Vehicle Heat Exchanger Fan Motor Transistor Module Cooling System

摘要

The present invention relates to a vehicle heat exchanger fan motor TR module unit cooling device for cooling the TR module unit controlling the rotational speed of the fan motor for cooling fan by convection wind of the cooling fan to increase its cooling efficiency. It is provided with a cooling fin 120 on one side of the case 110 of the built-in TR module unit 100 to be inserted into the fan loudspeaker 23 to exchange heat with the convective wind generated by the fan motor 21. To increase the cooling efficiency.
