Abstract

A generator housing (10) for holding a stator and a rotor that rotates about a drive shaft, characterized by a plurality of first cooling channel sections (30) traversing the generator housing (10) in the axial direction at least at part of the length thereof, said channel sections being formed from a plurality of axially extending bars (40) with lengths shorter than the length of the first cooling channel sections (30), wherein adjacent bars (40) forming the first cooling channel sections (30) abut opposite axial ends of the first cooling channel sections (30), respectively.
