Embodiment 2
[0032] Embodiment 2, with reference to figure 2Specifically, in the solution of this embodiment, a heat dissipation structure for multiple frequency converter groups includes the control cabinet body 2 and multiple groups of frequency converter groups; each of the frequency converter groups moves from bottom to top or Vertically arranged and installed inside the control cabinet body 2 from top to bottom; the second group of frequency converters 3 also includes: heating element power modules 31, radiators 32, copper bars, drive electronic boards 34, fixed sheet metal Part 35 and heat dissipation fan 36; through the integrated design of the heat dissipation air duct and the control cabinet body 2, the heat dissipation between two or more frequency converter groups does not affect each other. It should be noted that the heat dissipation between two or more inverter groups does not affect each other, the volume of the control cabinet body 2 or the volume of the inverter group is ...
