Power inverter for a vehicle

摘要

A power inverter includes a plurality of power modules stacked in an array. A plurality of coolant chambers are interleaved with the modules. Each of the chambers includes an inlet and an outlet interconnected by a coolant path configured to circulate coolant within the chamber. Fins project into the coolant path and are configured to alter shape based on a temperature of the coolant to alter a turbulence associated with the coolant.

1. A power inverter comprising:
power modules each including opposing major sides that each define a pocket recessed therein, and being arranged in a stack such that pockets adjacent to each other cooperate to form coolant chambers interleaved with the modules; and flow guide assemblies each disposed within one of the coolant chambers and including fins configured to alter shape based on a temperature of the coolant to alter a turbulence associated with the coolant.
