Definitions

  • the refrigeration system includes a compressor 10 that compresses the refrigerant in a high-temperature and high-pressure gaseous state, a condenser 20 that condenses refrigerant compressed by the compressor 10 into a liquid state by heat radiation using air blowing of a cooling fan 22, a capillary tube 40 that expands the liquid refrigerant condensed by the condenser 20 into low-pressure liquid refrigerant by a throttle operation, a distributor 30 that evenly distributes the liquid refrigerant condensed by the condenser 20 to the capillary tube 40, and an evaporator 50 that evaporates the low-temperature and low-pressure refrigerant expanded by the capillary tube 40 into low-temperature and low-pressure gaseous refrigerant at the same time when providing cool air by using evaporation latent heat while evaporating the low-temperature and low-pressure refrigerant expanded by the capillary tube 40 by air blowing of the cooling fan 52. Accordingly,
  • the distributor body 110 is formed in a hollow cylindrical shape having generally the same diameter. Accordingly, an inner diameter and an outer diameter of the distributor body 110 generally have the same value.
  • an inlet flow passage 111 and a mixed flow passage 113 are provided in the distributor body 110.
  • a distribution projection 125 is provided in the distributor head 120 corresponding to an inner part of the distribution flow passage 121.
  • a part of the downstream portion of the mixing unit 122 excluding a portion which is in communication with the upstream end portion of the distribution unit 123 is projected in a direction opposite to the flowing direction of the refrigerant to form the distribution projection 125.
  • the distribution projection 125 has the cone shape as a whole, but the shape of the distribution projection 125 is not limited thereto.
  • the distribution projection 125 is configured to evenly distribute the refrigerant that flows on the mixing unit 122 to the distribution unit 123. That is, the refrigerant that flows on the distribution unit 123 flows substantially toward the distribution unit 123 by the distribution projection 125. Further, the distribution projection 125 serves to reduce the flow cross-sectional area of the downstream portion of the mixing unit 122 which is in communication with the distribution unit 123 toward the distribution unit 123.
  • the liquid and gaseous refrigerants transferred to the distribution flow passage 121 are remixed in the mixing unit 122 of the distribution flow passage 121 having the flow cross-sectional area comparatively larger than the mixed flow passage 113.
  • the liquid and gaseous refrigerants that are remixed in the mixing unit 122 are transferred to the outlet pipe 20 connected to the distribution unit 123 through the distribution unit 123 of the distribution flow passage 121.
