Abstract
Description
La présente invention a pour objet un dispositif de chauffage d'un fluide par induction. The present invention relates to a device for heating a fluid by induction.
Ce dispositif est caractérise en ce qu'il comporte au moins un inducteur électro-magnétique associé à un circuit magnétique fermé qui est creux et relié à une conduite d'arrivée de fluide et à une conduite de départ de ce fluide. This device is characterized in that it comprises at least one electromagnetic inductor associated with a closed magnetic circuit which is hollow and connected to a fluid inlet pipe and to a pipe for the start of this fluid.
Lorsque l'inducteur est sous tension, les courants de Foucault induits dans le circuit magnétique entraient le chauffage de celui-ci qui, à son tour, chauffe le fluide le traversant. When the inductor is energized, the eddy currents induced in the magnetic circuit enter the heating thereof which, in turn, heats the fluid passing through it.
Le circuit magnétique étant fermé, l'énergie réactive est réduite à une valeur minimale. With the magnetic circuit closed, the reactive energy is reduced to a minimum value.
Le dispositif selon l'invention permet d'assurer un chauffage pratiquement instantané. I1 peut être utilisé seul ou en association avec un réservoir et former ainsi une chaudière. The device according to the invention allows practically instantaneous heating. It can be used alone or in combination with a tank and thus form a boiler.
On a décrit ci-après, à titre d'exemple non limitatif, un mode de réalisation du dispositif de chauffage selon l'invention, avec référence au dessin annexé dans lequel
La Figure 1 est un schéma du dispositif de chauffage;
La Figure 2 montre un mode de montage de ce dispositif.An embodiment of the heating device according to the invention has been described below, by way of non-limiting example, with reference to the appended drawing in which
Figure 1 is a diagram of the heater;
Figure 2 shows an assembly method of this device.
Tel qu'il est représenté au dessin, le dispositif de chauffage selon l'invention comprend un circuit magnétique fermé constitué de trois tubes la, lb et lc reliés en parallèles à chacune de leurs extrémités par deux conduits 2a et 2b, eux-mêmes reliés respectivement à un conduit d'arrivée de fluide 3 et à un condùit de départ de fluide 4. As shown in the drawing, the heating device according to the invention comprises a closed magnetic circuit consisting of three tubes la, lb and lc connected in parallel to each of their ends by two conduits 2a and 2b, themselves connected respectively to a fluid inlet duct 3 and to a fluid inlet duct 4.
Chacun des tubes la, lb et lc est entouré par un enroulement inducteur 5, avec interposition d'un manchon de protection thermique 6. Les enroulements 5 sont reliés respectivement à deux phases d'une alimentation triphasée. Each of the tubes 1a, 1b and 1c is surrounded by an inductor winding 5, with the interposition of a thermal protection sleeve 6. The windings 5 are connected respectively to two phases of a three-phase supply.
A la Figure 2, le circuit magnétique avec ses inducteurs est désigné d'une façon générale par la référence 7. Les enroulements 5 sont connectés à une source d'alimentation 8 par l'intermédiaire d'un interrupteur manuel 9 et d'un interrupteur piloté 10 à thyristors. In Figure 2, the magnetic circuit with its inductors is generally designated by the reference 7. The windings 5 are connected to a power source 8 via a manual switch 9 and a switch piloted 10 thyristors.
Le conduit de départ 4 est muni d'un capteur de température 11 qui commande l'interrupteur 10. Sur le conduit d'alimentation 3 est interposée une vanne électrique 12 commandée par un contrôleur de débit 13 placé sur le conduit 4. The outlet conduit 4 is provided with a temperature sensor 11 which controls the switch 10. On the supply conduit 3 is interposed an electric valve 12 controlled by a flow controller 13 placed on the conduit 4.
Lorsque les interrupteurs 9 et 10 sont fermés, le courant indUit dans le circuit magnétique le chauffe; mais ce circuit forme- échangeur avec le fluide qu'il contient et chauffe à son tour ce fluide. When the switches 9 and 10 are closed, the current indUit in the magnetic circuit heats it; but this circuit-exchanger with the fluid it contains and in turn heats this fluid.
Si la température du fluide devient trop élevée, le capteur 11 provoque l'ouverture de l'interrupteur 10 et le referme lorsque la température s'est suffisamment abaissée. Si le débit de fluide chauffé devient trop important, ce qui empêche le fluide d'être suffisamment chauffé, le contrôleur de débit 13 agit sur la vanne 12 pour réguler ce débit. If the temperature of the fluid becomes too high, the sensor 11 causes the switch 10 to open and to close again when the temperature has dropped sufficiently. If the flow of heated fluid becomes too high, which prevents the fluid from being sufficiently heated, the flow controller 13 acts on the valve 12 to regulate this flow.
Les conduits 3 et 4 pourraient être reliés à un même réservoir par l'intermédiaire d'une pompe de circulation. L'ensemble constituerait ainsi une chaudière qui pourrait être utilisée aussi bien pour le chauffage industriel que dans une installation de chauffage central. The conduits 3 and 4 could be connected to the same tank by means of a circulation pump. The assembly would thus constitute a boiler which could be used both for industrial heating and in a central heating installation.
Il va de soi que la présente invention ne doit pas être considérée comme limitée au mode de réalisation décrit et représenté, mais en couvre, au contraire, toutes les variantes. It goes without saying that the present invention should not be considered as limited to the embodiment described and shown, but on the contrary covers all variants thereof.
