Abstract
Electronic devices are disclosed including hydrophobic or oleophobic coatings that control coolant flow therein or thereon. In at least one embodiment, an electric machine is provided including a stator core defining a cavity, windings disposed within the cavity and including end windings protruding from the cavity, and one or more layers of an oleophobic coating overlying the end windings and configured to control a flow of coolant over the end windings. A method may include applying one or more layers of a oleophobic coating to end windings of an electric machine stator such that the one or more layers control a flow of coolant over the end windings. The one or more layers may define coolant flow paths, which may direct coolant to areas of the electric machine requiring additional cooling, such as hot spots or neutral points.
