Abstract
An electronics assembly is provided having a housing including walls defining a fluid vessel. One or more thermally conductive heat sink devices extend through one or more openings in the housing and in thermal communication with a liquid coolant. One or more electronics devices are mounted onto a mounting surface of the heat sink devices such that the electronics devices are cooled by the liquid coolant in the fluid vessel.
