Description

Elektrische Maschine mit doppelwandigem, von einer Kühlflüssigkeit durchströmtem Ständergehäuse Die Erfindung bezieht sich auf eine elektrische Maschine mit doppelwandigem, von einer Kühlflüssigkeit durchströmtem Ständergehäuse, dessen Innenwände im Bereich der Wickelkopfräume mit Kühlrippen versehen sind.Electric machine with double-walled, from a cooling liquid flow through stator housing The invention relates to an electrical machine with double-walled stator housing through which a cooling liquid flows, its Inner walls in the area of the winding head spaces are provided with cooling fins.

Die Erfindung beruht auf der Erkenntnis, daß die Kühlrippen eine weitere, für flüssigkeitsgekühlte elektrische Maschinen wichtige Aufgabe übernehmen können. Erfindungsgemäß bilden die Kühlrippen mit der Gehäusewand oder selbst Abflußrinnen für das Kondenswasser und überdecken dabei die Wickelköpfe.The invention is based on the knowledge that the cooling fins have a further, can take on important tasks for liquid-cooled electrical machines. According to the invention, the cooling fins form drainage channels with the housing wall or themselves for the condensation water and cover the winding heads.

Elektrische Maschinen mit eingebauten Abflußrinnen für das Kondenswasser sind an sich bekannt. Diese Abflußrinnen haben eine verhältnismäßig kleine Paulänge und fangen nur das an der kegelförmig ausgebildeten Innenwand des Gehäuses entlang gleitende Kondenswasser auf. Bei stärkerer Kondenswasserbildung besteht die Gefahr, daß ein Teil des Kondenswassers nicht mehr an der Gehäusewand entlang gleitet, sondern nach unten auf die Wickelköpfe abtropft. Eine Kühlwirkung haben diese Abflußrinnen nicht.Electric machines with built-in drainage channels for the condensation water are known per se. These drainage channels have a relatively small length and catch only that along the conical inner wall of the housing sliding condensation on. If there is a lot of condensation, there is a risk of that part of the condensation water no longer slides along the housing wall, but drips down onto the winding heads. These drainage channels have a cooling effect not.

In den Fig. 1 und 2 der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, und zwar in Fig. 1 ein Teil eines doppelwandigen Gehäusemantels einer elektrischen Maschine im Längsschnitt und in Fig. 2 im Querschnitt.In Figs. 1 and 2 of the drawing, an embodiment of the Invention shown, namely in Fig. 1 part of a double-walled housing shell an electrical machine in longitudinal section and in FIG. 2 in cross section.

Das Ständerblechpaket 1 einer nicht weiter dargestellten elektrischen Maschine ist nach Fig. 1 von dem doppelwandigen Gehäusemantel 2, der mit Kühlflüssigkeit gefüllt ist, unmittelbar umgeben. Im Bereich der Wickelkopfräume 3 und 4 sind an der Innenwand 5 des Gehäusemantels Kühlrippen .6 angeschweißt, um so durch Vergrößerung der Oberfläche die Rückkühlung der in den Wickelkopf räumen bewegten Innenluftströme zu verbessern.. Die Rippen sind, wie aus Fig. 2 hervorgeht, nicht alle radial, sondern so angeordnet, daß sie mit der inneren Gehäusewand 5 Abflußrinnen für die Kondensflüssigkeit bilden und so ein Abtropfen auf die Wicklungsköpfe verhindern. Das von den Rinnen abfließende Kondenswasser wird von Leitrinnen 8 aufgefangen, die an den Stirnseiten des Blechpaketes ringförmig angeordnet sind, und nach unten abgeleitet.The stator core 1 of an electrical not shown Machine is shown in Fig. 1 of the double-walled housing jacket 2, which is with cooling liquid is filled, immediately surrounded. In the area of the winding head spaces 3 and 4 are on the inner wall 5 of the housing jacket cooling ribs .6 welded to so by enlargement the surface the recooling of the internal air flows moving into the winding head to improve .. The ribs are, as can be seen from Fig. 2, not all radial, but arranged so that they with the inner housing wall 5 drainage channels for the condensation form and thus prevent dripping onto the winding heads. That from the gutters Drained condensation water is caught by guide channels 8 on the front sides of the laminated core are arranged in a ring, and derived downwards.
