Abstract:
An apparatus for electrically interconnecting, thermally cooling and mechanically supporting a plurality of electrical components that require cooling, comprising:a circuit board mounting the plurality of components, wherein the circuit board is in electrical communication with each component; and a fluid-cooled heatsink in thermal communication with the plurality of components; wherein the plurality of electrical components that require cooling, and all other components on the circuit board, are on the same side of the circuit board so as to allow wave soldering of the circuit board; wherein the heatsink defines a first fluid-filled cavity and a second fluid-filled cavity that are separated by a common wall; wherein the heatsink is configured such that fluids in the second cavity flow in a direction along the common wall that is opposite of the direction of fluids flowing in the first cavity; and wherein the heatsink is configured such that each of the plurality of electrical components can be located along ends of the wall.
