Description

La présente invention concerne un appareil de chauffage de type radiateur électrique destiné à être raccordé électriquement à une source d'alimentation en énergie électrique, l'appareil comprenant un boitier constitué au moins en partie par une carcasse métallique et au moins un corps de chauffe rayonnant implanté dans la carcasse métallique.The present invention relates to a heating device of the electric radiator type intended to be electrically connected to a power supply source of electrical energy, the device comprising a box formed at least in part by a metal frame and at least one radiating heating body. implanted in the metal frame.

L'invention porte aussi sur une installation électrique comprenant au moins un tel appareil de chauffage dont le corps de chauffe rayonnant est relié électriquement à une source de tension.The invention also relates to an electrical installation comprising at least one such heating device, the radiating heating body of which is electrically connected to a voltage source.

Un appareil de chauffage du type décrit ci-avant fonctionne sur le principe de rayonnement et ne doit pas être confondu avec les appareils de chauffage qui fonctionnent sur le principe de convection.A heater of the type described above operates on the principle of radiation and should not be confused with heaters which operate on the principle of convection.

Dans le domaine des appareils de chauffage de type rayonnant, il existe une première catégorie où le corps de chauffe rayonnant rayonne directement vers l'extérieur du boitier le flux de calories qu'il génère.In the field of radiant type heating devices, there is a first category where the radiant heating body radiates directly to the outside of the box the flow of calories that it generates.

Il existe une seconde catégorie où le corps de chauffe rayonnant est dit primaire, car son rôle est de chauffer un corps rayonnant secondaire qui lui fait face. Dans cette organisation, c'est le corps rayonnant secondaire qui rayonne les calories vers l'extérieur du boitier. Un avantage de cette organisation est de privilégier des propriétés d'inertie thermique élevée pour le corps de chauffe rayonnant primaire et de privilégier des propriétés de forte émissivité pour le corps rayonnant secondaire.There is a second category where the radiating heating body is said to be primary, because its role is to heat a secondary radiating body which faces it. In this organization, it is the secondary radiant body which radiates the calories to the outside of the box. One advantage of this organization is to favor high thermal inertia properties for the primary radiating heating body and to favor high emissivity properties for the secondary radiating body.

Classiquement, un appareil de chauffage est conçu pour ne fonctionner qu'en association avec une sorte de source d'alimentation en énergie électrique prédéterminée. Généralement, un appareil de chauffage donné est conçu pour uniquement fonctionner en association avec une source de tension électrique alternative.Conventionally, a heater is designed to operate only in conjunction with some kind of predetermined electrical power supply source. Generally, a given heater is designed to operate only in conjunction with an alternating electrical voltage source.

Or, la tendance actuelle prévoit que les installations électriques des habitations reposent sur une diversité de sources d'alimentation électrique, typiquement mêlant des sources de tension continue et des sources de tension alternative, notamment pour inclure une production locale d'électricité. Or, dans cette organisation, les appareils de chauffage connus ne peuvent alors être utilisés qu'en association avec une partie seulement des sources de courant disponibles, ce qui est extrêmement contraignant et limitant.However, the current trend provides that the electrical installations of homes are based on a variety of electrical power sources, typically combining direct voltage sources and alternating voltage sources, in particular to include local production of electricity. However, in this organization, the known heating devices cannot then be used that in association with only part of the available current sources, which is extremely restrictive and limiting.

Par ailleurs, il est difficile de pouvoir accepter une diversité de types de sources d'alimentation électrique tout en préservant une puissance de chauffe constante, ce qui serait gage de confort.Furthermore, it is difficult to be able to accept a variety of types of electric power supply sources while preserving a constant heating power, which would be a guarantee of comfort.

L'appareil de chauffage 10 comprend aussi au moins un premier élément blindé 15 constitué par un premier type de corps résistif apte à générer de la chaleur lorsqu'il est alimenté par un courant électrique alternatif.The heater 10 also comprises at least a first shielded element 15 constituted by a first type of resistive body capable of generating heat when it is supplied by an alternating electric current.

En complément dudit au moins un premier élément blindé 15, l'appareil de chauffage 10 comprend également au moins un deuxième élément blindé 16 constitué par un deuxième type de corps résistif apte à générer de la chaleur lorsqu'il est alimenté par un courant électrique continu.In addition to said at least one first shielded element 15, the heating apparatus 10 also comprises at least one second shielded element 16 constituted by a second type of resistive body capable of generating heat when it is supplied by a direct electric current. .

Il est donc bien compris que le nombre de premier élément blindé 15 peut être supérieur ou égal à 1 et chacun d'eux délivre de la chaleur lorsqu'il est alimenté par une source de courant électrique alternatif. Le nombre de deuxième élément blindé 16 est également supérieur ou égal à 1 et, à l'inverse du premier élément blindé 15, chacun d'eux délivre de la chaleur lorsqu'il est alimenté par une source de courant électrique continu.It is therefore well understood that the number of first shielded element 15 may be greater than or equal to 1 and each of them delivers heat when it is supplied by an alternating electric current source. The number of second shielded element 16 is also greater than or equal to 1 and, unlike the first shielded element 15, each of them delivers heat when supplied by a source of direct electric current.

La présence combinée d'au moins un premier élément blindé 15 constitué par un corps résistif apte à générer de la chaleur lorsqu'il est alimenté par un courant électrique alternatif et d'au moins un deuxième élément blindé 16 constitué par un corps résistif apte à générer de la chaleur lorsqu'il est alimenté par un courant électrique continu permet de garantir une puissance de chauffe sensiblement constante et rend l'appareil de chauffage 10 exploitable sous une source de courant alternatif et/ou sous une source de courant continu. En outre, du fait de la possibilité d'utiliser au moins deux sources d'alimentation de manière simultanée, l'appareil de chauffage 10 présente avantageusement une montée en température potentielle très élevée pour son corps de chauffe rayonnant 12.The combined presence of at least a first shielded element 15 constituted by a resistive body capable of generating heat when it is supplied by an alternating electric current and of at least a second shielded element 16 constituted by a resistive body capable of generating heat when supplied by a direct electric current makes it possible to guarantee a substantially constant heating power and makes the heater 10 operable under an alternating current source and / or under a direct current source. In addition, due to the possibility of using at least two power sources simultaneously, the heater 10 advantageously has a very high potential temperature rise for its radiating heater body 12.

Au sein de l'installation électrique maintenant, laquelle comprend au moins un tel appareil de chauffage 10, chaque premier élément blindé 15 est relié électriquement à une première source de tension alternative de sorte à être alimenté par un courant électrique alternatif. Alternativement ou de manière combinée, chaque deuxième élément blindé 16 est relié électriquement à une deuxième source de tension continue de sorte à être alimenté par un courant électrique continu.Within the electrical installation now, which comprises at least one such heater 10, each first shielded element 15 is electrically connected to a first source of alternating voltage so as to be supplied by an alternating electric current. Alternatively or in combination, each second shielded element 16 is electrically connected to a second direct voltage source so as to be supplied with direct electric current.

Selon un mode de réalisation particulier, la première source de tension alternative alimente chaque premier élément blindé 15 à un premier niveau de tension et la deuxième source de tension continue alimente chaque deuxième élément blindé 16 à un deuxième niveau de tension strictement différent du premier niveau de tension. A titre d'exemple, le premier niveau de tension correspond au niveau de tension du réseau électrique local, notamment sensiblement égal à 220V en Europe, et le deuxième niveau de tension est compris dans une plage allant de 20V à 60V, notamment sensiblement égal à 50V.According to a particular embodiment, the first alternating voltage source supplies each first shielded element 15 at a first voltage level and the second direct voltage source supplies each second shielded element 16 at a second voltage level strictly different from the first voltage level. voltage. By way of example, the first voltage level corresponds to the voltage level of the local electrical network, in particular substantially equal to 220V in Europe, and the second voltage level is within a range from 20V to 60V, in particular substantially equal to 50V.

A titre d'exemple, chaque élément blindé 15, 16 constitué par un corps résistif comprend un fil résistif placé dans une gaine métallique tubulaire remplie d'un isolant pulvérulent tel que de la magnésie électro-fondue. Le laminage de la gaine assure le compactage de l'isolant, nécessaire pour obtenir une bonne conductibilité thermique et une excellente tenue mécanique et diélectrique. Les extrémités de la gaine sont rendues étanches, par exemple par utilisation d'une résine telle que du silicone, de l'époxy ou du polyuréthane, et finalisées par un bouchon, par exemple en céramique.By way of example, each shielded element 15, 16 constituted by a resistive body comprises a resistive wire placed in a tubular metal sheath filled with a pulverulent insulator such as electro-molten magnesia. The lamination of the sheath ensures the compaction of the insulation, necessary to obtain good thermal conductivity and excellent mechanical and dielectric strength. The ends of the sheath are made waterproof, for example by using a resin such as silicone, epoxy or polyurethane, and finalized by a plug, for example ceramic.

De manière générale, chaque premier élément blindé 15 est noyé dans la matière 17 dudit au moins un corps de chauffe rayonnant 12. De manière similaire, chaque deuxième élément blindé 16 est noyé dans la matière 17 dudit au moins un corps de chauffe rayonnant 12. Les Figures 2 à 4 représentent trois modes de réalisation possibles de ces principes généraux.In general, each first shielded element 15 is embedded in the material 17 of said at least one radiating heating body 12. Similarly, each second shielded element 16 is embedded in the material 17 of said at least one radiating heating body 12. The Figures 2 to 4 represent three possible embodiments of these general principles.

Lorsque au moins un premier élément blindé 15 est alimenté par un courant alternatif et/ou lorsque au moins un deuxième élément blindé 16 est alimenté par un courant continu, le corps de chauffe rayonnant 12 dégage un flux de calories noté F1.When at least a first shielded element 15 is supplied by an alternating current and / or when at least a second shielded element 16 is supplied by a direct current, the radiating heating body 12 gives off a flow of calories denoted F1.

Dans la variante de la Figure 1 qui n'est absolument pas limitative quant au domaine d'application visé par l'invention, le corps de chauffe rayonnant 12 est unique et constitue un corps de chauffe rayonnant dit « primaire » disposé en regard d'un corps rayonnant secondaire 13 agencé de sorte à délivrer un flux F2 de calories sortant hors de la carcasse métallique 11. Le corps de chauffe rayonnant 12 intègre au moins un premier élément blindé 15 apte à fonctionner sous une alimentation en courant alternatif et au moins un deuxième élément blindé 16 apte à fonctionner sous une alimentation en courant continu.In the variant of Figure 1 which is absolutely not limiting as to the field of application targeted by the invention, the radiating heating body 12 is unique and constitutes a so-called "primary" radiating heating body arranged opposite a secondary radiating body 13 arranged in so as to deliver a flow F2 of calories coming out of the metal frame 11. The radiating heating body 12 incorporates at least a first shielded element 15 able to operate under an alternating current supply and at least one second shielded element 16 able to operate under a DC power supply.

Le corps rayonnant secondaire 13 présente une surface tournée vers le corps de chauffe rayonnant 12 et recouverte au moins partiellement par un film absorbant 14 apte à absorber tout ou partie du flux F1 de calories généré par le corps de chauffe rayonnant 12 lorsque le premier élément blindé 15 est alimenté en courant électrique alternatif et/ou le deuxième élément blindé 16 est alimenté en courant électrique continu.The secondary radiating body 13 has a surface facing the radiating heating body 12 and covered at least partially by an absorbing film 14 capable of absorbing all or part of the flow F1 of calories generated by the radiating heating body 12 when the first shielded element 15 is supplied with alternating electric current and / or the second shielded element 16 is supplied with direct electric current.

Dans cette organisation, le corps rayonnant secondaire 13 est configuré de sorte à privilégier des propriétés de forte émissivité vers l'extérieur de la carcasse métallique 11. La présence du corps rayonnant secondaire 13 permet d'abaisser la température fournie par les premier et deuxième éléments blindés 15, 16 et de stabiliser la température de la surface de l'appareil 10 en contact avec l'air.In this organization, the secondary radiating body 13 is configured so as to favor properties of high emissivity towards the outside of the metal carcass 11. The presence of the secondary radiating body 13 makes it possible to lower the temperature. temperature supplied by the first and second shielded elements 15, 16 and to stabilize the temperature of the surface of the apparatus 10 in contact with the air.

A titre d'exemple, un tel corps rayonnant secondaire 13 peut comprendre tout ou partie des éléments suivants, isolément ou en combinaison :

  • du verre trempé de type aluminosilicate, borosilicate ou alumino-boro-silicate,
  • un polymère transparent et résistant à la température, comme par exemple du polyacrylate,
  • une structure sandwich comportant une céramique avec une bonne émissivité et une bonne transmission dans l'infrarouge lointain (une longueur d'onde comprise entre 2 et 10 µm).
By way of example, such a secondary radiating body 13 can comprise all or part of the following elements, individually or in combination:
  • tempered glass of the aluminosilicate, borosilicate or alumino-boro-silicate type,
  • a transparent and temperature-resistant polymer, such as polyacrylate, for example,
  • a sandwich structure comprising a ceramic with good emissivity and good transmission in the far infrared (a wavelength of between 2 and 10 μm).

Le corps rayonnant secondaire 13 pourra avantageusement présenter de bonnes propriétés de transmission dans l'infrarouge lointain (une longueur d'onde comprise entre 2 et 10 µm)afin de maximiser la quantité de rayonnement émis par le corps de chauffe rayonnant 12.The secondary radiating body 13 may advantageously exhibit good transmission properties in the far infrared (a wavelength of between 2 and 10 μm) in order to maximize the quantity of radiation emitted by the radiating heating body 12.

Par contre, dans l'organisation de la Figure 1, la matière 17 du corps de chauffe rayonnant 12 dans laquelle chaque premier élément blindé 15 et chaque deuxième élément blindé 16 sont noyés présente des propriétés d'inertie thermique faible et une très bonne conductivité thermique. A titre d'exemple, cette matière est un alliage d'aluminium ou un alliage de cuivre.On the other hand, in the organization of the Figure 1 , the material 17 of the radiating heating body 12 in which each first shielded element 15 and each second shielded element 16 are embedded has low thermal inertia properties and very good thermal conductivity. For example, this material is an aluminum alloy or a copper alloy.

Il est rappelé que dans l'organisation exploitant la présence d'un corps rayonnant secondaire 13, il est possible de remplacer le corps de chauffe rayonnant 12 unique et d'un seul tenant par au moins deux corps de chauffe rayonnant distincts 12a, 12b et séparés, par exemple en prévoyant que l'un de ces deux corps de chauffe rayonnant intègre au moins un premier élément blindé 15 et que l'autre de ces deux corps de chauffe rayonnant intègre au moins un deuxième élément blindé 16.It is recalled that in the organization exploiting the presence of a secondary radiating body 13, it is possible to replace the radiating heating body 12, which is unique and in one piece by at least two separate radiating heating bodies 12a, 12b and separated, for example by providing that one of these two radiating heating bodies integrates at least a first shielded element 15 and that the other of these two radiating heating bodies incorporates at least one second shielded element 16.

Dans une variante non représentée, il reste même envisageable que l'appareil de chauffage 10 n'exploite pas de corps rayonnant secondaire 13. Dans ce cas, le flux F1de calories générées par ledit au moins un corps de chauffe rayonnant 12 lorsque le premier élément blindé 15 est alimenté en courant électrique alternatif et/ou le deuxième élément blindé 16 est alimenté en courant électrique continu est directement transmis vers l'extérieur de la carcasse métallique 11 à travers un garde-corps adapté.In a variant not shown, it can even be envisaged that the heating device 10 does not use a secondary radiating body 13. In this case, the flow F1 of calories generated by said at least one radiating heating body 12 when the first element armored 15 is supplied with alternating electric current and / or the second armored element 16 is supplied with direct electric current is transmitted directly to the outside of the metal frame 11 through a suitable guardrail.

Dans les versions des Figures 2 et 3, l'appareil de chauffage 10 comprend un unique corps de chauffe rayonnant 12 d'un seul tenant implanté dans la carcasse métallique 11 et incluant ledit au moins un premier élément blindé 15 et ledit au moins un deuxième élément blindé 16, noyés dans sa matière 17.In the versions of Figures 2 and 3 , the heating device 10 comprises a single radiating heating body 12 in one piece implanted in the carcass metallic 11 and including said at least one first shielded element 15 and said at least one second shielded element 16, embedded in its material 17.

A l'inverse, dans la version de la Figure 4, l'appareil de chauffage 10 comprend un premier corps de chauffe rayonnant 12a et un deuxième corps de chauffe rayonnant 12b distinct du premier corps de chauffe rayonnant 12a. Ledit au moins un premier élément blindé 15 est noyé dans la matière 17a du premier corps de chauffe rayonnant 12a tandis que ledit au moins un deuxième élément blindé 16 est noyé dans la matière 17b du deuxième corps de chauffe rayonnant 12b. Les matières 17a et 17b peuvent être identiques ou non. Les corps de chauffe rayonnant 12a et 12b peuvent être disposés côte-à-côte ou l'un au dessus de l'autre au sein de la carcasse métallique 11.Conversely, in the version of Figure 4 , the heating apparatus 10 comprises a first radiating heating body 12a and a second radiating heating body 12b distinct from the first radiating heating body 12a. Said at least a first shielded element 15 is embedded in the material 17a of the first radiating heating body 12a while said at least one second shielded element 16 is embedded in the material 17b of the second radiating heating body 12b. The materials 17a and 17b may or may not be identical. The radiating heating bodies 12a and 12b can be placed side by side or one above the other within the metal frame 11.

En revenant à la Figure 3 maintenant, l'appareil de chauffage 10 comprend deux premiers éléments blindés 15 et un unique deuxième élément blindé 16, tous noyés dans la matière 17 d'un seul et unique corps de chauffe rayonnant 12 d'un seul tenant. L'agencement des premiers éléments blindés 15 et du deuxième élément blindé 16 est tel que le deuxième élément blindé 16 est disposé entre les deux premiers éléments blindés 15 suivant l'épaisseur du corps de chauffe rayonnant 12.Coming back to the Figure 3 now, the heater 10 comprises two first shielded elements 15 and a single second shielded element 16, all embedded in the material 17 of a single radiating heating body 12 in one piece. The arrangement of the first shielded elements 15 and of the second shielded element 16 is such that the second shielded element 16 is arranged between the two first shielded elements 15 depending on the thickness of the radiating heating body 12.

Cette organisation présente l'avantage d'améliorer encore plus la montée en température potentielle du corps de chauffe rayonnant 12.This organization has the advantage of further improving the potential rise in temperature of the radiating heating body 12.

De manière non représentée, il est possible de prévoir une variante de la Figure 3 dans laquelle l'appareil de chauffage 10 comprend deux deuxièmes éléments blindés 16 et un unique premier élément blindé 15, tous noyés dans la matière 17 d'un seul et unique corps de chauffe rayonnant 12 d'un seul tenant. L'agencement des deuxièmes éléments blindés 16 et du premier élément blindé 15 est tel que le premier élément blindé 15 est disposé entre les deux deuxièmes éléments blindés 16 suivant l'épaisseur du corps de chauffe rayonnant 12.In a manner not shown, it is possible to provide a variant of the Figure 3 in which the heater 10 comprises two second shielded elements 16 and a single first shielded element 15, all embedded in the material 17 of a single radiating heating body 12 in one piece. The arrangement of the second shielded elements 16 and of the first shielded element 15 is such that the first shielded element 15 is disposed between the two second shielded elements 16 depending on the thickness of the radiating heating body 12.

Là encore, cette disposition favorise une montée en température très rapide pour le corps de chauffe rayonnant 12.Here again, this arrangement promotes a very rapid rise in temperature for the radiating heating body 12.

Sur la Figure 3 par contre, le corps de chauffe rayonnant 12 unique et d'un seul tenant intègre un seul premier élément blindé 15 et un seul élément blindé 16.On the Figure 3 on the other hand, the single, one-piece radiating heating body 12 integrates a single first shielded element 15 and a single shielded element 16.

Par ailleurs, l'appareil de chauffage 10 comprend une unité de gestion logée dans la carcasse métallique 11 et pilotant le fonctionnement de chaque premier élément blindé 15 et son alimentation en courant électrique alternatif et le fonctionnement de chaque deuxième élément blindé 16 et son alimentation en courant électrique continu, en fonction d'un algorithme de stratégie prédéterminé enregistré dans une mémoire de l'unité de gestion.Furthermore, the heating apparatus 10 comprises a management unit housed in the metal frame 11 and controlling the operation of each first shielded element 15 and its alternating electric current supply and the operation of each second shielded element 16 and its power supply. direct electric current, according to a predetermined strategy algorithm stored in a memory of the management unit.

L'appareil de chauffage 10 peut comprendre un capteur de température apte à déterminer la température à l'extérieur du boitier et des éléments (filaires ou non) pour transmettre la valeur déterminée par le capteur de température à une entrée de l'unité de gestion. L'algorithme de gestion de chaque premier élément blindé 15 et de chaque deuxième élément blindé 16 peut notamment prendre en compte la valeur de la température à l'extérieur du boitier déterminée par le capteur de température.The heater 10 can include a temperature sensor capable of determining the temperature outside the box and elements (wired or not) for transmitting the value determined by the temperature sensor to an input of the management unit. . The management algorithm for each first shielded element 15 and each second shielded element 16 can in particular take into account the value of the temperature outside the box determined by the temperature sensor.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation représentés et décrits ci-avant, mais en couvre au contraire toutes les variantes.Of course, the invention is not limited to the embodiments shown and described above, but on the contrary covers all the variants thereof.
