Abstract
A cooling jacket for cooling the stator of an electric machine. The jacket includes a cooling jacket body having a cylindric inner surface defining a cavity for receiving the stator of a motor, axial flow passages in the body for the flow of a coolant, and end caps connected to opposite ends of the body. Coolant flows through an inlet in one of the end caps and is directed through the flow passages along at least one serpentine path to an outlet. Each flow passage has a cross sectional shape defined entirely by three or more substantially linear sides.
