An electric machine includes a stator having an outer circumference. Spaced apart first walls are arranged about the outer circumference and provide generally parallel first channels. A second wall adjoins the first wall and is arranged about the outer circumference providing a second channel in fluid communication with the first channels, thus, providing a tortuous fluid flow path about the circumference. The first and second channels have an inner surface. A structure is provided within at least one of the first and second channels. The structure has an outer surface spaced radially outward from the inner surface and at least partially defines the tortuous flow path between the outer and inner surfaces. The stator includes an end turn. An end cap extends axially and radially outward from the stator and provides an enclosure about the end turn in fluid communication with the exit associated with the flow path.
