Among various factors influencing the reliability of the frequency converter, heat dissipation is crucial, and the temperature of a high-power semiconductor device is increased due to heat generated during operation, and if no proper heat dissipation measures are taken away in time, the temperature of the device may exceed the maximum junction temperature allowed by the device, so that the performance of the device is deteriorated or even damaged. Therefore, a frequency converter cabinet capable of providing a good heat dissipation environment for the frequency converter is needed.
