Description

AUSGEGEBEN AM 8. MÄRZ 1920ISSUED ON MARCH 8, 1920

Die Erfindung betrifft einen zusammengesetzten Rippenkörper für Wärmeaustauschvorrichtungen jener Art, bei welchen Rippen aus U-förmig gebogenen Blechen mit der Querseite ihrer U-Form am Grundkörper befestigt sind. Nach der Erfindung .werden die Rippen am Grundkörper mit Hilfe von Spannringen angepreßt und durch einen im Metallbade hergestellten metallischen Überzug mitThe invention relates to a composite fin body for heat exchange devices the type in which ribs made of U-shaped sheet metal are attached to the base body with the transverse side of their U-shape are. According to the invention, the ribs on the base body with the help of clamping rings pressed and with a metallic coating produced in a metal bath

ίο dem Grundkörper verlötet. Auf diese Weise bleibt im Gegensatz zu den bekannten Wärmeaustauschvorrichtungen, bei denen die Rippen nur Teile von Kanälen bilden, der von den Rippen unterteilte Raum für den Luftzutrittίο soldered to the base body. In this way remains in contrast to the known heat exchange devices in which the fins Only parts of ducts form, the space divided by the ribs for air admission

auch nach den Seiten völlig offen, wodurch zugleich die Reinigung der Rippen erleichtert wird.also completely open on the sides, which also makes it easier to clean the ribs will.

Die Zeichnung zeigt Ausführungsbeispiele des Erfindungsgegenstandes. Die Fig. ι und 2 zeigen in vertikalem Längsschnitt und im Querschnitt einen gefäßförmigen Rippenkörper mit einer Gruppe von Rippen. Die Fig. 3 bis 6 zeigen die Herstellungsweise der Rippen. Fig. 7 zeigt den Querschnitt durch ein Rohr, welches mit drei Gruppen von Blechrippen ausgestattet ist.The drawing shows exemplary embodiments of the subject matter of the invention. The Fig. Ι and 2 show in vertical longitudinal section and in cross section a vessel-shaped rib body with a group of ribs. FIGS. 3 to 6 show the manner in which the ribs are manufactured. Fig. 7 shows the cross section through a tube, which with three groups of sheet metal ribs Is provided.

Nach Fig. 1 ist der aus Schmiedeeisen gepreßte Topf ι, welcher mittels des Deckels 2According to FIG. 1, the wrought iron pot is ι, which by means of the lid 2

• abgeschlossen ist, mit U-förmigen Rippen 3 versehen. Diese Rippen werden aus einem Blech herausgestanzt und haben vorerst die in Fig. 3 ersichtliche Form. Daran befinden sich bereits Aussparungen 4 bis 11, welche zur Aufnahme der Spannringe dienen. Aus der in Fig. 3 ersichtlichen platten Form wird alsdann das Blech um die Linien a-b und c-i um 90 ° herausgebogen, wodurch die fertige Rippe mit U-förmigem Querschnitt entsteht; Fig. 4 ist eine Vorder-, Fig. 5 eine Seiten- und Fig. 6 eine Oberansicht derselben. In den Fig. 1 und 2 ist gezeigt, wie zwölf derartiger Rippen in gleichen Abständen um das j Gefäß ι herum angeordnet sind. Sie werden durch innere Spannringe 12 und 13 und äußere Spannringe 14 und 15 an den Grundkörper 1 angepreßt. Die Spannringe selbst, die in Fig. 8 und 9 dargestellt sind, haben entsprechende Einschnitte, so daß sie die Lage der U-Rippen j genau fixieren. Alsdann wird der so zusammengesetzte Körper in ein Zinkbad getaucht. Das flüssige Zink überzieht nicht nur die ganze äußere Oberfläche des zusammengesetzten Körpers als eine Schutzschicht gegen Rosten und Säureangriff, sondern dringt von beiden Seiten einer jeden Rippe und außerdem durch gemäß Fig. 3 in das Rippenblech eingestanzte Löcher 16 hindurch zwischen die Querseite der Rippen-U-Form und den Grundkörper ι hinein und verlötet auf diese Weise die Rippen 3 mit dem Grundkörper I. Dadurch wird eine für den Wärmeübergang günstige Verbindung geschaffen.• is completed, provided with U-shaped ribs 3. These ribs are punched out of sheet metal and initially have the shape shown in FIG. 3. There are already recesses 4 to 11 on it, which are used to accommodate the clamping rings. From the plate shape shown in FIG. 3, the sheet metal is then bent out by 90 ° around the lines ab and ci, whereby the finished rib with a U-shaped cross-section is produced; Fig. 4 is a front view, Fig. 5 is a side view and Fig. 6 is a top view of the same. In FIGS. 1 and 2 it is shown how twelve such ribs are arranged at equal intervals around the vessel. They are pressed against the base body 1 by inner clamping rings 12 and 13 and outer clamping rings 14 and 15. The clamping rings themselves, which are shown in FIGS. 8 and 9, have corresponding cuts so that they precisely fix the position of the U-ribs j. The body thus assembled is then immersed in a zinc bath. The liquid zinc not only coats the entire outer surface of the composite body as a protective layer against rusting and acid attack, but also penetrates from both sides of each rib and also through holes 16 punched in the rib plate as shown in FIG. 3 between the transverse side of the rib U. -Form and the base body ι in and in this way soldered the ribs 3 to the base body I. This creates a connection that is favorable for heat transfer.

Die Rippen können als Massenartikel hergestellt werden. Ist ein verhältnismäßig langes Rohr mit Rippen zu versehen, so werden mehrere Gruppen U-förmiger Blechrippen auf die Länge des Rohres verteilt. (Unter einer Gruppe sollen die in gleicherThe ribs can be mass-produced. Is a proportionate To provide a long tube with ribs, several groups of U-shaped sheet metal ribs are created distributed over the length of the pipe. (Under a group they should be in the same
