Description

Die vorliegende Erfindung betrifft ein Plattenelement zum modularen Aufbau von Gehäusen, vorzugsweise von Lüftungs- und Klimaanlagen, mit zwei beabstandeten und im Wesentlichen parallel zueinander verlaufenden Seitenwänden mit dazwischen angeordneter Isolierung und mit einer im rechten Winkel zu den Seitenwänden um das Plattenelement verlaufenden Stirnfläche, wobei die Stirnfläche in der Querschnittansicht zwei voneinander beabstandete Metallprofile aufweist, zwischen denen Isoliermaterial angeordnet ist. Ein solches plattenelement ist aus jeder einzelnen der Druckschriften DE-A-3 244 743 , US-A 1 697 189 und FR-A-2 604 739 bekannt.The present invention relates to a plate member for modular construction of housings, preferably of ventilation and air conditioning systems, with two spaced and substantially parallel side walls with interposed insulation and with a perpendicular to the side walls extending around the plate member end face, said End face in the cross-sectional view has two spaced apart metal profiles, between which insulating material is arranged. Such a plate element is from each of the publications DE-A-3 244 743 . US-A 1 697 189 and FR-A-2 604 739 known.

Der modulare Aufbau mit Plattenelementen im Lüftungs- und Klimaanlagenbau ist bereits bekannt. Der Stand der Technik offenbart zahlreiche Varianten zur Realisierung derartiger Plattenelemente. Die DE 30 42 109 offenbart ein Plattenelement mit einem Isolierstoffkern, an dessen Stirnflächen jeweils ein Stirnprofil von U-förmigem Querschnitt angeordnet ist. Nachteilig bei diesen Plattenelementen ist der hohe Wärmeübergang in Bereich der Stirnprofile.The modular design with panel elements in ventilation and air conditioning systems is already known. The prior art discloses numerous variants for the realization of such plate elements. The DE 30 42 109 discloses a plate member having an insulating core, on whose end faces in each case an end profile of U-shaped cross-section is arranged. A disadvantage of these plate elements is the high heat transfer in the region of the end profiles.

Die FR 2 604 739 beschreibt ein Fassadenpaneel mit zwei parallel verlaufenden Metallplatten, zwischen denen ein Isolierkern aus Mineralwolle angeordnet ist. Zur Verbindung der Plattenelemente an deren Stirnseite sind Verankerungselemertt,8' aus einem Elastomer vorgesehen, sodass ein Spalt zwischen den einzelnen Fassadenpaneelen verbleibt.The FR 2 604 739 describes a facade panel with two parallel metal plates, between which an insulating core of mineral wool is arranged. To connect the plate elements on the front side Verankerungselemertt, 8 'are provided of an elastomer, so that a gap between the individual facade panels remains.

Die US 1,697,189 zeigt ein isolierendes Plattenelement mit zwei zueinander parallel verlaufenden Seitenwänden, zwischen denen Isoliermaterial angeordnet ist.The US 1,697,189 shows an insulating plate member having two mutually parallel side walls, between which insulating material is arranged.

Die DE 32 44 743 A1 offenbart eine Rollwand für Kühl- und Isolierbehälter, wobei keinerlei Wärmebrücken von der Innen- zur Außenseite der Rollwand bestehen.The DE 32 44 743 A1 discloses a rolling wall for cooling and insulating containers, with no thermal bridges from the inside to the outside of the roll wall.

Aufgabe der vorliegenden Erfindung ist es daher, ein Plattenelement zu schaffen, weiches obigen Nachteil nicht aufweist und die an den Außenbereich abgegebene Wärmemenge reduziert.It is therefore an object of the present invention to provide a plate member which does not have the above disadvantage and reduces the amount of heat discharged to the outside.

Dies wird erfindungsgemäß dadurch erreicht, dass das Isoliermaterial von Buchsen durchsetzt ist, die zur Verbindung mit benachbarten Plattenelementen und/oder zur Verbindung mit Eckprofilen vorgesehen sind.This is inventively achieved in that the insulating material is penetrated by sockets, which are provided for connection to adjacent plate elements and / or for connection to corner profiles.

Um den steigenden Anforderungen an Klimageräten gerecht zu werden, müssen technische Parameter wie Wärmedurchgangskoeffizient oder Wärmebrückenfaktor des Klimagehäuses entsprechende Werte aufweisen. Die Norm EN 1886 unter Punkt 7 beschreibt eine Einteilung von RLT (Raumluft-technischen) Geräten in Klassen, wobei die Geräte in den Klassen T1 bzw. T2 im Wesentlichen vollständig von der warmen zur kalten Seite hin thermisch entkoppelt sind. Durch die erfindungsgemäße Stirnfläche können diese Normwerte mit einfacher Konstruktion ermöglicht werden. Durch die beabstandeten Metallprofile kann eine günstige thermische Entkopplung realisiert werden.In order to meet the increasing demands on air conditioners, technical parameters such as heat transfer coefficient or thermal bridge factor of the air conditioning housing must have corresponding values. The standard EN 1886 under point 7 describes a classification of RLT (room air-technical) devices in classes, the devices in the classes T1 and T2 are substantially completely thermally decoupled from the warm to the cold side. Due to the end face according to the invention, these standard values can be made possible with a simple construction. Due to the spaced metal profiles, a favorable thermal decoupling can be realized.

Eine bevorzugte Ausführungsform der Erfindung sieht vor, dass das Isoliermaterial im Wesentlichen quaderförmig ausgebildet ist und dass die Metallprofile das Isoliermaterial an dessen Schmalseite umgreifen. Damit wird ein möglichst großer Abstand zwischen den Metallprofilen ermöglicht, wodurch der Wärmeübergang zusätzlich reduziert wird. Durch das Umgreifen der Metallprofile an der Schmalseite wird zudem weniger Material benötigt, um die naturgemäß gut wärmeleitenden Metallflächen zu minimieren.A preferred embodiment of the invention provides that the insulating material is formed substantially cuboid and that the metal profiles embrace the insulating material on its narrow side. This allows the greatest possible distance between the metal profiles, whereby the heat transfer is additionally reduced. By the Enveloping the metal profiles on the narrow side also requires less material to minimize the naturally good heat-conducting metal surfaces.

Eine spezielle Ausführungsform der Erfindung sieht vor, dass die Metallprofile den Rand des Isoliermaterials mit einem im Wesentlichen U-förmigen Rand umgreifen. Durch diese Gestaltungsform wird ein guter Halt des Isoliermaterials gewährleistet, welches selbst bei großen thermischen Schwankungen fix zwischen den Metallprofilen verankert bleibt. Vorteilhaft ist vorgesehen, dass die Metallprofile zumindest teilweise doppelwandig ausgeführt sind, wodurch eine zusätzliche Stabilität des Profilstirnrahmens erzielt wird.A special embodiment of the invention provides that the metal profiles surround the edge of the insulating material with a substantially U-shaped edge. This design ensures a good hold of the insulating material, which remains firmly anchored between the metal profiles even with large thermal fluctuations. It is advantageously provided that the metal profiles are at least partially double-walled, whereby additional stability of the profile end frame is achieved.

Vorteilhaft ist weiters vorgesehen, dass die Metallprofile parallel zueinander verlaufende Abschnitte aufweisen, zwischen denen ein isolierender Spalt verbleibt. Durch die parallel verlaufenden Abschnitte wird eine höhere Festigkeit und eine bessere Verwindungssteifigkeit des Profilstirnrahmens erzielt, der eingeschlossene Luftspalt wirkt als Isolatorschicht und verbessert dadurch die thermische Entkopplung.Advantageously, it is further provided that the metal profiles have mutually parallel sections between which an insulating gap remains. By the parallel sections, a higher strength and a better torsional rigidity of the profile end frame is achieved, the trapped air gap acts as an insulator layer, thereby improving the thermal decoupling.

Günstigerweise ist vorgesehen, dass die Metallprofile zur Aufnahme einer Dichtung Rinnen aufweisen. Vorzugsweise können doppelt umlaufende Dichtungen in die vorgesehenen Rinnen eingelegt werden, die dem RLT-Gehäuse den erforderlichen Dichtheitsgrad im Unterwie im Überdruckbereich verleihen. Vorteilhaft ist vorgesehen, dass die Dichtung eine EPDM-Dichtung ist. Diese Kautschuk-Dichtung zeichnet sich u.a. durch Schwerentflammbarkeit aus und widersteht weitgehend auch großen Temperaturschwankungen.It is advantageously provided that the metal profiles have grooves for receiving a seal. Preferably, double-circumferential seals can be inserted into the grooves provided, which give the RLT housing the required degree of tightness in Unterwie in the overpressure. It is advantageously provided that the seal is an EPDM seal. This rubber seal is characterized i.a. by flame retardancy and largely withstands large temperature fluctuations.

Besonders günstig ist es, wenn die Metallprofile mit jeweils einer Seitenwand verbunden sind. Durch diese Maßnahme wird eine erhöhte Festigkeit des Plattenelementes erreicht. Da die Metallprofile bevorzugt vom U-förmigen Rand bis zu den ebenen Flächen einstückig ausgebildet sind, können diese auf einfache Art mit den Seitenwänden verbunden werden, wobei eine stabile doppelwandige Konstruktion erzielt wird. Zum Verbinden der Metallprofile mit den Seitenwänden werden übliche mechanische Befestigungsmittel, vorzugsweise Einnietmuttern, vorgesehen. Selbstverständlich können auch andere Methoden, wie z.B. Punktschweißen, angewendet werden. Vorteilhaft ist vorgesehen, dass die Seitenwände mit den Metallprofilen zumindest teilweise verrollt werden, wodurch eine zusätzliche Festigkeit der Konstruktion ermöglicht wird. Durch das Verrotten kann auch ein vertikales Verrutschen der Seitenwand in Bezug auf die Metallprofile verhindert werden.It is particularly favorable if the metal profiles are each connected to one side wall. By this measure, an increased strength of the plate element is achieved. Since the metal profiles are preferably integrally formed from the U-shaped edge to the flat surfaces, these can be easily connected to the side walls, with a stable double-walled construction is achieved. For connecting the metal profiles to the side walls, conventional mechanical fastening means, preferably rivet nuts, are provided. Of course, other methods, such as spot welding, can be used. It is advantageously provided that the side walls are at least partially rolled with the metal profiles, whereby an additional strength of the construction is made possible. By rotting, a vertical slippage of the side wall with respect to the metal profiles can be prevented.

Eine bevorzugte Ausführungsform der Erfindung sieht vor, dass das Isoliermaterial hitze- und feuerhemmendes Material, vorzugsweise PU-Harz, ist. Polyurethanharz-Produkte zeichnen sich u.a. durch gute Feuerbeständigkeit, gute phonische Absorption und gute Widerstandsfähigkeit gegen Rissebildung aus. Vorteilhaft ist vorgesehen, dass die Buchsen, die zum Verbinden des Plattenelementes mit anderen Plattenelementen im modularen Verbund vorgesehen sind, beispielsweise als Eingießmuttern mit üblichem metrischem Gewinde ausgeführt sind die für die Aufnahme von korrespondierenden metrischen Schrauben vorgesehen sind.A preferred embodiment of the invention provides that the insulating material is heat and fire retardant material, preferably PU resin. Polyurethane resin products are characterized i.a. good fire resistance, good phonic absorption and good resistance to cracking. It is advantageously provided that the sockets, which are provided for connecting the plate element with other plate elements in a modular composite, for example, are designed as Eingießmuttern with usual metric thread which are provided for receiving corresponding metric screws.

Schließlich ist vorgesehen, dass das Isoliermaterial zwischen den Seitenwänden feuerhemmendes und temperaturdämmendes Material, vorzugsweise Mineralwolle, ist. Die Isolierung mit Steinwolle bewirkt eine günstige Dämmung gegen Hitze, Kälte und Lärm. Darüber hinaus wird ein Standardprodukt verwendet, welches nicht brennbar, wasserabweisend und alterungsbeständig ist.Finally, it is provided that the insulating material between the side walls is fire-retardant and temperature-insulating material, preferably mineral wool. The insulation with rock wool causes a favorable insulation against heat, cold and noise. In addition, a standard product is used which is nonflammable, water repellent and resistant to aging.

Fig. 1 zeigt eine Querschnittansicht auf die Stirnseite eines Plattenelementes 1. Die Stirnseite weist zwei voneinander beabstandete Metallprofile 2, 2' auf, zwischen denen Isoliermaterial 3 angeordnet ist. Es besteht keine metallische Verbindung zwischen den Metallprofilen 2, 2', die zu einer unerwünschten thermischen Kopplung von einer Seitenwand 4 zur parallel gegenüberliegenden Seitenwand 4' führen würde. Die Metallprofile 2, 2' umgreifen das im Wesentlichen quaderförmige Isoliermaterial 3 an dessen Schmalseite, wobei die Metallprofile 2, 2' den Rand des Isoliermaterials 3 mit einem im Wesentlichen U-förmigen Rand umgreifen. Das Isoliermaterial 3 ist beispielsweise PU-Harz, welches bei der Herstellung in flüssiger Form zwischen die Metallprofile 2, 2' gegossen wird. Um ein Auslaufen des flüssigen Harzes zu verhindern, ist ein Keder 5 vorgesehen. Diese Kunststoffabdeckung wird nach dem Aushärten des Isoliermaterials 3 wieder entfernt. Fig. 1 shows a cross-sectional view of the end face of a plate member 1. The front side has two spaced-apart metal profiles 2, 2 ', between which insulating material 3 is arranged. There is no metallic connection between the Metal profiles 2, 2 ', which would lead to an undesirable thermal coupling of a side wall 4 to the parallel opposite side wall 4'. The metal profiles 2, 2 'embrace the essentially cuboidal insulating material 3 on its narrow side, the metal profiles 2, 2' embracing the edge of the insulating material 3 with a substantially U-shaped edge. The insulating material 3 is for example PU resin, which is poured in the manufacture in liquid form between the metal profiles 2, 2 '. To prevent leakage of the liquid resin, a piping 5 is provided. This plastic cover is removed after the curing of the insulating material 3 again.

Die Metallprofile 2, 2' sind zumindest teilweise doppelwandig ausgeführt, was zu einer verbesserten Stabilität führt. Neben diesen parallel zueinander verlaufenden Abschnitten schließen die Metallprofile 2, 2' einen isolierenden Spalt 6, 6' ein, der eine verbesserte thermische Entkopplung bewirkt. In weiterer Folge weisen die Metallprofile 2, 2' Rinnen 7, 7' auf, die zur Aufnahme von Dichtungen 8, 8' vorgesehen sind. Die Metallprofile 2, 2' sind mit jeweils einer Seitenwand 4, 4' verbunden. Durch diese Verbindung wird eine günstige Festigkeit des Plattenelementes 1 erzielt. Als Verbindungsmittel werden seitliche Einnietmuttern 9, 9' verwendet, die der Konstruktion den erforderlichen Halt verleihen. Eine weitere Festigkeitssteigerung wird durch das Verrotten der Seitenwände 4, 4' mit den Metallprofilen 2, 2' erreicht, wobei die Seitenwände 4, 4' zumindest teilweise in die Rinnen 7, 7' der Metallprofile 2, 2' eingreifen. Zum Verbinden des Plattenelementes 1 mit den Stirnflächen anderer Plattenelemente 1 sind Buchsen 10 vorgesehen, die das Isoliermaterial 3 durchsetzen. Diese Buchsen 10 werden beim Gussvorgang des Isoliermaterials 3 eingesetzt und dienen zur Aufnahme passender Schrauben, die beispielsweise von entsprechenden Eckprofilen 14 aus in die Stirnseite der Plattenelemente 1 eingeschraubt werden. Die in Fig. 1 eingezeichnete Buchse 10 ist nur beispielhaft für eine Vielzahl von durchsetzenden Buchsen 10 vorgesehen, die in regelmäßigen Abständen an der Stirnseite der Plattenelemente 1 angeordnet sind.The metal profiles 2, 2 'are at least partially double-walled, resulting in improved stability. In addition to these mutually parallel sections, the metal profiles 2, 2 'include an insulating gap 6, 6', which causes an improved thermal decoupling. Subsequently, the metal profiles 2, 2 'grooves 7, 7', which are provided for receiving seals 8, 8 '. The metal profiles 2, 2 'are each connected to a side wall 4, 4'. By this connection, a favorable strength of the plate element 1 is achieved. As connecting means lateral riveting nuts 9, 9 'are used, which give the construction the necessary support. A further increase in strength is achieved by the rotting of the side walls 4, 4 'with the metal profiles 2, 2', wherein the side walls 4, 4 'at least partially in the grooves 7, 7' of the metal profiles 2, 2 'engage. To connect the plate member 1 with the end faces of other plate members 1 sockets 10 are provided, which pass through the insulating material 3. These bushes 10 are used in the casting process of the insulating material 3 and serve to accommodate matching screws that are screwed, for example, from corresponding corner profiles 14 in the end face of the plate elements 1. In the Fig. 1 drawn socket 10 is provided only by way of example for a plurality of interspersing sockets 10, which are arranged at regular intervals on the front side of the plate elements 1.

Fig. 2 zeigt eine dreidimensionale Darstellung des in Fig. 1 gezeigten Abschnittes eines Plattenelementes 1. Die beabstandeten Metallprofile 2, 2' umschließen die Schmalseite des Isoliermaterials 3 mit einem im Wesentlichen U-förmigen Rand. Die Metallprofile 2, 2' weisen zumindest teilweise parallel zueinander verlaufende Abschnitte auf, zwischen denen ein isolierender Spalt 6, 6' verbleibt. Die Metallprofile weisen rinnenförmige Abschnitte 7, 7' auf, die zur Aufnahme von rundum verlaufenden Dichtungen 8, 8' vorgesehen sind. Als Isolierung 11 zwischen den Seitenwänden 4, 4' ist beispielsweise Steinwolle vorgesehen, die neben der Wärmedämmung gute feuer- und lärmhemmende Eigenschaften aufweist. Durch die doppelwandige rahmenlose Konstruktion mit den Seitenwänden 4, 4' in Kombination mit dem Profilstirnrahmen 2, 2' kann eine vorteilhafte Festigung der Konstruktion erreicht werden. Zusätzliche Stabilität erreicht man durch das Verrotten der Seitenwände 4, 4' mit den Metallprofilen 2,2'. Fig. 2 shows a three-dimensional representation of the in Fig. 1 The spaced metal profiles 2, 2 'enclose the narrow side of the insulating material 3 with a substantially U-shaped edge. The metal profiles 2, 2 'have at least partially mutually parallel sections, between which an insulating gap 6, 6' remains. The metal profiles have channel-shaped sections 7, 7 ', which are provided for receiving circumferentially extending seals 8, 8'. As insulation 11 between the side walls 4, 4 'rock wool is provided, for example, the next the insulation has good fire and noise-reducing properties. By the double-walled frameless construction with the side walls 4, 4 'in combination with the profile end frame 2, 2', an advantageous consolidation of the construction can be achieved. Additional stability is achieved by rotting the side walls 4, 4 'with the metal profiles 2,2'.

Fig. 3 zeigt ein RLT-Gehäuse mit Plattenelementen 1 verschiedener Standardgrößen. Im Inneren ist die Aufnahme von Lüftungs- und Klimaanlagen vorgesehen, die neben starker Wärmeentwicklung auch beträchtliche Lärmemissionen verursachen. Um eine entsprechende Isolierwirkung zu erreichen, sind die erfindungsgemäßen Plattenelemente 1 vorgesehen, welche sich durch eine rahmenlose Konstruktion für ein im Wesentlichen thermisch entkoppeltes System auszeichnen. Die einzelnen Plattenelemente 1 werden mit der Stirnseite miteinander verbunden. Die Plattenelemente 1 werden beispielsweise mit Längsholmen 12 und Querholmen 13 verschraubt, an den Ecken sind vertikale Eckprofile 14 vorgesehen, die ebenfalls ein thermisch entkoppeltes System wie die Plattenelemente 1 aufweisen. Das Gehäuse kann beispielsweise auf U-förmigen Profilschienen 15, 15' ruhen, welches durch schwingungsdämpfende Auflagen vibrationsgedämpft gelagert ist. Fig. 3 shows an RLT housing with plate elements 1 different standard sizes. Inside, the inclusion of ventilation and air conditioning systems is provided, which cause not only strong heat generation but also considerable noise emissions. In order to achieve a corresponding insulating effect, the plate elements 1 according to the invention are provided, which are characterized by a frameless construction for a substantially thermally decoupled system. The individual plate elements 1 are connected to each other with the front side. The plate elements 1 are screwed, for example, with longitudinal bars 12 and transverse bars 13, at the corners vertical corner profiles 14 are provided which also have a thermally decoupled system as the plate elements 1. The housing can rest, for example, on U-shaped profile rails 15, 15 ', which is mounted vibration-damped by vibration-damping pads.

Fig. 4 zeigt ein schematisch dargestelltes weiteres Ausführungsbeispiel eines RLT-Gehäuses. Die thermisch getrennten Plattenelemente 1 weisen hier eine standardisierte Einheitsgröße auf. Zum kantenseitigen Verbinden der Plattenelemente 1 ist ein Eckprofil 14 vorgesehen, welches einen im Wesentlichen C-förmigen Abschnitt 19 aus Metall, vorzugsweise aus Stahl, und eine dreieckige Eckleiste 17 aus Kunststoff, vorzugsweise aus Polypropylen, aufweist. Durch diese aus Kunststoff bestehende Eckleiste 17 kann kantseitig ebenfalls eine thermische Entkopplung realisiert werden. Die Konstruktion der Türen 16 ist ebenfalls von der Innen- zur Außenseite thermisch entkoppelt. Die Fig. 4a zeigt eine Vorderansicht des in Fig. 4 dargestellten Gehäuses. Die Fig. 4b zeigt eine Schnittdarstellung entlang der Achse A-A aus Fig. 4a mit einem Detail C, auf welches in der Fig.6 noch näher eingegangen wird. Fig. 4 shows a schematically illustrated another embodiment of an RLT housing. The thermally separated plate elements 1 here have a standardized unit size. For edge-side joining of the plate elements 1, a corner profile 14 is provided, which has a substantially C-shaped section 19 made of metal, preferably made of steel, and a triangular corner strip 17 made of plastic, preferably polypropylene. By this made of plastic corner strip 17 can also be realized on the edge side thermal decoupling. The construction of the doors 16 is also thermally decoupled from the inside to the outside. The Fig. 4a shows a front view of the in Fig. 4 illustrated housing. The Fig. 4b shows a sectional view along the axis AA Fig. 4a with a detail C, on which in the Figure 6 will be discussed in more detail.

Fig. 5 zeigt eine schematische Vorderansicht eines Eckprofils 14 mit dem C-förmigen Abschnitt 19 aus Metall sowie der dreieckigen Eckleiste 17 aus Kunststoff. Der C-förmige Abschnitt 19 ist an seinem mittleren Teil mit der Eckleiste 17 verbindbar, vorzugsweise mit der beispielhaft gezeigten Schraube 18 verschraubt. Fig. 5 shows a schematic front view of a corner profile 14 with the C-shaped portion 19 made of metal and the triangular corner molding 17 made of plastic. The C-shaped portion 19 is connectable at its central part with the corner strip 17, preferably screwed to the screw 18 shown by way of example.

Fig. 5a zeigt das Eckprofil 14 in einer perspektivischen Darstellung mit Eckleiste 17 und metallischem Teil 19, die mit Schrauben 18 verbunden werden. Fig. 5a shows the corner profile 14 in a perspective view with corner strip 17 and metallic part 19, which are connected by screws 18.

Fig. 6 zeigt das Detail C aus Fig. 4b in einer vergrößerten Darstellung. Zum kantseitigen Verbinden der Plattenelemente 1 ist das Eckprofil 14 vorgesehen, welches einen im Wesentlichen C-förmigen Abschnitt 19 aus Metall, vorzugsweise aus Stahl, und eine dreieckige, Eckleiste 17 aus Kunststoff aufweist. Eine Abdeckleiste 20 dient zum Abdecken des C-förmigen Abschnittes. Der C-förmige Abschnitt 19 ist an seinem mittleren Teil mit der Eckleiste 17 verbindbar, beispielsweise durch die Schrauben 18. Vorteilhaft ist, dass der C-förmige Abschnitt 19 des Eckprofils 14 von den innenliegenden Metallprofilen 2, 2' der Plattenelemente 1, vorzugsweise durch die Eckleiste 17, beabstandet ist. Dadurch wird sichergestellt, dass keine metallische und damit gut wärmeleitende Verbindung von innenliegendem Metallprofil 2 zum gegenüberliegenden Metallprofil 2' und damit zur außenliegenden Seitenwand 4' besteht. Zum kantseitigen Verbinden der Plattenelemente 1 mit dem Eckprofil 14 sind das Isoliermaterial 3 durchsetzende Buchsen 10, beispielsweise aus Messing, angeordnet, die zur Aufnahme von korrespondierenden Schrauben vorgesehen sind. Im Weiteren ist in dieser Figur beispielhaft eine Tür 16 dargestellt, die vom Gehäuseinnenraum 21 nach außen hin ebenfalls thermisch entkoppelt ist. Hierfür ist ein Kunststoffprofil 22 mit rechteckförmigem Querschnitt angeordnet. Dieses Kunststoffprofil 22 kann beispielsweise glasfaserverstärkt sein. Außerdem dient zur thermischen Entkopplung eine Türdichtung 24, vorzugsweise eine EPDM-Dichtung, die eine thermische Trennung vom Innenraum 21 des Gehäuses nach außen hin bewirkt. Fig. 6 shows detail C. Fig. 4b in an enlarged view. For edge-side joining of the plate elements 1, the corner profile 14 is provided, which has a substantially C-shaped portion 19 made of metal, preferably made of steel, and a triangular, corner strip 17 made of plastic. A cover strip 20 serves to cover the C-shaped section. The C-shaped portion 19 is connectable at its central part with the corner bar 17, for example by the screws 18. It is advantageous that the C-shaped portion 19 of the corner profile 14 of the inner metal profiles 2, 2 'of the plate elements 1, preferably through the corner bar 17, is spaced. This ensures that there is no metallic and therefore good heat-conducting connection of the inner metal profile 2 to the opposite metal profile 2 'and thus to the outer side wall 4'. For edge-side joining of the plate elements 1 with the corner profile 14, the insulating material 3 through bushings 10, for example, brass, arranged, which are provided for receiving corresponding screws. In addition, in this figure, a door 16 is exemplified, which is also thermally decoupled from the housing interior 21 to the outside. For this purpose, a plastic profile 22 is arranged with a rectangular cross-section. This plastic profile 22 may be glass fiber reinforced, for example. In addition, a door seal 24 is used for thermal decoupling, preferably an EPDM seal, which effects a thermal separation from the interior 21 of the housing to the outside.

Es versteht sich von selbst, dass die vorliegende Erfindung nicht auf die in den Figuren dargestellten Ausführungsbeispiele beschränkt ist, noch durch diese eingeschränkt werden soll. Als Isolierung und als Isoliermaterial können selbstverständlich auch andere Materialien als Mineralwolle und PU-Harz eingesetzt werden. Auch die Eckleiste aus Kunststoff kann neben der in den Figuren dargestellten dreieckigen Form eine andere Geometrie, beispielsweise eine polygonale, aufweisen.It goes without saying that the present invention is not limited to the exemplary embodiments shown in the figures, nor should they be limited by them. Of course, other materials than mineral wool and PU resin can be used as insulation and as insulating material. Also, the plastic corner strip, in addition to the triangular shape shown in the figures, another geometry, such as a polygonal have.
