Cooling spray tube arrangement above stator of electrical machine

A cooling arrangement comprising:

• a machine housing;
• a stator mounted in the machine housing rotationally symmetrically in a radial direction R around at least one rotor, wherein the stator comprises a stator winding, such that the stator winding extends in an axial direction between opposite ends;
• a first winding head and a second winding head are arranged in the opposite ends of the stator winding;
• a centering plate which encloses the stator radially at a first axial end and which also extends axially, radially a distance above the stator, forming a centering plate section;
• at least one spray tube positioned in the radial position above the stator and fixed to the stator, wherein the at least one spray tube extends in an axial direction over a full length of the stator and is configured to convey a fluid;
• an integrated sleeve designed to convey fluid, the integrated sleeve attached to the centering plate and aligned in the axial direction with the at least one spray tube, so that coolant can flow into the at least one spray tube in the axial direction from the sleeve;
• and
• a supply duct wherein the at least one spray tube is connected to the supply duct and configured for conveying the fluid;
• wherein the at least one spray tube defines at least two outlet openings, the at least two outlet openings including a first outlet opening positioned in an area above the first winding head and a second outlet opening positioned in an area above the second winding head, so that a coolant flowing through the at least one spray tube flows at least in part down onto the first winding head and the second winding head.
