Description

ECHANGEUR THERMIQUE  HEAT EXCHANGER
La présente invention concerne le domaine de l'aéraulique et a en particulier pour objet un échangeur thermique comprenant un ensemble de plaques superposées en un empilement, ainsi qu'un procédé de montage d'un tel échangeur thermique. The present invention relates to the field of aerodynamics and particularly relates to a heat exchanger comprising a set of superimposed plates in a stack, and a method of mounting such a heat exchanger.
Il est connu de réaliser un échangeur thermique comprenant un ensemble de plaques superposées en un empilement, ladite plaque s'étendant sensiblement selon un même plan général et comprenant une pluralité de portions de bordure profilée d'un même type réparties sur le contour de la plaque et destinées à prendre appui sur ou à servir d'appui pour des portions de bordure profilée de même type d'une plaque de même type adjacente à ladite plaque dans l'empilement de plaques superposées.  It is known to produce a heat exchanger comprising a set of superimposed plates in a stack, said plate extending substantially in the same general plane and comprising a plurality of contoured edge portions of the same type distributed over the outline of the plate. and intended to bear on or serve as support for profiled edge portions of the same type of a plate of the same type adjacent to said plate in the stack of superposed plates.
Dans les échangeurs thermiques selon l'état de la technique, l'étanchéité entre les plaques est réalisée par la soudure de deux plaques adjacentes.  In heat exchangers according to the state of the art, the sealing between the plates is achieved by the welding of two adjacent plates.
Cependant, ces soudures ont pour effet de dégrader la continuité de l'étanchéité latérale entre deux plaques adjacentes, ce qui augmente les fuites internes et/ou externe et tend à faire varier l'efficacité de l'échangeur thermique.  However, these welds have the effect of degrading the continuity of the lateral sealing between two adjacent plates, which increases the internal and / or external leakage and tends to vary the efficiency of the heat exchanger.
La présente invention a pour but de résoudre tout ou partie des inconvénients mentionnés ci-dessus.  The present invention aims to solve all or part of the disadvantages mentioned above.

Ces dispositions permettent de lier les plaques entre elles avec une continuité d'étanchéité latérale améliorée et de réaliser une étanchéité dans la circulation des flux transitant dans l'échangeur thermique.  These arrangements make it possible to bond the plates together with an improved lateral sealing continuity and to achieve a seal in the circulation of the flows passing through the heat exchanger.
En outre, la réalisation des premières et secondes surfaces de liaison permet de réaliser une fabrication simple des plaques, par moulage, injection, thermoformage ou emboutissage, suivant le matériau utilisé.  In addition, the realization of the first and second connecting surfaces allows for simple manufacture of the plates, by molding, injection, thermoforming or stamping, depending on the material used.
De p l u s , cette d isposition permet de réal iser une prem ière superposition de conduits dans lesquels un premier flux entre et sort de l'échangeur selon une première direction et une deuxième superposition de conduits dans lesquels un deuxième flux entre et sort de l'échangeur selon une deuxième direction différente de la première direction.  In addition, this deposition makes it possible to achieve a first superposition of ducts in which a first flow enters and leaves the exchanger in a first direction and a second superposition of ducts in which a second flow enters and leaves the exchanger in a second direction different from the first direction.

La figure 10 représente les étapes d'un procédé selon l'invention. Comme illustré à la figure 1 , un échangeur thermique 1 comprend une pluralité de plaques 10, 20 superposées en un empilement 2.  Figure 10 shows the steps of a method according to the invention. As illustrated in FIG. 1, a heat exchanger 1 comprises a plurality of plates 10, 20 superposed in a stack 2.
Chaque plaque 10, 20 s'étend selon un plan général P. Dans le mode de réalisation présenté, l'empilement 2 est obtenu en alternant une plaque d'un premier type 10 avec une plaque d'un deuxième type 20. Chaque plaque 1 0, 20 se présente sous la forme d'un hexagone régulier avec des côtés de même longueur et un contour extérieur 3. Each plate 10, 20 extends in a general plane P. In the embodiment shown, the stack 2 is obtained by alternating a plate of a first type with a plate of a second type 20. Each plate 1 0, 20 is in the form of a regular hexagon with sides of the same length and an outer contour 3.
La figure 2 représente schématiquement une plaque 10, 20 vue de dessus avec des plans de coupe A-A, B-B, et C-C.  Figure 2 schematically shows a plate 10, viewed from above with sectional planes A-A, B-B, and C-C.
Les figures 3 et 4 illustrent respectivement le profil selon ces plans de coupe A-A, B-B, et C-C pour les plaques de premier type 1 0 et pour les plaques de deuxième type 20.  FIGS. 3 and 4 respectively show the profile along these cutting planes A-A, B-B and C-C for the plates of the first type 1 0 and for the plates of the second type 20.
Comme illustré respectivement sur ces deux figures 3 et 4, la plaque de premier type 10 présente deux portions de bordure profilée 1 1 d'un premier type apparentes sur la coupe B-B et réparties sur deux côtés opposés de la plaque hexagonale de premier type 10, et la plaque de deuxième type 20 présente deux portions de bordure profilée 21 d'un même type apparentes sur la coupe B-B et réparties sur deux côtés opposés de la plaque hexagonale de deuxième type 20.  As illustrated respectively in these two figures 3 and 4, the first type plate 10 has two profiled edge portions 1 1 of a first type apparent on the BB section and distributed on two opposite sides of the hexagonal plate of the first type 10, and the second type plate 20 has two profiled edge portions 21 of the same type visible on the section BB and distributed on two opposite sides of the second type hexagonal plate 20.
En outre, chaque portion de bordure profilée 1 1 , 21 de premier type comprend une première surface de liaison 4 et une deuxième surface de liaison 5.  In addition, each profiled edge portion 11, 21 of the first type comprises a first connecting surface 4 and a second connecting surface 5.
Comme illustré à la figure 5, la première surface de liaison 4 et la deuxième surface de liaison 5 sont disposées à deux niveaux verticaux n1 , n2 différents de part et d'autre du plan général P de la plaque 10, 20, et disposées à deux distances différentes d1 , d2 du contour 3 extérieur de la plaque 10, 20.  As illustrated in FIG. 5, the first connecting surface 4 and the second connecting surface 5 are arranged at two different vertical levels n1, n2 on either side of the general plane P of the plate 10, 20, and arranged at two different distances d1, d2 of the outer contour 3 of the plate 10, 20.
Dans le mode de réalisation présenté, la première surface de liaison 4 et la deuxième surface de liaison 5 sont planes et sensiblement parallèles au plan général P de la plaque 10, 20 afin de faciliter la liaison des plaques 10, 20.  In the embodiment shown, the first connecting surface 4 and the second connecting surface 5 are flat and substantially parallel to the general plane P of the plate 10, in order to facilitate the connection of the plates 10, 20.
Cependant, dans un autre mode de réal isation non illustré, la première surface de liaison 4 et la deuxième surface de liaison 5 pourraient avoir un autre profil, par exemple en dent de scie.  However, in another embodiment not illustrated, the first connecting surface 4 and the second connecting surface 5 could have another profile, for example sawtooth.

La plaque de premier type 10, présente en outre deux portions de bordure profilée selon un deuxième type 1 2 apparentes sur la coupe A-A et deux portions de bordure profilée selon un troisième type 13 apparentes sur la coupe C-C. Ces deux autres types de portions de bordure 12, 13 sont eux aussi disposés sur deux côtés opposés de la plaque hexagonale de premier type 10. The plate of the first type 10, furthermore has two profiled edge portions of a second type 1 2 apparent on the AA cut and two profiled edge portions of a third type 13 apparent on the cut CC. These other two types of edge portions 12, 13 are also arranged on two opposite sides of the hexagonal plate of the first type 10.
De même, la plaque de deuxième type 20, présente en outre deux portions de bordure profilée selon un deuxième type 22 apparentes sur la coupe A-A et deux portions de bordure profilée selon un troisième type 23 apparentes sur la coupe C-C.  Similarly, the second type plate 20, furthermore has two profiled edge portions of a second type 22 apparent on the section A-A and two profiled edge portions of a third type 23 apparent on the C-C section.
Ces deux autres types de portions de bordure 22, 23 sont eux aussi disposés sur deux côtés opposés de la plaque hexagonale de deuxième type 20.  These other two types of edge portions 22, 23 are also arranged on two opposite sides of the second type hexagonal plate 20.
L'emplacement de ces différentes bordures est respectivement représenté aux figures 6 et 7 pour la plaque de prem ier type 1 0 et pour la plaque de deuxième type 20.  The location of these different borders is respectively represented in FIGS. 6 and 7 for the first type plate 1 0 and for the plate of second type 20.
En outre, les hauteurs h des portions de bordure de deuxième type 1 2, 22 et les hauteurs des portions de bordure de deuxième type 13, 23 sont sensiblement égales entre elles et sensiblement égales à la moitié de la hauteur H d'une portion de bordure de premier type 1 1 , 21 .  In addition, the heights h border portions of second type 1 2, 22 and the heights of the second type of edge portions 13, 23 are substantially equal to each other and substantially equal to half the height H of a portion of edge of first type 1 1, 21.
Les portions de bordure profilée de deuxième type 12, 22 comprennent une première surface de liaison 4.  The profiled edge portions of second type 12, 22 comprise a first connecting surface 4.
Les portions de bord ure profilée de troisième type 13, 23 comprennent une deuxième surface de liaison 5.  The shaped third-type edge portions 13, 23 comprise a second connecting surface 5.
Chaque portion de bordure profilée de premier type 1 1 , 21 s'étend verticalement de part et d'autre du plan P général de la plaque 10, 20.  Each profiled edge portion of first type 1 1, 21 extends vertically on either side of the general plane P of the plate 10, 20.
Chaque portion de bordure profilée de deuxième type 12, 22 s'étend sensiblement verticalement dans un dem i-plan limité par le plan général P de la plaque 10, 20.  Each profiled edge portion of second type 12, 22 extends substantially vertically in a demi-plane limited by the general plane P of the plate 10, 20.
Chaque portion de bordure profilée de troisième type 13, 23 s'étend sensiblement verticalement dans l'autre demi-plan limité par le plan général P de la plaque 10, 20.  Each profiled edge portion of the third type 13, 23 extends substantially vertically in the other half-plane bounded by the general plane P of the plate 10, 20.
Chaque portion de bordure profilée 21 , 22, 23 de la deuxième plaque 20 est le symétrique de chaque portion de bordure profilée de la première plaque par rapport à un plan de symétrie confondu avec le plan général P pour un plan de coupe déterminé.  Each profiled edge portion 21, 22, 23 of the second plate 20 is symmetrical with each profiled edge portion of the first plate relative to a plane of symmetry coincident with the general plane P for a specific sectional plane.
Ainsi, comme illustré à la figure 5, pour une plaque de premier type 1 0, la première surface de liaison 4 et la deuxième surface de liaison 5 sont destinées à venir au contact respectivement avec une première surface de liaison 4 d'une deuxième plaque adjacente de deuxième type 20 dans l'empilement 2 de plaques superposées, et avec une deuxième surface de liaison 5 d'une troisième plaque adjacente de deuxième type 20 dans l'empilement 2 de plaques superposées formant l'échangeur thermique 1 . Thus, as illustrated in FIG. 5, for a plate of the first type 1 0, the first connecting surface 4 and the second connecting surface 5 are intended to come into contact respectively with a first surface of connection 4 of a second adjacent second type plate 20 in the stack 2 of superposed plates, and with a second connecting surface 5 of a third adjacent second type plate 20 in the stack 2 of superposed plates forming the heat exchanger 1.
De même, pour une plaque de deuxième type 20, la première surface de liaison 4 et la deuxième surface de liaison 5 sont destinées à venir au contact respectivement avec une première surface de liaison 4 d'une deuxième plaque adjacente de premier type 10 dans l'empilement 2 de plaques superposées, et avec une deuxième surface de liaison 5 d'une troisième plaque adjacente de premier type 10 dans l'empilement 2 de plaques superposées formant l'échangeur thermique 1 .  Similarly, for a plate of the second type 20, the first connecting surface 4 and the second connecting surface 5 are intended to come into contact respectively with a first connecting surface 4 of a second adjacent plate of the first type 10 stack 2 of superimposed plates, and with a second connecting surface 5 of a third adjacent plate of first type 10 in the stack 2 of superimposed plates forming the heat exchanger 1.
La figure 9 montre une portion de l'empilement 2 de plaques 10, 20, de l'échangeur thermique 1 représenté à la figure 1 dans lequel la première surface de liaison 4 d'une portion de bordure profilée 12 de deuxième type de plaques de premier type 10 supportent la première surface de liaison 4 d'une bordure profilée 22 de deuxième type de plaques de deuxième type 20.  FIG. 9 shows a portion of the stack 2 of plates 10, 20, of the heat exchanger 1 shown in FIG. 1 in which the first connection surface 4 of a profiled edge portion 12 of the second type of plate of FIG. first type 10 support the first connecting surface 4 of a profiled edge 22 of the second type of second type plates 20.
Selon le mode de réalisation illustré de l'invention, la partie de plaque attenante au contour 3 et en saillie de la portion de bordure profilée 12, 22 est supprimée, ci bien que cette portion de bordure profilée 12, 22 est contigue au contour 3 de la plaque 10, 20.  According to the illustrated embodiment of the invention, the portion of the plate adjoining the contour 3 and protruding from the profiled edge portion 12, 22 is removed, although this profiled edge portion 12, 22 is contiguous to the contour 3 of the plate 10, 20.
Comme illustré sur la figure 5, une paire de plaque comprenant une plaque de premier type 10 et une plaque de deuxième type 20 forme un premier ensemble 100.  As illustrated in FIG. 5, a pair of plates comprising a plate of the first type 10 and a plate of the second type 20 forms a first assembly 100.
Un conduit 8 pour la circulation des flux thermique est formé entre chaque plaque 1 0, 20 de la paire de plaque. Ce conduit 8 a une hauteur sensiblement égale à deux fois la hauteur h d'une portion de bordure de deuxième type 1 2, 22, à deux fois la hauteur h d'une portion de bordure de troisième type 13, 23, ou égal à la hauteur H d'une portion de bordure profilé de premier type 1 1 , 21 .  A duct 8 for the flow of heat flow is formed between each plate 1 0, 20 of the plate pair. This duct 8 has a height substantially equal to twice the height h of a second type of edge portion 1 2, 22, at twice the height h of a third type of edge portion 13, 23, or equal to the height H of a profiled edge portion of the first type 1 1, 21.
Les portions de bordure profilée du deuxième type 12, 22 et du troisième type 13, 23 réparties sur le contour 3 des plaques 10, 20 de l 'empilement 2 présentent des arrond is 6 agencés pour former au moins partiellement un bord d'attaque ou de fuite 9 d'une partie de la plaque 10, 20 par rapport à un flux de fluide destiné à traverser l'échangeur 1 .  The shaped edge portions of the second type 12, 22 and the third type 13, 23 distributed over the contour 3 of the plates 10, 20 of the stack 2 have rounds 6 arranged to form at least partially a leading edge or leakage 9 of a portion of the plate 10, 20 with respect to a flow of fluid for passing through the exchanger 1.
De pl us, chaq ue plaq ue 1 0, 20 présente une continuité des premières surfaces de liaison 4 des portions de bordure profilée du premier type 1 1 , 21 et d'une portion de bordure du deuxième type 12, 22 adjacente, et une continuité des deuxièmes surfaces de liaison 5 des portions de bordure profilée du premier type 1 1 , 21 et d'une portion de bordure du troisième type 13, 23 adjacente afin de conserver l'étanchéité des parois latérales des conduits 8. On the other hand, each plate 1 0, 20 has a continuity of the first connection surfaces 4 of the profiled edge portions of the first type 1 1, 21 and a border portion of the second type 12, 22 adjacent, and a continuity of the second connecting surfaces 5 profiled edge portions of the first type 1 1, 21 and a border portion of the third type 13, 23 adjacent in order to maintain the tightness of the side walls of the ducts 8.
Comme illustré sur cette même figure 5, une pluralité de premiers ensembles 100 forme un deuxième ensemble 200.  As illustrated in this same FIG. 5, a plurality of first sets 100 form a second set 200.
L'empilement 2 alterné de plaq ues de prem ier type 10 et de plaques de deuxième type 20, forme deux séries de passages 8 superposées décalées de 60°.  The alternating stack 2 of plates of the first type 10 and plates of the second type 20 form two series of superimposed passages 8 offset by 60 °.
Comme illustré sur la figure 8, chaque plaque 1 0, 20, sur une surface supérieure mais également inférieure (non illustré), comprend d'une part un premier ensemble de motifs 30 destinés à former des canaux pour faciliter un échange thermique entre un fluide disposé au dessus de ladite plaque 1 0, 20 et un flu ide d isposé en dessous de lad ite plaque 10,20, les motifs 30 étant formés par un ensemble de nervures 31 et de gorges 32 et comprend d'autre part un deuxième ensemble de motifs 40, formant un ensemble de nervures 41 et de gorges 42.  As illustrated in FIG. 8, each plate 1 0, 20, on an upper but also lower surface (not shown), comprises on the one hand a first set of patterns 30 intended to form channels to facilitate a heat exchange between a fluid disposed above said plate 10, 20 and a fluid d isposé below the said plate 10,20, the patterns 30 being formed by a set of ribs 31 and grooves 32 and further comprises a second set of patterns 40, forming a set of ribs 41 and grooves 42.
Les nervures 31 , 41 s'étendent longitudinalement au plan général P de la plaque 10, 20.  The ribs 31, 41 extend longitudinally to the general plane P of the plate 10, 20.
Les motifs d u deuxième ensemble 40 s'étendent dans une première zone de surface 43 se situant entre les deux portions de bordure doubles 1 1 , 21 de la plaque 10, 20.  The patterns of the second set 40 extend in a first surface area 43 lying between the two double edge portions 11, 21 of the plate 10, 20.
Les motifs du premier ensemble 30 occupent quant à eux deux zones de surface 33, 34 situées de part et d'autre de la prem ière zone de surface 43 sur toute la surface restante de la plaque 10, 20.  The patterns of the first set 30 occupy two surface areas 33, 34 located on either side of the first surface area 43 over the entire remaining surface of the plate 10, 20.
Les motifs du premier ensemble 30 sont plus volumineux que ceux du deuxième ensemble 40.  The patterns of the first set 30 are larger than those of the second set 40.
Notamment, les nervures 31 des motifs du premier ensemble 30 présentent une hauteur sensiblement égale à celle des portions de bordure haute 12, 22 ou basse 13, 23 selon la face supérieure ou inférieure considérée de la plaque 10, 20.  In particular, the ribs 31 of the patterns of the first set 30 have a height substantially equal to that of the high edge portions 12, 22 or low 13, 23 according to the upper or lower face considered of the plate 10, 20.
De plus, la disposition des nervures 31 est réalisée de manière à ce que les nervures 31 d'une plaque adjacente dans l'empilement 2 s'appuient ou créaient des points d'appui 7 sur ou pour les nervures 31 de la plaque 10, 20 considérée, renforçant ainsi la cohésion de l'empilement 2 de plaques 10, 20. In addition, the arrangement of the ribs 31 is formed in such a way that the ribs 31 of an adjacent plate in the stack 2 rest or create support points 7 on or for the ribs 31 of the plate 10, 20, thus reinforcing the cohesion of the stack 2 of plates 10, 20.
Chaque nervure 31 s'étend depuis une bordure basse 13, 23, jusqu'à la première zone de surface 43 du deuxième ensemble 40.  Each rib 31 extends from a low border 13, 23, to the first surface area 43 of the second set 40.
Une fois sur deux, l'extrémité de ces nervures 31 la plus proche du contour 3 de la plaque 10, 20 comprend un renflement arrondi 35.  Once in two, the end of these ribs 31 closest to the contour 3 of the plate 10, 20 comprises a rounded bulge 35.
Ces dispositions permettent de préserver un écoulement laminaire limitant les turbulences et donc les pertes de charge dans l'échangeur thermique 1 .  These arrangements make it possible to preserve a laminar flow limiting the turbulence and therefore the pressure drops in the heat exchanger 1.
La présente invention a également pour objet un procédé de montage d'un tel échangeur thermique 1 .  The present invention also relates to a method of mounting such a heat exchanger 1.
