Abstract
A cooling jacket surrounding the stator of an electric machine, having an inlet and a plurality of outlets disposed at ends of the cooling jacket, distributed in circumferential direction and configured to create liquid jets exiting the cooling jacket in a radial direction towards end windings at the axial ends of the machine. Coolant liquid flow guiding elements within the cooling jacket are configured so as to create a circumferentially homogeneous or more homogenous axial liquid flow towards the liquid outlets and/or towards the liquid jet devices.
