Abstract
A cooling arrangement for an electric machine includes a machine housing and a stator mounted rotationally symmetrically in a radial direction around at least one rotor in the machine housing. The stator has a stator winding extending axially between opposite ends in which are located a first winding head and a second winding head. At least one spray tube configured to convey fluid is fixed radially above the stator and extends axially over the full length of the stator. The spray tube is connected to a supply duct for delivery of fluid, where the spray tube has at least two outlet openings that include an outlet opening in an area above the first winding head and in an area above the second winding head, so that the coolant flowing through can flow down at least in part onto the first winding head and the second winding head.
