Abstract

The bag (1) is made from transparent plastics sheet. This bag is preformed to act as a converging lens when filled with water. The bag is heat-sealed around its periphery (4) and supported in a frame. The solar rays (R) pass through the lens and converge at a focal point (F). A reflector mirror (D) is provided at this point and the concentrated rays are reflected to one side and are focused onto a suitable solar heating panel (E). This solar panel is normally connected to a boiler.

Description

l'invention concerne un dispositif de récupération de l'énergie solaire du type formé d'un système optique convergent *
On connalt déjà des dispositifs tels que des lentilles permettant ia recapération de l'énergie solaire. Ainsi, la lentille de lavoisier est formée de parois rigides transparentes présentant des faces convexes, cette lentille contenant un liquide constitué par de 11 esprit de vin.the invention relates to a device for recovering solar energy of the type formed by a convergent optical system *
Already known devices such as lenses allowing ia recovery of solar energy. Thus, the lavoisier lens is formed of transparent rigid walls having convex faces, this lens containing a liquid consisting of 11 spirit of wine.

On connaît également des lentilles plus récentes permettant de concentrer les rayons lumineux. Ces lentilles sont également formées par des parois rigides transparentes et contenant de l'eau. De telles lentilles ne peuvent être appliquées à la récupération de l'énergie solaire, car le prix de fabrication de ces lentilles, en raison des parois rigides, est extr8mement élevé. More recent lenses are also known which make it possible to concentrate the light rays. These lenses are also formed by transparent rigid walls containing water. Such lenses cannot be applied to the recovery of solar energy, because the manufacturing price of these lenses, due to the rigid walls, is extremely high.

La présente invention a donc pour but de remédier à ces inconvénients et se propose de créer un dispositif de récupération de l'énergie solaire formé d'un système optique convergent de conception simple, d'une grande efficacité et d'un prix de revient extremement bas
A cet effet, l'invention concerne un dispositif de récupération de l'énergie solaire formé dgun système optique convergent caractérisé en ce qulil est constitué d'au moins une enveloppe souple remplie de liquide, traversée par les rayons solaires convergeant vers un foyer.The present invention therefore aims to remedy these drawbacks and proposes to create a solar energy recovery device formed by a convergent optical system of simple design, high efficiency and extremely low cost low
To this end, the invention relates to a device for recovering solar energy formed by a convergent optical system characterized in that it consists of at least one flexible envelope filled with liquid, traversed by the solar rays converging towards a focus.

Suivant ce dispositif, c'est le liquide qui détermine la forme géométrique du système convergent. According to this device, it is the liquid which determines the geometric shape of the converging system.

Suivant une autre caractéristique de l'invention, l'en- veloppe est constituée de deux feuilles planes de matière souple collées à leur périphérie. According to another characteristic of the invention, the envelope consists of two flat sheets of flexible material glued at their periphery.

Suivant une autre caractéristique de l'invention, les deux feuilles sont en matière synthétique thermosoudées à leur périphérie. According to another characteristic of the invention, the two sheets are made of heat-sealed synthetic material at their periphery.

Suivant une autre caractéristique de l'invention, les deux feuilles en matière synthétique sont préformées pour constituer un système optique de convexité déterminée par rapport au foyers
Suivant une autre caractéristique de l'invention, le dispositif comporte au moins un déflecteur disposé à proximité du foyer. According to another characteristic of the invention, the two sheets of synthetic material are preformed to form an optical system of convexity determined with respect to the focal points
According to another characteristic of the invention, the device comprises at least one deflector arranged near the hearth.

Suivant une autre caractéristique de l'invention, le dispositif comporte un échangeur de chaleur pour absorber les faisceaux lumineux réfléchis par le déflecteur. According to another characteristic of the invention, the device comprises a heat exchanger for absorbing the light beams reflected by the deflector.

Suivant une autre caractéristique de l'invention, plusieurs systèmes optiques sont disposés en batterie, les déflecteurs réfléchissant les faisceaux lumineux vers un même échangeur de chaleur. According to another characteristic of the invention, several optical systems are arranged in a battery, the deflectors reflecting the light beams towards the same heat exchanger.

Suivant une autre caractéristique de l'invention, les systèmes optiques sont montés sur un dispositif d'orientation par rapport au soleil. According to another characteristic of the invention, the optical systems are mounted on an orientation device relative to the sun.

Suivant une autre caractéristique de l'invention, les systèmes optiques constituent des lentilles. According to another characteristic of the invention, the optical systems constitute lenses.

La présente invention sera mieux comprise à l'aide des modes de réalisation d'un dispositif de récupération de l'énergie solaire conforme à ltinvention, représentés schématiquement à titre d'exemple non limitatif, sur les dessins ci-joints, dans lesquels
- la figure 1 est un schéma dgun premier mode de réalisation du dispositif
- la figure 2 est un second mode de réalisation du dispositif.The present invention will be better understood using the embodiments of a solar energy recovery device according to the invention, shown diagrammatically by way of nonlimiting example, in the attached drawings, in which

R du soleil traversent la lentille convexe 1 et convergent vers le foyer F Un déflecteur D est disposé à proximité du foyer F Il a our fonction de réfléchir les rayons R vers l'échangeur de chaleur E qui est constitué par exemple par un élément de chaudière
Les feuilles 2, 3 de la lentille 1 peuvent également être réalisées en matière synthétique préformée pour constituer une lentille de convexité déterminée par rapport au foyer F.According to Figure 1, the solar energy recovery device is formed of a convergent lens 1. This lens is formed by two flat and flexible sheets 2 and 3 constituting an envelope intended to receive a liquid. the flexible sheets 2, 3 can be made of a synthetic material such as plastics and are bonded to their periphery 4 by heat sealing. The envelope formed by the sheets 2, 3 contains a liquid such as water, which makes it possible to lower the return cost of the lens. the Rays
R of the sun pass through the convex lens 1 and converge towards the focal point F A deflector D is arranged near the focal point F It has our function to reflect the rays R towards the heat exchanger E which is constituted for example by a boiler element
The sheets 2, 3 of the lens 1 can also be made of preformed synthetic material to constitute a lens of convexity determined relative to the focus F.

Selon la figure 2, les lentilles 1, non représentées dans cette fi rez sont montées sur un cadre 5 constituant un module.  According to Figure 2, the lenses 1, not shown in this fi fi are mounted on a frame 5 constituting a module.

les lentilles sont donc assemblées en batterie Les aéflecteurs
D, disposés à proximité du foyer de chaque lentille, réfléchis sant les faisceaux lumineux vers un même échangeur de chaleur 7.the lenses are therefore assembled in a battery The aflectors
D, arranged near the focal point of each lens, reflected on the light beams towards the same heat exchanger 7.

les lentilles prises isolément ou bien disposées en batterie sont montées sur un dispositif d'orientation par rapport au soleil, ceci afin dtaccroitre l'efficacité du dispositif de récupération de l'énergie solaire.  the lenses taken individually or else arranged in a battery are mounted on a device for orientation relative to the sun, this in order to increase the efficiency of the device for recovering solar energy.
