Electric cabinet with good heat dissipation function

The utility model discloses an electric cabinet with a good heat dissipation function, which relates to the technical field of power distribution cabinets and comprises a shell, an outer shell and a lighting assembly used for night operation. The alarm mechanism is arranged at the top of the shell and is mainly used for monitoring the temperature in the electric cabinet, and when the temperature exceeds the standard, the alarm mechanism sends out alarm information; the heat dissipation mechanism is arranged outside the shell and mainly comprises an exhaust assembly and a cooling assembly, the exhaust assembly is mainly used for exhausting hot air in the electric cabinet to the outside, and the cooling assembly rapidly reduces the temperature in the electric cabinet in a water cooling mode; and the solar mechanism is arranged at the top of the shell. According to the electric cabinet with the good heat dissipation function, the temperature in the shell can be rapidly reduced to a safety value under the combine
