Definitions

  • the present invention relates to reducing vibration noise generated in a rear housing, and more particularly to a scroll compressor.
  • the condenser cools the high-temperature, high-pressure refrigerant gas by exchanging heat with the outside air, thereby liquefying it, and the expansion valve adiabatically expands the liquid refrigerant, thereby lowering its temperature and pressure, making it easy to evaporate in the evaporator.
  • the evaporator absorbs heat from the liquid refrigerant and vaporizes it by exchanging heat with the outside air introduced into the vehicle.
  • the outside air is cooled by the refrigerant, and is then blown into the vehicle's interior by a blower.
  • Compressors are of two types: a reciprocating type, which compresses the working fluid (refrigerant) by reciprocating motion, and a rotary type, which compresses it by rotating motion.
  • reciprocating types there are a crank type, which transmits the driving force of a driving source to multiple pistons using a crank, a swash plate type, which transmits the force to a rotating shaft on which a swash plate is installed, and a wobble plate type, which uses a wobble plate.
  • a scroll compressor is a type of rotary compressor in which compression is achieved by two interlocking scrolls with involute teeth moving in a linear motion.
  • the above scroll compressor operates by having a rotating scroll and a fixed scroll that have a geometrical phase difference of 180 degrees relative to each other and rotate inside the discharge chamber, and the rotating scroll and the fixed scroll have scroll-shaped wings (wraps), and the wings are formed as involute curves having the same shape.
  • a scroll compressor forms a crescent-shaped compression chamber through the engagement of a rotating scroll and a fixed scroll, thereby completing a compression cycle.
  • the compression chamber is formed such that its volume increases toward the outside and decreases toward the center.
  • a suction chamber is formed on the outside and a discharge port is formed in the center.
  • compression is performed by sealing suction gas within a sealed space of a given volume around the outer periphery of the scroll and the relative rotation of the scroll gradually reducing the size of the compression space toward the discharge port and discharging it through the discharge port.
  • the refrigerant discharged from the above discharge chamber passes through the oil separation tube and is centrifugally separated before finally being discharged through the discharge port.
  • the centrifugal separation of oil can be stably achieved only when the refrigerant rotates stably.
  • the above conventional rear head (2) does not have a structure that can reduce vibration noise caused by the pressure of the discharged refrigerant, so a countermeasure for this became necessary.
  • Embodiments of the present invention aim to provide a scroll compressor that reduces vibration noise caused by shaking due to high-pressure refrigerant discharge by changing the structure of the rear housing.
  • a scroll compressor comprises: a housing (30); a compression unit (5) provided within the housing (30); a driving unit (3) provided within the housing (30) to drive the compression unit (5); the compression unit includes a fixed scroll and a rotating scroll that rotates relative to the fixed scroll, and refrigerant compressed in the compression unit is discharged to a discharge chamber unit formed in a rear housing through a discharge hole formed in the fixed scroll, and a curved portion is formed in the discharge chamber unit such that a surface facing the discharge hole is rounded inward.
  • the above-mentioned curved portion includes a first curved portion that is curved with a first curvature toward the inside of the rear housing from the upper side based on a curved vertex that is curved with a predetermined curvature; and a second curved portion that is curved with a second curvature toward the inside of the rear housing based on the curved vertex.
  • the above curved peak is formed above the discharge hole in the direction of gravity (G).
  • the above discharge chamber portion further includes a first chamber formed with a predetermined volume; a second chamber having an independent space via an internal partition wall from the first chamber; and a communication hole connecting the first chamber and the second chamber.
  • the first chamber has a larger area than the second chamber.
  • an oil storage chamber is formed with a predetermined size toward the direction of gravity (G).
  • the above inner bulkhead extends obliquely toward the oil storage chamber.
  • the above rear housing is formed with a protrusion that protrudes toward a position facing the discharge hole.
  • Embodiments of the present invention can reduce the occurrence of vibration and noise that occur in an environment where high-pressure refrigerant is discharged by changing the structure of the rear housing.
