Description

L'invention concerne les échangeurs de chaleur, notamment les radiateurs de refroidissement pour véhicules automobiles, du type comportant une boîte à eau et un vase d'expansion qui lui est raccordé par une tubulure formée d'une seule pièce avec une partie au moins de la boîte à eau et une partie au moins du vase d'expansion, un flotteur appartenant à un indicateur de niveau d'eau étant disposé dans la tubulure.The invention relates to heat exchangers, in particular cooling radiators for motor vehicles, of the type comprising a water box and an expansion tank which is connected to it by a tube formed in one piece with at least a portion of the water box and at least part of the expansion tank, a float belonging to a water level indicator being disposed in the tubing.

Un tel radiateur est décrit dans le document FR-A 2 588 366.Such a radiator is described in document FR-A 2 588 366.

Dans ce type d'échangeur de chaleur, le fonctionnement du flotteur risque d'être perturbé par des tourbillons et des remous provoqués par la circulation des fluides entre la boîte à eau et le vase d'expansion.In this type of heat exchanger, the operation of the float may be disturbed by eddies and eddies caused by the circulation of fluids between the water box and the expansion tank.

Le but de l'invention est d'éviter ces perturbations.The object of the invention is to avoid these disturbances.

Ce but est atteint selon l'invention au moyen d'un déflecteur destiné à être mis en place dans la tubulure, ce déflecteur comprenant des moyens de positionnement par rapport à ladite tubulure, des parois définissant une chambre pour recevoir le flotteur, des moyens pour établir une communication limitée entre ladite chambre d'une part, des moyens définissant une conduite de dégazage pour le passage de bulles de gaz de la boîte à eau au vase d'expansion et des moyens définissant une conduite de circulation de fluide du vase d'expansion vers la boîte à eau.This object is achieved according to the invention by means of a deflector intended to be put in place in the tubing, this deflector comprising means of positioning relative to said tubing, walls defining a chamber for receiving the float, means for establish a limited communication between said chamber on the one hand, means defining a degassing pipe for the passage of gas bubbles from the water box to the expansion tank and means defining a pipe for circulating fluid from the tank expansion to the water box.

Les moyens de positionnement peuvent comprendre au moins une paroi venant en appui contre une paroi de la tubulure. Ils peuvent comprendre, alternativement ou en supplément, au moins une saillie venant en butée contre un épaulement de la boîte à eau et/ou du vase d'expansion à l'extrémité de la tubulure. Avantageusement, une telle saillie peut s'effacer élastiquement lors de la mise en place du déflecteur.The positioning means may comprise at least one wall bearing against a wall of the tube. They may comprise, alternatively or in addition, at least one projection coming into abutment against a shoulder of the water box and / or of the expansion vessel at the end of the tubing. Advantageously, such a projection can be elastically erased when the deflector is put in place.

Selon une autre caractéristique de l'invention, les moyens définissant une conduite de dégazage comprennent un décrochement, vers l'intérieur de la tubulure, d'une paroi de la chambre venant en appui contre une paroi de la tubulure.According to another characteristic of the invention, the means defining a degassing pipe comprise a recess, towards the inside of the tube, of a wall of the chamber coming to bear against a wall of the tube.

L'invention prévoit également que les moyens définissant une conduite de circulation de fluide comprennent une paroi s'étendant longitudinalement dans la tubulure et divisant l'espace intérieur de celle-ci en deux sous-espaces, l'un des sous-espaces contenant la chambre et l'autre sous-espace contenant la conduite de circulation.The invention also provides that the means defining a fluid circulation pipe comprise a wall extending longitudinally in the tubing and dividing the interior space thereof into two subspaces, one of the subspaces containing the room and the other subspace containing the circulation pipe.

L' invention sera décrit ci-après plus en détail à l'aide d'un exemple préféré de réalisation, et des dessins annexés, dans lesquels:

  • - la figure 5 est une vue de côté du déflecteur.
The invention will be described below in more detail with the aid of a preferred embodiment, and the accompanying drawings, in which:
  • - Figure 1 is a partial view of a radiator according to the invention, in section along line II of Figure 2;
  • - Figure 2 is a partial top view of the radiator;

  • - Figure 4 is a section of the deflector along the line IV-IV of Figure 1;
  • - Figure 5 is a side view of the deflector.

Le radiateur partiellement illustré à la figure 1, destiné au refroidissement du moteur d'un véhicule automobile, comprend une boîte à eau 1 disposée verticalement, associée à un collecteur 2 sous forme d'une plaque également verticale présentant une multiplicité de trous dans lesquels s'engagent de façon étanche les extrémités de tubes 3. Les tubes 3, disposés horizontalement, sont destinés à la circulation d'un liquide de refroidissement. Les tubes 3 traversent des ailettes 4 parallèles au collecteur 2, avec lesquelles ils sont en contact thermique.The radiator partially illustrated in Figure 1, for cooling the engine of a motor vehicle, comprises a water box 1 arranged vertically, associated with a collector 2 in the form of a plate also vertical having a multiplicity of holes in which s 'tightly engage the ends of tubes 3. The tubes 3, arranged horizontally, are intended for the circulation of a cooling liquid. The tubes 3 pass through fins 4 parallel to the manifold 2, with which they are in thermal contact.

Au-dessus du radiateur proprement dit, et notamment au-dessus de la boîte à eau 1, se trouve un vase d'expansion 5. La boîte à eau 1 et le vase d'expansion 5 sont reliés par une tubulure 7 formée d'une seule pièce, par exemple par injection de matière plastique, avec les parties de la boîte à eau et du vase d'expansion auxquelles elle se raccorde.Above the radiator proper, and in particular above the water box 1, is an expansion tank 5. The water box 1 and the expansion tank 5 are connected by a tube 7 formed of a single piece, for example by plastic injection, with the parts of the water box and the expansion tank to which it is connected.

Dans la paroi de la tubulure 7 est monté un détecteur de niveau de liquide 8 comportant un flotteur 9 disposé à l'intérieur de la tubulure. Le détecteur est par exemple du type comprenant un contact électrique influencé par un aimant porté par le flotteur, tel que décrit dans le document FR-A 2 506 012. Le détecteur 8 est relié à un voyant placé au tableau de bord du véhicule.In the wall of the tubing 7 is mounted a liquid level detector 8 comprising a float 9 disposed inside the tubing. The detector is for example of the type comprising an electrical contact influenced by a magnet carried by the float, as described in the document FR-A 2 506 012. The detector 8 is connected to an indicator placed on the dashboard of the vehicle.

Selon l'invention, un déflecteur 10 est mis en place dans la tubulure 7 pour protéger le flotteur 9 contre les turbulences dues aux échanges de fluides entre la boîte à eau 1 et le vase d'expansion 5.According to the invention, a deflector 10 is placed in the tubing 7 to protect the float 9 against turbulence due to the exchange of fluids between the water box 1 and the expansion tank 5.

Le déflecteur 10 comprend, comme on le voit plus particulièrement à la figure 4, une portion de paroi 11 s'étendant selon la direction longitudinale de la tubulure 7, laquelle est légèrement incurvée, et tapissant la paroi de la tubulure, représentée en traits mixtes et notée 12 à la figure 4, sur une fraction de son périmètre. Une autre portion de paroi 13 du déflecteur, s'étendant également longitudinalement par rapport à la tubulure, partage l'espace interne de celle-ci en deux sous-espaces 14 et 15. Les portions de paroi 11 et 13 se raccordent entre elles en 16, la portion de paroi 11 présentant, à l'opposé de la jonction 16, un bord longitudinal libre 17.The deflector 10 comprises, as can be seen more particularly in FIG. 4, a wall portion 11 extending in the longitudinal direction of the tube 7, which is slightly curved, and lining the wall of the tube, shown in phantom and noted 12 in Figure 4, on a fraction of its perimeter. Another wall portion 13 of the deflector, also extending longitudinally with respect to the tube, divides the internal space of the latter into two subspaces 14 and 15. The wall portions 11 and 13 are connected to each other in 16, the wall portion 11 having, opposite the junction 16, a free longitudinal edge 17.

Le déflecteur 10 présente également une paroi supérieure 18 et une paroi inférieure 19 séparant l'intérieur de la tubulure de celui du vase d'expansion et de celui de la boîte à eau respectivement. Les parois extrêmes 18 et 19 se raccordent aux portions de parois 11 et 13 pour définir, en coopération avec ces dernières et avec la portion de la paroi 12 de la tubulure comprise entre le bord libre 17 de la portion de paroi 11 et le bord libre 20 de la portion de paroi 13 une chambre 21 contenue dans le sous-espace 14 et dans laquelle se trouve le flotteur 9. La chambre 21 est en communication limitée avec le vase d'expansion 5 et avec la boîte à eau 1 par des encoches 22 et 23 ménagées dans les parois 18 et 19 respectivement.The deflector 10 also has an upper wall 18 and a lower wall 19 separating the interior of the tubing from that of the expansion tank and that of the water box respectively. The end walls 18 and 19 are connected to the portions of walls 11 and 13 to define, in cooperation with the latter and with the portion of the wall 12 of the pipe included between the free edge 17 of the wall portion 11 and the free edge 20 of the wall portion 13 a chamber 21 contained in the subspace 14 and in which the float 9 is located. The chamber 21 is in limited communication with the expansion tank 5 and with the water box 1 by notches 22 and 23 formed in the walls 18 and 19 respectively.

La portion de paroi 11 du déflecteur s'écarte de la paroi 12 de la tubulure, sur une petite fraction de son extension circonférentielle, pour former, entre la portion de paroi 11 et la paroi 12, une conduite longitudinale 24 reliant la boîte à eau et le vase d'expansion. Cette conduite 24, dite conduite de dégazage, qui s'étend le long de la paroi de la tubulure dans la zone où sa courbure longitudinale tourne sa convexité vers l'intérieur, permet aux bulles de gaz qui se rassemblent à la partie supérieure de la boîte à eau 1 de passer dans le vase d'expansion 5.The wall portion 11 of the deflector moves away from the wall 12 of the tube, over a small fraction of its circumferential extension, to form, between the wall portion 11 and the wall 12, a pipe lon gitudinal 24 connecting the water box and the expansion tank. This pipe 24, called degassing pipe, which extends along the wall of the pipe in the area where its longitudinal curvature turns its convexity inwards, allows the gas bubbles which collect at the upper part of the water box 1 to pass into the expansion tank 5.

Le sous-espace 15 délimité par la portion de paroi 13, qui communique librement avec la boîte à eau d'une part et le vase d'expansion d'autre part, constitue une conduite de circulation de liquide du vase d'expansion vers la boîte à eau. Cette conduite est partagée en deux par une nervure de renforcement 25 dépendant de la paroi 13 et dont la crête s'appuie contre la paroi 12 de la tubulure, cette nervure s'étendant longitudinalement en suivant la courbure de la tubulure.The subspace 15 delimited by the wall portion 13, which communicates freely with the water box on the one hand and the expansion tank on the other hand, constitutes a liquid circulation pipe from the expansion tank to the water box. This pipe is divided in two by a reinforcing rib 25 depending on the wall 13 and the crest of which rests against the wall 12 of the tube, this rib extending longitudinally following the curvature of the tube.

La portion de paroi 11 du déflecteur, le bord libre 20 de la portion de paroi 13 et la crête de la nervure 25,en s'appuyant contre la paroi 12 de la tubulure, assurent un positionnement transversal du déflecteur dans cette dernière. La paroi supérieure 18, qui s'étend à l'extrémité supérieure de la tubulure 7, s'appuie par un prolongement 26 sur un épaulement 27 formé par la paroi du vase d'expansion à l'en droit où il se raccorde à la tubulure. Cette butée empêche le déflecteur de se déplacer vers le bas. Une saillie 28 prolongeant vers le bas la nervure 25 s'appuie sur la paroi 29 de la boîte à eau 1 à l'endroit où elle se raccorde à la tubulure. Cette butée empêche le déflecteur de se déplacer vers le haut. La saillie 28 peut s'effacer élastiquement pour permettre l'introduction du déflecteur par le haut.The wall portion 11 of the deflector, the free edge 20 of the wall portion 13 and the crest of the rib 25, pressing against the wall 12 of the tube, ensure transverse positioning of the deflector in the latter. The upper wall 18, which extends at the upper end of the tubing 7, is supported by an extension 26 on a shoulder 27 formed by the wall of the expansion vessel at right where it is connected to the tubing. This stop prevents the deflector from moving down. A projection 28 extending downward the rib 25 is supported on the wall 29 of the water box 1 at the place where it is connected to the tubing. This stop prevents the deflector from moving up. The projection 28 can be elastically erased to allow the introduction of the deflector from above.

D'autres nervures de renforcement sont prévues sur les parois d'extrémité 18 et 19 du déflecteur.Other reinforcing ribs are provided on the end walls 18 and 19 of the deflector.
