Description
Die Erfindung betrifft einen einteiligen ringförmigen Wärmetauscher nach dem Oberbegriff des Patentan-Spruches. The invention relates to a one-piece annular heat exchanger according to the preamble of the patent claim.
Ein solcher Wärmetauscher aus Nichteisenmetall ist aus der bekanntgemachten deutschen Patentanmeldung A7456 VIIId/21d'-18.6.53 bekannt. Dabei wird das Ständerblechpaket mit dem Wärmetauscher umgössen, in dem die Kühlrohre eingebettet sind. Das Ständerblechpaket kann dabei wegen der auftretenden Erwärmung durch das umgossene heiße Material nur im unbewickelten Zustand mit dem Wärmetauscher bestückt werden. Eine Entfernung des Wärmetauschers zu Reparaturzwecken ist dabei ohne nachteilige Auswirkungen auf den Ständer und den Wärmetauscher nicht erreichbar, da eine Erhitzung allein des Wärmetauschers nicht ersichtlich ist.Such a heat exchanger made of non-ferrous metal is from the known German patent application A7456 VIIId / 21d'-6/18/53 known. The stator core with the heat exchanger is cast around it, in which the cooling tubes are embedded. The stator core can because of the heating that occurs Due to the encapsulated hot material, it is only fitted with the heat exchanger when it is not wound will. Removing the heat exchanger for repair purposes has no adverse effects on the stand and the heat exchanger cannot be reached, since the heat exchanger alone is not heated can be seen.
Die Bestückung eines bewickelten Ständerblechpaketes ist mit einem aus dem DE-GM 19 73 004 bekannten mehrteiligen Wärmelauscher möglich, dessen einzelne Segmente auf ihren dem Ständerblechpaket zugewandten Seiten offene Nuten haben, die mit dem Blechpaketrücken Kühlluftkanäle bilden. Die Montage solcher zu-Sammengesetzter Wärmetauscher ist relativ aufwendig und ihre Kühlwirkung schlechter als die der erstgenannten einteiligen Wärmetauscher.A wound stator core is fitted with one known from DE-GM 19 73 004 multi-part heat exchanger possible, the individual segments of which face the stator core Sides have open grooves that form cooling air channels with the back of the laminated core. The assembly of such composite ones Heat exchanger is relatively expensive and its cooling effect is worse than that of the former one-piece heat exchanger.
Der Erfindung liegt die Aufgabe zugrunde, einen gesondert herstellbaren und einfach montierbaren Warmetauscher der erstgenannten Art zu schaffen, der leicht auf dem bewickelten Ständer aufgebracht bzw. von diesem entfernt werden kann.The invention is based on the object of providing a heat exchanger that can be produced separately and is easy to assemble of the first-mentioned type, which can be easily applied to the wound stand or can be removed from this.
Die Lösung der gestellten Aufgabe gelingt durch mit den Merkmalen im kennzeichnenden Teil des Patentan-Spruchs. The task at hand is achieved with the features in the characterizing part of the patent claim.
Ein Ausführungsbeispiel der Erfindung ist anhand der Zeichnung nachfolgend näher erläutert. Es zeigtAn exemplary embodiment of the invention is explained in more detail below with reference to the drawing. It shows
F i g. 1 einen teilweisen Längsschnitt undF i g. 1 shows a partial longitudinal section and
F i g. 2 einen teilweisen Querschnitt durch eine elektrische Maschine mit einem Wärmetauscher.F i g. 2 shows a partial cross-section through an electrical Machine with a heat exchanger.
Auf das bewickelte Ständerblechpaket 1 ist ein einteiliger, ringförmiger Wärmetauscher 2 aus Aluminium oder einem anderen gut wärmeleitenden Werkstoff aufgeschrumpft und dadurch ein hervorragender Wärmeübergang vom Ständerblechpaket zum Wärmetauscher erreicht. In dem Wärmetauscher sind ringsherum von der Außenluft durchströmte achsparallele Kühlrohre 3On the wound stator core 1 is a one-piece, ring-shaped heat exchanger 2 made of aluminum or another material that conducts heat well and is therefore an excellent heat transfer reached from the stator core to the heat exchanger. In the heat exchanger there are around from the outside air flowed through axially parallel cooling tubes 3
