Abstract

The exchanger consists of a cubic body 1 enclosing plates 1a defining the two circuits, and four demountable tanks 2 to 5 having an opening set into the square profile of the body. Some of these tanks have a filtering wall 9 and others have a motor-driven fan 6. All the tanks have lateral connecting pipes 7, 8, 10, 11 which can be given four different orientations to obtain a suitable arrangement for each tank.

Description

La présente invention a trait aux échangeurs de température à flux croisés, du genre de ceux utilisés dans les systèmes de ventilation mécanique pour locaux afin que pendant les périodes de chauffage l'air vicié extrait de l'habitation cède une partie au moins de ses calories à l'air frais qui y pénètre. The present invention relates to cross-flow temperature exchangers, of the type used in mechanical ventilation systems for premises so that during periods of heating the stale air extracted from the house gives up at least part of its calories. to the fresh air entering it.

On sait que les échangeurs de ce genre comprennent généralement deux circuits distincts orientés perpendiculairement l'un à l'autre, chacun de ceux-ci étant doté d'une paroi de filtrage et d'un moto-ventilateur. La partie centrale est occupée par une série de plaques parallèles, disposées de façon à ce que leurs faces opposées soit léchées par l'air des deux circuits de façon à assurer l'rechange calorique. Bien évidemment chaque circuit est doté d'au moins une buse d'entrée et d'au moins une buse de sortie et celles-ci doivent être raccordées aux canalisations de l'installlation de ventilation mécanique du local considéré. It is known that exchangers of this kind generally comprise two separate circuits oriented perpendicular to each other, each of these being provided with a filtering wall and a motor-fan. The central part is occupied by a series of parallel plates, arranged so that their opposite faces are licked by the air of the two circuits so as to ensure caloric exchange. Obviously each circuit is provided with at least one inlet nozzle and at least one outlet nozzle and these must be connected to the pipes of the mechanical ventilation installation of the room in question.

Ce raccordement pose fréquemment des problèmes assez délicats. This connection frequently poses fairly delicate problems.

Effectivement l'installateur n'est pas libre d'orienter les canalisations comme il l'entend2 de telle sorte qu'il doit procéder à la pose de coudes, interposés entre les extrémités des canalisations et les buses de ltéchangeur. Outre leur prix de revient, ces parties coudées ont ltinconvenient d'engendrer des pertes de charge non négligeables dans la circulation de l'air de l'installation.Indeed, the installer is not free to orient the pipes as he sees fit2 so that he must proceed with the installation of elbows, interposed between the ends of the pipes and the exchanger nozzles. In addition to their cost price, these bent parts have the disadvantage of generating significant pressure losses in the air circulation of the installation.

C'est principalement à cet inconvénient qu'entend remédier la présente invention, laquelle consiste essentiellement à réaliser la partie centrale de l'échangeur sous la forme d'une carcasse cubique-qui n'est fermée que sur deux côtés opposés, et à associer à cette carcasse quatre caissons démontables présentant au moins une face ouverte établie au même profil carré que ladite carcasse, chacun desdits caissons étant pourvu d'au moins une buse pour son raccordement aux canalisations de l'installation considérée. It is mainly this drawback that the present invention intends to remedy, which essentially consists in producing the central part of the exchanger in the form of a cubic carcass which is closed only on two opposite sides, and in associating to this carcass four removable boxes having at least one open face established with the same square profile as said carcass, each of said boxes being provided with at least one nozzle for its connection to the pipes of the installation considered.

On comprend que cette buse de raccordement est susceptible d'affecter quatre orientations distinctes moyennant un simple déplacement angulaire du caisson correspondant par rapport à la carcasse cubique centrale. Les opérations de raccordement sont ainsi considérablement simplifiées au point qu'on peut le plus souvent se dispenser de tout coude intermédiaire. It is understood that this connection nozzle is capable of affecting four distinct orientations by means of a simple angular displacement of the corresponding box relative to the central cubic carcass. The connection operations are thus considerably simplified to the point that one can most often dispense with any intermediate bend.

Conformément à un mode de mise en oeuvre préféré de l'invention, deux des quatre caissons démontables sont équipés d'une paroi filtrante, tandis que chacun des deux autres renferme un moto-ventilateur pour assurer la circulation de l'air dans le circuit correspondant. On notera par ailleurs que la fixation des caissons contre l'enveloppe est avantageusement opérée à l'aide de systemes d'assemblage rapide, tels que circlips, leviers à dépasseient de point mort, etc... In accordance with a preferred embodiment of the invention, two of the four removable boxes are equipped with a filtering wall, while each of the other two contains a motor-fan to ensure the circulation of air in the corresponding circuit . It will also be noted that the fixing of the boxes against the envelope is advantageously carried out using quick assembly systems, such as circlips, levers beyond the neutral point, etc.

te dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer
Fig. 1 est une vue en perspective des éléments constitutifs d'un échangeur suivant l'invention, représenté préalablement à l'assemblage des caissons contre la carcasse centrale.the appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is likely to provide
Fig. 1 is a perspective view of the components of a heat exchanger according to the invention, shown before the assembly of the boxes against the central carcass.

Fig. 2 reproduit fig. 1 après assemblage et orientation des caissons. Fig. 2 reproduced fig. 1 after assembly and orientation of the boxes.

En fig. 1 la référence 1 désigne une carcasse cubique qui n'est fermée que sur deux parois opposées. A l'intérieur de cette carcasse 1 est montée, à la façon en soi connue dans l'industrie des échangeurs de température à flux croisés, une série de plaques la orientées parallèlement les unes aux autres et maintenues à un tres léger espacement réciproque afin de permettre le passage de l'air des deux circuits de l'échangeur. In fig. 1 the reference 1 designates a cubic carcass which is closed only on two opposite walls. Inside this carcass 1 is mounted, in a manner known per se in the industry of cross-flow temperature exchangers, a series of plates 1a oriented parallel to each other and maintained at a very slight reciprocal spacing in order to allow the passage of air from the two exchanger circuits.

A la carcasse 1 sont associés quatre caissons démontables, référencés 2, 3, 4 et 5. Chacun de ces caissons se présente sous la forme d'un parallélipipède rectangle qui n'est ouvert que sur un seul côté et dont les deux grandes faces comportent une section carrée identique à celle de l'un des côtés de la carcasse 1, de façon à ce que lesdits caissons soient susceptibles d'être appliqués contre un côté ouvert de ladite carcasse en occupant toute la section découverte. With the carcass 1 are associated four removable boxes, referenced 2, 3, 4 and 5. Each of these boxes is in the form of a rectangular parallelepiped which is open only on one side and whose two large faces have a square section identical to that of one of the sides of the carcass 1, so that said boxes are capable of being applied against an open side of said carcass while occupying the entire uncovered section.

A l'intérieur de chacun des deux caissons référencés 2 et 3 est monté un moto-ventilateur 6 dont l'ouie d'aspiration est tournée en direction du côté ouvert du caisson envisagé, tandis que l'ouîe de sortie se raccorde à une buse ou manchette référencée 7 pour le caisson 2, 8 pour le caisson 3. Par contre chacun des deux autres caissons 4 et 5 renferme une paroi filtrante 9, avantageusement orientée obliquement suivant une diagonale du parallélipipède ; le caisson 4 est équipé de deux buses ou manchettes parallèles 10 tandis que le caisson 5 n'en comporte qu'une seule, référencée 11. Inside each of the two boxes referenced 2 and 3 is mounted a motor-fan 6, the suction port of which is turned towards the open side of the box envisaged, while the outlet port is connected to a nozzle or sleeve referenced 7 for the box 2, 8 for the box 3. On the other hand, each of the other two boxes 4 and 5 contains a filtering wall 9, advantageously oriented obliquely along a diagonal of the parallelepiped; the box 4 is equipped with two parallel nozzles or sleeves 10 while the box 5 has only one, referenced 11.

La fixation amovible des caissons contre la carcasse 1 est assurée à l'aide de tout systeme d'assemblage rapide connu en pratique ; dans l'exemple de réalisation considéré l'on a supposé qu'on avait recours à cet effet à des brides ou circlips démontables réunissant des crochets 12 respectivement prévus par paires sur le pourtour du ôté ouvert de chaque caisson et sur chacune des deux faces fermées de la carcasse 1. The removable fixing of the boxes against the carcass 1 is ensured using any quick assembly system known in practice; in the embodiment considered, it was assumed that recourse was made to this effect with removable flanges or circlips bringing together hooks 12 respectively provided in pairs around the periphery of the open side of each box and on each of the two closed faces carcass 1.

L'étanchéité du montage est assurée à l'aide de joints ou garnitures (non représentés) qui se trouvent comprimes entre la carcasse et les caissons une fois ces derniers assemblés.The assembly is sealed using seals or fittings (not shown) which are compressed between the carcass and the boxes once the latter are assembled.

Fig. 2 montre l'ensemble obtenu après assemblage des cinq pièces constitutives à l'aide des brides 12' associées aux crochets 12. On réalise de la sorte deux circuits distincts orientés en croix ; le moto-ventilateur incorporé au caisson 2 aspire, à travers les deux buses 10 du caisson 4; l'air vicié du local (fleches noires) qui est purifié par la paroi filtrante 9 et qui avant d'être refoulé à l'extérieur par la buse 7 du caisson 2, cède ses calories à l'air frais (flèches blanches) lors de son passage à travers la carcasse centrale 1. Cet air frais est aspiré par le moto-ventilateur du caisson 2, l'aspiration s'effectuant à travers la buse 11 et le refoulement par la buse 8. Fig. 2 shows the assembly obtained after assembly of the five constituent parts using the flanges 12 ′ associated with the hooks 12. Two separate circuits are thus oriented in the form of a cross; the motor-fan incorporated in the box 2 sucks, through the two nozzles 10 of the box 4; the stale air in the room (black arrows) which is purified by the filtering wall 9 and which before being discharged outside by the nozzle 7 of the box 2, gives up its calories to the fresh air (white arrows) during from its passage through the central carcass 1. This fresh air is sucked in by the motor-fan of the box 2, the suction being carried out through the nozzle 11 and the discharge by the nozzle 8.

On comprend que les buses 7, 8, 10 et 11 sont susceptibles d'entre disposées suivant quatre orientations différentes moyennant déplacement angulaire des caissons par rapport à la carcasse 1 préalablement à la mise en place des brides d'assemblage 12 ; cette faculté d'orientation simplifie le raccordement de l'échangeur à l'installation de ventilation mécanique, en évitant le plus souvent d'avoir à prévoir des parties coudées aux extrémités des canalisations à relier audit échangeur. Cette simplification se répercute évidemment de manière favorable au niveaù du prix de revient et de la puissance de l'installation (suppression des pertes de charge dues aux parties coudées). It is understood that the nozzles 7, 8, 10 and 11 are capable of being arranged in four different orientations by angular displacement of the boxes relative to the carcass 1 prior to the installation of the assembly flanges 12; this faculty of orientation simplifies the connection of the exchanger to the mechanical ventilation installation, most often avoiding having to provide bent portions at the ends of the pipes to be connected to said exchanger. This simplification obviously has a favorable effect on the level of the cost price and the power of the installation (elimination of pressure losses due to the bent parts).

Il va de soi que les caissons sont susceptibles de comporter un nombre quelconque de buses de raccordement, en fonction des principaux types d'installations. It goes without saying that the boxes are likely to include any number of connection nozzles, depending on the main types of installation.

Il doit d'ailleurs être entendu que la description qui précede n'a été donnée qu'à titre d'exemple et qu'elle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalentsO  It should also be understood that the foregoing description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by any other equivalentO
