Vertical hot water tubes (50), in modular cases (10), are connected via short horizontal pipe sections (101, 102) to corresponding parts of adjacent modules. Heat dissipation is aided by vertical fins and face-plates (2). For the proposed application, an opening (5) is made in the module base, normally closed, allowing an elongated heat storage element (20), also of pressure die-cast alloy, closely fitting the tube interior, to be slid in from below. The element embodies a heating resistance, bent into a hair-pin, with terminal wiring (6), protruding at the base, connected to bus-wires running within a protective trough (60) along to a mains-connected regulating unit (30).

Description

La présente invention concerne un radiateur électrique à accumulation d'énergie, de structure modulaire. Elle vise également un procédé pour sa réalisation.The present invention relates to a radiator electric energy storage, structural modular. It also relates to a process for its production.

La recherche d'un confort de chauffage supérieur à celui obtenu avec des convecteurs électriques et l'objectif de réaliser des économies d'énergie contribuent au développement actuel des radiateurs électriques à accumulation réalisés à partir d'alliage léger moulé sous pression, notamment d'alliage d'aluminium, qui peuvent être avantageusement installés en des emplacements prévus pour des radiateurs de chauffage central. Le FR 2678717 divulgue ainsi un radiateur électrique à accumulation constitué d'éléments modulaires comportant dans une partie centrale des briques réfractaires équipées d'une résistance électrique interne et contenues dans une enveloppe tubulaire à section rectangulaire. Du fait de la différence entre les coefficients de dilatation respectifs de l'alliage moulé et les briques réfractaires, celles-ci sont soumises à des contraintes mécaniques significatives qui conduisent à la génération de bruits acoustique intempestifs et désagréables et à un effritement à terme des briques réfractaires. En outre, on observe des problèmes de non uniformité des températures sur l'ensemble du radiateur du fait de la relative concentration des éléments générateurs de chaleur.The search for heating comfort greater than that obtained with electric convectors and the goal of saving energy contribute to the current development of radiators electric accumulators made from alloy lightweight die-cast, especially of alloy aluminum, which can be advantageously installed in places provided for radiators of central heating. FR 2678717 thus discloses a electric storage heater modular elements comprising in one part central refractory bricks equipped with a internal electrical resistance and contained in a tubular casing with rectangular section. Because of the difference between the expansion coefficients of the molded alloy and the bricks refractory, these are subject to constraints significant mechanics which lead to the generation of unwanted acoustic noise and unpleasant and eventually crumbling bricks refractory. In addition, there are problems of non uniformity of temperatures throughout the radiator due to the relative concentration of elements heat generators.

Par ailleurs, le FR 2716255 divulgue un radiateur électrique à accumulation constitué d'éléments modulaires et comportant un corps de chauffe unique. Ce radiateur comporte un évidement permettant de loger une brique réfractaire unique équipée d'une résistance électrique interne et logée dans les éléments modulaires. C'est la longueur du corps de chauffe constitué par la brique réfractaire unique qui conditionne la longueur du radiateur et le nombre d'éléments modulaires. Ce mode de réalisation restreint singulièrement le caractère modulaire d'un tel radiateur à accumulation, puisqu'on ne peut pas dans ce mode prévoir un nombre d'éléments modulaires quelconque. Par ailleurs, ce mode de réalisation suppose, soit de concevoir un moule spécifique incluant la réalisation d'une cavité interne globale, soit d'usiner dans des éléments modulaires existants une cavité interne apte à recevoir le corps de chauffe unique.In addition, FR 2716255 discloses a radiator electric storage system made up of elements modular and with a single heating body. This radiator has a recess for housing a unique refractory brick with resistance internal electric and housed in the elements modular. This is the length of the heater constituted by the unique refractory brick which determines the length of the radiator and the number modular elements. This restricted embodiment singularly the modular nature of such storage heater, since you cannot in this mode provide a number of modular elements any. Furthermore, this embodiment supposes either to design a specific mold including the creation of a global internal cavity, to machine into existing modular elements a internal cavity capable of receiving the heating body unique.

Le but de la présente invention est de remédier à ces inconvénients en proposant un radiateur électrique qui présente les performances thermiques normalement attendues d'un système à accumulation, tout en offrant une meilleure répartition spatiale de la chaleur que ce qu'on peut obtenir avec les radiateurs de l'art antérieur, et en étant de réalisation plus simple que les radiateurs à corps de chauffe unique.The object of the present invention is to remedy these disadvantages by proposing an electric heater which presents the thermal performances normally expected from an accumulation system, while providing better spatial distribution of heat than what that can be obtained with art radiators earlier, and being of simpler realization than radiators with a single heating body.

Ceci est obtenu avec un radiateur à accumulation comprenant un assemblage d'éléments modulaires en alliage léger, chaque élément modulaire étant de forme sensiblement allongée et comprenant une pièce centrale creuse comportant une cavité interne débouchant par une ouverture sur une extrémité inférieure dudit élément modulaire, et des moyens résistifs pour convertir de l'énergie électrique en énergie thermique accumulée au sein desdits éléments modulaires.This is achieved with a storage heater comprising an assembly of modular elements in light alloy, each modular element being shaped substantially elongated and comprising a central part hollow comprising an internal cavity opening out through a opening on a lower end of said element modular, and resistive means for converting electrical energy as thermal energy accumulated at within said modular elements.

Suivant l'invention, les moyens résistifs de conversion d'énergie sont inclus dans des corps de chauffe modulaires en alliage léger insérés dans les cavités internes des éléments modulaires via leurs ouvertures inférieures respectives.According to the invention, the resistive means of energy conversion are included in bodies of modular light alloy heaters inserted in the internal cavities of the modular elements via their Respective lower openings.

Le mérite de cette invention réside notamment dans le fait que l'on tire parti de l'existence de cavités internes dans les éléments modulaires de radiateurs en alliage léger réalisés initialement pour des systèmes de chauffage central. Ces radiateurs présentent usuellement des cavités verticales permettant la circulation d'eau chaude ou de vapeur entre un point d'entrée haut et un point de sortie bas. Une modification des éléments modulaires standards constituant ces radiateurs est en outre économiquement viable puisqu'elle évite les opérations très coûteuse de conception globale d'un nouveau modèle.The merit of this invention lies in particular in the fact that we take advantage of the existence of cavities internal in the modular elements of radiators in light alloy initially produced for systems central heating. These radiators have usually vertical cavities allowing the circulation of hot water or steam between a point high entry point and low exit point. A modification of standard modular elements constituting these radiators is further economically viable since it avoids very costly operations overall design of a new model.

Pour un radiateur selon l'invention, les corps de chauffe modulaires présentent de préférence un contour extérieur conçu pour épouser sensiblement le contour intérieur des cavités internes des éléments modulaires. Les corps de chauffe et les éléments modulaires étant de préférence réalisés à partir du même alliage, on évite ainsi les délicats problèmes de déformation et de bruit acoustique induits par les différences de coefficient de dilatation des différents matériaux mis en oeuvre.For a radiator according to the invention, the bodies of modular heaters preferably have an outline exterior designed to closely follow the outline interior of the internal cavities of the modular elements. The heating elements and the modular elements being preferably made from the same alloy, thus avoids the delicate problems of deformation and acoustic noise induced by differences in coefficient of expansion of the different materials used in action.

Un radiateur électrique selon l'invention comprend en outre des moyens pour connecter électriquement les corps de chauffe modulaires à des moyens de fourniture et de régulation d'énergie électrique disposés à proximité immédiate des ouvertures inférieures respectives des éléments modulaires recevant ces corps de chauffe modulaires. On met ainsi avantageusement à profit l'existence d'ouvertures inférieures pour les cavités internes de chaque élément modulaire, non seulement pour permettre l'insertion des corps de chauffe mais également pour assurer la connexion électrique de ces corps de chauffe. Lorsqu'il s'agit d'adapter un radiateur conçu initialement pour une installation de chauffage central et dans lequel les ouvertures inférieures sont normalement obturées par des bouchons, on peut prévoir de sectionner ces bouchons pour avoir accès aux cavités internes dans lesquelles les corps de chauffe seront insérés. An electric heater according to the invention comprises furthermore means for electrically connecting the modular heaters to supply means and electric power regulation arranged to close proximity to lower openings respective modular elements receiving these bodies modular heaters. This advantageously puts profit the existence of lower openings for internal cavities of each modular element, not only to allow the insertion of the bodies of heats but also to ensure the connection electric of these heaters. As it's about to adapt a radiator originally designed for a central heating installation and in which the lower openings are normally closed by plugs, we can plan to cut these plugs to gain access to the internal cavities in which the heaters will be inserted.

Les éléments modulaires et les corps de chauffe des radiateurs selon l'invention sont de préférence réalisés à partir d'alliages d'aluminium moulés sous pression.The modular elements and the heating bodies of the radiators according to the invention are preferably made from die-cast aluminum alloys pressure.

On va maintenant décrire un exemple de réalisation d'un radiateur selon l'invention, en référence aux figures précitées.We will now describe an example of an embodiment of a radiator according to the invention, with reference to aforementioned figures.

Un radiateur électrique à accumulation 1 selon l'invention comprend un assemblage d'éléments modulaires 10 réalisés en alliage d'aluminium moulé sous pression selon des techniques connues et largement mises en oeuvre pour la réalisation de radiateurs pour chauffage central. Ces éléments modulaires 10 sont normalement solidarisés selon une technique dite de "niplage" consistant à visser entre eux des tronçons de tube respectivement supérieurs et inférieurs 101, 102 inclus dans ces éléments modulaires 10. Chaque élément modulaire 10 comprend une face avant 2, une face arrière 1, et entre ces deux faces une pièce creuse centrale 8 de forme sensiblement allongée s'étendant sur la majeure partie de la hauteur du radiateur et présentant une cavité interne 50 débouchant dans sa partie supérieure dans le tronçon de tube supérieur, et dans sa partie inférieure débouchant dans le tronçon de tube inférieur et présentant une ouverture inférieure 5. Chaque cavité interne 50 reçoit un corps de chauffe modulaire 20 qui est inséré par l'ouverture inférieure 5. Ce corps de chauffe 20 présente un contour extérieur conçu pour être parfaitement ajusté à l'intérieur de la cavité interne 50, assurant ainsi une parfaite conduction thermique entre les corps de chauffe 20 et les pièces centrales creuses 8 du radiateur 1. Chaque élément modulaire 10 est normalement doté d'ailettes 7 disposées entre les faces avant et arrière 2, 3 qui sont reliées à la pièce creuse centrale 8 respectivement par des entretoises 52, 51. Les ouvertures inférieures 5 des différents éléments modulaires 10 communiquent avec une gouttière de connexion 60 disposée contre la partie inférieure du radiateur 1 et prévue pour recevoir les câbles d'alimentation 6 respectifs de chaque corps de chauffe 20 passant à travers les ouvertures inférieures 5. Ces câbles d'alimentation 6, reliés aux résistances internes 21 des corps de chauffe 20 au moyen de connecteurs 23, peuvent par exemple être reliés en parallèle à un bus commun d'alimentation 22 en sortie d'une unité d'alimentation et de régulation 30 connectée au secteur et qui peut être réalisée selon les techniques connues et utilisées classiquement dans le domaine de la régulation thermique appliquée aux radiateurs électriques à accumulation.An electric storage heater 1 according to the invention comprises an assembly of elements modular 10 made of cast aluminum alloy under pressure according to known techniques and widely implemented for the production of radiators for central heating. These modular elements 10 are normally joined together using a technique called "niplage" consisting in screwing between them sections of respectively upper and lower tube 101, 102 included in these modular elements 10. Each element modular 10 includes a front face 2, a face rear 1, and between these two faces a hollow part central 8 of substantially elongated shape extending over most of the height of the radiator and having an internal cavity 50 opening into its upper part in the upper tube section, and in its lower part opening into the section of lower tube and having a lower opening 5. Each internal cavity 50 receives a heating body modular 20 which is inserted through the lower opening 5. This heating body 20 has an outer contour designed to fit snugly inside the internal cavity 50, thus ensuring perfect thermal conduction between the heating bodies 20 and the hollow central parts 8 of the radiator 1. Each modular element 10 is normally fitted with fins 7 arranged between the front and rear faces 2, 3 which are connected to the central hollow part 8 respectively by spacers 52, 51. The lower openings 5 of the different elements modular 10 communicate with a gutter of connection 60 arranged against the lower part of the radiator 1 and designed to receive cables respective 6 supply of each heating body 20 passing through the lower openings 5. These power cables 6, connected to resistors internal 21 of the heating bodies 20 by means of connectors 23, can for example be connected in parallel to a common supply bus 22 at the output a power and regulation unit 30 connected to the mains and which can be carried out according to the techniques known and conventionally used in the field of thermal regulation applied to electric storage heaters.

Les radiateurs à accumulation selon l'invention peuvent avantageusement être fabriqués à partir d'éléments modulaires en alliage d'aluminium moulé sous pression conçus initialement pour des radiateurs à eau, en évitant ainsi d'avoir à réaliser des moules spécifiques, ce qui permet une réduction significative des coûts de réalisation. En effet, un radiateur 1 selon l'invention peut être fabriqué selon les étapes suivantes:

  • on réalise, par moulage sous pression, des éléments modulaires 10 comportant chacun une pièce centrale creuse 8 dotée d'une ouverture inférieure,
  • on réalise, par moulage sous pression, des corps de chauffe 20 contenant une résistance chauffante 21 blindée ayant par exemple la forme d'une épingle,
  • on insère dans les cavités internes 50 des éléments modulaires 10 les corps de chauffe 20,
  • on réalise les connexions des éléments modulaires 10 avec une unité d'alimentation et de régulation 30,
  • on fixe une gouttière de connexion 60 de longueur adaptée sur la partie inférieure du radiateur, pour masquer et protéger les connexions entre les corps de chauffe 20 et l'unité d'alimentation et de régulation 30.
The storage radiators according to the invention can advantageously be manufactured from modular elements made of die-cast aluminum alloy initially designed for water radiators, thus avoiding having to produce specific molds, which allows a significant reduction in production costs. Indeed, a radiator 1 according to the invention can be manufactured according to the following steps:
  • modular elements 10 are produced by pressure molding each comprising a hollow central part 8 provided with a lower opening,
  • heating bodies 20 containing a shielded heating resistor 21, for example in the form of a pin, are produced by pressure molding,
  • the heating elements 20 are inserted into the internal cavities 50 of the modular elements 10,
  • the connections of the modular elements 10 are made with a supply and regulation unit 30,
  • a connection gutter 60 of suitable length is fixed on the lower part of the radiator, in order to mask and protect the connections between the heating bodies 20 and the supply and regulation unit 30.

Mais ce mode de réalisation particulièrement économique n'est pas limitatif et on peut fort bien concevoir spécifiquement des éléments modulaires adaptés pour réaliser un radiateur à accumulation selon l'invention.But this particularly embodiment economic is not limiting and we can very well specifically design modular elements suitable for producing a storage heater according to the invention.

Bien sûr, l'invention n'est pas limitée aux exemples qui viennent d'être décrits et de nombreux aménagements peuvent être apportés à ces exemples sans sortir du cadre de l'invention. Ainsi, les cavités internes recevant les corps de chauffe peuvent être de forme quelconque et on peut envisager bien d'autres modes de connexion électrique que celui qui vient d'être décrit. Par ailleurs, l'invention n'est pas limitée à des radiateurs réalisés à partir d'alliages d'aluminium moulés sous pression, mais peut être mise en oeuvre avec d'autres techniques de fabrication. De plus, on peut prévoir de loger l'unité de contrôle et de régulation au sein d'une cavité ménagée dans l'un des éléments modulaires d'un radiateur, ou selon toute autre disposition, sans sortir du cadre de la présente invention.Of course, the invention is not limited to examples just described and many adjustments can be made to these examples without depart from the scope of the invention. So the cavities internal receiving heaters can be any shape and we can consider many others modes of electrical connection than whoever comes to be described. Furthermore, the invention is not limited to radiators made from alloys die-cast aluminum but can be put implemented with other manufacturing techniques. Of more, we can plan to house the control unit and regulation within a cavity formed in one modular elements of a radiator, or whichever other provision, without departing from the scope of this invention.
