Abstract
Description
Die Erfindung betrifft ein Wärmetauscherrohr mit einer im Querschnitt geschlossenen Außenwandung, die aus einem verformbaren Bandmaterial gebildet ist.The The invention relates to a heat exchanger tube with a closed outer wall in cross-section, consisting of a deformable Band material is formed.
Wärmetauscherrohre mit mehreren Kammern, die auch als Mehrkammerrohre bezeichnet werden, können als Strangpressprofil oder als Sickenrohr mit einer gelöteten Sicke ausgeführt sein.Heat exchanger tubes with several chambers, which are also called multi-chamber pipes, can as an extruded profile or as a bead tube with a soldered bead accomplished be.
Aufgabe der Erfindung ist es, ein Wärmetauscherrohr mit einer im Querschnitt geschlossenen Außenwandung, die aus einem verformbaren Bandmaterial gebildet ist, zu schaffen, das trotz einer geringen Wandstärke eine hohe Festigkeit aufweist.task The invention is a heat exchanger tube with a closed outer wall in cross-section, consisting of a deformable Band material is formed to create, despite a low Wall thickness has a high strength.
Die Aufgabe ist bei einem Wärmetauscherrohr mit einer im Querschnitt geschlossenen Außenwandung, die aus einem verformbaren Bandmaterial gebildet ist, dadurch gelöst, dass ein Abschnitt des Bandmaterials im Inneren des geschlossenen Querschnitts angeordnet und so verformt ist, dass sich innerhalb der Außenwandung mehrere Kammern ergeben. Im Unterschied zu herkömmlichen Sickenrohren wird die Außenwandung bei dem erfindungsgemäßen Wärmetauscherrohr nicht verformt. Der verformte Bandabschnitt im Inneren des geschlossenen Querschnitts dient zum einen dazu, das Wärmetauscherrohr in mehrere Kammern zu unterteilen. Darüber hinaus dient der verformte Bandabschnitt im Inneren des geschlossenen Querschnitts dazu, die Außenwand zu verstärken.The Task is with a heat exchanger tube with a closed outer wall in cross-section, consisting of a deformable Band material is formed, achieved by a portion of the strip material arranged inside the closed cross section and so deformed is that within the outer wall result in several chambers. In contrast to conventional bead pipes is the outer wall in the heat exchanger tube according to the invention not deformed. The deformed band section inside the closed cross section serves on the one hand, the heat exchanger tube to divide into several chambers. In addition, the deformed serves Band section inside the closed cross section to the, outer wall to reinforce.

Es ist auch möglich, den Abschnitt des Bandmaterials im Inneren des geschlossenen Querschnitts mit der Außenwandung zu verschweißen.One Another preferred embodiment of the heat exchanger tube is characterized in that the portion of the strip material inside the closed cross-section with the outer wall soldered is. It is also possible, the portion of the strip material inside the closed cross section with the outer wall to weld.
Ein weiteres bevorzugtes Ausführungsbeispiel des Wärmetauscherrohrs ist dadurch gekennzeichnet, dass das Bandmaterial auf mindestens einer Seite mit Lotmaterial beschichtet ist. Vorzugsweise ist die Außenseite des Bandmaterials lotplattiert. Die Innenseite des Bandmaterials ist vorzugsweise lot-, opfer-, schutz- oder unplattiert.One Another preferred embodiment of the heat exchanger tube is characterized in that the band material on at least one side is coated with solder material. Preferably, the outside Lotplattiert the band material. The inside of the band material is preferably lot, sacrificial, protective or unplated.
Ein weiteres bevorzugtes Ausführungsbeispiel des Wärmetauscherrohrs ist dadurch gekennzeichnet, dass der Abschnitt des Bandmaterials im Inneren des geschlossenen Querschnitts mit Vertiefungen/Erhöhungen ausgestattet ist. Die Vertiefungen/Erhöhungen können zum Beispiel die Gestalt von Näpfen oder Noppen aufweisen und dienen dazu, den Wärmeübergang zu verbessern.One Another preferred embodiment of the heat exchanger tube is characterized in that the portion of the strip material inside the closed cross-section with recesses / elevations is. The depressions / elevations can for example, the shape of cups or nubs and serve to improve the heat transfer.
Ein weiteres bevorzugtes Ausführungsbeispiel des Wärmetauscherrohrs ist dadurch gekennzeichnet, dass die Außenwandung einen im Wesentlichen rechteckigen Querschnitt aufweist.One Another preferred embodiment of the heat exchanger tube is characterized in that the outer wall is a substantially has rectangular cross-section.
Gemäß einem weiteren Ausführungsbeispiel ist der Querschnitt der Außenwandung an zwei Seiten konvex nach außen gekrümmt.According to one Another embodiment is the cross section of the outer wall on two sides convex to the outside curved.
Die Erfindung betrifft auch einen Wärmetauscher mit einem vorab beschriebenen Wärmetauscherrohr.The The invention also relates to a heat exchanger with a heat exchanger tube described above.

Erfindung wird aus dem Bandmaterial
Vorzugsweise ist das Bandmaterial auf der Innenseite lot-, schutz-, opfer- oder unplattiert. Auf der Außenseite ist das Bandmaterial vorzugsweise lotplattiert. Mit dem beschriebenen Verfahren können Mehrkammerrohre aus Materialien hergestellt werden, die nicht oder nur schwer extrudierbar sind. Zudem kann durch die Verwendung von Rohrbandmaterial mit höherer Festigkeit eine kleinere Wandstärke realisiert werden als bei herkömmlichen Mehrkammerrohren.Preferably the tape material on the inside is lot, protective, sacrificial or unplated. On the outside the band material is preferably solder plated. With the described Procedures can multi-chamber pipes made from materials that are difficult or impossible to extrude are. In addition, by the use of pipe tape material with higher strength realized a smaller wall thickness be considered conventional Multi-chamber tubes.
