Abstract

The solar collector comprises groups of polycarbonate tunnels of semicircular section which concentrate solar rays onto a metal tube carrying a working fluid. Auxiliary collector plates on either side of the main collector fill the base of the semicircle and collect the diffused energy. The semicircular tunnel (2) is set onto a base plate. The base plate supports the main collector tube which is of trapezoidal section and is covered by a semicircular cover to reduce heat loss. On either side of the inner cover two flat plates (1) run parallel to the main collector and are slightly angled towards the centre to collect diffused solar rays. The outer tunnel (2) is fixed to the base and has groups of Fresnel lines moulded onto its outer surface.

Description

L'objet de l'invention concerne un dispositif de capteur scolaire à concentration e
I est destiné à permettre la captation du rayonnement solaire direct et diffus afin d'obtenir un réchaui- fement du fluide à moyenne et haute température0
Dans les dispositifs connus de ce genre avec concentration, on utilise des ensembles cylindriques paraboliques offrant au vent des prises considérables et demandant des renforcements porteurs importants et encombrants ainsi qu'inesthétiques. The object of the invention relates to a school sensor device with concentration e
I is intended to allow the capture of direct and diffuse solar radiation in order to obtain a warming of the fluid at medium and high temperature
In known devices of this kind with concentration, parabolic cylindrical assemblies are used which offer considerable grips to the wind and which require substantial and bulky as well as unattractive load-bearing reinforcements.

Ils provoquent des réflexions gOnantes et éblouis santes, sont d'un entretien difficile et présentent dee pertes de calories importantes aussi bien dans les zones de captation, que dans les éléments de transmission, toutefois l'un des inconvénients les plus importants, est que ces appareils sont mobiles pour suivre la course du soleil et ne peuvent de ce fait former un ensemble couvrant compaot pour réaliser une toiture normale. They provoke dazzling and dazzling reflections, are difficult to maintain and have significant loss of calories both in the capture areas and in the transmission elements, however one of the most important drawbacks is that these devices are mobile to follow the course of the sun and can not therefore form a whole covering compaot to achieve a normal roof.

Le dispositif suivant l'invention supprime ces inconvénients et permet non seulement de réaliser une toiture fixe, stable et isolante, conservant l'aspect courant et la couleur des tuiles en s'adaptant à tous lee environnements mais encore, de présenter une efficacité de réchaui fement accrue par la. possibilité d'utiliser chaque profil semi-circulaire de la surface couvrante comme zones de concentrations dans un meme module afin de capter les rayonnements sur 1800, avec leurs intensités progressives et dégressives sans solution de continuité dans latransmission des calories
I1 est constitué par des plaques ondulées en matitre rigide et transparente formées par des secteurs semi- circulaires avec méplats de fixation porteurs et séparateurs et par la confection sur les périphéries externes de chaque seoteur semi-sphérique de réseaux de Freenel linéaires multiples, concentrant le rayonnement solaire sur 1800 sur un tube concentrique transparent enveloppant une canalisation métallique réceptrice des points focaux sur ses faces orientées combinées avec deux capteurs horizontaux sy6tri ques, pour captation des rayonnements diffus.The device according to the invention eliminates these drawbacks and makes it possible not only to produce a fixed, stable and insulating roof, retaining the current appearance and the color of the tiles by adapting to all the environments, but also to present a warming efficiency. greatly increased by. possibility of using each semi-circular profile of the covering surface as areas of concentration in the same module in order to capture the radiation over 1800, with their progressive and decreasing intensities without a solution of continuity in the transmission of calories
It is made up of corrugated rigid and transparent sheets formed by semicircular sectors with supporting and separating fixing flats and by making multiple linear Freenel networks on the outer peripheries of each semi-spherical segment, concentrating the radiation solar system on 1800 on a transparent concentric tube enveloping a metal pipe receiving focal points on its oriented faces combined with two horizontal sy6tric sensors, for capture of diffuse radiation.

Sur les dessins annexés, donnés à titre d'expia ple non limitatif, d'une des formes de réalisation de l'objet de l'invention :
La figure 1 montre les plaques transparentes couvrantes.In the appended drawings, given by way of non-limiting example, of one of the embodiments of the object of the invention:
Figure 1 shows the transparent covering plates.

La figure 2 est une vue en coupe des éléments montrant l'ensemble du dispositif. Figure 2 is a sectional view of the elements showing the entire device.

La figure 3 est une vue en coupe de la structure portante et du dispositif de nettoyages
Les plaques ondulées 1, figure 1 comportent plusieurs secteurs semi-circulaires 2,
Ces éléments sont rigides, transparents et peuvent entre en polycarbonate ou autres substances appropriées
Ces surfaces semi-circulaires ayant environ 1800 comportent figure 2, plusieurs zones de diffraction 4, 5, 6, et concentrant en un seul point le rayonnement solaire qui les contacte. Ce rayonnement se focalise sur une plage de réception qui suivant le déplacement du soleil peut titre momentanément situé successivement aux points 7, 8, 9 Concentriquement au recouvrement transparent 2,et placé un élément tubulaire transparent 10. Figure 3 is a sectional view of the supporting structure and the cleaning device
The corrugated plates 1, FIG. 1 comprise several semi-circular sectors 2,
These elements are rigid, transparent and can come in polycarbonate or other suitable substances
These semi-circular surfaces having approximately 1800 comprise figure 2, several diffraction zones 4, 5, 6, and concentrating in a single point the solar radiation which contacts them. This radiation is focused on a reception area which, depending on the movement of the sun, may momentarily be located successively at points 7, 8, 9 Concentrically to the transparent covering 2, and placed a transparent tubular element 10.

Cet élément avec secteur circulaire a une base plans A l'intérieur de ce tube transparent est disposé un tube capteur 11, comportant plusieurs surfaces de réception 12, 13, 14, orientées formant un ensemble de plusieurs plages de travail linéaires
Dans ce tube 11 circule le fluide caloporteur.This element with circular sector has a flat base. Inside this transparent tube is arranged a sensor tube 11, comprising several receiving surfaces 12, 13, 14, oriented forming a set of several linear working areas.
In this tube 11 circulates the heat transfer fluid.

Deux capteurs 15, 16 plans absorbent le rayonnement diffus. Ils sont indépendants du tube récepteur 11. Two sensors 15, 16 planes absorb the diffuse radiation. They are independent of the receiving tube 11.

Le concentrateur ondulé 1 comporte dans chaque forme demi-rondes 2, 3 et une série de réseaux Fresnel 4, 5, 6 et autres, taillés en parallèles et linéaires. The corrugated concentrator 1 comprises in each half-round shape 2, 3 and a series of Fresnel networks 4, 5, 6 and others, cut in parallel and linear.

Ils sont indépendants en ce qui concerne la focalisation du moment. La zone chauffante sans solution de continuité passe par les secteurs 7, 8, 9, de façon à assurer une transmission de calories continues. They are independent with regard to the focusing of the moment. The heating zone without continuity solution passes through the sectors 7, 8, 9, so as to ensure a transmission of continuous calories.

Xes plaques 1 avec les méplats 17, 18 reposent sur une structure auto-portable 19 oui assure le maintien, l'étanchéité et l'isolation du dispositif figure 3. Xes plates 1 with the flats 17, 18 rest on a self-portable structure 19 yes ensures the maintenance, the sealing and the insulation of the device figure 3.

On peut éventuellement utiliser un système de nettoyage mont sur organes de roulement 20, 21, 22, avec projection d'eau 952 24 qui peut mécaniquement maintenir la transparence des surfaces couvrantes et polarisées. It is possible to use a cleaning system mounted on rolling members 20, 21, 22, with water spray 952 24 which can mechanically maintain the transparency of the covering and polarized surfaces.

Par ce dispositif le rayonnement solaire du lever au coucher est capté et concentrés Il traverse le tube transparent qui piège un maximum de calories et vient aboutir sur le tube métallique0
Sur ce tube qui correspond un foyer, on obtient de 130 à 2000 centigrades qui échauffent le fluide calopor tueur,
Les capteurs latéraux 16, 17 qui recoivent les rayonnements diffus produisent une eau à moyenne température pouvant 8tre utilisée pour le chauffage ou l'eau sanitai re
Ce méme dispositif est utilisable pour la produc tion du froid suivant les procédés connus,
Il permet en tout état de cause d'assurer à la fois la couverture étanche statique et structurée d'un bf- timent et le chauffage centrals
Il donne la possibilité de réaliser la production de vapeur, la climatisation avec isolation thermique
Toutefois les formes, dimensions et dispositiona des différents éléments, comme d'ailleurs les matières utilisées pour leur fabrication pourront varier dans la limite des équivalents, comme d'ailleurs les matières utilisées pour leur fabrication, sans changer pour cela la conception générale de l'invention qui vient d'8tre décrite By this device, the solar radiation from sunrise to sunset is captured and concentrated. It passes through the transparent tube which traps a maximum of calories and comes to end on the metal tube.
On this tube which corresponds to a hearth, we obtain 130 to 2000 centigrade which heat the killer heat transfer fluid,
The lateral sensors 16, 17 which receive diffuse radiation produce medium temperature water which can be used for heating or sanitary water.
This same device can be used for the production of cold according to known methods,
In any case, it provides both static and structured waterproof cover for a building and central heating
It gives the possibility of producing steam, air conditioning with thermal insulation
