Definitions
- the present invention relates to the field of heat exchangers, and more particularly to such heat exchangers equipped with an exchange bundle formed by a stack of plates.
- Such heat exchangers are intended, for example, to equip vehicles, and in particular motor vehicles. Within such vehicles, these heat exchangers ensure the thermal regulation of a first fluid, such as an air flow, circulating through the heat exchanger in a dedicated circulation space by a second fluid, such as 'a cooling liquid, circulating in dedicated channels within the heat exchanger.
- a first fluid such as an air flow
- a second fluid such as 'a cooling liquid
- turbochargers to increase the power of the thermal engine of said vehicles.
- These turbochargers direct a flow of air towards an intake manifold and compress it before this air flow reaches the combustion chamber. This flow of air, commonly called “charge air”, allows the engine to be supercharged, allowing it to achieve better fuel combustion.
- heat exchangers intended to cool the air flow or “charge air” to increase the density of the intake air of the turbocharged engine.
- These heat exchangers also called “charge air coolers”, generally comprise an exchange bundle formed by a stack of plates between which the charge air flow circulates. This stack of plates is traversed by a fluid communicating with each of the plates via channels provided within said plates. An exchange of calories being able to take place between the plates, or, where appropriate, between radiant elements arranged between two adjacent plates, and the flow of supercharge air.
- Such an exchange harness is housed in a housing surrounding the exchange harness.
- This housing is generally formed of four pieces forming cheeks joined to each other to form a parallelepiped enclosing the exchange beam, two opposite faces of this parallelepiped, distinct from the cheeks, being open and intended to be crossed by the flow of charge air.
- the cheeks are joined to each other by brazing their ends placed end to end.
- Such a solution tends to suffer wear over time at the level of these brazings. This wear can result, under the effect of the pressure of the charge air circulating through the heat exchanger, in an opening through which the charge air flow can escape, reducing the efficiency of the turbocharger for increase the power of the heat engine.
- the present invention aims to overcome the drawbacks of the prior art, and in particular to limit the formation of openings at the brazing points joining two sides of the housing.
- the present invention also aims to improve the mechanical resistance of the cheeks to the pressure exerted by the charge air flow and to make the brazing making it possible to form the housing more resistant.
- the main object of the present invention is a heat exchanger comprising an exchange bundle intended to be traversed by a heat transfer liquid and by a gas flow, the exchange bundle comprising a plurality of plates stacked one on top of the other. the others along a stacking direction and delimiting between at least two adjacent plates at least one circulation conduit for the heat transfer liquid, each circulation conduit communicating through a first end with a first channel of the exchange bundle and through a second end with a second channel of the exchange bundle, the heat exchanger comprising a housing surrounding the exchange bundle and comprising at least one upper cheek, a lower cheek and at least one main side cheek, the main side cheek being arranged in continuity with the upper cheek and/or the lower cheek, characterized in that the housing comprises at least one intermediate side cheek interposed between the beam of exchange and the main side cheek.
- the heat exchanger housing partially surrounds the exchange core.
- This box is a parallelepiped open on two opposite faces allowing the gas flow to circulate through the exchange beam.
- the four other faces, forming the different cheeks of said parallelepiped, are formed by the main side cheeks, the upper cheek and the lower cheek.
- the circulation conduit through which a heat transfer fluid circulates within the exchange bundle is delimited by a pair of plates, between each pair of plates the exchange bundle comprises a circulation space in which heat dissipation means are provided.
- These heat dissipation means are formed by fins making it possible to increase the exchange surface between the heat exchanger and the gas flow.
- the main side cheek is arranged in continuity with the upper cheek and the lower cheek so that the housing is airtight at the junction between these cheeks. More precisely, the main side cheek is arranged in continuity with the upper cheek and the lower cheek by an alignment of the internal surface of each of these cheeks, this internal surface being the surface of said cheeks intended to be facing the beam of 'exchange.
- the first channel and the second channel are formed by stacking the plates in a stacking direction. These channels are formed by stacking the plates, more precisely, at the level of each of the plates a collar is provided allowing a channel to be formed. It is understood that each of the plates comprises two collars allowing, when the plates are stacked on top of each other, to form the first channel and the second channel.
- the intermediate side cheek has a dimension greater than a dimension of the main side cheek against which said intermediate side cheek bears, these dimensions being measured parallel to the stacking direction. It is understood that the intermediate side cheek extends beyond the main side cheek in a direction parallel to the direction of stacking of the plates. It should be noted that the intermediate side cheek rests against the main side cheek so that these side cheeks are pressed against each other.
- the housing has at least one junction zone between at least one main side cheek and the upper cheek and/or the lower cheek, the intermediate side cheek extending along the main side cheek, the lower cheek and/or the upper cheek and said junction zone. It is understood that the intermediate side cheek completely covers the junction between the main side cheek and the lower cheek and/or the upper cheek. This covering of the junction between these cheeks forms a physical barrier protecting the junction between the main side cheek and the upper cheek and/or the lower cheek.
- the junction zone comprises at least a first brazing between the intermediate side cheek and the upper cheek and/or the lower cheek, the junction zone comprising a second brazing between the intermediate side cheek and the cheek main side, the junction zone comprising a third brazing between the main side cheek and the upper cheek and/or the lower cheek.
- the third brazing is an edge-to-edge brazing between the main side cheek and the lower cheek and/or the upper cheek. This edge-to-edge brazing makes it possible to align the main side cheek in continuity with the upper cheek and/or the lower cheek.
- the housing comprises a means of pre-assembly between the intermediate side cheek and the main side cheek against which said intermediate side cheek bears.
- a pre-assembly means advantageously allows, when assembling the heat exchanger, to assemble the main side cheek and the intermediate side cheek at the same time. It is further understood that the pre-assembly means ensures that each of said cheeks is positioned precisely relative to the other.
- the pre-assembly means comprises cooperation between at least one projecting element and a hole, the projecting element coming from one of the side cheeks and the hole is provided in the other cheek lateral.
- the protruding element and the hole can be provided on any of the intermediate or main side cheeks as long as the protruding element is provided on one of the side cheeks and the hole on the other.
- the intermediate side cheek comprises a first edge in contact with the upper cheek and a second edge in contact with the lower cheek.
- the upper cheek and/or the lower cheek comprises at least one edge provided with a fillet, the first edge and/or the second edge of the intermediate side cheek having a rounding complementary to the fillet. It is understood that the first edge and/or the second edge have a shape allowing the main side cheek to fit the upper cheek and/or the lower cheek.
- the housing comprises two intermediate side cheeks, each being associated with a main side cheek.

- characteristics, variants and different embodiments of the invention can be associated with each other, in various combinations, to the extent that they are not incompatible or exclusive of each other. It will be possible in particular to imagine variants of the invention comprising only a selection of characteristics described subsequently in isolation from the other characteristics described, if this selection of characteristics is sufficient to confer a technical advantage or to differentiate the invention from to the state of the art.
- Figure 1 represents a heat exchanger 1 intended to be traversed by a gas flow.
- this gas flow is a flow of compressed air upstream of the heat exchanger 1, that is to say before entering the heat exchanger 1, by a turbocharger and intended for be sent to an intake manifold of a heat engine at the outlet of the heat exchanger i.
- the heat exchanger i comprises an exchange bundle 2 formed of a plurality of plates 21 stacked one on top of the other along a stacking direction A substantially parallel to the axis V.
- Each of the plates 21 s extends in a direction of main longitudinal elongation, substantially parallel to the axis L. It is understood that the plates 21 are stacked on top of each other in a direction perpendicular to their direction of main longitudinal elongation.
- the exchange bundle 2 is housed in a housing 3, as visible in sectional view, isolated from the other elements of the heat exchanger 1, in Figure 4, comprising an upper cheek 31, a lower cheek 32 opposite to the upper cheek 31 and at least one main side cheek 33.
- the at least one main side cheek 33 is arranged in continuity with the upper cheek 31 and the lower cheek 32.
- the housing 3 comprises two main side cheeks 33 distributed at each longitudinal end of the plates 21, that is to say on either side of the exchange beam 2 according to the direction of main longitudinal elongation of the plates 21. It is understood that the housing 3 surrounds, at least partially, the exchange beam 2 and forms a parallelepiped of which four faces are formed by the upper cheek 31, the lower cheek 32 and the two main side cheeks 33.
- two opposite faces are open and allow the air flow to circulate through the exchange beam 2.
- These two opposite open faces are, each, connected to an arch 34 by which the air flow is directed so as to circulate through the exchange beam 2.
- the exchange bundle 2 is intended to carry a heat transfer liquid capable of carrying out a heat exchange with the air flow.
- the cheek upper 31 comprises an inlet opening 311 for the heat transfer liquid through which the heat transfer liquid is able to enter the exchange bundle 2.
- This inlet opening 311 is connected to a first channel 22 provided in the exchange bundle 2 according to the stacking direction A of the plates 21.
- the upper cheek 31 comprises an outlet opening 312 for the heat transfer liquid through which the heat transfer liquid is capable of leaving the exchange bundle 2.
- This outlet opening 312 is connected to a second channel 23 which, like the first channel 22, is provided in the exchange bundle 2 in the stacking direction A of the plates 21.
- This circulation conduit 24 communicates via a first end or inlet end 241 with the first channel 22 and via a second end or outlet end 242 with the second channel 23. It is understood that the heat transfer liquid entering the heat exchanger 1 through the inlet opening 311 of the upper cheek 31 circulates in the exchange bundle 2 via the first channel 22 and is distributed in each circulation conduit 24 formed between two adjacent plates 21. The heat transfer liquid circulates from the inlet end 241 of the circulation conduit 24 to the outlet end 242 of said circulation conduit 24 communicating with the second channel 23 connected with the outlet opening 312 of the upper cheek 31 by which the heat transfer liquid is able to leave the heat exchanger 1.
- the housing 3 comprises, according to the invention, at least one intermediate side cheek 35 interposed between the exchange beam 2 and the at least one main side cheek 33.
- the housing 3 comprises two main side cheeks 33 each being associated with an intermediate side cheek 35 interposed between one of the main side cheeks 33 and the exchange beam 2.
- a cooperation formed by a pre-assembly means 4 allows the main side cheek 33 to be positioned relative to the intermediate side cheek 35.
- Figure 2 illustrates a view of the exchange beam 2 in the transverse direction, that is to say in a direction parallel to the axis T.
- the exchange beam 2 comprises a plurality of plates 21 stacked on top of each other in the stacking direction A. Two adjacent plates 21, delimiting between them a circulation conduit 24, are separated from two other plates 21, also delimiting a circulation conduit 24, by a circulation space 25 for the gas flow.
- This circulation space 25 is, in the embodiment shown, partially filled by radiant elements 26.
- the radiant elements 26 are formed by a corrugated sheet extending mainly in the longitudinal direction L, that is to say along the axis L, substantially parallel to the plates 21.
- an exchange of calories takes place between the metal wall, forming the radiant elements 26, and the air flow such that the calories of the metal wall are exchanged with the heat transfer liquid circulating in the circulation conduit 24 delimited between two adjacent plates 21.
- the shape of the radiant elements 26 makes it possible to increase the exchange surface between the metal wall and the air flow.
- the radiant elements 26 can take other shapes as long as these shapes make it possible to increase the exchange surface between the metal wall and the air flow and therefore to increase the number of calories able to be transmitted to the heat transfer liquid.
- the exchange beam 2 comprises two intermediate side cheeks 35, each being associated with a main side cheek 33.
- These intermediate side cheeks 35 extend in a vertical direction, that is to say parallel to the stacking direction A, over the entire height of the exchange beam 2, the height being defined as the elongation dimension of the object concerned in a vertical direction, parallel to the V axis.
- these intermediate side cheeks 35 have an internal face 351 intended to face the exchange beam 2 and an external face 352, opposite the internal face 351, intended to face, at least in part, an associated main side cheek 33.
- Each of the main side cheeks 33 is arranged in continuity with the lower cheek 32 and/or the upper cheek 31.
- the lower and upper cheeks 31 and 32 extending, in the embodiment shown, according to a main longitudinal direction of elongation between a first longitudinal end 36 and a second longitudinal end 37, have at least one edge forming a fillet 38 allowing the first and second longitudinal ends 36 and 37 to extend in a vertical direction, perpendicular to the stacking direction A.
- a fillet 38 allows the main side cheeks 33 to be arranged in continuity with the upper cheek 31 and the lower cheek 32.
- the intermediate side cheeks 35 are in contact with the upper and lower cheeks 31 and 32 and more particularly, at the level of the fillet 38. As visible in Figure 5, the portion of the intermediate side cheeks 35 in contact with the upper and lower cheeks 31 and 32 at the level of the fillet 38 has a shape complementary to the fillet 38. More precisely, each intermediate side cheek 35 comprises a first edge 353 forming a rounding having a shape complementary to the fillet 38 of the upper cheek 31 and intended to be in contact with this last. Each intermediate side cheek 35 also comprises a second edge 354, opposite the first edge 353, forming a rounding having a shape complementary to the fillet 38 of the lower cheek 32 and intended to be in contact with the latter.
- each intermediate side cheek 35 extends beyond the associated main side cheek 33 along a vertical dimension, measured parallel to the stacking axis A.
- the intermediate side cheek 35 has a dimension greater in the stacking direction A of the plates 21 than a dimension of the main side cheek 33 against which said side cheek intermediate 35 takes support.
- Figure 3 illustrates an intermediate side cheek 35 and a main side cheek 33 against which the intermediate side cheek 35 bears.
- the housing 3, and more particularly the main side cheek 33 and the intermediate side cheek 35, has a pre-assembly means 4.
- This pre-assembly means 4 is formed by the cooperation between at least one hole and a projecting element. More precisely, in the embodiment shown, the preassembly means 4 is formed by the cooperation between two holes 41 provided in the main side cheek 33 and two elements projecting 42 from the intermediate side cheek 35.
- a projecting element 42 of the intermediate side cheek 35 is intended to be housed in a hole 41 of the main side cheek 33.
- the holes 41 advantageously have a round shape complementary to the shape of the projecting elements 42 and whose diameter is substantially equal to the diameter of the projecting elements 42.
- the pre-assembly means 4 advantageously allows the intermediate side cheek 35 to be precisely positioned against the main side cheek 33. It is understood that the pre-assembly means 4 comprising two holes 41 cooperating with two projecting elements 42 advantageously allows , to block a movement of one of the lateral faces 33, 35 relative to the other in, on the one hand, a direction parallel to the axis L and on the other hand, a direction parallel to the axis V.
- the projecting elements 42 extend from the external face 352 of the intermediate side cheek 35 towards the main side cheek 33.
- these projecting elements 42 can extend from any of the side cheeks 33' 35 towards the associated side cheek 33, 35 comprising holes 41 capable of receiving the projecting elements 42.
- Figure 4 schematically illustrates a sectional view of the housing 3 isolated from the heat exchanger 1. More particularly, Figure 4 illustrates junction zones 5 at the level of which the intermediate side cheek 35, the main side cheek 33 and the cheek upper 31 and/or the lower cheek 32 are secured to each other. These junction zones 5 are located at the level of the first and second longitudinal ends 36 and 37 of the upper cheek 31 and the lower cheek 32.
- the main side cheek 33 is arranged in continuity with the lower cheek 32 and the upper cheek 31.
- This arrangement is such that the face of the main side cheek 33, intended to be in contact with the intermediate side cheek 35, is in continuity with the face of the lower cheek 32 or the upper cheek 31, intended to be in contact with the intermediate side cheek 35, and more particularly the internal face 352 of this intermediate side cheek 35.
- junction between the main side cheek 33 and the upper cheek 31 or the lower cheek 32 makes it possible to form a smooth surface against which the external face 352 of the intermediate side cheek 35 bears.
- the main side cheek 33, the intermediate side cheek 35 and the lower cheek 32 or the upper cheek 31 are brazed against each other by a brazing process at very high temperature.
- Figure 5 illustrates a junction zone 5 between the main side cheek 33, the associated intermediate side cheek 35 and the lower cheek 32. More precisely, Figure 5 illustrates an exploded view of said junction zone 5, in which the side cheek intermediate 35, the main side cheek 33 and the lower cheek 32 are separated from each other. It should be noted that the description which follows in connection with a junction zone 5 of the housing 3, applies mutatis mutandis to each junction zone 5 of the housing 3.
- the brazing of the intermediate side cheek 35, the main side cheek 33 and the lower cheek 32 is carried out by heating at high temperature a coating interposed between two of said cheeks 33, 35, 32.
- the junction zone 5 comprises a first covering 51 disposed between the intermediate side cheek 35 and the main side cheek 33 and a second covering 52 disposed between the lower cheek 32 and the intermediate side cheek 35.
- Figure 5 illustrates a junction zone 5 before the housing 3 has been heated to a very high temperature.
- a third coating 53 is formed by migration, in particular of a part of the first and second coatings 51, 52, said third coating 53 being arranged between the main cheek 33 and the lower cheek 32.
- Each of the coverings 51, 52 and 53 then forms a polymerized layer secured between two adjacent cheeks.
- the fusion of the sacrificial layers which are the first coating 51 and the second coating 52, the formation of the third coating 53 and the mixing of said first, second and third coatings 51, 52, 53, ensure the joining of the parts concerned, once cooled.
- the first covering 51 is arranged so as to be in contact with the external face 352 of the intermediate side cheek 35 and the face of the main side cheek 33 facing the external face 352 of the intermediate side cheek 35.
- the second covering 52 is arranged at the level of the first longitudinal end 36 of the lower cheek so as to be in contact with the external face 352 of the intermediate side cheek 35 and the lower cheek 32 and between the fillet 38 of the lower cheek and the second edge 354 of the intermediate side cheek 35 forming a complementary rounding of the fillet 38.
- the third covering 53 is, unlike the first covering 51 and the second covering 52, formed between the main side cheek 33 and the first longitudinal end 36 of the lower cheek so that the brazing formed by this third covering 53 is an edge-to-edge brazing between the main side cheek 33 and the lower cheek 32.
- the housing 3 comprises, at least at each junction zone 5, a first brazing between the intermediate side cheek 35 and the upper cheek 31 and/or the lower cheek 32, a second brazing between the intermediate side cheek 35 and the main side cheek 33 and a third brazing between the main side cheek 33 and the upper cheek 31 and/or the lower cheek 32.
- each junction zone 5 The joining of the different cheeks at the level of each junction zone 5 allows the housing 3 to be hermetically sealed closed at the level of each of the distinct faces of the faces through which the gas flow enters the exchange beam 2.
- the invention as it has just been described achieves the goals that it had set for itself, and allows us to offer a heat exchanger within which the side cheeks of the housing are hermetically reinforced. Variants not described here could be implemented without departing from the context of the invention, since in accordance with the invention, they comprise a heat exchanger in which an intermediate side cheek is interposed between the exchange bundle and a main lateral cheek.
