Abstract

The solar panel consists of a black metal heat absorber covered by a black emitting layer (3) which exchanges heat trapped through a transparent insulated (double-glazed) partition (5, 6) directly with a heat transfer fluid. The panel is made from an assembly of rectangular tubes (1) and profiles (2) that allow a compact arrangement of the different components - a double-glazed unit with an inner vacuum, and a base (4) resting on compressed fibre glass insulation (10) in a housing (12) with a space (8) for the heat transfer fluid which is circulated through two manifolds with inlet and outlet pipes in the panel frame.

La présente invention concerne un appareil capteur solaire, dont les calories issues du rayonnement solaire sont transmises à un fluide caloporteur par un absorbeur constitué d'une fine plaque métallique (3/1) recouverte d'une couche de peinture à la base de graphite ou d'oxyde noir. The present invention relates to a solar collector device, the calories of which from solar radiation are transmitted to a heat-transfer fluid by an absorber consisting of a thin metal plate (3/1) covered with a layer of paint based on graphite or black oxide.

L'absorbeur est plongé directement dans un fluide caloporteur pur. The absorber is immersed directly in a pure heat transfer fluid.

Une ossature adaptée, constituée par un tube rectangulaire en alu ou acier inox (1/1) qui supporte un profilé du même métal (2/1) maintenu par soudure (18/1) reçoit dans sa partie supérieure un double vitrage 4-12-4mm, avec vide air (5 et 6/1) fixé par un élastomère haute température (7/1). A suitable frame, constituted by a rectangular tube of aluminum or stainless steel (1/1) which supports a profile of the same metal (2/1) held by welding (18/1) receives in its upper part double glazing 4-12 -4mm, with vacuum air (5 and 6/1) fixed by a high temperature elastomer (7/1).

Dans la partie inférieure du profilé, une plaque (4/1) est disposée et maintenue par soudure en périphérie, servant de fond et reposant sur une couche isolante (10/1). In the lower part of the profile, a plate (4/1) is arranged and held by welding on the periphery, serving as a bottom and resting on an insulating layer (10/1).

Entre le double vitrage et la plaque servant de fond, l'espace aménagé (8/1) sert au passage du fluide caloporteur introduit par des orifices percés dans le tube rectangulaire, et traversant le profilé (9/1). Between the double glazing and the plate serving as the bottom, the fitted space (8/1) is used for the passage of the heat transfer fluid introduced through holes drilled in the rectangular tube, and passing through the profile (9/1).

L'ossature comporte deux tubes rectangulaires (19/4) qui servent de collecteur et diffuseur du fluide caloporteur, entrant et sortant par des tubes filetés (20 et 21/4) soudés sur un flasque (17/3). Le tube (18/4) et son vis à vis sert de liaison à l'ossature. The framework comprises two rectangular tubes (19/4) which serve as collector and diffuser of the heat transfer fluid, entering and leaving by threaded tubes (20 and 21/4) welded on a flange (17/3). The tube (18/4) and its opposite serves as a connection to the frame.

L'ossature avec tous les éléments ci-dessus désignés, repose sur une isolation (10/1), qui est elle-même insérée dans une carcasse en métal, ou composite (12/1). The framework with all the above-mentioned elements rests on an insulation (10/1), which is itself inserted in a metal or composite carcass (12/1).

Un profilé (11/1) sert à refermer l'ensemble, au moyen de vis (13/1). A profile (11/1) is used to close the assembly, by means of screws (13/1).

Ce capteur solaire offrant très peu de déperditions, et l'absorbeur plongé dans le fluide caloporteur permettent d'obtenir des rendements élevés. This solar collector offering very little loss, and the absorber immersed in the heat transfer fluid allow high yields to be obtained.

Les dessins annexes illustrent l'invention, la figure 1 représente en coupe les différents éléments qui composent le capteur solaire. The accompanying drawings illustrate the invention, Figure 1 shows in section the different elements that make up the solar collector.

Dans l'espace crée entre le double vitrage et la pla- -rage et la pla- que de fond, est logée une fine plaque de métal recouverte de peinture à base de graphique ou d'oxyde noir (3/1), maintenue par des écarteurs (15/1). In the space created between the double glazing and the cladding and the bottom plate, is housed a thin metal plate covered with paint based on graphics or black oxide (3/1), maintained by spacers (15/1).

Le fluide qui circule dans l'espace (8/1) est admis par les orifices (9/1) aménagés dans le tube rectangulaire et le profilé, et rentre par un tube fileté (14/1).  The fluid which circulates in the space (8/1) is admitted through the orifices (9/1) arranged in the rectangular tube and the profile, and enters through a threaded tube (14/1).

L'ossature et les différents éléments reposent sur un isolant dense, type fibre de verre compressée (10/1).
