Néanmoins, compte tenu de l'utilisation particulière à laquelle les échangeurs selon l'invention sont destinés, à savoir le réchauffement d'eau de piscine et d'eau de mer, cette mesure n'est pas suffisante En effet, l'eau de piscine contient un agent oxydant, par exemple du chlore, et est donc corrosive. Le but de l'invention est donc de prévoir un However, given the particular use for which the exchangers according to the invention are intended, namely the heating of swimming pool and sea water, this measure is not sufficient. swimming pool contains an oxidizing agent, for example chlorine, and is therefore corrosive. The object of the invention is therefore to provide a

On a trouvé que l'on obtenait des résultats satisfaisants en prévoyant le corps externe dans un matériau à base de matière plastique et le tube du serpentin en titane, et en munissant le serpentin d'écarteurs entre la paroi externe de la virole et la It has been found that satisfactory results are obtained by providing the external body in a plastic material and the tube of the titanium coil, and by providing the coil with spacers between the external wall of the shell and the

The internal diameter of the sleeves 6 and 7 is dimensioned so that the exchanger can be

A l'intérieur du corps 1, coaxialement, est prévue une virole 8 constituée d'un tube cylindrique muni d'une cloison interne radiale 9. Dans l'espace annulaire entre la paroi interne du corps 1 et la paroi externe de la virole 8, est monté un serpentin 10 constitué d'un tube en hélice A son extrémité supérieure, le serpentin 10 se termine par un coude 11 traversant, avec étanchéité, le couvercle 2 et présente une entrée 12 par laquelle est introduit le fluide primaire A l'autre extrémité, le serpentin 10 forme un coude 13 prolongé par une partie rectiligne 14 traversant elle aussi le couvercle 2 avec étanchéité et débouchant, au voisinage de l'entrée 12, sur une sortie par laquelle sort le fluide primaire après avoir cédé ses calories La partie rectiligne 14 traverse également Inside the body 1, coaxially, a ferrule 8 is provided, consisting of a cylindrical tube provided with a radial internal partition 9. In the annular space between the internal wall of the body 1 and the external wall of the ferrule 8 , is mounted a coil 10 consisting of a helical tube At its upper end, the coil 10 ends in a through bend 11, with sealing, the cover 2 and has an inlet 12 through which the primary fluid is introduced other end, the coil 10 forms an elbow 13 extended by a rectilinear part 14 also passing through the cover 2 with sealing and opening, in the vicinity of the inlet 12, on an outlet through which the primary fluid leaves after having given up its calories La straight part 14 also crosses
la cloison interne 9 de la virole 8. the internal partition 9 of the shell 8.
La virole 8 est fixée sur le serpentin 10 par des The ferrule 8 is fixed to the coil 10 by
moyens appropriés (non représentés). appropriate means (not shown).
A l'extrémité inférieure du corps 1, est monté un capteur de température 16 dont le signal de sortie peut servir à la commande de la circulation des fluides At the lower end of the body 1, a temperature sensor 16 is mounted, the output signal of which can be used to control the circulation of fluids
primaire et secondaire dans l'échangeur. primary and secondary in the exchanger.
Selon l'invention, le corps 1 et la virole 8 sont constitués en un matériau à base de matière plastique, renforcé ou pas, tel que du PVC ou, avantageusement, du polyester armé de fibres de verre Le serpentin 10 est en titane. On a prévu, d'une part, entre la paroi interne du corps 1 et le serpentin 10, des écarteurs 17 a se présentant sous la forme d'une bande verticale de faible largeur par rapport au diamètre du corps 1 et pourvue de logements pour chacune des spires du serpentin 10 et, d'autre part, entre la paroi externe de la virole 8 et le serpentin 10, des écarteurs 17 b se présentant sous la forme d'une bande également de faible largeur par rapport au diamètre de la virole 8 Les écarteurs 17 a et 17 b maintiennent le serpentin 10 à une distance d'environ According to the invention, the body 1 and the ferrule 8 are made of a plastic-based material, reinforced or not, such as PVC or, advantageously, polyester reinforced with glass fibers. The coil 10 is made of titanium. There are provided, on the one hand, between the internal wall of the body 1 and the coil 10, spacers 17 a in the form of a vertical strip of small width compared to the diameter of the body 1 and provided with housings for each of the turns of the coil 10 and, on the other hand, between the outer wall of the shell 8 and the coil 10, spacers 17 b in the form of a strip also of small width relative to the diameter of the shell 8 The spacers 17 a and 17 b keep the coil 10 at a distance of approximately
2 mm et du corps 1 et de la virole 8. 2 mm and from body 1 and ferrule 8.
La fonction des écarteurs 17 a et 17 b est multiple. The function of the spacers 17 a and 17 b is multiple.
Elle est de faciliter le montage du serpentin 10 qui se présente, une fois les écarteurs 17 a mis en place, sous la forme d'une unique pièce rigide Elle est également d'éviter les mouvements relatifs entre, d'une part, le corps 1 et la virole 8 et, d'autre part, le serpentin 10, mouvements qui sont engendrés par des vibrations de pompes et accessoires environnant l'échangeur et qui peuvent entraîner des frottements qui détériorent les It is to facilitate the mounting of the coil 10 which is presented, once the spacers 17 have been put in place, in the form of a single rigid part. It is also to avoid the relative movements between, on the one hand, the body 1 and the ferrule 8 and, on the other hand, the coil 10, movements which are generated by vibrations of pumps and accessories surrounding the exchanger and which can cause friction which deteriorates the
éléments de l'échangeur.elements of the exchanger.
Elle est également de résoudre les problèmes liés à la corrosion, et ceci de deux manières D'une part, les écarteurs 17 a et 17 b créent des zones situées entre la virole 8 et le serpentin 10 et entre le corps 1 et le serpentin 10 qui sont, du point du vue de la corrosion, mortes D'autre part, en aménageant des espaces d'écoulement du fluide secondaire autour du serpentin 10, ils facilitent son écoulement et autorisent sa It is also to solve the problems linked to corrosion, and this in two ways. On the one hand, the spacers 17 a and 17 b create zones located between the shell 8 and the coil 10 and between the body 1 and the coil 10. which are, from the point of view of corrosion, dead On the other hand, by arranging spaces for the flow of the secondary fluid around the coil 10, they facilitate its flow and allow its
circulation sous des débits élevés. traffic under high flows.
On notera enfin que le fait que les écarteurs 17 a présentent des logements pour chaque spire du serpentin Finally, note that the fact that the spacers 17a have housings for each turn of the coil
permet de s'affranchir des écarts de diamètre d'enrou- allows you to get rid of variations in winding diameter
lement de chaque spire, ces écarts étant compensés par les différences d'épaisseur que prennent, au moment du montage de l'échangeur, les écarteurs 17 a entre leur face Lement of each turn, these differences being compensated by the differences in thickness that take, when mounting the exchanger, the spacers 17 a between their face
externe et leur logement.external and their housing.
L'eau à réchauffer s'écoule en montant dans le corps 1 (flèches A), d'une part, en hélice entre deux spires consécutives du serpentin 10 et, d'autre part, entre le serpentin 10 et le corps 1 ou la virole 8 Par contre, dans le serpentin 10, le fluide primaire s'écoule en descendant (flèches B), c'est-à-dire à contre-courant de l'eau du fluide secondaire. Le fluide primaire est, par exemple, un agent frigorifique issu d'une pompe à chaleur (non représentée) mais pourrait être aussi de la vapeur d'eau ou de l'eau chaude. The water to be heated flows upward into the body 1 (arrows A), on the one hand, in a helix between two consecutive turns of the coil 10 and, on the other hand, between the coil 10 and the body 1 or the shell 8 On the other hand, in the coil 10, the primary fluid flows downward (arrows B), that is to say against the current of the water of the secondary fluid. The primary fluid is, for example, a refrigerant from a heat pump (not shown) but could also be steam or hot water.
