Heat dissipation device for intelligent frequency converter

The utility model provides a heat dissipation device for an intelligent frequency converter, which comprises a frequency converter body, the top of the frequency converter body is fixedly connected with a fixed box, the two sides of the inner cavity of the fixed box are provided with fans, and the right side of the inner cavity of the fixed box is provided with a motor; according to the frequency converter, the probe temperature sensor and the PLC are arranged and used for detecting air in the frequency converter body, when the air in the frequency converter body is higher than a preset value of the PLC, the PLC starts the motor, the motor is matched with the rotating column, the driving wheel and the driven wheel to drive the two fans to rotate, and therefore the air circulation speed is increased, and the frequency conversion efficiency is improved. The problems that the temperature of the frequency converter needs to be noticed all the time due to the fact that the heat dissipation device needs to be start
