Abstract: A heat exchanger for an electrical element is provided. The heat exchanger includes a first plate, a second plate adapted to contact the electrical element and a plurality of heat exchange channels. The plurality of heat exchange is between the first and second plates to enable heat exchange between a fluid flowing in the plurality of heat exchange channels and the electrical element. The heat exchanger further includes a first portion and a second portion. The first portion of the heat exchange channels is in thermal contact with a first of the electrical elements and the second portion of the heat exchange channels is in thermal contact with a second of the electrical elements.
