Abstract: A heatsink or heat exchanger for one or more power modules of an inverter or a converter comprises a coolant flow channel, comprised of a plurality of coolant flow channel portions that form a switchback or serpentine flow path, and that is adapted to circulate coolant inside the heat exchanger or heatsink. One or more vents can be provided inside the heat exchanger or heatsink to pass air from one coolant flow channel portion to an adjacent coolant flow channel portion.

Abstract: A heat sink for power modules can be incorporated into a power module of a machine. In embodiments, an alloy is extruded to form a body with a plurality of divider webs integral thereto and defining a plurality of longitudinal passage segments inside the body. The body is machined to remove alternating end portions of the divider webs to define a fitting end turn area and a return end turn area disposed in opposing relationship with each other, thereby forming a serpentine fluid passage. A fitting end cap is welded to the body. A fluid inlet and a fluid outlet of the fitting end cap are respectively in fluid communication with a passage inlet and a passage outlet of the serpentine fluid passage.

Abstract: The disclosure relates to packaging of an energy storage module containing a plurality of storage cells for use in mobile and stationary power generation. The storage cells are pressed into a block of thermally conductive material in order to manage the temperature of the cells. The storage cells are secured between a clamping plate and a chassis. The resulting package is suitable for use in heavy duty applications.

Abstract: A power converter assembly includes a housing and at least one transistor module. The housing has a liquid cooled heat transfer surface. The at least one transistor module is mounted directly to the liquid cooled heat transfer surface and positioned at least partially within the housing.

Abstract: Assembling a power converter for a multiple phase electric drive propulsion system in a machine includes arranging a plurality of rectangular capacitor units of a capacitor subassembly for conditioning electrical power in the power converter in a first packaging arrangement. In the first packaging arrangement, major capacitor axes of each one of the capacitor units are co-linear with one another and minor capacitor axes of each one of the capacitor units are oriented parallel but not co-linear with one another. Assembling the power converter further includes arranging a plurality of IGBT modules of a transistor subassembly for power switching in the power converter in a second packaging arrangement. In the second packaging arrangement major module axes of each one of the IGBT modules are oriented parallel but not co-linear with one another and minor module axes of each one of the IGBT modules are co-linear with one another.
