The invention belongs to the field of
electric power cabinets, and particularly relates to an energy-saving heat dissipation type high-
low voltage power cabinet which comprises a bottom plate. The upper surface of the bottom plate is fixedly connected with a cabinet body, the front face of the cabinet body is movably connected with a
front cover plate, and the upper surface of the cabinet body is fixedly connected with a sunshade roof. According to the energy-saving heat dissipation type high-
low voltage power cabinet, an arc-shaped plate is arranged, when external
airflow passes through, the arc-shaped plate guides
cold air at the bottom upwards, according to the Bernoulli principle, the baffle plate is opened under the
pressure difference effect, the density of the
cold air is larger than that of hot air, the
cold air naturally sinks, the external
airflow pushes the cold air to flow out of the rectangular grooves; under the action of the inclined plate, the cold air rises, the cold air absorbs heat and expands in the equipment, the hot air naturally rises and flows out from the bottoms of the cooling fins, heat in the equipment is taken out accordingly, the temperature in the equipment is controlled through flowing of air inside and outside the
electric power cabinet, and the problem that the temperature in a traditional
electric power cabinet is prone to being accumulated and rising is solved.
