FRANZ PICHLER ? WEIZ (STEIERMARK). Kühleinrichtung für Transformatoren und Erregerapulen.
Es ist bekannt, dass der Materialaufwand für Wechsel- und Drehstromtransformatoren, sowie auch für die Erregerspulen an D-namoD1aschinen und Elektromotoren unmittelbar von der zulässigen Erwärmung derselben abhängt. Der Materialaufwand wird umso kleiner, je geringer die Wärmeentwicklung in solchen Apparaten oder je besser die Kühlung derselben ist. Bei Dynamoankern, sowie auch bei sehr grossen Wechselstrom- trusfot'atoren, hat man daher, um Material zu ersparen, zur Kühlung durch mechanische Ventilation gegriffen.
Für kleinere l'ransformatoreu und Erregerspulen jedoch stellte sich diese Methode bisher zu theuer. Derselbe Zweck ! ässt sich aber nun auch durch eine wesentliche Vergrösserung der abkühlenden Oberfläche ohne künstliche Ventilation erreichen. Eine solche

FRANZ PICHLER? WHEAT (STEIERMARK). Cooling device for transformers and exciter batteries.
It is known that the cost of materials for AC and three-phase transformers, as well as for the excitation coils on D-namoD1maschinen and electric motors, depends directly on the permissible heating of the same. The cost of materials becomes smaller, the lower the heat development in such apparatus or the better the cooling of the same. With dynamo armatures, as well as with very large alternating current trusphot'ators, one has therefore resorted to mechanical ventilation to save material.
For smaller transformers and excitation coils, however, this method has so far been too expensive. Same purpose! However, it can now also be achieved by significantly increasing the cooling surface without artificial ventilation. Such

Bend or force ptatten open on the inner side in such a way that they enclose the latter between the coil and the core and conduct the heat generated in the core to the outside without it having to penetrate the coil.
