Abstract:
A cooling crescent for a hybrid module includes a first half section and a second half section. The first half section has a radially outer inlet orifice and a plurality of circumferentially disposed radially inner outlet orifices. The second half section is sealed to the first half section to form a narrow channel hydraulically connected to the radially outer inlet orifice, and a circumferentially extending channel hydraulically connected to the narrow channel and the plurality of circumferentially disposed radially inner outlet orifices. In some example embodiments, the first half section or the second half section comprises a plurality of axially extending tabs with respective orifices for fixing the cooling crescent to a housing of the hybrid module. In an embodiment, the plurality of axially extending tabs are configured to be adjustable to vary a respective height of the tabs to accommodate for e-motor stators of varying sizes.
