L'échangeur de chaleur le plus largement utilisé est celui qui comporte un serpentin dans lequel s'écoule l'eau chaude, et qui est enveloppé extérieurement par l'eau du système de chauffage. Cependant, un échangeur de chaleur de ce type présente l'inconvénient important de n'être pas facilement accessible, de sorte que les dépôts calcaires restant dans le serpentin contenant l'eau chaude, qui est généralement The most widely used heat exchanger is that which has a coil in which hot water flows, and which is enveloped externally by water from the heating system. However, a heat exchanger of this type has the significant drawback of not being easily accessible, so that the lime deposits remaining in the coil containing the hot water, which is generally

quées de fabrication, ces joints augmentent le coût de l'appareil. These manufacturing seals increase the cost of the device.
La présente invention a expressément pour objet d'éliminer les inconvénients mentionnés ci-dessus, en fournissant donc un échangeur de chaleur qui permette d'accéder facilement à la surface d'échange de chaleur exposée à l'eau chaude et qui permette, par conséquent, d'éliminer complètement tous les dépôts calcaires de cette surface qui soit simple, compact et donc économique et qui assure également une sécurité constante de fonctionnement sans possibilité de transfert des fluides. Cet objet est sensiblement atteint par un tube de forme appro- priée qui, présentant un renflement torsadé en hélice et obtenu par moulage hydraulique, détermine respectivement au moyen d'un tube coaxial intérieur et d'un tube extérieur, également coaxial, les deux trajets hélicoïdaux d'écoulement utilisés pour le retour d'eau chaude du système de chauffage, qui s'élève dans le tube intérieur, et pour The present invention expressly aims to eliminate the drawbacks mentioned above, by therefore providing a heat exchanger which allows easy access to the heat exchange surface exposed to hot water and which therefore allows , to completely eliminate all lime deposits from this surface which is simple, compact and therefore economical and which also ensures constant operating safety without the possibility of transfer of fluids. This object is appreciably achieved by a tube of suitable shape which, having a bulge twisted in a helix and obtained by hydraulic molding, determines respectively by means of an internal coaxial tube and an external tube, also coaxial, the two paths. flow coils used for the return of hot water from the heating system, which rises in the inner tube, and for

De cette manière, l'échangeur de chaleur dans son ensemble est formé de trois tubes simplement emboftés coaxialement les uns dans les autres et formant un système qui est compact et facile à démonter et est donc d'accès aisé. En outre, toute possibilité de transfert de fluides est empêchée par un double joint torique étanche, prévu à chaque extrémité de l'échangeur de chaleur. L'économie du système est In this way, the heat exchanger as a whole is formed of three tubes simply fitted coaxially one inside the other and forming a system which is compact and easy to dismantle and is therefore easy to access. In addition, any possibility of transferring fluids is prevented by a tight double O-ring, provided at each end of the heat exchanger. The economy of the system is

tion; et - la figure 2 est une vue partiellement écorchée, à une échelle différente, des trois éléments séparés qui forment l'échangeur de chaleur. On se reportera maintenant aux figures. La référence numérique 1 désigne un tube présentant un renflement torsadé en hélice et obtenu par moulage hyraulique; ce tube est introduit coaxialement, de manière à se trouver intercalé entre un tube intérieur 2 et un tube extérieur 3. Ce tube torsadé comporte, à son extrémité de base 4, deux joints toriques 5 et 6 qui constituent des joints étanches entre le tion; and - Figure 2 is a partially cut away view, on a different scale, of the three separate elements which form the heat exchanger. We will now refer to the figures. The reference numeral 1 designates a tube having a bulge twisted in a helix and obtained by hydraulic molding; this tube is introduced coaxially, so as to be interposed between an inner tube 2 and an outer tube 3. This twisted tube has, at its base end 4, two O-rings 5 and 6 which constitute tight seals between the
tube 1 et le tube extérieur 3, et un-tube 7 de support qui est simple- tube 1 and the outer tube 3, and a support tube 7 which is simple-

Le même joint 11, pressé contre le rebord intérieur 12 formé à l'extrémité supérieure du tube extérieur 3, crée également un joint hermétique d'étanchéité entre le tube 1 et le cally, via the sealed O-rings 10 and 11, by a plug 9 venting. The same seal 11, pressed against the inner rim 12 formed at the upper end of the outer tube 3, also creates a hermetic seal between the tube 1 and the
tube 3. Enfin, le tube intérieur 2 se termine à sa base par un rétré- tube 3. Finally, the inner tube 2 ends at its base with a shrink
