  Kühleinrichtung für Transformatoren, insbesondere von   Schweiss-oder Erwärmungs-   maschinen. 



   Es ist bekannt, die Kühlung der Transformatoren elektrischer   Schweiss-oder Erwärmungsmaschinen   in der Weise auszuführen, dass man durch die hohlen Leiter der Ober-oder Unterspannungswicklung ein Kühlmittel strömen lässt. Auch ist es bekannt, Kühlrohre mit den Windungen der Wicklung selbst gleichlaufend zu verlegen. Diese Einrichtungen haben aber den Nachteil, dass die Kühlkörper unter Spannung stehen oder ihr Einbau verwickelt ist und durch Beschädigungen der Kühlrohre leicht grössere Betriebsstörungen entstehen. 



   Gemäss der Erfindung wird in einfacher und betriebssicherer Weise eine wirksame Kühlung der Transformatoren für Schweiss- oder Erwärmungsmaschinen dadurch erreicht, dass zwischen den Spulen der in bekannter Weise unterteilten Transformatorwicklung Kühlrohrbündel angeordnet sind, die mit gut leitendem Stoff zu Blöcken vergossen sind. 



   Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. 



   Fig. 1 zeigt die Teilansioht eines Transformators mit Kühlkörpern, Fig. 2 einen Schnitt durch die   Kühlkörper   nach Linie. A-B. 



   Zwischen den Transformatorspulen, d. h. zwischen den   Hochvoltspulen     a   und den Lappen e der Niedervoltspule sind Kühlrohre b angeordnet, welche zur besseren Wärmeleitung in Aluminiumkörper c eingegossen sind, wodurch zugleich Rohrgruppen zu Blöcken zusammengefasst werden, die leicht einzubauen sind. Zur Vermeidung von   Kurzschlüssen   befinden sieh zwischen den Spulen a bzw. e und den 
 EMI1.1 
 weise sehlangenförmig um die Spulen a geführt sind, fliesst die Kühlflüssigkeit in Pfeilrichtung.

  Cooling device for transformers, in particular for welding or heating machines.



   It is known to cool the transformers of electrical welding or heating machines in such a way that a coolant is allowed to flow through the hollow conductors of the high or low voltage winding. It is also known to lay cooling tubes in the same direction as the turns of the winding itself. However, these devices have the disadvantage that the heat sinks are under tension or their installation is complicated, and damage to the cooling tubes can easily result in major malfunctions.



   According to the invention, an effective cooling of the transformers for welding or heating machines is achieved in a simple and operationally reliable manner in that cooling tube bundles are arranged between the coils of the transformer winding, which is subdivided in a known manner and which are cast into blocks with highly conductive material.



   An embodiment of the invention is shown in the drawing.



   Fig. 1 shows the partial view of a transformer with heat sinks, Fig. 2 shows a section through the heat sinks along the line. FROM.



   Between the transformer coils, d. H. Between the high-voltage coils a and the tabs e of the low-voltage coil, cooling tubes b are arranged, which are cast into aluminum bodies c for better heat conduction, whereby tube groups are also combined into blocks that are easy to install. To avoid short circuits, see between the coils a or e and the
 EMI1.1
 are guided around the coils a in the form of a string, the cooling liquid flows in the direction of the arrow.

Diese Anordnung gestattet es, die Transformatorenspulen a und e mit den Kühlkörpern b, c eng zusammenzubauen, wodurch eine innige Berührung und somit eine gute Wärmeableitung von den Transformatorenspulen zu den Kühlkörpern erreicht wird. Auf diese Weise ist eine Temperaturverminderung mittels der Kühltlüssigkeit möglich und wird eine grössere Lebensdauer der Transformatorenspulen erreicht PATENT-ANSPRUCH : Kühleinrichtung für Transformatoren, insbesondere von Schweiss- oder Erwärmungsmaschinen, EMI1.2 **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. This arrangement makes it possible to assemble the transformer coils a and e closely together with the heat sinks b, c, whereby an intimate contact and thus good heat dissipation from the transformer coils to the heat sinks is achieved. In this way, a temperature reduction is possible by means of the cooling liquid and a longer service life of the transformer coils is achieved PATENT CLAIM: Cooling device for transformers, in particular for welding or heating machines, EMI1.2 ** WARNING ** End of CLMS field may overlap beginning of DESC **.
