Description

Rohrbündel für mehrere hintereinandergeschaltete Heiz- oder Kühlkörper, zwischen denen das zu erwärmende oder abzukühlende gedium eine Veränderung seiner Dichte erfährt. Zweck der vorliegenden Erfindung ist, ein Rohrbündel zu schaffen, das in ein und derselben Ausführung gestattet, durch Einsetzen des Rohrbündels in entsprechend ausgeführte Gehäuse das zu erwärmende oder abzukühlende Medium auf einfachem, zweifachem oder mehrfachem Wege durch das Rohrbündel zu führen. Es ergibt sich häufig die Notwendigkeit, die gleiche sekundliche Gewichtsmenge eines gasförmigen Mediums der Reihe nach durch mehrere hintereinandergeschaltete Heiz-oder Kühlapparate zu führen, wobei das Medium zwischen den einzelnen Apparaten durch eingeschaltete Maschinen, in denen dasselbe verdichtet wird oder aber arbeitleistend expandiert, eine bedeutende Veränderung seiner Dichte, also auch eine bedeutende Veränderung des sekundlich durchströmenden Volumens erfährt, der, gegenüber die durch Abkühlung oder Erwärmung bewirkte Volumenänderung in den einzelnen Apparaten selbst vernachlässigt werden kann. Mehrere solcher Einzelapparate bilden mit den dazwischengeschalteten Maschinen einen einheitlichen Maschinensatz. Zur Erreichung eines möglichst günstigen Wärmeaustausches ist es nun notwendig, eine bestimmte Durchströmgeschwindigkeit einzuhalten. Andererseits ist es erwünscht, die Rohrbündel in gleicher Konstruktion auszubilden, um dieselben serienweise herstellen zu können, um eine Auswechselbarkeit derselben zu ermöglichen und um mit einem einzigen Reservebündel für den ganzen Maschinensatz auszukommen. Diesen Anforderungen wird erfindungsgemäß dadurch entsprochen, daß das Rohrbündel durch eingebaute Längs- oder Querscheidewände in mehrere Bündelpartien derart unterteilt wird, daß durch Einbau des Bündels in entsprechend ausgeführte Gehäuse das Medium auf einfachem, doppeltem oder mehrfachem Wege durch das Bündel geführt und so die Durchströmgeschwindigkeit der jeweiligen Dichte des Mediums angepaßt wird. Das Rohrbündel ist derart ausgebildet, daß in sämtlichen Strömungslinien eines Teilbündels der Strömung des Mediums der gleiche Widerstand entgegengesetzt und dadurch eine gleichmäßige Ausnutzung der gesamten Kühlfläche gewährleistet wird. Ist der Widerstand nicht in allen Strömungslinien der gleiche, dann sucht sich das Medium den Weg des kleinsten Widerstandes, wodurch ein großer Teil der Rohre in seiner Wirksamkeit stark beeinträchtigt wird.Tube bundle for several heating or cooling elements connected in series, between which the medium to be heated or cooled has a change in it Experience density. The purpose of the present invention is to create a tube bundle, which allows in one and the same design, by inserting the tube bundle in appropriately designed housing on the medium to be heated or cooled single, double or multiple ways to lead through the tube bundle. It results often the need to use the same secondary weight of a gaseous Medium in sequence through several heating or cooling devices connected in series to lead, with the medium switched between the individual apparatuses Machines in which the same is compressed or expanded to perform work, a significant change in its density, so also a significant change of the volume flowing through it, which, on the other hand, experiences that through cooling or heating caused volume change in the individual apparatus itself is neglected can be. Several such individual apparatuses form with those in between Machines a uniform set of machines. To achieve the cheapest possible Heat exchange, it is now necessary to have a certain flow rate to be observed. On the other hand, it is desirable to have the tube bundle in the same construction train in order to be able to manufacture the same in series, in order to be interchangeable to enable the same and around with a single reserve bundle for the whole Machine set get along. According to the invention, these requirements are met by that the tube bundle by built-in longitudinal or transverse partitions into several bundle sections is subdivided in such a way that by incorporating the bundle into appropriately executed Enclose the medium in a single, double or multiple way through the bundle guided and so the flow rate is adapted to the respective density of the medium will. The tube bundle is designed such that one in all flow lines Partial bundle of the flow of the medium opposed to the same resistance and this ensures that the entire cooling surface is used evenly. If the resistance is not the same in all flow lines, then that looks for it Medium the path of least resistance, which puts a large part of the pipes in its effectiveness is severely impaired.

In dem dargestellten Ausführungsbeispiel zeigt Fig. i ein Rohrbündel a, das durch die eingebauten Längswände b in die vier Teilbündel c, d, e, f unterteilt ist. Durch Einbau des Bündels a in die entsprechend ausgeführten Gehäuse g, h, i (Fig. a, 3, q) wird erreicht, daß das Medium durch das gleiche Bündel auf einfachem, zweifachem und vierfachem Wege hindurchgeführt wird. Die viereckige Form des Bündels ergibt in jedem Falle auch bei Ausführung nach Fig. z und 3 den gleichen Strömungswiderstand.In the illustrated embodiment, FIG. 1 shows a tube bundle a, which is divided into the four sub-bundles c, d, e, f by the built-in longitudinal walls b. By installing the bundle a in the correspondingly designed housing g, h, i (Fig. A, 3, q) it is achieved that the medium is passed through the same bundle in one, two and four ways. The square shape of the bundle results in the same flow resistance in each case even in the embodiment according to FIGS.
