Abstract

The heat exchanger is used in cooling towers and similar installations and comprises a number of rectangular section conduits (3) spaced apart and parallel to each other. These are used to convey the water which is to be cooled and each conduit is provided internally with rows of baffle plates (6) forming a serpentine circuit (7,8). The air is conveyed through round section tubes (5) which pass through the conduits from side to side, being at 90 deg. to the axis of each conduit. These tubes are plain and have no external finning, but may be provided with internal baffles to produce turbulence.

Description

Trockenkühlturm mit zumindest annähernd waagerecht Dry cooling tower with at least approximately horizontal

angeordneten Wärmetauschelementen Zusatz zu Patent ... (Patentanm.P 26 12 158.4) Die Erfindung bezieht sich auf einen Trockenkühlturm mit zumindest annähernd waagrecht angeordneten Wärmetauschelementen, die von einem Wärmeübertragungsmittel, insbesondere Wasser, mit im Vergleich zu Luft relativ hohem Wärmeübergangskoeffizienten durchflossen werden, das mittels Luft im indirekten Wärmeaustausch steht, wobei Jedes Wärmetauschelement zwei zumindest annähernd waagrechte, übereinander liegende Platten mit Oeffnungen und zugeordneten Seitenwänden sowie in die Offnungen zumindest hineinragende oder an die Offnungen anschließende, abgedichtete und von Lurt durchströmte Rohre aufweist, nach Pat. arranged heat exchange elements Addition to patent ... (patent registration P. 26 12 158.4) The invention relates to a dry cooling tower with at least approximately horizontally arranged heat exchange elements, which are carried out by a heat transfer medium, especially water, with a relatively high heat transfer coefficient compared to air are traversed, which is in indirect heat exchange by means of air, wherein Each heat exchange element has two at least approximately horizontal, one on top of the other Plates with openings and associated side walls and in the openings at least protruding or adjoining the openings, sealed and flowed through by Lurt Has tubes, according to Pat.

(Patentanm. P 2612 158.4).(Patent Application P 2612 158.4).

Der Erfindung liegt die Aufgabe zugrunde, den Material-und Kostenaufwand für Wärmetauschelemente der vorgenannten Art, die unter einem Druck stehen, der gleich oder gröBer ist als der Umgebungsdruck der Luft, möglichst gering zu halten.The invention is based on the problem of the material and cost expenditure for heat exchange elements of the aforementioned type, which are under a pressure that is equal to or greater than the ambient pressure of the air, to be kept as low as possible.

Diese Aurgabe wird erfindungsgemäß dadurch gelöst, daß die Seitenwände der Wärmetauschelemente biegeweich sind, daß die Rahmenkonstruktion des Kühlturms im Bereich der Wärmetauschelemente biegesteif ist, daß die Wärmetauschelemente mit entsprechendem Zwischenraum untereinander und gegenüber dem Kühlturm angeordnet sind, und daß die Zwischenräume mit einer druckfesten Füllmasse ausgefüllt sind.This aurgabe is achieved according to the invention in that the side walls the heat exchange elements are flexible that the frame construction of the cooling tower in the field of Heat exchange elements is rigid that the heat exchange elements arranged with a corresponding space between each other and opposite the cooling tower are, and that the spaces are filled with a pressure-resistant filling compound.

Die Vorteile der Erfindung ergeben sich aus der Tatsaohe, daß die Seitenwände der Wärmetauschelemente nicht mehr biegesteif ausgeführt werden müssen.The advantages of the invention result from the fact that the Side walls of the heat exchange elements no longer have to be made rigid.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt. Es zeigt: Fig. 1 einen waagrechten Schnitt durch einen Trockenkühlturm, wobei der Schnitt kurz oberhalb der Wärmetauschelemente geführt ist und Fig. 2 einen Ausschnitt eines Mittellängsschnittes durch den KUhlturm.An exemplary embodiment of the invention is shown schematically in the drawing shown. It shows: FIG. 1 a horizontal section through a dry cooling tower, wherein the section is made just above the heat exchange elements and FIG. 2 shows a Section of a central longitudinal section through the cooling tower.

Mit 1 ist der KUhlturm bezeichnet, der im Bereich der über dem Boden mit Abstand im Kühl turm angeordneten Wärmetauschelemente 2 einen quadratischen Querschnitt aufweist. Der Querschnitt kann in diesem Bereich aber auch z.B. rechteckig sein.1 with the cooling tower is referred to, which is in the area above the ground at a distance in the cooling tower arranged heat exchange elements 2 a square Has cross section. The cross-section in this area can also, for example, be rectangular be.

In dieser quadratischen Fläche sind eine Reihe von kastenförmigen Wärmetauschelementen 2 angeordnet, die die quadratische Fläche nahezu voll ausfüllen. Die Rahmenkonstruktion 17 des Kühlturms ist in diesem Bereich zwecks Auflagern der Wärmetauschelemente und zwecks Aufnahme von Horizontalkräften biegesteif ausgebildet. Die genannte biegesteife Rahmenkonstruktion kann z.B. aus Beton gefertigt sein.In this square area are a number of box-shaped ones Arranged heat exchange elements 2, which almost completely fill the square area. The frame structure 17 of the cooling tower is in this area for the purpose of supporting the Heat exchange elements and designed to be rigid for the purpose of absorbing horizontal forces. The above-mentioned rigid frame construction can be made of concrete, for example.

Die Seitenwände 4 der Wärmetauschelemente 2 sind biegeweich ausgebildet. Die Wärmetauschelemente 2 sind im Kühlturm so angeordnet, daß zwischen den Seitenwänden benachbarter Wärmetauschelemente einerseits und zwischen den äußersten, der Innenwand der Rahmenkonstruktion 17 benachbarter Zwischenwänden der Wärmetauschelemente und der Innenwand der Rahmenkonstruktion andererseits Zwischenräume verbleiben.The side walls 4 of the heat exchange elements 2 are flexible educated. The heat exchange elements 2 are arranged in the cooling tower so that between the side walls adjacent heat exchange elements on the one hand and between the outermost, the inner wall the frame structure 17 of adjacent partition walls of the heat exchange elements and the inner wall of the frame structure on the other hand, gaps remain.

Diese Zwischenräume sind mit einer druckfesten Füllmasse 16 ausgefüllt. Die Füllmasse kann z.B. ein druckfester Kunststoffschaum sein. Die Füllmasse sorgt für eine kraftschlüssige Verbindung zwischen den Seitenwänden entsprechender Wärmetauschelemente bzw. zwischen den äußersten Seitenwänden und der Innenwand der Rahmenkonstruktion.These spaces are filled with a pressure-resistant filling compound 16. The filling compound can, for example, be a pressure-resistant plastic foam. The filling compound ensures for a non-positive connection between the side walls of corresponding heat exchange elements or between the outermost side walls and the inner wall of the frame structure.
