Abstract
An inverter assembly for a motor vehicle includes a housing with an inlet end for receiving a flow of coolant and an outlet end for discharging the flow of coolant. The assembly further includes a first plurality of power transistors conducting and switching an electrical current and generating a first amount of heat. The assembly further includes a second plurality of power transistors conducting and switching the electrical current and generating a second amount of heat that is less than the first amount of heat. A heat sink includes a plate with a first section adjacent to the first plurality of power transistors and a second section adjacent to the second plurality of power transistors. The heat sink further includes a first plurality of fins for drawing the first amount of heat from the first section and a guide vane directing the flow of coolant toward the first plurality of fins.
