sleeve 2 covered. The sheet metal sleeve and the ribs exist made of aluminum or an aluminum alloy.

Bei dem Ausführungsbeispiel gemäß Fig. 2 entspricht das Rohr 1 vollständig dem in Fig. 1 dargestellten Rohr. Jedoch werden hierbei die Rippen 3 zwischen den Stirnseiten von Distanzringen 4 gehalten, die auf der zinkplattierten Oberfläche X des Rohres 1 aufgeschoben sind. Die Distanzringe 4 bestehen auch aus Aluminium oder aus einer Aluminiumlegierung.In the embodiment according to FIG. 2, the tube 1 corresponds completely the tube shown in FIG. However, here the ribs 3 between the Front sides of spacer rings 4 held on the zinc-plated surface X of the tube 1 are pushed. The spacer rings 4 are also made of aluminum or from an aluminum alloy.

Die gemäß der Erfindung ausgebildeten, mit Rippen versehenen Rohre haben ausgezeichnete Wärmeübertragungseigenschaften und weisen gegen einen hohen Widerstand ober einer elektrolytischen Korrosion auf.The finned tubes formed in accordance with the invention have excellent heat transfer properties and show against a high Resistance to electrolytic corrosion.
