Choke coil with spiral-shaped winding

摘要

The choke coil (1) includes a spiral-shaped winding (3,5) which is embedded in insulating material. At least one outer face (9) of the choke coil is formed in such a way that the current heat arising in the winding can be dissipated by thermal contacting to at least one liquid heat sink. In one embodiment the outer face is formed in such a way that the metallic electrical conductor (3) of the winding has direct thermal contact with at least one liquid heat sink.
