Vorliegende Erfindung betrifft ein Ventilationsverfahren, welches für elektrische Maschinen ganz besondere Vorteile bietet, indem die den Strom führenden Leiter, in denen sich die schädliche Wärme entwickelt, als Rohre mit besonders gestalteten Enden ausgebildet werden.The present invention relates to a ventilation method which is used for electrical machines offers very special advantages by having the current-carrying conductors in which the harmful heat develops as Tubes can be formed with specially designed ends.
Durch die besondere Gestaltung der Enden dieser Rohre wird nun Luft gezwungen, mitDue to the special design of the ends of these tubes, air is now forced with it
ίο großer Geschwindigkeit durch diese als Rohre gebildeten Leiter zu strömen, was eine ganz beträchtliche Kühlung zur Folgeίο great speed to flow through this ladder formed as tubes, what a very considerable cooling result
hat. . ■Has. . ■
In beiliegender Zeichnung ist die Erfindung an fünf verschiedenen Ausführungsbeispielen im Schnitt dargestellt.In the accompanying drawing, the invention is shown in five different exemplary embodiments shown in section.
Das Rohr ist in allen Beispielen mit a, das die Rohre aufnehmende Eisen mit b, die Lufteinströmung mit c und die Ausströmungmit d bezeichnet.In all examples, the tube is designated with a, the iron holding the tubes with b, the air inflow with c and the outflow with d .
Rotiert z. B. der Teil b, so stellt man die linken Rohröffnungen c (Fig. 1 und 2) im Sinne der Bewegungsrichtung, so daß die Luft in die Rohre strömen muß. Da aber das andere" Ende seine öffnung d in entgegengesetztem Sinne hat, so saugt die äußere Luft die in den Rohren befindliche Luft heraus, verstärkt also die Wirkung der linken Seite.Rotates z. B. the part b, so one sets the left pipe openings c (Fig. 1 and 2) in the sense of the direction of movement, so that the air must flow into the pipes. However, since the other "end" has its opening d in the opposite direction, the outside air sucks out the air in the tubes, thus increasing the effect of the left side.
In den Fig. 3 und 4 sind beide Enden so gerichtet, daß sie Luft schöpfen, die durch die Mitte der Rohre entweicht und beliebig durch einen anderen Maschinenteil e hindurch-In FIGS. 3 and 4, both ends of which are directed so that they draw air escaping through the center of the tubes and any other machine part by an e hindurch-

In Fig. 5 endlich strömt die Luft in der Mitte in das Rohr und bespült dann die Außenseiten des Teiles e. Die Wicklung wird bei f weitergeführt. Diese Beispiele ließen' sich noch beliebig vermehren.In Fig. 5, finally, the air flows in the middle into the tube and then flushes the outside of part e. The winding continues at f . These examples could be multiplied at will.
