Description

"Collecteur solaire à pile photosltaque
L'invention concerne un collecteur solaire comprenant au moins une pile photovoltaique pour tirer parti de l'énergie du soleil."Photovoltaic battery solar collector
The invention relates to a solar collector comprising at least one photovoltaic cell for taking advantage of the sun's energy.

Les cellules ou piles photovoltaïques doivent être enveloppées d'une gaine transparente étanche à l'air afin d'être protégées de la corrosion atmosphérique. Pour cette raison, elles sont normalement enfermées entre des plaques de verre ou de matière plastique que l'on colle ensemble sur les bords. Les plaques de matière plastique ont pour inconvénients de perdre de leur transparence au cours du vieillissement et en outre, d'être plus ou moins perméables à lthumidité.  Photovoltaic cells or cells must be wrapped in a transparent airtight sheath in order to be protected from atmospheric corrosion. For this reason, they are normally enclosed between sheets of glass or plastic which are glued together at the edges. The plastic sheets have the drawbacks of losing their transparency during aging and, moreover, of being more or less permeable to humidity.

Dans les plaques de verre collées sur les bords, il se produit des tensions sous l'effet de la chaleur solaire qui entrainent des fêlures et ensuite des défectuosités par corrosion. Un autre inconvénient des enveloppements courants aujourd'hui est l'échauffement de la couche photovoltaïque pendant le fonctionnement qui diminue le rendement énergétique et accélère le vieillissement.In the glass plates glued on the edges, tensions occur under the effect of the solar heat which cause cracks and then defects by corrosion. Another drawback of current wraps today is the heating of the photovoltaic layer during operation which decreases energy efficiency and accelerates aging.

L'objet de l'invention est de réaliser un collecteur solaire du type mentionné pour qu'il puisse assurer une utilisation optimum de l'énergie solaire incidente, tout en présentant une construction simple et compacte ainsi qu'une grande facilité d'entretien. The object of the invention is to provide a solar collector of the type mentioned so that it can ensure optimum use of the incident solar energy, while having a simple and compact construction as well as great ease of maintenance.

A cet effet, l'inxentfon propose que la cellule photovoltaique soit disposée, dans un tube de verre fermé de façon étanche au vide, sur un support métallique, qui de son côté est relié d'une façon conductrice de la chaleur avec un tube qui peut être refroidi directement, ou indirectement. Le support peut être ici, de préférence, une tôle de cuivre. On pourra au choix, soit faire le vide dans le tube de verre, soit le remplir d'un gaz inerte. Le refroidissement du support métallique s'opère au moyen d'un tube métallique qui lui est relié d'une façon conductrice de la chaleur et qui, ou bien est parcouru par un liquide de refroidissement, ou bien est réalisé sous la forme d'un tube chauffant qui emmène la chaleur prélevée à l'intérieur du tube de verre. To this end, Inxentfon proposes that the photovoltaic cell be placed, in a glass tube closed in a vacuum-tight manner, on a metal support, which in turn is connected in a heat conductive manner with a tube which can be cooled directly, or indirectly. The support can be here, preferably, a sheet of copper. You can either choose to empty the glass tube or fill it with an inert gas. The cooling of the metal support takes place by means of a metal tube which is connected to it in a heat conductive manner and which either is traversed by a coolant, or is produced in the form of a heating tube which takes the heat taken from inside the glass tube.

Dans un autre mode de réalisation de l'invention, il peut être disposé, au choix, soit sur la face supérieure seule, soit sur la face supérieure et sur la face inférieure du support, au moins une cellule voltaique. Ce dernier cas exige qu'en dessous du plan du support métallique, en dehors du tube de verre, il soit disposé au moins une surface formant miroir qui réfléchisse les rayons du soleil sur la cellule photo voltaïque disposée sur la face inférieure du support métallique. Dans une autre configuration particulièrement intéressante le tube métallique sui se trouve dans le collecteur peut être parcouru par un agent refroidissant que fait circuler une pompe entrainée électriquement. In another embodiment of the invention, it can be arranged, as desired, either on the upper face alone, or on the upper face and on the lower face of the support, at least one voltaic cell. The latter case requires that below the plane of the metal support, apart from the glass tube, there is disposed at least one surface forming a mirror which reflects the rays of the sun on the photovoltaic cell arranged on the underside of the metal support. In another particularly advantageous configuration, the metal tube which is located in the collector can be traversed by a cooling agent which circulates an electrically driven pump.

La pompe est ici alimentée électriquement par au moins une des cellules photovoltaïques.The pump is here electrically powered by at least one of the photovoltaic cells.

D'autres détails, avantages, et caractéristiques de l'invention ressortiront de l'exemple de réalisation recommandé représenté dans le dessin annexé. Other details, advantages and characteristics of the invention will emerge from the recommended embodiment shown in the attached drawing.

Dans un collecteur solaire 10 est posée horizontalement, sur le plan central d'un tube de erre 12, une tôle porteuse 14, qui est couverte sur ses faces supérieures et inférieures d'au moins une cellule photo voltaïque 16 et 18. Il est relié solidairement avec le support métallique 14, qui est fait de préférence de cuivre, un tuyau 20, notamment du type radiateur, qui en fait le tour, par où peut circuler un fluide refroidissant. En-dessous du tube de verre 12 se trouve un dispositif optique 22 en forme de miroir destiné à réfléchir les rayons sur la cellule photovoltaique 18 qui se trouve en-dessous. La cellule photovoltaique inférieure 18 donnera un rendement d'autant meilleur que l'ouverture optique du
Jeu de miroirs 22 sera plus grande par rapport à sa surface.In a solar collector 10 is placed horizontally, on the central plane of a glass tube 12, a carrier sheet 14, which is covered on its upper and lower faces with at least one photovoltaic cell 16 and 18. It is connected integrally with the metal support 14, which is preferably made of copper, a pipe 20, in particular of the radiator type, which goes around it, through which a cooling fluid can circulate. Below the glass tube 12 is an optical device 22 in the form of a mirror intended to reflect the rays on the photovoltaic cell 18 which is located below. The lower photovoltaic cell 18 will give an efficiency all the better as the optical aperture of the
Set of mirrors 22 will be larger compared to its surface.

La canalisation électrique qui évacue le courant fourni par les cellules photoxoltaIques 16 et 18 peut être utilisée pour faire fonctionner une pompe entrat- née électriquement, qui n'est pas représentée et qui envoie le fluide de refroidissement dans le tube métallique 20 placé à l'intérieur. Cette disposition est particulièrement
Judicieuse Si l'on fait fonctionner un collecteur solaire 10 suivant l'invention, en commun avec une installation thermosolaire destinée à chauffer un liquide, car la puissance d'un seul collecteur suffit pour assurer la circulation de l'agent refroidissant dans de nombreux collecteurs. De ce fait, les installations d'eau de consommation, et de chauffage opératoire avec circulation forcée d'agent de refroidissement, sont indépendantes de toute alimentation extérieure d'énergie électrique. The electrical pipe which drains the current supplied by the photo-photovoltaic cells 16 and 18 can be used to operate an electrically driven pump, which is not shown and which sends the coolant into the metal tube 20 placed at the interior. This provision is particularly
Judicious If a solar collector 10 according to the invention is operated, in common with a thermosolar installation intended to heat a liquid, because the power of a single collector is sufficient to ensure the circulation of the cooling agent in numerous collectors . As a result, the drinking water and operational heating installations with forced circulation of coolant are independent of any external supply of electrical energy.
