Description

ECHANGEUR DE CHALEUR SOLAIRE SOLAR HEAT EXCHANGER
La présente invention concerne un échangeur de chaleur solaire destiné au chauffage ou au refroidissement d'un fluide liquide ou gazeux. Une application particulière est le chauffage de l'eau alimentant une piscine.The present invention relates to a solar heat exchanger for heating or cooling a liquid or gaseous fluid. A particular application is the heating of the water supplying a swimming pool.
Le but de l'invention est de procurer un appareil qui soit de construction simple et de montage facile.The object of the invention is to provide an apparatus which is simple in construction and easy to assemble.
A cet effet, il est proposé un échangeur de chaleur solaire dans lequel la chambre destinée au passage d'un fluide est formée par une poche étanche constituée d'une feuille mince en matière imperméable, la poche présentant au moins un orifice pour l'introduction d'un fluide liquide ou gazeux dans la poche et au moins un orifice pour l'évacuation du fluide après son passage dans la poche.To this end, a solar heat exchanger is proposed in which the chamber intended for the passage of a fluid is formed by a sealed pocket made up of a thin sheet of waterproof material, the pocket having at least one orifice for the introduction of a liquid or gaseous fluid in the pocket and at least one orifice for the evacuation of the fluid after it has passed through the pocket.
Un tube distributeur peut être introduit dans le ou les orifices d'entrée, ledit tube distributeur étant percé d'orifices répartis sur sa longueur de manière à répar¬ tir le fluide sur toute la longueur de la poche. Un tube collecteur peut également être introduit dans le ou les orifices de sortie, ledit tube collecteur étant percé d'orifices répartis sur sa longueur de manière à recueillir le fluide sur toute la longueur de la poche.A distributor tube can be introduced into the inlet orifices, said distributor tube being pierced with orifices distributed over its length so as to repair the fluid over the entire length of the pocket. A collecting tube can also be introduced into the outlet orifices, said collecting tube being pierced with orifices distributed over its length so as to collect the fluid over the entire length of the pocket.
L'avantage de l'invention est que la poche formant la chambre peut être réalisée très simplement dans n'im- porte quelles dimensions s'adaptant aux besoins et au site. De plus, lorsqu'elle est réalisée en un matériau souple, la poche est pliable, ce qui en facilite le transport vers le site de montage.The advantage of the invention is that the pocket forming the chamber can be produced very simply in any carries what dimensions adapting to the needs and the site. In addition, when it is made of a flexible material, the pocket is foldable, which facilitates transport to the assembly site.
L'invention est exposée dans ce qui suit à l'aide des dessins joints.The invention is set out in the following with the aid of the accompanying drawings.
La figure 1 est une vue en perspective d'une partie d'un échangeur solaire suivant l'invention.Figure 1 is a perspective view of part of a solar exchanger according to the invention.
La figure 2 montre une vue avec arrachement d'une va¬ riante de réalisation de l'appareil suivant la figure 1.FIG. 2 shows a cutaway view of a variant embodiment of the apparatus according to FIG. 1.
Les figures 3 et 4 montrent des vues partielles avec arrachement de deux variantes d'exécution d'un détail d'un appareil selon la figure 2.Figures 3 and 4 show partial views with cutaway of two alternative embodiments of a detail of an apparatus according to Figure 2.
Se reportant à la figure 1 on voit qu'un échangeur de chaleur solaire selon l'invention consiste en une poche étanche 1 constituée d'une feuille mince en matière imperméable, présentant au moins deux orifices : au moins un orifice 2 pour l'introduction d'un fluide liquide ou gazeux à réchauffer ou à refroidir et au moins un orifice 3 pour l'évacuation du fluide réchauf- fé ou refroidi. La feuille a par exemple une épaisseur de 0,5 mm. La matière utilisée pour constituer la poche étanche peut être une matière souple, semi-rigide ou rigide. L'emploi d'une matière souple offre l'avan¬ tage que la poche peut être pliée pour le transport. Une face au moins est réalisée en couleur foncée.Referring to Figure 1 we see that a solar heat exchanger according to the invention consists of a sealed pocket 1 consisting of a thin sheet of impermeable material, having at least two orifices: at least one orifice 2 for the introduction of a liquid or gaseous fluid to be heated or cooled and at least one orifice 3 for the evacuation of the heated or cooled fluid. The sheet has for example a thickness of 0.5 mm. The material used to form the waterproof bag can be a flexible, semi-rigid or rigid material. The use of a flexible material offers the advantage that the pocket can be folded for transport. At least one side is made in dark color.
La poche 1 peut être facilement réalisée à partir d'une feuille repliée sur elle-même. Les côtés à rendre étanche sont alors soudés entre eux. Le bord 4 sur la figure 1 représente un bord soudé; le bord soudé opposé n'est pas représenté. La longueur de la poche peut être quelconque.The pocket 1 can be easily produced from a sheet folded back on itself. The sides to be sealed are then welded together. The edge 4 in FIG. 1 represents a welded edge; the opposite welded edge is not shown. The length of the pocket can be any.
Dans un mode de réalisation particulier illustré sur la figure 2, un tube distributeur 5 percé d'orifices 6 répartis sur sa longueur se trouve introduit dans le ou les orifices d'entrée 2 de manière à distribuer le fluide à réchauffer ou refroidir sur toute la longeur de la poche 1. Un tube collecteur 7, également percé d'orifices répartis sur sa longueur, se trouve intro¬ duit dans le ou les orifices de sortie 3 de manière à collecter le fluide réchauffé ou refroidi sur toute la longueur de la poche.In a particular embodiment illustrated in FIG. 2, a distributor tube 5 pierced with orifices 6 distributed over its length is inserted into the inlet orifice (s) 2 so as to distribute the fluid to be heated or cooled over the entire length of the pocket 1. A collecting tube 7, also pierced with orifices distributed over its length, is introduced into the outlet orifice (s) 3 so as to collect the heated or cooled fluid over the entire length of the pocket .
La poche 1 peut être fixée sur un support quelconque, stationnaire ou orientable. En fonctionnement, le fluide à réchauffer ou refroidir est introduit par le ou les orifices d'entrée 2, s'écoule dans la poche par ruissellement naturel ou par pression entre les parois 11 et 12 de la poche et est ensuite recueilli à l'ex¬ trémité opposée de la poche d'où il est évacué par le ou les orifices de sortie 3. Lorsqu'une paroi de la poche est exposée au soleil, le fluide se réchauffe au contact de cette paroi pendant son passage dans la poche. Lorsque, au contraire, une paroi de la poche est en contact avec de l'air froid, le fluide qui s'écoule en contact avec cette paroi se refroidit.The pocket 1 can be fixed on any support, stationary or orientable. In operation, the fluid to be heated or cooled is introduced through the inlet opening (s) 2, flows into the pocket by natural trickling or by pressure between the walls 11 and 12 of the pocket and is then collected ex ¬ opposite end of the pocket from which it is discharged through the outlet orifices 3. When a wall of the pocket is exposed to the sun, the fluid heats up in contact with this wall during its passage through the pocket. When, on the contrary, a wall of the pocket is in contact with cold air, the fluid which flows in contact with this wall cools.
Afin de guider l'écoulement du fluide dans la poche, celle-ci peut être pourvue intérieurement de nervures directrices s'étendant sur une partie de la hauteur de la poche entre le niveau des orifices d'entrée 2 et le niveau des orifices de sortie 3. La figure 3 montre, à échelle agrandie, un exemple de mode d'exécution dans lequel des nervures 8 sont fixées ou formées sur la face interne d'une paroi, par exemple la paroi 12, de la poche. Les nervures peuvent s'étendre en hauteur jusqu'à la paroi opposée 11. Le nombre de nervures et leur écartement peuvent être quelconques. La figure 4 illustre un exemple d'exécution dans lequel des nervu¬ res 9 sont fixées sur un tube distributeur de fluide 5.In order to guide the flow of fluid in the pocket, the latter can be provided internally with guiding ribs extending over part of the height of the pocket between the level of the inlet orifices 2 and the level of the outlet orifices. 3. FIG. 3 shows, on an enlarged scale, an exemplary embodiment in which ribs 8 are fixed or formed on the internal face of a wall, for example the wall 12, of the pocket. The ribs can extend in height up to the opposite wall 11. The number of ribs and their spacing can be any. FIG. 4 illustrates an exemplary embodiment in which ribs 9 are fixed on a fluid distributor tube 5.
Utilisée comme capteur solaire, la poche suivant l'in¬ vention peut être logée dans un coffre étanche muni d'un couvercle transparent fixe ou amovible afin de bénéficier de l'effet de serre.Used as a solar collector, the pocket according to the invention can be housed in a sealed trunk provided with a fixed or removable transparent cover in order to benefit from the greenhouse effect.
L'étendue de la poche peut être aisément adaptée aux besoins de l'application concernée sans qu'il en ré- suite de problème de fabrication. The size of the bag can be easily adapted to the needs of the application concerned without any manufacturing problem.
