Description
Metallener Rohrkörper. Die Erfindung betrifft einen metallenen Rohrkörper, der mehrere in Reihe geschal tete, z. B. neben- oder übereinan;;-r angeord nete Stränge bezw. Schlangenwindungen auf weist.
Namentlich wenn solche als Rippenrohr- wärmeaustauscher, beispielsweise als Rip- penrohrverdampfer für Kältemaschinen, aus gebildete Körper noch im Feuer zu verzinken sind, können derart grosse Spannungen auf treten, dass die Verbindung zwischen den einzelnen Strängen bezw. .Schlangenwindun gen reisst. Die Folge davon ist, dass die Rohr körper undicht und infolgedessen häufig völ lig unbrauchbar werden.
Zwecks Behebung dieser Übelstände ist bei einem metallenen Rohrkörper der erwähn ten Art gemäss der Erfindung mindestens ein Teil benachbarter Stränge bezw. Windungen durch elastische Verbindungsstücke zusam mengehalten. Solche Verbindungsstücke kön nen zweckmässig als gebogene Flacheisen aus gebildet sein.
Auf der beiliegenden Zeichnung ist eine Ausführungsform des Erfindungsgegenstan- des beispielsweise veranschaulicht, und zwar zeigt:
<B><I>Mg.</I></B> 1 einen mehrere übereinander an geordnete, in Reihe geschaltete Stränge auf ,ceisenden Pippenrohrverdampfer einer im übrigen nich4 gezeigten Kältemaschine, Fig. 2 eine Endansicht von Teilen zweier Rohrstränge und eines diese zusammenhal tenden, elastischen Verbindungsstückes, und Fig. 3 stellt eine Seitenansicht der in Fig. 2 gezeigten Teile dar.
In den Figuren bezeichnet 1 mit Rippen 2 versehene, metallene Rohrstränge, die durch Umlenkstücke 3 in Reihe geschaltet werden und zu einem kontinuierlichen Durch laufrohrkörper verbunden sind. In den Fig. 2 und 3 sind die Rippen der Einfachheit halber weggelassen. Um die Spannungen in diesem Rohrkörper 1, 2, 3 zu vermindern, sind die Umlenkstücke 3 und damit auch die Rohr stränge 1 durch elastische Verbindungs stücke, die als gebogene Flacheisen 4 ausge bildet sind, zusammengehalten.
Die Verbin- dungsstücke 4 können infolge ihrer Elastizi tät auftretende Spannungen weitgehend aus gleichen und infolgedessen ein Zerreissen des Rohrkörpers verhindern.
Die Erfindung lässt sich sinngemäss auch anwenden, wenn der Rohrkörper an Stelle von Strängen eine Anzahl von übereinander gelegenen Schlangenwindungen aufweist.
Anstatt zwischen je zwei benachbarten Strängen bezw. Windungen elastische Ver.. bindungsstücke vorzusehen, kann auch nur ein Teil benachbarter Stränge bezw. Windun gen durch elastische Verbindungsstücke zu sammengehalten sein, während ein anderer Teil benachbarter Stränge bezw. Windungen
Metallic tubular body. The invention relates to a metal tubular body, the several scarf ended in series, z. B. next to or above one ;; - r arranged strands respectively. Has coils of snake.
Especially if those as finned tube heat exchangers, for example as finned tube evaporators for refrigeration machines, are to be galvanized from bodies formed in the fire, such high tensions can occur that the connection between the individual strands or. .Snake coils tear. The consequence of this is that the pipe body leaks and, as a result, is often completely unusable.
In order to remedy these inconveniences, at least a portion of adjacent strands BEZW in a metal tubular body of the type Erwähn th according to the invention. Coils held together by elastic connectors. Such connectors can be conveniently formed as a curved flat iron.
An embodiment of the subject matter of the invention is illustrated, for example, in the accompanying drawing, namely:
<B><I>Mg.</I> </B> 1 a plurality of superposed, series-connected strands on, ceisenden pipeline evaporator of an otherwise not shown refrigeration machine, Fig. 2 is an end view of parts of two pipe strings and one of these together, elastic connector, and Fig. 3 shows a side view of the parts shown in Fig. 2.
In the figures, 1 designates with ribs 2, metal pipe strings which are connected in series by deflectors 3 and are connected to a continuous through pipe body. In Figs. 2 and 3, the ribs are omitted for the sake of simplicity. In order to reduce the stresses in this tubular body 1, 2, 3, the deflectors 3 and thus also the pipe strands 1 are held together by elastic connecting pieces that are formed out as bent flat iron 4.
As a result of their elasticity, the connecting pieces 4 can largely equalize the stresses that occur and consequently prevent the tubular body from tearing.
The invention can also be used analogously when the tubular body has a number of coiled windings instead of strands.
Instead of respectively between two adjacent strands. Windings elastic Ver .. to provide connecting pieces, can bezw only part of adjacent strands. Winding conditions to be held together by elastic connectors, while another part of adjacent strands BEZW. Turns
