  Wellblechbehälter für Transformatoren und elektrische Apparate. 



   Es ist bekannt, bei elektrischen Apparaten die Wärmeabfuhr durch   Geblasen   mit Luft zu verbessern und dabei die Luft aus Düsen so austreten zu lassen, dass auch die den Apparat umgebende ruhende Luft in Bewegung gebracht und so zur Wärmeableitung ausgiebiger herangezogen wird. 



   Bei den besonders im Transformatorenbau üblichen Wellblechbehältern kann man die so erzielte Kühlwirkung erheblich verbessern, wenn man dafür sorgt, dass die Kühlluft tief zwischen die Blechwellen eintritt und in ihnen energisch   hochgeführt   wird. Nach der Erfindung erreicht man das, indem man die Austrittsöffnungen für die Kühlluft so anordnet, dass die Luft in mindestens zwei Richtungen austritt, von denen die eine im wesentlichen waagrecht verläuft, so dass die Luft tief in die Wellen hineingeblasen 
 EMI1.1 
 eine Saugwirkung ausgeübt wird. 



   Die Erfindung sei an Hand der Zeichnung beschrieben.   Fig. l zeigt   einen Horizontalschnitt, Fig. 2 einen Vertikalschnitt durch einen mit der neuen   Einrichtung versehenen Wellblechkasten.   a ist der Behälter mit den Blechwellen b. In einer gewissen Höhe umgibt den Behälter ein rohrförmiger Kasten e, dem bei   d Kühlluft durch   einen Ventilator zugeführt wird. Der Kasten ist mit zwei Reihen von Öffnungen e und f versehen. Durch die Öffnungen e wird die   Kühlluft   horizontal in die Wellen hineingeblasen, während die aus den   Öffnungen/schräg nach   oben austretenden Luftstrahlen auf die Luft in den Wellen saugend einwirken und sie hochsteigen lassen. 



   Versuche haben ergeben, dass die neue Anordnung   ausserordentlich   wirksam ist, weil das sonst beobachtete Kleben der Luft in tiefen Wellen erfolgreich bekämpft wird.

  Corrugated iron containers for transformers and electrical apparatus.



   It is known to improve the dissipation of heat in electrical apparatus by blowing with air and thereby to let the air escape from nozzles in such a way that the static air surrounding the apparatus is also set in motion and thus used more extensively for heat dissipation.



   In the case of corrugated iron containers, which are particularly common in transformer construction, the cooling effect achieved in this way can be significantly improved if one ensures that the cooling air enters deep between the sheet metal shafts and is energetically carried up in them. According to the invention, this is achieved by arranging the outlet openings for the cooling air so that the air exits in at least two directions, one of which is essentially horizontal, so that the air is blown deep into the waves
 EMI1.1
 suction is exerted.



   The invention is described with reference to the drawing. Fig. 1 shows a horizontal section, Fig. 2 shows a vertical section through a corrugated iron box provided with the new device. a is the container with the sheet metal shafts b. At a certain height, the container is surrounded by a tubular box e, to which cooling air is supplied by a fan at d. The box is provided with two rows of openings e and f. The cooling air is blown horizontally into the waves through the openings e, while the air jets emerging from the openings / diagonally upwards have a suction effect on the air in the waves and allow it to rise.



   Tests have shown that the new arrangement is extremely effective because the otherwise observed sticking of the air in deep waves is successfully combated.
