  • Patent number: 9647510
    Abstract: A cooling jacket (14) for cooling an electric motor, in particular a stator (23), wherein a first spiral line (16) for transporting a coolant is formed at least partially on the cooling jacket (14). The aim of the invention is to provide a cooling system that is optimized in terms of mounting space and ensures axially equalized cooling. This aim is achieved in that a second spiral line (17) for transporting coolant is formed at least partially, and in that based on a common spiral axis R, both spiral lines (16, 17) form an axially integrated double spiral, wherein the first spiral line (16) is an inflow line and the second spiral line (17) is a return flow line. The invention further relates to a deflection unit (12) for the return into the second line (17), which substantially prevents the static pressure from dropping.
