Description

"Aus Einzelkammern bestehender Rohrkörper"."Tubular body consisting of individual chambers".

Die Erfindung bezieht sich auf einen aus mehreren in Längsrichtung sich erstreckenden Kammern bestehender Rohrkörper.The invention relates to one of several in the longitudinal direction extending chambers of existing tubular bodies.

Derartige Rohrkörper sind an sich bekannt. Es handelt sich dabei um die sogenannten Doppelmantelrohre, wie sie beispielsweise zum Transport von Schwerölen, die während ihres Transportes beheizt werden müssen, verwendet werden. Die Doppelmantelrohre sind aber insofern unvorteilhaft, als die Rohrbogen nicht oder nur mit einem erheblichen Fertigungsaufwand als Doppelrohrbögen hergestellt werden können. Darüberhinaus bietet die genaue Distanzierung des Innenrohres gegenüber dem Außenrohr beachtliche Schwierigkeiten.Such tubular bodies are known per se. These are the so-called double-jacket pipes, as they are, for example be used for the transport of heavy fuel oils that have to be heated during their transport. The jacketed pipes but are disadvantageous in that the pipe bends cannot be produced as double pipe bends or can only be produced with considerable manufacturing effort. Furthermore The exact spacing of the inner tube from the outer tube presents considerable difficulties.

Die Aufgabe der Erfindung besteht darin, einen Rohrkbrper zu schaffen, der sich aus einfachen Bauelementen leicht herstellen und auch leicht zu Rohrbogen verarbeiten läßt.The object of the invention is to provide a tubular body to create that can be easily produced from simple components and also easily processed into pipe bends.

Zur Lösung dieser Aufgabe wird vorgeschlagen, daß als mittige Kammer ein Rohr vorgesehen ist, auf dessen Außenseite nierenformartige weitere Rohre angebracht sind, wobei der Krümmungsradius der Auflageflächen der einzelnen Nierenrohre dem äußeren Radius des Mittenrohres entspricht. Neben dem Kreisrohr bietet auch das Nierenformrohr herstellungsmäßig keine besonderen Schwierigkeiten. Ferner ist der aus verschiedenen Rohren unterschiedlicher Querschnittsform zusammengesetzte Rohrkörper leicht zu Rohrbögen zu verarbeiten.To solve this problem it is proposed that as a central Chamber a tube is provided, on the outside of which kidney-shaped further tubes are attached, the radius of curvature the contact surfaces of the individual kidney tubes the outer Corresponds to the radius of the central tube. In addition to the circular tube, the shaped kidney tube also offers nothing special in terms of manufacture Trouble. Furthermore, the tube body composed of various tubes of different cross-sectional shape is easy to process into pipe bends.

Anhand der in der Zeichnung dargestellten einzigen Figur ist der erfindungsgemäße Rohrkörper im Querschnitt an einem Ausf iihrungsbeispiel dargestellt.Based on the single figure shown in the drawing is the tubular body according to the invention in cross section on one Exemplary embodiment shown.

Der erfindungsgemäße Rohrkörper besteht aus einem Mittenrohr 1, auf dessen äußerer Oberfläche in Längsrichtung sich erstreckende nierenformartige Rohre (2/3/^/5) angeordnet sind, die an ihren seitlichen Längsenden (6/7) mit dem Mittenrohr verschweißt sind. Es versteht sich von selbst, daß anstelle der Schweißverbindung auch eine andere Verbindung, z.B. Verklammerung, vorgesehen werden kann. Letztere Befestigungsart ist dann von Vorteil, wenn erhebliche Temperaturunterschiede zwischen dem Mittenrohr 1 und den Nierenformrohren 2 bis 5 vorhanden sind. Bei dem Ausführungsbeispiel, wie es in der Figur dargestellt ist, werden jeweils um 90 versetzte Nierenformrohre verwendet. Die Anzahl der auf der Oberfläche des Mittenrohres 1 angeordneten Nierenformrohre hängt einerseits von der vorhandenen Oberfläche und andererseits von der Intensität des beabsichtigten Wärmeaustausches ab. Die Verwendung von Nierenformrohren ist dabei insofern von Vorteil, als sie eine breite Auflagefläche auf das z.B. zu beheizende Rohr liefern, die für den Wärmeübergang äußerst günstig ist.The tubular body according to the invention consists of a central tube 1, on its outer surface extending in the longitudinal direction kidney-shaped tubes (2/3 / ^ / 5) arranged which are welded to the central tube at their lateral longitudinal ends (6/7). It goes without saying that instead Another connection, e.g. bracing, can also be provided for the welded connection. The latter type of attachment is advantageous when there are significant temperature differences between the central tube 1 and the kidney shaped tubes 2 to 5 are present. In the embodiment as shown in the figure, 90 staggered kidney shaped tubes used. The number of on the Surface of the central tube 1 arranged kidney shaped tubes depends on the one hand on the existing surface and on the other hand on the intensity of the intended heat exchange. The use of kidney shaped tubes is insofar advantageous as they have a wide contact surface on the e.g. To deliver the tube to be heated, which is extremely favorable for the heat transfer.
