  • Patent number: 12221965
    Abstract: An electric compressor, wherein an oil separator is formed on an inner wall on the discharge path, and wherein the oil separator is formed in a concavo-convex shape along a rotation direction of the refrigerant on the discharge path. In the compressor, the farther it is from a discharge hole along a rotation direction of the refrigerant, the greater the depth of a first groove portion formed in an oil separator is. As a result, the oil contained in the refrigerant is separated.

  • Publication number: 20250010692
    Abstract: An electric compressor and a heat exchanger module including the same. The heat exchanger module includes heat exchanger components, a manifold, a bracket mounting the heat exchanger components and the manifold, and an electric compressor. Further, the heat exchanger module may perform cooling through heat exchange by separating an inverter module coupled to a compressor and attaching the separated inverter module to a chiller in which a working fluid at a low temperature flows.

  • Patent number: 11994119
    Abstract: A compressor including: a casing; a rotary shaft rotatably mounted in the casing; a compression mechanism configured to compress a refrigerant by operating in conjunction with the rotary shaft; a thrust plate configured to support an end surface of the rotary shaft; a chamber configured to accommodate the thrust plate; and a slit configured to guide oil to the chamber, in which a part of the slit is formed to face a contact portion between the rotary shaft and the thrust plate, such that it is possible to supply the oil between the rotary shaft and the thrust plate, thereby preventing damage to the thrust plate for supporting the rotary shaft. In addition, an inner diameter of the chamber gradually increases, and the chamber extends to an end surface of a cylinder block, such that the cylinder block may be easily extracted from a mold.
