Description

Einrichtung zur Wärmeableitung aus den aktiven Teilen von Transformatoren Das Patent 593 732 betrifft eine Einrichtung zfzr Wärmeableitung aus den aktiven Teilen von Transformatoren mit Röhrenwicklung, bei der zwischen die zu kühlenden Teile mit ihren Enden aus der Wicklung . herausragende Drähte, Streifen, Bleche o. dgl. aus gut wärmeleitendem Material eingeschoben sind und mit ihren vorstehenden Enden an großflächige Wärmeableiter, insbesondere an das mit Kühlrippen versehene metallische Gehäuse des elektrischen Apparats angeschlossen sind.Device for heat dissipation from the active parts of transformers Patent 593,732 relates to a device for dissipating heat from the active ones Parts of transformers with tube windings, in which between those to be cooled Parts with their ends out of the winding. protruding wires, strips, sheets o. The like. Are inserted from a highly thermally conductive material and with their protruding Ends to large-area heat sinks, in particular to the one provided with cooling fins metallic housings of the electrical apparatus are connected.

Die Erfindung betrifft eine weitere besonders zweckmäßige Ausgestaltung der Kühlanordnung nach dem obengenannten Patent.The invention relates to a further particularly expedient embodiment the cooling arrangement according to the above-mentioned patent.

Erfindungsgemäß wird zwecks Steigerung der Wärmeableitung aus der Wicklung auch der Eisenkern, der in bekannter Weise mit vorstehenden Wärmeableitteilen versehen ist, mit. den Enden dieser Teile an einen großflächigen Wärmeableiter, insbesondere an das mit Kühlrippen versehene Gehäuse des Apparats, angeschlossen.According to the invention, in order to increase the heat dissipation from the Winding also the iron core, which in a known manner with protruding heat dissipation parts is provided with. the ends of these parts to a large-area heat sink, in particular connected to the housing of the apparatus, which is provided with cooling fins.

Die Erfindung soll an Hand der Zeichnung näher= erläutert werden. Die Zeichnung zeigt einen: Wandlerkern der Manteltype in perspektivischer Darstellung, der aus sog. Dreifingerblechen r zusammengesetzt ist. Dabei sind die Dreifingerbleche derart geschachtelt, daß an ihren Jochen Spalte :z entstehen. In die Spalte :2 sind Wärmeableitungsbleche 3 eingefügt, die derart aus dem Eisenkern herausragen und eine solche Länge besitzen, daß sie beim Einfügen des mit der Spule versehenen Eisenkerns in das metallische Wandlergehäuse die an den entsprechenden Stellen blank gemachte Gehäusewand berühren. Die Befestigung der Bleche 2 am Eisenkern kann durch Auflöten, Nieten, durch Federung o. dgl. erfolgen. Die Erfindung kann auch bei anderen Kernformen angewendet werden; dabei empfiehlt es sich wie beim Ausführungsbeispiel die Form der Blechlamellen und ihre Schachtelung so zu wählen, daß an bestimmten Stellen zwischen den geschachtelten Blechen Schlitze vorhanden sind, in die die Wärmeableitteile eingeschoben werden kön nen. -Die Wärmeableitteile für die Wicklungen, wie sie im Patent 593 732 beschrieben sind, können auch konstruktiv mit den Wärmeableitteilen für den Eisenkern zusammengefaßt werden, indem man z. B. die halbzylindrischen Wärmeableitbleche im Ausführungsbeispiel des Hauptpatents mit vorspringenden Blechlappen auf dem Eisenkern aufliegen läßt.The invention is to be explained in more detail with reference to the drawing. The drawing shows a: converter core of the jacket type in a perspective view, which is composed of so-called three-finger sheets r. Here are the three-finger sheets nested in such a way that gaps: z appear on their yokes. In the column: 2 are Heat dissipation plates 3 inserted, which protrude from the iron core and have such a length that they are inserted when the iron core provided with the coil is inserted into the metallic converter housing which is made bare in the appropriate places Touch the housing wall. The fastening of the sheets 2 to the iron core can be done by soldering, Rivets, suspension or the like. The invention can also be applied to other core shapes be applied; Here, as in the exemplary embodiment, the shape is recommended to choose the sheet metal lamellas and their nesting so that at certain points there are slots between the nested metal sheets, into which the heat dissipation parts can be inserted. -The heat dissipation parts for the windings as they are in the Patent 593 732 are described, can also constructively with the heat dissipation parts are summarized for the iron core by z. B. the semi-cylindrical heat sink in the embodiment of the main patent with protruding sheet metal tabs on the iron core lets lie on.
