Abstract

The solar collector uses a pump to circulate de-ionized water copper tube (2) wound in a spiral and fixed by clamps (10) to a metal plate (4) forming the bottom of the square box (1) housing the spiral. One face of the enclosure is covered by a transparent plastic screen which is exposed to the Sun. The internal walls (3) of the enclosure are chrome-plated.

Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

La présente invention concerne un dispositif solaire récupérateur de chaleur caractérisé par une circulation d'eau désionisée débarrassée des sels de calcium. Cette invention comporte une tubulure en cuivre aménagée en spirale dans un caisson.  The present invention relates to a solar heat recovery device characterized by a circulation of deionized water free of calcium salts. This invention comprises a copper tube arranged in a spiral in a box.

Dans cette tubulure circule de l'eau désionisée qui s'échauffe sous l'effet des rayons solaires traversant un panneau transparent fermant une des faces du caisson. In this tube circulates deionized water which heats up under the effect of solar rays passing through a transparent panel closing one of the faces of the box.

Actuellement, on connait divers dispositifs qui font appel à des principes similaires, comme par exemple la circulation d'eau entre deux panneaux transparents, ou ceux utilisant un liquide organique caloriporteur ayant une forte capacité d'absorption calorifique stockant la chaleur. Ces derniers dispositifs sont généralement associés à un échangeur de température en cuivre. Tous ces dispositifs sont onéreux et difficiles à mettre en oeuvre.  Currently, various devices are known which use similar principles, such as for example the circulation of water between two transparent panels, or those using an organic heat transfer liquid having a high heat absorption capacity storing heat. These latter devices are generally associated with a copper heat exchanger. All of these devices are expensive and difficult to implement.

Déjà dans le Certificat d'utilité français NO 95 08837 du 17/07/95, on avait imaginé un tube plastique absorbant l'énergie solaire, et ayant les propriétés d'un corps noir. Cette canalisation plastique était enroulée en spirale dans un caisson dont une face transparente était exposée au soleil ; ce dispositif avait l'inconvénient de s'entartrer rapidement. Already in the French Utility Certificate NO 95 08837 of 07/17/95, we had imagined a plastic tube absorbing solar energy, and having the properties of a black body. This plastic pipe was wound in a spiral in a box whose transparent face was exposed to the sun; this device had the disadvantage of scaling quickly.

La présente invention est caractérisée par une tubulure en cuivre (2) enroulée en spirale dans un caisson (1) dont l'une des faces est fermée par un panneau translucide (5). Cette tubulure de cuivre est fixée au fond (4) du caisson au moyen de brides (10).  The present invention is characterized by a copper tube (2) wound in a spiral in a box (1) one of the faces of which is closed by a translucent panel (5). This copper tubing is fixed to the bottom (4) of the box by means of flanges (10).

L'alimentation en liquide caloriporteur est obtenue au moyen d'eau désionisée par des résines échangeuses d'ions (15) placées à l'entrée du dispositif. L'eau pénètre au niveau (8) sur le plus grand diamètre de la spirale et circule au moyen d'une pompe (11) située à l'entrée du dispositif. The supply of heat transfer liquid is obtained by means of deionized water by ion exchange resins (15) placed at the inlet of the device. Water penetrates at level (8) over the largest diameter of the spiral and circulates by means of a pump (11) located at the inlet of the device.

<Desc/Clms Page number 2><Desc / Clms Page number 2>

L'eau chaude s'échappe au niveau (7) de la tubulure (2) reliant le petit diamètre de la spirale à la sortie de l'eau chaude. Le fond (4) du caisson (1) est isolé de la spirale de cuivre au moyen de laine de verre (9) par exemple, et les parois intérieures latérales (3) du caisson métallique (1) son chromées pour assurer une bonne réflexion thermique.  The hot water escapes at the level (7) of the tubing (2) connecting the small diameter of the spiral to the outlet of the hot water. The bottom (4) of the box (1) is isolated from the copper spiral by means of glass wool (9) for example, and the lateral interior walls (3) of the metal box (1) are chrome-plated to ensure good reflection thermal.

L'invention ainsi caractérisée sera mieux comprise grâce aux dessins annexés qui sont présentés à titre d'exemple dans une réalisation préférentielle de l'inventeur.  The invention thus characterized will be better understood from the accompanying drawings which are presented by way of example in a preferred embodiment of the inventor.

La figure 1 de la planche 1/2 représente le caisson contenant la spirale de cuivre.  Figure 1 of plate 1/2 represents the box containing the copper spiral.

La figure 2 de la planche 1/2 représente, en coupe, le caisson avec les éléments qu'il renferme.  Figure 2 of the plate 1/2 shows, in section, the box with the elements it contains.

La figure 3 de la planche 1/2 représente, en coupe, la bride de fixation de la tubulure de cuivre.  Figure 3 of the plate 1/2 represents, in section, the fixing flange of the copper tubing.

La figure 4 de la planche 2/2 représente un exemple d'installation du dispositif sur son socle.  Figure 4 of plate 2/2 shows an example of installation of the device on its base.

On a dessiné sur la figure 1 de la planche 1/2 le dispositif de récupération de chaleur solaire.  The solar heat recovery device has been drawn in FIG. 1 of plate 1/2.

Cette chaleur solaire est récupérée au moyen d'eau désionisée qui circule dans une tubulure de cuivre (2) enroulée en spirale et logée dans un caisson (1).  This solar heat is recovered by means of deionized water which circulates in a copper tube (2) wound in a spiral and housed in a box (1).

La circulation d'eau est assurée au moyen d'une pompe (11) placée au niveau (8) à l'entrée de la tubulure (2) sur le plus grand diamètre de la spirale. The circulation of water is ensured by means of a pump (11) placed at level (8) at the inlet of the tube (2) over the largest diameter of the spiral.

La sortie d'eau chaude (7) est connectée au centre de la spirale de la tubulure de cuivre (2). The hot water outlet (7) is connected to the center of the spiral of the copper tubing (2).

<Desc/Clms Page number 3> <Desc / Clms Page number 3>

La tubulure de cuivre (2) en forme de spirale est isolée de l'extérieur au moyen d'un caisson métallique (1) dont le fond intérieur (4) a reçu un isolant thermique type laine de verre (9), la tubulure (2) étant fixée au moyen de brides (10) solidaires de ce fond (4). The copper tubing (2) in the form of a spiral is isolated from the outside by means of a metal box (1), the internal bottom (4) of which has received a thermal insulator such as glass wool (9), the tubing ( 2) being fixed by means of flanges (10) integral with this bottom (4).

Les parois latérales intérieures (6) du caisson (1) réfléchissent les rayons solaires sur la tubulure de cuivre (2) au moyen d'une couche de chrome (3) déposée sur ses parois. The inner side walls (6) of the box (1) reflect the sun's rays on the copper tubing (2) by means of a layer of chromium (3) deposited on its walls.

On a représenté sur la figure 2 de la planche 1/2 le caisson vu en coupe.  There is shown in Figure 2 of the plate 1/2 the box seen in section.

La tubulure de cuivre (2) fixée sur le fond (4) du caisson est isolée de ce dernier au moyen de l'isolant (9) constitué de laine de verre. The copper tubing (2) fixed to the bottom (4) of the box is isolated from the latter by means of the insulator (9) made of glass wool.

Le caisson (1) est fermé au moyen d'un couvercle translucide (5) légèrement concave pour centrer les rayons solaires sur la tubulure de cuivre. The box (1) is closed by means of a translucent cover (5) slightly concave to center the solar rays on the copper tubing.

Les parois latérales (6) sont métalliques et sont rendues réfléchissantes au moyen d'un dépôt de chrome brillant (3). The side walls (6) are metallic and are made reflective by means of a deposit of shiny chrome (3).

On a représenté sur la figure 3 de la planche 1/2 la bride utilisée pour fixer la tubulure de cuivre au fond du caisson. Cette bride (10) enserre la tubulure de cuivre (2) de façon à ce que cette dernière puisse se dilater en diamètre et en longueur sans altérer son attache. La bride (10) est fixée au fond du caisson (4) par vissage ou soudage.  There is shown in Figure 3 of the plate 1/2 the flange used to fix the copper tubing to the bottom of the box. This flange (10) encloses the copper tubing (2) so that the latter can expand in diameter and length without altering its attachment. The flange (10) is fixed to the bottom of the box (4) by screwing or welding.

On a dessiné sur la figure 4 de la planche 2/2 l'ensemble du dispositif monté sur son socle (13) avec les accessoires.  The whole of the device mounted on its base (13) with the accessories has been drawn in FIG. 4 of the plate 2/2.

L'eau qui pénètre dans la tubulure de cuivre au niveau (8) est désionisée au moyen de résines échangeuses d'ions contenues dans le dit désioniseur (15).  The water which enters the copper tubing at level (8) is deionized by means of ion exchange resins contained in said deionizer (15).

<Desc/Clms Page number 4> <Desc / Clms Page number 4>

L'eau désionisée est entraînée au moyen d'une pompe à circulation (11) dans la tubulure de cuivre (2) au niveau du plus grand diamètre de la spirale. Cette eau sera reprise chaude par l'extrêmité (7) de la tubulure connectée au centre de la dite spirale de cuivre.  The deionized water is entrained by means of a circulation pump (11) in the copper tube (2) at the level of the largest diameter of the spiral. This water will be taken up hot by the end (7) of the tube connected to the center of the said copper spiral.

Le caisson (1) contenant le dispositif est orienté au moyen d'un socle (13) orientable au niveau des pivots (14) portés par les pieds (12). The box (1) containing the device is oriented by means of a base (13) orientable at the level of the pivots (14) carried by the feet (12).
