    TECHNICAL FIELD OF THE INVENTION The invention relates to the field of heat exchangers for motor vehicles. The invention more particularly relates to a heat exchange module comprising a radiator and a functional element mutually connected to one another via a fixing means. The invention also relates to a vehicle comprising such a heat exchange module.
    State of the art
    Conventionally, a vehicle of the type of an automobile comprises a traction chain connected to a drive motor which may be of an electrical or thermal nature. To ensure optimum operation, it is necessary to use cooling systems whose function is to maintain a nominal operating temperature of a coolant flowing in particular in a cooling circuit of the engine.
    It is known that several cooling systems are embedded in a vehicle. By way of example, the cooling systems comprise a heat exchanger arranged in a cooling circuit of the engine, which can be qualified as a high temperature circuit since the cooling fluid evolves in temperature ranges of approximately between 80 and 100 °. C, a heat exchanger disposed in an air conditioning circuit and a heat exchanger disposed in a cooling circuit of an accessory, which can be described as a low temperature circuit since the cooling fluid evolves in temperature ranges between approximately 40 and 60 ° C.
    The heat exchangers are stacked on top of one another in a superposition to form a heat exchange module. Such a heat exchange module is disposed on the front of the vehicle and is intended to be traversed by a stream of air to cool the cooling fluid or refrigeration.
    In a desire to pool said means used in the implementation of such a cooling system, some heat exchangers of a heat exchange module must be used in different designs of the heat exchange module. Indeed, the need for cooling but also the very existence of cooling for a low temperature circuit or an air conditioning circuit are not identical in all categories or variants of vehicle design. By way of example, some vehicles comprise a high temperature cooling circuit in order to cool the internal combustion engine, others include a cooling circuit for certain equipment on board the vehicle, such as for example an EGR, the acronym of an exhaust gas recirculation device, or an additional thruster of the electric motor type, still others include an air conditioning circuit. There are also vehicles that, cumulatively, include each of these circuits.
    In addition, there are different heat exchanger beams so that depending on the need for cooling, the design of the heat exchangers varies from one heat exchanger to another, so that there is a great diversity of design of the heat exchanger modules. heat exchange.
    Most of the time, the cooling radiator is common to several engines, which is not the case for other heat exchangers, such as the condenser of an air conditioning loop or the radiator arranged in a cooling circuit at low temperature.
    It is known to form a heat exchange assembly or module disposed at the front of the vehicle, comprising a low temperature heat exchanger, an air conditioning condenser and an engine cooling radiator, sometimes referred to as a heat exchanger. high temperature, preferably arranged in this order relative to the direction of flow of air during the movement of the vehicle.
    Each variant of a module has the disadvantage of including its own means for attaching the heat exchangers to each other, which is contrary to a need for standardization. Indeed, among the various fixing means, it is known those consisting of a screw connection, which requires a long operation for mass production of motor vehicles equipped with such heat exchange modules. The manufacturing costs are therefore increased.
    OBJECT OF THE INVENTION The object of the invention is to remedy all of the aforementioned drawbacks and relates to a heat exchange module comprising a radiator and at least one functional element mutually connected to one another by means of a heat exchanger. intermediate fixing means such that the functional element extends in a plane parallel to the radiator beam, which defines a plane of axes Y and Z, an axis X being perpendicular to the plane of the radiator beam, the radiator and the functional element being intended to be traversed by a flow of air.

    Such a heat exchange module has the advantage of allowing improved management of the diversity of modules, while remaining simple and inexpensive design to implement.

    Description of particular embodiments
    In the following description, identical or similar elements will bear the same numbers and reference numbers. Expressions such as "back" and "front", "left" and "right", "upper" and "lower" and "longitudinal", "transverse" and "vertical" orientations will respectively be defined with reference to the X triad, Y, Z and the definitions given in the description. In particular, the longitudinal direction X corresponds to the direction of travel in the forward direction of a motor vehicle (not shown in the figures), which also corresponds to the direction of flow of the cooling air through the heat exchange module of the invention.
    With reference to the figures, the heat exchange module 1 according to the invention aims to propose a new method of manufacturing and assembling a cooling radiator of a coolant with a functional element 3, 4 which can to be of different designs, as will be detailed in what follows.
    Advantageously, such a module 1 allows easy assembly of the radiator 2A, 2B with a functional element and comprises for this purpose fixing means for fixing said functional element substantially parallel to the beam of the radiator 2A, 2B.
    With reference to FIG. 1, the heat exchange module 1 consists of a stack of heat exchangers cooled by an X-direction airflow. The stack of the heat exchangers with respect to the direction of flow of the cooling air, is performed by a radiator 2B to be traversed by a coolant at low temperature, a condenser 5 through which a refrigerant is intended to flow and a radiator 2A cooling a heat transfer fluid at high temperature, arranged in this order.
    While the beam of the condenser 5 covers almost all of the beam of the radiator 2A on which it is mounted, the radiator 2B comprises a beam of smaller size. However, depending on the need for cooling, the beam of the radiator 2B may be of different size in order to cover the beam of the radiator 2A differently.
    The radiator 3 may be traversed by a heat transfer fluid flowing through a cooling circuit in which a recycled exhaust cooling heat exchanger or any other equipment requiring cooling, such as an electric motor, can be arranged. driving the vehicle in the case of a hybrid vehicle, its electric power charging device and / or its control device.
    The condenser 5 can be arranged in an air conditioning circuit for regulating the temperature inside the passenger compartment of the vehicle.
    The radiator 2A is intended to be connected to a cooling circuit of the internal combustion engine.
    Depending on the vehicle equipped with the heat exchange module 1, the cooling requirements vary according to the type of engine, the volume of the cabin to be air-conditioned, and the equipment to be cooled.
    In order to promote the assembly of the radiator 2A or 2B with different functional elements 3 or 4, the fixing means of the module 1 of the invention comprise an assembly device 20 of the radiator to the functional element 3, 4 by the one end of the radiator beam and an indexing and locking device 30 located at the other end of the beam.
    With reference to FIG. 3, the assembly device 20 described below allows the connection between the radiator 2A inside which a high temperature cooling fluid circulates and a radiator 3 inside which circulates a fluid of cooling at low temperature. By way of nonlimiting example, the temperature of a high-temperature cooling fluid is between 80 ° C. and 115 ° C. while the temperature of a low-temperature cooling fluid is between 40 ° C. and 60 ° C. ° C.
    The assembly device 20 is partly formed by fingers 23 projecting out of the radiator 3. Each finger 23 is parallel to the radiator beam 3 and made by molding the manifold of the radiator 3. The finger 23 is arranged in the vicinity of an inlet or outlet pipe of the coolant in the manifold of the radiator 3.
    In order to operate the assembly of the radiator 2A with the secondary radiator 2B, the finger 23 is disposed in abutment against abutments Z and X axes which are formed in bridges 24 belonging to the radiator 2. The collector boxes of the radiator 2A are of substantially vertical orientation and parallel to each other. One of these manifolds comprises said bridges 24.
    These can be made by molding the manifold of the radiator 2.
    Preferably one of the manifolds of the radiator comprises two bridges 24 which are parallel to each other, one being an upper bridge and the other a lower bridge.
    Here, the upper bridge 24 bypasses a bottle 7 for storing a refrigerant fluid connected to the collector of the condenser 5. For this purpose, the upper bridge 24 comprises an arm of substantially arcuate section, the concave face of which faces the the bottle 7. The free end of the bridge 24 comprises a passage extending transversely through the arm. The passage is thus delimited by the stops 21 and 22 of Z and X axes and is shaped to receive the upper finger 23 of the radiator 2B.
    The lower bridge 24 extends directly under the bottle 7 of the condenser 5. Such an architecture allows compactness in X of the stack of exchangers forming said module 1 of the invention. Thus the secondary radiator 2B is disposed as close to the radiator 2A.
    The bridge 24 comprises a straight arm X axis at the end of which is formed a passage of Y axis. The passage is delimited by the stops 21 and 22 axes Z and X and is shaped to receive the finger 23. lower radiator 2B.
    When the secondary radiator 2B is connected to the radiator 2A by the connecting device 20, the fingers 23 can pivot inside the passages of the jumpers 24, which makes possible the angular displacement of the secondary radiator Z of the Z axis with respect to one of the collector boxes of the radiator 2A. The secondary radiator 2B is also able to move in a plane substantially parallel to the radiator beam 2A.
    According to the embodiment of Figure 4, the module 1 comprises an assembly device 20 which allows the connection between the secondary radiator 2B and a protective grid 4 also called anti-gravel grid. Such a grid is disposed upstream of the heat exchange module 1, according to the direction of flow of the air, more particularly with respect to a secondary radiator 2B.
    The secondary radiator 2B may be a mechanical radiator for which the assembly of tubes, fins, collector plates and closure covers is made by crimping.
    Alternatively, the secondary radiator 2B may be a brazed radiator for which the assembly of the tubes, fins, collector plates and closure covers is carried out by brazing.
    The assembly device 20 is partly formed by fingers 23 projecting out of the radiator 3. Each finger 23 is parallel to the grid 4 and made by overmolding the grid 4.
    In order to operate the assembly of the grid 4 with the secondary radiator 2B, the finger 23 is disposed in abutment against abutments Z and X axes which are formed in bridges 24 belonging to the radiator 2B. The collector boxes of the radiator 2B are of a substantially vertical orientation and parallel to each other, and include said bridges 24. These can be made by molding the manifold of the radiator 2B.
    Preferably one of the manifolds of the radiator 2B comprises two bridges 24 which are parallel to each other.
    Each bridge 24 protrudes out of the collector box of the radiator 2B along the axis X. The free end of each bridge 24 protruding comprises a passage extending transversely through the arm. The Y-axis passage is thus delimited by the stops 21 and 22 of Z and X axes and is shaped to receive the finger 23 of the grid 4.
    When the secondary grid 4 is connected to the secondary radiator 2B by the assembly device 20, the fingers 23 can pivot inside the passages of the bridges 24, which makes possible the angular displacement of the axis Z of the grid 4 relative to at one of the manifolds of the secondary radiator 2B. The gate 4 is also able to move in a plane substantially parallel to the beam of the secondary radiator 2B.
    By the opposite manifold of the radiator 2A or the secondary radiator 2B, the heat exchange module 1 comprises an indexing and locking device 30 which will now be detailed.
    The indexing and locking device 30 is visible on the left-hand part of the heat exchange module 1, at the level of the dashed-circled zone in FIG. 1 which is enlarged in FIG. to pre-position the secondary radiator 2B with respect to the radiator 2A along the Y and Z axes. For this purpose, the secondary radiator 2B comprises an attachment interface 33 which is in the form of a plate projecting out of of the manifold, substantially parallel to the beam of the radiator 2B. The fixing interface 33 can be made by molding the plastic collecting box. The attachment interface 33 includes openings through which indexing fingers can extend.
    An indexing pin 31 makes it possible to position the secondary radiator 2B in Z relative to the radiator 2A.
    An indexing pin 32 makes it possible to position in Y the secondary radiator 2B relative to the radiator 2A.
    Each pin 31 or 32 indexing is made by molding the cover of the collector box 2A radiator, so that it extends perpendicular to the beam.
    To facilitate the insertion of the pins 31 and 32 for indexing the radiator 2A in the openings of the interface 33 of the secondary radiator 2B, each free end of the pins 31 and 32 is conical.
    As can be seen in FIG. 2, the indexing and locking device 30 further comprises means for holding the secondary radiator 2B on the radiator 2A relative to the axis X.
    Said holding means is formed in part by an abutment 35 support X against which the inner face of the interface 33 is arranged in support.
    Said holding means is also formed by tabs 34 deformable at the end of each of which is arranged a hook for engaging an edge of the interface 33 fixing. A lower tongue 34 is attached under the attachment interface 33 so that its hook engages a lower edge of said interface. An upper tongue 34 engages with a vertical edge formed in a notch made in the upper part of the interface 33 fixing.
    Advantageously, each indexing pin 31 and 32 is a tube inside which a screw can be arranged so that in the event of rupture of a deformable tongue 34, the fixation of the secondary radiator 2B on the radiator 2A is made by screwing.
    As can be seen in FIG. 5, the radiator 2A can comprise several X-holding means in order to respond favorably to the need for diversity of the exchangers. For example, the radiator 2A comprises tabs 34 lower, intermediate and upper. This enables the radiator 2A to be connected to a radiator 2B having a beam of height h1 by the use of the lower and intermediate tabs 34 as shown in FIG. 1. According to another configuration of the heat exchange module 1, this allows to assemble the radiator 2A a radiator 2B having a beam of height h2 greater than the height h1 by the use of the tabs 34 lower and upper as shown in Figure 5. Such a radiator 2A can manage the design diversity heat exchange modules 1.
    In FIG. 4, the device 30 for indexing and blocking the gate 4 to the secondary radiator 2B takes up the same attachment principle as previously described.
    An attachment interface 33 extends transversely in the plane of the grid and comprises an opening in which is disposed an indexing pin ensuring its positioning in Y and Z relative to the secondary radiator 2B.
    Said X holding means are formed by deformable tongues and provided with hooks. Here a lower tab cooperates with the lower side edge of the attachment interface while an upper tab cooperates with an opening whose edge is engaged with its hook.
    Each tongue allows retention in -X according to a principle of fast fastening type by clipping.
    An abutment in X allows a support of the fixing interface of the grid.
    The abutment, the tongues and the pins came from molding a plastic material of the collector box of the secondary radiator 2B.
    Due to manufacturing tolerances of said X-holding means, the heat exchange module 1 comprises means for stressing the secondary radiator 2B against the radiator 2A or the gate 4 against the secondary radiator 2B, or cumulatively both. .
    Said stressing means is formed of at least one flexible tongue disposed respectively projecting on at least one of the radiator 2A and the radiator 2B, and one of the radiator 2B and the grid 4 .
    With the fixing means as previously described, the secondary radiator 2B and the protective grid 4 can be easily assembled respectively to the radiator 2A and the secondary radiator 2B, so that the manufacturing time of a heat exchange module 1 according to the invention is reduced while ensuring a quality of assembly.
    After having used the assembly device present at a collector box of the radiator 2A or the secondary radiator 2B, the rotational movement along the axis Z of the radiator 2B towards the radiator 2A makes it possible to engage the pins 31 and 32 indexing in the dedicated openings made in the interface 33 fixing until the clipping of the latter. This same procedure can be followed for fixing the gate 4 on the secondary radiator 2B.
    Advantageously, the heat exchange module 1 made with such a fixing means 10 makes it possible to design modules varying according to the radiator beam 2B (height h1 or height h2), depending on the presence of the grid 4.
    The heat exchange module 1 can equip vehicles of different designs as to their drive engine or equipment to be cooled.
    For this reason, the invention also relates to a vehicle equipped with such a structural element.
