Description

Die Erfindung betrifft ein Einbauelement zum Einbau in einen von einem Fluid durchströmbaren Hohlraum, beispielsweise zum Einbau in einen Rieselkühler, wie Kühlturm oder dergleichen.The invention relates to a built-in element for installation in a cavity through which a fluid can flow, for example for installation in a trickle cooler, such as a cooling tower or the like.

Einbauelemente für Rieselkühler sind in diversen Ausgestaltungen bekannt. Ausschlaggebend für derartige Einbauelemente ist beispielsweise einerseits eine gewisse Verwirbelung und Führung des Kühlmediums, beispielsweise Luft, und andererseits eine relativ große Verweildauer und Oberfläche des zu kühlenden Fluids, wie beispielsweise Wasser. Ein Beispiel für ein Rieselkühler ist der Kühlturm eines Kraftwerks. Hierbei werden als Einbauelemente gewellte Kunststofffolienpakete oder Pakete aus gewellten Kunststoffgittermatten eingesetzt, durch die das oben in den Kühlturm eingesprühte zu kühlende Fluid, nämlich Wasser, tropfenförmig nach unten hindurch tritt und an den Folien bzw. Gitterstäben unter Vergrößerung seiner Fläche entlang strömt und in Kontakt mit der aufgrund der Kaminwirkung erfolgenden Kühlluftströmung gelangt und gekühlt wird.Built-in elements for trickle coolers are known in various configurations. Decisive for such installation elements, for example, on the one hand, a certain turbulence and guidance of the cooling medium, for example air, and on the other hand, a relatively large residence time and surface of the fluid to be cooled, such as water. An example of a trickle cooler is the cooling tower of a power plant. In this case, corrugated plastic film packages or packages of corrugated plastic lattice mats are used as installation elements, through which the top of the cooling tower sprayed fluid to be cooled, namely water, drop-shaped down passes and flows on the films or bars under magnification of its surface along and in contact with which takes place due to the chimney effect cooling air flow and is cooled.

Beispiele für derartige Einbauelemente finden sich in DE-A-198 19 945 , DE-A-197 33 480 und US-B-6 241 222 . In EP-A-0 825 407 ist ein Einbauelement gemäß Oberbegriff von Anspruch 1 mit Gittermatten beschrieben, die trapezförmige Erhebungen und Gitterverstrebungen aufweisen.Examples of such installation elements can be found in DE-A-198 19 945 . DE-A-197 33 480 and US-B-6,241,222 , In EP-A-0 825 407 a mounting element according to the preamble of claim 1 is described with grid mats having trapezoidal elevations and grid struts.

Der Erfindung liegt die Aufgabe zugrunde, ein alternatives Einbauelement für einen von einem Fluid durchströmbaren Hohlraum zu schaffen, das sich durch einen verbesserten Wirkungsgrad bei relativ geringem Materialeinsatz auszeichnet.The invention has for its object to provide an alternative installation element for a permeable by a fluid cavity, which is characterized by improved efficiency with relatively low material usage.

Zur Lösung dieser Aufgabe wird mit der Erfindung ein Einbauelement für einen von einem Fluid durchströmbaren Hohlraum vorgeschlagen, wie beispielsweise einen Kühlturm, wobei das Einbauelement versehen ist mit den Merkmalen des Anspruchs 1; einzelne Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.To solve this problem, the invention proposes a built-in element for a cavity through which a fluid can flow, for example a cooling tower, the installation element being provided with the features of claim 1; individual embodiments of the invention are the subject of the dependent claims.

Das erfindungsgemäße Einbauelement weist mehrere aneinander liegende geformte Kunststoffmatten auf, die eine Gitterstruktur aufweisen und mit mehreren nebeneinander liegenden Halbröhrenabschnitten versehen sind. Jeder Halbröhrenabschnitt weist dabei quer zu seiner Längserstreckung verlaufende Streben mit von diesen in Längsrichtung der Halbröhrenabschnitte abstehenden Zapfen mit wiederum von diesen abstehenden Vorsprüngen auf. Die Halbröhrenabschnitte zweier benachbarter Kunststoffmatten bilden je nach Relativlage dieser beiden Kunststoffmatten einzelne Röhren, die in gewisser Weise der Luftführung dienen. Über die verzweigten Verstrebungen kommt es zu einer Verteilung des zu kühlenden Fluids und beim Entlangtropfen an dem Einbauelement zu einer fortdauernden Zerteilung einzelner größerer Tropfen in kleinere Tropfen. Durch in Längsrichtung der Halbröhrenabschnitte verlaufende Verstrebungen wird dem Einbauelement die notwendige Stabilität verliehen. Die Kunststoffmatten eines Einbauelements (Kunststoffmattenpakets) werden durch quer zur Längserstreckung der Röhrenabschnitte verlaufende Stangen untereinander zusammengehalten, wodurch das gesamte Paket weitere Stabilität erhält. Zusätzlich können die aneinander liegenden Kunststoffmatten untereinander kraftschlussig (formschlüssig, stoffschlüssig oder reibschlüssig) miteinander verbunden sein. Hierzu eignen sich Zapfen-Loch-Verbindungselemente, kaltverformte oder rastend ineinander greifende Verbindungselemente oder Verschweißungen bzw. Verklebungen.The installation element according to the invention has a plurality of contiguous molded plastic mats, which have a grid structure and are provided with a plurality of adjacent half-tube sections. Each half-tube section has struts extending transversely to its longitudinal extension, with pins protruding therefrom in the longitudinal direction of the half-tube sections, with projections projecting therefrom in turn. Depending on the relative position of these two plastic mats, the half-tube sections of two adjacent plastic mats form individual tubes, which in a certain way serve to guide the air. About the branched struts, there is a distribution of the fluid to be cooled and the drainage on the mounting element to a continuous division of individual larger drops into smaller drops. By extending in the longitudinal direction of the half tube sections struts the installation element is given the necessary stability. The plastic mats of a built-in element (plastic mat package) are held together by extending transversely to the longitudinal extent of the tube sections rods with each other, whereby the entire package receives further stability. In addition, the juxtaposed plastic mats can be mutually connected to each other frictionally (positively, cohesively or frictionally). For this purpose, pin-hole fasteners, cold-formed or latching interlocking fasteners or welds or bonds are suitable.

Zur Erzielung einer gewissen Verwirbelung des Kuhlmediums (beispielsweise Luft) innerhalb der Einbauelemente ist es zweckmäßig, wenn jede Kunststoffmatte mehrere in Längserstreckung der Halbröhrenabschnitte aufeinander folgende und quer zueinander versetzte Halbröhrenabschnitte aufweist. Zweckmäßigerweise beträgt der Versatz etwa die Hälfte der Breite der Halbröhrenabschnitte. Die gegeneinander versetzten Halbröhrenabschnitte befinden sich somit in etwa "auf Lücke" zueinander.To achieve a certain turbulence of the Kuhlmediums (for example, air) within the mounting elements, it is expedient if each plastic mat has a plurality of in the longitudinal extension of the half-tube sections successive and transversely offset half-tube sections. Conveniently, the offset is about half the width of the half tube sections. The staggered half tube sections are thus approximately "in gap" to each other.

Die axiale Erstreckungen (Länge) der einzelnen in Längsrichtung aufeinander folgenden und seitlich zueinander versetzten Halbröhrenabschnitte sind zweckmäßigerweise unterschiedlich lang. Dadurch ist es möglich, durch relatives Verdrehen um 180° benachbarter Kunststoffmatten diese unter Überlappung ihrer jeweiligen Halbröhrenabschnitte miteinander zu verbinden. Die Versetzungsbereiche einer Kunststoffmatte, also diejenigen Bereiche, innerhalb derer der Versatz aufeinander folgender Halbröhrenabschnitte einer Kunststoffmatte erfolgt, liegen dann Halbröhrenabschnitten der benachbarten Kunststofffolie gegenüber. Damit erhöht sich des weiteren die Stabilität des gesamten Einbauelements, da in den Versetzungsbereichen schräg verlaufende Verstrebungen die Stabilität der einzelnen Kunststoffmatten beeinträchtigen könnten.The axial extensions (length) of the individual longitudinally successive and laterally offset half-tube sections are expediently of different lengths. This makes it possible, by relative rotation by 180 ° adjacent plastic mats to connect them with overlap of their respective half-tube sections together. The offset areas of a plastic mat, ie those areas within which the offset of successive half-tube sections of a plastic mat takes place, are then opposite to half-tube sections of the adjacent plastic film. This further increases the stability of the entire installation element, since in the displacement areas inclined struts could affect the stability of the individual plastic mats.

In vorteilhafter Weiterbildung der Erfindung ist vorgesehen, dass einzelne Bereiche einer Kunststoffmatte statt einer Streben- oder Gitterstruktur zur Ober- bzw. Unterseite der Kunststoffmatte hin geschlossen sind. Dies erfolgt durch den Verschluss von von Streben eingeschlossenen Bereichen der Kunststoffmatte, die vorzugsweise innerhalb der Ubergangsabschnitte zwischen aufeinander folgenden und seitlich gegeneinander versetzten Halbröhrenabschnitten angeordnet sind. Hierdurch kommt es zu einer zum Teil zwangsweisen Führung des Luftstroms durch die Einbauelemente. Diese teilweise Zwangsführung wirkt sich, wie sich durch Versuche herausgestellt hat, vorteilhaft auf den Wirkungsgrad des Einbauelements aus.In an advantageous embodiment of the invention, it is provided that individual areas of a plastic mat instead of a strut or grid structure to the top or bottom of the plastic mat are closed. This is done by the closure of struts enclosed areas of the plastic mat, which are preferably arranged within the transition sections between successive and laterally staggered half tube sections. This leads to a partially forced guidance of the air flow through the mounting elements. This partial positive guidance affects, as has been found by experiments, advantageous to the efficiency of the mounting element.

Die Halbröhrenabschnitte der Kunststoffmatten des erfindungsgemäßen Einbauelements können grundsätzlich jede mögliche Querschnittsform aufweisen. Vorzugsweise bieten sich Halbröhrenabschnitte mit Halbrundform, dreieckiger oder mehreckiger Form an.The half-tube sections of the plastic mats of the installation element according to the invention may in principle have any possible cross-sectional shape. Preferably, half-tube sections with a semi-circular, triangular or polygonal shape are suitable.

Eine perspektivische Darstellung eines erfindungsgemäßen Einbauelements 10, das aus mehreren nebeneinander angeordneten geformten Kunststoffmatten 12 mit mehreren nebeneinander liegenden und seitlich zueinander versetzten Halbröhrenabschnitten 14,16 und 18 sowie mit mehreren endseitigen Viertelröhrenabschnitten 20 und 22 gemäß Fig. 2 aufgebaut ist, ist in Fig. 1 dargestellt. Benachbarte mit Gitter- oder Strebenstrukturen versehene Kunststoffmatten 12 sind jeweils gegeneinander angeordnet, so dass das Einbauelement 10 mehrere Reihen nebeneinander liegender und längs ihrer Erstreckung versetzter Röhren 24 aufweist. Die Kunststoffmatten 12 sind untereinander durch (Zug-)Stangen 25 verbunden, was in Fig. 1 angedeutet ist.A perspective view of a built-in element 10 according to the invention, which consists of a plurality of juxtaposed molded plastic mats 12 with a plurality of juxtaposed and laterally offset to each other half-tube sections 14,16 and 18 and with a plurality of end quarter-tube sections 20 and 22 according to Fig. 2 is built in is Fig. 1 shown. Adjacent plastic mats 12 provided with grid or strut structures are each arranged opposite one another, so that the installation element 10 has a plurality of rows of adjacent tubes 24 offset along their extension. The plastic mats 12 are interconnected by (pull) rods 25, which in Fig. 1 is indicated.

Jede Kunststoffmatte 12 weist zwischen nebeneinander liegenden Halbröhrenabschnitten verlaufende Längsstreben 26,28 und 30 sowie an den Längsrändern verlaufende Randstreben 32 auf. Benachbarte Längsstreben sind untereinander durch bogenförmige Querstreben 34 miteinander verbunden. Von diesen Querstreben 34 ragen in Längsrichtung der Halbröhrenabschnitte Zapfen 36 ab, die ihrerseits wiederum mit abstehenden Vorsprüngen 38 versehen sind.Each plastic mat 12 has longitudinal struts 26, 28 and 30 extending between adjacent half-tube sections and edge struts 32 extending along the longitudinal edges. Adjacent longitudinal struts are interconnected by arcuate transverse struts 34. Of these cross struts 34 protrude in the longitudinal direction of the half-tube sections pin 36, which in turn are provided with protruding projections 38.

Wie anhand von Fig. 2 zu erkennen ist, sind die endseitigen Hafbröhrenabschnitte 14 sowie die endseitigen Viertelröhrenabschnitte 20 gegenüber den mittleren Halbröhrenabschnitten 16 seitlich versetzt zueinander angeordnet, wobei auch die mittleren Halbröhrenabschnitte 16 gegenüber den endseitigen Halbröhrenabschnitten 18 sowie den endseitigen Viertelröhrenabschnitten 22 seitlich versetzt angeordnet sind. Dadurch bilden sich pro Kunststoffmatte 12 zwei Übergangsbereiche 40, in denen die Längsstreben 26 über schräg verlaufend Übergangsstreben 42 und die Längsstreben 28 über schräg verlaufende Übergangsstreben 44 in die Längsstreben 30 übergehen. In diesen Bereichen kann, was aus Gründen der besseren Übersichtlichkeit in Fig 2 nicht angezeichnet ist, der durch die Übergangsstreben 42 bzw. 44 definierte Bereich flächig verschlossen sein. Die Bereiche zwischen den bogenförmigen Querstegen 34 sind hingegen grundsätzlich offen. Aber auch hier ist es grundsätzlich denkbar, wenn einzelne dieser Bereiche verschlossen sind. Auch ist es möglich, dass die von bogenförmigen Querstreben 34 abzweigenden Zapfen 36 beidseitig der Querstreben 34 bzw. bezogen auf benachbarte Querstreben gegeneinander gerichtet sind und dabei eventuell auch ineinander greifen. Zweckmäßig ist es, wenn die Zapfen 36 so, wie in Fig. 2 gezeigt, benachbarte bogenförmige Querstreben 34 nicht untereinander verbinden. Allerdings ist es möglich, dass Verbindungsstreben zwischen benachbarten bogenförmigen Querstreben 34 vorhanden sind. Ferner weisen die endseitigen Halbröhrenabschnitte 14 eine größere axiale Erstreckung als die gegenüberliegenden endseitigen Halbröhrenabschnitte 18 auf. Dies gilt in entsprechender Weise für die endseitigen Viertelröhrenabschnitte 20 und 22.As based on Fig. 2 it can be seen, the end-side Hafbröhrenabschnitte 14 and the end quarter-tube sections 20 are arranged laterally offset from the central half tube sections 16, wherein the central half tube sections 16 are arranged laterally offset relative to the end half tube sections 18 and the end quarter tube sections 22. As a result, two transition regions 40 are formed per plastic mat 12, in which the longitudinal struts 26 merge via obliquely extending transition struts 42 and the longitudinal struts 28 via oblique transition struts 44 into the longitudinal struts 30. In these areas, what's in for better clarity Fig. 2 is not marked, the region defined by the transition struts 42 and 44 area be closed flat. The areas between the arcuate transverse webs 34, however, are basically open. But here, too, it is conceivable in principle, if individual of these areas are closed. It is also possible for the pins 36 branched off from arcuate transverse struts 34 to be directed towards one another on both sides of the transverse struts 34 or relative to adjacent transverse struts and possibly also to engage in one another. It is useful if the pin 36 so as in Fig. 2 shown, adjacent arcuate transverse struts 34 do not interconnect. However, it is possible that connecting struts between adjacent arcuate transverse struts 34 are present. Furthermore, the end-side half-tube sections 14 have a greater axial extent than the opposite end-side half-tube sections 18. This applies correspondingly to the end quarter-tube sections 20 and 22.

Die Fign. 3 und 4 zeigen zwei alternative Möglichkeiten der Zusammensetzung benachbarter gitter- bzw. strebenförmiger Kunststoffmatten 12. Während in der Situation gemäß Fig. 3 die Übergangsbereiche 40 der aneinander liegenden Kunststoffmatten 12 einander gegenüber liegen, sind diese Übergangsbereiche 40 in der Zusammenbausituation gemäß Fig. 4 in axialer Richtung der Halb- und Viertelröhrenabschnitte versetzt zueinander.The FIGS. 3 and 4 show two alternative ways of composing adjacent grid-like plastic mats 12. While in the situation according to Fig. 3 the transition regions 40 of the juxtaposed plastic mats 12 are opposite each other, these transition regions 40 in the assembly situation according to Fig. 4 offset in the axial direction of the half and quarter tube sections to each other.
