Abstract

Bei einem gekühlten Ringträger (2) - bestehend aus einem Ringträger (2) und einem aus Blech geformten Kühlkanal (4) - soll die Herstellbarkeit des Blechkühlkanals (4) verbessert werden, da die Herstellung eines einteiligen Blechkühlkanals (4) aufwendig und teuer ist.
Hierzu wird der Blechkühlkanal (4) aus zwei Blechteilen, insbesondere zwei Blechhalbschalen (5,6) gebildet, die vorzugsweise miteinander verschweißt werden.
