Description

Die Erfindung betrifft ein Kühldeckenelement aus einer Blechplatte und einer Rohrleitung, die auf einer Seite der Blechplatte befestigt ist und sich in einer Ebene über deren Grundfläche in gleichmäßigen Abständen erstreckt, wobei in Abständen zueinander verlaufende, gerade ausgerichtete Strecken der Rohrleitung in an deren Außendurchmesser angepassten Sicken der Blechplatte eingelassen sind.The invention relates to a cooling ceiling element made of a sheet metal plate and a Pipe that is attached to one side of the sheet metal plate and is in one plane extends over their base area at regular intervals, with intervals mutually extending, straight lines of the pipeline in other Corresponding beads of the sheet metal plate are recessed.

Aus derartigen allgemein bekannten Kühldeckenelementen werden Kühldecken hergestellt, welche die Aufgabe haben, vorzugsweise in Verbindung mit einer Quellüftung im Aufenthaltsbereich von Personen anfallende Kühllasten abzuführen. Dazu werden Raumdecken vollständig oder teilweise mit kaltwasserführenden Wärmetauschern belegt, welche die Deckentemperatur unterhalb der Raumtemperatur absenken und halten, so daß man derartige Raumdecken als Kühldecken und die eingesetzten Wärmetauscher als Kühldeckenelemente bezeichnet.Such well-known chilled ceiling elements become chilled ceilings produced, which have the task, preferably in connection with a Discharge source ventilation in the area around people from cooling loads. For this purpose, ceilings are completely or partially covered with cold water Heat exchangers occupied, which the ceiling temperature below room temperature lower and hold, so that such ceilings as chilled ceilings and used heat exchanger referred to as chilled ceiling elements.

Zahlreiche Varianten von Raumdecken, wie beispielsweise offene Rasterdecken, richtungslose Metallangfelddecken oder geschlossene Putzdecken, die auch als Akustikdecken eingebaut werden können, sind bekannt. Da Raumdecken einen architektonisch hohen Stellenwert besitzen, sollen Kühldeckenelemente so gestaltet sein, daß diese die Ausführung der Raumdecken ohne wesentliche Einschränkung der Bauart und Geometrie erlauben.Numerous variants of room ceilings, such as open grid ceilings, directional metal corner ceilings or closed plaster ceilings, which also as Acoustic ceilings can be installed are known. Because ceilings In this way, chilled ceiling elements should be of great architectural importance be that the execution of the ceilings without significant restriction of the Allow design and geometry.

Die bekannten Raumdecken, offenbart beispielsweise in der DE-OS 21 38 667 und in der US 5,033,361, basieren auf einer Anordnung einer Mehrzahl von Rohrleitungen zwischen einem Verteiler- und einem Sammlerrohr. Diese Parallelschaltung von Rohrleitungen ist aufwändig und teuer in der Herstellung, führt zu einer ungleichmäßigen Beaufschlagung der Rohrleitungen und insbesondere häufig zu Undichtigkeiten durch die Vielzahl der notwendigen Anschlüsse.The known room ceilings, disclosed for example in DE-OS 21 38 667 and in US 5,033,361, are based on an arrangement of a plurality of pipelines between a distributor pipe and a collector pipe. This parallel connection of Piping is complex and expensive to manufacture, leading to one uneven loading of the pipelines and especially often too Leaks due to the large number of connections required.

Der Wirkungsgrad eines eingangs beschriebenen Kühldeckenelementes und damit auch der Wirkungsgrad der Kühldecke insgesamt, wird wesentlich beeinflußt durch die Art und Weise der Verbindung zwischen der Blechplatte und der Rohrleitung. Dazu sind Halteprofile der verschiedensten Ausführungsformen allgemein bekannt, die einerseits an der Blechplatte zu befestigen sind und andererseits Teilstücke der Rohrleitung umklammern. Abgesehen davon, daß die Befestigung einer großen Anzahl von Halteprofilen an einer Blechplatte arbeitsaufwendig ist, beschränkt sich der Wärmeübergang auf die Teilflächen der Rohrleitung, welche mit der Blechplatte unmittelbar oder über die Halteprofile zumindest mittelbar in Kontakt gebracht werden.The efficiency of a cooling ceiling element described at the outset and thus The overall efficiency of the cooling ceiling is significantly influenced by the Type of connection between the sheet metal plate and the pipeline. To do this Holding profiles of various embodiments are generally known, on the one hand are to be fastened to the sheet metal plate and, on the other hand, sections of the pipeline clasp. Apart from the fact that the attachment of a large number of Holding profiles on a sheet metal plate is labor-intensive is limited the heat transfer to the partial surfaces of the pipeline, which with the sheet metal plate brought into contact directly or at least indirectly via the holding profiles become.

Der Erfindung liegt die Aufgabe zugrunde, ein Kühldeckenelement der eingangs beschriebenen Art so auszubilden, daß es sich durch eine großflächige unmittelbare Verbindung zwischen der Blechplatte und der Rohrleitung auszeichnet, einfach serienmäßig herzustellen ist und mit einem geringen Aufwand auch noch am Einsatzort variiert werden kann, wobei insbesondere auch die kaltwasserführende Verrohrung einschließlich der Rohrabstände sich den jeweiligen Erfordernissen anpassen lassen.The invention has for its object a cooling ceiling element of the beginning type described so that it is a large area immediate Distinguishes connection between the sheet metal plate and the pipeline, is easy to manufacture in series and with little effort can be varied at the place of use, especially the cold water Piping including the pipe spacing depends on the respective requirements adjust.

Ausgehend von einem Kühldeckenelement der im Oberbegriff des Patentanspruches 1 genannten Art, wird diese Aufgabe erfindungsgemäß durch die im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Merkmale gelöst.Starting from a cooling ceiling element in the preamble of the claim 1 mentioned type, this object is achieved by the in the characterizing Part of claim 1 specified features solved.

Durch die erfindungsgemäße Anordnung von Strecken der Rohrleitung in Sicken der Blechplatte, ergibt sich ein großflächiger Kontakt zwischen der Rohrleitung und der Blechplatte, ohne dazu auf speziell ausgebildete Halteprofile, Spannelemente und dergleichen Hilfsmittel angewiesen zu sein. Es genügt stattdessen, die Blechplatte so zu profilieren, daß vorzugsweise über deren Breite in gleichmäßigen Abständen Sicken vorgesehen sind, die sich durchgehend über die Länge der Blechplatte erstrecken. Dabei kann die Dichte der gerade ausgerichteten Strecken der Rohrleitung in der Weise variiert werden, daß entweder durch jede Sicke oder aber lediglich durch jede zweite, dritte oder in beliebigem Abstand folgende Sicke eine Strecke der Rohrleitung verlegt wird. Durch jede der gleichmäßig über die Grundfläche der Blechplatte verteilt angeordneten Sicken erfährt die Blechplatte eine Aussteifung, die sich insbesondere um eine zur Sickenlängserstreckung senkrechte Achse auswirkt. Dadurch läßt sich die Anzahl der Befestigungsstellen am Kühldeckenelement reduzieren, ohne eine nennenswerte Durchbiegung befürchten zu müssen. Weiterhin kann die Blechplatte in Längs- und Querrichtung zu den Sicken auf die jeweils erforderlichen Abmessungen verkleinert und im so zugeschnittenen Zustand mit einer Rohrleitung ausgestattet werden. So vorbereitet, kann das Kühldeckenelement, z. B. bei einer Rasterdecke, auf vormontierten Querkonsolen einfach aufgelegt oder, z. B. bei einer geschlossenen Putzdecke, gegen die Putzträgerplatte punktuell befestigt werden. Die Enden der Rohrleitung werden so lang bemessen, daß mit handelsüblichen Anschlüssen eine Verbindung mit einer Hauptrohrleitung herstellbar ist. Erfindungsgemäß erstreckt sich mindestens über die Grundfläche der Blechplatte eine Verkleidungsplatte und versperrt den Öffnungsquerschnitt sämtlicher Sicken. The arrangement according to the invention of sections of the pipeline in beads of the sheet metal plate results in a large-area contact between the pipeline and the sheet metal plate, without having to rely on specially designed holding profiles, tensioning elements and similar aids. Instead, it is sufficient to profile the sheet metal plate in such a way that beads are preferably provided over its width at regular intervals, which beads extend continuously over the length of the sheet metal plate. The density of the straight lines of the pipeline can be varied in such a way that a line of the pipeline is laid either through each bead or only through every second, third or any subsequent bead. Through each of the beads, which are evenly distributed over the base area of the sheet metal plate, the sheet metal plate is braced, which has an effect in particular about an axis perpendicular to the longitudinal extension of the bead. As a result, the number of fastening points on the cooling ceiling element can be reduced without having to fear significant deflection. Furthermore, the sheet metal plate can be reduced in the longitudinal and transverse directions to the beads to the dimensions required in each case and can be equipped with a pipeline in the thus cut state. So prepared, the chilled ceiling element, e.g. B. on a grid ceiling, simply placed on pre-assembled cross consoles or, for. B. with a closed plaster ceiling, can be fixed against the plaster base plate. The ends of the pipeline are dimensioned so long that a connection to a main pipeline can be established using commercially available connections. According to the invention, a cladding plate extends at least over the base area of the sheet metal plate and blocks the opening cross section of all the beads.

Bei einer Ausgestaltung der Erfindung weisen die Sicken einen Omega-förmigen Querschnitt auf, so daß sich die Rohrleitung in die Sicken einpressen läßt und unter Klemmkraft darin gehalten wird.In one embodiment of the invention, the beads have an omega shape Cross section on, so that the pipe can be pressed into the beads and under Clamping force is held in it.

In einer weiteren Ausgestaltung der Erfindung sind die gerade ausgerichteten Strecken der Rohrleitung außerhalb der in der Blechplatte vorgesehenen Sicken über bogenförmige Rohrleitungsstücke so miteinander verbunden, daß die Rohrleitung insgesamt mäanderförmig verläuft.In a further embodiment of the invention, the straight lines are the pipeline outside the beads provided in the sheet metal plate arcuate pipe pieces connected so that the pipe overall meandering.

Bei Verwendung einer Verkleidungsplatte erstreckt diese sich vorzugsweise auch über die bogenförmigen Rohrleitungsstücke und deckt diese gleichfalls so ab, daß auch deren Anschlüsse mit verkleidet sind.When using a cladding panel, this preferably also extends over the arcuate pipe pieces and also covers them so that also whose connections are covered with.

Schließlich sieht eine Ausgestaltung der Erfindung noch vor, daß die Blechplatte außerhalb der Sicken mit über die Grundfläche gleichmäßig verteilten Perforationen versehen ist, so daß Schallwellen in den Deckenhohlraum eindringen können und dort absorbiert werden.Finally, an embodiment of the invention provides that the sheet metal plate outside the beads with perforations evenly distributed over the base is provided so that sound waves can penetrate into the ceiling cavity and there be absorbed.

Das Kühldeckenelement besteht im wesentlichen aus einer Blechplatte 1 und einer Rohrleitung 2 sowie einer nicht zwingend erforderlichen Verkleidungsplatte 3.The cooling ceiling element consists essentially of a sheet metal plate 1 and one Pipeline 2 and a cladding plate 3 which is not absolutely necessary.

Die Blechplatte 1 besteht aus einem Aluminiumblech, das in Abständen über seine Breite Ω-förmige Sicken aufweist, die sich durchgehend über die Länge der Blechplatte 1 erstrecken.The sheet metal plate 1 consists of an aluminum sheet, which at intervals over its Has wide Ω-shaped beads that extend continuously over the length of the sheet metal plate 1 extend.

Die Rohrleitung 2 besteht aus flexiblem Kupferrohr oder Weichstahlrohr oder aus flexiblem, diffusionsdichtem Kunststoffrohr und weist gerade Strecken 5 auf, die in den Sicken 4 eingelassen sind und über bogenförmige Rohrleitungsstücke 6 außerhalb der Grundfläche der Blechplatte 1 so miteinander verbunden sind, daß die Rohrleitung 2 insgesamt mäanderförmig verläuft und mit Endstücken 7, 8 in konventioneller Weise an einen nicht dargestellten Vor- bzw. Rücklaufstrang einer kaltwasserführenden Hauptleitung anschließbar ist.The pipe 2 consists of flexible copper pipe or mild steel pipe or flexible, diffusion-proof plastic tube and has straight sections 5 that are embedded in the beads 4 and via curved pipe sections 6 are connected to each other outside the base of the sheet metal plate 1 so that the pipeline 2 is meandering overall and has end pieces 7, 8 in conventionally to a supply or return line, not shown cold water-carrying main line can be connected.

Die Verkleidungsplatte 3, welche in konventioneller Weise mit der Blechplatte verbunden sein kann, besteht gleichfalls aus Aluminium und schließt an ihren Längsseiten mit der Blechplatte 1 bündig ab, während sie über deren Querseiten vorsteht. Mit der Verkleidungsplatte 3 sind daher auch die bogenförmigen Rohrleitungsstücke 6, sowie die Endstücke 7 und 8 mit ihren Anschlüssen verdeckbar.The cladding plate 3, which in a conventional manner with the sheet metal plate can be connected, also consists of aluminum and connects to their Long sides flush with the sheet metal plate 1, while over the transverse sides protrudes. With the cladding plate 3 are therefore the arcuate pipe pieces 6, and the end pieces 7 and 8 with their connections concealable.

Die mäanderförmig verlaufende Rohrleitung 2 läßt sich in die Sicken der Blechplatte 1 einfach einklipsen, sofern die Sicken 4, wie in den Ausführungsbeispielen dargestellt, eine Querschnittskontur mit einer geringfügig kleineren Öffnungsbreite aufweisen als der Außendurchmesser der Rohrleitung 2. The meandering pipeline 2 can be in the beads of the sheet metal plate Simply clip in 1 if the beads 4, as in the exemplary embodiments shown, a cross-sectional contour with a slightly smaller opening width have as the outer diameter of the pipeline 2nd

Werden Kühlelemente in handelsübliche Deckenplatten (z.B. metallische Langfeldkassetten) eingelegt, ist ein guter Kontakt zwischen der Blechplatte 1 des Kühlelements und einer jeweiligen, in den Fig. 3 bis 7 dargestellten Deckenplatte 9 erforderlich, um eine hohe Kühlleistung zu erzielen. Dies ist in der Praxis häufig schwierig, da die Deckenplatte 9 von sich aus bereits eine Durchbiegung aufgrund ihres Eigengewichts aufweist und diese in der Regel aus optischen Gründen nicht weiter vergrößert werden soll.Are cooling elements in commercially available ceiling panels (e.g. metallic linear cassettes) inserted, there is good contact between the sheet metal plate 1 of the cooling element and a respective ceiling plate 9 shown in FIGS. 3 to 7 required to achieve high cooling performance. In practice this is common difficult because the ceiling plate 9 already has a deflection due to itself has its own weight and usually not for optical reasons should be further enlarged.

Es sind Spannbügel bekannt, die das Kühlelement an die Deckenplatte 9 anpressen. Die Vorspannung dieser Bügel muß aber sehr genau auf die Durchbiegung der Deckenplatte 9 abgestimmt sein, um die bereits vorhandene Durchbiegung nicht zu vergrößern. Hinzu kommt, daß diese Vorspannung je nach der Breite der Dekkenplatte 9 variiert werden muß und diese Spannbügel aufgrund der unterschiedlichen herstellungsspezifischen Ausführungen von Umkantungen der Deckenplatte 9 ein spezifisches Verbindungselement zur Deckenplatte 9 benötigen. Dadurch entstehen erhebliche Kosten für Vorversuche bezüglich der Vorspannung und für die Lagerhaltung. Ein weiterer Nachteil ist, daß in der Projektbearbeitung die spezielle Ausführung der Deckenplatte 9 bekannt sein muß.Clamping brackets are known which press the cooling element onto the ceiling plate 9. The bias of this bracket must be very precise on the deflection of the Ceiling plate 9 must be matched to the existing deflection not to enlarge. In addition, this preload depends on the width of the ceiling tile 9 must be varied and this clamp due to the different Manufacturing-specific versions of edging of the ceiling tile 9 need a specific connecting element to the ceiling panel 9. Thereby there are considerable costs for preliminary tests with regard to preload and warehousing. Another disadvantage is that in project processing the special version of the ceiling plate 9 must be known.

Die genannten Nachteile lassen sich vermeiden, wenn das Kühlelement direkt mit der Deckenplatte 9 verbunden wird, wozu beispielsweise die in Figur 3 dargestellte Ausführungsart vorgeschlagen wird.The disadvantages mentioned can be avoided if the cooling element is used directly the ceiling panel 9 is connected, for which purpose, for example, that shown in Figure 3 Execution type is proposed.

Die in den Figuren 1 und 2 dargestellte Verkleidungsplatte 3 ist bei dieser Ausführungsart nicht erforderlich. Die Sicke 4 wird so bemessen, daß sich zwischen dem Kupferrohr 5 und der Deckenplatte 9 ein Hohlraum 10 ergibt, welcher ein elastisches Klebematerial 11, vorzugsweise mit guter Wärmeleitfähigkeit, aufnimmt. Dieses kann in pastöser Form oder als Klebeband aufgebracht werden. Das Klebematerial 11 kann bereits bei der Vorfertigung auf das Kühlelement aufgebracht werden. Auf der Baustelle wird dann die Verbindung mit der Deckenplatte 9, z.B. durch Abziehen eines Schutzstreifens vom Klebematerial 11, vorgenommen. The cladding panel 3 shown in Figures 1 and 2 is in this embodiment not mandatory. The bead 4 is dimensioned so that between the copper tube 5 and the ceiling plate 9 results in a cavity 10, which a elastic adhesive material 11, preferably with good thermal conductivity. This can be applied in pasty form or as an adhesive tape. The Adhesive material 11 can already be applied to the cooling element during prefabrication become. The connection to the ceiling slab is then made at the construction site 9, e.g. by removing a protective strip from the adhesive material 11.

Die Unterbringung des Klebematerials 11 in der Sicke 4 hat den Vorteil, daß kein zusätzliches Material zwischen die Blechplatte 1 und die Deckenplatte 9 gelangt, welches den Wärmeübergang verschlechtert.The accommodation of the adhesive material 11 in the bead 4 has the advantage that none additional material gets between the sheet metal plate 1 and the ceiling plate 9, which worsens the heat transfer.

Es ist nicht erforderlich, das Klebematerial 11 über die gesamte Länge der Sicke 4 aufzutragen. Ein punktueller oder teilstreifenförmiger Auftrag des Klebematerials 11 ist bei entsprechender Klebekraft ausreichend.It is not necessary to apply the adhesive material 11 over the entire length of the bead 4 apply. A selective or partial strip-shaped application of the adhesive material 11 is sufficient with appropriate adhesive strength.

Da über die Blechplatte 1 bereits ein großflächiger Kontakt mit der Deckenplatte 9 besteht, kann auch Klebematerial 11 mit schlechter Wärmeleitfähigkeit verwendet werden. Wird Klebematerial 11 mit guter Wärmeleitfähigkeit verwendet, ergibt sich insofern eine Verbesserung, da gegenüber einer linienförmigen Auflage der Rohrleitung 2 eine breitflächige Übertragungsfläche entsteht.Since there is already extensive contact with the ceiling plate 9 via the sheet metal plate 1 exists, adhesive material 11 with poor thermal conductivity can also be used become. If adhesive material 11 with good thermal conductivity is used, the result is in this respect an improvement, since compared to a linear support of the pipeline 2 A wide-area transmission area is created.

Insgesamt wird durch die Verklebung des Kühlelements mit der Deckenplatte 9 die Stabilität des Gesamtbauteils verbessert und insbesondere die Durchbiegung der Deckenplatte 9 selbst vermindert.Overall, by gluing the cooling element to the ceiling plate 9 Stability of the overall component is improved and in particular the deflection of the Cover plate 9 reduced itself.

Bei einer Ausgestaltung gemäß Figur 3 kann das Klebematerial 11' auch in einer separaten Sicke 12 untergebracht werden. Bei Deckenplatten 9 mit durchgehender Lochung wird ein gewebeartiger Klebestreifen einzusetzen sein, um einen Durchtritt von pastösem Kleber durch die Lochung der Deckenplatte zu vermeiden.3, the adhesive material 11 'can also be in a separate bead 12 can be accommodated. With ceiling panels 9 with continuous Perforation will be a tissue-like tape to insert a passage avoid pasty glue through the perforation of the ceiling tile.

Bei geschlossenen Deckenplatten 9 kann auch ein pastöser Kleber verwendet werden, wobei dann in der Sicke 12 mindestens zwei Bohrungen 13 vorhanden sind. In eine dieser Bohrungen 13 wird das pastöse Klebematerial 11' eingepreßt. Die andere Bohrung 13 dient zum Austritt des Klebematerials 11' bzw. zur Kontrolle, ob die Sicke 12 gefüllt ist.With closed ceiling panels 9, a pasty adhesive can also be used be, with at least two holes 13 then being provided in the bead 12 are. The pasty adhesive material 11 'is pressed into one of these bores 13. The other bore 13 serves for the exit of the adhesive material 11 'or for the control, whether the bead 12 is filled.

Eine weitere Befestigungsmöglichkeit zeigt Figur 4. Hierbei werden aus der Blechplatte 1, welche mit der Deckenplatte 9 verbunden werden soll, Laschen 14 durch dreiseitiges Freistanzen erzeugt. An jeder Lasche 14 wird an der zur Deckenplatte 9 gerichteten Seite ein doppelseitig klebendes Band 15 aufgebracht. Da in der Regel die Kühlelemente erst auf der Baustelle mit den Deckenplatten verbunden werden, wird erst hier die Schutzfolie von der Unterseite des Bandes 15 abgezogen und die Lasche 14 auf die Deckenplatte 9 gedrückt. Dadurch wird mit der Klebung sogar eine Zugspannung durch die Lasche 14, welche in ihre Ursprungslage zurückfedern will, erzeugt und die Anpressung verbessert.Another mounting option is shown in Figure 4. Here, the sheet metal plate 1, which is to be connected to the ceiling plate 9, tabs 14 through three-sided free cutting generated. On each tab 14 on the ceiling plate 9 facing side applied a double-sided adhesive tape 15. Because in the As a rule, the cooling elements are only connected to the ceiling panels at the construction site the protective film is only removed from the underside of the band 15 here and the tab 14 pressed onto the ceiling plate 9. This will help with the Gluing even a tensile stress through the tab 14, which is in its original position wants to spring back, generates and improves the contact pressure.

Eine solche Zugspannung läßt sich ebenfalls mit der in Figur 5 gezeigten Ausführungsart erzeugen. Hier wird die Verbindung der Deckenplatte 9 mit der Blechplatte 1 vorgenommen, indem in einer Aussparung 16 der Blechplatte 1 ein Verbindungselement, bestehend aus einem runden Federstahlteller 17 mit Klebeschicht 18, eingebracht wird. Hier wird durch die federnden Randbereiche ein Anpressen der Blechplatte 1 und somit des Kühlelements auf die Deckenplatte 9 erzielt.Such tension can also be done with the embodiment shown in Figure 5 produce. Here is the connection of the ceiling plate 9 with the sheet metal plate 1 made by a connecting element in a recess 16 of the sheet metal plate 1, consisting of a round spring steel plate 17 with adhesive layer 18, is introduced. Here is due to the resilient edge areas Pressing the sheet metal plate 1 and thus the cooling element onto the ceiling plate 9 achieved.

Werden sehr dünne (< 0,2 mm) doppelseitige Klebefolien zur Verbindung der Blechplatte 1 mit der Deckenplatte 9 verwendet, so können diese ohne nennenswerte Verschlechterung des Wärmeübergangs auch zwischen der Blechplatte 1 und der Deckenplatte 9 vollfächig oder streifenförmig eingesetzt werden.Are very thin (<0.2 mm) double-sided adhesive films for connecting the Sheet metal plate 1 used with the ceiling plate 9, so this can be without any noteworthy The heat transfer also deteriorates between the sheet metal plate 1 and the ceiling plate 9 can be used in full or in strips.

In Figur 6 ist eine Ausführungsart dargestellt, bei der auf eine Klebeverbindung verzichtet und eine rein mechanische Verbindung gewählt wird. Dazu wird die Blechplatte 1 im Randbereich mit einer doppelten Umkantung 19 versehen, deren horizontaler Abschluß unter eine Umkantung 20 der Deckenplatte 9 greift. Durch eine elastische Zwischenlage 21 werden Fertigungstoleranzen ausgeglichen und gleichzeitig ein Anpressen des Kühlelements auf die Deckenplatte 9 erzielt.FIG. 6 shows an embodiment in which an adhesive connection is used waived and a purely mechanical connection is selected. For this, the Sheet metal plate 1 provided in the edge region with a double edging 19, the horizontal end engages under an edge 20 of the ceiling plate 9. By an elastic intermediate layer 21, manufacturing tolerances are compensated for and achieved at the same time pressing the cooling element onto the ceiling plate 9.

In Figur 7 wird durch einen zweiteiligen Justierbügel 22 bzw. 22', welcher über Nuten in die oberen horizontalen Umkantungen der Deckenplatte 9 greift, einem Durchhang der Deckenplatte 9 entgegengewirkt. Die Kraft ist dabei durch den teleskopartig auseinanderschiebbaren Justierbügel 22 bzw. 22' einstellbar, wobei Bohrungen 23 zur Aufnahme eines Stifts zwecks Arretierung dienen. Zusätzlich kann durch Federn 24 ein Anpressen und somit ein guter wärmetechnischer Kontakt zwischen dem Kühlelement und der Deckenplatte 9 erzielt werden.In Figure 7 by a two-part adjustment bracket 22 or 22 ', which over Grooves in the upper horizontal folds of the ceiling plate 9, one Sag of the ceiling plate 9 counteracted. The power is through the Telescopic telescopic adjustment bracket 22 or 22 'adjustable, wherein Bores 23 are used to hold a pin for locking purposes. additionally can be pressed by springs 24 and thus a good thermal Contact between the cooling element and the ceiling plate 9 can be achieved.
