Definitions

  • the present invention relates to installations for cooling (refrigeration or air conditioning) in which the liquid to be cooled is treated inside a intratubular type heat exchanger through which a two-phase refrigerant.
  • such an exchanger is presented generally in the form of a closed cylindrical envelope 1 at its ends by two flanges 2 and 3.
  • a transverse partition 4 pierced with holes, the space defined between the flange 3 and this partition 4 being divided by a diametrical wall 5 in two separate rooms, namely an admission room 6 and a delivery chamber 7 to each of which is associated a pipe or tubing 8, respectively 9, connected to a source of pressurized refrigerant.
  • the space 10 between the partition 4 and the flange 2 contains a multitude of heat exchange tubes 11 in shape curls or straight elbow portions with ends are engaged in the holes of the partition 4 of so as to ensure the connection between chambers 6 and 7 for the circulation of the refrigerant.
  • the liquid to be cooled (water or other) is allowed in space 10 of enclosure 1 through an inlet tube 12 and emerges through a tube outlet 13 after being cooled in contact with the tubes curly 11.
  • DE-A-32 12 914 which describes a distributor for heat exchanger, formed by a sheet folded in the shape of a spherical cap. This distributor does not allow however not achieve satisfactory results in a two-phase use.
  • the distributor according to the invention is mainly remarkable in that it is constituted by a sheet which is shaped like a spherical cap open in direction of the outlet of the intake manifold and which presents a series of perforations arranged around a full central part of the dispenser.
  • figure 1 indicates the structure general of a common intratubular heat exchanger
  • Figure 2 schematically recalls the arrangement of a conventional type two-phase distributor.
  • Figure 3 is an axial section of an intake manifold equipped with a dispenser according to the present invention.
  • Figure 4 shows in the same way a variant of realization of the distributor according to figure 3.
  • Figure 5 is an elevational view of a dispenser established in accordance with the preferred mode of implementation of the invention.
  • Figure 6 is an axial section of the following distributor figure 5.
  • the two-phase distributor shown in FIG. 3 is constituted by a stamped sheet metal 15 so as to be in the form of a spherical cap.
  • the central part 15 a is provided full while the peripheral zone is pierced with a series of perforations 15 b , advantageously arranged in concentric rows, the number of which varies according to the diameter of the sheet or part 15.
  • This part 15 is fixed in any suitable manner (welding for example) by its edge against the inner wall of the flange 3 of the exchanger, so as to be oriented along the axis of the outlet of the intake manifold 8 in the chamber 6 of said exchanger.
  • the two-phase refrigerant which travels under pressure this pipe 8 is forced to pass through the perforations 15b .
  • the turbulence generated by the impact of this fluid against the solid central part 15 a and by the resistance exerted by said perforations in the passage of said fluid ensures the effective mixing of the two phases of the latter, so that under these conditions a efficient homogenization inside the intake chamber 6 which feeds the looped tubes 11.
  • FIG. 4 illustrates a variant in which the whole of the spherical cap, here referenced 16, is pierced with perforations 16 b , the solid central part being obtained using a patch 16 a attached to the inside of said cap along a cord in the axial section of Figure 4.
  • the result obtained is identical to that of the embodiment according to Figure 3, the manufacturing costs being remarkably reduced in one case as in the other.
  • the homogenization of the two-phase refrigerant is appreciably improved when adopting the embodiment illustrated in FIG. 5 and 6.
  • the spherical cap 17 is pierced with perforations 17 b over its entire surface, as in FIG. 4, and the central zone full is obtained by bringing inside said cap 17, no longer a flat piece or patch, but a conical body 17 a , the tip of which is engaged inside the tube 8.
  • the conical body 17 a favors bursting of the refrigerating fluid and its division in the direction of the perforated peripheral zone.
  • the conical profile body 17 a is provided, on its outer surface, with grooves extending parallel to the axis of this body 17 a , that is to say parallel to the direction of flow of the fluid in tubing 8.
  • These grooves extend at least between the base of the cone and the outlet of the fluid intake manifold.
