Housing having stator and rotor of electric machine, has partition wall that separates primary fluid outlet from fluid inlet such that cooling fluid enters into fluid inlet, passes through fluid path and exits through fluid outlet

摘要

The housing (12) has annular cooling chamber and fluid circulation path which is defined around stator (14) or rotor (16). A fluid inlet (24) and a fluid outlet (26) are in communication with the annular cooling chamber. A partition wall (28) separates the primary fluid outlet from the fluid inlet such that cooling fluid enters into the fluid inlet, passes through the fluid path and exits through the fluid outlet.
