The invention relates to a cooled ceiling for cooling room air with heat-conducting rails, which are suspended on a bare ceiling and flowed through by cooling water, and ceiling elements which bear against the underside of the heat-conducting rails on a connection flange and are held thereon with clamping elements. In order to improve a cooled ceiling in such a manner that, even without observing extreme manufacturing tolerances, simple fastening of the ceiling elements on the heat-conducting rail and good heat transmission between ceiling elements and heat-conducting rails are guaranteed, the connection flange is to have a recess for a clamping element which can be inserted into it and is connected to the ceiling element. <IMAGE>

Description

Die Erfindung betrifft eine Kühldecke für Raumluftkühlung mit an einer Rohdecke abgehängten, von Kühlwasser durchströmten Wärmeleitschienen und unterseitig an den Wärmeleitschienen an einem Anschlußflansch anliegenden und daran mit Klemmelementen gehaltenen Deckenelementen.The invention relates to a cooling ceiling for room air cooling with suspended from a raw ceiling, through which cooling water flows, and on the underside of the heat conducting rails on a connecting flange and ceiling elements held thereon with clamping elements.

Derartige Kühldecken werden in thermisch hochbelasteten Räumen und bei hohen Komfortanforderungen eingesetzt. Sie führen Wärme durch Absorption der Strahlung von Wäremquellen oder von erwärmten Raumflächen und durch freie Konvektion über die erwärmte Raumluft ab.Such cooling ceilings are used in rooms subject to high thermal loads and with high comfort requirements. They dissipate heat by absorbing the radiation from heat sources or from heated room surfaces and by free convection via the heated room air.

Bei einer bekannten Kühldecke der eingangs beschriebenen Gattung (DE-GM 91 02 260) können die Deckenelemente unter anderem ausgerüstet sein mit Klemmzungen, die Rastelemente aufweisen, wobei die Klemmzungen über die ebenfalls mit Rastelementen versehenenen Außenseiten des Anschlußflansches geschoben werden. Das hat sich an sich bewährt, erfordert aber die Einhaltung genauer Fertigungstoleranzen.In a known cooling ceiling of the type described in the introduction (DE-GM 91 02 260), the ceiling elements can be equipped, inter alia, with clamping tongues which have latching elements, the clamping tongues being pushed over the outer sides of the connecting flange which are likewise provided with latching elements. This has proven itself in itself, but requires compliance with precise manufacturing tolerances.

Aufgabe der Erfindung ist es, eine Kühldecke der eingangs beschriebenen Art so zu verbessern, daß auch ohne Einhaltung extremer Fertigungstoleranzen eine einfache Befestigung der Deckenelemente an der Wärmeleitschiene sowie ein guter Wärmeübergang zwischen Deckenelementen und Wärmeleitschienen gewährleistet sind.The object of the invention is a cooling ceiling of the beginning to improve the type described so that even without adhering to extreme manufacturing tolerances, simple attachment of the ceiling elements to the heat conducting rail and good heat transfer between ceiling elements and heat conducting rails are ensured.

Diese Aufgabe wird dadurch gelöst, daß der Anschlußflansch eine Ausnehmung für ein darin einführbares,mit dem Deckenelement verbundenes Klemmelement aufweist. Nach bevorzugter Ausführung der Erfindung können in der Ausnehmung ein oder mehrere Klipse mit federnden Schenkeln angeordnet sein, wobei das Klemmelement zwischen die federnden Schenkel einführbar ist. Das ermöglicht eine einfache Montage und stellt auch den gewünschten Wärmeübergang zwischen dem Anschlußflansch der Wärmeleitschiene und dem daran anliegenden Deckenelement sicher.This object is achieved in that the connecting flange has a recess for a clamping element which can be inserted therein and is connected to the ceiling element. According to a preferred embodiment of the invention, one or more clips with resilient legs can be arranged in the recess, the clamping element being insertable between the resilient legs. This enables simple installation and also ensures the desired heat transfer between the connecting flange of the heat conducting rail and the ceiling element lying against it.

Besonders vorteilhaft ist eine Ausführung, bei der das Klemmelement einen verbreiterten Kopf besitzt und die Schenkel diesen Kopf hinterfassende Wölbungen aufweisen. Dann kann nämlich das Deckenelement mit dem verbreiterten Kopf seines Klemmelementes unter leichtem Druck montiert werden, wobei der verbreiterte Kopf zwischen die federnden Schenkel des oder der Klipse eingedrückt wird, wobei die den Kopf hinterfassenden Wölbungen die Einführbewegung des Kopfes unterstützen, bis das Deckenelement am Anschlußflansch anliegt. Der Kopf des Klemmelemetes kann außenseitige Einführungsschrägen aufweisen.A particularly advantageous embodiment is one in which the clamping element has a widened head and the legs have curvatures behind this head. Then the ceiling element can be mounted with the widened head of its clamping element under slight pressure, the widened head being pressed between the resilient legs of the clip or clips, the bulges behind the head supporting the insertion movement of the head until the ceiling element bears against the connecting flange . The head of the clamping element can have outside bevels.

Der oder die Klipse werden zweckmäßigerweise in zur Wärmeleitschiene parallelen inneren Nuten der Ausnehmung abgestützt. Bei einer praktischen Ausführung ist das Klemmelement mit einem Fuß auf das Deckenelement aufgeklebt.The clip or clips are expediently supported in inner grooves of the recess parallel to the heat conducting rail. In a practical version, the clamping element is glued to the ceiling element with one foot.

Eine Kühldecke besteht in der Regel aus mehreren Deckenelementen, die an zugeordneten Wärmeleitschienen gehalten sind. Die Wärmeleitschienen sind ihrerseits an einem von der Rohdecke abgehängten Träger befestigt. Um eine gleichmäßige Ausrichtung der Deckenelemente zu ermöglichen, geht ein weiterer Vorschlag der Erfindung dahin, die Wärmeleitschiene mit einer Schraubverbindung an einen Befestigungssteg eines Trägers anzuschließen, wobei die Schraube sich durch ein überdimmensioniertes Loch im Befestigungssteg erstreckt und der Befestigungssteg mittels der Schraube beidseits zwischen Einstellelementen aus Kugelpfanne und Kugelscheibe eingespannt ist. Damit besteht die Möglichkeit, die Wärmeleitschiene so im Raum zu orientieren, daß ihr zugeordnetes Deckenelement mit benachbarten Deckenelementen fluchtet. Zum Anschluß der Schraube kann die Wärmeleitschiene außenseitig eine Nut für den Schraubenkopf aufweisen. Bei einer bevorzugten Ausführung der Erfindung ist die Nut seitlich an der Wärmeleitschiene angeordnet.A chilled ceiling usually consists of several ceiling elements that are held on assigned heat conducting rails. The heat conducting rails are in turn attached to a support suspended from the bare ceiling. In order to enable a uniform alignment of the ceiling elements, a further proposal of the invention is to connect the heat conducting rail to a fastening web of a support with a screw connection, the screw extending through an oversized hole in the fastening web and the fastening web using the screw on both sides between adjusting elements Ball socket and ball washer is clamped. This makes it possible to orient the heat-conducting rail in the room in such a way that its assigned ceiling element is aligned with adjacent ceiling elements. To connect the screw, the heat conducting rail can have a groove for the screw head on the outside. In a preferred embodiment of the invention, the groove is arranged on the side of the heat conducting rail.

Im folgenden wird ein in der Zeichnung dargestelltes Ausführungsbeispiel der Erfindung erläutert; die einzige Figur zeigt schematisch und teilweise einen Schnitt durch eine Kühldecke.In the following an embodiment of the invention shown in the drawing is explained; the single figure shows schematically and partially a section through a cooling ceiling.

Unterhalb einer nicht dargestellten Rohdecke eines Raumes sind mehrere Träger 2 verlegt, von denen nur einer dargestellt ist. Der Träger 2 ist von Bügelschenkeln eines am Träger 2 befestigten Bügels 6 überfaßt. Am U-Steg des Bügels 6 ist mit einer Schraubverbindung 30 ein Tragwinkel 31 befestigt, an dessen freien Schenkel 32 mittels einer Schraube 10 eine Wärmeleitschiene 13 befestigt ist. Die Wärmeleitschiene 13 weist einen mit einem Kupferrohr 15 ausgekleideten Kühlwasserkanal 16 auf, der in nicht dargestellter Weise an den Wasserkreislauf eines Wasserkühlsystems angeschlossen ist.Several beams 2, of which only one is shown, are laid below a raw ceiling, not shown, of a room. The carrier 2 is covered by bracket legs of a bracket 6 attached to the bracket 2. On the U-web of the bracket 6, a support bracket 31 is fastened with a screw connection 30, on its free leg 32 by means of a Screw 10 is attached to a thermal conductor rail 13. The heat conducting rail 13 has a cooling water channel 16 lined with a copper tube 15, which is connected to the water circuit of a water cooling system in a manner not shown.

Unterseitig weist die Wärmeleitschiene 13 einen Anschlußflansch 17 auf, der sich beidseits der Wärmeleitschiene 13 erstreckt. Dieser Anschlußflansch 17 dient als Widerlager und zur Befestigung eines Deckenelementes 18 sowie auch zur Wärmeübertragung vom Deckenelement 18 zur Wärmeleitschiene 13.On the underside, the heat-conducting rail 13 has a connecting flange 17 which extends on both sides of the heat-conducting rail 13. This connecting flange 17 serves as an abutment and for fastening a ceiling element 18 and also for heat transfer from the ceiling element 18 to the heat conducting rail 13.

Das Deckenelement 18 besteht bei der dargestellten Ausführung aus einem Material mit guter Wärmeleitfähigkeit, z. B. Aluminium. Es erstreckt sich längs der Wärmeleitschiene 13 und besitzt eine Breite von ca. 200 mm. Etwa auf halber Breite ist das Deckenelement 18 lösbar am Anschlußflansch 17 befestigt.The ceiling element 18 in the embodiment shown consists of a material with good thermal conductivity, e.g. B. aluminum. It extends along the heat conducting rail 13 and has a width of approximately 200 mm. About half the width of the ceiling element 18 is releasably attached to the connecting flange 17.

Dazu weist der Anschlußflansch 17 unterhalb der Wärmeleitschiene 13 eine Ausnehmung 33 auf, die sich bei der dargestellten Ausführung längs der Wärmeleitschiene 13 erstreckt. Die Ausnehmung 33 weist innere Nuten 34 auf, an denen ein oder mehrere Klipse 35 mit federnden Schenkeln 36, 37 abgestützt sind.For this purpose, the connecting flange 17 has a recess 33 below the heat conducting rail 13, which extends along the heat conducting rail 13 in the embodiment shown. The recess 33 has inner grooves 34, on which one or more clips 35 are supported with resilient legs 36, 37.

Zwischen die beiden federnden Schenkel 36, 37 ist der verbreiterte Kopf 38 eines Klemmelementes 39 einführbar, welches mit seinem Fuß 40 auf das Deckenelement 18 aufgeklebt ist. Der Kopf 38 weist außenseitige Einführungsschrägen auf. Die federnden Schenkel 36 besitzen den eingeführten Kopf 38 hinterfassende Wölbungen 42, die die Einführbewegung des Kopfes 38 unterstütezn, so daß das Deckenelement 18 gegen den Anschlußflansch 17 gezogen wird. Das Deckenelement 18 kann aber auch leicht wieder von der Wärmeleitschiene 13 gelöst werden.The widened head 38 of a clamping element 39 can be inserted between the two resilient legs 36, 37 and is glued to the ceiling element 18 with its foot 40. The head 38 has outside bevels. The resilient legs 36 have the inserted Head 38 behind bulges 42, which support the insertion movement of the head 38, so that the ceiling element 18 is pulled against the connecting flange 17. The ceiling element 18 can also be easily detached from the heat conducting rail 13.

Zum Ausrichten des Deckenelementes 18 gegenüber benachbarten Deckenelementen kann die Orientierung der Wärmeleitschiene 13 im Raum verändert werden. Das erfolgt mit Hilfe der Schraube 10, deren Profilkopf 11 in einer seitlich an der Wärmeschiene 13 angeordneten, hinterschnittenen Nut 12 gehalten ist. Die Schraube 10 erstreckt sich durch ein überdimmensioniertes Loch 43 im Schenkel 32 des Tragwinkels 31. Beidseits des Schenkels 32 und die Schraube 10 überfassend sind Einstellelemente vorgesehen, die jeweils aus einer Kugelpfanne 44 und einer damit zusammenwirkenden Kugelscheibe 45 bestehen. Nach Ausrichtung des Deckenelementes 18 mit der zugeordneten Wärmeschiene 13 wird der Schenkel 32 des Tragwinkels 31 zwischen diesen Einstellelementen durch Aufdrehen einer Mutter 46 auf die Schraube 10 eingespannt.To align the ceiling element 18 with adjacent ceiling elements, the orientation of the heat conducting rail 13 in the room can be changed. This takes place with the aid of the screw 10, the profile head 11 of which is held in an undercut groove 12 arranged laterally on the heat rail 13. The screw 10 extends through an oversized hole 43 in the leg 32 of the support bracket 31. On both sides of the leg 32 and the screw 10 comprehensive adjustment elements are provided, each consisting of a ball socket 44 and a cooperating spherical washer 45. After aligning the ceiling element 18 with the associated heat rail 13, the leg 32 of the support bracket 31 is clamped between these adjustment elements by screwing a nut 46 onto the screw 10.
