Abstract

The cross-member (4) joins together the two headers (2,3) of the radiator and extends along one side (22) of the bundle of tubes (1). Various sequences of holes, distributed along the cross-member, allow it to be fastened to one (3) of the headers at different locations, in order to obtain radiators with different heights. Flaps (28,29) cut out from the base of the cross-member can be folded towards the bundle in order to block the passage of air between the latter and the base, when the fastening location used is different from the one furthest from the end of the cross-member. <IMAGE>

Description

L'invention concerne une traverse allongée pour échangeur de chaleur destinée à s'étendre le long d'un flanc d'un faisceau de tubes, parallèlement aux tubes, en étant assemblée dans l'une de ses régions d'extrémités à une boîte à fluide allongée s'étendant transversalement au faisceau et dans laquelle débouchent les extrémités des tubes.The invention relates to an elongated cross member for a heat exchanger intended to extend along a flank of a bundle of tubes, parallel to the tubes, being assembled in one of its end regions to a box. elongated fluid extending transversely to the bundle and into which the ends of the tubes open.

De telles traverses sont utilisées en particulier pour le montage de radiateurs de grandes dimensions pour le refroidissement des moteurs de véhicules industriels, qui, en raison de leur coût élevé, doivent être démontables pour des réparations éventuelles.Such crosspieces are used in particular for mounting large radiators for cooling the engines of industrial vehicles, which, because of their high cost, must be removable for possible repairs.

Il est connu d'utiliser les mêmes boîtes à fluide et les mêmes ailettes de refroidissement pour des radiateurs ayant des capacités de refroidissement différentes. Les radiateurs diffèrent alors entre eux par la longueur des tubes et par conséquent des traverses, ce qui conduit à prévoir différents modèles de traverses.It is known to use the same fluid boxes and the same cooling fins for radiators having different cooling capacities. The radiators then differ from each other by the length of the tubes and consequently of the crosspieces, which leads to the provision of different models of crosspieces.

Le but de l'invention est de réduire encore le nombre de pièces différentes nécessaires pour la réalisation des différentes tailles d'échangeurs de chaleur.The object of the invention is to further reduce the number of different parts necessary for the production of the different sizes of heat exchangers.

A cet effet, l'invention prévoit sur la traverse au moins deux emplacements munis de moyens d'assemblage, écartés l'un de l'autre le long de ladite région d'extrémité et utilisables au choix pour l'assemblage avec la boîte à fluide pour réaliser des échangeurs de chaleur de longueurs différentes.To this end, the invention provides on the cross member at least two locations provided with assembly means, spaced from one another along said end region and which can be used as desired for assembly with the box. fluid to produce heat exchangers of different lengths.

Des caractéristiques optionnelles avantageuses de la traverse selon l'invention sont énoncées ci-après :

  • - Elle comprend une semelle plate propre à s'appuyer sur ledit flanc du faisceau.
  • - La semelle se raccorde à deux ailes longitudinales tournées à l'opposé de sa surface de contact avec le faisceau, conférant à la traverse un profil en U.
  • - Dans ladite région d'extrémité, la semelle est décalée de façon à s'éloigner de la surface de contact avec le faisceau pour permettre le logement d'une boîte à fluide de longueur supérieure à la largeur du faisceau.
  • - Au moins un volet sensiblement rectangulaire, dont un côté orienté dans la direction longitudinale de la traverse a une longueur sensiblement égale au pas entre deux emplacements d'assemblage, est découpé dans la partie décalée de la semelle de façon à pouvoir se plier, selon ledit côté, pour s'étendre soit dans le plan de ladite partie décalée, en regard de la boîte à fluide, lorsque celui des deux emplacements le plus éloigné de l'extrémité de la traverse est utilisé, soit transversalement à ce plan en direction du flanc du faisceau, pour barrer le passage de l'air entre celui-ci et la partie décalée, lorsque l'emplacement le plus proche de l'extrémité est utilisé.
Advantageous optional characteristics of the crosspiece according to the invention are set out below:
  • - It includes a flat sole suitable for resting on said side of the beam.
  • - The sole is connected to two longitudinal wings turned away from its contact surface with the beam, giving the crossmember a U-shaped profile.
  • - In said end region, the sole is offset so as to move away from the contact surface with the bundle to allow the housing of a fluid box of length greater than the width of the bundle.
  • - At least one substantially rectangular flap, one side oriented in the longitudinal direction of the cross member has a length substantially equal to the pitch between two assembly locations, is cut in the offset part of the sole so as to be able to bend, according said side, to extend either in the plane of said offset part, opposite the fluid box, when that of the two locations furthest from the end of the cross member is used, or transversely to this plane in the direction of side of the beam, to block the passage of air between it and the offset part, when the location closest to the end is used.

La totalité de l'air doit alors traverser le faisceau, améliorant ainsi l'échange thermique. De plus la traverse peut s'appliquer sur le faisceau sensiblement sur toute la longueur de celui-ci, renforçant la rigidité de l'assemblage.

  • - Il est prévu au moins trois emplacements d'assemblage et autant de volets repliables que d'emplacements, moins un, sensiblement alignés et juxtaposés dans la direction longitudinale de la traverse.
  • - Les moyens d'assemblage comprennent des trous traversant la semelle et propres à recevoir des vis se vissant dans la boîte à fluide.
All of the air must then pass through the beam, thereby improving heat exchange. In addition the cross can be applied to the beam substantially over the entire length thereof, reinforcing the rigidity of the assembly.
  • - There are at least three assembly locations and as many foldable flaps as there are locations, at least one, substantially aligned and juxtaposed in the longitudinal direction of the cross member.
  • - The assembly means comprise holes passing through the sole and suitable for receiving screws which are screwed into the fluid box.

L'invention vise également un échangeur de chaleur comprenant un faisceau de tubes dont les extrémités des tubes débouchent dans au moins une boîte à fluide, et au moins une traverse telle que définie ci- dessus s'étendant le long d'un flanc du faisceau et assemblée à la boîte à fluide en l'un de ses emplacements d'assemblage.The invention also relates to a heat exchanger comprising a bundle of tubes, the ends of the tubes of which open into at least one fluid box, and at least one cross member as defined above extending along a side of the bundle and assembled to the fluid box at one of its assembly locations.

Un tel échangeur de chaleur peut notamment comprendre deux traverses s'étendant le long des deux flancs opposés du faisceau respectivement et assemblées à la boîte à fluide chacune en l'un de ses emplacements d'assemblage.Such a heat exchanger may in particular comprise two crosspieces extending along the two opposite sides of the bundle respectively and assembled with the fluid box each at one of its assembly locations.

  • - la figure 2 est une vue correspondant à la figure 1, montrant l'une des deux traverses du radiateur, à plus grande échelle ;

  • - la figure 4 est une vue en coupe selon la ligne IV-IV de la figure 3, à plus grande échelle.
Other characteristics and advantages of the invention will appear on examining the detailed description below, and the appended drawings, in which:
  • - Figure 1 is an elevational view of an industrial vehicle radiator according to the invention;
  • - Figure 2 is a view corresponding to Figure 1, showing one of the two cross members of the radiator, on a larger scale;
  • - Figure 3 shows the cross member of Figure 2, as seen from the side of the radiator; and
  • - Figure 4 is a sectional view along the line IV-IV of Figure 3, on a larger scale.

Le radiateur illustré à la figure 1 comprend un faisceau de tubes 1 composé d'une série de tubes verticaux et d'une série d'ailettes non représentés en détail, une boîte à eau supérieure 2 et une boîte à eau inférieure 3, allongées horizontalement dans la direction latérale du faisceau 1 et dans lesquelles débouchent respectivement les extrémités supérieures et les extrémités inférieures des tubes, et deux traverses 4 et 5 allongées verticalement, assemblées aux boîtes à eau par leurs régions d'extrémités et encadrant latéralement le faisceau 1.The radiator illustrated in FIG. 1 comprises a bundle of tubes 1 composed of a series of vertical tubes and a series of fins not shown in detail, an upper water box 2 and a lower water box 3, extended horizontally in the lateral direction of the bundle 1 and into which the upper ends and the lower ends of the tubes open respectively, and two cross members 4 and 5 vertically elongated, assembled to the water boxes by their end regions and laterally framing the bundle 1.

Les traverses 4 et 5 ont la même structure et sont symétriques l'une de l'autre par rapport à un plan vertical médian du radiateur. Seule la traverse 4 sera décrite en se référant aux figures 2 à 4. Cette traverse est formée par une bande de tôle métallique pliée selon deux lignes longitudinales parallèles pour former une semelle 6 et deux ailes 7 et 8. Dans la région d'extrémité supérieure de la traverse, les deux ailes et les zones marginales, adjacentes à celles-ci, de la semelle sont éliminées par des découpes latérales 9 et 10 pour ne laisser subsister qu'une zone médiane 11 de la semelle. Cette zone résiduelle est d'abord pliée sensiblement à angle droit, à partir du plan de base P de la semelle et du même côté de celui-ci que les ailes, selon une ligne sensiblement transversale 12 pour former un décrochement 13, puis pliée de nouveau sensiblement à angle droit selon une autre ligne transversale 14 pour former une portion sensiblement plane 15 sensiblement parallèle au plan P et s'étendant vers le haut, c'est-à-dire à l'opposé de la portion principale de la semelle, par rapport au décrochement 13.The crosspieces 4 and 5 have the same structure and are symmetrical to each other with respect to a vertical median plane of the radiator. Only the cross-member 4 will be described with reference to FIGS. 2 to 4. This cross-member is formed by a strip of metal sheet folded along two parallel longitudinal lines to form a sole 6 and two wings 7 and 8. In the upper end region of the crossmember, the two wings and the marginal zones, adjacent thereto, of the sole are eliminated by lateral cutouts 9 and 10 so as to leave only a median zone 11 of the sole. This residual area is first folded substantially at a right angle, from the base plane P of the sole and on the same side thereof as the wings, along a substantially transverse line 12 to form a recess 13, then folded again substantially at right angles along another transverse line 14 to form a substantially flat portion 15 substantially parallel to the plane P and extending upward, that is to say opposite to the main portion of the sole, compared to the drop 13.

La région d'extrémité inférieure de la traverse présente la même configuration qui vient d'être décrite pour la région d'extrémité supérieure, à ceci près que les découpes latérales 16,17 n'éliminent pas toute la largeur des ailes 7 et 8, mais seulement la zone marginale de celle-ci adjacente à la semelle. Les portions résiduelles des ailes s'étendent, dans les mêmes plans que les parties principales de celles-ci, jusqu'au droit de l'extrémité inférieure de la région décalée inférieure 18 de la semelle, laquelle s'étend parallèlement au plan P et est raccordée à la partie principale de la semelle par un décrochement 19.The lower end region of the cross member has the same configuration which has just been described for the upper end region, except that the lateral cutouts 16, 17 do not eliminate the entire width of the wings 7 and 8, but only the marginal zone thereof adjacent to the sole. The residual portions of the wings extend, in the same planes as the main parts thereof, up to the right of the lower end of the lower offset region 18 of the sole, which extends parallel to the plane P and is connected to the main part of the sole by a recess 19.

La région décalée supérieure 15 de la semelle est traversée par deux trous 20 disposés symétriquement l'un de l'autre par rapport à un plan longitudinal médian. Ces trous servent à assembler la traverse à la boîte à eau supérieure 2, qui présente à cet effet un bossage 21 faisant saillie sur sa paroi d'extrémité (figure 1) et comportant une surface d'appui plane pour la région 15, décalée vers l'extérieur du radiateur par rapport au plan du flanc correspondant 22 du faisceau de tubes 1. L'assemblage est réalisé au moyen de vis qui s'engagent dans les trous 20 et se vissent dans le bossage 21, et dont les têtes appliquent la région 15 de la semelle contre la surface d'appui du bossage. L'assemblage de la traverse sur la boîte à eau inférieure 3 est réalisée de la même façon que sur la boîte à eau 2, grâce à deux trous 23 traversant la région décalée inférieure 18 de la semelle et disposés symétriquement l'un de l'autre par rapport au plan longitudinal médian, et à un bossage 24 faisant saillie sur la paroi d'extrémité de la boîte à eau 3.The upper offset region 15 of the sole is crossed by two holes 20 arranged symmetrically with respect to one another with respect to a median longitudinal plane. These holes are used to assemble the crosspiece to the upper water box 2, which for this purpose has a boss 21 projecting from its end wall (FIG. 1) and comprising a planar bearing surface for region 15, offset towards the outside of the radiator with respect to the plane of the corresponding side 22 of the bundle of tubes 1. The assembly is carried out by means of screws which engage in the holes 20 and are screwed into the boss 21, and whose heads apply the region 15 of the sole against the bearing surface of the boss. The assembly of the crosspiece on the lower water box 3 is carried out in the same way as on the water box 2, by means of two holes 23 passing through the lower offset region 18 of the sole and arranged symmetrically one of the other with respect to the median longitudinal plane, and to a boss 24 projecting from the end wall of the water box 3.

Selon l'invention, la portion 18 présente deux autres paires de trous 25 et 26 respectivement, dont les positions se déduisent de celles des trous 23 par des translations dans la direction longitudinale de la traverse et vers le haut. Les paires de trous 23, 25 et 26 définissent trois emplacements d'assemblage permettant de monter la même boîte à eau 3 sur la même traverse 4 à des distances décroissantes de la boîte à eau supérieure 2, pour réaliser des radiateurs de hauteurs décroissantes.According to the invention, the portion 18 has two other pairs of holes 25 and 26 respectively, the positions of which are deduced from those of the holes 23 by translations in the longitudinal direction of the cross member and upwards. The pairs of holes 23, 25 and 26 define three assembly locations making it possible to mount the same water box 3 on the same crosspiece 4 at decreasing distances from the upper water box 2, to produce radiators of decreasing heights.

Les décalages des régions 15 et 18 de la semelle par rapport au plan de base P de celui-ci, qui peuvent être inégaux, correspondent aux décalages des faces d'appui des bossages 21 et 24 des boîtes à eau par rapport au plan du flanc 22 du faisceau de tubes, ce qui permet à la semelle de venir pratiquement en appui sur ce dernier plan. En revanche le décrochement 19, prévu pour permettre le logement de l'extrémité de la boîte à eau 3, y compris du collecteur 27 qui constitue la paroi supérieure de celle-ci, lorsque la paire de trous supérieure 26 de la région 18 est utilisée pour l'assemblage, se trouve à une distance appréciable au-dessus du collecteur 27 lorsque la paire de trous 23 ou la paire de trous 25 est utilisée. Il se forme alors un espace libre limité vers le haut par le décrochement 19, vers le bas par le collecteur 27, vers la gauche par le flanc 22 et vers la droite par la portion de semelle 18. Pour éviter que de l'air passe dans cet espace libre au lieu de traverser le faisceau 1, diminuant ainsi l'efficacité du radiateur, ou au moins pour limiter ce passage d'air, il est prévu deux volets 28 et 29 découpés dans la tôle de la région 18 de la semelle et reliés à celle-ci respectivement pas deux lignes de pliage 30 et 31 mutuellement alignées dans la direction longitudinale de la traverse. Ces deux volets ont une forme rectangulaire dont la ligne 30, 31 constitue l'un des côtés, et s'inscrivent, avant d'être pliés hors du plan de la région 18, dans une découpe rectangulaire 32 de largeur légèrement supérieure à la largeur de chaque volet et de hauteur légèrement supérieure à la somme des hauteurs de ceux-ci, comme indiqué en trait mixte à la figure 3. La largeur des volets est sensiblement égale à la distance entre le plan P et le plan de la région 18, de telle sorte que, quand ils sont pliés à 90° en direction du plan P, comme montré aux figures 1, 2 et 4, leurs bords 33 et 34, opposés aux lignes de pliage 30 et 31, sont situés sensiblement dans ce plan. Par ailleurs les bords supérieurs 35 et 36 de la découpe 32 et du volet 29 sont très proches du décrochement 19, et les hauteurs des volets 28 et 29 correspondent respectivement aux entr'axes entre les trous 23 et 25 et entre les trous 25 et 26 respectivement. Lorsque les deux volets sont ainsi pliés, comme montré à la figure 1, ils s'étendent en travers de l'espace libre décrit plus haut, sur la majeure partie de la section de passage d'air correspondante. Le même résultat est obtenu en pliant le seul volet 29 perpendiculairement au plan P lorsque la boîte à eau 3 est assemblée à la traverse en utilisant les trous 25.The offsets of the regions 15 and 18 of the sole with respect to the base plane P thereof, which may be unequal, correspond to the offsets of the bearing faces of the bosses 21 and 24 of the water boxes relative to the plane of the sidewall 22 of the tube bundle, which allows the sole to come to bear practically on this latter plane. On the other hand the recess 19, provided to allow the housing of the end of the water box 3, including the collector 27 which constitutes the upper wall thereof, when the pair of upper holes 26 of the region 18 is used for assembly, is at a considerable distance above the manifold 27 when the pair of holes 23 or the pair of holes 25 is used. A free space is then formed, limited upwards by the recess 19, downwards by the manifold 27, to the left by the flank 22 and to the right by the sole portion 18. To prevent air from passing in this free space instead of crossing the beam 1, thereby reducing the efficiency of the radiator, or at least to limit this passage of air, two flaps 28 and 29 are provided cut out from the sheet of the region 18 of the soleplate and connected thereto respectively by two fold lines 30 and 31 mutually aligned in the longitudinal direction of the crosspiece. These two flaps have a rectangular shape whose line 30, 31 constitutes one of the sides, and are inscribed, before being folded out of the plane of the region 18, in a rectangular cutout 32 of width slightly greater than the width of each flap and of height slightly greater than the sum of the heights of these, as indicated in phantom in Figure 3. The width of the flaps is substantially equal to the distance between the plane P and the plane of the region 18, so that, when they are folded at 90 ° in the direction of the plane P, as shown in FIGS. 1, 2 and 4, their edges 33 and 34, opposite the fold lines 30 and 31, are situated substantially in this plane. Furthermore, the upper edges 35 and 36 of the cutout 32 and of the flap 29 are very close to the recess 19, and the heights of the flaps 28 and 29 correspond respectively to the axes between the holes 23 and 25 and between the holes 25 and 26 respectively. When the two flaps are thus folded, as shown in FIG. 1, they extend across the free space described above, over the major part of the corresponding air passage section. The same result is obtained by folding the single flap 29 perpendicular to the plane P when the water box 3 is assembled to the cross-member using the holes 25.
