Abstract

Es wird eine Drosselspule mit spiralförmiger, in Isoliermaterial eingebetteter Wicklung vorgeschlagen, wobei mindestens eine Stirnfläche (9,10) der Drosselspule (1) derart ausgebildet ist, daß hierüber die in der Wicklung (3,4,5) entstehende Stromwärme mittels thermischer Kontaktierung an mindestens einen Flüssigkeitskühlkörper (18,19) abgegeben werden kann. A choke coil with a spiral-shaped winding embedded in insulating material is proposed, at least one end face (9, 10) of the choke coil (1) being designed such that the current heat generated in the winding (3, 4, 5) is applied by means of thermal contacting at least one liquid heat sink (18, 19) can be dispensed.
