Abstract: A heat exchanger includes a pair of opposed, spaced apart heat exchanger plates defining a heat exchanger volume therebetween having an inlet and opposed outlet. A plurality of heat exchanger ribs are included within the heat exchanger volume. Each rib defines a rib body spanning the heat exchanger volume. Each rib body includes a plurality of slits therethrough to define a flow path through the heat exchanger ribs from the inlet to the outlet of the heat exchanger volume. The ribs and slits can be formed using ultrasonic additive manufacturing (UAM), for example.

Abstract: An electrical machine includes a winding core with a plurality of end slots. A winding is seated in the end slots with end windings where the winding crosses from end slot to end slot. A slot insulator is seated in two of the end slots. The slot insulator includes a first slot liner seated in a first one of the two end slots with a winding slot defined therethrough in an axial direction. A second slot liner is seated in a second one of the two end slots with a winding slot defined therethrough in the axial direction, wherein the second slot liner is spaced apart in a lateral direction relative to the axial direction from the first slot liner by a gap. The slot insulator includes a span portion bridging across the gap to connect the first and second slot liners.
