    HEAT EXCHANGE DEVICE COMPRISING A PROTECTION DEVICE
    The invention relates to a heat exchange device for a motor vehicle comprising a heat exchanger and a device for protecting the heat exchanger. The invention also relates to a method of assembling such a heat exchange device. The invention relates more particularly to a heat exchange device placed on the front face of a motor vehicle.
    In the automotive field, the heat exchangers placed on the front face can be victims of projections of debris, in particular stones, which can damage the heat exchanger. In particular, this debris can pierce the tubes of the heat exchanger, inside which circulates a fluid to be cooled by means of the air flow created by the rolling motor vehicle.
    In order to protect these heat exchangers, it is known to place in front of them, in the direction of normal operation of the motor vehicle, a protective device capable of absorbing shocks due to projections of debris. The protection device is in particular a grid.
    Thus, for example, in document US-A-2007/080009, it is proposed to fix the protection device on the bumper of the motor vehicle.
    Document US-A-2005/029028 teaches for its part to fix the protection device on a frame arranged upstream, relative to the direction of the air flow passing through the heat exchanger, of the bundle of tubes.
    Finally, application JP 2012 229 907 describes a heat exchange device comprising a grid fixed to the water boxes of the heat exchanger, arranged on either side of the tube bundle (s) crossed by the fluid to be cooled. .
    These methods of attaching the protection device are bulky, in that they significantly increase the volume occupied by the heat exchange device consisting of the heat exchanger and the protection device.
    Furthermore, application FR 15 54 049, in the name of the applicant, describes a heat exchange device, in the case of which the protection device comprises fixing peaks extending substantially perpendicular to the grid, the peaks of fixing being inserted by force between fins separating the tubes from the tube bundle. The fins can, however, deform which can affect the attachment of the protection device.
    Finally, application FR 15 54 050, still in the name of the applicant, describes a heat exchange device provided with a protective grid with hooks. The protective grid is placed opposite the front face of the heat exchanger, so that the hooks overlap the side faces of the heat exchanger and come into engagement with the rear face of this heat exchanger. However, this device induces increased bulk compared to the single heat exchanger.
    There is therefore a need for a heat exchange device which does not have at least certain drawbacks of the devices of the prior art.
    To this end, the invention provides a heat exchange device for a motor vehicle comprising:
    - a heat exchanger, with o a first collecting plate and a second collecting plate, extending mainly in a longitudinal direction, o a first water box, fixed on the first collecting plate, and a second water box, fixed on the second collector plate, and o at least one bundle of tubes extending between the first and second collector plates in a longitudinal direction of the tubes, o each of the first and second collector plate forming, between the tubes of the bundle of tubes and a lateral end of the respective collector plate, a groove extending substantially in the longitudinal direction of the respective collector plate, perpendicular to the longitudinal direction of the tubes, and
    - a device for protecting the tubes of the bundle of tubes, perforated, comprising fixing means on the heat exchanger, the fixing means taking support inside the grooves formed by the first and second collector plates.
    Thus, the protection device is fixed directly to the heat exchanger. Advantageously, it is thus possible to conform the protection device so that it does not protrude laterally from the heat exchanger, and, thus, the size of the heat exchange device is limited.
    This attachment to the collector plates is moreover robust, in particular when the collector plates are made of metallic material.
    According to preferred embodiments, the heat exchange device according to the invention has one or more of the following characteristics, taken alone or in combination:
    the fixing means comprise at least one elastic casing relief received in one of the groove of the first collecting plate and the groove of the second collecting plate, the fixing means preferably comprising a plurality of such casing reliefs elastic received in one of the groove of the first collector plate and the groove of the second collector plate, said elastic casing reliefs preferably being evenly distributed;

    the protection device comprises a grid, the grid preferably having bars, the grid more preferably comprising bars extending in a direction parallel to the tubes and / or bars extending perpendicular to the direction of the tubes;
    the grid comprises as many bars extending parallel to the tubes, as the tube bundle does not comprise tubes;
    the heat exchange device further comprises an insert extending at least partly around the protection device; the insert is an air guide, in particular an air guide of the converging type;
    the insert is fixed to the first and / or the second water box; the insert comprises elastic casing reliefs on the first and / or second water box, the first and / or the second water box preferably comprising reliefs complementary to said elastic casing reliefs of the insert; and the protection device and / or the insert, if applicable, is / are made of plastic, in particular polyamide or polypropylene.
    According to another aspect, the invention relates to a method of assembling a heat exchange device as described above in all of its combinations, comprising a step of fixing the protection device, inside grooves formed by the first and second collector plates.
    According to a first variant, the step of fixing the protection device comprises a step consisting of elastically fitting the elastic fitting reliefs in the groove of the first collecting plate and in the groove of the second collecting plate, preferably in a substantially simultaneous.
    According to a second variant, the step of fixing the protection device comprises a first step of inserting the reliefs in the groove of one of the first collecting plate and the second collecting plate, then a step of pivoting the protection device, and finally a step of elastic fitting of the elastic fitting reliefs in the throat of the other from the first collecting plate and the second collecting plate.
    Preferably, the assembly method further includes a step of fixing an insert, in particular an air guide, on the water boxes, the insert preferably being fixed at least in part by elastic interlocking. on one of the water boxes.

    In the various figures, identical elements or identical functions bear the same reference numbers. These elements are not described in the case of each example. On the contrary, for the sake of brevity of the description, only the differences between the different examples are described in detail.
    FIG. 1 illustrates a first example of a heat exchange device 10. This essentially comprises a heat exchanger 12, a protection device 14 for the heat exchanger 12, and an insert 16 on the heat exchanger 12.
    The heat exchanger 12 is more clearly visible in FIGS. 2 and 3. It comprises two bundles 18, 20 of tubes 22, intended to be traversed by a fluid to be cooled, the tubes 22 of the same bundle 18, 20 being separated by fins 24.
    The first bundle of tubes 18 is arranged parallel to the second bundle of tubes 20, offset in the direction of the air flow F formed by the vehicle when it is traveling. The tubes 22 of the two beams 18, 20 extend mainly in a common longitudinal direction Y, between a first collecting plate 26 and a second collecting plate 28. Each collecting plate 26, 28, extends mainly in a longitudinal direction X. The collector plates 26, 28 are here parallel, perpendicular to the longitudinal direction Y of the tubes.
    A first water box 30 is fixed to the first collecting plate 26. This water box 30 here consists of a cover, preferably made of plastic. Here, this first water box 30 defines a first volume 32 in fluid communication with, on the one hand, a fluid inlet 34 of the heat exchanger 12, formed by the first water box 30, and, on the other share, the first bundle of tubes 18. The first bundle of tubes 18 is advantageously the one which is intended to be in contact with the air flow F, after the latter has passed through the second bundle of tubes 20. The first water box 30 also forms a second volume 36, in fluid communication with, on the one hand, a fluid outlet 38, formed by the first water box 30, and, on the other hand, with the second bundle of tubes 20.
    As is more particularly visible in FIG. 3, the side walls 40, 42 of the first water box 30 are received in a groove 44 of the first collecting plate 26, formed by a fold or embossing 46 of the first collecting plate 26 This first groove 44 extends over substantially the entire contour of the first collector plate 26. The groove 44 of the first collector plate 26 can receive a seal interposed between the side walls 40, 42 of the first water box 30 and the first collecting plate 26, in order to limit or even avoid any leakage of liquid from the volumes 32, 36 formed inside the first water box 30.
    On the side opposite to the side walls 40, 42 of the first water box 30, the embossing 46 of the first collecting plate 26 forms a projecting rib 48 extending between the tubes 22 of the first and second bundles 18, 20 and one end lateral 50, 52 of the first collector plate 26. This projecting rib 48 defines in particular, at the lateral end 50 of the first collector plate 26, intended to be oriented towards the front of the vehicle (that is to say say, here, the lateral end 50 of the first collecting plate 26 which is closest to the second bundle of tubes 20) a groove 54, which extends between the projecting rib 48 and the tubes 22 of the second bundle of tubes 20 This groove 54 extends essentially in the longitudinal direction X of the first collector plate 26 and therefore perpendicular to the tubes 22 of the second bundle of tubes 20.
    Similarly, a second water box 56 is fixed to the second collector plate 28. This second water box here consists of a cover, preferably made of plastic. The second water box 28 here defines a volume 57 in fluid communication with the outlet of the tubes 22 of the first bundle of tubes 18, on the one hand, and with the inlet of the tubes 22 of the second bundle of tubes 20, moreover .
    The side walls 58, 60 of the second water box 56 are received in a groove 62 of the second collector plate 28, formed by a fold or an embossing 64 of the second collector plate 28. This second groove 62 extends over substantially the entire contour of the second collector plate 28. The groove 62 in the second collector plate 28 can receive a seal interposed between the side walls 58, 60 of the second water box 56 and the second collector plate 28, to limit or even avoid any leakage of liquid outside the volume 57 defined inside the second water box 56.
    On the side opposite to the side walls 58, 60 of the second water box 56, the embossing 64 of the second collector plate 28 forms a projecting rib 66 extending between the tubes 22 of the first and second bundles 18, 20 and one end lateral 68, 70 of the second collector plate 28. This projecting rib 66 defines in particular, at the lateral end 68 of the second collector plate 28, intended to be oriented towards the front of the vehicle (that is to say say, here, the lateral end 68 of the second collector plate 28 which is closest to the second bundle of tubes 20) a groove 72, which extends between the projecting rib 66 and the tubes 22 of the second bundle of tubes 20 This groove 72 extends essentially in the longitudinal direction X of the second collector plate 28 and therefore perpendicular to the tubes 22 of the second bundle of tubes 20.
    The heat exchanger 12 finally comprises two lateral cheeks 74, 76 extending mainly in the longitudinal direction Y of the tubes 22 of the two bundles of tubes 18, 20.
    Furthermore, the protection device 14 of the heat exchange device 10 is shown in more detail in FIG. 4. Here, this protection device 14 is produced in the form of a perforated planar surface 77, with means for fastening comprising relief reliefs 78 at a first longitudinal end 77a of the perforated flat surface 77, and elastic fitting reliefs 80 at a second longitudinal end 77b of the perforated surface 77, opposite the first longitudinal end 77a .
    Here, the perforated flat surface is produced in the form of a grid 77. In the example shown, all the bars of the grid 77 are parallel, extending in a corresponding longitudinal direction Y, once the grid 77 is mounted on the heat exchanger 12, in the longitudinal direction Y of the tubes 22 of the first and second bundles of tubes 18, 20. Advantageously, the grid 77 has as many bars as the second bundle of tubes 20 does not include tubes 18. Thus, advantageously, a bar of the grid 77 can be placed opposite a tube 22 of the second bundle of tubes 20, thus optimizing the protection provided by the protection device 14. The grid 77 can in particular be made of plastic material, by for example polyamide or polypropylene. Thus, the grid 77 can easily be produced, in particular by molding. In addition, the weight of the protective device 14 is thus limited.
    Of course, the orientation of the bars can be chosen differently, in particular perpendicular to the longitudinal direction of the tubes 22. Alternatively, the grid can include bars which are not parallel. In particular, the grid may include perpendicular bars, a first group of bars extending for example parallel to the longitudinal direction Y of the tubes 22, while a second group of bars extends perpendicular to the first group of bars, c ' that is to say parallel to the longitudinal direction X of the first and second manifold plates 26, 28, once the grid 77 is mounted on the heat exchanger 12.
    The relief reliefs 78 are here three in number, without this number being limiting. The support reliefs 78 are advantageously evenly distributed over the length of the first longitudinal end 77a of the grid 77. As illustrated in particular in FIG. 5a, the support reliefs 78 have substantially an "L" shape, with two branches 78a, 78b perpendicular, an appendage 78c connecting the "L" to the grid 77.
    The elastic casing reliefs (or clipping) 80 are also three in this case, without this number being limiting. The elastic casing reliefs 80 are distributed equally over the length of the second longitudinal end 77b of the grid 77.
    As illustrated in particular in FIG. 5D, the elastic casing reliefs 80 are formed by U-shaped tongues 80a, extending from one face of the protection device 14 opposite the face intended to be opposite. tubes 22 of the heat exchanger 12. The U-shape of the tongues 80a allows elastic deformation of the elastic casing reliefs 80. However, the tongues 80a extend in part, projecting from the face of the protection device 14 intended to be vis-à-vis the tubes 22 of the heat exchanger 12. In particular, the free end 80b of the elastic casing reliefs 80 projects from this face of the protection device 14 intended to be in look of the tubes 22 of the heat exchanger 12. Here, this free end 80b takes the form of a bent finger.
    The protective device 14 can be fixed to the heat exchanger 12 by proceeding as illustrated in FIGS. 5A to 5F.
    First of all, as illustrated in FIG. 5A, the relief reliefs 78 are inserted into the groove 72 formed by the second collector plate 28. More precisely, as can be seen in FIGS. 5B and 5C, a branch 78a of the “L” of the relief reliefs 78 comes to bear on the rib 66 of the second collector plate 28. Thus, the protection device is in abutment against the rib 66 of the second collector plate 28 in the longitudinal direction Y of the tubes, according to a first sense. In this position, the second branch 78b of the "L" of the support reliefs 78 is inserted into the groove 72 of the second collector plate 28. Preferably, the second branch 78b of the "L" of the support reliefs 78 is in contact with the rib 66 defining the groove 72, so that the protection device 14 abuts against the rib 66 of the second collector plate 28, also in a direction Z, normal to the directions X of the collector plates and Y of the tubes, according to a sense.
    The protection device 14 is then pivoted, as illustrated in FIG. 5D, around an axis substantially parallel to the longitudinal direction X of the second collector plate 28, while maintaining the relief reliefs 78 abutting against the rib 66 of the second collector plate 28. The bent fingers 80b are then forcefully inserted into the elastic casing reliefs 80 in the groove 54 of the first collector plate 26. This forceful insertion is carried out with elastic deformation of the U-shaped tongue 80a , until reaching the position of FIGS. 5E and 5F. In these figures, the bent fingers 80b of the elastic casing reliefs 80 are received in abutment in the groove 54 of the first collector plate 26, in abutment on the rib 48 formed by the first collector plate 26. The bent fingers 80b are held in this position due to the elastic force applied by the "U" tabs 80a. This elastic force of the "U" tabs 80a also presses the relief reliefs 78 against the rib 64 of the second collector plate 28, in particular in the groove 72 of the second collector plate 28.
    It should be noted that advantageously, the second water box 56 is located below the first water box 30, once the heat exchange device 10 is mounted in the motor vehicle. Thus, the support reliefs 78 are also pressed against the rib 64 of the second collector plate 28 by the weight of the protective device 14.
    As described above, the protection device 14 is fixed directly on the collector plates 26, 28 of the heat exchanger 12. The protection device 14 can thus be shaped so as not to protrude laterally relative to the heat exchanger 12. In particular, the grid 77 or even the protection device 14 has a length, measured in the longitudinal direction X of the tubes 22, substantially equal to the distance between the collector plates 26, 28.
    In the absence of a lateral projection of the protection device 14 relative to the heat exchanger 12, an insert 16 can be fixed on the heat exchanger 12, in particular "above" the protection device 14, this is in other words, so that the protection device 14 is interposed between the heat exchanger 12 and the insert 16. The insert 16 can then extend at least in part around the protection device 14.
    In the example illustrated, in particular in FIG. 6, the insert 16 is an air guide, here of the converging type (hereinafter called "converging 16"). The convergent 16 is a funnel structure intended to ensure a greater flow of air through the bundles of tubes 18, 20. The convergent 16 is for example made of plastic, in particular polyamide or polypropylene.
    The convergent 16 has here, at a first longitudinal end 16a, two tongues 82, 84 intended to be received by sliding in the direction X, in complementary housings 86, 88 formed on the first water box 26. Each of the housings 86, 88 is provided with a stop surface in the direction of insertion of the tongues 82, 84. Advantageously, this direction of insertion corresponds to the direction of the weight of the convergent 16, once the heat exchange device 10 is mounted in the motor vehicle, so that this weight of the convergent 16 is supported by the stop of the housings 86, 88.
    At the second longitudinal end 16b of the convergent 16, it has two elastic fitting reliefs 90, 92 intended to cooperate with complementary reliefs 94, 96, formed on the second water box 56. Each elastic fitting relief 90 , 92 here takes the form of two parallel, symmetrical harpoons, the rod 90a, 92a of each harpoon 90, 92 being flexible enough to allow the hooks 90b, 92b to be brought closer together, by elastic deformation said rods 90a, 92a.
    As illustrated, the convergent 16 also has lateral edges 98 folded down towards the protective device 14 and intended to cooperate with the protective device 14 to limit the relative movements of the convergent 16 relative to the protective device 14. Here, the folded side edges 98 cooperate with the longitudinal edges of the grid 77.
    The convergent 16 can be fixed on the heat exchange device 12 as illustrated in FIGS. 7A to 7D.
    First, as illustrated in FIGS. 7A and 7B, the tongues 82, 84 of the convergent are inserted into the complementary housings 86, 88 of the first water box 30 according to the direction of insertion. The insertion of the tabs 86, 88 is carried out until these tabs 86, 88 are in abutment in the direction of insertion, against the abutment of the complementary housings 86, 88.
    Once the tabs 82, 84 have been inserted, the elastic casing reliefs 90, 92 of the convergent 16 are substantially opposite the complementary reliefs 94, 96 of the second water box 56. Pressure is then exerted on the second longitudinal end 16b of the convergent 16 for fitting the elastic casing reliefs 90, 92 of the convergent into the complementary reliefs 94, 96 of the second water box 56. It should be noted here that the pressure on the second end 16b of the convergent is exerted in a direction Z normal to the plane of the grid 77. In fact, the fixing by means of the elastic casing reliefs 90, 92 essentially aims at keeping the convergent 16 close to or even in contact with the grid 77. The position of the converge 16 in front of the grid 77 is essentially ensured by the reception of the tongues 82, 84 in abutment in the complementary housings 86, 88 of the first water box 30.
    FIG. 8 illustrates a second example of a heat exchange device 100. This heat exchange device 100 differs from the first example 10 essentially in that the protection device 14 is devoid of support reliefs 78. At each of its longitudinal ends 77a, 77b, the grid 77 is provided with elastic casing reliefs 80, similar to those of the first example 10.
    In this case, the fixing of the protective device 14 comprises a step consisting in elastically fitting the elastic fitting reliefs 80 in the groove 54 of the first collecting plate 26 and in the groove 72 of the second collecting plate 28. Insertion elastic casing reliefs 80 in the grooves 54, 72 of the first and second collector plates 26, 28 can be produced substantially simultaneously. By substantially simultaneous, it is meant here that the insertion is carried out at the same time, for example by a movement of the protection device 14 towards the heat exchanger 12, in a direction Z substantially normal to a plane defined by the longitudinal directions X , Y of the collector plates 26, 28 and of the tubes 22.
    The invention is not limited to the embodiments described above. On the contrary, it is susceptible to numerous variants accessible to those skilled in the art.
    In particular, the mounting of the protection device and / or of the insert can be carried out symmetrically, by reversing the role of the first and second manifold plates.
    Furthermore, the insert can be fixed to the heat exchanger by elastic fitting only. It suffices to replace the tabs of the example described by elastic casing reliefs.
    This insert may not be an air guide, but, for example, a frame or a support element, in particular made of plastic, for holding a component or a heat exchanger.
    Also, in the example described, the protection device comprises a grid. As a variant, the protection device can be produced in any form accessible to those skilled in the art, as long as it has days allowing the passage of at least part of the air flow F created by the movement of the vehicle. Preferably, the days of the protective device extend parallel to the tubes, the days being, more preferably, offset with respect to the tubes, in a direction parallel to the longitudinal direction of the first and / or the second collector plate.
    Finally, in the examples described, the heat exchanger is a heat exchanger with two methodical passes. The heat exchanger therefore comprises two bundles of coplanar tubes. Alternatively, the heat exchanger may have only one tube bundle or more than two tube bundles.
