The invention relates to a cooling jacket (14) for cooling an electric motor, in particular a stator (23), wherein a first spiraled 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. Said aim is achieved in that a second spiraled line (17) for transporting coolant is formed at least partially, and in that based on a common spiral axis R, both spiraled lines (16, 17) form an axially integrated double spiral, wherein the first spiraled line (16) is an inflow line and the second spiraled line (17) is a backflow 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. |
