Definitions
- Heat exchanger plate especially for an air conditioning condenser
- the invention relates to heat exchangers, in particular for motor vehicles.
- It relates more particularly to a heat exchanger plate for the production of a heat exchanger comprising a stack of such plates to form between them first channels for the circulation of a first fluid which alternate with second channels for the circulation of a second fluid.
- plate heat exchangers have different applications, particularly in the field of motor vehicles where they are used, for example, as oil coolers or as air conditioning condensers.
- a cooling fluid is cooled by a cooling fluid which is generally the vehicle engine cooling fluid, that is to say water with antifreeze.
- a cooling fluid which is generally the vehicle engine cooling fluid, that is to say water with antifreeze.
- Heat exchanger plates are already known which comprise a generally rectangular bottom provided with four fluid passage openings, respectively arranged in four corner regions, and provided with chevron corrugations extending from one side to the other. another of a median longitudinal axis of the plate.
- the corrugations of the plate are intended to intersect with the corrugations of an identical adjacent plate in a superimposed relationship where the two plates are rotated 180 ° mutually, forming point contact areas for their mutual brazing.
- each plate is deformed locally around the fluid passage openings to allow opening or closing the passage section to the fluid concerned, that is to say either the first fluid or the second fluid. This then makes it possible to perform an alternating circulation of the two fluids.
- Plate heat exchangers have the main disadvantage of having a low mechanical strength because they offer a large surface subjected to the pressure of the fluid, and this without mechanical reinforcement. Indeed, these plates are soldered to each other at their peripheral edge, around the passage openings and at the point contact areas at the intersection of herringbone corrugations.
- the current plates do not provide sufficient mechanical reinforcement in the corner regions where are located respectively the four passage openings.
- the main purpose of the invention is to overcome this disadvantage. It proposes for this purpose that the bottom of the plate has, in the peripheral regions, in particular corner for the rectangular plates, and / or near the passage openings, additional reliefs suitable for defining additional point contact zones for the brazing, which improves the pressure resistance of the heat exchanger.
- a first corrugation close to two openings passing through a first end of the plate and a second corrugation close to two openings passing through a second end of the plate each have a continuous portion and a discontinuous portion in a branch of the chevron between the median longitudinal axis and a large side of the plate, the discontinuous portion forming the additional reliefs.
- each branch of the chevron comprises a continuous portion and a discontinuous portion forming additional reliefs.
- this discontinuous portion may comprise an aligned series of recesses and bumps arranged alternately.
- the additional reliefs may further comprise end reliefs respectively located at both ends of the plate between two fluid passage openings and each extending symmetrically on either side of the median longitudinal axis.
- the invention in another aspect, relates to a heat exchanger comprising a multiplicity of plates as defined above, in which the plates are mutually identical and mutually stacked by being turned in pairs by 180 °, forming contact zones. punctures for brazing.
- This heat exchanger can in particular be made in the form of a condenser for cooling a cooling fluid with a cooling fluid.
- FIG. 3 is a top view of the plate of Figure 1 in a rotated position of 180 °;
- - Figure 4 is a partial view of an assembly of two blades in an area defined by the section along the line IV-IV of Figure 3, on an enlarged scale;
- FIGS. 5 and 6 are two enlarged details of FIG.
- FIG. 2 illustrating the brazing zones at the end regions of the plate
- Figure 7 is a schematic top view of a heat exchanger plate according to the prior art on which are shown a portion of the corrugations of a superimposed plate
- Figure 8 is a schematic top view of a heat exchanger plate according to the invention which is also shown a portion of the corrugations of an identical plate superimposed
- Figure 9 is a top view of an embodiment of a heat exchanger plate according to Figure 8
- FIG. 10 illustrates the brazing zones of the heat exchanger plate of FIG. 9;
- FIG. 11 is a partial sectional view showing the soldering zones provided by a portion of the additional reliefs
- FIG. 12 represents an enlarged detail of FIG. 10;
- FIG. 13 illustrates the brazing points provided by the additional reliefs at the ends of the plate corresponding to FIG. 12;
- Fig. 14 shows another enlarged detail of Fig. 10; and
- FIG. 15 illustrates the brazing points provided by the additional reliefs at the ends of the plate corresponding to FIG. 14.
- FIG. 1 shows a plate 10 for a heat exchanger according to FIG. prior art.
- the plate 10 comprises a bottom 12 of generally rectangular shape bounded by two long sides 14 and two small sides 16 joined together by rounded 18.
- the bottom 12 is generally flat and surrounded by a raised peripheral edge allowing a mutual interlocking and an assembly sealing plate, as taught, for example, by the publication FR 2 795 165.
- the bottom 12 is provided with four fluid passage openings 22 arranged respectively in four corner regions, that is to say near the rounded 18.
- the bottom 12 is provided with corrugations 22 in the form of chevrons which extend on either side of a median longitudinal axis XX. These corrugations are formed by an alternating succession of ribs and longitudinal grooves forming V-shaped reliefs each of which has its apex on the axis XX and its branches arranged symmetrically on either side of the latter.
- the openings 22 are each surrounded by annular borders 24 intended to provide brazing areas around the openings.
- Two of the annular borders 24 are in the plane of the bottom 12 and the other two are in an offset plane as shown by hatched areas. In the example, the latter are arranged diagonally, but they could be arranged differently, for example along a long side.
- Such plates are advantageously obtained by cutting and stamping a metal foil, typically based on aluminum, coated with a solder plating.
- a plate heat exchanger can be formed by a stack of plates 10, the plates being mutually rotated by 180 °, which makes it possible to use the same type of plates for any one heat exchanger. When the plates are thus stacked, their respective peripheral edges mutually interlock to form the periphery seal.
- flow channels for a first fluid which alternate with flow channels for a second fluid, are defined, the passage openings 22 respectively defining an inlet duct and an outlet duct for a first fluid, and an inlet conduit and an outlet conduit for a second fluid.
- the herringbone corrugations 26 have in the example an opening angle greater than 90 °, typically 120 °.
- Each of these corrugations comprises two symmetrical branches on either side of the axis XX, each branch extending from this axis XX to the vicinity of a long side 14. It is noted that some of these undulations are interrupted for to define the annular borders 24 which respectively surround the openings 22.
- two rectilinear bosses 28 are provided at the ends of the plate, that is to say respectively close to the narrow sides 16, between the passage openings 22.
- each boss 28 above generates a brazing point that stiffens this area. But, since the same plate must be used, this brazing point must be off-center with respect to the small sides 16 of the plate to come to braze. This off-centering generates a large area without soldering point, alternately on the left side and on the right side, which decreases the mechanical strength of the plate.
- zones Z 1 and Z 2 are also identified in FIG. 2 which represents another plate of the prior art. It is first noted that there are no points of contact in both zones Zi and zones Z 2 .
- Figure 3 shows a plate identical to that of Figure 1 in a rotated position of 180 ° and can therefore be superimposed on the plate of Figure 1. Zones Z 1 and Z 2 are also identified.
- the section of FIG. 4 shows how, in a zone Z 1 #, the corrugations 26 of a top plate 10 are found opposite the hollow generated by this undulation, thus without contact with the bottom 12 of a plate lower, which decreases by a ripple step the line of brazed points, as mentioned previously.
- FIGS. 5 and 6 respectively show the brazing zones created by the bosses 28.
- Figure 7 schematically shows the chevron corrugations 26 and the boss 28 of a plate 10 of the prior art, all shown in fine lines. It is also represented in thick line a portion of the corrugations 26 of an identical plate placed above and 180 ° rotated position. It can be seen that there are lost solder points P identified by small black circles. In the example, there are three points P near each of the openings 22 on the left side and also three points P near each of the openings 22 on the right side.
- the invention overcomes such disadvantages.
- FIG. 8 shows schematically a plate 10 according to the invention which has a structure generally similar to that of a plate 10 of the prior art as described previously.
- the common elements of a plate according to the invention and a plate according to the prior art will therefore be designated by the same numerical references to avoid repetitions.
- the chevron corrugations 26 1 and 26 2 each extend generally between the two long sides 14 of the plate.
- the corrugation 26i is composed of two branches each of which comprises a continuous portion 30i and a discontinuous portion 32 ! .
- the continuous portion 30i extends from the longitudinal axis XX, while its continuous portion 32i extends in the extension of the continuous portion and to a large side 14 of the plate .
- the second corrugation 26 2 comprises, in each of these branches, a continuous portion 30 2 and a discontinuous portion 32 2 . These two portions are in the extension of one another and each extend between the longitudinal axis XX and a large side 14 of the plate. However, in each branch of the second corrugation 26 2 , the discontinuous portion 32 2 extends from the median longitudinal axis XX, whereas the continuous portion 2 extends in the extension of the discontinuous portion and towards a big side of the plate.
- the discontinuous portions 32 1 and 32 2 each comprise an aligned series of recesses and bumps arranged alternately.
- the continuous and discontinuous portions of the same branch have substantially the same length.
- the aforementioned hollows and bumps are schematically represented by broken lines.
- corrugations and other reliefs of the plate of Figure 8 are shown in fine lines, while a portion of the corrugations and reliefs of the upper plate are shown in solid lines.
- FIG. 8 shows that the corrugations of the upper plate now intersect with the additional reliefs formed by the discontinuous portions 32 1 and 32 2 , which makes it possible to create soldering points in areas which previously had no points of contact. brazing.
- FIG. 10 shows the brazing zones obtained with a plate according to FIG. 8 or FIG. 9.
- FIG. 10 shows the brazing zones obtained with a plate according to FIG. 8 or FIG. 9.
- four additional brazing zones Z 3 are distinguished which create points. Additional brazing near the openings 22, thanks to the corrugations 26i and 26 2 .
- Figure 11 shows how additional soldering points are created while reducing their distance to the head of the plate, which increases its mechanical strength in these end regions.
- FIG. 11 shows, by comparison with FIG. 4 of the prior art, how now the corrugations 26 of the upper plate come into contact with the additional reliefs 32 and 32 2 formed by the aforementioned discontinuous portions.
- the plate of the invention comprises other additional reliefs, namely two end bosses 34 situated respectively at the two ends of the plate (towards the short sides 16) and between two passage openings 22.
- These two reliefs 34 each extend symmetrically on either side of the axis of symmetry and have a double wave shape which is similar to that of a W. These two reliefs 34 have the same orientation here.
- the plate of the invention finds application in plate heat exchangers, in which identical plates are used.
