Abstract: This application discloses a power distribution cabinet which includes a cabinet body, a first air duct assembly, and a second air duct assembly. The first air duct assembly is disposed outside the cabinet body, and the first air duct assembly is disposed on the first side wall of the cabinet body. A projection of the first air duct assembly on the first side wall covers the first air vent and the second air vent. A first circulation space is formed between the first air duct assembly and the first side wall. The first circulation space communicates with an internal space of the cabinet body through the first air vent and the second air vent. The second air duct assembly is disposed inside the cabinet body, and the second air duct assembly forms a second circulation space. The second circulation space communicates with the first air vent.
