Abstract

The honeycomb is split into two separate blocks by a central, vertical gap. The warm fluid is fed into the bottom of the heat exchanger by a single pipe (8) and is taken from the top by separate connections (27,28). The single feed pipe is mounted in the gap between the sections. The bottom fluid tank (4) extends the whole width of the two sections. The upper tank (3) is split by a bulkhead (5). For non individual control the two tank is replaced by a single tank, with a single outlet.

Description

La présente invention concerne un échangeur de chaleur pour véhicule, et en particulier pour voiture de tourisme, avec deux blocs de tubes à ailettes pouvant être affectés à deux circuits de chauffage séparés et disposés côte à côte entre une boîte à eau supérieure et une boîte à eau inférieure, un circuit d'aller étant relié à la boîte à eau inférieure et deux circuits de retour à la boîte à eau supérieure, divisée par une cloison située entre les deux blocs de tubes à ailettes. The present invention relates to a heat exchanger for a vehicle, and in particular for a passenger car, with two blocks of finned tubes which can be assigned to two separate heating circuits and placed side by side between an upper water box and a box. lower water, a flow circuit being connected to the lower water box and two return circuits to the upper water box, divided by a partition situated between the two blocks of finned tubes.

Un échangeur de chaleur du type précité est utilisé par exemple sur les voitures de tourisme pour chauffer différemment les deux côtés du véhicule. Les passagers peuvent ainsi régler la quantité de fluide de chauffage circulant dans un ou dans les deux blocs de tubes à ailettes, provenant d'un circuit d'aller commun et réparti dans la boîte à eau inférieure en fonction des ouvertures dégagées au voisinage des circuits de retour dans la boîte à eau supérieure. A heat exchanger of the aforementioned type is used for example on passenger cars to heat the two sides of the vehicle differently. Passengers can thus adjust the quantity of heating fluid circulating in one or in the two blocks of finned tubes, coming from a common flow circuit and distributed in the lower water box according to the openings cleared in the vicinity of the circuits. back in the upper water box.

L'invention vise à réaliser un échangeur de chaleur du type précité, de facon à permettre son montage même dans un espace limité. The invention aims to produce a heat exchanger of the aforementioned type, so as to allow its mounting even in a limited space.

Selon une caractéristique essentielle de l'invention, la boîte à eau inférieure comporte entre les deux blocs de tubes à ailettes un raccord pour une canalisation d'aller. According to an essential characteristic of the invention, the lower water box comprises between the two blocks of finned tubes a connector for a flow pipe.

La canalisation d'aller est ainsi intégrée dans l'échangeur de chaleur et n'exige donc pratiquement aucun espace supplémentaire. La séparation des ailettes appartenant aux deux blocs de tubes à ailettes assure en outre la séparation thermique de ces blocs, de sorte qu'une influence mutuelle est pratiquement exclue. La canalisation d'aller est reliée directement à la boîte à eau inférieure. La boîte à eau supérieure ne comporte ainsi que les raccords des canalisations de retour. Une modification simple, à savoir un couvercle modifié pour la boîte à eau supérieure, permet ainsi d'utiliser le même échangeur de chaleur quand une régulation séparée des deux blocs de tubes à ailettes n'est pas souhaitée. Dans ce cas, seul le couvercle de la boîte à eau supérieure est remplacé par un autre qui ne comporte pas de cloison et qu'un seul raccord pour une canalisation de retour. The flow line is thus integrated into the heat exchanger and therefore requires practically no additional space. The separation of the fins belonging to the two blocks of fin tubes further ensures the thermal separation of these blocks, so that mutual influence is practically excluded. The supply line is connected directly to the lower water box. The upper water box thus only includes the connections of the return pipes. A simple modification, namely a modified cover for the upper water box, thus makes it possible to use the same heat exchanger when separate regulation of the two blocks of finned tubes is not desired. In this case, only the cover of the upper water box is replaced by another which does not have a partition and only one connection for a return pipe.

D'autres caractéristiques et avantages de l'invention seront mieux compris à l'aide de la description détaillée ci-dessous d'exem ples de réalisation et du dessin annexé sur lequel la figure 1 est une élévation d'un échangeur de chaleur, vu du côté sortie de l'air et dans lequel une canalisation d'aller est reliée directement à la boîte à eau inférieure; la figure 2 est une coupe verticale suivant l'axe II-II de l'échan- geur de chaleur selon figure 1; et la figure 3 est une coupe horizontale suivant l'axe III-III de la figure 2. Other characteristics and advantages of the invention will be better understood with the aid of the detailed description below of exemplary embodiments and of the appended drawing in which FIG. 1 is an elevation of a heat exchanger, seen on the air outlet side and in which a flow pipe is connected directly to the lower water box; Figure 2 is a vertical section along the axis II-II of the heat exchanger according to Figure 1; and FIG. 3 is a horizontal section along the axis III-III of FIG. 2.

L'échangeur de chaleur représenté aux figures 1 et 2 est un élément chauffant destiné au chauffage ou à une installation de climatisation d'une voiture. Il comporte deux blocs de tubes à ailettes 1 et 2, constitués chacun par de nombreux'tubes ronds 13 parallèles et sur lesquels sont fixées perpendiculairement de fines ailettes 6 en tôle. Les extrémités des tubes 13 disposés verticalement débouchent dans une boîte à eau supérieure 3 et une bolte à eau inférieure 4. The heat exchanger shown in Figures 1 and 2 is a heating element for heating or an air conditioning installation of a car. It comprises two blocks of finned tubes 1 and 2, each constituted by numerous round tubes 13 parallel and on which thin sheet metal fins 6 are fixed perpendicularly. The ends of the tubes 13 arranged vertically open into an upper water box 3 and a lower water bowl 4.

La boîte à eau supérieure 3 est constituée par une plaque tubulaire 24 et un couvercle 25, reliés par un collet battu circulaire avec interposition d'un joint d'étanchéité 26. Les extrémités supérieures des tubes ronds 13 sont fixées avec étanchéité sur la plaque tubulaire 24, en particulier par dudgeonnage. La bote à eau supérieure 3 est divisée par une cloison 5, disposée au milieu des deux blocs 1 et 2, réalisée en une seule pièce avec le couvercle 25 et prenant appui sur le profilé d'étanchéité 26. La cloison 5 divise la boîte à eau supérieure 3 en deux chambres, munie chacune d'un raccord 27 ou 28 auquel est reliée une canalisation de retour.The upper water box 3 is constituted by a tubular plate 24 and a cover 25, connected by a circular beaten collar with interposition of a seal 26. The upper ends of the round tubes 13 are fixed with sealing on the tubular plate 24, in particular by expansion. The upper water box 3 is divided by a partition 5, arranged in the middle of the two blocks 1 and 2, produced in a single piece with the cover 25 and bearing on the sealing profile 26. The partition 5 divides the box upper water 3 in two chambers, each provided with a connector 27 or 28 to which a return pipe is connected.

La boîte à eau inférieure 4 comporte un couvercle 21 monobloc, sur lequel deux plaques tubulaires 22 et 23 séparées pour chacun des blocs de tubes à ailettes 1 et 2 sont fixées chacune par un collet battu circulaire. Les extrémités des tubes 13 sont fixées avec étan chéité sur ces plaques tubulaires 22 et 23, de préférence par dudgeonnage. Entre les deux plaques tubulaires 22, 23 et les deux collets battus circulaires, présentant la forme d'un rectangle, un ligament transversal est formé sur le couvercle 21 avec un raccord 20, en saillie entre les deux blocs de tubes à ailettes 1 et 2. Le raccord 20 est constitué par une saillie tubulaire 29, qui forme une bride 30 perpendiculaire au couvercle 21. La bride 32 d'un tube 33 d'aller est fixée par des vis 34 sur cette bride 30, avec interposition d'un joint torique 31.Le tube 8 constituant la canalisation d'aller est disposé parallèlement aux tubes 13 des blocs de tubes à ailettes 1 et 2, et entre ces derniers, jusqu'au voisinage immédiat de la boîte à eau supérieure 3, puis replié de façon à être en saillie sur le côté de sortie de l'air de l'échangeur de chaleur. The lower water box 4 has a one-piece cover 21, on which two tubular plates 22 and 23 separated for each of the blocks of finned tubes 1 and 2 are each fixed by a circular beat collar. The ends of the tubes 13 are fixed tightly to these tubular plates 22 and 23, preferably by expansion. Between the two tubular plates 22, 23 and the two circular beaten collars, having the shape of a rectangle, a transverse ligament is formed on the cover 21 with a connector 20, projecting between the two blocks of finned tubes 1 and 2 The connector 20 consists of a tubular projection 29, which forms a flange 30 perpendicular to the cover 21. The flange 32 of a tube 33 to go is fixed by screws 34 on this flange 30, with the interposition of a seal. The tube 8 constituting the outgoing pipe is arranged parallel to the tubes 13 of the blocks of finned tubes 1 and 2, and between the latter, up to the immediate vicinity of the upper water box 3, then folded so to project from the air outlet side of the heat exchanger.

Le fluide de chauffage dirigé par la canalisation d'aller 8 dans la boîte à eau inférieure 4, et en particulier l'eau de refroidissement d'un véhicule, se répartit dans ladite boîte 4 entre les deux blocs de tubes à ailettes 1 et 2. Des vannes de réglage sont affectées aux raccords 27 et 28 des canalisations de retour et permettent d'ajuster le volume de retour, c'est-à-dire le volume de fluide de chauffage circulant alors dans un des blocs de tubes à ailettes 1 et 2, ou dans les deux. Il est ainsi possible de chauffer les blocs 1 et 2 à des températures différentes et de réchauffer l'habitacle du véhicule différemment sur les deux côtés. The heating fluid directed by the supply line 8 in the lower water box 4, and in particular the cooling water of a vehicle, is distributed in said box 4 between the two blocks of finned tubes 1 and 2 Adjustment valves are assigned to the connections 27 and 28 of the return pipes and make it possible to adjust the return volume, that is to say the volume of heating fluid then circulating in one of the blocks of finned tubes 1 and 2, or both. It is thus possible to heat the blocks 1 and 2 to different temperatures and to heat the passenger compartment of the vehicle differently on the two sides.

Afin d'éviter une influence thermique mutuelle des deux blocs de tubes à ailettes 1 et 2, il est prévu d'arrêter les ailettes 6 à une certaine distance de la direction d'aller 8, comme le montrent en particulier les figures 1 et 3. Il est en outre prévu de munir la conduite d'aller, du côté d'entrée de l'air, d'un capot 37 qui recouvre l'espace compris entre les deux blocs de tubes à ailettes 1 et 2, dudit côté. In order to avoid a mutual thermal influence of the two blocks of finned tubes 1 and 2, it is planned to stop the fins 6 at a certain distance from the direction of travel 8, as shown in particular in FIGS. 1 and 3 It is also planned to provide the supply line, on the air inlet side, with a cover 37 which covers the space between the two blocks of finned tubes 1 and 2, on said side.

La forme de réalisation selon les figures 1 à 3 présente l'avantage que l'échangeur de chaleur représenté peut etre facilement modifié aussi pour un fonctionnement automatique, sans réglage différent de la température dans les blocs de tubes à ailettes 1 et 2. The embodiment according to FIGS. 1 to 3 has the advantage that the heat exchanger shown can be easily modified also for automatic operation, without different adjustment of the temperature in the blocks of finned tubes 1 and 2.

La bolte à eau supérieure 3 est alors simplement munie d'un couvercle modifié, qui diffère du couvercle 25 représenté par la suppression de la cloison 5 et le remplacement des deux raccords 27 et 28 par un seul raccord central pour le retour.The upper water bowl 3 is then simply provided with a modified cover, which differs from the cover 25 represented by the removal of the partition 5 and the replacement of the two connections 27 and 28 by a single central connection for the return.

Bien entendu, diverses modifications peuvent etre apportées par l'homme de l'art au principe et aux dispositifs qui viennent d'etre décrits uniquement à titre d'exemples non limitatifs, sans sortir du cadre de l'invention.  Of course, various modifications can be made by those skilled in the art to the principle and to the devices which have just been described only by way of nonlimiting examples, without departing from the scope of the invention.
