Description
La présente invention est relative à une installation de chauffage central munie d'un circuit d'eau chaude à usage domestique ou eau sanitaire et comprenant un appareil de chauffage comportant une enveloppe ou virole, dont la partie inférieure est munie d'un brûleur, notamment d'un brûleur à gaz et sur laquelle vient s'enrouler ou non un conduit dans lequel circule l'eau du circuit de chauffage, ce circuit traverse ensuite un faisceau d'ailettes situées à la partie supérieure de l'enveloppe sur la trajectoire des gaz chauds qui s'échappent de cette dernière pour être dirigés ensuite vers une conduite d'évacuation.The present invention relates to a central heating installation provided with a hot water circuit for domestic use or sanitary water and comprising a heating device comprising an envelope or ferrule, the lower part of which is provided with a burner, in particular of a gas burner and on which is wound or not a conduit in which the water circulates from the heating circuit, this circuit then crosses a bundle of fins located at the upper part of the envelope on the trajectory of the hot gases escaping from the latter to then be directed to a discharge pipe.
Le brevet européen EP-A-0329508 (priorité brevet français FR-A-2627266) décrit une installation de chauffage central dans laquelle l'échangeur est mixte. Il comprend principalement un ensemble de tubes servant au chauffage de l'eau sanitaire, conformés en épingle ou serpentin qui sont disposés à l'intérieur de tubes aplatis. Lesdits tubes forment un bloc relié par des coudes et un ensemble d'ailettes, ils constituent le circuit de l'eau de chauffage, l'eau sanitaire étant réchauffée par ladite eau.European patent EP-A-0329508 (priority French patent FR-A-2627266) describes a central heating installation in which the exchanger is mixed. It mainly comprises a set of tubes used for heating domestic water, shaped as a pin or coil which are arranged inside flattened tubes. Said tubes form a block connected by elbows and a set of fins, they constitute the heating water circuit, the sanitary water being heated by said water.
Cette configuration assure que les tubes du circuit d'eau chaude sanitaire, disposés en épingle ou serpentin dans les tubes aplatis du circuit d'eau de chauffage ne sont pas au contact de ces derniers.This configuration ensures that the tubes of the domestic hot water circuit, arranged in a pin or coil in the flat tubes in the heating water circuit are not in contact with them.
Les dimensions desdits tubes aplatis et desdits tubes sont choisies de manière que le volume d'eau contenu entre les tubes aplatis et les méandres des tubes en épingle soit aussi réduit que possible.The dimensions of said flattened tubes and of said tubes are chosen so that the volume of water contained between the flattened tubes and the meanders of the hairpin tubes is as small as possible.
Cette disposition oblige à avoir à chaque extrémité des embouts brasés ou soudés afin d'obturer le circuit de chauffage ainsi que des coudes servant à relier les circuits respectifs entre eux.This arrangement requires having at each end brazed or welded end pieces to close off the heating circuit as well as elbows used to connect the respective circuits together.
Elle présente quelques inconvénients graves, d'une part il est difficile et peu économique de réaliser des soudures ou des brasures étanches, et d'autre part le métal d'apport possède une tenue mécanique et chimique moindre que le cuivre dont sont constitués les tubes. L'espérance de vie de ces échangeurs mixtes s'en trouve réduite en cas de détartrage périodique.It has some serious drawbacks, on the one hand it is difficult and uneconomical to make welds or tight solders, and on the other hand the filler metal has less mechanical and chemical resistance than the copper from which the tubes are made. . The life expectancy of these mixed exchangers is reduced in the event of periodic descaling.
La présente invention se propose d'apporter une installation perfectionnée ne présentant pas les inconvénients mentionnés ci-dessus.The present invention proposes to provide an improved installation which does not have the drawbacks mentioned above.
Elle a donc pour objet une installation de chauffage central munie d'un circuit d'eau chaude à usage domestique ou eau sanitaire qui comprend un appareil de chauffage comportant une virole dont la partie intérieure est munie d'un brûleur ; notamment d'un brûleur à gaz et sur laquelle vient s'enrouler ou non un conduit du circuit de chauffage qui traverse ensuite un faisceau d'ailettes situées à la partie supérieure de la virole, sur le trajet des gaz chauds, le circuit de chauffage dans sa traversée du faisceau d'ailettes étant réalisé sous la forme d'une pluralité de tubes aplatis, raccordés les uns aux autres par des coudes et le circuit d'eau chaude sanitaire étant réalisé sous la forme d'une série de tubes conformés en épingle, reliés entre eux par des coudes, lesdits tubes sanitaires étant disposés à l'intérieur des tubes aplatis concernant le circuit de chauffage, caractérisée en ce que :
- les tubes du serpentin sanitaire possèdent une forme d'épingle, ledit serpentin comporte une portion de tube cintré dans une direction à 90° dans un plan vertical puis une autre à 90° de la précédente et ainsi de suite,
- ledit serpentin comprend une série consécutive de portions de tubes cintrés dans deux plans perpendiculaires et sans soudure,
- la réunion à l'une des extrémités communes de l'ensemble constitué par le circuit d'eau sanitaire conformé en épingle et les tubes aplatis du circuit d'eau de chauffage est réalisée par un collecteur qui est monté sur ces derniers dits tubes ; ce collecteur étant lui-même obturé par un couvercle .
- the tubes of the sanitary coil have a pin shape, said coil comprises a portion of tube bent in a direction at 90 ° in a vertical plane then another at 90 ° from the previous one and so on,
- said coil comprises a consecutive series of portions of tubes bent in two perpendicular and seamless planes,
- the meeting at one of the common ends of the assembly constituted by the sanitary water circuit shaped as a pin and the flattened tubes of the heating water circuit is produced by a collector which is mounted on the latter said tubes; this collector itself being closed by a cover.
D'autres caractéristiques et avantages de cette invention ressortiront de la description faite ci-après en référence aux dessins annexés qui en illustrent des exemples de réalisation dépourvus de tout caractère limitatif.Other characteristics and advantages of this invention will emerge from the description given below with reference to the appended drawings which illustrate exemplary embodiments thereof without any limiting character.
La Figure 1 est une vue en perspective globale de l'ensemble représentant en éclaté les différents constituants de l'échangeur mixte A.Figure 1 is an overall perspective view of the assembly exploded exploding the various constituents of the mixed exchanger A.
La Figure 2 est une vue en perspective des tubes conformés en une série d'épingles dans deux plans perpendiculaires deux à deux.Figure 2 is a perspective view of the tubes shaped into a series of pins in two perpendicular planes two by two.
La Figure 3 est une vue plane de l'ensemble de l'échangeur mixte A.Figure 3 is a plan view of the assembly of the mixed exchanger A.
La Figure 4 est une vue plane en élévation latérale de l'échangeur mixte A.Figure 4 is a plan view in side elevation of the mixed exchanger A.
La Figure 5 est une vue plane en élévation frontale en cours de montage de l'échangeur mixte A.Figure 5 is a plan view in front elevation during assembly of the mixed exchanger A.
Selon un exemple préféré de réalisation de cet échangeur mixte, on dispose, à l'intérieur de ce bloc de tubes aplatis, un ensemble de tubes conformés en épingle, utilisés pour le circuit d'eau chaude sanitaire. L'échangeur mixte est conformé de manière à ce que:
- les dimensions desdits tubes aplatis et desdits tubes du serpentin d'eau sanitaire sont choisies de manière que le volume d'eau compris dans l'espace annulaire entre le corps et les épingles soit aussi réduit que possible;
- le bloc échangeur consiste en une multitude de plaques enfilées et brasées sur les tubes de chauffage aplatis. Ces dits tubes sont reliés à une de leurs extrémités par des coudes élaborés par cintrage de ces dits tubes formant une épingle et sans soudure.
- the dimensions of said flattened tubes and of said tubes of the domestic water coil are chosen so that the volume of water included in the annular space between the body and the pins is as small as possible;
- the heat exchanger block consists of a multitude of plates threaded and brazed onto the flattened heating tubes. These said tubes are connected at one of their ends by elbows produced by bending these said tubes forming a pin and seamless.
En se référant aux dessins et notamment aux Figures 1, 2, 3 et 4, on voit que l'appareil de chauffage, objet de cette invention, comporte un premier conduit pour le chauffage de l'eau du circuit du chauffage central et un second conduit pour le chauffage de l'eau sanitaire.Referring to the drawings and in particular to Figures 1, 2, 3 and 4, it can be seen that the heater, object of this invention, comprises a first conduit for heating the water of the central heating circuit and a second duct for heating domestic water.
On aperçoit (cf Figure 1) le circuit d'eau sanitaire conformé en une série d'épingles 1 inclus à l'intérieur des tubes aplatis 2 du circuit de chauffage, eux aussi conformés en épingle.We can see (see Figure 1) the sanitary water circuit shaped as a series of pins 1 included inside the flattened tubes 2 of the heating circuit, also shaped as pins.
Dans la partie supérieure de l'appareil de chauffage où est positionné l'objet de l'invention, le conduit du circuit de chauffage se présente sous la forme d'une série d'épingles de tubes aplatis tels que 2 qui présentent chacun une section droite de forme ovale, le plus grand axe étant horizontal. Ces tubes sont raccordés à l'une de leurs extrémités par des coudes obtenus par cintrage de ces dits tubes.In the upper part of the heating appliance where the object of the invention is positioned, the duct of the heating circuit is in the form of a series flattened tube pins such as 2 which each have a cross section of oval shape, the largest axis being horizontal. These tubes are connected at one of their ends by elbows obtained by bending these said tubes.
Le conduit d'eau sanitaire est constitué d'un tube, de préférence de section droite circulaire, disposé à l'intérieur des tubes aplatis 2 du circuit de chauffage, conformés en une série d'épingles obtenues par cintrage de ce dit tube dans deux plans perpendiculaires deux à deux. On augmente ainsi la surface d'échange thermique entre les deux circuits de l'échangeur mixte puisque tous les cintrages se trouvent dans le circuit de chauffage et non à l'extérieur.The sanitary water pipe consists of a tube, preferably of circular cross section, placed inside the flattened tubes 2 of the heating circuit, shaped into a series of pins obtained by bending this said tube in two perpendicular planes two by two. This increases the heat exchange surface between the two circuits of the mixed exchanger since all the bends are in the heating circuit and not outside.
Le positionnement des tubes du circuit sanitaire conformés en épingle disposées à l'intérieur des tubes aplatis du circuit de chauffage est réalisé de manière qu'il n'existe aucun contact physique entre les parois des tubes 1 et 2, et de manière que le volume d'eau contenu dans l'espace annulaire résiduel soit le plus petit possible. Il résulte aussi de cette configuration que toutes les calories véhiculées par le circuit de chauffage sont transférées dans le circuit d'eau sanitaire. L'assemblage respectif des sous-ensembles constitutifs est le suivant : les tubes 1 conformés en épingle du circuit d'eau sanitaire, munis des bagues en plastique 6, s'insèrent à l'intérieur des tubes aplatis 2 du circuit d'eau de chauffage, tandis que les ailettes 3 et le collecteur 4 s'enfilent sur les tubes aplatis 2 du circuit de chauffage, le couvercle 5 obturant complètement l'ensemble. Ce collecteur garantit le cheminement du fluide de chauffage ainsi que l'étanchéité de l'ensemble.The positioning of the pin-shaped sanitary circuit tubes arranged inside the flattened tubes of the heating circuit is carried out so that there is no physical contact between the walls of the tubes 1 and 2, and so that the volume of water contained in the residual annular space is as small as possible. It also results from this configuration that all the calories conveyed by the heating circuit are transferred into the sanitary water circuit. The respective assembly of the constituent sub-assemblies is as follows: the tubes 1 shaped as a hairpin of the sanitary water circuit, provided with plastic rings 6, are inserted inside the flattened tubes 2 of the water circuit of heating, while the fins 3 and the manifold 4 thread on the flattened tubes 2 of the heating circuit, the
Ce collecteur 4 assure le maintien des deux circuits de l'échangeur. Il est brasé sur le circuit d'eau de chauffage.This collector 4 maintains the two circuits of the exchanger. It is brazed on the heating water circuit.
Deux cloisons 7 obligent l'eau de chauffage à circuler en série dans les tubes aplatis. Ce collecteur sera lui-même obturé par un couvercle 5 garantissant l'étanchéité.Two partitions 7 force the heating water to circulate in series in the flattened tubes. This collector will itself be closed by a
Dans la variante représentée sur la Figure 3, on peut enfiler sur l'ensemble des tubes du circuit sanitaire des bagues en matière plastique résistant à la chaleur et à l'humidité, de préférence en silicone ; ces bagues étant enfilées sur le tube 1 à intervalles réguliers. Cette disposition particulière présente un double avantage ; elle permet tout d'abord d'éviter tout contact des tubes 1 avec les tubes aplatis 2 constituant le circuit de chauffage, et d'autre part elle élimine les vibrations d'origine hydraulique qui se produisent dans ce type d'installation lorsque l'eau sanitaire circule dans la série d'épingles.In the variant shown in Figure 3, one can thread on all the tubes of the sanitary circuit rings of plastic material resistant to heat and humidity, preferably silicone; these rings being threaded on the tube 1 at regular intervals. This particular arrangement has a double advantage; it first of all makes it possible to avoid any contact of the tubes 1 with the flattened tubes 2 constituting the heating circuit, and on the other hand it eliminates the vibrations of hydraulic origin which occur in this type of installation when the sanitary water circulates in the series of pins.
La lecture de la description qui précède montre que l'invention apporte une installation de chauffage assurant un échange thermique parfait entre les deux circuits incorporés d'eau de chauffage et d'eau sanitaire grâce à une surface d'échange thermique importante obtenue par la configuration en épingle des différents circuits.Reading the above description shows that the invention provides a heating installation ensuring perfect heat exchange between the two incorporated circuits of heating water and sanitary water thanks to a large heat exchange surface obtained by the configuration. the different circuits.
L'absence de coudes rapportés sur chacun des circuits, les changements de direction étant obtenus par cintrage des tubes des différents circuits, simplifie le mode de fabrication de l'échangeur, plus de brasure ni de soudure et évite les risques de fuites.The absence of added bends on each of the circuits, the changes of direction being obtained by bending the tubes of the different circuits, simplifies the method of manufacturing the exchanger, no more soldering or soldering and avoids the risks of leaks.
