Description
1 Élément chauffant à inertie thermique. La présente invention concerne un élément chauffant à inertie thermique, plus particulièrement un élément chauffant à inertie destiné à équiper un appareil de chauffage. Les éléments chauffants à inertie utilisés actuellement tels que des céramiques ou des fontes ont des caractéristiques radiatives bonnes avec des émissivités élevées. Un inconvénient de ces éléments chauffants est le fait que ces éléments ont les mêmes caractéristiques radiatives sur les faces avant et arrière ce qui génère des pertes thermiques au dos d'un appareil de chauffage dans lequel elles sont introduites. De plus, ces éléments chauffants comportent une source de chaleur constituée par une résistance électrique directement en contact avec le matériau inertiel constituant ces éléments chauffants à inertie. Cette disposition du matériau à inertie de sorte à englober la résistance électrique empêche un transfert direct de chaleur entre la source de chaleur et l'utilisateur de l'appareil de chauffage. Un but de la présente invention est de proposer des éléments chauffants exempts des inconvénients susmentionnés. Selon l'invention, ce but est atteint grâce à un élément chauffant à inertie destiné à équiper un appareil de chauffage remarquable en ce qu'il comprend : - une source de chaleur, préférentiellement électrique ; une coque apte à être chauffée par la source de chaleur et définissant au moins un compartiment destiné à recevoir un matériau à inertie, cette coque étant configurée, d'une part, pour transmettre directement la chaleur à son environnement extérieur et, d'autre part, pour conduire la chaleur au matériau à inertie. Un tel élément chauffant possède une meilleure réactivité et une plus grande capacité inertielle que les éléments chauffants existants, permettant ainsi de limiter les variations brutales de température. Selon un exemple de réalisation, la source de chaleur est constituée par une résistance électrique chauffante. Selon un mode de réalisation avantageux, la coque définit deux compartiments disposés de part et d'autre de la résistance électrique chauffante.1 Heating element with thermal inertia. The present invention relates to a heating element with thermal inertia, more particularly to a heating element with inertia intended to equip a heating apparatus. Currently used inertial heaters such as ceramics or cast irons have good radiative characteristics with high emissivities. A disadvantage of these heating elements is the fact that these elements have the same radiative characteristics on the front and rear faces which generates heat losses on the back of a heater in which they are introduced. In addition, these heating elements comprise a heat source consisting of an electrical resistance directly in contact with the inertial material constituting these inertia heating elements. This arrangement of the inertia material to encompass the electrical resistance prevents direct heat transfer between the heat source and the user of the heater. An object of the present invention is to provide heating elements free from the aforementioned drawbacks. According to the invention, this object is achieved by means of an inertial heating element intended to equip a remarkable heating apparatus in that it comprises: a heat source, preferentially electric; a shell able to be heated by the heat source and defining at least one compartment intended to receive a material with inertia, this shell being configured, on the one hand, to directly transmit the heat to its external environment and, on the other hand , to conduct the heat to the inertia material. Such a heating element has a better reactivity and a greater inertial capacity than the existing heating elements, thus making it possible to limit the sudden changes in temperature. According to an exemplary embodiment, the heat source is constituted by a heating electric resistance. According to an advantageous embodiment, the shell defines two compartments disposed on either side of the electric heating resistor.
3035197 2 Selon un exemple de réalisation avantageux, chaque compartiment est cloisonné de sorte à former une pluralité de canaux thermiques dans lesdits compartiments. Selon un mode de réalisation avantageux, le matériau à inertie contenu dans le compartiment est un solide tel que de la céramique, de la fonte, ou un liquide tel qu'un fluide caloporteur, ou une combinaison d'un matériau à inertie solide et d'un matériau à inertie liquide ou un matériau à changement de phase. Selon un exemple de réalisation avantageux, le matériau à inertie contenu dans le ou les compartiments est de la roche de silice pure, calcinée et broyée à granulométrie variable. Selon un exemple de réalisation avantageux, la coque est réalisée en tout matériau présentant de bonnes caractéristiques de conduction thermique et de faible émissivité. Selon, un exemple de réalisation préféré, la coque est réalisée dans un matériau ayant une émissivité comprise entre 0 et 0,5. Selon un mode de réalisation préféré, la coque est constituée par un profilé en aluminium. Selon un exemple de réalisation avantageux, les compartiments sont ouverts à au moins l'une de leurs extrémités pour permettre le remplissage du matériau à inertie et coopèrent avec un dispositif de fermeture. Selon un exemple de réalisation avantageux, l'élément chauffant à inertie est fermé à chacune de ses extrémités par un dispositif de fermeture et est configuré pour pouvoir être fixé à l'intérieur d'un appareil de chauffage par l'intermédiaire de moyens de fixation dont sont munis lesdits dispositifs de fermeture. Selon un exemple de réalisation avantageux, le dispositif de fermeture est réalisé dans un matériau dont le coefficient de dilatation est inférieur à celui du matériau dans lequel est réalisée la coque. La présente invention concerne encore les appareils de chauffage comprenant au moins un élément chauffant à inertie comportant au moins l'une des caractéristiques susmentionnées. Les buts, caractéristiques et avantages ci-dessus, et d'autres encore, ressortiront mieux de la description détaillée qui suit et des dessins annexés dans lesquels : 3035197 3 La figure 1 est une vue en perspective d'un exemple de réalisation de l'élément chauffant à inertie selon l'invention. La figure 2 est une vue en coupe transversale de l'élément chauffant à inertie de la figure 1. On se réfère auxdits dessins pour décrire des exemples intéressants quoique nullement limitatifs, de réalisation de l'élément chauffant à inertie selon l'invention. L'élément chauffant à inertie 1 selon l'invention comprend : - une source de chaleur 2 par exemple constituée par une résistance électrique ; - une coque 3 apte à être chauffée par la source de chaleur et définissant au moins un compartiment 4 destiné à recevoir un matériau à inertie 5. La coque 3 est configurée, d'une part, pour transmettre de la chaleur à son environnement extérieur et, d'autre part, pour conduire la chaleur au matériau à inertie et chauffer ce dernier. De manière avantageuse, lorsque l'élément chauffant selon l'invention possède un seul compartiment 4, ce dernier est configuré de sorte à être centré sur la source de chaleur 2, de sorte que ce dernier chauffe uniformément ledit compartiment ainsi que le matériau à inertie 5 qu'il renferme. Selon l'exemple illustré, la coque 3 définit deux compartiments 4 disposés de part et d'autre de la résistance électrique 2. Ces compartiments présentent une section de forme pétaloïde dont la largeur décroit en s'éloignant de la résistance chauffante 2. De la sorte, cette forme particulière rend la température de surface de la source de chaleur 2 plus homogène dans les phases de chauffage car la quantité de matière à inertie est plus importante à l'endroit où le potentiel de stockage de chaleur est plus important, c'est-à-dire à proximité de ladite source de chaleur. Ce potentiel décroit en s'éloignant de ladite source de chaleur de sorte que, inversement, la quantité de matière à inertie est moins importante à l'endroit où le potentiel de stockage de chaleur est le moins important, c'est-à-dire à distance de ladite source de chaleur. Selon un exemple de réalisation non illustré, chaque compartiment 4 est cloisonné de sorte à former une pluralité de chambres à l'intérieur de chaque compartiment 4. De telles cloisons définissent des canaux thermiques dans les compartiments 4 permettant d'augmenter la conductivité thermique dans le matériau inertiel.According to an advantageous exemplary embodiment, each compartment is partitioned so as to form a plurality of heat channels in said compartments. According to an advantageous embodiment, the inertia material contained in the compartment is a solid such as ceramic, cast iron, or a liquid such as a coolant, or a combination of a solid inertia material and a liquid inertia material or a phase change material. According to an advantageous exemplary embodiment, the material with inertia contained in the compartment or compartments is pure silica rock, calcined and milled to variable particle size. According to an advantageous embodiment, the shell is made of any material having good thermal conduction characteristics and low emissivity. According to a preferred embodiment, the shell is made of a material having an emissivity of between 0 and 0.5. According to a preferred embodiment, the shell is constituted by an aluminum profile. According to an advantageous embodiment, the compartments are open at at least one of their ends to allow filling of the inertia material and cooperate with a closure device. According to an advantageous exemplary embodiment, the inertial heating element is closed at each of its ends by a closure device and is configured to be fixed inside a heating device by means of fixing means. which are provided with said closure devices. According to an advantageous embodiment, the closure device is made of a material whose expansion coefficient is less than that of the material in which the shell is made. The present invention further relates to heating apparatus comprising at least one inertia heating element having at least one of the above-mentioned features. The foregoing and other objects, features and advantages will become more apparent from the following detailed description and accompanying drawings, in which: Figure 1 is a perspective view of an exemplary embodiment of the present invention; inertial heating element according to the invention. FIG. 2 is a cross-sectional view of the inertial heating element of FIG. 1. Referring to the drawings, the following is an example of an interesting example, although not limiting, of embodiment of the inertial heating element according to the invention. The inertia heating element 1 according to the invention comprises: a heat source 2, for example constituted by an electrical resistance; a shell 3 capable of being heated by the heat source and defining at least one compartment 4 intended to receive a material with inertia 5. The shell 3 is configured, on the one hand, to transmit heat to its external environment and on the other hand, to conduct the heat to the inertia material and heat the latter. Advantageously, when the heating element according to the invention has a single compartment 4, the latter is configured so as to be centered on the heat source 2, so that the heat source uniformly heats said compartment and the inertia material. 5 that it contains. According to the illustrated example, the shell 3 defines two compartments 4 disposed on either side of the electrical resistance 2. These compartments have a section of petaloid shape whose width decreases away from the heating resistor 2. From the so, this particular form makes the surface temperature of the heat source 2 more homogeneous in the heating phases because the amount of inertia material is greater at the location where the heat storage potential is greater, that is, near said heat source. This potential decreases away from said source of heat so that, conversely, the amount of inertia material is less important where the heat storage potential is the least important, that is to say away from said heat source. According to an embodiment not shown, each compartment 4 is partitioned so as to form a plurality of chambers inside each compartment 4. Such partitions define thermal channels in the compartments 4 to increase the thermal conductivity in the inertial material.
3035197 4 De manière avantageuse, la coque 3 est réalisée en tout matériau présentant de bonnes caractéristiques de conduction thermique et une faible émissivité. Selon un mode de réalisation avantageux, ladite coque 3 est réalisée dans un matériau présentant une émissivité comprise entre 0 et 0,5. Préférentiellement, ladite coque est constituée par un profilé en aluminium. De plus, pour augmenter la surface d'échange thermique de l'élément chauffant selon l'invention, au moins une portion de ladite coque 3 présente une surface rugueuse définissant des vaguelettes ou ailettes, améliorant ainsi le transfert thermique entre l'élément chauffant et son environnement. Dans un mode de réalisation, le matériau à inertie 5 contenu dans les compartiments 4 est un solide tel que de la céramique ou de la fonte. Dans un autre mode de réalisation, le matériau à inertie est un liquide tel qu'un fluide caloporteur (par exemple une huile végétale ou minérale). Dans encore un autre mode de réalisation, les compartiments 4 reçoivent une combinaison d'un matériau à inertie solide et d'un matériau à inertie liquide ou d'un matériau à changement de phase. Dans un mode de réalisation préféré, le matériau inertiel 5 est de la roche de silice pure, calcinée et broyée à granulométrie variable. En effet, la roche de silice pure est un matériau présentant de bonnes qualités inertielles. De plus, la granulométrie variable permet d'optimiser le remplissage des compartiments 4. L'élément chauffant ainsi réalisé est tel que la source de chaleur 2 n'est pas en contact direct avec le matériau à inertie 5. De la sorte, la source de chaleur 2 chauffe dans un premier temps la coque 3, puis la chaleur est stockée dans le matériau inertiel, ce qui procure une meilleure réactivité de l'élément chauffant selon l'invention. Avantageusement, les compartiments 4 sont ouverts à au moins l'une de leurs extrémités pour permettre le remplissage du matériau à inertie et coopèrent avec un dispositif de fermeture 6, encore appelé bouchon dans le présent exposé. Ces bouchons 6 sont réalisés dans un matériau dont le coefficient de dilatation est inférieur à celui du matériau dans lequel est réalisée la coque 3, de sorte à améliorer la fermeture des compartiments 4 par la réaction de dilatation des matériaux constituant l'élément chauffant à inertie 1 lors de sa montée en température. De préférence, les bouchons 6 destinés à fermer les compartiments 4 à au moins l'une de leurs extrémités sont réalisés en acier. En effet, la coque étant préférentiellement réalisée en aluminium, elle présente un coefficient de dilatation supérieur à celui des 3035197 bouchons exécutés en acier. Ainsi, lorsque l'élément chauffant à inertie 1 chauffe, l'aluminium constituant la coque chauffe et se dilate de manière plus importante que l'acier constituant les bouchons ce qui a pour effet d'améliorer la fermeture des compartiments 4. Cette configuration permet d'assurer une bonne étanchéité des compartiments 4. Toutefois, pour améliorer cette étanchéité, les compartiments sont munis de joints d'étanchéité. Dans un mode de réalisation, les bouchons 6 sont fixés, à demeure ou de manière amovible à la coque 3, par exemple par sertissage ou vissage. De manière avantageuse, le dispositif de fermeture comporte des moyens de fixation (non représentés) permettant la fixation de l'élément chauffant à inertie selon l'invention à l'intérieur d'un appareil de chauffage. L'émissivité de l'élément chauffant selon l'invention est réglable et orientable grâce à différents traitements de surface connus en soin tels que peinture, sablage, décrochage chimique, etc. La présente invention concerne encore les appareils de chauffage comprenant au moins un élément chauffant à inertie comportant au moins l'une des caractéristiques susmentionnées.Advantageously, the shell 3 is made of any material having good thermal conduction characteristics and low emissivity. According to an advantageous embodiment, said shell 3 is made of a material having an emissivity of between 0 and 0.5. Preferably, said shell is constituted by an aluminum profile. In addition, to increase the heat exchange surface of the heating element according to the invention, at least a portion of said shell 3 has a rough surface defining ripples or fins, thus improving the heat transfer between the heating element and its environment. In one embodiment, the inertia material contained in the compartments 4 is a solid such as ceramic or cast iron. In another embodiment, the inertia material is a liquid such as a coolant (for example a vegetable or mineral oil). In yet another embodiment, the compartments 4 receive a combination of a solid inertia material and a liquid inertia material or a phase change material. In a preferred embodiment, the inertial material is pure silica rock, calcined and milled to a variable size. Indeed, pure silica rock is a material with good inertial qualities. In addition, the variable particle size makes it possible to optimize the filling of the compartments 4. The heating element thus produced is such that the heat source 2 is not in direct contact with the inertia material 5. In this way, the source heat 2 initially heats the shell 3, then the heat is stored in the inertial material, which provides a better reactivity of the heating element according to the invention. Advantageously, the compartments 4 are open at at least one of their ends to allow filling of the inertia material and cooperate with a closure device 6, also called plug in the present disclosure. These plugs 6 are made of a material whose coefficient of expansion is less than that of the material in which the shell 3 is made, so as to improve the closure of the compartments 4 by the expansion reaction of the materials constituting the inertia heating element. 1 when it rises in temperature. Preferably, the plugs 6 intended to close the compartments 4 at at least one of their ends are made of steel. Indeed, the hull is preferably made of aluminum, it has a coefficient of expansion greater than that of 3035197 plugs made of steel. Thus, when the inertia heating element 1 heats, the aluminum constituting the shell heats and expands more significantly than the steel constituting the plugs which has the effect of improving the closure of the compartments 4. This configuration allows to ensure good sealing of the compartments 4. However, to improve this seal, the compartments are provided with gaskets. In one embodiment, the plugs 6 are fixed, permanently or removably to the shell 3, for example by crimping or screwing. Advantageously, the closure device comprises fastening means (not shown) for fixing the inertial heating element according to the invention inside a heater. The emissivity of the heating element according to the invention is adjustable and adjustable thanks to various surface treatments known in care such as painting, sanding, chemical stall, etc. The present invention further relates to heating apparatus comprising at least one inertia heating element having at least one of the above-mentioned features.
