[0021] The utility model provides an efficient heat dissipation structure of an inverter PCB board. During the operation of the inverter, the main body of the PCB board generates heat. The heat dissipation efficiency is low if the inside of the base is only dissipated by a fan and a heat dissipation port. At this time, two heat conduction plates are first slid into the base along a mounting groove from the outside of the base, and the heat conduction plates are moved close to the main body of the PCB board so that the main body of the PCB board is located between a clamping plate and the heat conduction plates.
