Definitions

  • the present invention relates to a module for exchanging heat, comprising a main exchanger and at least one secondary exchanger each comprising a body provided with tubes fluid circulation, and latching means for fix the secondary exchanger on the main exchanger of so that the same air flow can pass through the bodies respective of said exchangers.
  • Such exchangers are generally in the form a body provided with fluid circulation tubes and fins heat exchange with the outside environment. This body is arranged between two manifolds that distribute the fluid in the circulation tubes.
  • the assembly of the secondary exchanger (s) on the exchanger principal is usually obtained through lugs integral with the secondary exchanger and screws introduced into the exchanger manifolds main. Assembly systems have also been proposed by fitting or snapping on the manifolds.
  • the connecting members between the exchangers main and secondary occupy a certain volume which harms the compactness of the module.
  • the manifolds have a significant thickness. The thickness of the module is therefore not conditioned by the cumulative thicknesses of body of exchangers, i.e. tube assemblies, but by the cumulative thicknesses of the manifolds, significantly more important.
  • these liaison bodies have a certain transverse dimensions and therefore do not allow have the same exchange surface for exchangers main and secondary.
  • the present invention aims to overcome these drawbacks.
  • the invention aims to provide a heat exchange module, the production of which, and in particular assembly operations, as simple as possible.
  • the invention also aims to provide such a module heat exchange which, as far as possible, does not no assembly parts between the exchangers main and secondary.
  • the invention further aims to provide a method of making a heat exchange module that does not require any operation assembly or, when this is not possible, by with a minimum.
  • the invention also aims to provide such a module heat exchange thinner than those of art prior.
  • the invention also aims to provide a module heat exchange with exchange characteristics thermal improvements.
  • the exchangers are therefore assembled by their body, by through their tubes and shaped organs comb.
  • the module may also have dimensions less important. Indeed, the comb-shaped organs can be entirely in the space between the bodies and do not in this case do not extend beyond the cross section of the exchangers. In addition, the bodies can also be brought together as we wish.
  • said means of mounting of the comb-shaped member on the first of said exchangers include a second row of teeth with between them, two by two, a form interval substantially corresponding to the cross section of fluid circulation tubes of the first of said exchangers, so as to snap said comb-shaped member onto the body of the first exchanger.
  • said means for mounting the comb-shaped member on the first said exchangers include a set of holes in which are engaged the fluid circulation tubes of the first exchanger.
  • the comb-shaped member may include a strip of support and teeth substantially in the plane of the band, the plane of this organ being substantially perpendicular to the plans of the exchanger bodies.
  • said comb-shaped member may include a support strip and teeth in a plane substantially perpendicular to the plane of the strip, the plane of the strip is finding substantially parallel to the planes of the bodies of exchangers.
  • the heat exchange module according to the invention may include at least two organs in the form of comb, said organs belonging to two sides of a frame assembly arranged to receive said heat exchangers through comb-shaped organs.
  • the heat exchange module according to the invention may include a tubular frame with two comb-shaped members whose support bands are arranged inside the frame, along two sides opposite of the latter, in a middle part of these sides in the axial direction.
  • the member in the form of comb has a recess, preferably substantially parallel to the exchanger plane, between the mounting means on the first exchanger and the first row of teeth.
  • the recess can extend over the entire length of the comb-shaped organ or only at the ends of this last.
  • This arrangement makes it possible to assemble exchangers of dimensions different.
  • said comb-shaped member is mounted on the first exchanger during the realization of the latter.
  • said shaped organ of comb is snapped onto the body of the first exchanger after completion of the latter.
  • a heat exchange module comprising two heat exchangers, namely a radiator 1 of cooling of a motor vehicle engine provided with its motor-fan unit 2, and an air conditioning condenser 3.
  • the radiator 1 consists in a known manner of a body 4 mounted between two manifolds 5 and 6, the box manifold 6 being provided with inlet pipes 7 and coolant outlet.
  • the body 4 is produced from a bundle of tubes horizontal 8 for fluid circulation (figure 4), not shown individually in Figure 1. These tubes are here circular section tubes distributed on two layers perpendicular to the vehicle's AV direction of travel.
  • the condenser 3 also consists of a body 9 mounted between two manifolds 10 and 11, the manifold 10 being provided with inlet and outlet pipes 12 fluid.
  • the body 9 is produced from a bundle of tubes of horizontal fluid circulation 13 (Figure 4).
  • Tubes 13 are internally partitioned flat tubes, again called multi-channel tubes, the plane of which is arranged parallel to the AV advance direction of the vehicle. These tubes 13 are distributed on a single tablecloth perpendicular to the direction AV.
  • heat exchangers 1 and 3 are assembled by their bodies 4 and 9 respectively, via of two comb-shaped members 14, one of which section is shown in detail in Figure 3.
  • Each member 14 has a generally planar shape elongated, with a solid central strip 15 provided along each of its long sides of a row of couple of teeth, 16, 17 respectively, thus forming two opposite combs in the plan of the strip 15.
  • the pairs of teeth 16 are spaced at the transverse pitch of the tubes 8, and form between these teeth a slot 18 of width slightly smaller than the diameter of the tubes 8.
  • This slot has two enlarged zones, one 19 at the bottom of the slot, and the other 20 near the edge of the slot.
  • the enlarged zones 19 and 20 generally have a shape circular with a diameter substantially equal to that of the tubes 8. Their centers are spaced along slot 18 of a distance substantially equal to the distance between the two tube sheets 8.
  • the pairs of teeth 17 are spaced at the transverse pitch of the tubes 13, and form between these teeth a slot 21 of a depth substantially equal to the width of the tubes 13 and of a width substantially equal to the thickness of these tubes.
  • Each slot 21 has a rounded bottom and is partially closed by a retaining spout 22 projecting from the end of each tooth inward of the slot.
  • the members 14 are made for example of plastic, and are cut on demand according to the height of the heat exchange module. As shown in Figure 4, each organ is snapped in the first place for example on the tubes 8 of the exchanger 1 by its teeth 16, then the tubes 13 of the exchanger 3 are snapped onto the teeth 17 of the member 14 for assembling the module.
  • each organ 14 is therefore, in the present embodiment, substantially perpendicular to the planes plies of tubes 8 and 13.
  • the bands 15 of each member 14 provide lateral sealing function for flow air between the two exchangers.
  • Figure 2 shows a variant in which the teeth 23 to engage the exchanger 1, and 24 to snap on the exchanger 3, are mounted on a frame 25.
  • the frame 25 has, in the direction of the arrow AV, a generally tubular shape with rectangular section, of dimensions slightly greater than the plan dimensions of heat exchangers 1 and 3.
  • two bands 26 are attached to the opposite vertical sides of this frame, protruding towards the inside of the latter, therefore substantially perpendicular to the direction of the arrow AV.
  • the teeth latching 23 and 24 are arranged along the edge inside of the bands 26, perpendicular to the plane of these strips, therefore protruding in the direction of the arrow AV.
  • the shape and pitch of the teeth 23 are identical to those of the teeth 16, as well as the shape and pitch of teeth 24 are identical to those of teeth 17.
  • the assembly of the heat exchange module is then done by successively engaging the tubes 8 of the exchanger 1 and 13 of the exchanger 3 on the frame 25, via the teeth 23 and 24 respectively.
  • the lateral seal between the two exchangers is provided by the frame 25 which forms a circulation nozzle of air in which the two exchangers are interposed.
  • the tubular frame 25 can have axially, that is to say in the direction of the arrow AV, a dimension substantially equal to the thickness of the module, which it therefore substantially envelops totally.
  • the comb-shaped member 27 (FIG. 5) always includes a solid central strip 28 but, if one of the longitudinal edges of this band is always provided with pairs of teeth 29 for the locking of the tubes of one of the heat exchangers heat, its other edge has holes 30 of shape and dimensions corresponding to the tubes of the other heat exchanger heat.
  • the two exchangers ( Figure 6) are single-ply exchangers of flat tubes
  • the heat exchange module is then assembled by including the members 27 during the production of the corresponding exchanger at holes 30.
  • the second exchanger is then snapped onto teeth 29.
  • this embodiment allows assembly three heat exchangers, providing a second row of teeth on the other side of the holes 30, along the edge of the member 27 opposite the teeth 29.
  • FIGS. 7 and 8 show the two exchangers 1 and 3 of different dimensions and assembled using a comb shape 31 comprising, as described above, holes 32 for the passage of the exchanger 1 tubes and teeth 33 for receiving the tubes of the exchanger 3.
  • the comb-shaped organ 31 has a substantially perpendicular recess 34 to the planes of said member in which the holes 32 are formed and the teeth 33, recess situated between the plane in which are formed the holes 32 and the plane in which are formed teeth 33, and which is therefore after mounting substantially parallel to the plans of exchangers 1 and 3.
  • the recess 34 is here carried out in two parts at the ends of the comb-shaped member 31.
  • the teeth 33 which are linked to this setback therefore only appear in these end parts.
  • Figure 9 shows a comb-shaped member 35 which is an alternative embodiment of the comb-shaped member 31 Figures 7 and 8. The same references have been used.
  • the recess 34 extends over the entire length of the comb-shaped member 35, same therefore as the teeth 33. Furthermore the holes of passage of the heat exchanger tubes 1 have been replaced by teeth 36.
  • the heat exchange modules in Figures 7 to 9 can have one or two comb-shaped members such as those which have just been described, to one or each of their extremities.
  • the setback can be achieved over the entire length of the comb-shaped organ or only at the ends of the latter regardless of the type of means of mounting (teeth or holes) used for assembling the first exchanger.
