Photovoltaic power generation is applied outdoors, and mainly adopts outdoor distribution boxes for power distribution. The main body of the existing photovoltaic power generation distribution cabinet mainly dissipates heat to the inside through the heat dissipation holes opened on the outside of the shell, and the heat dissipation effect is not good. When the weather temperature is high, due to the slow air flow speed and the long-term direct sunlight on the top of the distribution cabinet body, the interior of the distribution cabinet body is prone to heat accumulation, which can easily cause failures of the electronic components inside the distribution cabinet body.
