Converter for underwater electromechanical device

The utility model discloses an inverter for underwater electromechanical equipments. The utility model comprises an inverter main body, an installation bracket used to fix the inverter main body, and a hollow pressure proof sealed container in cylindrical type with an end bracket which is used to seal up and pack the inverter main body. The utility model is characterized in that the hollow pressure proof sealed container in cylindrical type is packed with insulative heat conductive liquid substances in which an IGBT module is immersed. The insulative heat conductive liquid can conduct heat generating from the IGBT module to the shaft wall of the pressure proof container and then to the outer water which can guarantee that the IGBT module operate regularly to make the inverter work for a long time in the deep oceans.
