Abstract
Description
L'invention concerne un ensemble rigide comprenant un premier échangeur de chaleur de forme générale plate, comportant au moins une boîte à fluide supérieure en matière plastique, et un vase d'expansion en relation d'échange de fluide avec la boîte à fluide supérieure, situé à proximité de celle-ci.The invention relates to a rigid assembly comprising a first heat exchanger of generally flat shape, comprising at least one upper fluid box made of plastic material, and an expansion vessel in fluid exchange relationship with the upper fluid box, located near it.
De tels ensembles sont notamment utilisés dans les véhicules automobiles, le premier échangeur de chaleur et le vase d'expansion faisant partie d'un circuit de fluide de refroidissement du moteur thermique du véhicule. Dans le cas d'un véhicule de tourisme, le vase d'expansion peut être formé d'une seule pièce avec la boîte à fluide supérieure, ou fixé directement sur celle-ci. Pour les véhicules industriels et agricoles, compte tenu de la grande quantité de fluide que doit recevoir le vase d'expansion, cette solution nécessiterait un renforcement considérable de la boîte à fluide pour qu'elle puisse résister aux efforts exercés par le vase d'expansion du fait de son propre poids et des accélérations du véhicule.Such assemblies are used in particular in motor vehicles, the first heat exchanger and the expansion tank forming part of a coolant circuit of the vehicle's heat engine. In the case of a passenger vehicle, the expansion tank can be formed in one piece with the upper fluid box, or fixed directly to the latter. For industrial and agricultural vehicles, given the large amount of fluid that the expansion tank must receive, this solution would require a considerable strengthening of the fluid box so that it can resist the forces exerted by the expansion tank. due to its own weight and the vehicle's acceleration.
Il est également connu d'associer au premier échangeur de chaleur servant au refroidissement du moteur un second échangeur de chaleur de forme générale plate servant au refroidissement de l'air de suralimentation du moteur, ou plus précisément de l'air sortant du turbocompresseur utilisé pour l'air de suralimentation, les premier et second échan- geurs de chaleur étant orientés parallèlement à un même plan sensiblement vertical et juxtaposés de façon à être traversés en série par un courant d'air dirigé perpendiculairement à ce plan. En raison de la température élevée de l'air sortant du turbocompresseur, les boîtes à fluide du second échangeur de chaleur sont généralement en métal, notamment en alliage d'aluminium.It is also known to associate with the first heat exchanger used for cooling the engine a second generally flat heat exchanger used for cooling the charge air of the engine, or more precisely the air leaving the turbocharger used for the charge air, the first and second heat exchangers being oriented parallel to the same substantially vertical plane and juxtaposed so as to be traversed in series by a stream of air directed perpendicular to this plane. Due to the high temperature of the air leaving the turbocharger, the fluid boxes of the second heat exchanger are generally made of metal, in particular of aluminum alloy.
Le but de l'invention est de tirer parti de ces éléments métalliques du second échangeur de chaleur pour assurer la fixation du vase d'expansion.The object of the invention is to take advantage of these metal elements of the second heat exchanger to secure the expansion tank.
L'invention vise notamment un ensemble du genre défini en introduction, et prévoit qu'il comprend un second échangeur de chaleur de forme générale plate, les premier et second échangeurs de chaleur étant orientés parallèlement à un même plan sensiblement vertical et juxtaposés de façon à être traversés en série par un courant d'air dirigé perpendiculairement à ce plan, et que le vase d'expansion est fixé de façon rigide sur au moins un élément du second échangeur de chaleur.The invention relates in particular to an assembly of the kind defined in the introduction, and provides that it comprises a second heat exchanger of generally flat shape, the first and second heat exchangers being oriented parallel to the same substantially vertical plane and juxtaposed so as to be crossed in series by an air flow directed perpendicular to this plane, and the expansion tank is rigidly fixed to at least one element of the second heat exchanger.

L'ensemble illustré comprend un radiateur 1 de refroidissement du moteur thermique d'entraînement d'un véhicule automobile et un radiateur 2 de refroidissement d'air de suralimentation de ce moteur. Le radiateur 1 a une forme générale plate rectangulaire et s'étend sensiblement selon un plan vertical perpendiculaire à l'axe longitudinal du véhicule. Il comprend deux boîtes à fluide en matière plastique 3 et 4 s'étendant horizontalement, le long des côtés supérieur et inférieur respectivement du radiateur et munis de raccords 5 et 6 dont l'un sert à l'entrée et l'autre à la sortie du fluide de refroidissement. Les boîtes à fluide 3 et 4 sont reliées l'une à l'autre par des tubes de circulation de fluide verticaux. Le radiateur 2 a également une forme générale plate et s'étend selon un plan parallèle à celui du radiateur 1, en étant sensiblement accolé à la face de celui-ci tournée vers l'avant du véhicule. Le radiateur 2 comporte deux boîtes à fluide 7 et 8 moulées en alliage d'aluminium, allongées dans la direction verticale et s'étendant respectivement le long des côtés gauche et droit du radiateur 1. De façon connue en soi, les boîtes à fluide 7 et 8 sont reliées entre elles par les tubes horizontaux pour la circulation de l'air à refroidir. La région supérieure 9, 10 de chacune d'elles forme une tubulure d'entrée ou de sortie de l'air qui est recourbée vers l'arrière et contourne le radiateur 1 au niveau des extrémités de sa boîte à fluide supérieure 3, pour être reliée au compresseur d'air de suralimentation et au collecteur d'admission non représentés, situés en arrière de l'ensemble de radiateurs.The illustrated assembly includes a
La boîte à fluide 3 est en liaison de communication de fluide avec un vase d'expansion 11 de forme cylindrique de révolution dont l'axe est parallèle à la direction longitudinale de cette même boîte à fluide. Le vase d'expansion 11 est réalisé en laiton. Sa longueur est inférieure à la largeur de l'espace disponible entre les tubulures 9 et 10, en avant du radiateur 1. Il est donc disposé pour partie dans cet espace libre, et en partie en avant par rapport à la face avant du radiateur 2. Il s'étend par ailleurs, dans la direction verticale, pour partie en regard de la boîte à fluide supérieure 3 du radiateur 1, pour partie au-dessus et pour partie au-dessous de celle-ci. Le vase d'expansion 11 est fixé sur deux paires de pattes venues de moulage avec les tubulures 9 et 10 respectivement et disposées symétriquement par rapport au plan vertical médian du véhicule. Chaque paire comprend une patte inférieure 12 et une patte supérieure 13. La patte inférieure 12 s'étend horizontalement vers l'avant et vers le plan médian à partir de la tubulure 9 ou 10. Le vase d'expansion repose sur sa face supérieure par l'intermédiaire d'une pièce de jonction 14 qui est soudée sur la face externe de la paroi cylindrique du vase d'expansion et fait saillie au-delà de l'extrémité de celui-ci, où elle est reliée à la patte 12 par un boulon 15 à proximité du plan axial vertical 16 du vase d'expansion. La patte supérieure 13 s'étend à partir de la région supérieure horizontale de la tubulure 9 ou 10 en direction du plan longitudinal médian du véhicule, selon un plan légèrement incliné par rapport à la verticale. A cette patte supérieure est également reliée par un boulon 17 une pièce de jonction 18 soudée sur la face extérieure de la paroi cylindrique du vase d'expansion, la pièce 18 s'éloignant suffisamment de cette paroi pour permettre le logement du boulon. Celui-ci est contenu dans le dièdre droit délimité par les demi-plans s'étendant respectivement vers l'arrière et vers le haut à partir de l'axe longitudinal du vase d'expansion.The
De manière préférentielle, il peut être prévu que le vase d'expansion soit fixé d'une manière rigide au niveau de l'une 8 des boîtes à fluide et d'une manière libre en coulissement, selon la direction du faisceau de tubes, à l'autre 7 des boîtes à fluide de manière à autoriser sans entrave la dilatation du faisceau de tubes.Preferably, provision may be made for the expansion vessel to be rigidly fixed at one of the fluid boxes and to slide freely, in the direction of the tube bundle, at the other 7 of the fluid boxes so as to allow unhindered expansion of the tube bundle.
En pratique, cela peut se faire en prévoyant un boulon 17, au niveau de la boîte à fluide 7, qui soit épaulé et cela au niveau de la liaison de la patte 13 et de la pièce de jonction 18.In practice, this can be done by providing a
