A vehicle electronic control unit water block is provided. The vehicle electronic control unit water block comprises a mounting plate, cooling plate, at least one heat sink, at least one heat sink fin set, and at least one lift plate. The mounting plate and cooling plate define a cooling chamber therein having a first, second and third flow channel. The cooling liquid flows through the first and second flow channels having the at least one lift plate and at least one heat sink therein with a generally minimal and even liquid flow resistance distribution. The at least one lift plate corresponds to an elevated position of the at least one heat sink, such that the volume of cooling liquid flow is even over the lift plates and the thickness of the heat sink is minimized.
