Description

MODULE DE REFROIDISSEMENT DE PANNEAU THERMIQUE 1. Domaine de l' invention  THERMAL PANEL COOLING MODULE 1. Field of the invention
La présente invention concerne un dispositif de refroidissement pouvant assurer le refroidissement notamment de surfaces chaudes telles qu'un panneau photovoltaïque mais également de toute surface chaude ou de l'air ambiant.  The present invention relates to a cooling device that can provide cooling including hot surfaces such as a photovoltaic panel but also any hot surface or ambient air.
L' invention concerne également un tel dispositif qui permette de récupérer la chaleur des surfaces.  The invention also relates to such a device which makes it possible to recover the heat from the surfaces.
2. Solutions de l'art antérieur  2. Solutions of the prior art
Il est connu, par exemple pour le refroidissement de panneaux photovoltaïques , de mettre en œuvre un dispositif de dissipation de chaleur comprenant une pluralité de tuyaux parallèles en contact avec le panneau et venant s'encastrer dans des lames, ou ailettes, ménagées au voisinage des extrémités de ces tuyaux, sur ces tuyaux. Ainsi, les tuyaux récupèrent la chaleur accumulée par le panneau photovoltaïque et le transmettent aux ailettes par conduction, c'est-à-dire par contact entre deux entités de manière à réaliser un échange thermique entre ces deux entités. Les ailettes évacuent ensuite la chaleur dans l'air ambiant par convection.  It is known, for example for the cooling of photovoltaic panels, to implement a heat dissipating device comprising a plurality of parallel pipes in contact with the panel and coming to fit into blades, or fins, formed in the vicinity of ends of these pipes, on these pipes. Thus, the pipes recover the heat accumulated by the photovoltaic panel and transmit it to the fins by conduction, that is to say by contact between two entities so as to achieve a heat exchange between these two entities. The fins then evacuate the heat into the surrounding air by convection.
Un inconvénient d'une telle technique est que le refroidissement du panneau photovoltaïque n'est pas effectué sur toute la surface du panneau ce qui n'est pas optimal car certaines zones de ce panneau, en l'occurrence celles qui ne sont pas en contact direct avec les tuyaux, seront moins refroidies que les zones en contact direct avec les tuyaux qui sont refroidies par convection.  A disadvantage of such a technique is that the cooling of the photovoltaic panel is not performed on the entire surface of the panel which is not optimal because certain areas of this panel, in this case those which are not in contact direct with the pipes, will be less cooled than the areas in direct contact with the pipes that are cooled by convection.
Un autre inconvénient d'une telle technique est que la vitesse de refroidissement du panneau n'est pas optimale. En effet, le refroidissement étant principalement effectué par conduction, il est conditionné par la conductivité thermique des tuyaux ainsi que de la zone de contact entre ces tuyaux et la surface à refroidir Another disadvantage of such a technique is that the cooling rate of the panel is not optimal. Indeed, the cooling being mainly carried out by conduction, it is conditioned by the thermal conductivity of the pipes as well as the contact zone between these pipes and the surface to be cooled.
Encore un autre inconvénient d'une telle technique est que la chaleur transmise de la surface à refroidir, c'est-à-dire du panneau, est évacuée dans l'air ambiant (convection) , et n'est donc pas récupérée après, ce qui engendre un réchauffement de l'air ambiant ainsi qu'un gaspillage relativement important. En effet, cette énergie étant relâchée dans l'air, elle n'est pas employée à des fins utiles ce qui n'est pas satisfaisant.  Yet another disadvantage of such a technique is that the heat transmitted from the surface to be cooled, that is to say the panel, is discharged into the ambient air (convection), and is therefore not recovered after, which leads to a warming of the ambient air and a relatively large waste. Indeed, this energy being released in the air, it is not used for useful purposes which is not satisfactory.
On connaît également du document US2012/0009455 des modules de refroidissement de batterie mettant en œuvre des lames, sous la forme d' entretoises séparant deux cellules, composées de deux parties et présentant un profil en « L », l'échange de chaleur se faisant au contact des lames.  Also known from US2012 / 0009455 are battery cooling modules using blades, in the form of spacers separating two cells, composed of two parts and having an "L" profile, the heat exchange being effected. in contact with the blades.
Un inconvénient de cette technique est que le passage de la chaleur de chacune des cellules vers la lame avoisinante va être conditionné par le contact entre la lame et la cellule ce qui n'est pas optimal du fait que la qualité de ce contact est difficilement maîtrisable (dépendant des conditions de fabrication, de manipulation, ...) . De ce fait, un contact imparfait et donc une surface de contact limitée réduit l'échange de chaleur, et donc le refroidissement de la cellule ce qui n'est pas satisfaisant .  A disadvantage of this technique is that the passage of heat from each cell to the neighboring blade will be conditioned by the contact between the blade and the cell which is not optimal because the quality of this contact is difficult to control (depending on the conditions of manufacture, manipulation, ...). As a result, an imperfect contact and therefore a limited contact surface reduces the heat exchange, and therefore the cooling of the cell which is not satisfactory.
Un autre inconvénient de cette technique est qu' il n'y a pas de possibilité de récupération de chaleur par la suite, l'énergie récupérée étant évacuée dans l'air ambiant . Another disadvantage of this technique is that there is no possibility of heat recovery thereafter, the recovered energy being discharged into the air ambient.
3. Objectifs de l'invention  3. Objectives of the invention
L'invention a notamment pour objectif de résoudre les inconvénients de l'art antérieur.  The invention particularly aims to solve the disadvantages of the prior art.
Plus particulièrement un objectif d'au moins un mode de réalisation de l'invention est de fournir un dispositif de refroidissement de surface permettant d'optimiser le refroidissement d'une surface donnée en agissant sur toute la surface à refroidir.  More particularly, an objective of at least one embodiment of the invention is to provide a surface cooling device for optimizing the cooling of a given surface by acting on the entire surface to be cooled.
Un autre objectif d'au moins un mode de réalisation est de fournir une technique qui permet d'optimiser le transport d'énergie par convection et par conduction.  Another objective of at least one embodiment is to provide a technique that optimizes convective and conductive energy transport.
Encore un autre objectif d'au moins un mode de réalisation est de fournir une technique permettant d'optimiser l'énergie récupérée par le refroidissement.  Yet another object of at least one embodiment is to provide a technique for optimizing the energy recovered by cooling.
Un autre objectif d'au moins un mode de réalisation de l'invention est de fournir un dispositif qui soit peu coûteux et simple à mettre en œuvre.  Another objective of at least one embodiment of the invention is to provide a device that is inexpensive and simple to implement.
4. Résumé de l'invention  4. Summary of the invention
Ces objectifs, ainsi que d'autres qui apparaîtront par la suite, sont atteints à l'aide d'un dispositif de refroidissement d'une surface à refroidir, le dispositif comprenant :  These objectives, as well as others which will appear later, are achieved by means of a device for cooling a surface to be cooled, the device comprising:
- une surface de refroidissement en contact continu avec la zone à refroidir ;  a cooling surface in continuous contact with the zone to be cooled;
- une pluralité de lames reliées à la surface.  a plurality of blades connected to the surface.
Selon l'invention, le dispositif comprend en outre au moins un tube de refroidissement traversant la pluralité de lames.  According to the invention, the device further comprises at least one cooling tube passing through the plurality of blades.
Ainsi, l'invention propose une approche nouvelle et inventive permettant d'optimiser le refroidissement d'une zone en mettant en œuvre une surface de refroidissement en contact continu avec cette zone et en prévoyant un tube de refroidissement traversant des lames, ou ailettes, en contact avec la surface de refroidissement. De ce fait, le refroidissement et donc le transfert d'énergie est effectué de manière optimale par convection et par conduction . Thus, the invention proposes a new and inventive approach for optimizing the cooling of an area by implementing a cooling surface in continuous contact with this zone and providing a cooling tube through blades, or fins, in contact with the cooling surface. As a result, the cooling and therefore the energy transfer is optimally effected by convection and conduction.
Dans un mode de réalisation particulier, les lames comprennent une première partie et une deuxième partie jointes par une arête. Par ailleurs, pour deux lames successives données, la deuxième partie de la première lame est au contact de la deuxième partie de la deuxième lame, les deuxièmes parties formant une portion de la surface de refroidissement.  In a particular embodiment, the blades comprise a first portion and a second portion joined by an edge. Moreover, for two given successive blades, the second portion of the first blade is in contact with the second portion of the second blade, the second portions forming a portion of the cooling surface.
Ainsi, cela permet d'optimiser le refroidissement en limitant le nombre d'épaisseurs à traverser pour la chaleur. En effet, le fait que la surface de refroidissement soit « confondue » avec les lames permet à ces lames de capter directement la chaleur et de la diffuser à travers leur première partie et à travers le tube de refroidissement.  Thus, this optimizes the cooling by limiting the number of thicknesses to be crossed for the heat. Indeed, the fact that the cooling surface is "confused" with the blades allows these blades to directly capture the heat and diffuse through their first part and through the cooling tube.
Dans ce cas, et pour deux lames successives données, la deuxième partie de la première lame peut recouvrir au moins partiellement la deuxième partie de la deuxième lame.  In this case, and for two given successive blades, the second portion of the first blade can at least partially cover the second portion of the second blade.
Ainsi, cela permet d'éviter que deux lames soient écartées l'une de l'autre par les contraintes et/ou les tolérances de fabrication. De ce fait, le contact est continu entre deux lames successives ce qui permet par conséquent d'assurer l'optimisation du refroidissement de la zone en contact avec la surface de refroidissement.  Thus, this prevents two blades are spaced from each other by the constraints and / or manufacturing tolerances. As a result, the contact is continuous between two successive blades, which consequently makes it possible to optimize the cooling of the zone in contact with the cooling surface.
Dans un mode de réalisation de l'invention, le tube de refroidissement traverse les lames au niveau des premières parties. In one embodiment of the invention, the cooling tube passes through the blades at the level of first parts.
Ainsi, cela permet d'évacuer la chaleur accumulée par la première partie, ladite chaleur correspondant à la chaleur diffusée par la deuxième partie de chaque lame au niveau de la première partie.  Thus, it allows to evacuate the heat accumulated by the first part, said heat corresponding to the heat diffused by the second part of each blade at the first part.
Selon des variantes de l'invention, la deuxième partie de chacune des lames forme un angle compris entre 85° et 95° avec la première partie, et peut même être sensiblement égal à 90°.  According to variants of the invention, the second part of each of the blades forms an angle of between 85 ° and 95 ° with the first part, and may even be substantially equal to 90 °.
Ainsi, cela permet de fournir différentes mises en œuvre de l'invention permettant de s'adapter aux conditions d'utilisation ainsi qu'aux applications.  Thus, this makes it possible to provide different implementations of the invention making it possible to adapt to the conditions of use as well as to the applications.
Dans un mode de réalisation particulier, l'arête présente un profil arrondi.  In a particular embodiment, the edge has a rounded profile.
Ainsi, cela permet de faciliter l'emboutissage d'une telle pièce, notamment lors d'une étape de pliage d'une pièce plane afin d'obtenir une lame telle que mise en œuvre dans l'invention.  Thus, this facilitates the stamping of such a part, especially during a folding step of a flat piece to obtain a blade as implemented in the invention.
Dans une variante de l'invention, les lames présentent une épaisseur sensiblement constante et comprise entre 0,1 et 0,3 mm.  In a variant of the invention, the blades have a substantially constant thickness and between 0.1 and 0.3 mm.

6. Description détaillée  6. Detailed description
On présente maintenant, en relation avec les figures 1 à 4, un premier mode de réalisation d'un dispositif de refroidissement selon l'invention.  A first embodiment of a cooling device according to the invention is now presented with reference to FIGS. 1 to 4.
Comme illustré sur ces figures, le dispositif de refroidissement 1, ou module de refroidissement, comprend une pluralité de lames 4 (autrement appelées lamelles ou ailettes) formées d'une première partie 41 et d'une deuxième partie 42, ces parties étant jointes par une arête 43. Les lames 4 présentent un profil sensiblement en « L », les première 41 et deuxième 42 parties formant respectivement le long côté et le petit côté du L et la deuxième partie 42 formant un angle a sensiblement égal à 90° avec la première partie 41. Bien évidemment on peut prévoir d'autres modes de réalisation dans lesquels l'angle a entre la première partie 41 et la deuxième partie 42 serait plus généralement compris entre 85° et 95°. On peut même prévoir des angles supérieurs à 95° ou inférieurs à 85° de manière à s'adapter aux utilisations du dispositif de refroidissement 1. On peut également prévoir des variantes dans lesquelles la première partie correspondrait au petit côté du L tandis que la deuxième partie correspondrait au grand côté du L. As illustrated in these figures, the cooling device 1, or cooling module, comprises a plurality of blades 4 (otherwise called lamellae or fins) formed of a first part 41 and a second part 42, these parts being joined by an edge 43. The blades 4 have a profile substantially in "L", the first 41 and second 42 parts forming respectively the long side and the short side of the L and the second part 42 forming an angle substantially equal to 90 ° with the first part 41. Of course we can provide other embodiments in which the angle α between the first portion 41 and the second portion 42 would more generally be between 85 ° and 95 °. It is even possible to provide angles greater than 95 ° or less than 85 ° so as to adapt to the uses of the cooling device 1. It is also possible to provide variants in which the first part corresponds to the short side of the L while the second part part would correspond to the big side of L.
Dans cet exemple, l'arête 43 présente un profil arrondi de manière à faciliter l'emboutissage. En effet, de manière à conférer aux lames leur profil en L, celles- ci sont pliées. Ainsi, une forme arrondie de l'arête s'obtient simplement lors du pliage. Un tel profil sur la lame finie permet ainsi de limiter les étapes de fabrication et par conséquent les coûts. Cependant, on peut également prévoir des variantes de l'invention dans lesquels l'arête présente un profil différent. On peut également prévoir des modes de réalisation dans lesquels les deux parties seraient soudées entre elles.  In this example, the edge 43 has a rounded profile so as to facilitate the stamping. Indeed, so as to give the blades their L profile, they are folded. Thus, a rounded shape of the edge is obtained simply during folding. Such a profile on the finished blade thus limits the manufacturing steps and therefore the costs. However, it is also possible to provide variants of the invention in which the edge has a different profile. Embodiments may also be provided in which the two parts are welded together.
Dans le mode de réalisation des figures 1 à 4, les lames présentent une épaisseur E sensiblement constante et comprise entre 0,1 et 0,3 millimètres. Bien évidemment, on peut prévoir des ailettes présentant une épaisseur différente dans d'autres modes de réalisation.  In the embodiment of Figures 1 to 4, the blades have a substantially constant thickness E and between 0.1 and 0.3 millimeters. Of course, it is possible to provide fins having a different thickness in other embodiments.
Ces lames 4 peuvent être fabriquées en aluminium tel que de l'aluminium hydrophile ou de l'aluminium pré peint. Elles peuvent également être constituées de cuivre ou d'un alliage de cuivre tel que du cuivre étamé. These blades 4 can be made of aluminum such as hydrophilic aluminum or aluminum pre painted. They may also be made of copper or a copper alloy such as tinned copper.
Comme illustré, les lames 4 sont reliées à une surface de refroidissement 3 en contact continu avec une zone à refroidir 2. Dans le mode de réalisation des figures 1 à 4, la surface de refroidissement 3 est formée par l'ensemble des deuxièmes parties 42 des lames 4. Cela permet ainsi d'optimiser le refroidissement en mettant en oeuvre une surface continue, et cela peut également améliorer la vitesse « d'évacuation » de la chaleur vers les ailettes en limitant le nombre d'épaisseurs à traverser par la chaleur. En effet, le fait que la surface de refroidissement 3 soit « confondue » avec les lames 4 permet à ces lames 4 de capter directement la chaleur de la zone à refroidir 2 et de la diffuser à travers leurs premières parties 41. Ces lames 4 sont placées telles que pour deux lames successives 4', 4'' données, la deuxième partie 42' de la première lame 4' recouvre partiellement la deuxième partie 42'' de la deuxième lame 4'' . De cette manière, on évite que deux lames, et en particulier deux deuxièmes parties successives, soient écartées l'une de l'autre. Ainsi, le contact est assuré entre les lames ce qui permet un refroidissement optimal de la zone à refroidir 2. L'épaisseur des lames, qui est relativement faible, permet d'obtenir une surface de refroidissement (composée des deuxièmes parties 42 des lames 4) sensiblement plane. En d'autres le fait d'avoir une épaisseur de lame relativement faible fait que la superposition de deux lames ne va pas engendrer un « rebord » trop important, ce rebord étant formé par une première lame située en dessous d'une deuxième lame adjacente qui est superposée à cette première. Dans cet exemple, les différentes lames sont espacées deux à deux d'une distance D sensiblement constante et comprise entre 1mm et 6mm, cette distance pouvant bien sûr être différente de cette plage de valeurs et pouvant être non constante dans des variantes de 1 ' invention . As illustrated, the blades 4 are connected to a cooling surface 3 in continuous contact with an area to be cooled 2. In the embodiment of FIGS. 1 to 4, the cooling surface 3 is formed by all the second parts 42 4. This thus makes it possible to optimize the cooling by implementing a continuous surface, and this can also improve the speed of "evacuation" of the heat towards the fins by limiting the number of thicknesses to be traversed by the heat. . Indeed, the fact that the cooling surface 3 is "merged" with the blades 4 allows these blades 4 to directly capture the heat of the zone to be cooled 2 and to diffuse through their first portions 41. These blades 4 are placed such that for two successive blades 4 ', 4''data, the second portion 42' of the first blade 4 'partially covers the second portion 42''of the second blade 4''. In this way, it avoids two blades, and in particular two second successive parts, are spaced apart from each other. Thus, the contact is provided between the blades which allows an optimal cooling of the zone to be cooled 2. The thickness of the blades, which is relatively low, provides a cooling surface (composed of the second parts 42 of the blades 4 ) substantially flat. In others the fact of having a relatively small blade thickness makes the superposition of two blades will not generate a "rim" too large, this flange being formed by a first blade located below a second adjacent blade which is superimposed on this first. In this example, the different blades are spaced two by two by a distance D substantially constant and between 1mm and 6mm, this distance may of course be different from this range of values and may be non-constant in variants of one invention .
Bien évidemment, on pourrait également prévoir des modes de réalisation dans lesquels les deuxièmes parties de deux lames successives sont plus ou moins superposées. On peut également prévoir des modes de réalisation dans lesquels les deuxièmes parties de deux ailettes successives seraient simplement au contact l'une de l'autre sans être superposées.  Of course, one could also provide embodiments in which the second parts of two successive blades are more or less superimposed. Embodiments may also be provided in which the second portions of two successive fins are simply in contact with one another without being superposed.
On pourrait également imaginer des modes de réalisation dans lesquels la surface de refroidissement 3 serait distincte des lames 4 et ne serait donc pas formée par les deuxièmes parties 42 de lames 4, mais serait en contact avec les lames 4. On peut en outre imaginer des modes de réalisation dans lesquels les lames ne seraient pas formées de deux parties mais d'une unique partie 41, par exemple soudée à la surface de refroidissement 3 à une de ses extrémités, et formant un angle entre 0° et 180° avec la surface de refroidissement 3.  One could also imagine embodiments in which the cooling surface 3 would be distinct from the blades 4 and would not be formed by the second parts 42 of the blades 4, but would be in contact with the blades 4. It can furthermore be conceived of embodiments in which the blades would not be formed of two parts but a single portion 41, for example welded to the cooling surface 3 at one of its ends, and forming an angle between 0 ° and 180 ° with the surface cooling 3.
Comme illustré sur ces figures 1 à 4, le dispositif de refroidissement 1 comprend en outre un tube de refroidissement 5 qui traverse la pluralité de lames 4, au niveau des premières parties 41 de ces lames 4. Ce tube peut être constitué d'un matériau tel que du cuivre (qui peut être par exemple lisse ou rainuré) ou d'aluminium. Dans ce mode de réalisation, le tube 5, autrement appelé circuit de tube ou tuyau de refroidissement, présente un diamètre compris entre 6 et 18 mm par exemple. Il peut être, selon les variantes, formé de plusieurs sections de tuyaux ou être un unique tuyau présentant un profil en « serpentin », employé classiquement dans des systèmes tels que les radiateurs. As illustrated in these Figures 1 to 4, the cooling device 1 further comprises a cooling tube 5 which passes through the plurality of blades 4, at the first portions 41 of these blades 4. This tube may consist of a material such as copper (which may be for example smooth or grooved) or aluminum. In this embodiment, the tube 5, otherwise called tube circuit or cooling pipe, has a diameter of between 6 and 18 mm for example. he can be, according to the variants, formed of several sections of pipes or be a single pipe having a "serpentine" profile, conventionally used in systems such as radiators.
Ce tube 5 traverse chaque lame, au niveau des premières parties 41, de manière à créer un circuit de refroidissement à proximité de la surface de refroidissement 3, qui va capter la chaleur accumulée par les ailettes. A l'intérieur de ce tube 5 circule un fluide caloporteur, c'est-à-dire un fluide capable de transporter la chaleur accumulée lors du refroidissement de la zone à refroidir 2. Ainsi, l'énergie thermique récupérée par les lames 4 est transmise par conduction au fluide circulant dans le tube 5. Ce fluide caloporteur est par exemple de l'eau sous forme liquide ou à l'état de vapeur, un liquide tel que du fréon, ou un gaz tel que de l'air. Ce tube 5 peut être placé au contact de moyens de récupération de chaleur (non représentés) qui coopèrent avec le dispositif de refroidissement 1 de sorte que la chaleur accumulée (provenant de la chaleur récupérée au niveau de la zone à refroidir 2) dans le dispositif de refroidissement 1 soit récupérée dans ces moyens et puisse être utilisée par exemple comme moyen de production de chauffage ou de production d'eau chaude sanitaire via un dispositif d' échangeur pour accumulation par exemple.  This tube 5 passes through each blade, at the first portions 41, so as to create a cooling circuit near the cooling surface 3, which will capture the heat accumulated by the fins. Inside this tube 5 circulates a coolant, that is to say a fluid capable of transporting the heat accumulated during cooling of the zone to be cooled 2. Thus, the thermal energy recovered by the blades 4 is transmitted by conduction to the fluid flowing in the tube 5. This heat transfer fluid is for example water in liquid form or in the vapor state, a liquid such as freon, or a gas such as air. This tube 5 can be placed in contact with heat recovery means (not shown) which cooperate with the cooling device 1 so that the heat accumulated (from the heat recovered at the zone to be cooled 2) in the device 1 is recovered in these means and can be used for example as a means for producing heating or production of domestic hot water via a storage exchanger device for example.
Bien évidemment, on peut prévoir des modes de réalisation dans lesquels le dispositif posséderait plusieurs circuits de tubes, autrement appelées nappes, ménagées de telle sorte qu'elles traversent la première lame à différents niveaux, c'est-à-dire sans se croiser. On peut en outre, dans ce cas, prévoir des variantes dans lesquelles les différentes nappes présenteraient un mode de fonctionnement différent, à savoir une nappe à l'intérieur de laquelle circule de l'air et une autre nappe à l'intérieur de laquelle circule de l'eau. On ne limite bien évidemment pas les combinaisons de nappes à ce dernier exemple. Of course, it is possible to provide embodiments in which the device would have several tube circuits, otherwise called layers, arranged so that they pass through the first blade at different levels, that is to say without crossing. In this case, it is also possible to envisage variants in which the different layers would have a different mode. different operating, namely a sheet inside which circulates air and another sheet inside which circulates water. Of course, the combinations of layers are not limited to this last example.
On présente maintenant, en relation avec la figure 5, un autre mode de réalisation, dans lequel le dispositif de refroidissement est mis en œuvre au sein d'un panneau solaire thermique.  Another embodiment is presented in connection with FIG. 5, in which the cooling device is implemented within a solar thermal panel.
Comme illustré sur cette figure, le panneau solaire thermique 7 comprend une plaque thermique 71. De manière à refroidir cette plaque 71, soit en d'autres termes de manière à emmagasiner l'énergie accumulée par la plaque 71, le panneau thermique 7 comprend un dispositif de refroidissement 1 placé au contact de la plaque 71. Le dispositif de refroidissement, similaire dans cet exemple au dispositif de refroidissement des figures 1 à 4, comprend une seule nappe 5 ainsi qu'une pluralité de lames 4 dont les deuxième parties forment une surface de refroidissement en contact continu avec la plaque 71 et les premières parties permettent une circulation d' air ambiant à proximité des lames et de la surface de refroidissement, de manière à récupérer la chaleur accumulée par la plaque 71 par conduction et par convection.  As illustrated in this figure, the solar thermal panel 7 comprises a thermal plate 71. In order to cool this plate 71, in other words so as to store the energy accumulated by the plate 71, the thermal panel 7 comprises a cooling device 1 placed in contact with the plate 71. The cooling device, similar in this example to the cooling device of FIGS. 1 to 4, comprises a single ply 5 as well as a plurality of blades 4 whose second parts form a cooling surface in continuous contact with the plate 71 and the first parts allow a flow of ambient air near the blades and the cooling surface, so as to recover the heat accumulated by the plate 71 by conduction and by convection.
De même que précédemment, ce panneau thermique peut coopérer avec des moyens de récupération de chaleur disposés au contact du tube 5 de sorte que l'énergie récupérée puisse servir, par exemple, de moyen de chauffage d'air ambiant ou d'eau.  As before, this thermal panel can cooperate with heat recovery means arranged in contact with the tube 5 so that the recovered energy can be used, for example, means for heating ambient air or water.
Dans d'autres variantes de l'invention, on pourrait également prévoir que le dispositif de refroidissement soit inclus dans des systèmes tels qu'un panneau solaire photovoltaïque comprenant une plaque munie de cellules photovoltaïques . In other variants of the invention, it could also be provided that the cooling device is included in systems such as a photovoltaic solar panel comprising a plate provided with photovoltaic cells.
