 schwindigkeit stark beeinflusst wird. Die Änderung der Flammengeschwindigkeit bei einer Verbrennung beeinflusst aber wiederum den Druck, wodurch die Wirkung der erfindungsgemässen Kühlbleche auch in einem vollständig verschlossenen Gehäuse gegeben ist, welches keine Verbindung mit der Aussenluft aufweist. 



   - Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. 



   Fig. 1 zeigt einen Schnitt durch ein druckfestes Gehäuse mit zwei Kühlblechen. Der Deckel l des Gehäuses ist mit dem Unterteil 2 des Gehäuses fest verbunden. Die Flanschen 4 sind deutlich zu erkennen. 



  Die zwei Kühlbleche sind mit 3 bezeichnet. 



   Fig. 2 zeigt ein Kühlblech 3, in Frontansicht, man erkennt eine Grundplatte und darauf befestigte Rippenbleche. 



   Fig. 3 zeigt ein Kühlblech 3 in Seitenansicht. 



   Die Kühlbleche sind in das druckfeste Gehäuse eingeschraubt, u. zw. so, dass sie die Einbaugeräte nicht stören. Durch die wesentlich vergrösserte Oberfläche im Inneren des Gehäuses wird die vorher beschriebene Wirkung der Temperatur-und Druckverminderung erzielt.

1.   DruckfestesGehäuse   für   elektrische Schaltgeräte mit Schutzeinrichtung   gegen Schlagwetter   u. dgl.   



  Explosionen unter Verwendung von Kühlblechen, dadurch gekennzeichnet, dass die Kühlbleche in seinem Inneren eingebaut sind und in bezug auf die Gehäuseabmessung eine grosse Oberfläche aufweisen.

 speed is strongly influenced. The change in the flame speed during combustion, however, in turn influences the pressure, whereby the effect of the cooling plates according to the invention is also given in a completely closed housing which has no connection with the outside air.



   - An embodiment of the invention is shown in the drawing.



   Fig. 1 shows a section through a pressure-resistant housing with two cooling plates. The cover l of the housing is firmly connected to the lower part 2 of the housing. The flanges 4 can be clearly seen.



  The two cooling plates are labeled 3.



   Fig. 2 shows a cooling plate 3, in front view, one recognizes a base plate and ribbed plates attached to it.



   Fig. 3 shows a cooling plate 3 in side view.



   The cooling plates are screwed into the pressure-resistant housing, u. so that they do not interfere with the built-in appliances. The previously described effect of reducing the temperature and pressure is achieved by the significantly enlarged surface inside the housing.



    PATENT CLAIMS:
1. Pressure-resistant housing for electrical switchgear with protection against firedamp and like



  Explosions using cooling plates, characterized in that the cooling plates are built into its interior and have a large surface in relation to the housing dimensions.
