Description
Procedimiento de fabricación de un tubo para la conducción de un fluido de un intercambiador de calor, y tubo obtenido mediante dicho procedimiento.Manufacturing procedure of a tube for conduction of a fluid from a heat exchanger, and tube obtained by said procedure.
La presente invención se refiere a un procedimiento de fabricación de un tubo para la conducción de un fluido de un intercambiador de calor. La invención también se refiere al tubo obtenido mediante dicho procedimiento.The present invention relates to a manufacturing procedure of a tube for the conduction of a fluid from a heat exchanger. The invention is also refers to the tube obtained by said procedure.
La invención se aplica especialmente en intercambiadores de recirculación de gases de escape de un motor (EGRC).The invention is especially applied in Exhaust gas recirculation exchangers of an engine (EGRC).
En algunos intercambiadores de calor para el enfriamiento de gases, por ejemplo los utilizados en sistemas de recirculación de los gases de escape hacia la admisión de un motor de explosión (sistemas denominados "Exhaust Gas Recirculation" o EGR), los gases circulan por un haz de tubos paralelos alojados en una carcasa, y durante esta circulación son enfriados por intercambio térmico con un fluido de refrigeración que se hace circular en el interior de la carcasa, exteriormente a los tubos de paso de los gases.In some heat exchangers for the gas cooling, for example those used in recirculation of the exhaust gases towards the intake of an engine explosion (systems called "Exhaust Gas Recirculation" or EGR), the gases circulate through a bundle of parallel tubes housed in a housing, and during this circulation they are cooled by thermal exchange with a cooling fluid that is made circulate inside the housing, externally to the pipes passage of gases.
Son conocidos tubos de gas de sección rectangular apropiados para ser encajados de manera optimizada dentro de la carcasa de un intercambiador de sección rectangular. Dichos tubos de sección rectangular son fabricados a partir de un tubo circular y también pueden presentar corrugaciones con el fin de mejorar el rendimiento térmico del intercambiador de calor. Generalmente dichas corrugaciones se extienden a lo largo de la longitud del tubo, pero sin llegar a alcanzar el radio del tubo, es decir, los extremos circulares del mismo que no han sido conformados.Section gas tubes are known rectangular suitable to be optimally fitted inside the casing of a rectangular section exchanger. Said rectangular section tubes are manufactured from a circular tube and can also present corrugations in order to improve the heat efficiency of the heat exchanger. Generally said corrugations extend along the tube length, but without reaching the radius of the tube, it is say the circular ends of it that have not been conformed
Actualmente, el único método conocido para poder mecanizar las corrugaciones a lo largo de la longitud del tubo en su totalidad es mediante un proceso de hidroformado.Currently, the only known method to be able to machining the corrugations along the length of the tube in its entirety is through a hydroforming process.
El procedimiento de fabricación de este tipo de tubos es el siguiente:The manufacturing process of this type of tubes is as follows:
En primer lugar, se parte de un tubo liso de sección circular, el cual ha sido obtenido a partir de una lámina doblada y soldada. A continuación, el tubo se somete a un proceso de hidroformado que incluye dos etapas: primero se procede a conformar el tubo que pasará de tener una sección circular a una sección sensiblemente rectangular, y después se efectúan las corrugaciones. Finalmente, se efectúa el corte de los extremos del tubo y el desbarbado, en caso necesario.First, it starts from a smooth tube of circular section, which has been obtained from a sheet bent and welded. Then the tube undergoes a process hydroforming that includes two stages: first proceed to form the tube that will go from having a circular section to a substantially rectangular section, and then the corrugations Finally, the cutting of the ends of the tube and deburring, if necessary.
No obstante este procedimiento de fabricación del citado tubo presenta los siguientes inconvenientes:Notwithstanding this manufacturing procedure The said tube has the following drawbacks:
- El coste del procedimiento de fabricación es elevado debido a la combinación de diversos procesos. Por una parte, el tubo doblado y soldado usado como materia primaria ya posee un valor añadido; por otra parte, el proceso de hidroformado tiene bajas cadencias ya que no es un proceso continuo; y además requiere inversiones elevadas puesto que las máquinas y herramientas son considerablemente caras.- The cost of the manufacturing procedure is elevated due to the combination of various processes. By a part, the bent and welded tube used as primary material already it has an added value; on the other hand, the hydroforming process It has low rates since it is not a continuous process; plus it requires high investments since the machines and Tools are considerably expensive.
- El material de desecho del procedimiento de fabricación es elevado porque durante el proceso de hidroformado es necesario tener una zona de sección circular en los extremos del tubo, donde los cilindros de la máquina de hidroformado serán colocados para sellar e inyectar el líquido a elevada presión. Por tanto, estas zonas de sección circular deben ser eliminadas para obtener la forma final del tubo.- Waste material from the procedure of manufacturing is high because during the hydroforming process it is it is necessary to have a circular section area at the ends of the tube, where the cylinders of the hydroforming machine will be placed to seal and inject the liquid at high pressure. By therefore, these circular section zones must be removed to Get the final shape of the tube.
El objetivo del procedimiento de fabricación de un tubo para la conducción de un fluido de un intercambiador de calor de la presente invención es solventar los inconvenientes que presentan los procedimientos conocidos en la técnica, proporcionando un procedimiento de fabricación de los tubos con un coste menor.The purpose of the manufacturing process of a tube for the conduction of a fluid from an exchanger of heat of the present invention is to solve the drawbacks that present the procedures known in the art, providing a manufacturing process for the tubes with a lower cost
El procedimiento de fabricación de un tubo para la conducción de un fluido de un intercambiador de calor, objeto de la presente invención, siendo dicho tubo del tipo que presenta una sección transversal sensiblemente rectangular, formado por dos paredes opuestas de mayor anchura y dos paredes redondeadas de menor anchura, se caracteriza por el hecho de que consiste en realizar las siguientes etapas:The manufacturing process of a tube for the conduction of a fluid from a heat exchanger, object of the present invention, said tube being of the type presenting a substantially rectangular cross section, formed by two opposite walls of greater width and two rounded walls of smaller width, is characterized by the fact that it consists of perform the following stages:
- a)to)
- Partiendo de una lámina metálica, realizar una pluralidad de corrugaciones mediante un proceso de estampación;Starting from a metal sheet, perform a plurality of corrugations through a process of stamping
- b)b)
- Realizar el doblado de la lámina mediante un proceso de estampación o de conformado; yFold the sheet through a stamping or forming process; Y
- c)C)
- Proceder a soldar los bordes libres para cerrar el tubo, considerando las tolerancias requeridas.Proceed to weld the free edges to close the tube, considering the tolerances required
De este modo, se obtiene un procedimiento de fabricación que implica la combinación en una línea de producción de tres tecnologías diferentes: estampación de las corrugaciones, doblado y soldadura.In this way, a procedure of manufacturing that involves the combination in a production line of three different technologies: corrugation stamping, bending and welding.
Opcionalmente, después de la etapa c) se procede a cortar los extremos finales del tubo, si es necesario.Optionally, after stage c) proceed to cut the end ends of the tube, if necessary.
Las principales ventajas que se obtienen mediante el procedimiento de la invención son:The main advantages obtained By the method of the invention they are:
- --
- Una reducción de los costes de producción debido a que el proceso es continuo, y en consecuencia, las cadencias obtenidas son más elevadas que las obtenidas con el proceso de hidroformado del tubo.A reduction of production costs because the process is continuous, and consequently, the rates obtained are more higher than those obtained with the hydroforming process of tube.
- --
- Una reducción del material de desecho debido a que con este procedimiento no es necesario disponer de más cantidad de material ya que basta solamente 1 mm por cada lado para llevar a cabo los puntos de soldadura, y no como ocurría en el caso de la hidroformado donde se necesitaba al menos 14 mm.A reduction of waste material because with this procedure is not necessary to have more material since only 1 mm per side is enough to carry out the welding points, and not as was the case with the hydroforming where at least 14 mm was needed.
- --
- La capacidad de producción obtenida es más elevada.The Production capacity obtained is higher.
- --
- Una menor cantidad de inversiones ya que la máquina y las herramientas son más baratas que las utilizadas para el tubo realizado mediante hidroformado.A lower amount of investments since the machine and tools they are cheaper than those used for the tube made by hydroformed
- --
- El espacio requerido en la planta industrial es menor.He Required space in the industrial plant is smaller.
Preferentemente, las corrugaciones se estampan en aquellas zonas de la lámina metálica correspondientes a las paredes opuestas de mayor anchura del tubo una vez montado, llegando a alcanzar parte de las paredes redondeadas de menor anchura.Preferably, the corrugations are stamped in those areas of the metal sheet corresponding to the opposite walls of greater width of the tube once mounted, reaching part of the smaller rounded walls width.
