Definitions

  • the present invention relates to a heat exchanger of the tube and fin type, the tubes of which are engaged in collecting plates to which they are connected by means of elastic bands or sleeves.
  • the invention solves the problem exposed by creating a new heat exchanger with tubes locked to the collector.
  • the heat exchanger with tubes locked to the manifold comprising fins threaded onto the tubes which are themselves engaged in collars of elastic material arranged in the tube passages of a manifold plate, is characterized by stop elements having at least one hole with a diameter smaller than the outside diameter of the tubes, said stop element being force-fitted on the projecting end in the collec plate trice at least some of the tubes to which it is connected.
  • 1 designates circulation tubes of round section of a heat exchanger on which are threaded cooling fins 2.
  • the fins 2 are folded over their short sides as shown in 2a so that the successive fins are in contact with each other to delimit lateral guides for the air which must pass through the exchanger.
  • the exchanger comprises manifold plates 3 which, in the embodiment of FIGS. 1 to 8, are made of synthetic material.
  • the collector plates 3 delimit passages of tubes 4 in which are engaged deformable collars 5, projecting from a sheet or elastic plate 6, for example made of rubber.
  • the tubes 1 are forcibly engaged in the collars 5 to protrude above them.
  • Stop elements 7 are then placed on at least some of the projecting ends of the tubes 1.
  • the stop elements are, for example, placed on the last two rows of tubes as illustrated in FIG. 1. They could obviously be placed on all the tubes but this is generally not necessary.
  • the stop elements illustrated in fig. 1 and 4 consist of washers, for example of circular shape, which have a hole 8 in their center.
  • radial cutouts 9 start from the hole 8 and extend over part of the washer.
  • notches 10 are provided from the hole 8.
  • the washers thus define tabs 11 with sharp edges.
  • the stop elements may be planar, but preferably they have a hemispherical shape whose convexity is turned upwards.
  • the diameter of the hole 8 is smaller than the outside diameter of the tubes 1.
  • the stop elements are force-fitted onto the ends of the tubes 1 in order to tighten the wall of the latter strongly at the same time as their underside deforms the projecting part 5a (FIG. 2) of the collars 5.
  • Fig. 2 also shows that the peripheral edge 7a of the planar stop elements advantageously presses on the top of the collector plate 3.
  • the sharp edges 11 of the stop elements tend to become embedded in the wall of the tubes l, mainly if these tubes tended to be moved down relative to the collector plate 3. It is ensured in this way that the tubes are perfectly immobilized relative to the collector plate.
  • a water box 12 is mounted on the collecting plate 3 and the edge 12a thereof is fixed, for example welded by vibration, to the peripheral edge corresponding to the collector plate.
  • a notch or groove 15 is defined in at least part of the peripheral edge of the water box 12 to cover the edge of the plate 7 1 , for example on three sides as illustrated in 15a in fig. 8 or two sides as shown in fig. 11.
  • the inside of the water box 12 is fitted with candles 17 corresponding to the pins 14.
  • the assembly of the exchanger can then be carried out by forcing the tubes 1 of the previously prepared exchanger bundle, that is to say fitted with fins 2 into the collars and the holes 8 of the stop element, the mode of action is then exactly the same as that described in the foregoing.
  • the collector plate 3 1 is made of metal, that the sheet 6 of flexible elastic material forming the collars 5 is placed on the face of the said collector plate which faces the water box 12. This is what particular case which is shown in fig. 9.
  • the water box may be made of synthetic material or metal and advantageously assembled with the collecting plate by mechanical means, for example a crimping piece 18.
