Selon l'invention, la structure pour accélérer la vitesse de réactivité de la zéolithe dans des dispositifs de refroidissement et/ou de chauffage contenant de la zéolithe en granulés ou en billes est caractérisée en ce qu'elle est constituée d'une pièce métallique creuse dont la surface externe est façonnée selon une configuration régulière de façon à présenter une pluralité de saillies. Ainsi, le temps de réactivité est de l'ordre de la minute.According to the invention, the structure for accelerating the speed of reactivity of the zeolite in cooling and / or heating devices containing zeolite in granules or in balls is characterized in that it consists of a hollow metallic piece whose external surface is shaped in a regular configuration of so as to present a plurality of projections. Thus, the reactivity time is of the order of a minute.
De façon avantageuse, la configuration est constituée par des saillies rangées horizontalement et verticalement, dans deux plans, chacune des saillies étant séparée par un petit et un grand espaces de formes parallélépipédiques tels que la largeur de l'aire de la face supérieure et celle de l'aire de la face inférieure du petit espace, entre deux saillies, est de l'ordre de 2 mm, et leurs longueur de l'ordre de 3 mm, et que la largeur de l'aire de la face inférieure et celle de l'aire de la face supérieure du grand espace, entre deux saillies, est comprise entre 4 et 5 mm, et leurs longueurs du même ordre.Advantageously, the configuration consists of projections arranged horizontally and vertically, in two planes, each of the projections being separated by a small and a large space of parallelepipedal shapes such as the width of the area of the upper face and that of the area of the underside of the small space, between two projections, is of the order of 2 mm, and their lengths of the order of 3 mm, and that the width of the area of the underside and that of the area of the upper face of the large space, between two projections, is between 4 and 5 mm, and their lengths of the same order.

Selon un autre mode de réalisation de l'invention, pour une bonne application de la zéolithe sur la structure, on introduit ladite structure dans un tube en verre autour duquel est disposé un dispositif permettant d'induire des courants dits de Foucault dans la structure métallique. Cette réalisation de l'invention est particulièrement appropriée pour être appliquée au réfrigérateur ménager du fait de sa conception technique très simple et de son faible coût de fabrication.According to another embodiment of the invention, for a good application of the zeolite on the structure, said structure is introduced into a glass tube around which is arranged a device making it possible to induce so-called eddy currents in the metal structure . This embodiment of the invention is particularly suitable for being applied to a household refrigerator because of its very simple technical design and its low manufacturing cost.

- sintering of the zeolite deposit on the structure, carried out in an oven at a temperature of 350 ° C.
Les autres caractéristiques et avantages de l'invention résulteront de la description suivante, en se rapportant aux dessins annexés dans lesquels :Other features and advantages of the invention Will result from the following description, referring to the accompanying drawings in which:
La figure 1 est une représentation schématique, vue de dessus, d'une partie de ladite structure.Figure 1 is a schematic representation, seen from above, of a part of said structure.
La figure 1a est une vue en coupe d'une partie de la structure selon l'axe I-I′ de la figure 1.FIG. 1a is a sectional view of part of the structure along the axis I-I ′ of FIG. 1.
La figure 1b est une vue en coupe d'une partie de la structure selon l'axe II-II′ de la figure 1.FIG. 1b is a sectional view of part of the structure along the axis II-II ′ of FIG. 1.
La figure 2 est une vue schématique en coupe selon I-I′ d'une forme d'exécution non limitative de la structure selon l'invention.Figure 2 is a schematic sectional view along I-I 'of a non-limiting embodiment of the structure according to the invention.
Selon la figure 1, la structure est constituée d'une pièce métallique 1 dans laquelle a été creusé un canal 4 et sur laquelle ont été façonnées des séries de saillies 5 disposées plus ou moins régulièrement selon un même plan longitudinal et un même plan transversal à l'axe du canal 4.According to FIG. 1, the structure consists of a metal part 1 in which a
L'adsorbant, ici de la zéolithe 6, adhère aux parois des saillies 5 adjacentes aux espaces 2. La zéolithe 6 présente un diamètre de l'ordre de 3 mm et se présente sous forme granulaire.The adsorbent, here zeolite 6, adheres to the walls of the
Avant introduction de la zéolithe 6 dans les volumes 2, on dispose dans les espaces 3 des lamelles plastiques non représentées sur les figures.Before introduction of the zeolite 6 into the
Selon la figure 2, on a représenté une application de la structure. La structure est placée dans un tube de verre 7 autour duquel est disposé un inducteur de moyenne fréquence 8 par exemple. La structure est constituée en fait de deux structures simples juxtaposées comportant des saillies 5 uniquement sur un de leurs côtés et présente par conséquent une configuration telle que les deux canaux 4 sont adjacents. Par un des deux canaux 4a on introduit le liquide ou gaz chaud ou froid par l'intermédiaire de la canalisation 11, puis il est évacué, via la liaison tubulaire 9, dans le second canal 4b, et rejeté enfin à l'extérieur par la canalisation 10.According to Figure 2, there is shown an application of the structure. The structure is placed in a
La mise en oeuvre du procédé de dépôt de la zéolithe 6 est réalisée de la manière suivante :The zeolite 6 deposition process is carried out as follows:
On comble les espaces 3 par des lamelles plastiques précitées. On introduit ensuite la zéolithe 6 dans les espaces 2. Puis on place la structure dans un bain contenant une solution telle que celle utilisée dans le FR-A-2 443 485. Une fois le dépôt de zéolithe réalisé sur les faces de saillies 5, on retire la structure du bain et on ôte les lamelles de plastique. On introduit alors la structure dans un four à une température de l'ordre de 300°C pour réaliser le frittage de la zéolithe 6. On obtient alors un dépôt peu épais (0,1 à 0,5 mm) de zéolithe 6 sur deux des faces de chaque saillie 5, dépôt continu car les granulés ou grains de zéolithe sont aussi collés les uns aux autres mais pas complètement : on remarque ainsi des espaces entre deux grains ou granulés, ce qui favorise ainsi le passage du gaz ou liquide pour le refroidissement et/ou le chauffage d'une enceinte. Les espaces 2 sont aussi remplis de zéolithe (voir figures 1a et 1b). Par conséquent, lors de l'utilisation de la structure, l'absence de zéolithe 6 sur les deux autres faces des saillies 5 va favoriser l'accélération de la vitesse de réactivité de la zéolithe 6. Cette vitesse est accélérée car le dépôt de zéolithe 6 effectué uniquement sur les deux faces des saillies 5 présente une très faible épaisseur (entre 0,1 et 0,5 mm) favorisant donc les échanges et accélérant les opérations de refroidissement/chaufffage. En outre, la disposition des billes ou granulés de zéolithe (6) collés en partie seulement les uns aux autres va aussi favoriser les échanges : le liquide ou le gaz passe entre les billes ou les granulés, accélérant ainsi la vitesse de réactivité de la zéolithe 6. Lesdites saillies 5 peuvent être comparées à des puits de chaleur.The
Selon la figure 2, le chauffage de la structure disposée dans un tube de verre est accéléré par l'inducteur de moyenne fréquence 8, favorisant ainsi la vitesse de réactivité de la zéolithe 6.According to FIG. 2, the heating of the structure placed in a glass tube is accelerated by the
Cette structure est particulièrement adaptée pour les dispositifs de chauffage et/ou de refroidissement du type réfrigérateur mais aussi pour la climatisation de véhicules.This structure is particularly suitable for heating and / or cooling devices of the refrigerator type but also for air conditioning of vehicles.
