Abstract: A vehicular electronic control unit (ECU) includes a printed circuit board (PCB) and a housing that accommodates the PCB. The PCB includes an electronic component that, when electrically operated, generates heat within the housing. Heat dissipating fins extend along an exterior side of the housing. Heat generated within the housing is dissipated via the heat dissipating fins. A shroud extends along the exterior side and covers the plurality of heat dissipating fins. A passageway extends through the shroud. An airflow source is electrically operated to draw air from within a cavity between the shroud and the exterior side of the housing and along and through the passageway and the drawn air flows between the exterior side and the shroud and along and between the heat dissipating fins to dissipate heat from the plurality of heat dissipating fins.

Abstract: A vehicular electronic control unit (ECU) includes a housing that accommodates a printed circuit board (PCB). At least one heat-generating electronic component is disposed on the PCB. The ECU includes a plurality of heat dissipating fins disposed at an exterior side of the housing. The heat dissipating fins are disposed within a fluid chamber at the housing, and heat is dissipated from the heat dissipating fins via coolant that flows within the fluid chamber along and between individual heat dissipating fins of the plurality of heat dissipating fins. An inlet port provides flow of coolant into the fluid chamber, and an outlet port provides flow of coolant out of the fluid chamber. The heat dissipating fins provide a multi-channel flow path for coolant within the fluid chamber between the inlet port and the outlet port.
