Abstract: A power module is provided and includes first stack, second stack, and third stacks of layers, a heat pipe, and at least one cold plate or heat sink. The third stack of layers is disposed between the first and second stacks of layers and includes a first semiconductor die, a second semiconductor die and a center spacer layer disposed between the first semiconductor die and the second semiconductor die. The heat pipe extends at least partially into the center spacer layer. The at least one cold plate or heat sink receives thermal energy from the first stack of layers and the second stack of layers. The first stack of layers, the second stack of layers, the third stack of layers, the heat pipe and the at least one cold plate or heat sink facilitate dual sided cooling of each of the first semiconductor die and the second semiconductor die.

Abstract: Presented are electronic power module assemblies with direct-cooling vapor chamber systems, methods for making/using such power module assemblies, and vehicles equipped with such power module assemblies. A power module assembly includes an outer housing with an internal coolant chamber that circulates therethrough a coolant fluid. A power semiconductor switching device is mounted to the module's housing, separated from the coolant chamber and isolated from the coolant fluid. The power device selectively modifies electric current transmitted between a power source and an electrical load. A two-phase, heat-spreading vapor chamber device includes an outer casing with a casing segment that is mounted to the module housing, fluidly sealed to the internal coolant chamber and exposed to the coolant fluid. Another casing segment includes an inboard-facing casing surface that is mounted to an outboard-facing surface of the power device, and an outboard-facing casing surface mounted to an inboard-facing surface of the power device.

Abstract: Presented are electrical conductor assemblies with vascular cooling systems, methods for making/using such assemblies, and vehicles equipped with such assemblies for transmitting power and coolant between electric devices. An electrical conductor assembly includes an outer sheath, an electrical conductor extending through the sheath, a coolant channel defined through the sheath, and an optional cable jacket encasing the electrical conductor. The outer sheath has a tubular body formed from an electrically insulating material. The electrical conductor has a solid cable body located within a conductor duct extending through the sheath. The coolant channel, which is coaxial with and thermally connected to the cable body, passes therethrough coolant fluid that cools the electrical conductor. The cable jacket may be formed from an electrically insulating material having a thermal conductivity and melting point higher than that of the sheath. The conductor assembly may include multiple electrical conductors circumferentially spaced around the coolant channel.

Abstract: A method of fabricating a mold for producing a part includes applying a network of sacrificial components onto a first surface of a mold base, wherein the sacrificial components are made of a sacrificial material, covering the network of sacrificial components and the first surface with a layer of a covering material, and removing the sacrificial material to produce a network of channels within the layer of covering material. The network of sacrificial components may be formed by additive manufacturing or by mechanical placement of a preformed network of sacrificial components.

Abstract: Methods for forming composite components with sealed bi-material interfaces include applying a sacrificial material to a surface of a substrate, over-molding the substrate and the sacrificial material with an over-molding material such that the over-molding material covers at least a portion of the sacrificial material and at least one surface of the substrate, removing the sacrificial material by deflagration to form a composite component with a channel between the substrate and the over-molding material, introducing an uncured sealant into the channel, and curing the sealant to form a sealed composite component. The method can further include removing a portion of the sealant prior to the sealant fully curing. The sealed composite component can include a passage, encircled by the channel, extending between the substrate and the over-molding material. The substrate can be a metal, a polymer, a polymer composite, a ceramic, or a continuous fiber composite material.

Abstract: An electric machine is described, and includes a rotor that is rotatably disposed in a stator. The rotor includes a rotatable shaft that is disposed on a longitudinal axis, and a plurality of laminations that are disposed on the rotatable shaft. The plurality of laminations are arranged on the rotatable shaft to form a plurality of axially-disposed cavities, wherein each of the cavities is defined by a surface. A coating is disposed on the surfaces of the cavities, and a curable filler material is introduced into each of the cavities. The curable filler material adheres to the plurality of laminations via the coating.

Abstract: A method of forming at least one channel within a substrate includes coupling a fitting to a mold, and securing together the fitting and an insert via threads. A system includes a mold configured to form the substrate. The method also includes inserting a component into an opening of the fitting. Part of the component is disposed outside of the opening of the fitting, and the component is utilized to define the at least one channel within the substrate. The method further includes molding at least one material to the component and the insert to form the substrate. Furthermore, the method includes removing the fitting from the insert while the insert remains molded to the substrate.

Abstract: Continuous fiber tow structures are used to form lattice reinforcing bodies to be embedded in a molded polymer matrix. The lattice structures are formed and shaped to reinforce a portion of a predetermined three-dimensional article. Optionally, some or all of the tow members of the structure may be formed with internal vascular passages for passage of a heat transfer fluid through the structure in the function of the molded polymer article. A liquid polymer is molded around the lattice structure, fully embedding the structure. The liquid polymer which may contain short-reinforcing fibers, is then solidified to form the composite reinforced polymer article. And connections may be made to the composite article for the flow of the fluid through vascular passages in the lattice structure within the article.
