Definitions

  • the present invention relates to electric compressors equipping a motor vehicle, for example, for the circulation of a refrigerant fluid FR inside a refrigerant circuit FR of the motor vehicle. It relates to such an electric compressor.
  • a motor vehicle is commonly equipped with a refrigerant circuit FR which is provided to change a temperature of an air flow prior to its admission into a passenger compartment of the motor vehicle.
  • the refrigerant circuit FR comprises in particular a compressor for compressing a refrigerant fluid FR which circulates inside the refrigerant circuit FR.
  • the compressor is in particular an electric compressor which comprises a compression mechanism driven by an electric motor, in order to pressurize the refrigerant fluid FR in the refrigerant circuit FR.
  • the electric compressor further comprises a control module for converting the electrical energy available on board the motor vehicle into electrical energy suitable for the electric motor of the electric compressor.
  • EP2873858 which describes such an electric compressor comprising a housing housing a mechanism for compressing the refrigerant fluid FR.

  • the housing also houses a control module for controlling the electric motor.
  • the electric motor, the control mechanism and the control module are aligned along a longitudinal axis of the electric compressor. More specifically, the electric motor is located in an axially intermediate position between the compression mechanism and the control module.
  • the housing includes an inlet port of the refrigerant fluid FR in the electric compressor.
  • the input port is the means by which the refrigerant FR is admitted inside the electric compressor.
  • the input port is arranged radially with respect to an axis of rotation of the rotor, the axis of rotation of the rotor being parallel, or even coincidental, with the longitudinal axis of the electric compressor.
  • the input port is included within a radial plane which is orthogonal to the axis of rotation of the rotor.
  • the input port is located opposite the electrical coils of the stator.
  • This configuration is not optimal because the refrigerant FR enters the interior of the electric compressor in a radial direction, orthogonal to the longitudinal axis of the electric compressor. It follows that the refrigerant fluid FR strikes an electric coil body located axially substantially in the middle of the coils, that is to say located substantially equidistant from the longitudinal ends of said electric coils. This results in a significant loss of charge for the refrigerant fluid FR that is desirable to minimize. This also results in a reduction in the cooling of the longitudinal ends of the coils while the latter are the parts of the coils which tend to heat up the most. Subsequently, it also results in a low cooling of the control module that can lead to failures of the electric compressor.
