Description

Die Erfindung betrifft ein- insbesondere aus Spritzguß bestehendes Gehäuse für elektrische Maschinen, das unter Freilassung von Kühlmittelwegen mit dem in ihm gelagerten Blechpaket durch Stege verbunden ist. Es ist bereits bekannt, um eine gute Abführung der von dem Ständerblechpaket auf das Gehäuse übergehenden Wärmemenge zu erreichen, das Gehäuse auf der Außenseite mit Rippen zu versehen, die die Wärme in verstärktem Maß an die Außenluft abgeben. Solche auf der Außenseite des Gehäusemantels angebrachten Rippen haben jedoch den Nachteil, daß sie den Durchmesser der elektrischen Maschine nicht unerheblich vergrößern, so daß hierdurch räumliche Schwierigkeiten bei der Unterbringung der Maschine entstehen können. Im folgenden wird nun ein Mittel gezeigt, durch das man eine erhöhte Wärmeabfuhr auch bei einem nicht mit solchen Rippen versehenen Gehäuse erzielen kann.The invention relates to a particular one consisting of injection molding Housing for electrical machines, leaving coolant paths with the laminated core stored in it is connected by webs. It is already known a good dissipation of the overflowing from the stator core on the housing To achieve the amount of heat, to provide the housing with ribs on the outside, which give off the heat to the outside air to a greater extent. Those on the outside The housing jacket attached ribs have the disadvantage that they have the diameter enlarge the electrical machine not insignificantly, so that spatial Difficulties in accommodating the machine can arise. Hereinafter a means is now shown, by which one can increase heat dissipation even with a can achieve housing not provided with such ribs.

Gemäß der Erfindung ist das Gehäuse in der Weise ausgebildet, daß der Gehäusemantel auf der die Kühlmittelwege begrenzenden Innenseite mit seine Oberfläche vergrößernden Wellungen od. dgl. versehen ist. Bei einem in solcher Weise ausgebildeten Spritzgußgehäuse wird durch die in das Gehäuse miteingespritzten Aluminiumrippen eine gute Abfuhr der Wärme in die durch die Kühlmittelwege strömende Kühlluft erzielt, so daß in den meisten Fällen besondere Außenrippen an dem Gehäuse erspart werden können.According to the invention, the housing is designed in such a way that the housing jacket on the inside delimiting the coolant paths with its surface Enlarging corrugations or the like. Is provided. With one trained in this way The injection-molded housing is created by the aluminum ribs that are also injected into the housing Good dissipation of heat into the cooling air flowing through the coolant channels is achieved, so that special outer ribs on the housing are saved in most cases can.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. Das Ständerblechpaket r hat verschiedenartig ausgebildete Sektoren, und die an das Blechpaket angrenzenden Teile des Spritzgußmantels sind ebenfalls zur Veranschaulichung verschiedener Ausführungsmöglichkeiten verschieden dargestellt. So ist der Spritzgußmantel 2 ibei 3 unmittelbar auf eine Ecke :des Blechpaketes aufgesetzt unter Bildung von Stegen. Bei 4 sind die Stege fortgelassen, und bei 5 wurde ein die Wärme besonders gut leitender Übergang zwischen Blechpaketrücken und Mantel dargestellt. Bei 7 sitzt der Spritzgußmantel auf einem schwalbenschwanzförmig geschnittenen Teil des Blechpaketes. Bei. 8 hat das Blechpaket besondere Stege; die Kühlmittelwege, die vorzugsweise zum Durchleiten von Kühlluft dienen, sind mit 9 bezeichnet und haben ebenfalls verschiedene Formen.The drawing shows an embodiment of the subject matter of the invention shown. The stator core r has differently designed sectors, and the parts of the injection-molded jacket adjoining the laminated core are also to illustrate different design options shown differently. So the injection-molded jacket 2 ibei 3 is directly on one corner: the laminated core put on with the formation of webs. At 4 the webs are omitted, and at 5, a transition between the laminated core backs that conducts heat particularly well and coat shown. At 7 the injection molded jacket sits on a dovetail shape cut part of the laminated core. At. 8 the laminated core has special webs; the coolant paths, which are preferably used for the passage of cooling air, are with 9 and also have different shapes.

Die Innenseite des Mantels ist nun, wie bei einem dieser Kühlmittelwege 9 dargestellt ist, mit Wellungen6 versehen, welche die Oberfläche der Innenwand des Gehäuses an dieser Stelle vergrößern und dadurch für einen erheblich verbesserten Wärmeübergang der von der Maschine erzeugten Wärme an die durch die Kühlmittelwege 9 hindurchgehende Kühlluft sorgen.The inside of the jacket is now like one of these coolant paths 9 is shown, provided with corrugations6, which the surface of the inner wall of the housing enlarge at this point and thus for a considerably improved Heat transfer of the heat generated by the machine to the heat generated by the coolant paths 9 ensure that cooling air passes through.
