Control method of heat dissipation system

The invention provides a control method of a heat dissipation system, which is used for cooling a motor controller of the electric vehicle. The heat dissipation system comprises a fluid driving deviceused for driving airflow to flow, the fluid driving device is connected with the bus of the motor controller, the heat dissipation system comprises a first heat dissipation mode, and when the fluid driving device is in communication connection with the motor controller through the bus, the heat dissipation system dissipates heat of the motor controller in the first heat dissipation mode. According to the control method, the real-time temperature of the motor controller can be rapidly, accurately, simply and efficiently obtained, so that the flow velocity of the air flow is controlled, the heat dissipation water tank of the heat dissipation system is rapidly and efficiently cooled, the motor controller is further cooled, and a better heat dissipation effect is obtained. 本发明提供了一种散热系统的控制方法，用于给电动车的电机控制器进行散热，散热系统包括用于驱
