The frequency converter comprises a frame assembly, a heat dissipation assembly, a dustproof mechanism, a buffer assembly and an exhaust window, the heat dissipation assembly is installed in the left side of the frame assembly, the exhaust window is formed in the right side of the frame assembly, and the dustproof mechanism is installed outside the exhaust window. And a buffer assembly is arranged below the bottom of the dustproof mechanism. According to the efficient heat dissipation frequency converter, the arranged cover plate is closed in a downward sliding mode through the sliding block, dust can be effectively prevented from entering the device body, the situation that faults are caused by static electricity generated by the dust can be effectively eradicated, internal hot air is exhausted out of the exhaust window through the heat dissipation fan, air is fed through the air inlet window, and repeated circulation is achieved, so that the heat dissipation effect is improved, and the service life of the f
