Definitions
- the invention relates to air/air type radiator heat exchange systems.
- air/air type radiator heat exchange systems are used.
- this type of heat exchange system can be part of a cooling and/or heating circuit.
- a heat exchange system can be part of a cooling circuit of an engine of the powertrain (or GMP).
- the radiator is supplied with air by an air conveyor with the interposition of an interface piece (sometimes called an “exchanger”). More specifically, the radiator comprises a first inlet face capable of receiving air, and the interface part comprises a second inlet face capable of receiving air (coming from the air conveyor) and a first outlet face coupled to the first inlet face of the radiator to supply it with air.
- an interface piece sometimes called an “exchanger”. More specifically, the radiator comprises a first inlet face capable of receiving air, and the interface part comprises a second inlet face capable of receiving air (coming from the air conveyor) and a first outlet face coupled to the first inlet face of the radiator to supply it with air.
- the aim of the invention is therefore in particular to improve the situation.
- a heat exchange system comprising a radiator of the air/air type and comprising a first inlet face capable of receiving air, and an interface part comprising a second inlet face capable of receiving air to be transferred and a first outlet face coupled to the first inlet face to supply it with transferred air.
- radiator comprises on each of the first two parallel edges of its first inlet face two first parallel ribs
- This interlocking over the entire length of the first and second edges on two sides of the system advantageously makes it possible to obtain quality double baffle airtightness that withstands high temperatures, without the need to use an elastomer foam.
- the heat exchange system according to the invention may comprise other characteristics which may be taken separately or in combination, and in particular:
- the first ribs of each of the two first edges can delimit a first housing
- the second ribs of each of the two second edges can delimit a second housing housing one of the corresponding first ribs and one of them is housed in the first corresponding housing, so as to achieve nesting
- - its interface piece may comprise on a third edge, perpendicular to the second edges and delimiting the first outlet face, an extension defining a recess and partially covering part of a face of the radiator, perpendicular to the first inlet face , in order to contribute to sealing;
- its radiator can comprise on its first edges, at the level of a first end part, two third housings.
- its interface part may comprise on its second edges, at a first end part, two coupling lugs housed at least partially and respectively in the third housings in order to couple the first output face to the first entry face;
- its radiator may comprise on at least one of its first edges, at the level of a second end part opposite its first end part, a threaded hole.
- its interface piece may comprise on at least one of its second edges, at a second end part opposite its first end part, a fixing lug provided with a hole crossing crossed by a screw screwed into the threaded hole in order to ensure the fixed connection of the interface part to the radiator;
- an air conveyor comprising a third inlet face capable of receiving the air and a second outlet face coupled to the second inlet face to supply it with air conveyed from the third face of the entry for transfer to radiator;
- the second exit side can be coupled to the second entry side by clipping.
- the invention also proposes a vehicle, optionally of the automobile type, and comprising a cooling and/or heating circuit comprising at least one heat exchange system of the type presented above.
- FIG. 1 schematically illustrates, in a perspective view, an embodiment of a heat exchange system according to the invention, during assembly
- FIG. 2 schematically illustrates, in a view from below, the heat exchange system of Figure 1, once assembled,
- FIG. 3 schematically illustrates, in a sectional view in a horizontal plane, the overlap between the first ribs of a first edge of the radiator of FIG. 2 and the second ribs of a second edge of the interface part of the figure 2,
- FIG. 4 schematically illustrates, in a sectional view in a vertical plane, the positioning of the extension of the third edge of the interface part of figure 2 with respect to the face of the radiator of figure 2, and
- FIG. 5 schematically illustrates, in a front view from the side of the second inlet face of the interface part, the heat exchange system of FIG. 2, without its air conveyor.
- the object of the invention is in particular to propose a heat exchange system SE in which the seal between the first inlet face FE1 of the radiator RA and the first outlet face FS1 of the interface part PI is ensured in particular by nesting of ribs N1 and N2.
- the heat exchange system SE according to the invention is intended to be part of a cooling and/or heating circuit. But the invention is not limited to this application. Indeed, an SE heat exchange system according to the invention can be an independent piece of equipment responsible for heating and/or cooling air.
- the cooling and/or heating circuit is intended to cool (and possibly heat) an engine of a powertrain (or GMP). But the invention is not limited to this application.
- the cooling and/or heating circuit is intended to equip a vehicle of the automotive type, such as a car for example. But the invention is not limited to this application. Indeed, the circuit can equip any vehicle (land, sea (or river), or air), any installation (possibly industrial), and any building.
- a heat exchange system SE comprises at least one radiator RA and an interface part (or exchanger) PL
- the radiator RA is of the air/air type and comprises a first inlet face FE1 which is capable of receiving air from the interface part PI. In addition, it comprises two first edges B1 parallel to each other, participating in the delimitation of its first entry face FE1, and on each of which are defined two first ribs N1 parallel to each other (see figures 2 and 3).
- the PI interface part comprises a second inlet face FE2 which is capable of receiving air to be transferred to the first inlet face FE1 of the radiator RA, and a first outlet face FS1 which is coupled to this first inlet face FE1 to supply it with air transferred from the second inlet face FE2.
- the term “nesting” means that the first N1 and second N2 ribs of the first B1 and second B2 edges which correspond are substantially parallel to each other, being intercalated and partially overlapping according to a sequence of the type (N1, N2, N1 , N2) which makes it possible to define a kind of double baffle, as illustrated in figure 3.
- the first ribs N1 of each of the first two edges B1 can delimit a first housing L1
- the second ribs N2 of each of the two second edges B2 can delimit a second housing L2 which houses one of the corresponding first ribs N1, while at the same time one of these second ribs N2 is housed in the corresponding first housing L1.
- the PI interface part may include a third edge B3, perpendicular to its second edges B2 and delimiting the first output face FS1 (here in its upper part) .
- This third edge B3 comprises an extension EB which defines a recess DE and which partially covers part of the face (here upper) FR of the radiator RA, which is perpendicular to the first inlet face FE1, in order to participate in the sealing in the air.
- this recess DE (here upwards) allows the extension EB to reach the first inlet face FE1 of the radiator RA a little below the upper face FR, then to partially cover this upper face FR (by forming a kind of "cap”).
- the recess DE defines a kind of "chicane” which makes it possible to very significantly reduce the quantity of air that can exit through the third edge B3 of the interface part PI, at the interface with the first face input FE1 of the radiator RA.
- the radiator RA may comprise on its first two edges B1, at the level of a first end part PE11 (here lower), two third L3 slots.
- the PI interface part may comprise on its second edges B2, at a first end part PE12 (here lower), two PC coupling tabs which are housed at least partially and respectively in the third housings L3 in order to couple the first output face FS1 to the first input face FE1 and therefore the interface part PI to the radiator RA.
- Such an arrangement is particularly advantageous when assembling the system SE because it makes it possible to start by partially introducing the two PC coupling lugs into the third housings L3 by a small translation at an angle (here from top to bottom), then rotating the PI interface part towards the first inlet face FE1 of the radiator RA in order to nest the first N1 and second N2 ribs of the first B1 and second B2 edges which correspond.
- the interface part PI is slightly translated with respect to the radiator RA (here downwards), in order to complete the introduction of the two coupling legs PC into their third housings L3 and to place the free end part of the extension EB of the third edge B3 on the upper face FR of the radiator RA (if possible in contact to optimize sealing, but without exerting pressure when the radiator RA comprises fragile fins (for example aluminum)).
- the result of the partial introduction of the two coupling tabs PC into the two third housings L3 is illustrated in figure 1 .
- the radiator RA can also comprise on at least one of its first edges B1, at the level of a second end part PE21 (here upper) opposite its first end part PE11 (here lower), a threaded hole TF.
- the PI interface part can comprise on at least one of its second edges B2, at the level of a second end part PE22 (here upper) opposite to its first end part PE12 (here bottom), a fixing bracket PF provided with a through hole TT.
- the through hole TT can be crossed by a screw which is screwed into the threaded hole TF of the radiator RA in order to ensure the fixed attachment of the interface part PI to the radiator RA, and to participate in the sealing due to of the veneer generated by the screwing. It will be understood that this screwing is carried out once that the PI interface part has been correctly and fully positioned with respect to the RA radiator (and therefore here after the rotation drive and the final downward translation).
- the fixed attachment of the interface part PI to the radiator RA could be done by clipping thanks to first and second clipping means cooperating together and defined respectively on the interface part PI and the radiator AR.
- the system SE can also comprise an air conveyor CA comprising a third inlet face FE3, capable of receiving the air (intended for the radiator RA via the interface part PI), and a second output face FS2, coupled to the second input face FE2 to supply it with air conveyed from the third input face FE3 with a view to its transfer to the radiator RA.
- an air conveyor CA comprising a third inlet face FE3, capable of receiving the air (intended for the radiator RA via the interface part PI), and a second output face FS2, coupled to the second input face FE2 to supply it with air conveyed from the third input face FE3 with a view to its transfer to the radiator RA.
- the second output face FS2 of the air conveyor CA can be coupled to the second input face FE2 of the interface part PI by clipping.
- the PI interface part may comprise first clipping means distributed over its periphery (for example clipping lugs) and cooperating with corresponding second clipping means and defined on the periphery of the second output face FS2 of the AC air conveyor (e.g. through holes).
- the fixed attachment of the air conveyor CA to the interface part PI could be done by screwing.
- the interface part PI and/or the air conveyor CA can be made by molding a plastic or synthetic material.
- PA6 GF35 Polyamide 6 filled with 35% glass fibers
