Description

Vorrichtung zum Kühlen von Wellblechbehältern für elektrische Apparate mittels Kühlluft Es ist bekannt, bei elektrischen Apparaten die Wärmeabfuhr durch Beblasen 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 herang-,zogen wird.Device for cooling corrugated metal containers for electrical apparatus by means of cooling air It is known to dissipate heat in electrical equipment To improve blowing with air and to let the air escape from nozzles in such a way that that the still air surrounding the apparatus is also set in motion and thus to the Heat dissipation is used more extensively.

Bei den besonders im Transformatorenhau üblichen Wellblechbehältern ergeben sich dadurch Schwierigkeiten,>daß beim B.cblasen die Luft nicht tief genug zwischen die Blechwellen eintritt oder daß sich an einzelnen Stellen ruhende Luftkissen bilden, die den Wärmefibergang erschweren.With the corrugated iron containers that are particularly common in transformer houses Difficulties arise because the air is not deep enough when blowing occurs between the sheet metal shafts or that there are static air cushions at individual points form that complicate the heat transfer.

Gemäß der Erfindung sind diese Schwierigkeiten dadurch überwunden, daß die Kühlluft in zwei Strömen gegen die Wandung des Behälters geblasen wird, von .denen der eine etwa senkrecht, der andere unter einem spitzen Winkel nach oben gegen die Wand gerichtet ist. Der senkrecht auf die Wand auftreffende Luftstrom dringt tief in die Wellen des Blechbehälters ein und setzt die dort befindlichen Luftschichten in Bewegung. Der schräg gerichtete Luftstrom ist dem senkrecht auftreffenden Luftstrom derart zugeordnet, daß die senkrecht aufgeblasene Luft nicht an derselben Stelle bleibt, sondern nach oben abgesaugt wird.According to the invention, these difficulties are overcome by that the cooling air is blown in two streams against the wall of the container, from which one is approximately perpendicular, the other at an acute angle upwards is directed against the wall. The airflow that hits the wall perpendicularly penetrates deep into the waves of the sheet metal container and sets the ones located there Layers of air in motion. The inclined airflow is the one that hits it vertically Air flow assigned in such a way that the vertically inflated air is not at the same Place remains, but is sucked upwards.

Die Erfindung sei an Hand der Zeichnung beschrieben. Abb. t zeigt einen Horizontalschnitt, Alb!b. a 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 e-in rohrförmiger Kasten c, dem bei d Kühlluft durch einen Ventilator zugeführt wird. Der Kasten ist mit zwei Reihen von Öffnungen e und f versehen. Durch die Öffnungen c wird die Kühlluft horizontal in die Wellen hineingeblasen, während die aus den Öffnungen f schräg nach oben austretenden Luftstrahlen auf die Luft in den Wellen saugend einwirken und sie hochsteigen lassen.The invention is described with reference to the drawing. Fig. T shows a horizontal section, Alb! B. a is 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 e is surrounded by a tubular box c, 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 c, while the air jets emerging from the openings f diagonally upwards have a sucking effect on the air in the waves and cause it to rise.

Versuche haben ergeben, daß die neue Anordnung außerordentlich wirksam ist, weil das sonst beobachtete Kleben .der Luft in tiefen Wellen erfolgreich bekämpft wird.Tests have shown that the new arrangement is extremely effective is because the otherwise observed sticking of the air in deep waves successfully combats it will.
