Connection of cooling circuit portions for an assembly of two housings

An assembly comprising two housings, a first housing comprising a first cooling circuit portion for cooling a first heat load integrated into the first housing and a second housing comprising a second cooling circuit portion for cooling a second heat load integrated into the second housing, said cooling circuit portions being configured to form a cooling circuit with a fluid, the first housing having a first opening, the second housing having a second opening, each housing comprising a flat face defining an interface of said cooling circuit, said cooling circuit portions being configured to be fluidically connected through plane-plane contact between said flat faces, the first opening being arranged on the left side of the assembly, the second opening being arranged on the right side of the assembly, wherein one of said openings forms an inlet of the second cooling circuit portion and the other of said openings forms an outlet of the first cooling circuit portion, wherein a recess extends from at least one of the openings said recess arranged in the corresponding flat face and extending from said at least one of the openings so that the periphery of said recess also encompasses the other of said openings when the flat faces are in plane-plane contact, thereby providing fluidic connection of the two cooling circuit portions, including when the inlet and the outlet are misaligned;

• wherein the first heat load comprises an inverter and the second heat load comprises an electric motor.
