A cooling apparatus is provided for an AC generator, particularly for a transverse-flow generator having a stator with at least one armature winding, as well as a rotor disposed opposite the armature winding. Collector rings are secured to a carrier disk attached to a rotor shaft. The collector rings have a plurality of polarized magnets and magnetizable collector elements in alternating sequence disposed therein. At least one cooling channel through which a coolant can flow is provided in the vicinity of the carrier disk. The cooling channel is separated from the carrier disk only by a channel cover which has a minimal thickness and by the air gap between the rotor and the stator.

[ We claim:] [1.] In a cooling apparatus for an AC generator, said AC generator comprising a stator with at least one armature winding, a rotor having a shaft and a periphery, said rotor disposed opposite the armature winding, collector rings having a plurality of polarized magnets and magnetizable collector elements in an alternating sequence, said rings disposed at the periphery of the rotor, a carrier disk secured on the rotor shaft and co-axial therewith, said collector rings being secured to said carrier disk, and cooling devices connected to the stator,the improvement wherein the cooling devices define at least one cooling channel disposed in the vicinity of the carrier disk in the stator and through which a coolant flows, said cooling channel being separated from the carrier disk by a channel cover of minimal thickness and by an air gap located between the rotor and the stator, the carrier disk and regions of the stator that are opposite to the region of the cooling channel comprise meshing complementary teeth having surface areas running essentially parallel to one another and being separated from one another by an air gap.
