Abstract:
1. An electric machine module comprising: a module housing including a sleeve member and at least one end cap, an inner wall of the module housing at least partially defining a machine cavity; a cooling jacket positioned within a portion of the sleeve member; and at least one partition positioned substantially axially extending across at least a majority of an axial length of the sleeve member within the cooling jacket and dimensioned to substantially seal a first coolant cavity region of the cooling jacket from a second coolant cavity region of the cooling jacket, the first coolant cavity region extending around a majority of a circumference of the cooling jacket and coupled upstream of the machine cavity to receive a pressurized coolant flow prior to the machine cavity, the first coolant cavity region being in fluid communication with the machine cavity to enable coolant passage into the machine cavity; and the second coolant cavity region fluidly coupled downstream of the machine cavity and the partition.
