2 Größenordnung von etwa 1000 kcal/m h, wobei Werkstoffe, insbesondere Kunststoffe verwendet werden können, deren Wärmeleitfähigkeit und deren Temperaturfestigkeit (letztere bezogen auf etwa 100 grd) beide etwa 100 mal kleiner sind als die von Metallen, welche seither ausschliesslich zum Aufbau solcher Wärmeaustauschelemente verwendet worden sind.2 order of magnitude of about 1000 kcal / m h, whereby materials, In particular, plastics can be used, their thermal conductivity and their temperature resistance (the latter based on about 100 degrees) are both about 100 times smaller than that of metals, which has since been used exclusively have been used to construct such heat exchange elements.

Eine weitere Forderung, die der Gegenstand der Erfindung für die erfolgreiche Anwendung in der Praxis erfüllen muß, ist die statische Formstabilität. Hiermit ist gemeint, daß das Wärmeaustauschelement zumindest in einer Richtung seines Querschnittes ein so großes Widerstandsmoment besitzen muß, daß es an seinen Enden eingespannt oder aufgelegt in der Lage ist, ohne nennenswerte Durchbiegung freitragend größere Längen (z.B. mehrere Meter) zu überbrücken und dabei außer seinem Eigengewicht auch noch Kräfte aufzunehmen, die von einem strömenden Medium herrühren.Another requirement that the subject invention meet for successful use in practice must is the static dimensional stability. This means that the heat exchange element at least in one Direction of its cross section must have such a large section modulus that it is clamped at its ends or when placed on top, is able to carry longer unsupported lengths (e.g. several meters) without significant deflection to bridge and besides its own weight also absorb forces from a flowing medium originate.

Schliesslich ist es aus Gründen der Wirtschaftlichkeit noch unerläßlich, daß das Wärmeaustauschelement mit einem Minimum von Werkstoff- und Zeitaufwand auf einfachen, konventionellen Maschinen (z.B. Extrudern) hergestellt werden kann.Finally, for reasons of economy, it is still essential that the heat exchange element with a minimum of material and time expenditure on simple, conventional machines (e.g. extruders) can be produced.

All die vorgenannten Bedingungen werden erfindungsgemäß dadurch erreicht, daß eine Vielzahl dünner und dünnwandiger Rohrprofile, die durch kurze Stege miteinander verbunden sind, in einer Ebene, die durch alle Rohrprofil-Mittelpunkte und durch die Mitte aller Stege hindurchgellt, angeordnet sind und diesesAll of the aforementioned conditions are in accordance with the present invention achieved in that a large number of thin and thin-walled tubular profiles, which are connected by short webs are connected, in a plane passing through all pipe profile center points and through the center of all Bars through, are arranged and this

Die Erfindung wird anhand der Abbildungen näher erläutert.The invention is explained in more detail with reference to the figures.

Fig. 1 zeigt ein Wärmeaustauschelement gemäß der Erfindung in schräger Parallelprojektion und etwa natürlicher Größe. Die Rohrprofile (1) sind mit den Verbindungsstegen (2) verbunden. Das ganze Element wird zweckmäßig in einem Stück aus einem entsprechend geformten Mundstück extrudiert. Bei der meist gegebenen geringen Werkstoff-Festigkeit muß die Rohrwandstärke in der Größenordnung von 1/10. des Rohrdurchmessers liegen. Infolge der geringen Wärmeleitfähigkeit des Werkstoffes sollte weiterhin die Rohrwandstärke selbst in der Größenordnung von etwa 1 ram gehalten werden, sodaß durch die vorgegebenen Begrenzungen sich die Gesamtabmessungen zwangsläufig innerhalb eines eng begrenzten Rahmens bewegen. Aus wirtschaftlichen Gründen ist auch die Länge der Stege eine dem Rohrdurchmesser zugeordnete Größe, die in der Regel gleich oder kleiner als der Rohrdurchmesser ausgeführt werden wird. Bei einer Übereinanderanordnung von z.B. 10 oder mehr Rohrprofilen ergeben sich für die Achsrichtung der Übereinanderanordnung Widerstandsmomente, welche freitragende Längen von mehreren Metern zulassen,Fig. 1 shows a heat exchange element according to the invention in an oblique parallel projection and approximately natural size. The pipe profiles (1) are connected to the connecting webs (2). The whole The element is expediently extruded in one piece from a correspondingly shaped mouthpiece. With the mostly given low material strength, the pipe wall thickness must be of the order of magnitude from 1/10. of the pipe diameter. Due to the low thermal conductivity of the material should continue to be kept the pipe wall thickness itself in the order of about 1 ram, so that through the given limitations the overall dimensions inevitably within a narrowly limited range Move the frame. For economic reasons, the length of the webs is also one of the pipe diameter assigned size, which is usually made equal to or smaller than the pipe diameter. If, for example, 10 or more pipe profiles are arranged one above the other, this results in the axial direction the stacking resistance moments, which allow unsupported lengths of several meters,

Fig. 2 zeigt in schräger Parallelprojektion die Zusammenfassung von mehreren Elementen nach Fig. 1 durch Abstandsleisten (3), welche duöch Verkleben, Verschwüssen oder durch mechanische Befestigungen wie Zuganker mit den Elementen verbunden sind. Durch Hebeneinanderanordnung zahlreicher Elemente ergibt sich ein nach allen Achsrichtungen hin hohes Widerstandsmoment für eine derartige Sandwich-Bauweise. FIG. 2 shows the combination of several elements according to FIG. 1 in an oblique parallel projection by means of spacer strips (3), which can be glued, welded or by mechanical fastenings how tie rods are connected to the elements. By arranging numerous elements one next to the other This results in a high section modulus in all axial directions for such a sandwich construction.
