Definitions

  • tube bundle evaporator exchangers It is well known in the art to manufacture tube bundle evaporator exchangers. These devices are used in many applications, in particular in air conditioners either for fixed installations or for vehicles.
  • the heat exchange surface of the evaporator exchangers must be large with the ambient air; this necessity leads to providing a large number of relatively short circuits in the same exchanger so that it is efficient while being compact.
  • the distribution of the refrigerant in the evaporator requires the use of relatively complex means, for example a large number of small tubes which must supply the different circuits of the exchanger independently.
  • FR-A-2 539 857 describes a distributor which divides the refrigerant into several partial flows to then bring the fluid through grooves of the same length which are delimited by two superimposed plates and which conduct the refrigerant to the evaporator tubes.
  • the invention eliminates the drawbacks mentioned above by creating an extremely simple and inexpensive structure.
  • the exchanger of the evaporator type for refrigerant comprising a tubular bundle, the tubes of which open into a honeycombed distribution plate distributing the refrigerant in independent tubes or sets of independent tubes is characterized in that the distribution plate is covered by a distributor plate to which is connected a refrigerant supply pipe, the plate having at least one series of conduits or holes calibrated to standardize the distribution of the refrigerant in the distributing cells of the different tubes or sets of tubes.
  • 1 denotes tubes preferably tubes bent into pins of an evaporator for refrigerant of a cooling installation, in particular of air conditioning.
  • the tubes 1 are engaged in a collector plate 2 made of synthetic material in which the ends of the tubes are for example fixed by means of an adhesive placed in grooves 3.
  • the tubes 1 are advantageously connected to secondary dissipators, for example fins in which they may have been inflated before being introduced into the collecting plate 2.
  • a reinforcing plate 4 is advantageously provided near the bent part 1 has tubes.
  • the collector plate 2 is covered and fixed in a sealed manner by welding or gluing to a distributor plate 5 which makes the ends of the tubes 1 communicate with each other to create circulation circuits multiple as shown in fig. 3 which by way of example shows circuits I, II, III, etc.
  • the various circuits above are all supplied from cells 6 formed by the distributor plate, for example on one of its lateral sides.
  • the cells 6 communicate with intermediate cells 7 by means of pinned tubes 1 and some of the intermediate cells 7, for example those designated by 7 a communicate with a receiving conduit 8.
  • the cells 6 like the receiving conduit 8 communicate respectively with supply 9 and outlet 10 collectors formed or attached above a distribution plate 11, itself fixed by gluing or welding to the distribution plate 5.
  • the intake manifold 9 is connected to an intake manifold 12 and the outlet manifold 10 to an evacuation manifold 13.
  • the distributor plate 11 has, above the cells 6, calibrated conduits 14, the section of which can be progressive, for example the calibrated conduit 14 disposed opposite the supply pipe 12 may be of smaller section than the conduits further away from the tube 12 in order to distribute the refrigerant uniformly in the different cells 6 and, consequently, in the different circuits I, II, III, etc.
  • the distributor plate 11 is moreover pierced with at least one hole 15 to make the conduit 8 communicate with the evacuation pipe 13.
  • the conduits 12, 13 can be provided, as illustrated in FIG. 1, a thermostatic expansion valve 16 or it is possible to provide a simple capillary injector, well known in the art and, therefore, not shown, which is arranged in the supply pipe 12.
  • Fig. 4 illustrates a variant in which the plate 11 is made thicker and is then designated by the reference 11 a .
  • the calibrated conduits 14 are replaced by capillaries 14 has a crescent section from the position of the feed tube 12 to the parts furthest from the tubing.
  • the capillary conduits forming independent regulators can come directly from molding.
  • conduits can only interest the cells 6 but they can be provided to correspond to several rows of cells 6.
  • the parts described above namely the collecting plate, the reinforcing plate and the distributing plate, etc. being preferably made of synthetic material, these parts can be easily assembled by welding, by friction or by gluing.
  • the tubes as well as the tubes can for their part be assembled by gluing, which makes possible a particularly inexpensive manufacture.
  • the collector plate 21 has centering recesses 16 for the tubes 1, these recesses define an enlarged part for the introduction of an adhesive.
  • the centering recesses extend over only part of the thickness of the plate which delimits, above said recesses, conduits or capillary calibrated holes 14a whose section is determined in particular as a function of the enlargement of the supply tube 12 described in the foregoing.
  • the part of the collector plate 21 which presents the conduits or holes 14a is covered by a distributor plate 5 similar to that already described and into which the inlet nozzles 12 and evacuation nozzles 13 open.
