Description

Zylindrischer Wärmetauscher mit in zwei oder mehrere konzentrische bzw. ringförmige Teilströme unterteiltem Rohrbündel Wegen der meist großen Anzahl der zu einem Rohrbündel vereinigten Kühl- oder Heizrohre eines zylindrischen Wärmeaustauschers ist es oft erforderlich, das durch das Innere der Rohre strömende Medium in zwei oder mehrere hintereinanderfolgende Ströme zu unterteilen, um eine hohe Strömungsgeschwindigkeit zu erhalten, die für einen guten Wärmeübergang von großer Bedeutung ist. Außer der üblichen Bauweise, das Rohrbündel geradlinig in sogenannte Kreisschnitte zu unterteilen, um zwei oder mehrere Teilströme zu erhalten, sind Ausführungen mit einer Unterteilung des Rohrbündels in konzentrische bzw. ringförmige Teilströme bekannt geworden. Da es üblich ist, die Rohrreihen solcher Rohrbündel versetzt, d. h. nach dem System gleichseitiger Drei:ecke anzuordnen-einerseits um den verfügbaren Raum voll ausnützen zu können, andererseits um eine möglichst einheitliche Strömung des die Außenseite der Rohre umströmenden Mediums zu erreichen -,fällt bei der Anordnung ringförmiger bzw. kreisrunder Trennwände immer eine Anzahl Rohre aus, die von de-in Trennkreis überschnitten werden. Dadurch wird der verfügbare Raum nur unvollkommen mit Rohren ausgefüllt und keine einheitliche Strömung an der Außenseite der Rohre erreicht.Cylindrical heat exchanger with in two or more concentric or ring-shaped partial flows of subdivided tube bundles because of the mostly large number the cooling or heating tubes of a cylindrical heat exchanger combined to form a tube bundle It is often necessary to divide the medium flowing through the interior of the tubes into two or to subdivide several successive streams in order to achieve a high flow velocity to obtain, which is of great importance for good heat transfer. Except the customary construction to divide the tube bundle in a straight line into so-called circular sections, In order to obtain two or more partial flows, versions with a subdivision are available of the tube bundle in concentric or ring-shaped partial flows has become known. There it is customary to offset the rows of tubes of such tube bundles, d. H. according to the system Equilateral three: to arrange corners - on the one hand, to make full use of the available space to be able to, on the other hand, to achieve the most uniform possible flow of the outside of the medium flowing around the pipes - falls in the arrangement more ring-shaped or circular partition walls always consist of a number of pipes, which from de-in Trennkreis be overlapped. This makes the available space imperfect with pipes filled in and no uniform flow achieved on the outside of the tubes.

Bei der Erfindung werden diese Nachteile dadurch vermieden, daß auf den Stirnflächen des Rohrbündels, d. h. auf der Außenfläche der Rohrböden Trennringe in einer der nicht kreisrunden Rohreinteilung angepaßten, d. h. meist sechseckigen Form angeordnet sind, die nach den Vorlagen zu in einen kreisrunden Ansatz auslaufen, mit dem sie sich in oder über entsprechenden kreisrunden Trennwänden in den Vorlagen genau passend und längs beweglich führen. Die Breite des auf dem Rohrboden aufliegenden Randes des Trennringes entspricht dem Raum zwischen den anliegenden Rohrreihen, so daß deren voller Querschnitt frei bleibt. Damit wird erreicht, daß die Rohreinteilung über den ganzen Bündelquerschnitt gleichmäßig beibehalten werden kann und somit neben einer einheitlichen Strömung zwischen den Rohren eine vollkommene Raumausnützung möglich ist. Das Rohrbündel kann in jede beliebige Stellung verdreht eingebaut werden; die Stärke der Dichtungen zwischen den Vorlagen und dem Gehäuse ist ohne Bedeutung, und das beweglich gelagerte Ende des Rohrbündels kann bei Temperaturdifferenzen ungehindert seine Lage in Längsrichtung verändern. Ein Schlupfverlust des durch die Rohre strömenden Mediums ist bei der passenden zylindrischen Führung der Trennringe an den Trennwänden der Vorlagen praktisch ausgeschlossen.In the invention, these disadvantages are avoided in that on the end faces of the tube bundle, d. H. Separating rings on the outer surface of the tube sheets in one of the non-circular pipe division adapted, d. H. mostly hexagonal Form are arranged, which expire after the templates in a circular approach, with which they are in or over corresponding circular partitions in the templates guide exactly fitting and longitudinally movable. The width of the resting on the tube sheet The edge of the separating ring corresponds to the space between the adjacent rows of pipes, so that their full cross-section remains free. This ensures that the pipe division can be maintained evenly over the entire bundle cross-section and thus in addition to a uniform flow between the pipes, a complete utilization of space is possible. The tube bundle can be installed rotated in any position; the strength of the seals between the templates and the housing is irrelevant, and the movably mounted end of the tube bundle can withstand temperature differences unhindered change its position in the longitudinal direction. A loss of slippage through the pipes of the flowing medium is with the matching cylindrical guidance of the separating rings practically impossible on the dividing walls of the templates.

Die Zeichnung zeigt den Erfindungsgegenstand in Fig. 1 im Längsschnitt, während Fig. 2 die halbe Ansicht auf den oberen und Fig. 3 auf den unteren Rohrboden zeigt.The drawing shows the subject of the invention in Fig. 1 in longitudinal section, while FIG. 2 shows the half view of the upper tube sheet and FIG. 3 shows the lower tube sheet shows.

Das Kühlergehäuse a ist durch die obere Vorlage b und die untere Vorlage c abgeschlossen. Das Rohrbündel wird durch die in den Rohrböden e und f befestigten und abgedichteten Rohre d gebildet. Der Boden e ist zwischen dem Gehäuse a und der Vorlage b eingespannt und durch Dichtringe g abgedichtet, während der Boden f im Unterteil des Gehäuses a längs beweglich geführt und durch die Dichtringe h gedichtet ist; i, k und m sind die auf den Rohrböden befestigten sechseckigen Trennringe, die mit dem zylindrischen Ansatz in den kreisrunden Trennwänden ia, o und p passend geführt werden. Der Verlauf des beim Stutzen q eintretenden, durch die Rohre d strömenden und beim Stutzen r austretenden Mediums ist durch Pfeile gekennzeichnet, ebenso der Verlauf des anderen, beim Stutzen s eintretenden, um die Rohre d mittels der Leitbleche t geführten und beim Stutzen u austretenden Mediums. Die Entlüftung der oberen Vorlage erfolgt bei v und w. The cooler housing a is closed by the upper template b and the lower template c. The tube bundle is formed by the tubes d fastened and sealed in the tube sheets e and f. The base e is clamped between the housing a and the template b and sealed by sealing rings g, while the base f is guided in the lower part of the housing a so that it can move longitudinally and is sealed by the sealing rings h; i, k and m are the hexagonal separating rings attached to the tube sheets, which are guided with the cylindrical extension in the circular separating walls ia, o and p. The course of the medium entering at nozzle q, flowing through pipes d and exiting at nozzle r is indicated by arrows, as is the course of the other medium entering at nozzle s, guided around tubes d by means of guide plates t and exiting at nozzle u . The upper template is vented at v and w.
