The utility model discloses a frequency converter protection device with dustproof and cooling functions, which comprises a base, stand columns are vertically mounted at four corners above the base, three groups of sealing plates are vertically inserted between the stand columns at the left side, the right side and the rear side above the base, and a mounting plate is arranged at the tops of the stand columns above the base. The four corners of the mounting plate can move up and down along the stand columns in a reciprocating mode, a mounting groove is formed in the middle of the top face of the mounting plate, a fan is arranged in the mounting groove, and heat dissipation plates are arranged on the inner sides of the two oppositely-arranged sealing plates. The device has the advantages that active heat dissipation and passive heat dissipation are combined through the heat dissipation plate and the fan, the heat dissipation effect on the frequency converter in the device is better, and meanwhile disassembly,
