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 vascular cooled capacitor assembly includes a plurality of capacitors having respective first and second leads, first and second busbars disposed in electrical contact with the first and second leads, an encapsulant enveloping the capacitors and a respective major portion of each of the first and second busbars, and a network of channels enveloped within the encapsulant and formed by deflagration of a sacrificial material. The network has at least one network inlet and at least one network outlet, each of which is configured for sealable engagement with a cooling fluid system. A branch of each channel is positioned inside a central axial passage of a capacitor, around an outer periphery of a capacitor, and/or between two capacitors. A housing may enclose the capacitors, the channels and major portions of the first and second busbars.

Abstract: An engine block assembly includes a head structure assembly, and a cylinder structure assembly. A plurality of fasteners interconnect the head structure assembly and the cylinder structure assembly. An outer shell encapsulates and supports both the head structure assembly and the cylinder structure assembly. The outer shell is a unitary polymer structure that is simultaneously over-molded onto the head structure assembly and the cylinder structure assembly. The head structure assembly and the cylinder structure assembly are constructed of components that are designed to carry the operational loads of the engine with minimal weight. The outer shell provides additional structural integrity, and provides fluid passages for lubrication and cooling, as well as support for other engine components.

Abstract: A cylinder liner assembly includes an inner wear cylinder, a shell disposed radially outside of an outer surface of the inner wear cylinder, and a central layer disposed between the inner wear cylinder and the shell. The inner wear cylinder is a metal or ceramic, the central layer is a porous material, and the shell is a fiber reinforced polymer. The cylinder liner assembly may include a coolant passage disposed adjacent to the outer surface of the inner wear cylinder, between the inner wear cylinder and the shell. The coolant passage is operable to circulate a coolant therethrough for cooling the inner wear cylinder.

Abstract: A rechargeable energy storage system (RESS) includes battery cells, each having a respective gas vent. The RESS also includes a cell support assembly with thermal runaway mitigation and has a cell holder for supporting the battery cells. The cell holder defines apertures arranged in rows and each aperture fluidly communicates with one cell vent. The assembly also includes multiple thermal-barrier strips adhered to the holder. Each thermal-barrier strip extends parallel to a respective aperture row to thermally insulate each corresponding cell from gases expelled by neighboring cells during a thermal runaway. The assembly additionally includes multiple potting elements. Each potting element is arranged in one of the apertures between a respective cell and a corresponding thermal-barrier strip to thereby adhere to the cell and to the corresponding thermal-barrier strip and maintain position of the cell on the holder. A motor vehicle may employ such a RESS.
