Description
Procedimiento de fabricación de un intercambiador de calor de placas apiladas provisto de un conducto by-pass e intercambiador obtenido mediante dicho procedimiento.Manufacturing procedure of a stacked plate heat exchanger provided with a conduit by-pass and exchanger obtained by means of said process.
La presente invención se refiere a un procedimiento de fabricación de un intercambiador de calor de placas apiladas provisto de un conducto by-pass. La invención también se refiere al intercambiador obtenido mediante dicho procedimiento.The present invention relates to a manufacturing procedure of a plate heat exchanger stacked provided with a by-pass duct. The invention also refers to the exchanger obtained by said procedure.
La invención se aplica especialmente a todo tipo de intercambiadores de calor dentro del ámbito del motor, especialmente se aplica a intercambiadores de recirculación de gases de escape de un motor (Exhaust Gas Recirculation Coolers o EGRC).The invention applies especially to all types of heat exchangers within the scope of the engine, especially applies to gas recirculation exchangers Exhaust of an engine (Exhaust Gas Recirculation Coolers or EGRC).
Una práctica bien establecida en el campo de la automoción consiste en proporcionar un sistema de recirculación de los gases de escape de un motor diesel, que se conoce como EGR o "Exhaust Gas Recycling", a fin de mezclar estos gases con el aire de admisión, puesto que la presencia de los gases de escape en la mezcla disminuye la producción de óxidos de nitrógeno (NOx).A well established practice in the field of automotive consists of providing a recirculation system of the exhaust gases of a diesel engine, which is known as EGR or "Exhaust Gas Recycling", in order to mix these gases with the intake air, since the presence of exhaust gases in The mixture decreases the production of nitrogen oxides (NOx).
Antes de ser mezclados con el aire de admisión, los gases de escape pueden ser enfriados en un intercambiador de calor (EGRC o "Exhaust Gas Recycling Cooler") instalado en el bucle del sistema EGR, al objeto de mejorar la eficiencia del sistema.Before being mixed with the intake air, Exhaust gases can be cooled in a heat exchanger heat (EGRC or "Exhaust Gas Recycling Cooler") installed in the EGR system loop, in order to improve the efficiency of the system.
En el bucle del sistema existe además una válvula (válvula EGR) que controla el paso de gases de escape a través del mismo.In the system loop there is also a valve (EGR valve) that controls the passage of exhaust gases to through it.
El intercambiador de calor propiamente dicho puede tener distintas configuraciones: por ejemplo, puede consistir en una carcasa tubular en cuyo interior se disponen una serie de tubos paralelos para el paso de los gases, circulando el refrigerante por la carcasa, exteriormente a los tubos; en otra realización, el intercambiador consta de una serie de placas paralelas que constituyen las superficies de intercambio de calor, de manera que los gases de escape y el refrigerante circulan entre dos placas, en capas alternadas.The heat exchanger itself it can have different configurations: for example, it can consist in a tubular housing inside which a series of parallel tubes for the passage of gases, circulating the refrigerant through the housing, externally to the tubes; in other embodiment, the exchanger consists of a series of plates parallel that constitute the heat exchange surfaces, so that the exhaust gases and the refrigerant circulate between two plates, in alternating layers.
En algunos casos, los sistemas EGR refrigerados presentan el inconveniente de que los gases de escape circulan por el intercambiador en cualquier condición de funcionamiento del motor a partir del momento en que se abre la válvula EGR: los gases son enfriados tanto cuando el motor está funcionando en régimen estable y su temperatura es elevada, como durante un arranque en frío, cuando la temperatura de los gases es muy inferior.In some cases, refrigerated EGR systems they have the disadvantage that the exhaust gases circulate through the exchanger in any engine operating condition from the moment the EGR valve opens: the gases are cooled both when the engine is running steady and its temperature is high, as during a cold start, when the temperature of the gases is much lower.
Este enfriamiento de los gases cuando su temperatura no es elevada representa un inconveniente desde el punto de vista medioambiental, puesto que incrementa el nivel de emisiones de CO y de hidrocarburos y además conlleva generación de ruido.This gas cooling when your temperature is not high represents an inconvenience from the point of environmental view, since it increases the level of CO and hydrocarbon emissions and also involves generation of noise.
Para solucionar este problema, se utiliza al menos un conducto en derivación, integrado en el intercambiador, adecuado para hacer circular los gases de escape sin que sufran un enfriamiento sustancial. El conducto en derivación, que se puede denominar simplemente "by-pass", permite minimizar el enfriamiento de los gases de escape en algunas situaciones de funcionamiento del motor, por ejemplo arranque en frío, en que su temperatura no es elevada y su enfriamiento sería perjudicial para la emisión de contaminantes.To solve this problem, it is used at minus a bypass duct, integrated into the exchanger, suitable for circulating the exhaust gases without suffering a substantial cooling The bypass duct, which can be simply called "by-pass", allows minimize the cooling of exhaust gases in some engine operating situations, for example starting in cold, in which its temperature is not high and its cooling would be harmful for the emission of pollutants.
El sistema puede comprender una válvula de regulación o by-pass que selecciona el recorrido de los gases de escape a través del intercambiador o a través del conducto by-pass.The system may comprise a valve regulation or by-pass that selects the path of the exhaust gases through the exchanger or through the bypass duct.
Dicho conducto by-pass puede estar integrado de manera interna o externa. Un conducto by-pass interno está situado dentro de la carcasa del intercambiador y está rodeado por el refrigerante. Las pérdidas de potencia durante el modo by-pass son mayores que para un by-pass externo.Said bypass pass can be integrated internally or externally. A conduit internal bypass is located inside the housing of the exchanger and is surrounded by the refrigerant. The losses power during bypass mode are greater than for an external bypass.
El procedimiento de fabricación más habitual de un conducto by-pass externo es mediante hidroformación, debido a la necesidad de incluir un tramo de ondas que permite reducir las dilataciones térmicas entre las zonas refrigeradas y las no refrigeradas.The most common manufacturing procedure for an external by-pass duct is by hydroforming, due to the need to include a stretch of waves which allows to reduce the thermal expansion between the zones refrigerated and non-refrigerated.
La mayoría de los intercambiadores EGR provistos de conducto by-pass conocidos son del tipo que utilizan haz de tubos paralelos. En el caso de intercambiadores de placas apiladas, no se conoce ninguna aplicación con tubo by-pass externo, como circuito de bajo rendimiento.Most of the EGR exchangers provided known by-pass ducts are of the type that They use parallel tube bundle. In the case of exchangers stacked plates, no tube application known external bypass, as bass circuit performance.
Las principales características asociadas a la adición de un conducto by-pass a un intercambiador de calor EGR son:The main characteristics associated with the adding a by-pass conduit to an exchanger EGR heat are:
- Necesidad de un componente adicional: un conducto by-pass externo es necesario para realizar el circuito de bajo rendimiento.- Need for an additional component: a External by-pass duct is necessary to perform The low performance circuit.
- Alto coste: la necesidad de tramos de ondas en el conducto by-pass debido a las dilataciones térmicas producidas dentro del intercambiador, obliga a que este conducto deba ser fabricado mediante hidroformación, y además esto se da específicamente para cada aplicación. La hidroformación es una tecnología muy cara tanto en las herramientas utilizadas como en la producción.- High cost: the need for wave stretches in the by-pass duct due to dilations thermal produced inside the exchanger, forces that this duct must be manufactured by hydroforming, and also this It is given specifically for each application. Hydroforming is a very expensive technology both in the tools used and in the production.
- Baja estandarización: la hidroformación no es un proceso flexible; por tanto, es necesario desarrollar una nueva herramienta y un nuevo conducto para cada aplicación.- Low standardization: hydroforming is not a flexible process; therefore, it is necessary to develop a new tool and a new conduit for each application.
El objetivo del procedimiento de fabricación de un intercambiador de calor de placas apiladas provisto de un conducto by-pass de la presente invención es solventar los inconvenientes que presentan los procedimientos conocidos en la técnica, proporcionando un procedimiento de fabricación más sencillo y con un menor coste de producción.The purpose of the manufacturing process of a stacked plate heat exchanger provided with a by-pass duct of the present invention is solve the problems presented by the procedures known in the art, providing a method of Simpler manufacturing and lower production cost.

- e)and)
- soldar en horno el conjunto del intercambiador ensamblado.bake the whole assembled exchanger.
De este modo, se obtiene un conducto by-pass que está integrado con las propias placas apiladas, con lo cual no resulta necesario añadir un conducto by-pass para cada aplicación. Se obtiene una reducción en el coste de producción y además se mejora la estandarización del intercambiador.In this way, a conduit is obtained by-pass that is integrated with the plates themselves stacked, so it is not necessary to add a conduit by-pass for each application. You get a reduction in the cost of production and also improves standardization of the exchanger.
Preferentemente, las al menos dos placas se corresponden con una placa superior y una placa inferior de refuerzo del conjunto de placas apiladas.Preferably, the at least two plates are correspond to an upper plate and a lower reinforcement plate of the set of stacked plates.
De acuerdo con una realización de la presente invención, la estampación de cada parte del conducto by-pass, realizado durante la etapa b), se lleva a cabo dejando una zona libre sin material, de modo que durante la etapa d) de ensamblaje del conjunto se procede a colocar un tramo de ondas en dicha zona libre de material del conducto by-pass.In accordance with an embodiment of the present invention, stamping of each part of the duct by-pass, carried out during stage b), takes out leaving a free zone without material, so that during the step d) of assembly assembly, a section of waves in said free zone of duct material by-pass
En este caso, para formar el conducto by-pass entero es necesario añadir únicamente el tramo de ondas, que puede ser estándar para la mayor parte de aplicaciones.In this case, to form the duct entire bypass is necessary to add only the stretch of waves, which can be standard for most of Applications.
Preferentemente, el tramo de ondas se coloca en una zona central del conducto by-pass. Cabe destacar que el tramo de ondas también puede ser colocado en cualquier otra zona del conducto by-pass.Preferably, the wave section is placed in a central zone of the by-pass duct. It should be noted that the stretch of waves can also be placed in any other by-pass duct area.
De acuerdo con otra realización de la presente invención, la estampación de cada parte del conducto by-pass, realizado durante la etapa b), se lleva a cabo formando además una zona de ondas estampada como parte integrante del conducto by-pass.In accordance with another embodiment of the present invention, stamping of each part of the duct by-pass, carried out during stage b), takes cape also forming a stamped wave zone as part member of the by-pass duct.

Haciendo referencia a la figura 1, el intercambiador de calor 1 de tipo EGR comprende una pluralidad de placas apiladas 2 entre las cuales circulan los gases de escape a refrigerar y el líquido refrigerante entre dos placas 2, en capas alternadas, incluyendo una placa superior 3 y una placa inferior 4, pozos de entrada 5 y salida 6 del líquido refrigerante, una entrada 7 y una salida 8 de los gases a refrigerar, y medios de conexión de la entrada 9 y salida 10 de gases con la línea de recirculación. El intercambiador 1 también incluye un conducto by-pass externo 11, adecuado para hacer circular el fluido refrigerante sin que sufra un enfriamiento sustancial. Dicho conducto by-pass 11 incluye un tramo central con ondas 12 para absorber las dilataciones térmicas.Referring to figure 1, the EGR type heat exchanger 1 comprises a plurality of stacked plates 2 between which the exhaust gases circulate at refrigerate and the coolant between two plates 2, layered alternating, including an upper plate 3 and a lower plate 4, inlets 5 and outlet 6 of the coolant, one inlet 7 and an outlet 8 of the gases to be cooled, and connection means of the inlet 9 and outlet 10 of gases with the recirculation line.

Saying by-pass duct 11 includes a central section with 12 waves to absorb thermal expansion.
El intercambiador 1 también comprende una válvula de regulación (no representada) que regula el camino que recorrerá el flujo de gases a través del intercambiador 1, es decir, a través de las correspondientes placas 2, o bien preferentemente a través del conducto by-pass 11, dependiendo de la temperatura de los gases de escape.The exchanger 1 also comprises a regulating valve (not shown) that regulates the path that will travel the flow of gases through exchanger 1, that is, through the corresponding plates 2, or preferably to through the by-pass duct 11, depending on the exhaust gas temperature.
El procedimiento de fabricación del intercambiador de calor 1 de placas apiladas de la presente invención, consiste en realizar las siguientes etapas:The manufacturing process of heat exchanger 1 of stacked plates of the present invention consists in performing the following steps:
En primer lugar, se procede a obtener dos placas, superior 3 e inferior 4, provistas cada una de una superficie adicional 11a, 11b en uno de sus lados.First, we proceed to obtain two plates, upper 3 and lower 4, each provided with a additional surface 11a, 11b on one of its sides.
En siguiente lugar, se procede a estampar dichas placas superior 3 e inferior 4, moldeando al mismo tiempo en cada superficie adicional una mitad 11a, 11b del conducto by-pass 11. La estampación de cada mitad 11a, 11b del conducto by-pass 11, se lleva a cabo dejando una zona libre 13 sin material. Cada superficie adicional 11a, 11b se corresponde con la mitad del conducto by-pass 11, excluyendo el tramo de ondas 12.Next, we proceed to stamp these upper 3 and lower 4 plates, molding at the same time on each additional surface one half 11a, 11b of the duct by-pass 11. Stamping of each half 11a, 11b of the by-pass duct 11, is carried out leaving a free zone 13 without material. Each additional surface 11a, 11b is corresponds to half of the bypass pass 11, excluding the stretch of waves 12.
A continuación, se procede a estampar el resto de placas 2 que serán apiladas posteriormente.Then, the rest is stamped of plates 2 that will be stacked later.
La estampación se realiza mediante una herramienta de estampación convencional provista de un módulo adicional para crear las correspondientes mitades 11a, 11b del conducto by-pass 11. Cabe destacar que este módulo no se utiliza para estampar el resto de placas apiladas 2.Stamping is done by a conventional stamping tool provided with a module additional to create the corresponding halves 11a, 11b of the by-pass duct 11. It should be noted that this module it is not used to stamp the rest of stacked plates 2.
En siguiente lugar, se procede a ensamblar el conjunto de placas apiladas 2 entre ambas placas superior 3 e inferior 4, de modo que las dos mitades 11a, 11b del conducto by-pass 11 quedan unidas entre sí, añadiendo al mismo tiempo el tramo de ondas 12 en dicha zona libre de material 13 del conducto by-pass 11 (ver figura 1). Dicho tramo de ondas 12 puede ser mantenido en posición mediante la presión efectuada por la herramienta de estampación.Next, we proceed to assemble the set of stacked plates 2 between both upper plates 3 e bottom 4, so that the two halves 11a, 11b of the duct by-pass 11 are joined together, adding to the same time the stretch of waves 12 in said material free zone 13 of the by-pass duct 11 (see figure 1).
