Description

La présente invention due aux travaux de monsieur le professeur Félix TROMBE et de messieurs, Raymond BERGER, Maurice de CACHARD et André GOUZY du Commissariat à l'Energie Atomique, a pour objet un appareil modulaire de production de froid.The present invention due to the work of Professor Félix TROMBE and gentlemen, Raymond BERGER, Maurice de CACHARD and André GOUZY from the French Atomic Energy Commission, has for its object a modular device for producing cold.

On connaît selon l'art antérieur des appareils pour la production de froid fonctionnant de manière autonome, c'est-à-dire sans approvisionnement extérieur en énergie et ne comportant aucune pièce mobile, ce qui leur confère une grande simplicité et une excellente fiabilité. Ces appareils sont basés sur la propriété connue que présente l'atmosphère terrestre de laisser passer préférentiellement le rayonnement compris entre 8 et 131i et entre 16 et 25µ. Une partie des rayonnements émis par les corps noirs se situe dans ces plages.Apparatuses for the production of cold operating independently are known according to the prior art, that is to say without external energy supply and having no moving part, which gives them great simplicity and excellent reliability. These devices are based on the known property that the Earth's atmosphere has of preferentially passing the radiation between 8 and 13 1 i and between 16 and 25µ. Part of the radiation emitted by black bodies is in these ranges.

On sait qu'un corps noir est un corps qui absorbe complètement le rayonnement qu'il reçoit, quelle que soit sa longueur d'onde. Un tel corps est en équilibre thermodynamique avec le rayonnement qu'il reçoit et avec le rayonnement qu'il émet. En principe, l'émissivité d'un corps noir est égale à l'unité et s'étend dans tout le spectre, en particulier dans les fenêtres de transparence de l'atmosphère. Lorsqu'un corps noir est placé dans l'atmosphère, la partie d'énergie qu'il rayonne dans lesdites fenêtres est transmise vers l'espace quasiment sans accumulation. Il en résulte un refroidissement du corps émetteur. La chute de température subie par ce corps est toutefois limitée si des échanges thermiques parasites ont lieu avec l'air ambiant ou avec le sol, soit par convection, soit par l'intermédiaire de phénomènes de condensation liés au degré d'humidité de l'air.We know that a black body is a body which completely absorbs the radiation it receives, whatever its wavelength. Such a body is in thermodynamic equilibrium with the radiation it receives and with the radiation it emits. In principle, the emissivity of a black body is equal to unity and extends across the spectrum, in particular in the windows of transparency of the atmosphere. When a black body is placed in the atmosphere, the part of energy that it radiates in said windows is transmitted to space almost without accumulation. This results in cooling of the emitter body. The drop in temperature undergone by this body is however limited if parasitic heat exchanges take place with the ambient air or with the ground, either by convection, or by the intermediary of condensation phenomena linked to the degree of humidity of the air.

Dans les appareils pour la production de froid de type connu, le corps qui subit un refroidissement du fait de son rayonnement à travers les fenêtres de transparence de l'atmosphère est thermiquement relié à un matériau qui présente une transition solide-liquide au voisinage de la température de fonctionnement de l'appareil. Cette liaison thermique s'effectue au moyen d'un tube de chaleur caloduc qui joue le rôle d'une diode thermique et qui assure la liaison thermique uniquement dans le sens du matériau vers le corps noir. Il en résulte un abaissement de la température du matériau provoquant sa solidification sans que la transformation inverse de la phase solide à la phase liquide puisse se produire, car le transfert des calories qui pourraient provenir du corps rayonnant est bloqué par la diode thermique. L'appareil produit donc du froid et l'emmagasine.In apparatuses for producing cold of known type, the body which undergoes cooling due to its radiation through the windows. very transparent atmosphere is thermally connected to a material which has a solid-liquid transition in the vicinity of the operating temperature of the device. This thermal connection is effected by means of a heat pipe heat pipe which acts as a thermal diode and which ensures thermal connection only in the direction of the material towards the black body. This results in a lowering of the temperature of the material causing it to solidify without the reverse transformation from the solid phase to the liquid phase being able to occur, since the transfer of the calories which could come from the radiating body is blocked by the thermal diode. The device therefore produces cold and stores it.

On a représenté sur la figure 1, un exemple de réalisation d'un tel appareil pour la production de froid de type connu. Cet appareil comporte une surface rayonnante 2 reliée thermiquement à un caloduc 4 constituant une diode thermique. La partie inférieure 6 de ce caloduc est munie d'ailettes 8 qui ont pour but d'accroître la surface d'échange entre le matériau fusible et le caloduc 4, et est immergée à l'intérieur d'un matériau fusible qui est liquide à la température ambiante diurne, de l'eau par exemple, ce réservoir étant isolé thermiquement du sol et rendu étanche par ses parois par exemple en matière plastique. Ce réservoir de stockage n'a pas été représenté sur la figure 1.There is shown in Figure 1, an embodiment of such an apparatus for producing cold of known type. This device comprises a radiating surface 2 thermally connected to a heat pipe 4 constituting a thermal diode. The lower part 6 of this heat pipe is provided with fins 8 which have the purpose of increasing the exchange surface between the fusible material and the heat pipe 4, and is immersed inside a fusible material which is liquid at the daytime ambient temperature, of water for example, this tank being thermally insulated from the ground and sealed by its walls, for example made of plastic. This storage tank has not been shown in FIG. 1.

A sa partie supérieure, le caloduc 4 présente une structure capillaire discontinue, ce qui permet de réaliser la fonction de diode thermique : lorsque la surface rayonnante est à une température supérieure à celle de l'enceinte de stockage, le liquide condensé du caloduc reste dans la partie basse du caloduc et le transfert de calories par le caloduc ne peut s'effectuer.At its upper part, the heat pipe 4 has a discontinuous capillary structure, which makes it possible to perform the function of thermal diode: when the radiating surface is at a temperature higher than that of the storage enclosure, the condensed liquid of the heat pipe remains in the lower part of the heat pipe and the transfer of calories by the heat pipe cannot be carried out.

Le caloduc est rempli d'un composé dont le point d'évaporation est compatible avec la température de fonctionnement de l'appareil : par exemple, un fréon ou de l'ammoniac.The heat pipe is filled with a compound whose evaporation point is compatible with the operating temperature of the device: for example, a freon or ammonia.

Cependant, les appareils pour la production de froid qui viennent d'être décrits présentent un certain nombre d'inconvénients.However, the apparatuses for producing cold which have just been described have a certain number of drawbacks.

La réalisation du ou des caloducs assurant la liaison thermique entre le stockage froid et la surface rayonnante est complexe, ce qui entraîne un coût de fabrication élevé.The production of the heat pipe (s) ensuring the thermal connection between the cold storage and the radiating surface is complex, which results in a high manufacturing cost.

Les ailettes travaillent en régime de conduction thermique. Par suite, leur rendement n'est pas très élevé. Ainsi, la liaison thermique entre le matériau de stockage et le caloduc 4 est relativement' médiocre.The fins work in thermal conduction regime. As a result, their yield is not very high. Thus, the thermal bond between the storage material and the heat pipe 4 is relatively 'poor.

D'autre part, la surface rayonnante 2 travaille également en régime de conduction thermique. Par suite, la liaison thermique entre cette surface rayonnante et le caloduc est aussi relativement médiocre.On the other hand, the radiating surface 2 also works in thermal conduction regime. As a result, the thermal bond between this radiating surface and the heat pipe is also relatively poor.

Enfin, de tels appareils présentent un encombrement important, analogue à celui d'un parapluie ouvert. Par suite, ils se prêtent mal au transport. Lorsqu'il est nécessaire de transporter un grand nombre de ces appareils sur de longues distances, le coût de ce transport est très élevé.Finally, such devices have a large footprint, similar to that of an open umbrella. As a result, they do not lend themselves well to transport. When it is necessary to transport a large number of these devices over long distances, the cost of this transport is very high.

La présente invention a précisément pour objet un appareil pour la production de froid qui remédie aux inconvénients des dispositifs antérieurement connus. Elle en simplifie la réalisation, en accroît sensiblement le rendement thermique, et surtout elle en diminue l'encombrement au cours du transport, ce qui permet d'obtenir une réduction importante des coûts de fabrication, de transport et d'installation.The present invention specifically relates to an apparatus for producing cold which overcomes the drawbacks of previously known devices. It simplifies the production thereof, appreciably increases its thermal efficiency, and above all it reduces its size during transport, which makes it possible to obtain a significant reduction in the costs of manufacture, transport and installation.

Plus précisément, l'appareil pour la production de froid selon l'invention se caractérise en ce qu'il comprend :

  • - une enceinte de stockage de froid remplie d'un matériau présentant une transmission solide-liquide au voisinage de la température de fonctionnement de l'appareil,
  • - un premier panneau formant une surface rayonnante dont le rayonnement tombe dans au moins une des fenêtres de transparence de l'atmosphère,
  • - un second panneau sensiblement vertical immergé dans le matériau de l'enceinte de stockage de froid,
  • - un conduit formé en serpentin sur chacun des premier et second panneaux, ces conduits étant reliés par des raccords plastiquement déformables pour former un circuit fermé,
  • - une certaine quantité d'un fluide vaporisable dans les conditions de fonctionnement de l'appareil à l'intérieur du circuit fermé, l'ensemble constitué par les premier et second panneaux, le circuit fermé et le fluide caloporteur formant un dispositif de type caloduc jouant le rôle d'une diode thermique qui ne transmet la chaleur que dans le sens de l'enceinte de stockage vers la surface rayonnante.
More specifically, the apparatus for producing cold according to the invention is characterized in that it comprises:
  • - a cold storage enclosure filled with a material having a solid-liquid transmission in the vicinity of the operating temperature of the device,
  • a first panel forming a radiating surface, the radiation of which falls into at least one of the windows for transparency of the atmosphere,
  • - a second substantially vertical panel immersed in the material of the cold storage enclosure,
  • a conduit formed as a serpentine on each of the first and second panels, these conduits being connected by plastically deformable connectors to form a closed circuit,
  • - a certain quantity of a fluid vaporizable under the operating conditions of the device inside the closed circuit, the assembly consisting of the first and second panels, the closed circuit and the heat transfer fluid forming a device of the heat pipe type playing the role of a thermal diode which transmits heat only in the direction of the storage enclosure towards the radiating surface.

De préférence, les raccords entre les conduits en forme de serpentins formés sur chacun des panneaux, l'un pour le départ de la vapeur vers le condenseur, l'autre pour le retour du liquide vers l'évaporateur, sont réalisés en métal recuit, en cuivre ou en aluminium par exemple. Ceci permet de ployer et de déployer l'ensemble un certain nombre de fois sans risque de fuites ou de ruptures.Preferably, the connections between the serpentine-shaped conduits formed on each of the panels, one for the flow of steam to the condenser, the other for the return of the liquid to the evaporator, are made of annealed metal, copper or aluminum for example. This makes it possible to fold and deploy the assembly a certain number of times without risk of leaks or ruptures.

Selon un mode préférentiel de réalisation, l'ensemble constitué par la surface rayonnante, le second panneau formant évaporateur, le circuit fermé, est formé par un seul panneau ajouré dans sa partie centrale pour déterminer un panneau supérieur formant la surface rayonnante et un panneau inférieur formant évaporateur.According to a preferred embodiment, the assembly constituted by the radiating surface, the second evaporator panel, the closed circuit, is formed by a single perforated panel in its central part to determine an upper panel forming the radiating surface and a lower panel forming an evaporator.

D'autres caractéristiques et avantages de l'invention ressortiront mieux à la lecture de la description qui suit, donnée à titre illustratif et nullement limitatif, en référence aux dessins annexés, sur lesquels :

  • - les figures 2 et 3 représentent deux variantes de réalisation de l'appareil de production de froid selon l'invention,
  • - la figure 4 représente un appareil de production de froid selon l'invention, muni d'un flotteur.
Other characteristics and advantages of the invention will emerge more clearly on reading the description which follows, given by way of illustration and in no way limiting, with reference to the appended drawings, in which:
  • FIGS. 2 and 3 represent two alternative embodiments of the cold production apparatus according to the invention,
  • - Figure 4 shows a cold production device according to the invention, provided with a float.

On a représenté sur la figure 2 un premier mode de réalisation de l'appareil de production de froid selon l'invention. Cet appareil se composée d'un premier panneau 10 formant une surface rayonnante dont le rayonnement tombe dans au moins une fenêtre de transparence de l'atmosphère, un second panneau 12 immergé sensiblement verticalement dans le matériau de l'enceinte de stockage. Un conduit 14 en forme de serpentin est formé sur le panneau 10. Un conduit 16 sensiblement identique au conduit 14 est formé sur le panneau 12. L'extrémité 14a du conduit 14 est raccordée à l'extrémité 16a du conduit 16 par un raccord 18. De la même manière, l'extrémité 14b du conduit 14 est raccordée à l'extrémité 16b du conduit 16 par un raccord 20. Le raccord 20 comporte un embout de remplissage 22 par lequel on introduit une certaine quantité d'un fluide caloporteur à l'intérieur du circuit fermé constitué par les conduits 14 et 16 et par les raccords 18 et 20. Ce fluide caloporteur, par exemple un fréon ou de l'ammoniaque est vaporisable dans les conditions de fonctionnement de l'appareil. La tubulure 18 sert pour le départ de la vapeur vers le condenseur, tandis que la tubulure 20 sert pour le retour du liquide caloporteur vers l'évaporateur.FIG. 2 shows a first embodiment of the cold production apparatus according to the invention. This device consists of a first panel 10 forming a radiating surface whose radiation falls into at least one window of transparency of the atmosphere, a second panel 12 immersed substantially vertically in the material of the storage enclosure. A coil-shaped conduit 14 is formed on the panel 10. A conduit 16 substantially identical to the conduit 14 is formed on the panel 12. The end 14a of the conduit 14 is connected to the end 16a of the conduit 16 by a connector 18 In the same way, the end 14b of the conduit 14 is connected to the end 16b of the conduit 16 by a connector 20. The connector 20 comprises a filling nozzle 22 by which a certain amount of a heat transfer fluid is introduced. inside the closed circuit formed by the conduits 14 and 16 and by the connections 18 and 20. This heat transfer fluid, by example a freon or ammonia is vaporizable under the operating conditions of the device. The tube 18 is used for the departure of the steam to the condenser, while the tube 20 is used for the return of the heat transfer liquid to the evaporator.

On réalise ainsi un dispositif de type caloduc jouant le rôle d'une diode thermique dont le fonctionnement est le suivant. Lorsque, du fait de son rayonnement à travers les fenêtres de transparence de l'atmosphère, le panneau 10 fonctionnant comme. surface rayonnante subit un refroidissement, 'un transfert de chaleur se produit par effet caloduc du panneau 12 vers la surface rayonnante 10 et par conséquent, vers l'atmosphère : une certaine quantité de fluide caloporteur se vaporise à l'intérieur du panneau évaporateur 12. La vapeur ainsi formée se déplace par le conduit 16, puis par le raccord 18 jusque vers le panneau 10, plus froid, qui joue le rôle de condenseur. L'appareil produit donc du froid et l'emmagasine.This produces a heat pipe type device playing the role of a thermal diode whose operation is as follows. When, due to its radiation through the transparency windows of the atmosphere, the panel 10 operates as. radiating surface undergoes cooling, a transfer of heat occurs by the heat pipe effect panel 12 toward the radiating surface 10 and consequently to the atmosphere: a certain amount of coolant evaporates within the evaporator 12 panel. The vapor thus formed travels through the conduit 16, then through the connector 18 to the cooler panel 10, which acts as a condenser. The device therefore produces cold and stores it.

Dans l'hypothèse inverse, c'est-à-dire lorsque le panneau 10 se trouve à une température supérieure à celle du panneau 12, la totalité du fluide caloporteur se trouvant dans le panneau 12, un transfert de chaleur par effet caloduc est bloqué. Seul reste possible un transfert de chaleur par conduction. Cependant,comme on le sait, l'importance d'un tel transfert de chaleur reste très limitée.In the opposite hypothesis, that is to say when the panel 10 is at a temperature higher than that of the panel 12, all of the heat transfer fluid being in the panel 12, a heat transfer by heat pipe effect is blocked. . Only a heat transfer by conduction remains possible. However, as is known, the importance of such heat transfer remains very limited.

Comme on peut le constater, la liaison thermique entre le matériau de stockage et le panneau évaporateur 12 est améliorée du fait de la présence du conduit 16 en forme de serpentin sur toute la surface de l'évaporateur. D'une manière identique, la liaison thermique entre le conduit 14 et le panneau condenseur est améliorée.As can be seen, the thermal bond between the storage material and the evaporator panel 12 is improved due to the presence of the duct 16 in the form of a serpentine over the entire surface of the evaporator. In an identical manner, the thermal connection between the duct 14 and the condenser panel is improved.

L'appareil peut être réalisé suivant le procédé "Roll Bond" qui consiste à déposer par impression (genre rotative pour journaux) une peinture sur une feuille métallique ; on place ensuite une autre feuille métallique et on colamine à chaud l'ensemble. Il se produit une moulure par diffusion sauf aux endroits recouverts de peinture. On crée ensuite une pression qui décole les parties non soudées. Les . panneaux 10 et 12 peuvent être constitués par des panneaux condenseurs d'usage courant dans l'industrie frigorifique. Par conséquent, le coût de l'appareil est diminué. L'encombrement au cours du transport est également diminué, ce qui permet une réduction du coût de ce transport.The apparatus can be produced according to the "Roll Bond" process which consists in depositing by printing (rotary type for newspapers) a paint on a metal sheet; another metal sheet is then placed and the whole is hot-rolled. Diffusion molding occurs except in areas covered with paint. A pressure is then created which detaches the non-welded parts. The . panels 10 and 12 can be formed by condenser panels commonly used in the refrigeration industry. Therefore, the cost of the device is decreased. The space requirement during transport is also reduced, which allows a reduction in the cost of this transport.

Les raccords 18 et 20 sont réalisés en un matériau déformable plastiquement, par exemple en cuivre ou en aluminium recuit, ce qui permet, de ployer et de déployer l'ensemble un certain nombre de fois sans risque de fuites ou de ruptures. La structure ainsi obtenue est dite "portefeuille" par opposition à la structure de l'appareil selon l'art antérieur décrit précédemment dite "parapluie ouvert". L'encombrement au cours du transport est ainsi réduit.The connections 18 and 20 are made of a plastically deformable material, for example copper or annealed aluminum, which makes it possible to fold and deploy the assembly a certain number of times without risk of leaks or ruptures. The structure thus obtained is called "portfolio" as opposed to the structure of the device according to the prior art described above, called "open umbrella". The space requirement during transport is thus reduced.

On a représenté sur la figure 3 une variante de réalisation de l'appareil représenté sur la figure 2. Cet appareil est réalisé en un seul panneau qui remplit simultanément les fonctions de condenseur dans sa partie supérieure 10, et d'évaporateur dans sa partie inférieure 12. Les zones 10 et 12 sont séparées par des ajours 24 qui permettent d'isoler thermiquement l'évaporateur 12 du condenseur 10. Les raccords 18 et 20 du mode de réalisation précédent sont ainsi supprimés, le circuit fermé à l'intérieur duquel se trouve le fluide caloporteur étant réalisé en une seule partie. Seul reste nécessaire l'embout de remplissage 22 pour le fluide caloporteur.There is shown in Figure 3 an alternative embodiment of the device shown in Figure 2. This device is made in a single panel which simultaneously fulfills the functions of condenser in its upper part 10, and evaporator in its lower part 12. The zones 10 and 12 are separated by openings 24 which make it possible to thermally isolate the evaporator 12 from the condenser 10. The connections 18 and 20 of the previous embodiment are thus eliminated, the closed circuit inside which finds the heat transfer fluid being produced in a single game. Only the filling nozzle 22 remains necessary for the heat transfer fluid.

Ce panneau peut également être réalisé suivant le procédé "Roll Bond".This panel can also be produced using the "Roll Bond" process.

Cet appareil simple et peu coûteux peut être utilisé sur de très grandes surfaces, et il est intéressant de le présenter sous forme modulaire. Une telle réalisation est représentée sur la figure 4.This simple and inexpensive device can be used on very large surfaces, and it is interesting to present it in modular form. Such an embodiment is shown in FIG. 4.

Sur cette figure, le panneau formé en une seule pièce décrit en référence à la figure 3 est accroché par un rebord 26 obtenu par le pliage de l'extrémité du panneau 10 à un flotteur 28. La forme du flotteur 28 qui peut être réalisée par exemple en polystyrène expansé, est déterminée de façon à épouser celle du panneau et à donner à l'ensemble l'assiette souhaitée en fonction des données géographiques et topographiques du lieu d'implantation. Des appareils modulaires, tels que celui qui est représenté sur la figure 4, tous identiques mais totalement indépendants les uns des autres peuvent être juxtaposés pour couvrir en totalité une surface aussi grande qu'on le désire.In this figure, the panel formed in one piece described with reference to Figure 3 is hung by a flange 26 obtained by folding the end of the panel 10 to a float 28. The shape of the float 28 which can be produced by example in expanded polystyrene, is determined so as to match that of the panel and to give the whole the desired base according to the geographic and topographical data of the location. Modular devices, such as that which is represented in FIG. 4, all identical but completely independent of each other can be juxtaposed to completely cover an area as large as desired.

Ils peuvent être chargés en fluide caloporteur à l'issue de leur fabrication et transportés soit à plat avec une mise en forme sur le lieu d'utilisation, leur ceintrage facilité par la pression interne exercée par le fluide caloporteur étant obtenu au moyen d'un outillage approprié, soit après mise en forme sur les lieux de fabrication, en les imbriquant les uns dans les autres.They can be loaded with heat transfer fluid at the end of their manufacture and transported either flat with shaping at the place of use, their bending facilitated by the internal pressure exerted by the heat transfer fluid being obtained by means of a appropriate tools, either after shaping on the manufacturing site, by nesting them in one another.

Lorsque ces panneaux sont réalisés en aluminium ou en alliage d'aluminium, comme c'est le cas lorsqu'ils sont fabriqués par le procédé "Roll Bond", la surface rayonnante peut être obtenue directement à peu de frais par un traitement d'oxydation anodique exécuté après le remplissage en fluide caloporteur et le scellement du panneau.When these panels are made of aluminum or aluminum alloy, as is the case when they are manufactured by the "Roll Bond" process, the radiant surface can be obtained directly at low cost by an oxidation treatment anode performed after filling with heat transfer fluid and sealing the panel.
