Abstract
A cooling system for a power electronics unit includes a heatsink arrangement and multiple blocks. The heatsink arrangement includes first and second heatsinks to receive a coolant flow. The first heatsink includes first openings and the second heatsink includes second openings. Blocks are positioned between the heatsinks. Each block defines a flow regulation feature such that coolant flows between the first and second openings is selectively routed and restricted. One block is swappable with another block to interchange locations of flow regulation features to switch the cooling system between first and second configurations. In the first configuration, the heatsinks are fluidly connected to each other to receive the coolant flow according to a series flow. In the second configuration, the heatsinks are fluidly connected to each other to receive the coolant flow according to a parallel flow.
