Waterproof frequency converter

The utility model discloses a waterproof frequency converter. The waterproof frequency converter comprises a shell and a steam-water separator, and the steam-water separator comprises an upper transverse baffle and a lower transverse baffle. The upper transverse baffle is equipped with a first spoiler set, and the lower transverse baffle is equipped with a second spoiler set. The vertical plates in the first and second spoiler sets are in staggered arrangement to form the U-shaped roundabout air channels, and a tubular apron board is equipped with an air suction port of which the axial direction is vertical with the vertical plates. According to the utility model, the steam-water separator is arranged at the lower part of an air inlet of the shell of the frequency converter, and the steam-water is intercepted during the contact process of the air with the steam-water and the vertical plates of the spoiler sets, so that the steam-water separation is realized, the steam-water can be prevented from entering the shell of the frequency converter to damage the electric appliance elements, the frequency converter failure rate can be reduced, and the service life of the frequency converter is prolonged.
