Abstract
An electric compressor includes a compression mechanism, an electric motor and a housing. The compression mechanism draws, compresses and discharges refrigerant gas. The electric motor drives the compression mechanism. The housing accommodates the compression mechanism and the electric motor. A heat sink extends from the housing. An inverter is located in the housing. The inverter powers the electric motor. A heat sink cools the inverter. The heat sink is cooled by refrigerant gas. The heat generated by the inverter is therefore effectively reduced.
