Description

Die Erfindung betrifft eine elektrische Maschine mit einer in der Gehäusewand des Ständergehäuses eingegossenen Kühlrohr­ schlange.The invention relates to an electrical machine with a the housing wall of the stator housing cast-in cooling tube Snake.

Eine solche Maschine ist durch das DE-U-91 07 197 bekannt. Bei dieser bekannten Maschine, deren Gehäuse aus Grauguß be­ steht, ist eine Stahlrohrschlange in die Gehäusewand des Ma­ schinengehäuses eingegossen.Such a machine is known from DE-U-91 07 197. In this known machine, the housing made of cast iron be stands, is a tubular steel coil in the housing wall of the Ma cast housing.

Der Erfindung liegt die Aufgabe zugrunde, bei einer solchen Maschine die Wärmeableitung noch wesentlich zu verbessern.The invention is based, with such an object Machine to significantly improve heat dissipation.

Dies gelingt nach der Erfindung dadurch, daß die Gehäusewand aus Aluminium oder einer Aluminiumlegierung und die Kühlrohr­ schlange aus Aluminium bzw. einer Aluminiumlegierung oder aus Kupfer bzw. einer Kupferlegierung bestehen. Da derartige Alu­ minium- bzw. Kupfermaterialien eine sehr gute Wärmeleitfähig­ keit besitzen, ist auch eine sehr gute Wärmeableitung vom Ständer der Maschine zu der im Maschinengehäuse eingegossenen Kühlrohrschlange gegeben. Weil die Gehäusewand und die Kühl­ rohrschlange aus obengenannten Materialien bestehen, ergeben sich auch keine Temperatursprünge an den Übergangsstellen zwischen der Gehäusewand und der Kühlrohrschlange. Dies gilt insbesondere dann, wenn die Gehäusewand und die Kühlrohr­ schlange aus gleichem Material bestehen. This is achieved according to the invention in that the housing wall Made of aluminum or an aluminum alloy and the cooling pipe snake made of aluminum or an aluminum alloy or Copper or a copper alloy exist. Since such aluminum minium or copper materials have a very good thermal conductivity possessing is also a very good heat dissipation from Stand of the machine to that cast in the machine housing Given cooling pipe coil. Because the housing wall and the cooling Rohrschlange consist of the above materials, result there are no temperature jumps at the transition points between the housing wall and the cooling coil. this applies especially when the housing wall and the cooling pipe snakes are made of the same material.  

Die Integration der Kühlrohrschlange in die Gehäusewand des Maschinengehäuses führt bei einer Maschine mit einem mehrec­ kigen Gehäusequerschnitt zu keiner Vergrößerung der äußeren Abmessungen des Maschinengehäuses, wenn die Kühlrohrschlange in den Eckbereichen des Maschinengehäuses in Längsrichtung des Maschinengehäuses verlaufend angeordnet und die Rohrver­ bindung von einem Eckbereich zu dem anderen Eckbereich axial vor dem Ständerblechpaket liegend in der Gehäusewand vorgese­ hen ist.The integration of the cooling pipe coil in the housing wall of the Machine housing leads on a machine with a mehrec The housing cross section does not enlarge the outer Dimensions of the machine housing when the cooling coil in the corner areas of the machine housing in the longitudinal direction of the machine housing arranged trending and the Rohrver binding axially from one corner area to the other corner area pre-lying in front of the stator core in the housing wall hen is.

Anhand eines in der Zeichnung dargestellten Ausführungsbei­ spieles wird die Erfindung nachfolgend näher beschrieben. Es zeigen:Based on an exemplary embodiment shown in the drawing game, the invention is described in more detail below. It demonstrate:

Fig. 1 das Gehäuse einer elektrischen Maschine im längs­ schnitt und Fig. 1, the housing of an electrical machine in longitudinal section and

Fig. 2 eine Stirnansicht des Gehäuses nach Fig. 1. Fig. 2 is an end view of the housing of FIG. 1.

Mit 1 ist das Ständergehäuse einer elektrischen Maschine be­ zeichnet. In diesem Ständergehäuse 1 ist ein aus einer Viel­ zahl von aufeinander geschichteten Blechlamellen bestehendes Ständerblechpaket 2 angeordnet. Das Ständergehäuse 1 ist meh­ reckig ausgebildet. In den über das runde Ständerblechpaket 2 überstehenden Eckbereichen 3 des Ständergehäuses 1 ist eine Kühlrohrschlange 4 angeordnet.With 1 the stator housing of an electrical machine is characterized. In this stator housing 1 , a stator core 2 consisting of a large number of laminated laminations is arranged. The stator housing 1 is rectangular. A cooling pipe coil 4 is arranged in the corner regions 3 of the stator housing 1 which protrude beyond the round stator core 2 .

Diese Kühlrohrschlange weist zwei axial gegenüber der einen Stirnseite 5 des Ständergehäuses 1 vorstehende Anschlußenden 6 auf. Die Kühlrohrschlange 4 verläuft in dem Ständergehäuse 1 mäanderförmig. In jedem Eckbereich 3 sind zwei parallel verlaufende Rohrabschnitte 7 der Kühlrohrschlange 4 angeord­ net. Auf der der einen Stirnseite 5 gegenüberliegenden Seite sind die jeweils einem Eckbereich zugeordneten beiden Rohrab­ schnitte 7 über einen Rohrbogen 8 miteinander verbunden. Die Rohrbögen 8 und die Rohrabschnitte 7 können einstückig ausge­ bildet sein. In dem Bereich der einen Stirnseite des Ständer­ gehäuses 1 sind sich von einem Eckbereich 3 zu dem anderen Eckbereich 3 erstreckende Verbindungsrohre 9 axial vor dem Ständerblechpaket 2 liegend angeordnet. Über diese Verbin­ dungsrohre 9 sind die jeweils in einem Eckbereich liegenden Rohrabschnitte 7 mit den Rohrabschnitten 7 des jeweils ande­ ren Eckbereiches 3 so verbunden, daß sich insgesamt ein mäan­ derförmiger Verlauf der Kühlrohrschlange 4 ergibt. Da sich die Kühlrohrschlange 4 somit durchgehend unterbrechungslos zwischen ihren beiden Anschlußenden 6 erstreckt, bestehen keinerlei Dichtungsprobleme. Die Kühlrohrschlange 4 wird beim Gießen des Ständergehäuses 1 in dieses mit eingegossen und besteht aus obengenannten Materialien.This cooling tube coil has two connection ends 6 projecting axially relative to one end face 5 of the stator housing 1 . The cooling pipe coil 4 runs in a meandering manner in the stator housing 1 . In each corner area 3 , two parallel pipe sections 7 of the cooling coil 4 are net angeord. On the one end face 5 opposite side, the two pipe sections 7 each assigned to a corner area are connected to one another via a pipe bend 8 . The pipe bends 8 and the pipe sections 7 can be formed in one piece. In the area of one end face of the stator housing 1 , connecting tubes 9 extending axially in front of the stator core 2 are arranged from a corner area 3 to the other corner area 3 . About this connec tion pipes 9 , each lying in a corner area pipe sections 7 are connected to the pipe sections 7 of each other ren corner area 3 so that overall a meandering course of the cooling coil 4 results. Since the cooling pipe coil 4 thus extends continuously between its two connection ends 6 , there are no sealing problems whatsoever. The cooling tube coil 4 is cast into the stator housing 1 when it is cast and consists of the above-mentioned materials.

Die beschriebene Anordnung der Kühlrohrschlange 4 im Ständer­ gehäuse 1 führt zu keinen Abmessungsvergrößerungen des Stän­ dergehäuses 1. Dadurch ergibt sich eine optimale Ausnutzung des Ständerblechschnittes in bezug auf die vorgegebene Achs­ höhe der Maschine.The described arrangement of the cooling coil 4 in the stand housing 1 does not lead to any size enlargement of the stan dergehäuses 1st This results in an optimal utilization of the stator sheet metal cut in relation to the specified axis height of the machine.
