Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die vorliegende Erfindung betrifft Wärmeaustauschrohre mit Stegen, die durch seitliche Verlängerungen der die Rohre bildenden Blechstreifen entstehen oder durch zwischengelegte Blechstreifen gebildet werden, die die Oberfläche der Rohre sowie deren Steifigkeit vergrößern.The present invention relates to heat exchange tubes with webs through lateral Extensions of the sheet metal strips forming the tubes are created or by interposed ones Sheet metal strips are formed, which the surface of the pipes and their rigidity enlarge.

In der Anlage sind mehrere Ausführungsformen dargestellt, und zwar:
ίο Fig. ι eine skizzierte Rohransicht mit zwei Stegen,
Several embodiments are shown in the appendix, namely:
ίο Fig. ι a sketched tube view with two webs,

Fig. 2 ein Rohrschnitt mit ungleichförmigen Blechstreifen,Fig. 2 is a pipe section with non-uniform sheet metal strips,

Fig. 3 ein Rohrschnitt mit vergrößerter Innenoberfläche,3 shows a pipe section with an enlarged inner surface,

Fig. 4 ein Rohrschnitt mit gleichförmigen Blechstreifen,4 shows a pipe section with uniform sheet metal strips,

Fig. 5 ein Rohrschnitt mit einem Stege.5 shows a pipe section with a web.

Bei den Rohren Fig. 1, 2 und 4 sind je zwei Blechstreifen verwendet, deren einer Teil α die Rohrwand nur teilweise bildet, während der Teil b über die Verbindungsstelle verlängert ist und den Steg gibt. Die Blechstreifen bei Rohren nach Fig. 1 und 4 sind gleichmäßig gebildet, während bei Rohren nach Fig. 2 und 3 verschieden geformte Blechstreifen Verwendung finden.In the tubes Fig. 1, 2 and 4, two sheet metal strips are used, one part of which α only partially forms the tube wall, while part b is extended over the connection point and gives the web. The sheet metal strips in tubes according to FIGS. 1 and 4 are formed uniformly, while in tubes according to FIGS. 2 and 3 differently shaped sheet metal strips are used.

Wie Fig. 3 zeigt, kann auch die Innenoberfläche der Rohre vergrößert werden, und zwar in der Art, daß entweder gleichgeformte Blechstreifen nach innen gebogen, oder daß zwischen den das Rohr bildenden Blechstreifen gerade Streifen angeordnet werden, die mit einem Ende in das Innere des Rohres reichen. Diese Blechstreifen können, wenn es zweckmäßig erscheint, aus einem anderen Metall als das Rohr selbst sein. Fig. 5 zeigt ein Rohr mit einem Stege aus einem Blechstreifen. Der Querschnitt der Rohre kann rund, oval oder eckig je nach dem Verwendungszwecke sein.As FIG. 3 shows, the inner surface of the tubes can also be enlarged, and in such a way that either identically shaped sheet metal strips are bent inward, or that straight strips are arranged between the sheet metal strips forming the tube, which reach with one end into the inside of the pipe. These sheet metal strips can, though it appears expedient to be made of a different metal than the tube itself. Fig. 5 shows a tube with a web made of a sheet metal strip. The cross section of the tubes can be round, oval or square depending on the purposes.
