Damit soll erreicht werden, dass ein in dem Kältekreislauf geführtes brennbares Kühlmittel, beispielsweise ein Gemisch aus Propan und ISO-Propan, im Leckagefall nicht in den Schaltschrankinnenraum gelangen kann. Eine Entzündung des gasförmigen Kühlmittels soll somit verhindert werden. Somit geht es bei dieser konstruktiven Ausgestaltung eines Kühlgerätes in Verbindung mit einem Schaltschrank darum, das mit einem gasförmigen Kühlmittel betriebene Kühlgerät so auszubilden, dass eine Entzündung des gasförmigen Kühlmittels verhindert wird.In order to is to be achieved that a run in the refrigeration cycle flammable Coolant, For example, a mixture of propane and ISO-propane, in case of leakage not in the Cabinet interior can get. An ignition of the gaseous coolant should thus be prevented. Thus it is with this constructive Design of a cooling device in connection with a control cabinet around it, that with a gaseous coolant operated cooling device in such a way that inflammation of the gaseous refrigerant is prevented.

Aus dem vorliegenden Stand der Technik geht folglich hervor, dass zur Kühlung von in explosionsgefährdeten Räumen angeordneten elektri schen Geräten oder Schaltschränken mit Schaltschrankwänden ein konventionelles nicht explosionsgeschütztes Kühlgerät mit Verflüssiger, Verdampfer und Kompressor, d. h. ein Klimagerät, welches an dem Schaltschrank angeflanscht ist, nicht vorgesehen ist.Out The present state of the art therefore shows that the cooling from in potentially explosive clear arranged electrical rule devices or control cabinets with control cabinet walls a conventional non-explosion-proof cooling unit with condenser, evaporator and compressor, d. H. an air conditioner, which is flanged to the cabinet, not provided is.
Demgegenüber ist es Aufgabe der vorliegenden Erfindung eine Kühlanordnung für einen Schaltschrank mit einem Kühlgerät zum Einsatz in explosionsgefährdeten Räu men zur Verfügung zu stellen, das in Verbindung mit einem Schaltschrank oder einem sonstigen, elektronische Einbauten aufnehmenden Gehäuse für den explosionsgefährdeten Bereich ein CE-conformes komplettes Betriebsmittel für den Einsatz in explosionsgefährdeten Bereichen geeignet ist, wobei so wenig explosionsgeschützte Komponente wie möglich gebraucht werden sollen.In contrast, it is an object of the present invention to provide a cooling arrangement for a control cabinet with a cooling device for use in hazardous Räu men available that record in conjunction with a cabinet or other, electronic fixtures the housing for the hazardous area is a CE-compliant complete equipment suitable for use in potentially explosive atmospheres, with as little explosion-proof component as possible to be used.
Gelöst wird diese Aufgabe mit einem Schaltschrank mit einer Schaltschrankwand und mit mindestens einem Kühlgerät mit den im Anspruch 1 angegebenen Merkmalen und mit einem Kühlgerät für in explosionsgefährdeten Räumen aufgestellte Schaltschränke mit den im Anspruch 3 angegebenen Merkmalen.Is solved this task with a control cabinet with a cabinet wall and with at least one cooling device with the characterized in claim 1 features and with a cooling device for in hazardous clear installed control cabinets with the features specified in claim 3.
Danach besteht die Erfindung zur Schaffung einer gas- und staubdichten Baueinheit darin, dass an die Schaltschrankwand ein dichtgeschweißtes, ex-zulassungsfreie Bauelemente des Kühlgerätes aufnehmendes erstes Gehäuse mit in der Gehäusewand vorgesehenen, mit einer Rückschlagklappe versehene Warmlufteintrittsöffnung und einer Kaltluftaustrittsöffnung vermittels eines umlaufenden Flansches für eine umlaufende Dichtung zur Schaltschrankwand angeflanscht ist, wobei auf das erste Gehäuse ein zweites Gehäuse zur Aufnahme von ex-zulassungserforderlichen Bauelementen aufgesattelt ist, das den Verflüssigerlüfter mit explosionsgeschütztem Motor für den Umgebungslufteintritt und den Verflüssiger des Kühlgerätes aufnimmt, und dass in dem Innenraum des ersten Gehäuses Verbindungsrohre, z. B. Edelstahlrohre, gasdicht mit dem Gehäuse verbunden sind, an die die kälteseitigen Verbindungsleitungen angelötet sind, die zum externen Verflüssiger mit dem zweiten Gehäuse führen, dessen Gehäusewand mit einer Umgebungsluftaustrittsöffnung versehen ist.After that the invention is to provide a gas and dustproof Assembly in that on the cabinet wall a tightly welded, ex-approval-free Components of the cooling device receiving first housing with in the housing wall provided with a non-return valve Warm air inlet opening and a cold air outlet opening by means of a circumferential flange for a circumferential seal flanged to the control cabinet wall, wherein the first housing a second housing saddled up to accommodate ex-approval required components is that with the condenser fan explosion-proof Engine for receives the ambient air inlet and the condenser of the refrigerator, and that in the interior of the first housing connecting pipes, for. B. Stainless steel pipes, gas-tight connected to the housing, to the the cold-side connecting lines soldered that are to the external condenser with the second housing lead, whose housing wall with an ambient air outlet opening is provided.
Hiernach bildet das an den Schaltschrank angeflanschte Gehäuse aus einem dichtgeschweißten Gehäuse eine dichte Einheit, wobei in dieses geschweißte Gehäuse Edelstahlrohre eingeschweißt sind, an die die kälteseitigen Verbindungsleitungen angelötet sind, die zum externen Verflüssiger führen, der in einem gesonderten Gehäuse untergebracht ist, das z. B. auf das Gehäuse des Kühlgerätes aufgesattelt ist, während innerhalb des geschweißten Gehäuses Standardkomponenten eingesetzt werden, die keiner Ex-Zulassung bedürfen. Lediglich der Verflüssigerlüfter wird in Ex-Ausführung benötigt.hereafter forms the flanged to the cabinet housing a tightly welded casing a sealed unit, with welded stainless steel tubes in this welded housing, to the cold-side Soldered connecting cables that are to the external condenser lead, the in a separate housing is housed, the z. B. is saddled on the housing of the refrigerator, while within of welded housing standard components be used, which do not require ex-approval. Only the condenser fan is in Ex version needed.
