Abstract:
1. A horizontal type electric compressor comprising: a compressor configured to compress a refrigerant, the compressor having a plurality of passage ports delivering the refrigerant; an electric motor configured to drive the compressor, the electric motor having a plurality of stators and an accommodation chamber accommodating the plurality of stators, each of the stators comprising a coil wound around a ferromagnetic core; a partition wall formed in a housing of the electric compressor, the partition wall separating the compressor and the accommodation chamber of the electric motor; a plurality of refrigerant introducing/discharging passages formed at the partition wall, wherein the refrigerant introducing/discharging passages are located in a circumferential direction of the accommodation chamber, thereby the refrigerant being introduced into and discharged from stators end in the electric motor through the refrigerant introducing/discharging passages; and a refrigerant circulation passage formed between the passage ports and the partition wall, thereby introducing the refrigerant from the passage ports to the refrigerant circulation passage or introducing the refrigerant from the refrigerant circulation passage to the passage ports, wherein each of the refrigerant introducing/discharging passages comprises a plurality of round holes, wherein a number of the plurality of round holes is greater than a number of passage ports, and wherein a number of refrigerant introducing/discharging passages equals a number of the stators.
