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 modular inverter arrangement comprising one or more cages of a cage assembly, including at least a first cage of the cage assembly. Each of the one or more cages can be in the form of a cuboid, and each of the one or more cages can be adapted to accommodate therein respective sets of one or more power modules. The modular inverter arrangement can also be comprised of a heatsink extending transversely through each of the one or more cages, from a first end of the cage assembly to a second end of the cage assembly opposite the first end.
