Description

Völlig geschlossene elektrische Maschine mit Kühlung :durch einen völlig abgeschlossenen Innenluftstrom und einen diesen rückkühlenden Außenluftstrom. Es ist bekannt, völlig geschlossene elektrische Maschinen in der Weise zu kühlen, daß ein im Innern der Maschine kreisender Luftstrom von einem Außenluftstrom rückgekühlt wird, der durch den Mantel der Maschine getrieben wird. Bei einer solchen Einrichtung wird z. B. der Innenluftstrom nur an einem begrenzten Teil des Umfanges rückgekühlt und der Außenluftstrom umspült außerdem -den Gehäuserücken, indem er in peripherischer Richtung um die Maschine geführt ist.Completely closed electrical machine with cooling: by one Completely closed inside air flow and an outside air flow that cools this back. It is known to cool completely closed electrical machines in such a way that that an air flow circulating inside the machine is recooled by an outside air flow which is driven through the jacket of the machine. With such a facility is z. B. the internal air flow is only recooled on a limited part of the circumference and the outside air flow also flows around the back of the housing by moving in more peripheral Direction is guided around the machine.

Gemäß der Erfindung kann die Rückkühlung der Innenluft fast am ganzen Umfang der Maschine erfolgen und trotzdem -der Gehäuserücken ausgiebig durch Außenluft gekühlt werden, @cladurch, daß ,die Innenluft über am Umfang verteilte Querkanäle zwischen den Außenluftkanälen hindurch nach einem Raum geleitet wird, der von zwei Seiten von Außenluft umgeben ist, und durch den von Außenluft durchströmte Rohre führen.According to the invention, the recooling of the indoor air can be done almost entirely The circumference of the machine takes place and nevertheless the back of the housing is extensively exposed to outside air be cooled, @c by the fact that, the inside air via transverse channels distributed around the circumference between the outside air ducts through to a room that is divided by two Sides is surrounded by outside air, and through the pipes through which outside air flows to lead.

Die Fig. T und 2 zeigen in Längs- und Querschnitten ein Beispiel der Anordnung. Die Außenluft strömt durch die Eintrittslöcher a in achsialerRichtung durch Kanäle b, die durch den Ständerblech- und Gehäusegußrücken gebildet sind. Die Innenluft wird über kurze Querkanäle d in achsialer Richtung durch deil Raum e geführt, der zwischen Gehäusegußrücken und Abdeckblech f liegt und durch den die gleichfalls von Außenluft durchströmten Rohre c führen.FIGS. T and 2 show an example of the arrangement in longitudinal and cross sections. The outside air flows through the inlet holes a in the axial direction through channels b, which are formed by the back of the stator sheet metal and the cast housing. The inside air is guided in the axial direction via short transverse channels d through the space e, which lies between the cast housing back and cover plate f and through which the pipes c, which are likewise traversed by outside air, lead.
