Definitions

  • the invention relates to a plate heat exchanger, capable of performing a heat exchange between two fluids and usable in particular for cooling the lubricating oil, that is to say the engine oil and / or the oil of the gearbox of a motor vehicle.
  • the plates usually have the general shape of a disc which has a circular peripheral lip and a circular inner lip which is intended to surround a central tube around which the pairs of plates are stacked.
  • the homologous lips of two facing plates, forming part of the same pair are joined together, by example by brazing, these two plates define an annular blade for the circulation of the first fluid, for example oil.
  • the two communication openings made through each plate serve, one at the inlet and the other at the outlet, for the second fluid, for example oil.
  • Each of these two openings is bordered by a lip capable of being joined in a sealed manner to a homologous lip of an adjacent plate.
  • a heat exchanger of this type is used in particular for cooling the lubricating oil from an engine block.
  • the latter is used, on the one hand, for fixing the heat exchanger on the engine block and, on the other hand, for fixing an oil filter on the heat exchanger.
  • This hollow central tube is then used to return the oil to the engine block, either directly in the tube, or via the threaded axis which is then made hollow.
  • these known heat exchangers usually comprise a bypass fitted with a valve which is normally open when the oil is cold and viscous, and closed when the oil is hot and fluid.
  • valve When the oil is cold and viscous, the valve is in the open position and the oil then passes directly through the exchanger from the inlet to the bypass, passing through the plate inlet openings to reach the filter and return to the engine through the tube or central axis.
  • the valve When the oil is hot and fluid, the valve is in the closed position, and the oil is distributed in each blade through the plate inlet openings and it leaves each blade through the plate outlet openings to reach a passage communicating with the filter.
  • the oil returns to the engine via the duct or the central axis, the oil then being cooled by exchange thermal with the first fluid, that is to say the coolant which passes through the housing.
  • the flow-disturbing elements are disc-shaped parts which are each housed in the space delimited between the two plates of the same pair. These plates are provided with reliefs in the form of fins or the like which disturb the flow of oil in the plates to facilitate heat exchange.
  • the circulation of oil within each blade of a pair of plates is slowed down by the reliefs of the disturbing element.
  • the oil hardly succeeds in sweeping the reliefs, in the form of fins, of the disturbing elements, especially at the periphery of the plates.
  • the housing is usually provided with an inlet pipe and an outlet pipe for the second fluid, which are located close to each other on the side wall of the housing.
  • the two pipes then open respectively into two adjacent compartments formed between the side wall of the housing and the stack of plates.
  • the compartment connected to the inlet pipe allows the first fluid to be admitted simultaneously into the spaces defined between the pairs of plates, while the compartment connected to the outlet pipe allows the second fluid to exit simultaneously from the aforementioned spaces.
  • the object of the invention is in particular to overcome the aforementioned drawbacks.
  • each plate has substantially the shape of a square, in which the two communication openings of each plate are arranged on either side of the stacking direction and located in an alignment direction parallel to two sides of the square, and in which each disturbing element comprises lines of corrugation in the form of fins which extend in a direction parallel to the direction of alignment of plate openings.
  • the first fluid for example oil
  • the first fluid which penetrates into the circulation plate defined by a pair of plates, can completely sweep the disturbing element and all the space defined between the two plates.
  • the first fluid can reach the periphery of the disruptor and the circulation blade.
  • the corrugations are formed of planar segments connected in pairs by an obtuse angle.
  • the undulations of two adjacent undulation lines are offset.
  • Each disturbing element is advantageously produced in the form of a stamped part of generally square shape comprising a central cut of elongated shape.
  • the communication openings of each plate have a square or rectangular shape with sides generally parallel to the sides of the plate.
  • the first fluid entering inside a pair of plates escapes in directions which are parallel or perpendicular to the corrugation lines, which facilitates the circulation of the fluid.
  • one of the communication openings which serves for the entry of the first fluid, has a square shape
  • the other communication opening which serves for the exit of the first fluid fluid
  • the housing has a cross section of substantially square shape and is limited by four flat side faces of substantially rectangular shape.
  • One of the four lateral faces of the housing serves as a connection face and is provided with an inlet pipe and an outlet pipe for the second fluid, these two pipes respectively opening into two symmetrical parts of the connection face. extending on either side of a center line which is parallel to the stacking direction.
  • This midline serves as a delimitation between two compartments into which the two aforementioned tubes open respectively.
  • each of the plates has, on the side of the connection face, a non-rectilinear front side formed by two parts interconnected by an obtuse angle, the apex of which abuts against the face of connection to the level of the midline of the latter.
  • This characteristic makes it possible to delimit the two aforementioned compartments inside the housing.
  • each plate of the stack comprises a boss which extends outwards and in the direction of alignment of the communication openings and which ends at the top of the obtuse angle on the front side.
  • each plate of the stack comprises a boss which extends outwards and in the direction of alignment of the communication openings.
  • the front side of the plate can be straight and then come into abutment against a bulge on the front face of the housing.
  • This boss is advantageously connected to a lip which surrounds one of the two communication openings and which is itself connected to a lip which surrounds a central hole serving for the passage of a central tube directed in the stacking direction.
  • the plate further includes a lip surrounding the other communication opening.
  • the leaf heat exchanger shown in Figures 1 and 2 comprises a housing 10 delimited by a cylindrical envelope of substantially square section, the generators of which are parallel to an axis XX.
  • the casing envelope is limited by four flat side faces 12, 14, 16 and 18 of substantially rectangular shape, connected in pairs by four rounded faces 20 (FIG. 2).
  • the face 12 serves as a connection face and is provided with an inlet pipe 22 and an outlet pipe 24 for a fluid, in the example the coolant of a thermal engine of a motor vehicle.
  • the two pipes 22 and 24 open respectively into two symmetrical parts of the connection face 12, which extend on either side of a center line L which is parallel to the direction XX ( Figure 2).
  • the heat exchanger further comprises a stack of plates 26 arranged in pairs 26-1 and 26-2 and alternately inside the housing 10, in the direction XX which also constitutes the stacking direction.
  • the two plates 26-1 and 26-2 also called “half-plates", of the same pair, are substantially identical ( Figure 1).
  • the plate 26-1 ( Figure 5), located in the lower part, has substantially the shape of a square bounded by a non-rectilinear front side 28 and three other sides 30, 32, 34, all three rectilinear.
  • the sides 28, 30, 32 and 34 are connected two by two by four rounded edges 36.
  • the front side 28 is formed by two rectilinear parts 28-1 and 28-2 connected together by an obtuse angle, the apex 38 of which abuts against the connection face 12 at the level of the midline L of the latter (FIG. 2 ). It will be understood that the plates 26 have dimensions slightly smaller than the internal dimensions of the housing in order to be able to register therein.
  • Two compartments 40 and 42 are thus defined in the housing (FIG. 2) which are in communication respectively with the inlet pipe 22 and with the outlet pipe 24.
  • Each plate 26-1 is provided with an external collar 44-1 which receives a homologous external collar 44-2 with a plate 26-2 and an internal collar 46-1 of circular shape which receives a homologous internal collar 46 -2 of plate 26-2 ( Figure 1).
  • a circulation plate 48 for a first fluid in the example of the lubricating oil, intended to be cooled by the aforementioned second fluid.
  • the stack of plates 26 is inserted into the housing 10 around a central tube 50 against which the collars 46-2 are supported.
  • each blade 26 has two diametrically communicating openings opposite, namely an inlet opening 52 and an outlet opening 54. These two openings are arranged on either side of the stacking direction XX while being located in an alignment direction A parallel to the two sides 30 and 34 of plate 26 ( Figure 5).
  • Direction A is also parallel to sides 14 and 18 of the housing ( Figure 2).
  • Each of the plates 26 further comprises a circular central hole 56 for the passage of the central tube 50.
  • Each of the plates 26 comprises a peripheral lip 58 of circular shape which surrounds the hole 56, is connected to a peripheral lip 60 of generally rectangular shape which surrounds the orifice 52 and to which is connected a boss 62 which extends in the direction of alignment A of the openings 52 and 54 and which terminates at the top of the obtuse angle 38 on the front side 28 (FIG. 5).
  • each of the plates 26 comprises a lip 64 of generally rectangular shape which surrounds the communication opening 54 (FIG. 5). The different aforementioned lips are formed in relief and towards the outside of each of the plates 26-1 and of each of the plates 26-2.
  • the aforementioned lips seal the communications between the pairs of plates, in particular at the level of the communication openings 52 and 54. Furthermore, the bosses 62 come into contact with each other and make it possible to delimit in the housing, two regions communicating respectively with the compartments 40 and 42. Thus, the cooling fluid entering through the tube 22 sweeps all of the plates and exits through the tube 24.
  • the two plates 26-1 and 26-2 of the same pair are joined together by brazing at their respective collars and the plates are joined together in pairs between them by brazing at their respective lips 58, 60 and 64 , and their respective bosses 62.
  • the communication opening 52 for the entry of the oil has a substantially square shape with sides parallel to the sides of the square of the plate.
  • the communication opening 54 serving for the outlet of the fluid has a generally rectangular shape, the largest dimension of the rectangle extending transversely to the direction of alignment A of the two communication openings.
  • the square or rectangular shapes of the openings 52 and 54 facilitate the diffusion of the oil in each of the blades 48 by favoring two perpendicular directions.
  • the heat exchanger further comprises a multiplicity of disturbing elements 66 housed respectively in the blades 48 for circulation of the oil.
  • the disturbing element 66 (FIG. 3) is produced in the form of a stamped part of generally square shape homologous to that of the plates 26.
  • the plate 66 has a front side 68 formed by two rectilinear parts 68-1 and 68-2 connected together by an obtuse angle 70, and three other rectilinear sides 72, 74 and 76. These four sides are joined together in pairs by rounded 78.
  • the disturbing element 66 comprises a central cutout 80 of elongated shape, the outline of which includes the communication openings 52 and 54 and the central opening 56 of the plates.
  • the disturbing element 66 is provided with a multiplicity of corrugation lines 82 forming fins and which extend parallel to the alignment direction A of the plate openings (FIG. 3). These wavy lines are formed in relief by stamping.
  • the undulations of the lines 82 have a shape resembling a sinusoid, but they are formed of plane segments 84 situated in the same plane, planar segments 86 situated in a parallel plane and intermediate segments 88 connecting two by two the segments 84 and 86.
  • the segments 88 form an obtuse angle equal with the segments 84 on the one hand and the segments 86 on the other.
  • the oil which enters a blade 48 through an inlet opening 52 can reach the periphery of the blade by sweeping all the corrugation lines 82, and without being braked by them, which reduces the pressure drop and also allows good heat exchange with the coolant.
  • the oil thus cooled can then easily flow through the outlet openings 54.
  • each of the plates 26 also comprises a multiplicity of studs 90 projecting inwardly and acting as spacers to keep the disturbing element 66 away from the two plates 26- 1 and 26-2 surrounding it.
  • the heat exchanger ( Figure 1) further comprises an annular bottom 92 which has an opening 94 located in alignment with the openings 52 and thus constituting the oil inlet of the exchanger.
  • the bottom 92 is held by a seal holder cup 94 disposed between the casing of the housing and the central tube 50.
  • the heat exchanger comprises a seal carrier cup 96 connected to the casing of the housing and to the central tube 50.
  • This cup comprises a bypass 98 located in the axial alignment of the openings 52 and controlled by a valve. 100, as well as an opening 102 arranged in alignment with the openings 54.
  • the heat exchanger is intended to be fixed to an engine block 104 and to receive an oil filter 106, the fixing of the exchanger on the engine block and the fixing of the oil filter on the exchanger is effected for example by means of a hollow threaded pin.
  • the exchanger operates as follows. When the oil is cold and viscous, it enters the exchanger through the opening 94 and, under the effect of the high viscosity of the cold oil, this results in an increase in the pressure which causes the opening of the valve 66. The oil passes directly through the exchanger from the inlet 94 to the bypass 98 passing through the openings 52. The oil then passes through the filter and returns to the engine block via the central tube 50.
  • valve 100 When the oil is hot and fluid, the valve 100 is closed. The oil is then distributed in each blade 48 through the openings 52 and it emerges from each blade through the openings 54 to reach the opening 102. It then passes through the filter 106 and returns to the engine block through the central tube 50 .
  • the heat exchanger of the invention thus allows an optimal heat exchange between the oil to be cooled and the coolant, and this with a minimum pressure drop.
  • the invention is not limited to a heat exchanger usable as an oil radiator.
