Other characteristics and advantages of the invention will appear on examining the detailed description below, and the appended drawings, in which:
  • Figures 1, 2 and 3 are respectively front, side and top views of a motor vehicle radiator according to the invention.

Le radiateur illustré est un radiateur à circulation verticale et comprend un faisceau de tubes 1 composé d'une série de tubes verticaux et d'une série d'ailettes horizontales 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 is a vertical circulation radiator and comprises a bundle of tubes 1 composed of a series of vertical tubes and a series of horizontal fins not shown in detail, an upper water box 2 and a lower water box 3, elongated 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 elongated vertically, assembled to the water boxes by their end regions and laterally framing the beam 1.

La boîte à eau supérieure 2 est une pièce moulée en forme de bac allongé ouvert vers le bas, présentant des parois longitudinales avant et arrière (par rapport à la figure 1) 6 et 7 semsiblement verticales, une paroi supérieure ou de fond 8 sensiblement semi- cylindrique, ainsi que des parois d'extrémités. L'ouverture inférieure du bac est obturée par une plaque collectrice perforée 9 traversée par les extrémités supérieures des tubes du faisceau 1.The upper water box 2 is a molded part in the shape of an elongated tank open downwards, having longitudinal front and rear walls (with respect to FIG. 1) 6 and 7 semi-vertically, an upper or bottom wall 8 substantially semi - cylindrical, as well as end walls. The lower opening of the tank is closed by a perforated collecting plate 9 crossed by the upper ends of the tubes of the bundle 1.

Une patte 10 sous forme de plaque horizontale, allongée dans la direction longitudinale de la boîte à eau 2, c'est-à-dire dans la direction latérale du radiateur, s'étend vers l'arrière à partir de la paroi 8, à l'extérieur du bac. La patte 10 est reliée à la paroi arrière 7 par des nervures de renforcement verticales 11. Elle est percée de quatre ouvertures identiques 12 ayant une section rectangulaire allongée dans la direction longitudinale de la boîte à eau, d'environ 2 cm x 1 cm. Ces ouvertures sont mutuellement alignées dans la direction longitudinale de la boîte à fluide et sont écartées de quelques millimètres du bord arrière 13 de la patte 10. Chacune des ouverture 12, indépendamment des autres, peut être utilisée pour la fixation d'un anneau de guidage de flexible.A tab 10 in the form of a horizontal plate, elongated in the longitudinal direction of the water box 2, that is to say in the lateral direction of the radiator, extends rearwards from the wall 8, the outside of the tank. The tab 10 is connected to the rear wall 7 by vertical reinforcing ribs 11. It is pierced by four identical openings 12 having a rectangular section elongated in the longitudinal direction of the water box, of about 2 cm x 1 cm. These openings are mutually aligned in the longitudinal direction of the fluid box and are spaced a few millimeters from the rear edge 13 of the tab 10. Each of the openings 12, independently of the others, can be used for fixing a hose guide ring.

La boîte à eau 2 présente également une patte 14 faisant saillie vers l'avant, traversée par un trou 15 pour la fixation du radiateur sur le châssis du véhicule, et raccordée à la paroi avant 6 par des nervures de renforcement verticales 16.The water box 2 also has a lug 14 projecting forward, through which a hole 15 is fixed for fixing the radiator to the chassis of the vehicle, and connected to the front wall 6 by vertical reinforcing ribs 16.

La boîte à eau inférieure 3 a une structure générale analogue à celle de la boîte à eau supérieure 2, et présente une paroi avant 17, une paroi arrière 18, une paroi inférieure 19 et des parois d'extrémités. Elle est associée à une plaque collectrice 20.The lower water box 3 has a general structure similar to that of the upper water box 2, and has a front wall 17, a rear wall 18, a lower wall 19 and end walls. It is associated with a collecting plate 20.

Deux pattes 21 et 22 font saillie extérieurement vers l'arrière à partir de la paroi 19, respectivement dans les deux régions d'extrémités de la boîte à eau 3. Chacune des pattes 21 et 22 est traversée par un trou 23 et peut servir, au choix, pour la fixation d'un support de batterie.Two legs 21 and 22 project outwardly rearward from the wall 19, respectively in the two end regions of the water box 3. Each of the legs 21 and 22 is crossed by a hole 23 and can be used, optionally for attaching a battery holder.

Chacune des pattes 10,14,21 et 22 présente une face supérieure sensiblement plane et horizontale.Each of the tabs 10, 14, 21 and 22 has a substantially planar and horizontal upper face.

La boîte à eau inférieure 3 forme également deux plaques 24 et 25 faisant saillie vers le bas respectivement à partir de ses deux parois d'extrémités. Chacune de ces plaques est composée d'une semelle mince 26 orientée verticalement et d'un réseau de nervures et de bossages 27 s'étendant à partir de celle-ci vers l'extérieur dans la direction longitudinale de la boîte à eau et se terminant dans un même plan vertical 28 perpendiculaire à la direction longitudinale de la boîte à eau. Les sommets des nervures et bossages 27 de chaque plaque 24, 25 définissent ainsi une surface d'appui plane par laquelle la boîte à eau peut être posée de façon stable sur un support horizontal avant son montage. Les plaques 24 et 25 s'étendent vers l'arrière jusqu'aux bords arrière des pattes 21 et 22 et se raccordent à celles-ci à la fois directement et par des nervures de renforcement 29.The lower water box 3 also forms two plates 24 and 25 projecting downwards respectively from its two end walls. Each of these plates is composed of a thin sole 26 oriented vertically and of a network of ribs and bosses 27 extending therefrom outward in the longitudinal direction of the water box and ending in the same vertical plane 28 perpendicular to the longitudinal direction of the water box. The tops of the ribs and bosses 27 of each plate 24, 25 thus define a flat bearing surface by which the water box can be stably placed on a horizontal support before it is mounted. The plates 24 and 25 extend rearward to the rear edges of the lugs 21 and 22 and are connected to these both directly and by reinforcing ribs 29.
