Description

Unidad de radiador para plantas de calefacción.Radiator unit for plants heating.

La presente invención se refiere a una unidad de radiador bimetálico según se define en el preámbulo de la reivindicación 1 para plantas de calefacción, realizada sin soldaduras. Dicho radiador se conoce, por ejemplo, a partir del documento EP-A1-0481154. En comparación con la técnica anterior conocida, la invención consigue una reducción considerable en los costes de fabricación y también una mayor resistencia a la corrosión en las bocas de las tuberías verticales. Dichas mejoras que se van a obtener utilizando un cuerpo estructural que forma la tubería vertical consisten en una pieza estirada de aluminio en cuyo canal interior se inserta a presión una tubería de acero de la misma longitud. Por otra parte, para formar dicha unidad de radiador se proporcionan dos cuerpos de aleación de aluminio, que se realizarán por fundición a presión, en forma de tuberías horizontales que tienen tuberías verticales que se extienden en sentido descendente para insertarse axialmente en la parte extrema de los canales de las piezas interpuestas estiradas de aluminio. La unidad de radiador se va a formar a presión ensamblando las tres partes con un bloqueo axial de las tuberías verticales que se extienden en sentido descendente dentro de las bocas de los canales interiores de los cuerpos centrales. A partir de la solicitud de patente europea nº 96830380.0 se conoce un tratamiento que consiste en el moldeo de un núcleo tubular de acero que se formará para soldar los extremos aplanados de dos tramos paralelos de tuberías con las partes extremas convergiendo simétricamente hacia el exterior. Dicho núcleo de acero se colocará sobre unos ejes en un molde de fundición a presión para obtener, con la formación de la parte de cubrición en aleación de aluminio, un cuerpo bimetálico preliminar de tratamiento en el que se aplicarán los siguientes tratamientos en la línea de alimentación. En primer lugar, en dichos tratamientos entran en funcionamiento un par de unidades cortadoras. Dichas unidades cortadoras, que avanzan hacia las tuberías horizontales, actúan sobre los bordes de las tuberías para eliminar las partes extremas salientes del núcleo tubular. A continuación, en segundo lugar, se realiza un moleteado en las bocas interiores de las tuberías para retirar los residuos. Finalmente, se realizan las roscas en las bocas externas para permitir el ensamblaje de las unidades utilizando piezas roscadas conocidas colocadas a modo de empalmes de tuberías interiores de las tuberías horizontales. El tratamiento citado anteriormente, que produce los radiadores actuales conocidos con una mayor fiabilidad desde el punto de vista de la fabricación, presenta los inconvenientes de unos costes elevados de la materia prima y unos costes elevados del tratamiento mientras que, desde el punto de vista de la utilización, la presencia de dos materiales con diferentes coeficientes de corrosión, conectados con las bocas interiores de las tuberías horizontales, tales como el acero de las tuberías verticales y la aleación de aluminio de la cubrición de fundición a presión, determina por rebose la formación de ranuras que actúan como factores de frenado del flujo y de descomposición de dicho radiador. Otro sistema de fabricación, según se describe y muestra en la solicitud de patente italiana BO97A 000336, da a conocer la colocación en un molde de fundición a presión de un cuerpo de aluminio preliminar de tratamiento en el que se incluye longitudinalmente un conducto de acero para la tubería vertical. Dicho segundo sistema permite una reducción importante de los costes de fabricación realizando un tipo nuevo de tubería vertical con solamente un canal y llega a eliminar tanto el primer tratamiento para formar el núcleo con tramos paralelos de tubería como el siguiente tratamiento de corte y moleteado aunque, desde el punto de vista de la utilización, presenta los mismos convenientes del sistema descrito en la solicitud de patente europea nº 96830380.0. Se debe señalar que la tecnología actual en este sector considera irracional la utilización de acero para realizar tanto las tuberías horizontales como las verticales por los costes elevados y por los inconvenientes resultantes de las infiltraciones que tienen lugar en las partes de soldadura y de la utilización inadecuada de solamente un tramo de conducto de acero para formar las bocas interiores de las tuberías horizontales. Esto, debido al hecho de una corrosión diferenciada de las partes bimetálicas, en lugar de actuar como un refuerzo del cuerpo, acelera su descomposición. La presente invención crea una unidad nueva de radiador que tiene un refuerzo estructural en las bocas interiores de las tuberías formando una estructura compuesta coaxial que resulta de la instalación de las tuberías verticales que se extienden en sentido descendente desde las tuberías horizontales hacia las bocas de las tuberías verticales. Por otra parte, la unidad de radiador realizada permite una reducción elevada de los costes de la materia prima y una reducción de los costes de tratamiento ya que consigue una unidad de radiador que se formará simplemente ensamblando tres partes. De entre dichas tres partes, dos en aleación de aluminio, que se realizarán por fundición a presión, en forma de tuberías horizontales, reduciendo considerablemente la parte que se realizará por prensado en caliente, mientras que la tercera parte consiste en una pieza estirada de aluminio, que se obtendrá por corte a partir de un producto semielaborado, y determina la menor resistencia a la corrosión de la tubería vertical, asignada al aluminio, lo cual se evita mediante la instalación de una tubería de acero en su canal interior. La unidad de radiador nueva se formará por medio de una única fase de ensamblaje. La unidad de radiador inventada se formará ensamblando tres partes preestablecidas: a) un cuerpo de formación de matriz superior con la parte envolvente 1 en forma de una tubería horizontal 5 con unas aletas 2 y 3 de difusión en oposición, unos sectores salientes de formación inferior, presentando dicha tubería 5 en sus extremos unas bocas roscadas 4 y presentando dos aberturas en forma de tuberías verticales 6 que se extienden en sentido descendente con unas partes rebajadas 8 en los extremos de sus paredes 7; b) un par de cuerpos 9 de piezas estiradas de aluminio, que se colocarán en interposición, que comprenden unos canales interiores 10 en los cuales se insertan tuberías 11 de acero; c) un cuerpo de formación de matriz inferior con la parte envolvente 12 en forma de una tubería horizontal 5 con unas aletas 13 y 14 de difusión en oposición, unos sectores salientes de formación superior, presentando dicha tubería 5 en sus extremos unas bocas roscadas 4 y presentando dos aberturas en forma de tuberías verticales 6 que se extienden en sentido descendente con unas partes rebajadas 16 en los extremos de sus paredes 15. Una vez colocados en posición los tres cuerpos citados, la unidad de radiador se formará a presión con únicamente una fase de ensamblaje que determina la inserción de las partes rebajadas 8 y 16 de las tuberías verticales 6 en las bocas de los canales interiores 10 del par de cuerpos 9 de aluminio en los que se insertan las tuberías 11 de acero. Por otra parte, en este ensamblaje, la estabilización viene dada por los sectores salientes de los dos pares de aletas 2, 3 y 13, 14 de difusión que acaban conteniendo las partes extremas del cuerpo 9 de aluminio. Cada cuerpo interpuesto 9 se formará a partir de una pieza estirada de aluminio y con la inserción a presión de una tubería 11 de acero de la misma longitud dentro de su tubería 10 de canal. En una segunda realización, la unidad de radiador se forma con una parte envolvente superior 1 y con una parte envolvente inferior 12 que tienen tres aletas 2, 3 y 13, 14 de difusión, extendiéndose en sentido descendente tres canales verticales 6 con las partes rebajadas 8 y 16. Los tres cuerpos separados y la unidad de radiador final se ilustran en los dibujos de las páginas 1, 2, 3, 4, 5, 6, 7 y 8.

In Compared to the known prior art, the invention achieves a considerable reduction in manufacturing costs and also increased corrosion resistance in pipe mouths vertical These improvements that will be obtained using a body structural that forms the vertical pipe consist of a piece stretched aluminum in whose inner channel a pressure is inserted steel pipe of the same length. Moreover, to form said radiator unit two alloy bodies of aluminum, which will be made by die casting, in the form of horizontal pipes that have vertical pipes that are extend downwards to insert axially in the extreme part of the channels of the stretched interposed pieces of aluminum. The radiator unit is going to form under pressure by assembling the three parts with an axial blockage of the vertical pipes that they extend downwards within the mouths of the inner channels of the central bodies. From the European patent application No. 96830380.0 a treatment is known consisting of the molding of a tubular steel core that will form to weld the flattened ends of two parallel sections of pipes with the end parts converging symmetrically outward. Said steel core will be placed on some axes in a die casting mold to obtain, with the formation of the aluminum alloy covering part, a bimetallic body Preliminary treatment in which the following will be applied treatments in the feeding line. First, in said treatments come into operation a couple of cutting units. Said cutting units, which advance towards the pipes horizontal, they act on the edges of the pipes to eliminate the protruding end portions of the tubular core. Then in second, a knurling is done in the inner mouths of the pipes to remove the waste. Finally, the threads on the outer mouths to allow the assembly of the units using known threaded parts placed as a Inner pipe joints of horizontal pipes. The treatment cited above, which produces the radiators current acquaintances with greater reliability from the point of view of manufacturing, has the disadvantages of costs high raw material and high treatment costs while, from the point of view of use, the presence of two materials with different coefficients of corrosion, connected to the inner mouths of the pipes horizontal, such as the steel of the vertical pipes and the die casting aluminum alloy, determines by overflow the formation of grooves that act as braking factors of the flow and decomposition of said radiator. Another manufacturing system, as described and shown in the Italian patent application BO97A 000336, discloses the placement in a die casting mold of a body of preliminary treatment aluminum which is included longitudinally a steel conduit for the vertical pipe. Said second system allows a significant reduction in costs of manufacturing making a new type of vertical pipe with only one channel and gets to eliminate both the first treatment to form the core with parallel sections of pipe such as the following cutting and knurling treatment though, from the point of view of the use, presents the same advantages of system described in European Patent Application No. 96830380.0. It should be noted that current technology in this sector considers irrational the use of steel to make both pipes horizontal as vertical due to high costs and inconveniences resulting from the infiltrations that take place in welding parts and improper use of only a section of steel conduit to form the inner mouths of Horizontal pipes This, due to the fact of corrosion differentiated from bimetallic parts, instead of acting as a body reinforcement, accelerates its decomposition. The present invention creates a new radiator unit that has a booster structural in the inner mouths of the pipes forming a coaxial composite structure that results from the installation of vertical pipes that extend downward from horizontal pipes to the mouths of the pipes vertical Moreover, the radiator unit made allows a high reduction in raw material costs and a reduction of treatment costs since it achieves a unit of radiator that will be formed simply by assembling three parts. From between said three parts, two in aluminum alloy, which made by die casting, in the form of pipes horizontal, greatly reducing the part to be performed hot pressing, while the third part consists of a stretched piece of aluminum, which will be obtained by cutting from of a semi-finished product, and determines the lowest resistance to corrosion of the vertical pipe, assigned to aluminum, which is avoid by installing a steel pipe in its channel inside. The new radiator unit will be formed by means of a Single assembly phase. The invented radiator unit will be formed assembling three preset parts: a) a training body upper die with the enclosure part 1 in the form of a pipe horizontal 5 with fins 2 and 3 diffusion in opposition, some outgoing sectors of lower formation, presenting said pipe 5 at its ends threaded mouths 4 and presenting two openings in the form of vertical pipes 6 that extend in the direction descending with recessed parts 8 at the ends of their walls 7; b) a pair of bodies 9 of stretched aluminum parts, which will be placed in interposition, which comprise channels interiors 10 in which steel pipes 11 are inserted; c) a lower die forming body with the enveloping part 12 in shape of a horizontal pipe 5 with fins 13 and 14 of dissemination in opposition, outgoing training sectors upper, said pipe 5 presenting at its ends mouths threaded 4 and presenting two openings in the form of pipes vertical 6 extending downward with parts recessed 16 at the ends of its walls 15. Once placed in position the three bodies mentioned, the radiator unit will be formed under pressure with only one assembly phase that determines the insertion of the recessed parts 8 and 16 of the vertical pipes 6 in the mouths of the inner channels 10 of the pair of bodies 9 of aluminum in which the steel pipes 11 are inserted. For other part, in this assembly, stabilization is given by protruding sectors of the two pairs of fins 2, 3 and 13, 14 of diffusion that end up containing the extreme parts of the body 9 of aluminum. Each interposed body 9 will be formed from one piece stretched out of aluminum and with the pressure insertion of a pipe 11 of steel of the same length inside its channel pipe 10. In a second embodiment, the radiator unit is formed with a upper envelope part 1 and with a lower envelope part 12 which have three fins 2, 3 and 13, 14 diffusion, extending in downstream three vertical channels 6 with the parts recesses 8 and 16. The three separate bodies and the radiator unit final are illustrated in the drawings on pages 1, 2, 3, 4, 5, 6, 7 and 8.
