Abstract

The solar collector (1) consists of a long enclosure of triangular cross section. The base and the back are insulated (2) and have highly reflective inner surfaces (3). The inclined surface of the enclosure is transparent in order to admit the solar radiation. The absorber (4) is a thin-walled vessel arranged along the bisecting axis of the right angle between the base and the back. The absorber is mfrd. from a high conductivity material cooled by the flow of water within it. The inner volume of the enclosure is evacuated to offset the build up of pressure due to expansion.

Description

La présente invention concerne les dispositifs destinés à capter l'énergie solaire pour des besoins domestiques. The present invention relates to devices intended to collect solar energy for domestic needs.

Les appareils connus de ce genre sont généralement munis de serpentins dans lesquels circulent de l'eau. Ces serpentin s forment des boucles parallètles entre-elles et sont positionnés généralement dans un caisson plat. Known devices of this kind are generally provided with coils in which water circulates. These coils form loops parallel to each other and are generally positioned in a flat box.

Le caisson est fait avec des matériaux isolants, pos sédant peu de profondeur et, est recouvert de verre, afin de créer le phénomène de serre. The box is made with insulating materials, pos sedating little depth and, is covered with glass, in order to create the greenhouse phenomenon.

L'inconvénient majeur de ces capteurs, actuellement fabriqués, réside dans le fait qu'une surface relativement importante des serpentins n'est pas touchée par les rayons du soleil, ce qui donne un petit rendement calorifique. The major drawback of these sensors, currently manufactured, lies in the fact that a relatively large surface area of the coils is not touched by the sun's rays, which gives a small calorific output.

La forme plate des caissons en fait des appareils très encombrants, inesthétiques et se prêtant mal.à la manutention
Compte-tenu que le rendement calorifique est fonction pour un certain pourcentage de la surface réceptrice du capteur, ca paramètre augmente proportionnellement les inconvénients susmentionnés.The flat shape of the boxes makes them very bulky, unsightly and ill-suited to handling.
Given that the heat output is a function for a certain percentage of the receiving surface of the sensor, this parameter proportionally increases the above-mentioned drawbacks.

Le dispositif objet de l'invention est réalisé de manière à supprimer totalement les zones d'ombre, il en résulte que le réservoir est touché sur toute sa surface par les rayons du soleil, ce qui permet un très bon rendement calorifique. La conception du dispositif de la présente demande permet de réduire son encombrement et de ce fait, s'intègre mieux dans un ensemble de construction. The device which is the subject of the invention is produced in such a way as to completely remove the shadow areas, it follows that the tank is affected over its entire surface by the rays of the sun, which allows a very good calorific output. The design of the device of the present application makes it possible to reduce its bulk and therefore, fits better into a construction assembly.

Le dispositif objet de l'invention comporte un caisson caractérisé par sa forme longitudinale de section triangulaire, ce caisson possède deux côtés égaux réalisés dans un matériau très bon isolant thermique et, est fermé aux deux extrémités. Le troisième côté est constitué par un matériau transparent tels que du verre, ou plastique pour laisser pénétrer les rayons du soleil. Un conteneur mince et plat est fixé par un de ses côtés longitudinaux dans l'axe de la bissectrice de l'angle formé par les deux côtés isolants du caisson. Ce conteneur est réalisé dans un matériau très bon conducteur de la chaleur dans lequel circule un liquide qui communique avec un échangeur selon le procédés actuellement utilisés, munis de thermostat, d'accélérateur, etc... The device which is the subject of the invention comprises a box characterized by its longitudinal shape of triangular section, this box has two equal sides made of a very good thermal insulating material and is closed at both ends. The third side is made of a transparent material such as glass, or plastic to allow the rays of the sun to penetrate. A thin and flat container is fixed by one of its longitudinal sides in the axis of the bisector of the angle formed by the two insulating sides of the box. This container is made of a material which is a very good conductor of heat in which a liquid circulates which communicates with an exchanger according to the methods currently used, provided with thermostat, accelerator, etc.

Les faces intérieures situées de part et d'autre du conteneur sont recouvertes d'un matériau à haut pouvoir réfléchissant, tel que argent, ou d'un miroir. En cours de montage, la pression intérieure du caisson est réduite, pour éviter lors du fonctionnement, que les gaz par dilatation dépassent la pression atmosphérique normale. The interior faces located on either side of the container are covered with a material with high reflecting power, such as silver, or with a mirror. During assembly, the internal pressure of the box is reduced, to prevent during operation that the gases by expansion exceed normal atmospheric pressure.

Selon une variante de l'invention, le liquide circulant dans le conteneur peut renfermer un fluide possédant un haut pouvoir d'absorption. According to a variant of the invention, the liquid circulating in the container can contain a fluid having a high absorption power.

Selon une autre variante de l'invention, le conteneur pourra comporter des orifices afin de permettre une meilleure circulation de l'air dans le caisson. According to another variant of the invention, the container may include orifices in order to allow better circulation of the air in the box.

Selon une autre variante de réalisation, les faces intérieures réfléchissantes peuvent avoir une forme hyperbolique. According to another alternative embodiment, the reflecting internal faces can have a hyperbolic shape.

Seloniune autre variante de réalisation, les extrémités du caisson peuvent:-avoir léur facè:.intériéureoréfléchis- sante. According to another alternative embodiment, the ends of the box can: have a facet:. Interior reflective.

Les dessins annexés illustrent a titre d'exemple non limitatif, un mode de réalisation du dispositif conforme à la présente invention. The accompanying drawings illustrate by way of nonlimiting example, an embodiment of the device according to the present invention.

La figure 1 représente irone coupe transversale du capteur solaire. Figure 1 shows irone cross section of the solar collector.

La figure 2 représente une vue longitudinale partielle du caisson avec le conteneur. Figure 2 shows a partial longitudinal view of the box with the container.

Tel que représenté en figures 1 et 2, le dispositif comporte un caisson 1, triangulaire avec deux parois 2 égales qui forment entre-elles un angle voisin de 900. La face intérieure de chaque paroi 2 est recouverte d'un miroir 3. Un conteneur 4 de forme plate est fixé dans l'angle opposé au côté 5, transparent. As shown in Figures 1 and 2, the device comprises a box 1, triangular with two equal walls 2 which form between them an angle close to 900. The inner face of each wall 2 is covered with a mirror 3. A container 4 of flat shape is fixed in the opposite corner to side 5, transparent.

Le côté 5, transparent, peut être constitué d'un double vitrage qui sera fixé par tout moyen approprié de manière à assurer une étanchéité parfaite à l'air et aux intempéries et de créer l'effet de serre. Side 5, transparent, may consist of double glazing which will be fixed by any appropriate means so as to ensure perfect airtightness and weatherproofing and to create the greenhouse effect.

Le caisson 1 pourra être muni de photo-cellules as sa sant sur un mécanisme permettant d'orienter le côté 5 en permanence vers le soleil, de telle façon qu'il n'apparaisse qu'un minimum d'ombre sur les faces réfléchissantes. The box 1 may be provided with photo-cells having its health on a mechanism making it possible to orient the side 5 permanently towards the sun, so that there appears only a minimum of shade on the reflecting faces.

Le dispositif, objet de l'invention, peut être utilisé pour la captation de l'énergie solaire pour des besoins domestiques ou industriels.  The device, object of the invention, can be used for the capture of solar energy for domestic or industrial needs.
