Abstract
A power converter enclosure, intended in particular to equip a rail vehicle traction system including power electronic modules comprising one or more power semiconductor components mounted on a substrate, includes a base including a bottom panel with double walls having an inside wall on the side toward the interior of the enclosure in contact with at least one substrate supporting a power component. The bottom panel is extended by at least two lateral panels with double walls whose outside walls are cooled by cooling fins. The two walls of the bottom panel delimit a hollow volume partly filled with a cooling liquid and containing a thermally conductive permeable material providing a thermal bridge between the two walls.
