Description
La présente invention concerne un corps de chauffe destiné à uneThe present invention relates to a heating element intended for a
installation de chauffage central, renfermant un fluide chaud s'écoulant entre un raccord central heating system, containing a hot fluid flowing between a fitting
d'alimentation et un raccord de retour. power supply and a return fitting.
Les corps de chauffe consistent aujourd'hui généralement en une construction soudée comportant deux tuyaux collecteurs destinés à l'alimentation et au retour, auxquels sont raccordés plusieurs tuyaux plats reliés transversalement entre eux. Les différents éléments de raccordement sont soudés et même les tuyaux doivent être fermés par soudage aux extrémités. Afin de pouvoir purger le corps de chauffe, il est prévu en règle générale, à chaque raccord entre les tuyaux plats et les tuyaux collecteurs, deux éléments de raccordement superposés. Lors de la fabrication d'un tel corps de chauffe, les travaux de soudure et les contr8les ultérieurs de tous les cordons de soudure, de pression, etc. représentent dès lors une part très élevée dans les coûts de production. De plus, du point de vue des coûts 20 de fabrication, l'intervention d'une main d'oeuvre spécialisée est indispensable pour réaliser les travaux de soudure. Jusqu'à présent, il a toujours été estimé qu'un corps de chauffe de ce type devait pouvoir être Today, the heating bodies generally consist of a welded construction comprising two collecting pipes for feeding and return, to which are connected several flat pipes connected transversely to one another. The various connection elements are welded and even the pipes must be closed by welding at the ends. In order to be able to purge the heating body, there is generally provided, at each connection between the flat pipes and the collector pipes, two superimposed connection elements. During the manufacture of such a heating body, welding work and subsequent controls of all weld seams, pressure, etc. therefore represent a very high share of production costs. In addition, from the point of view of manufacturing costs, the intervention of a specialized workforce is essential to carry out the welding work. So far, it has always been felt that a heating element of this type should be able to be
purgé. A cet effet, des mesures particulières sont 25 généralement prévues. purge. For this purpose, particular measures are generally provided.
L'objet de la présente invention est de réduire principalement les coûts de fabrication d'un corps de chauffe et, dans cette optique, de renoncer entièrement au système particulièrement coûteux de construction 30 soudée. A cet effet, le corps de chauffe suivant l'invention est constitué d'au moins un tuyau continu reliant le raccord d'alimentation au raccord de retour, courbé plusieurs fois dans le même sens d'enroulement suivant un centre, de manière à former un serpentin. Le 35 corps de chauffe suivant l'invention est destiné à être intégré dans une installation de chauffage central pour locaux d'habitation, sera aussi plat que possible et occupera un volume limité, le plus souvent de forme rectangulaire, par exemple sous un appui de fenêtre. Les 5 formes de construction préférées permettent de satisfaire à de telles exigences tant au niveau encombrement que du The object of the present invention is to reduce mainly the costs of manufacturing a heating body and, in this view, to completely abandon the particularly expensive system of welded construction. For this purpose, the heating body according to the invention consists of at least one continuous pipe connecting the supply connection to the return fitting, bent several times in the same direction of winding along a center, so as to form a coil. The heating body according to the invention is intended to be integrated into a central heating installation for living quarters, will be as flat as possible and occupy a limited volume, most often of rectangular shape, for example under a support of window. The preferred forms of construction make it possible to satisfy such requirements both in terms of size and
point de vue esthétique.aesthetic point of view.
Outre l'avantage d'être très simple et peu coQteux à fabriquer, le corps de chauffe suivant l'invention offre également l'avantage de ne requérir aucune opération de purge ni de dispositifs particuliers de purge, étant donné que l'air éventuellement présent In addition to the advantage of being very simple and inexpensive to manufacture, the heating body according to the invention also offers the advantage of not requiring any purging operation or particular purging devices, since the air possibly present
est véhiculé par le fluide circulant dans le tuyau. is conveyed by the fluid flowing in the pipe.
Contrairement à un corps de chauffe soudé, il n'existe 15 aucun espace perdu. Dans les installations actuelles de chauffage dites à basse température, le fluide chaud, lequel est de préférence de l'eau chaude, s'écoule à une vitesse assez élevée dans le tuyau, de sorte qu'une faible inertie thermique et une meilleure transmission de 20 chaleur peuvent être obtenues avec un tel corps de chauffe, par rapport à un corps de chauffe présentant un tuyau de section supérieure. Il en résulte une meilleure Unlike a welded heating body, there is no lost space. In current low-temperature heating installations, the hot fluid, which is preferably hot water, flows at a relatively high velocity into the pipe, so that a low thermal inertia and a better transmission of heat are achieved. Heat can be obtained with such a heating body, with respect to a heating body having an upper section pipe. This results in a better
utilisation de l'énergie à mettre en oeuvre. use of the energy to be used.
L'invention sera mieux comprise et d'autres buts, caractéristiques, détails et avantages de celle-ci The invention will be better understood and other purposes, features, details and advantages thereof
apparaîtront plus clairement au cours de la description explicative qui va suivre faite en référence aux dessins schématiques annexés donnés uniquement à titre d'exemple illustrant plusieurs modes de réalisation de l'invention 30 et dans lesquels: will become more apparent in the following explanatory description with reference to the accompanying schematic drawings given by way of example only, illustrating several embodiments of the invention and in which:
- la figure i est une représentation schématique d'un corps de chauffe vu de face; - la figure 2 est une vue de côté du corps de chauffe suivant la figure 1; - les figures 3, 3a, 4 et 5 montrent des divers corps de chauffe suivant la figure 1, présentant différentes formes de contour; et - la figure 6 est une autre forme de construction du corps de chauffe, avec une double ligne - Figure i is a schematic representation of a heater seen from the front; - Figure 2 is a side view of the heater according to Figure 1; - Figures 3, 3a, 4 and 5 show the various heating bodies according to Figure 1, having different contour shapes; and - Figure 6 is another form of construction of the heating body, with a double line
de tubes en spirale.of spiral tubes.
Le corps de chauffe i suivant les figures 1 et 2 est constitué d'un tuyau 4 continu reliant le raccord d'alimentation 2 au raccord de retour 3, courbé plusieurs 10 fois dans le même sens d'enroulement suivant un centre 5, de manière à former un serpentin. En tant que spirale, le tuyau 4 comporte des spires situées dans le même plan, s'écartant progressivement du centre 5 et présentant un contour de forme substantiellement rectangulaire ou ovale. On obtient ainsi un corps de chauffe 1 de forme généralement rectangulaire ou ovale, vu de face. Le corps de chauffe est dès lors extrêmement plat et possède une The heating element i according to FIGS. 1 and 2 consists of a continuous pipe 4 connecting the supply coupling 2 to the return fitting 3, bent several times in the same direction of winding along a center 5, in such a way that to form a coil. As a spiral, the pipe 4 comprises turns located in the same plane, progressively diverging from the center 5 and having a contour of substantially rectangular or oval shape. This gives a heating body 1 of generally rectangular or oval shape, seen from the front. The heating body is therefore extremely flat and has a
profondeur correspondant au diamètre du tuyau 4. depth corresponding to the diameter of the pipe 4.
L'espace non rempli par les spires du tuyau 4 20 au centre 5 de la spirale peut être occupé par une plaque 6, laquelle est représentée aux figures 3 à 6, sur laquelle peut alors être avantageusement installée la vanne du corps de chauffe, laquelle n'est pas représentée au dessin. Comme le montrent ces figures, l'extrémité 7 25 du tuyau se trouvant à l'extérieur de la spirale peut être courbée vers l'intérieur et être ramenée vers la The space not filled by the turns of the pipe 4 at the center 5 of the spiral can be occupied by a plate 6, which is shown in FIGS. 3 to 6, on which the valve of the heating body can then advantageously be installed. is not shown in the drawing. As shown in these figures, the end 25 of the pipe outside the spiral can be bent inwards and brought back to the
plaque 6, derrière les spires situées dans le même plan. plate 6 behind the turns in the same plane.
Les figures 3 à 5 montrent clairement qu'il est possible de donner au corps de chauffe 1 présentant uns 30 contour de forme substantiellement rectangulaire, en fonction du type de courbure du tuyau 4, n'importe quelle forme extérieure souhaitée, o les extrémités opposées du corps de chauffe peuvent être de forme droite ou semi-circulaire. Un corps de chauffe de forme rectangulaire peut être installé comme illustré au dessin ou FIGS. 3 to 5 clearly show that it is possible to give the heating body 1 having a substantially rectangular shaped contour, depending on the type of curvature of the pipe 4, any desired external shape, o the opposite ends the heating body may be straight or semi-circular. A rectangular shaped heating element can be installed as shown in the drawing or
dressé verticalement, en le faisant tourner de 900. upright, turning it 900.
Dans le corps de chauffe représenté à la figure 3a, les deux tuyaux 4a et 4b forment une spirale double, In the heating body shown in FIG. 3a, the two pipes 4a and 4b form a double spiral,
o les spires d'une spirale et celles de l'autre spirale se suivent tour à tour depuis le centre vers l'extérieur. o The turns of a spiral and those of the other spiral follow each other from center to outward.
Une extrémité des tuyaux 4a et 4b est reliée à un raccord d'alimentation 2 commun et l'autre extrémité desdits tuyaux est reliée à un raccord de retour 3 commun. Les deux spirales peuvent se trouver dans le même plan ou dans des plans parallèles l'un à l'autre. Suivant le même principe, plusieurs spirales, c'est-à-dire plus de deux One end of the pipes 4a and 4b is connected to a common supply connection 2 and the other end of said pipes is connected to a common return fitting 3. The two spirals can be in the same plane or in parallel planes to each other. Following the same principle, several spirals, that is to say more than two
spirales, disposées dans des plans différents, sont 15 également possibles. spirals, arranged in different planes, are also possible.
Les spirales suivant les figures i à 5 possèdent un centre à partir duquel le tuyau d'alimentation ou le tuyau de retour doit être ramené dans un deuxième plan derrière la ligne de tubes formant 20 la spirale, vers l'extérieur de la spirale. Le corps de chauffe suivant la figure 6 ne possède pas ce désavantage. Dans ce corps de chauffe 10, une double ligne de tubes consistant en un tuyau 11 continu forme une spirale caractérisée en ce qu'une ligne de tubes est 25 solidaire de l'autre ligne de tubes en 12, représentant le milieu dudit tuyau 11. Dans ce type de construction, le tuyau formant l'ensemble du corps de chauffe se trouve dans un seul plan, y compris les extrémités 13 et 14 de raccordement servant à l'alimentation et au retour. Une telle structure est avantageuse du point de vue technique de fabrication étant donné qu'il n'est pas nécessaire de courber le tuyau dans un deuxième plan et représente également une solution optimale du point de vue esthétique. Outre les exemples de réalisation représentés, un corps de chauffe de ce type peut bien entendu être également fabriqué de manière à présenter un contour de forme non rectangulaire, par exemple un contour de forme trapézoidale ou en losange, lorsqu'on souhaite lui donner une forme particulière ou l'installer dans une niche de forme irrégulière. Toutes les autres formes s'écartant de celle présentée à la figure 1 peuvent être réalisées en coudant le tuyau suivant un angle autre que 900 et en 10 faisant varier les- dimensions des sections droites du tuyau. L'avantage particulier du corps de chauffe suivant l'invention se situe au niveau des coûts de fabrication, lesquels sont substantiellement inférieurs à 15 ceux des corps de chauffe traditionnels. La fabrication d'un corps de chauffe suivant l'invention permet une économie de matière de 15 à 20% et une économie de main d'oeuvre de 40 à 50%. Un tel corps de chauffe possède une résistance à la pression pouvant atteindre 100 bars, étant donné qu'il est seulement constitué d'un tuyau. De plus, il est aisé à purger entièrement lorsqu'on prévoit avantageusement une vanne de réglage d'usage courant à l'alimentation, un petit robinet d'arrêt au retour et une soupape de purge légèrement en amont du robinet d'arrêt. 25 Pendant l'opération de remplissage, la vanne de réglage et la soupape de purge sont ouvertes, tandis que le robinet d'arrêt se trouve fermé. Dès que l'eau sort de la soupape de purge, celle-ci est fermée et le robinet The spirals according to Figs. 1 to 5 have a center from which the feed pipe or the return pipe is to be returned to a second plane behind the line of spiral tubes, outwardly of the spiral. The heater according to Figure 6 does not have this disadvantage. In this heating body 10, a double line of tubes consisting of a continuous pipe 11 forms a spiral characterized in that a line of tubes is integral with the other line of tubes at 12, representing the middle of said pipe 11. In this type of construction, the pipe forming the whole of the heating body is in a single plane, including the ends 13 and 14 of connection for supply and return. Such a structure is advantageous from the technical point of view of manufacture since it is not necessary to bend the pipe in a second plane and also represents an optimal solution from the aesthetic point of view. In addition to the exemplary embodiments shown, a heating body of this type can of course also be manufactured so as to have a non-rectangular shaped contour, for example a contour of trapezoidal or diamond shape, when it is desired to give it a shape. particular or install it in a niche of irregular shape. All other forms deviating from that shown in FIG. 1 can be made by bending the pipe at an angle other than 900 and varying the dimensions of the straight sections of the pipe. The particular advantage of the heating body according to the invention lies in manufacturing costs, which are substantially lower than those of traditional heating bodies. The manufacture of a heating body according to the invention allows a saving of material of 15 to 20% and a labor saving of 40 to 50%. Such a heater has a pressure resistance of up to 100 bar, since it consists only of a hose. In addition, it is easy to purge entirely when advantageously provided a control valve of current use to the power supply, a small return stopcock and a purge valve slightly upstream of the stopcock. During the filling operation, the control valve and the purge valve are open, while the stopcock is closed. As soon as the water comes out of the purge valve, it is closed and the valve
d'arrêt est ouvert. Le corps de chauffe se trouve alors 30 rempli et entièrement purgé. stop is open. The heating body is then filled and completely purged.
