Einrichtung zur Kühlung von elektrischen Maschinen.
EMI1.1
Die Spulenköpfe 18, 19 des ruhenden, sowie 20, 21 des umlaufenden Teiles befinden sich in den mit Kühlflüssigkeit gefüllten Räumen 22, 23 bzw. 24, 25 der Gehäuse, so dass ihnen eine wirksame Kühlung zuteil wird. Zur Kühlung der Eisenkerne 13, 26 sind in diesen-wie bei der Luftkühlung-in der Wellenrichtung verlaufende : Nuten 27, 28, 29, Bohrungen 30, Langlöcher. 31 usw. (Fig. 8) oder zwischen den Blechpaketen 32 senkrecht zur Welle verlaufende Spalte 33 (Fig. l) ausgebildet, durch welche das Kühlmittel von einem Flüssigkeitsraum in den andern geleitet wird.
Um die Wicklungen. 34 und 35 durch die Kühlflüssigkeit unmittelbar bestreichen zu lassen, sind dieselben in den Nuten 36 und 37 der Eisenkerne unter Belassung eines freier Durehtrittsquerschnittes für die Kühlflüssigkeit angeordnet. Als solche freie Durchtrittsquerschnitte können entsprechende Ausschnitte 27, 28 der Nuten 38 (Fig. 8), Aussparungen 39,40 im Leitermaterial selbst (Fig. 3 und 4), innerhalb der Isolation zwischen die Leiter eingesetzte Rohre 41 (Fig. 6), Zwischenräume 42, 43 und 44 zwischen mehreren innerhalb der Isolation untergebrachten Leitern (Fig. 5, 7 und 12) dienen.

EMI2.1
Bei der Ausführungsform nach Fig.
9 und 10, welche einen massiv ausgeführten umlaufenden Teil eines Turbogenerators darstellen, werden die seitlichen Flüssigkeitsräume statt durch die Ver- schalungen 16, 17 (Fig. 2) durch die Wellenflanschen 57, 58 gebildet. Ausserdem sind die Nuten 60 für
EMI2.2
zwischen einzelnen Leitern oder zwischen diesen und den Nutenwänden vorgesehen sind, ohne weiteres als Leitungen für das flüssige Kühlmittel verwendet werden können, so dass das Einziehen besonderer Rohre, wie nach Fig. 11 und 12, überflüssig wird.
Selbstverständlich kann man statt eines zusammenhängenden Gehäuses für die Kühlflüssigkeit

Device for cooling electrical machines.
EMI1.1
The coil heads 18, 19 of the stationary part and 20, 21 of the rotating part are located in the spaces 22, 23 and 24, 25 of the housing, which are filled with cooling liquid, so that they are effectively cooled. To cool the iron cores 13, 26, grooves 27, 28, 29, bores 30, elongated holes are provided in them — as in the case of air cooling — running in the direction of the shaft. 31 etc. (Fig. 8) or between the laminated cores 32 perpendicular to the shaft extending column 33 (Fig. 1) is formed, through which the coolant is passed from one liquid space into the other.
Around the windings. 34 and 35 can be coated directly by the cooling liquid, the same are arranged in the grooves 36 and 37 of the iron cores leaving a free passage cross section for the cooling liquid. Corresponding cutouts 27, 28 of the grooves 38 (FIG. 8), recesses 39, 40 in the conductor material itself (FIGS. 3 and 4), pipes 41 (FIG. 6) inserted between the conductors within the insulation, and spaces can be used as such free passage cross-sections 42, 43 and 44 are used between several conductors housed within the insulation (FIGS. 5, 7 and 12).

EMI2.1
In the embodiment according to Fig.
9 and 10, which represent a solid circumferential part of a turbo generator, the lateral liquid spaces are formed by the shaft flanges 57, 58 instead of the casings 16, 17 (FIG. 2). In addition, the grooves 60 are for
EMI2.2
are provided between individual conductors or between these and the groove walls, can easily be used as lines for the liquid coolant, so that the drawing in of special tubes, as shown in FIGS. 11 and 12, is superfluous.
Of course, instead of a cohesive housing for the cooling liquid

PATENT CLAIMS:
1. Device for cooling electrical machines by means of liquid, characterized in that the stationary fi 3) and the rotating part (26) have their own, exclusively for the
