Frequency converter heat dissipation cabinet

The utility model belongs to the technical field of frequency converter heat radiation, and especially relates to a frequency converter heat radiation cabinet. The temperature in the cabinet and the frequency converter accident rate are greatly reduced, and the production efficiency is improved. Comprising a cabinet body; the cabinet body is divided into an upper-layer heat dissipation area and a lower-layer cold source exchange area. A heat exchange tube loop is arranged in the cabinet body and comprises a heat exchange tube part A mounted in the exchange area, a heat exchanger part B mounted in the heat dissipation area, and a circulating air pump communicated with the heat exchange tube part A and the heat exchange tube part B; the frequency converter is installed in the heat dissipation area. An industrial circulating cold water pipe is arranged at the bottom of the lower-layer cold source exchange area, an air blower is installed below the cold water pipe and on the breathable bottom plate, and the heat
