Photovoltaic inverter power cabinet

The utility model provides a photovoltaic inverter power cabinet, which comprises a cabinet body. A power module zone and a heat radiation structure for heat radiation of the power module zone are arranged inside the cabinet body. The power module zone comprises a plurality of IGBT power modules. The IGBT power modules are arranged on one side in the cabinet body from top to bottom in a parallel way. The heat radiation structure comprises heat radiation channels. The heat radiation channels include an air inlet zone, an air channel zone and an air outlet zone. The air inlet zone comprises a plurality of air inlets which are arranged on the cabinet body. The position of each air inlet on the cabinet body is respectively corresponding to the position of each IGBT power module. The other side of the cabinet body forms the air channel zone. The air outlet zone comprises air outlets arranged on the cabinet body. The air outlets are arranged on the air channel zone tail end far away from the power module zone. The power cabinet has a simple structure and good heat radiation effects.
