Description

La présente invention concerne un radiateur sèche-serviette à fluide caloporteur de type arborescent.The present invention relates to a towel-type heat sink radiator arborescent type.

Les sèche-serviettes électriques à fluide caloporteur d'un type très répandu sont le plus souvent constitués d'une pluralité de barreaux chauffants (cylindriques ou sous forme de lames) sensiblement horizontaux dans lesquels circule ledit fluide. Dans les radiateurs de type "échelle", chaque barreau est relié, au niveau de chacune de ses extrémités, à deux collecteurs généralement verticaux qui sont d'une part une conduite d'arrivée du fluide chaud dans les barreaux et d'autre part une conduite de collecte du liquide refroidi. Le fluide caloporteur est chauffé par une résistance électrique de type thermoplongeur disposée en partie inférieure de la conduite de distribution du fluide chauffé. Ce fluide circule en boucle fermée dans l'ensemble formé par ces barreaux et conduites constituant le radiateur.Electric towel warmers heat transfer fluid of a widespread type most often consist of a plurality of heating rods (cylindrical or blades) substantially horizontal in which circulates said fluid. In radiators of "ladder" type, each bar is connected, at each of its ends, to two generally vertical collectors which are on the one hand a pipe for the arrival of hot fluid in the bars and on the other hand a coolant collection line. The coolant is heated by an immersion heater type electric heater disposed in the lower portion of the heated fluid distribution line. This fluid circulates in a closed loop in the assembly formed by these bars and pipes constituting the radiator.

Ces sèche-serviettes de type échelle présentent l'inconvénient d'une ergonomie d'insertion des serviettes qui n'est pas optimisée car il est nécessaire d'introduire les serviettes de face, les collecteurs fermant l'espace libre entre les barreaux au niveau des côtés latéraux du radiateur.These scale-type towel warmers have the disadvantage of an ergonomics of insertion of towels that is not optimized because it is necessary to introduce the towels face, collectors closing the free space between the bars at the level lateral sides of the radiator.

Pour améliorer l'ergonomie et l'esthétique des sèche-serviettes, il a été proposé des sèche-serviettes de type arborescent. Ces appareils se différencient des radiateurs précédents en ce que les deux collecteurs d'alimentation et de collecte sensiblement verticaux sont disposés à proximité l'un de l'autre, laissant libre au moins une extrémité des tubes chauffants horizontaux.To improve the ergonomics and aesthetics of towel warmers, it has been proposed tree-type towel warmers. These devices are different from previous radiators in that the two substantially vertical supply and collection manifolds are arranged close to each other, leaving free at least one end of the horizontal heating tubes.

Dans ces radiateurs, l'introduction des serviettes est grandement facilitée car il est possible de glisser directement les serviettes, par exemple pliées en deux, entre les tubes chauffants, par le côté du radiateur. Pour faciliter la circulation du fluide caloporteur dans les tubes chauffants, sont prévus des tubes de connexion ou raccordement appelés "cigares" permettant de relier les extrémités distales de certaines des tubes chauffants entre eux. Le fluide caloporteur est ainsi forcé à circuler d'un tube chauffant vers au moins un tube chauffant adjacent en passant par ce "cigare". Dans l'exemple de l'art antérieur représenté sur la figure 7, un "cigare" 20 relie chaque groupe de trois tubes chauffants 4.In these radiators, the introduction of towels is greatly facilitated because it is possible to directly slide the towels, for example folded in half, between the heating tubes, by the side of the radiator. To facilitate the circulation of the coolant in the heating tubes, there are provided connection tubes or connection called "cigars" for connecting the distal ends of some of the heating tubes together. The heat transfer fluid is thus forced to flow from a heating tube to at least one tube heating adjacent through this "cigar". In the example of the prior art shown in the figure 7 , a "cigar" 20 connects each group of three heating tubes 4.

Ces radiateurs sèche-serviettes posent cependant quelques difficultés de fabrication. En effet, pour la pose des ces "cigares", il est nécessaire d'emboutir chaque tube chauffant au niveau d'une de ses extrémités et de souder ledit "cigare". Outre le coût du matériau et le temps de soudure, il apparaît des problèmes d'étanchéité plus nombreux pour ces radiateurs. En outre, certains tubes chauffants étant connectés à la conduite de distribution et d'autres tubes chauffants connectés à la conduite de collecte du fluide refroidi, ces tubes ne sont pas tous identiques, ce qui constitue un inconvénient lors de la fabrication du radiateur. Il est en effet nécessaire de les repérer, perforer différemment, puis les trier, etc. En outre, les tubes de connexion, appelés "cigares", perturbent l'esthétique de l'appareil. Il apparaît en outre que l'homogénéité thermique n'est pas optimisée et peut varier fortement d'un tube chauffant à l'autre. En effet, seules certains tubes chauffants sont alimentés directement à la conduite de distribution de fluide chauffé.These towel radiators, however, pose some manufacturing difficulties. Indeed, for the installation of these "cigars", it is necessary to stamp each heating tube at one of its ends and to weld said "cigar". In addition to the cost of the material and the welding time, there are more sealing problems for these radiators. In addition, some heating tubes being connected to the distribution line and other heating tubes connected to the cooled fluid collection line, these tubes are not all identical, which is a disadvantage in the manufacture of the radiator. It is indeed necessary to locate them, perforate differently, then sort them, etc. In addition, connection tubes, called "cigars", disrupt the aesthetics of the device. It also appears that the thermal homogeneity is not optimized and can vary greatly from one heating tube to another. Indeed, only certain heating tubes are fed directly to the heated fluid distribution line.

Il a été proposé, dans le brevet européen EP-0.674.148 , des sèche-serviettes électriques à fluide caloporteur arborescent ne comportant pas de tubes de connexion. Ces appareils ont la même structure arborescente que les radiateurs décrits précédemment avec les différences suivantes :

  • chaque tube chauffant est relié individuellement à chacun des deux collecteurs. Il apparaît donc que tous les tubes chauffants sont identiques,
  • l'extrémité libre des tubes chauffants est obturée et il n'y a pas de communication directe desdits tubes entre eux,
  • cependant, afin de faciliter l'homogénéisation du fluide caloporteur, il est prévu, à l'intérieur de chaque tube chauffant généralement sous forme d'une lame aplatie, une circulation forcée afin que l'orifice d'arrivée du fluide chauffé n'alimente pas directement l'orifice de sortie. La conception de la lame oblige le renouvellement de l'ensemble du fluide dans chaque lame par le biais d'un circuit aller-retour réalisé par des moyens de déflection du fluide tel qu'une cloison intermédiaire (sous la forme par exemple d'une pièce longitudinale) disposée à l'intérieur de la lame, ou de matériau embouti sur une majeure partie de la longueur de la lame afin de séparer le volume interne de celle-ci en deux zones distinctes.
It has been proposed in the European patent EP-0674148 Electric towel warmers with tree heat transfer fluid do not have connecting tubes. These devices have the same tree structure as the previously described radiators with the following differences:
  • each heating tube is individually connected to each of the two collectors. It therefore appears that all the heating tubes are identical,
  • the free end of the heating tubes is closed and there is no direct communication of said tubes together,
  • however, in order to facilitate the homogenization of the coolant, there is provided, inside each heating tube generally in the form of a flattened blade, a forced circulation so that the inlet orifice of the heated fluid is not fed. not directly the outlet. The design of the blade forces the renewal of all the fluid in each blade through a return circuit made by fluid deflection means such as a intermediate partition (in the form for example of a longitudinal part) arranged inside the blade, or material stamped over a major part of the length of the blade in order to separate the internal volume thereof into two zones distinct.

La fabrication des lames d'un tel radiateur reste coûteuse car il est nécessaire de séparer la chambre intérieure de chacune des lames en plusieurs compartiments communicants.The manufacture of the blades of such a radiator is expensive because it is necessary to separate the inner chamber of each of the blades in several communicating compartments.

Un des buts de la présenté invention est de proposer une fabrication simplifiée des tubes chauffants, afin de réduire le prix de revient du radiateur sèche-serviette, sans réduction des performances thermiques dudit radiateur.One of the aims of the present invention is to propose a simplified manufacturing of the heating tubes, in order to reduce the cost price of the towel-drying radiator, without reducing the thermal performance of said radiator.

Un autre but de la présente invention est de proposer une conception des éléments constitutifs du radiateur permettant la réalisation de structures d'esthétiques variées tout en conservant la forme arborescente de ces sèche-serviettes.Another object of the present invention is to provide a design of the constituent elements of the radiator for the realization of various aesthetic structures while maintaining the tree shape of these towel warmers.

A cet effet, la présente invention concerne un radiateur sèche-serviettes de type arborescent à fluide caloporteur, circulant à l'intérieur de tubes chauffants sensiblement horizontaux, chaque tube chauffant étant connecté d'une part à une conduite de distribution du fluide chauffé, par l'intermédiaire d'un orifice d'entrée disposé en vis-à-vis d'un orifice de distribution ménagé dans la paroi de la conduite de distribution, et d'autre part à une conduite de collecte du fluide refroidi, par l'intermédiaire d'un orifice de sortie ménagé dans la paroi de la conduite de collecte, disposé en vis-à-vis d'un orifice de collecte, la ou lesdites conduite(s) de distribution et de collecte formant montant(s) de fixation des tubes chauffants, caractérisé en ce que les conduites de distribution et de collecte sont disposées à proximité l'une de l'autre, laissant libre au moins l'une des extrémités des tubes chauffants, et en ce que chaque tube chauffant est de forme parallélépipédique et comporte une chambre interne unique, sans cloisonnement, dans laquelle circule le fluide caloporteur, l'orifice d'entrée et l'orifice de sortie du fluide dans chaque tube chauffant étant ménagés à des hauteurs différentes.To this end, the present invention relates to a radiator-type heated towel rail circulating inside substantially horizontal heating tubes, each heating tube being connected on the one hand to a heated fluid distribution line, by via an inlet orifice disposed opposite a dispensing orifice formed in the wall of the distribution pipe, and on the other hand to a pipe for collecting the cooled fluid, by the intermediate an outlet orifice formed in the wall of the collection pipe, arranged opposite a collection orifice, the at least one distribution and collection duct (s) forming a fixing amount (s). heating tubes, characterized in that the distribution and collection lines are arranged close to each other, leaving at least one end of the heating tubes free, and in that each heating tube is shaped by allelepiped and comprises a single internal chamber, without partitioning, in which circulates the heat transfer fluid, the inlet orifice and the fluid outlet orifice in each heating tube being arranged at different heights.

Il a été constaté de manière surprenante que malgré l'absence de cloisonnement dans les tubes chauffants, et malgré l'absence de tubes connecteurs ("cigares") entre les extrémités distales de tubes chauffants adjacents, la température du fluide caloporteur s'homogénéise dans l'ensemble du radiateur, aussi rapidement que pour les radiateurs de l'art antérieur, lorsque l'orifice d'entrée du fluide caloporteur est ménagé à une hauteur supérieure à l'orifice de sortie dudit fluide.It has surprisingly been found that despite the absence of partitioning in the heating tubes, and despite the absence of connector tubes ("cigars") between the distal ends of adjacent heating tubes, the temperature of the coolant is homogenized in the radiator assembly, as quickly as for radiators of the prior art, when the heat transfer fluid inlet orifice is provided at a height greater than the outlet orifice of said fluid.

Selon un premier mode de réalisation de l'invention, l'orifice d'entrée et l'orifice de sortie de chaque tube chauffant sont ménagés à proximité de la même extrémité dudit tube chauffant. L'autre extrémité du tube chauffant est libre, et peut ainsi servir de support de serviettes par introduction latérale entre lesdites extrémités libres des tubes.According to a first embodiment of the invention, the inlet orifice and the outlet orifice of each heating tube are formed near the same end of said heating tube. The other end of the heating tube is free, and can thus serve as a towel holder by lateral introduction between said free ends of the tubes.

Selon un deuxième mode de réalisation de l'invention, l'orifice d'entrée et l'orifice de sortie de chaque tube chauffant sont ménagés au niveau de la zone médiane dudit tube chauffant. Ainsi, il est possible de disposer les serviettes de part et d'autre des conduites de distribution et de collecte du fluide caloporteur sur les portions des tubes chauffants dépassant de part et d'autre.According to a second embodiment of the invention, the inlet orifice and the outlet orifice of each heating tube are formed at the central zone of said heating tube. Thus, it is possible to arrange the towels on either side of the heat transfer fluid distribution and collection pipes on the portions of the heating tubes protruding from either side.

Différentes variantes peuvent être prévues pour les conduites de distribution et de collecte du fluide caloporteur.Different variants can be provided for the distribution and collection lines of the heat transfer fluid.

Selon une première variante, le radiateur comporte deux conduites séparées, l'une pour la distribution du fluide chauffé et l'autre pour la collecte du fluide refroidi, ces deux conduites formant les montants dudit radiateur.According to a first variant, the radiator comprises two separate conduits, one for the distribution of the heated fluid and the other for the collection of the cooled fluid, these two pipes forming the amounts of said radiator.

Selon une deuxième variante, les conduites de distribution et de collecte forment un élément tubulaire à double chambre, constituant un montant unique ; ainsi par exemple la première chambre constitue la conduite de distribution du fluide chauffé et la seconde chambre constitue la conduite de collecte du fluide refroidi.According to a second variant, the distribution and collection lines form a double chamber tubular element, constituting a single amount; thus for example the first chamber is the distribution line of the heated fluid and the second chamber is the collection line of the cooled fluid.

Selon une troisième variante, les conduites de distribution et de collecte sont confondues sur la totalité de leur longueur, formant une conduite commune (c'est-à-dire non compartimentée) et constituant un montant unique. On a alors une conduite unique. L'orifice d'entrée du fluide caloporteur chaud dans le tube chauffant est alors celui qui est situé à l'aplomb de la résistance chauffante ou de l'arrivée de fluide chaud depuis la conduite de chauffage central.According to a third variant, the distribution and collection lines are merged over their entire length, forming a common (that is to say, non-compartmentalized) pipe and constituting a single amount. We then have a unique conduct. The inlet port of the heat transfer fluid in the tube heating is then one which is located above the heating resistor or the arrival of hot fluid from the central heating pipe.

De manière avantageuse, le diamètre des orifices d'entrée des tubes est sensiblement identique quel que soit le tube chauffant. De même, il est avantageux que le diamètre des orifices de sortie des tubes soit sensiblement identique quel que soit le tube chauffant.Advantageously, the diameter of the inlet ports of the tubes is substantially identical regardless of the heating tube. Similarly, it is advantageous that the diameter of the outlet orifices of the tubes is substantially identical regardless of the heating tube.

Il est également préféré que la position des orifices respectifs ménagés dans les parois de chaque tube chauffant est sensiblement identique quel que soit le tube chauffant.It is also preferred that the position of the respective orifices provided in the walls of each heating tube is substantially identical regardless of the heating tube.

Ainsi, tous les tubes chauffants sont identiques entre eux en ce qui concerne la position des orifices et leur diamètre. Leur fabrication et leur manutention en est ainsi facilitée pour l'assemblage du radiateur.Thus, all the heating tubes are identical to each other with respect to the position of the orifices and their diameter. Their manufacture and handling is thus facilitated for the assembly of the radiator.

Selon un mode de réalisation avantageux, les orifices d'entrée et de sortie des tubes chauffants sont de diamètre supérieur ou égal au diamètre des orifices de distribution et des orifices de collecte desdites conduites de distribution et de collecte.According to an advantageous embodiment, the inlet and outlet ports of the heating tubes have a diameter greater than or equal to the diameter of the distribution orifices and the collection orifices of said distribution and collection lines.

Enfin, pour faciliter encore l'homogénéisation générale de la température du fluide caloporteur dans l'ensemble du radiateur, il peut être prévu que les orifices ménagés dans les parois des conduites de distribution et de collecte soient de taille variable, les diamètres des orifices disposés en partie supérieure du radiateur étant par exemple de taille inférieure aux orifices disposés en partie inférieure du radiateur.Finally, to further facilitate the general homogenization of the temperature of the heat transfer fluid in the entire radiator, it may be provided that the orifices in the walls of the distribution and collection pipes are of variable size, the diameters of the orifices arranged in the upper part of the radiator being for example smaller than the orifices arranged in the lower part of the radiator.

Il est également envisageable que les diamètres des orifices de la conduite de distribution soient différents de ceux de la conduite de collecte.It is also conceivable that the diameters of the orifices of the distribution pipe are different from those of the collection pipe.

Comme visible sur les figures 1 et 2, le radiateur sèche-serviettes selon la présente invention, est de type arborescent. A la différence des radiateurs sèche-serviettes de type échelle, il présente un seul montant 3 servant de support aux tubes chauffants 4 sensiblement horizontaux.As visible on Figures 1 and 2 , the towel radiator according to the present invention, is arborescent type. Unlike ladder-type towel radiators, it has a single upright 3 serving as a support for substantially horizontal heating tubes 4.

Dans le mode de réalisation selon la figure 1, le radiateur 1 comporte un montant 3 unique latéral, les tubes chauffants étant fixés sur ce montant 3 au niveau de l'une de leurs extrémités, laissant libre la seconde extrémité du tube pour y disposer les serviettes.In the embodiment according to figure 1 , the radiator 1 comprises a single lateral amount 3, the heating tubes being fixed on this upright 3 at one of their ends, leaving free the second end of the tube to arrange the towels.

Selon le mode de réalisation de la figure 2, le radiateur 2 comporte un montant 3 unique central, les tubes chauffants 4 étant fixés à ce montant au niveau de leur zone médiane, laissant libre les deux extrémités des tubes, pour servir de porte-serviettes.According to the embodiment of the figure 2 the radiator 2 comprises a single central upright 3, the heating tubes 4 being fixed to this upright at their central zone, leaving the two ends of the tubes free to serve as a towel rail.

Dans ces radiateurs de type arborescent, les tubes chauffants horizontaux qui supportent les serviettes sont donc montés en porte-à-faux sur ce montant. La pose des serviettes est facile car il est possible de les disposer sur les tubes chauffants en les glissant latéralement.In these radiators of arborescent type, the horizontal heating tubes that support the towels are mounted cantilever on this amount. The installation of the towels is easy because it is possible to arrange them on the heating tubes by sliding them laterally.

Les tubes chauffants 4 proprement dits sont réalisés sous forme de lames creuses de section rectangulaire. Un des grands côtés de la lame constitue la face d'applique de ladite lame contre les conduites de distribution et de collecte formant montant ; les orifices d'entrée et de sortie du fluide dans la lame chauffante sont ménagés dans ladite face d'applique.The heating tubes 4 themselves are made in the form of hollow blades of rectangular section. One of the long sides of the blade constitutes the face of application of said blade against the distribution and collection lines forming amount; the inlet and outlet ports of the fluid in the heating blade are formed in said face of application.

A l'intérieur de ces tubes chauffants circule le fluide caloporteur du radiateur. Ce fluide caloporteur circulant en boucle fermée peut être chauffé au moyen d'une résistance de type thermoplongeur 9, reliée à une alimentation électrique 10, placée dans la partie inférieure du montant 3. En variante, le fluide caloporteur peut être issu d'une installation de chauffage central.Inside these heating tubes circulates the heat transfer fluid of the radiator. This coolant circulating in closed loop can be heated by means of a heater-type resistor 9, connected to a power supply 10 placed in the lower part of the upright 3. Alternatively, the heat-transfer fluid can be obtained from an installation central heating.

Le fluide caloporteur arrive au niveau des tubes chauffants 4 par une conduite de distribution du fluide chaud et repart des tubes chauffants par une conduite de collecte du fluide refroidi. Selon une variante présentée aux figures 3 et 4, les conduites de distribution et de collecte forment une conduite commune et constituent le montant 3 du radiateur. Le fluide caloporteur quitte cette conduite commune par un orifice 6 ménagé dans cette dernière et pénètre dans le tube chauffant 4 par un orifice d'entrée 5. Après avoir réchauffé le tube chauffant 4, le fluide caloporteur refroidi quitte ce tube chauffant 4 par un orifice 7 ménagé dans ledit tube chauffant et rejoint la conduite formant le montant 3 par l'orifice 8 ménagé dans ladite conduite en vis-à-vis de l'orifice 7. Le tube chauffant 4 est également entièrement creux et ne comporte aucun moyen de déflection ni compartiment qui forcerait le fluide à effectuer une trajectoire particulière à l'intérieur de ce dernier, hormis la convection naturelle.The heat transfer fluid arrives at the level of the heating tubes 4 by a hot fluid distribution line and leaves the heating tubes via a cooled fluid collection line. According to a variant presented to Figures 3 and 4 , the distribution and collection lines form a common pipe and constitute the amount 3 of the radiator. The coolant leaves this common pipe through an orifice 6 formed in the latter and enters the heating tube 4 through an inlet port 5. After heating the heating tube 4, the cooled heat transfer fluid leaves the heating tube 4 through an orifice 7 formed in said heating tube and joined the pipe forming the upright 3 through the orifice 8 formed in said pipe vis-à-vis the orifice 7. The heating tube 4 is also completely hollow and has no deflection means or compartment that would force the fluid to perform a particular trajectory inside the latter, except natural convection.

De manière avantageuse, les orifices 5 et 7 ménagés dans le tube chauffant sont de diamètre égal ou supérieur à ceux des orifices 6, 8 ménagés dans la conduite formant montant 3. Ainsi, dans ce dernier cas (diamètre supérieur), pour optimiser encore la circulation du fluide dans le radiateur, sans introduire de moyens de déflection du fluide à l'intérieur des tubes chauffants, il est possible de modifier la section de passage du fluide (conditionnée par le diamètre le plus petit) de la conduite vers les tubes chauffants et vice-versa, en modifiant le diamètre d'au moins certains des orifices ménagés dans la conduite, et de préférence uniquement ces derniers, les orifices des tubes chauffants restant inchangés et avantageusement tous identiques.Advantageously, the orifices 5 and 7 formed in the heating tube are of diameter equal to or greater than those of the orifices 6, 8 formed in the pipe forming the upright 3. Thus, in the latter case (greater diameter), to further optimize the circulation of the fluid in the radiator, without introducing fluid deflection means inside the heating tubes, it is possible to modify the fluid passage section (conditioned by the smallest diameter) of the pipe to the heating tubes and vice versa, by changing the diameter of at least some of the orifices in the pipe, and preferably only the latter, the orifices of the heating tubes remaining unchanged and advantageously all identical.

Selon une autre variante de l'invention schématisée aux figures 5 et 6, la conduite de distribution 11 du fluide caloporteur chauffé par une résistance 17 connectée à une alimentation électrique 18, amène le fluide chaud au tube chauffant 4 au moyen d'un orifice 13 ménagé dans ledit tube chauffant et d'un orifice 14 ménagé dans la conduite de distribution 11. Après refroidissement le fluide caloporteur refroidi quitte le tube chauffant 4 par un orifice 15 ménagé dans ledit tube chauffant et rejoint la conduite de collecte du fluide froid 12 par l'orifice de collecte 16 ménagé dans cette dite conduite de collecte.According to another variant of the invention shown diagrammatically Figures 5 and 6 , the distribution line 11 of the coolant heated by a resistor 17 connected to a power supply 18, brings the hot fluid to the heating tube 4 by means of an orifice 13 formed in said heating tube and an orifice 14 formed in the distribution pipe 11. After cooling the cooled heat transfer fluid leaves the heating tube 4 through an orifice 15 formed in said heating tube and joins the cold fluid collection pipe 12 through the collection port 16 formed in said collection pipe.

Dans cette variante, la conduite de distribution 11 et la conduite de collecte 12 sont disjointes, placées à proximité l'une de l'autre, de manière à constituer ensemble le montant 3 support du tube chauffant 4.In this variant, the distribution pipe 11 and the collection pipe 12 are disjoint, placed close to each other, so as to constitute together the support upright of the heating tube 4.

Les conduites de distribution et de collecte peuvent être de section de forme variée, par exemple cylindrique, ovale ou rectangulaire. Pour des raisons esthétiques, elles sont placées de préférence à l'arrière des tubes chauffants 4 constituant la façade proprement dite du radiateur sèche-serviettes.The distribution and collection pipes may be of various shaped section, for example cylindrical, oval or rectangular. For aesthetic reasons, they are preferably placed at the rear of the heating tubes 4 constituting the actual facade of the towel radiator.

Comme représenté sur les figures 3 et 5, le tube chauffant 4 est une lame parallélépipédique, les orifices 5 et 7 ou 13 et 15 étant ménagés à des hauteurs différentes, à savoir les orifices d'arrivée 5 et 13 du fluide chaud sont placés plus hauts que les orifices de sortie 7 et 15 de manière à permettre la convection naturelle du fluide au sein du volume de la lame ; le fluide chaud pénètre dans la lame par l'orifice supérieur 5 ou 13, réchauffe la partie supérieure de la lame, puis descend vers la partie inférieure de la lame au fur et à mesure de son refroidissement et le fluide refroidi quitte la lame par l'orifice 7 ou 15.As shown on figures 3 and 5 , the heating tube 4 is a parallelepipedal blade, the orifices 5 and 7 or 13 and 15 being provided at different heights, namely the inlet orifices 5 and 13 of the hot fluid are placed higher than the outlet orifices 7 and So as to allow the natural convection of the fluid within the volume of the blade; the hot fluid enters the blade through the upper orifice 5 or 13, heats the upper part of the blade, then descends to the lower part of the blade as it cools and the cooled fluid leaves the blade by the orifice 7 or 15.

Ni le placement relatif des conduites de distribution et de collecte l'une par rapport à l'autre, ni leur positionnement par rapport à l'extrémité du tube chauffant n'est déterminant pour l'efficacité thermique du tube chauffant.Neither the relative placement of the distribution and collection lines relative to each other nor their positioning relative to the end of the heating tube is decisive for the thermal efficiency of the heating tube.

Les essais thermiques réalisés avec des radiateurs sèche-serviettes arborescents comportant des tubes chauffants 4 sous forme de lames et une conduite de distribution 11 du fluide chaud séparée de la conduite de collecte 12 du fluide refroidi sont présentés sur les figures 7 et 8.The thermal tests carried out with arbor-drying towel radiators comprising heating tubes 4 in the form of blades and a distribution duct 11 for the hot fluid separated from the collection duct 12 of the cooled fluid are presented on the Figures 7 and 8 .

La figure 7 est un radiateur de l'art antérieur dans lequel le fluide caloporteur est forcé à parcourir un trajet longitudinal à l'intérieur de chaque lame selon une direction prédéfinie et dans un seul sens. A cet effet, les extrémités distales des lames sont ici reliées entre elles par des tubes de connexion appelés "cigares" 20 de façon à forcer le fluide à parcourir une lame puis une lame adjacente avant de regagner la conduite de collecte.The figure 7 is a radiator of the prior art in which the coolant is forced to travel a longitudinal path within each blade in a predefined direction and in one direction. For this purpose, the distal ends of the blades are here interconnected by connection tubes called "cigars" 20 so as to force the fluid through a blade and an adjacent blade before returning to the collection line.

Dans le radiateur sèche-serviettes selon la présente invention, présenté à la figure 8, les tubes collecteurs "cigares" 20 sont absents et chaque lame est reliée, au niveau de l'une de ses extrémités, d'une part à la conduite de distribution 11 et d'autre part à la conduite de collecte 12.In the towel radiator according to the present invention, presented to the figure 8 , the "cigar" collecting tubes 20 are absent and each blade is connected, at one of its ends, on the one hand to the distribution pipe 11 and on the other hand to the collection pipe 12.

Des comparaisons ont été effectuées entre ces deux types de radiateur (les résultats sont schématisés sur les isothermes figures 7 et 8, les chiffres indiqués sont les températures relevées, exprimées en degrés Celsius).Comparisons were made between these two types of radiator (the results are schematized on the isotherms Figures 7 and 8 , the figures indicated are the temperatures recorded, expressed in degrees Celsius).

Le radiateur est à fonctionnement électrique, le fluide caloporteur est chauffé par une résistance chauffante disposée en partie inférieure de la conduite de distribution 11 et circule en circuit fermé dans l'ensemble du radiateur, formé par les tubes chauffants 4 et les conduites de distribution 11 et de collecte 12.The radiator is electrically operated, the heat transfer fluid is heated by a heating resistor arranged in the lower part of the distribution pipe 11 and circulates in a closed circuit throughout the radiator, formed by the heating tubes 4 and the distribution pipes 11 and collection 12.

Les diamètres des orifices, que ce soient des orifices d'entrée ou de sortie dans les tubes chauffants 4, et d'entrée ou de sortie des tubes de collecte, présentaient tous des diamètres identiques de 6 mm.The diameters of the orifices, whether inlet or outlet ports in the heating tubes 4, and inlet or outlet of the collection tubes, all had identical diameters of 6 mm.

Pour une puissance de 500 watts, il a été noté que la température maximale était de 75 °C alors que pour l'appareil de la figure 8, selon la présente invention, la température maximale atteinte était légèrement inférieure, à savoir de 72,1 °C.For a power of 500 watts, it was noted that the maximum temperature was 75 ° C whereas for the device of the figure 8 according to the present invention, the maximum temperature reached was slightly lower, namely 72.1 ° C.

Le ΔT, c'est-à-dire la différence de température entre le point le plus chaud et le point le plus froid dans des zones bien définies, mesurées à trois hauteurs différentes, selon le cahier des charges NF Electricité Performance Catégorie C du LCIE (Laboratoire Central des Industries Electriques) a révélé que ce ΔT était de 24 °C pour le radiateur selon l'art antérieur alors qu'il est de 19,9 °C pour l'appareil selon la présente invention.ΔT, ie the difference in temperature between the hottest point and the coldest point in well-defined zones, measured at three different heights, according to the NF Electricité Performance Category C specifications of LCIE (Central Laboratory of Electrical Industries) has revealed that this ΔT was 24 ° C for the radiator according to the prior art while it is 19.9 ° C for the apparatus according to the present invention.

Les temps de montée en température étaient de trois heures pour les deux appareils.The rise times were three hours for both devices.

On s'aperçoit donc que pour une même puissance, l'appareil selon la présente invention présente une température équivalente, voire plus homogène dans certains cas, comme visible sur les isothermes schématisées sur les figures 7 et 8.It can thus be seen that for the same power, the apparatus according to the present invention has a temperature that is equivalent, or even more homogeneous in certain cases, as visible on the schematic isotherms on the Figures 7 and 8 .

Dans un autre essai réalisé en comparant le même radiateur de l'art antérieur et le radiateur de la présente invention (présentés aux figures 7 et 8) pour lesquels les radiateurs sont reliés directement au réseau d'eau chaude de la maison, pour une puissance de 500 watts la température moyenne atteinte par le radiateur de l'art antérieur était de 53 °C et de 49 °C pour l'appareil selon la présente invention, c'est-à-dire une température légèrement inférieure assurant une meilleure sécurité pour l'usager.In another test carried out by comparing the same radiator of the prior art and the radiator of the present invention (shown in Figures 7 and 8 ) for which the radiators are directly connected to the hot water network of the house, for a power of 500 watts the average temperature reached by the radiator of the prior art was 53 ° C and 49 ° C for the apparatus according to the present invention, that is to say a slightly lower temperature ensuring better security for the user.

En ce qui concerne le temps de montée en température, il était de 12 minutes pour l'appareil de l'art antérieur alors qu'il est de 8 minutes seulement pour l'appareil selon la présente invention. On voit donc que le fluide caloporteur circule plus rapidement dans l'ensemble des tubes chauffants et permet une montée en température plus rapide qu'avec les radiateurs de l'art antérieur pour lesquels le fluide caloporteur est contraint de parcourir des trajets déterminés dans un sens ou dans l'autre du tube chauffant.As regards the rise time, it was 12 minutes for the apparatus of the prior art whereas it is only 8 minutes for the apparatus according to the present invention. It can therefore be seen that the coolant circulates more rapidly in all of the heating tubes and allows a faster rise in temperature than with the radiators of the prior art for which the heat transfer fluid is forced to traverse determined paths in one direction. or in the other of the heating tube.

Outre une simplification dans la construction des tubes chauffants qui sont donc tous identiques quel que soit leur position dans le radiateur, on obtient une homogénéisation plus rapide, notamment dans le cas des radiateurs reliés au chauffage central de l'habitation.In addition to a simplification in the construction of the heating tubes, which are therefore identical regardless of their position in the radiator, a faster homogenization is obtained, especially in the case of radiators connected to the central heating of the house.
