Definitions
- the field of the present invention is that of heat exchangers, in particular heat exchangers for automobiles. More particularly, the present invention relates to a heat exchanger plate as defined in the preamble of claim 1, and as illustrated in figure 4 of the document FROM 10 2016 006127 .
- Motor vehicles are commonly equipped with heat exchangers. These allow calories to be transferred from one fluid to another fluid and are used, for example, to cool internal combustion engines.
- exchangers are plate exchangers and they are used to cool liquids such as oil. These exchangers comprise a stack of plates between which a plurality of channels are formed.
- the efficiency of these heat exchangers depends on the intensity of the heat exchange between the fluids, but also on the distribution of the fluids in the channels.
- the plate heat exchanger also includes a collector that distributes the fluid in each of the channels with which it is connected. This collector is formed by openings made in each of the plates.
- this collector has a circular section and the openings that constitute it are also circular in shape.
- this opening shape is not optimal. Indeed, a lack of homogeneity in the fluid supply of the channel has been noted.
- the circular shape of the opening generates areas of the channel where the fluid circulates with difficulty. Such defects generate areas where heat exchange is reduced.
- the aim of the present invention is therefore to resolve the drawback described above by improving the distribution of the fluid over a large part of the width of the channel.
- the invention therefore relates to a heat exchanger circulation plate according to claim 1.
- the presence of an at least partly rectilinear edge to define the opening optimizes the circulation of the fluid, by forcing it to spread over a greater width of the circulation plate. This homogenizes the circulation of the fluid over the width of the channel, thereby reducing temperature differences on the surface of the plate.
- This opening shape also optimizes fluid circulation by limiting obstruction of the at least one circulation channel and preventing the formation of dead zones on the circulation plate.
- the two fluids circulating on either side of the plate are a refrigerant fluid and a heat transfer fluid.
- the circulation plate is thus configured to delimit a first channel traversed by the refrigerant fluid and a second channel traversed by the heat transfer fluid.
- the straight part of the edge is part of the bottom.
- the at least partly rectilinear edge forms a first edge, the opening being delimited by a second edge which is part of the raised edge.
- the opening is delimited by a first edge which is at least partly rectilinear and formed on the bottom, and by the second edge which is part of the raised edge.
- the position of the second edge on the raised edge makes it possible to limit the dead zones which are usually found between the opening and the raised edge.
- the dead zones are characterized by a low heat exchange, they therefore reduce the performance of the plate heat exchanger.
- the at least partly rectilinear edge forms a first edge, the opening being delimited by a second edge which is part of the bottom.
- the second edge can follow a homothetic profile with a curved part of the raised edge.
- the fluid moves along the circulation plate in a flow direction, the straight part of the edge extending along a straight line transverse to the flow direction.
- the bottom comprises a rib arranged so that the channel has a U-shaped profile.
- At least the opening is at least partly surrounded by a collar which emerges from the bottom and of which at least one plate extends in a plane substantially parallel, advantageously parallel, to a plane in which the bottom extends.
- the plate is configured to come into abutment against a bottom of an adjacent plate.
- the collar at least partially surrounds the opening which comprises the at least partly rectilinear edge.
- the at least partly rectilinear edge is formed on the plateau of the collar.
- the collar comprises a flank which at least partly surrounds the opening and which is interposed between the bottom and the plate.
- the circulation plate is rectangular in shape and comprises a first longitudinal end and a second longitudinal end, a first opening without a collar being provided at the first longitudinal end of the circulation plate, while a second opening having a collar is provided at the second longitudinal end of the circulation plate.
- the bottom includes at least one fluid flow disruptor.
- the bottom may include a plurality of disruptors that emerge from the bottom and extend into the channel.
- the flow disruptors are used to create a turbulent flow that runs along the flow plate. They disrupt the boundary layer of the refrigerant and/or heat transfer fluid that flows in the channel(s).
- At least one opening has an oblong shape.
- At least one opening may have a triangular or rectangular shape.
- the shape of the opening referred to here is observed according to a viewing angle of direction perpendicular to a plane in which the bottom extends.
- opening shapes allow the fluids to be distributed over a greater part of the width of the circulation plate and thus maximize the exchange surfaces. They also make it possible to reduce the space between the two openings, usually not very thermally active.
- the heat exchanger comprises at least one circulation plate according to any one of the preceding characteristics.
- the plate is a closing plate of the heat exchanger or a circulation plate of this heat exchanger.
- the heat exchanger comprises two circulation plates which are nested one inside the other and which delimit between them the channel capable of being used by a refrigerant fluid or a heat transfer liquid.
- three circulation plates are nested within each other and delimit two by two a first channel and a second channel, the first channel being configured to be used by a refrigerant fluid while the second channel is configured to be used by a heat transfer liquid.
- a longitudinal direction A corresponds to the main axis of the plates in which they extend predominantly, while the lateral orientations correspond to concurrent straight lines, i.e. which intersect the longitudinal direction, in particular perpendicular to the longitudinal axis of the plates.
- the longitudinal direction A is parallel to a longitudinal axis 1 of a trihedron 1, v, t, while the lateral direction B is parallel to a transverse axis t of the trihedron, the stacking direction being parallel to a vertical axis v of the trihedron.
- FIG. 1 shows in perspective a heat exchanger 20 not in accordance with the invention.
- the heat exchanger 20 implements an exchange of calories between a first fluid and a second fluid.
- the first fluid is for example a refrigerant fluid and the second fluid is for example a heat transfer liquid.
- the heat exchanger according to the invention is configured so that the refrigerant fluid and the heat transfer fluid exchange calories without coming into contact. This characteristic will be detailed later in the rest of the detailed description.
- the heat exchanger 20 comprises a heating body 15 where the heat exchange between the refrigerant and the heat transfer fluid takes place.
- the heating body 15 is formed by a superposition of plates, in a stacking direction d.
- the plates according to the invention are the circulation plates 1 and at least one closing plate 2a, intended to seal the upper part of the heating body 15 in the stacking direction d.
- This closing plate 2a is positioned on top of the set of circulation plates 1 of the heating body 15, in the stacking direction d.
- the closing plate 2a and the circulation plate 1 are grouped together in this document under the term plate, and the characteristic(s) described in connection with this term apply identically to the closing plate 2a and the circulation plate 1.
- the heat exchanger 20 also comprises a closing cheek 2b, intended to seal the lower part of the heating body 15 in the stacking direction d.
- This closing cheek 2b is positioned below all of the circulation plates 1 of the heating body 15, that is to say opposite the closing plate in the stacking direction d relative to the circulation plates 1.
- the circulation plates 1, the closing plate 2a and the closing cheek 2b have a bathtub-shaped configuration.
- One edge of the plate according to the invention i.e. at least the circulation plate 1 or the closing plate 2a or the closing cheek 2b, is a raised edge 5 which surrounds a bottom 3, thus forming a bottom of the bathtub.
- the bottom 3 of the plate has a rectangular shape with rounded edges.
- the raised edge 5 of the plate according to the invention which surrounds the bottom 3 extends continuously all around the bottom 3 and has longitudinal and lateral rectilinear parts, joined by curved parts provided at each corner of the plate according to the invention.
- the closing plate 2a and at least one circulation plate 1 comprise at least one opening 7.
- the closing plate 2a and the circulation plate comprise four openings referenced 7a, 7b, 7c and 7d.
- the first opening 7a and the fourth opening 7d are positioned at a first longitudinal end 110 of the plate.
- the second opening 7b and the third opening 7c are positioned at a second longitudinal end 120 of the plate according to the invention.
- the first opening 7a, the second opening 7b, the third opening 7c and the fourth opening 7d present on this figure 1 each an oblong shape.
- Oblong is understood to mean a shape that is longer than it is wide. This oblong shape is visible in a plane AB of the plate concerned.
- the first opening 7a has a side which extends in the longitudinal direction A of the circulation plate 1 or closing plate 2a and which runs along a part of the raised edge 5 formed at the first longitudinal end 110 of the plate. This characteristic also applies to the second opening 7b, third opening 7c and fourth opening 7d.
- the closing cheek 2b positioned under the stack of circulation plates 1 in the direction d does not have any openings, so that the heat transfer fluid and the refrigerant fluid do not escape from the heating body 15.
- the heat exchanger 20 extends in the longitudinal direction A and also comprises a first longitudinal end 110 and a second longitudinal end 120, the first longitudinal end 110 being opposite the second longitudinal end 120.
- the heat exchanger 20 has four collectors 8, a first collector 8a, a second collector 8b, a third collector 8c and a fourth collector 8d.
- the first collector 8a and the fourth collector 8d are each positioned in a corner of the first longitudinal end 110 of the heat exchanger 20.
- the second collector 8b and the third collector 8c are each positioned in a corner of the second longitudinal end 1 of the heat exchanger 20.
- the first collector 8a, the second collector 8b, the third collector 8c and the fourth collector 8d are volumes extending in the stacking direction d of the heating body 15. These collectors have the function of distributing or collecting the heat transfer liquid or the refrigerant fluid in the first channels 30a and in the second channels 30b (visible in the figure 2 ).
- a collector volume 8 is delimited on one side by the opening 7 of the closing plate 2a, by the closing cheek 2b and by each of the openings 7 of the circulation plates 1, as will be detailed later.
- the heat transfer fluid and the refrigerant circulate separately in the heat exchanger 20.
- the first collector 8a and the fourth collector 8d are the collectors 8 reserved for the distribution or collection of the heat transfer fluid in the heating body 15.
- the second collector 8b and the third collector 8c are the collectors intended to distribute or collect the refrigerant in the heating body 15.
- the first collector 8a is the inlet of the heat transfer fluid into the heating body 15 and the fourth collector 8d is the outlet of the heat transfer fluid from the heating body 15. Equivalently, the second collector 8b is the inlet of the refrigerant fluid into the heating body 15 and the third collector 8c is the outlet of the refrigerant fluid from the heating body 15.
- FIG 2 shows a side sectional view of a stack of circulation plates 1 according to a plane B, d of the figure 1 .
- the superposition of the circulation plates 1 delimits channels 30 which are distinct from each other.
- a first channel 30a is arranged to be traversed by the refrigerant fluid and a second channel 30b is arranged to be traversed by the heat transfer liquid.
- the heating body is organized so as to comprise an alternation of first channel 30a and second channel 30b along the stacking direction. The circulation of the refrigerant fluid and the heat transfer liquid in the heating body is therefore carried out alternately between the first channel 30a and the second channel 30b.
- FIG. 2 illustrates the presence of disruptors 13 of the fluid flow which are arranged on the bottom 3 of the circulation plate 1.
- the disruptors 13 extend above a general extension plane of the bottom 3 of the circulation plate 1, emerging above the bottom 3 in the channel.
- the disruptors 13 have the function of disturbing the boundary layer of the heat transfer fluid and/or the refrigerant fluid in the first channel 30a, respectively in the second channel 30b. Thus, the disruptors 13 maximize the heat exchanges between the refrigerant fluid and the heat transfer fluid.
- Traffic plate 1 of the figure 2 comprises the raised edge 5, the latter being divided into a first longitudinal raised edge 5a, a second longitudinal raised edge 5b, a first lateral raised edge 5c and a second lateral raised edge, not visible in this figure. These longitudinal and lateral raised edges are joined by curved raised edges 5e, 5f, 5g and 5b, as is apparent in the figures 1 And 3 has 5 .
- the raised edge 5 comprises an upper face 38 and a lower face 39. A portion of the lower face 39 of the raised edge 5 of a first circulation plate 1 comes into contact with a portion of the upper face 38 of the raised edge 5 of a second circulation plate 1. This contact between walls, made over the entire periphery of the raised edge 5, generates a seal between two circulation plates 1, so as to form the first channel 30a or the second channel 30b. This characteristic applies to all of the raised edges of the circulation plates 1, the closing plate 2a and the closing cheek 2b of the heat exchanger 20 of the invention.
- the raised edge 5 of the circulation plate 1 ends with a peripheral flank 50.
- This peripheral flank 50 extends in a plane parallel to the plane of the bottom 3 of the circulation plate 1 and goes all the way around the circulation plate 1. It will be noted that the peripheral flank 50 of a first circulation plate 1 is distant from the peripheral flank 50 of the second circulation plate 1 which is nested in the first circulation plate 1. This characteristic applies to all of the raised edges of the circulation plates 1 of the heat exchanger 20.
- the circulation plate 1 has a bottom 3 having an upper face 100 and a lower face 101.
- the stacking of the circulation plates 1 in the stacking direction d is characterized by the fact that the lower face 101 of the bottom 3 of a first circulation plate 1 is opposite and at a non-zero distance from the upper face 100 of the bottom 3 of a second circulation plate 1, immediately adjacent to the first circulation plate 1. This is how the first channel 30a and the second channel 30b are created.
- There figure 3 illustrates a traffic plate 1 according to a first embodiment not in accordance with the invention.
- the circulation plate 1 has the shape of a bathtub, that is to say that it comprises the bottom 3, surrounded continuously on its periphery by the first longitudinal raised edge 5a, the second longitudinal raised edge 5b, the first lateral raised edge 5c, the second lateral raised edge 5d, a first curved raised edge 5e, a second curved raised edge 5f, a third curved raised edge 5g and a fourth curved raised edge 5h.
- the curved raised edges are arranged at the corners of the plate according to the invention, and join a longitudinal raised edge to a lateral raised edge.
- the circulation plate 1 extends in the longitudinal direction A between the first longitudinal end 110 and a second longitudinal end 120, the first longitudinal end 110 being opposite the second longitudinal end 120 relative to the bottom 3.
- Each traffic plate 1 comprises at least one opening 7.
- the circulation plate 1 comprises four openings 7, a first opening 7a, a second opening 7b, a third opening 7c and a fourth opening 7d.
- the first opening 7a and the fourth opening 7d are positioned at the first longitudinal end 110 of the circulation plate 1.
- the second opening 7b and the third opening 7c are positioned at the second longitudinal end 120 of the circulation plate 1.
- the first opening 7a, the second opening 7b, the third opening 7c and the fourth opening 7d of the circulation plate 1 have an oblong shape, seen in the plane AB.
- the opening 7 is therefore longer than it is wide, and this elongation is carried out along the transverse direction B.
- the first opening 7a, the second opening 7b, the third opening 7c or the fourth opening 7d of the circulation plate 1 have the first edge 9a straight and parallel to the lateral raised edge 5c, 5d.
- the opening concerned is also delimited by the second edge 9b which runs along the lateral raised edge 5c, 5d and the curved raised edge 5e, 5f, 5g, 5h.
- the first straight edge 9a and the second edge 9b form a slice of the bottom 3 of the circulation plate 1.
- the second edge 9b which delimits the opening 7 illustrated in this figure 3 has a first portion which is parallel to the lateral raised edge 5c, 5d and a second portion which follows the curvature of the curved raised edge 5e, 5f, 5g, 5h.
- the collar 10 is a shoulder which emerges from the bottom 3 of the circulation plate 1.
- the collar 10 is composed of a plate 10a and a second collar part 10b.
- the plate 10a extends above the plane AB of the bottom 3 of the circulation plate 1, and parallel to it, while the second collar part 10b joins the bottom 3 to the plate 10a.
- a circulation plate 1 will comprise at least one collar positioned on at least one opening 7 of a first longitudinal end 110 and the adjacent circulation plate 1 following the stack will comprise at least one collar on at least one opening 7 of a second longitudinal end 120.
- the heating body comprises a plurality of circulation plates 1 where at least one collar is alternately formed at one longitudinal end of the heating body or at the other longitudinal end of the heating body.
- each pair of openings 7 positioned at the first longitudinal end 110 and at the second longitudinal end 120 of the circulation plate 1 corresponds separately to an inlet and an outlet of the refrigerant fluid or the heat transfer liquid.
- the first opening 7a corresponds to an inlet of the heat transfer liquid
- the fourth opening 7d corresponds to the outlet of the heat transfer liquid.
- the second opening 7b corresponds to the inlet of the refrigerant fluid
- the third opening 7c corresponds to the outlet of the refrigerant fluid.
- the circulation plate 1 further comprises a rib 11 which emerges from the bottom 3 of the circulation plate 1 and which extends in the longitudinal direction A.
- This rib 11 begins from the first lateral raised edge 5c, between the first opening 7a and the fourth opening 7d, and extends in the direction of the second longitudinal end 120 of the circulation plate 1.
- the rib 11 ends at a non-zero distance from the second lateral raised edge 5d and thus divides the volume delimited by two circulation plates 1 to form the U-shaped channel.
- the bottom 3 of the circulation plate 1 is provided with fluid flow disruptors 13. These are arranged in rows parallel to each other and aligned parallel to the transverse direction B. At least one of these rows of disruptors 13 is parallel to the straight edge 9a. These rows are offset in the transverse direction B, so that the disruptors 13 are arranged in a staggered manner from one row relative to the other, thus forming spans of disruptors 13 parallel to the longitudinal direction A.
- FIG 4 illustrates an embodiment of the circulation plate 1 according to the invention.
- the figure 3 illustrates an embodiment of the circulation plate 1 according to the invention.
- FIG 4 presents the first longitudinal end 110 of the circulation plate 1.
- the first opening 7a and the fourth opening 7d are delimited by a first straight edge 9a and by a second curved edge 9b which follows the curvature of the curved raised edge 5e, 5h of the circulation plate 1.
- the opening concerned is thus entirely delimited by the first straight edge 9a and by the second curved edge 9b.
- the first straight edge 9a extends along a direction which is transverse to the longitudinal direction A and to the transverse direction B.
- the direction in which the straight portion of the first edge 9 extends forms an angle with the longitudinal direction A of the circulation plate 1 of between 30 and 60°, advantageously 45°. It will be noted that the direction in which the straight portion of the first edge 9 extends intersects the lateral raised edge 5c, between the rib 11 and the curved raised edge 5e, and also intersects the longitudinal raised edge 5a, between two curved raised edges located on either side of the longitudinal raised edge 5a.
- a collar may be formed around these triangular-shaped openings 7.
- the opening 7 delimited by this first straight edge 9a and by this second curved edge 9b is formed in the bottom 3.
- the first straight edge 9a and the second curved edge 9b are therefore sections of the bottom 3 of the circulation plate 1.
- the opening(s) 7 illustrated on this figure 4 have a triangular shape, seen in a plane AB, with rounded corners.
- Traffic plate 1 according to the variant illustrated in figure 4 presents 13 disruptors on its background 3. Unlike the figure 3 , the triangular nature of the openings 7 allows an arrangement of disruptors 13 in the vicinity of the first longitudinal end 110 of the circulation plate 1.
- the circulation plate 1 comprises disruptors 13 which are arranged between the rib 11 and the opening 7.
- a line of disruptors 13 is parallel to the straight part of the first edge 9a.
- the first opening 7a and the fourth opening 7d have a first straight edge 9a formed by the bottom 3 of the circulation plate 1.
- the first straight edge 9a is a slice of the bottom 3 of the circulation plate 1 and the straight part is parallel to the first lateral raised edge 5c.
- the second opening 7b and the third opening 7c also have a first straight edge 9a formed by the collar 10 which emerges from the bottom 3 of the circulation plate 1, as detailed in figure 3 .
- the first straight edge 9a which delimits this second opening 7b or this third opening 7c is a slice of this collar 10 and the straight part is parallel to the second lateral raised edge 5d.
- the opening(s) 7 illustrated on this figure 5 also have a second edge 9b, a first portion of which is parallel to the lateral raised edge 5c, 5d and a second portion follows the curvature of the curved raised edge 5e, 5f, 5g, 5h.
- the second edge 9b in particular its first portion and its second portion, is part of the raised edge 5. More precisely, the first portion of the second edge 9b is a slice of the lateral raised edge 5c and the second portion of the second edge 9b is a slice of the curved raised edge 5e which adjoins the lateral raised edge 5c.
- the opening(s) 7 of the third mode of realization extend in the plane of the bottom 3 and also in a plane which follows the profile of the raised edge 5.
- the opening 7 concerned has an L-shaped section, seen in a plane parallel to the longitudinal direction A and perpendicular to the bottom 3.
- opening 7 applies of course to the openings 7c, 7d which are surrounded by the collar 10, such as those provided at the second longitudinal end 120.
- the first edge 9a and its straight part belong to the collar 10, while the second edge 9b is part of the raised edge 5.
- the invention thus achieves the goal it set for itself by improving the distribution of the fluid across the width of the channel, thereby improving the temperature homogeneity across this width.
- the invention cannot, however, be limited to the means and configurations exclusively described and illustrated, and also applies to all equivalent means or configurations and to any combination of such means or configurations.
- the invention has been described here in its application to a refrigerant fluid/heat transfer liquid heat exchanger, it goes without saying that it applies to any shape and/or dimension of the plate or to any type of fluid circulating along the plate according to the invention.
