In this paper, we propose an optimal heat dissipation design for an water-cooled MCU for an electric two-wheeled vehicle. Changed parts were limited to heat sink parts and coolant. Cooling channel width and length, cooling flow type, heatsink thickness, coolant inlet flow and coolant inlet temperature were selected as detailed modifiers, and the effect of each factor was analyzed by analyzing the temperature to reach saturation temperature of the MOSFET device of each detail modifier. Although all the change factors affected the temperature to reach saturation temperature, the factor having the greatest influence was identified as the temperature of coolant. However, since the cooling water inflow temperature is related to the cooling system such as the vehicle\'s radiator and EWP, the cooling system cost can be reduced only by requiring the system to have an appropriate level of cooling water inflow temperature |
