Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A vehicle power module assembly comprising: a frame defining a cavity, an inlet, an outlet, and a second cavity; a second frame defining a second inlet for registration with the inlet, a second outlet for registration with the outlet, a third cavity open to the second cavity, and a fourth cavity open to cavity; and a power stage housed between respective cavities arranged to define a mixed series and parallel coolant flow path. 2. The assembly of claim 1 , wherein each of the frames further defines a primary channel connecting the first and fourth cavities adjacent one another. 3. The assembly of claim 1 , wherein each of the frames further defines a secondary channel connecting the second and third cavities adjacent one another. 4. The assembly of claim 1 further comprising a pair of endplates compressing the frames therebetween, wherein one of the endplates defines a transition channel in communication with the outlets to transfer coolant flow. 5. The assembly of claim 1 further comprising a pair of endplates compressing the frames therebetween, wherein one of the endplates defines an external inlet open to a primary channel of the frames and an external outlet open to a secondary channel of the frames.
