Description
Die Erfindung bezieht sich auf eine flüssigkeitsgekühlte, geschlossene elektrische Maschine mit einer die durch Lüfter umgewälzte Innenluft rückkühlenden Vorrichtung, die aus dem an dem Ständerblechpaket unmittelbar anliegenden doppelwandigen Gehäuse und einem an dem Läuferblechpaket unmittelbar anliegenden, hohl ausgeführten Wellenteil besteht, bei der als Lüfterflügel dienende mit großer Wärmeübergangsfläche mit der Hohlwelle verbundene Kühlrippen sich etwa über den freien Raum zwischen Läuferwicklung und Lager erstrecken und bis zum Läuferdurchmesser reichen, nach Patent 928 186.The invention relates to a liquid-cooled, closed electrical machine with an internal air that is circulated by the fan recooling Device, which consists of the double-walled directly adjacent to the stator core Housing and a hollow executed directly adjacent to the laminated rotor core There is a shaft part, which serves as a fan blade with a large heat transfer surface with the hollow shaft connected cooling fins about the free space between The rotor winding and bearing extend and extend to the rotor diameter, after Patent 928 186.
Die Erfindung hat die Aufgabe, die Kühlwirkung bei einer solchen Maschine weiter zu steigern. Erfindungsgemäß bestehen die Lüfterflügel aus einem Material hoher Wärmeleitfähigkeit, insbesondere aus Aluminium, und sind mit nahezu voller Flügelbreite an einer Lüfternabe gut wärmeleitend befestigt.The invention has the task of improving the cooling effect in such a machine to increase further. According to the invention, the fan blades are made of one material high thermal conductivity, especially made of aluminum, and are almost full with Blade width attached to a fan hub with good thermal conductivity.
Die Erfindung soll an Hand des in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert werden. Sie zeigt einen Teil einer elektrischen Maschine im Längsschnitt.The invention is based on the embodiment shown in the drawing are explained in more detail. It shows part of an electrical machine in longitudinal section.
Das Ständergehäuse I einer elektrischen Maschine ist doppelwandig hohl ausgeführt und der so gebildete, an eine Rohrleitung angeschlossene Hohlraum 2 mit Kühlflüssigkeit, insbesondere Wasser, gefüllt. Auf dem hohl ausgeführten und ebenfalls mit Kühlflüssigkeit gefüllten Wellenteil 3 ist zu beiden Seiten des Läuferblechpaketes 4 je ein Lüfter angeordnet, der aus der Nabe 5 und den Lüfterflügeln 6 besteht. Die Lüfterflügel, die aus einem Material hohe Wärmeleitfähigkeit, insbesondere Aluminium, gefertigt sind, sind großflächig und erstrecken sich einerseits nahezu über die gesamte Axiallänge des Wickelkopfraumes und andererseits bis an den Außendurchmesser des Läuferblechpaketes 4. Die Lüfterflügel gehen mit nahezu voller Flügelbreite in die mit ihnen aus einem Stück bestehende Nabe 5 über.The stator housing I of an electrical machine is double-walled executed hollow and the thus formed, connected to a pipeline cavity 2 filled with cooling liquid, in particular water. On the hollow and Shaft part 3, also filled with coolant, is on both sides of the laminated rotor core 4 each a fan is arranged, which consists of the hub 5 and the fan blades 6. The fan blades, which are made of a material with high thermal conductivity, in particular aluminum, are made, are large and extend on the one hand almost over the total axial length of the winding head space and on the other hand up to the outer diameter of the rotor laminated core 4. The fan blades go with almost the full blade width into the hub 5 consisting of one piece with them.
Die Erfindung ermöglicht den Lüftern derartiger flüssigkeitsgekühlter Maschinen die Erfüllung zweier Aufgaben: sie dienen nicht nur zum Umwälzen der Luft in den Wickelkopfräumen, sondern auch durch unmittelbare Ableitung der Wärme an die kalte Welle als Rückkühlvorrichtung.The invention enables the fans of such liquid-cooled Machines fulfill two tasks: They are not only used to circulate the air in the winding head spaces, but also through the direct dissipation of heat the cold wave as a cooling device.
