Patent attributes
A vehicle power module assembly is provided. The assembly may include a first frame, a second frame, and power stages. The first frame may define a first pair of coolant cavities. The second frame may define a second pair of coolant cavities in communication with the first pair of cavities to define a serial coolant path. Each of the frames may house one of the power stages disposed between the respective pairs of cavities such that coolant flowing through the cavities is in thermal communication with the power stages. The assembly may further include a pair of endplates, one of which defines a channel to divert coolant from a last of the pair of coolant cavities to the outlet cutouts in substantial registration with one another. Each of the first frame and second frame may further define a pass-through fluidly connecting the pair of coolant cavities.
