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.
