Coolant flow distribution using coating materials

Abstract

Electronic devices are disclosed including hydrophobic or oleophobic coatings that control coolant flow therein or thereon. In at least one embodiment, a power inverter cold plate is provided including coolant inlet, a coolant outlet, a coolant flow spreading region, a coolant flow collection region, and a coolant heat-transfer region disposed therebetween; and one or more layers of a hydrophobic or oleophobic coating configured to control a flow of coolant in the cold plate. A method may include applying one or more layers of a hydrophobic or oleophobic coating to a power inverter cold plate to control a flow of coolant in the cold plate, the one or more layers being applied to one or more of a coolant flow spreading region, a coolant flow collection region, or a coolant heat-transfer region disposed therebetween. The layers may define coolant flow paths, eliminate recirculation zones, and/or prevent coolant leak paths.
