Description

INTERCAMBIADOR DE CALOR PARA GASES, EN ESPECIAL DE LOS GASES DE ESCAPE DE UN MOTOR HEAT EXCHANGER FOR GASES, ESPECIALLY OF EXHAUST GASES OF AN ENGINE

La presente invención se refiere a un intercambiador de calor para gases, en especial de los gases de escape de un motor. La invención se aplica especialmente en intercambiadores de recirculación de gases de escape de un motor (EGRC). The present invention relates to a heat exchanger for gases, especially the exhaust gases of an engine. The invention is especially applied in one-engine exhaust gas recirculation exchangers (EGRC).

ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION

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, los dos medios que intercambian calor están separados por una pared. In some heat exchangers for cooling gases, for example those used in exhaust gas recirculation systems towards the admission of an explosion engine, the two means that exchange heat are separated by a wall.

La configuración actual de los intercambiadores EGR en el mercado se corresponde con un intercambiador de calor metálico fabricado generalmente de acero inoxidable o aluminio. The current configuration of the EGR exchangers on the market corresponds to a metal heat exchanger generally made of stainless steel or aluminum.

Básicamente, hay dos tipos de intercambiadores de calor EGR: un primer tipo consiste en una carcasa en cuyo interior se dispone un haz de tubos paralelos para el paso de los gases, circulando el refrigerante por la carcasa, exteriormente a los tubos, y el segundo tipo 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, pudiendo incluir aletas para el mejorar el intercambio de calor. Basically, there are two types of EGR heat exchangers: a first type consists of a housing in whose interior there is a parallel tube beam for the passage of gases, the refrigerant circulating through the housing, externally to the tubes, and the second The type consists of a series of parallel plates that constitute the heat exchange surfaces, so that the exhaust gases and the refrigerant circulate between two plates, in alternating layers, and may include fins to improve heat exchange.

En el caso de intercambiadores de calor de haz de tubos, la unión entre los tubos y la carcasa puede ser de diferentes tipos. Generalmente, los tubos están fijados por sus extremos entre dos placas de soporte acopladas en cada extremo de la carcasa, presentando ambas placas de soporte una pluralidad de orificios para la colocación de los respectivos tubos. In the case of tube beam heat exchangers, the connection between the tubes and the housing can be of different types. Generally, the tubes are fixed at their ends between two support plates coupled at each end of the housing, both support plates having a plurality of holes for the placement of the respective tubes.

Dichas placas de soporte están fijadas a su vez a unos medios de conexión con la línea de recirculación, que pueden consistir en una conexión en V o bien en un reborde periférico de conexión o brida, dependiendo del diseño de la línea de recirculación donde está ensamblado el intercambiador. El reborde periférico puede estar ensamblado junto con un depósito de gas, de manera que el depósito de gas es una pieza intermedia entre la carcasa y el reborde, o bien el reborde puede estar ensamblado directamente a la carcasa. Said support plates are in turn fixed to connection means with the recirculation line, which may consist of a V-connection or a peripheral connection flange or flange, depending on the design of the recirculation line where it is assembled. the exchanger The peripheral flange may be assembled together with a gas tank, so that the gas tank is an intermediate piece between the housing and the flange, or the flange may be assembled directly to the housing.

En ambos tipos de intercambiadores EGR, la mayor parte de sus componentes son metálicos, de modo que están ensamblados por medios mecánicos y después soldados en horno o soldados por arco o láser para asegurar una adecuada estanqueidad requerida para esta aplicación. En algunos casos, también pueden incluir algunos componentes de plástico, que pueden tener una sola función o varias funciones integradas en una única pieza. In both types of EGR exchangers, most of its components are metallic, so that they are assembled by mechanical means and then welded in an oven or welded by arc or laser to ensure adequate sealing required for this application. In some cases, they may also include some plastic components, which may have a single function or several functions integrated into a single piece.

La función principal de los intercambiadores EGR es el intercambio de calor entre los gases de escape y el fluido refrigerante, con el fin de enfriar los gases. Adicionalmente, el intercambiador EGR debe satisfacer otras funciones secundarias tales como ser ensamblado al bloque motor, proporcionar la conexión al fluido refrigerante, o proporcionar la conexión al circuito de gases de escape, entre otras. Actualmente, los diferentes componentes del intercambiador están unidos a la carcasa mediante soldadura en horno o soldadura por arco o láser. The main function of the EGR exchangers is the exchange of heat between the exhaust gases and the cooling fluid, in order to cool the gases. Additionally, the EGR exchanger must fulfill other secondary functions such as being assembled to the engine block, providing the connection to the cooling fluid, or providing the connection to the exhaust gas circuit, among others. Currently, the different components of the exchanger are attached to the housing by means of furnace welding or arc or laser welding.

Algunos intercambiadores EGR de tubos o de placas existentes en el mercado incluyen deflectores, los cuales están ubicados dentro del circuito de fluido refrigerante. El diseño y número de deflectores puede variar de una aplicación a otra, en función de las necesidades de su uso y de las restricciones del fabricante de vehículos, en cuanto a condiciones de funcionamiento o restricciones de empaquetado del intercambiador. Some existing tube or plate EGR exchangers include baffles, which are located within the refrigerant fluid circuit. The design and number of baffles may vary from one application to another, depending on the needs of its use and the restrictions of the vehicle manufacturer, in terms of operating conditions or packaging restrictions of the exchanger.

En la mayoría de los casos, los deflectores son usados con la finalidad de mejorar la circulación del fluido refrigerante alrededor de los tubos de los gases, evitando así puntos de estancamiento que podrían causar la ebullición del fluido refrigerante dentro del intercambiador, y mejorar la refrigeración de todos los tubos para obtener un mejor rendimiento del intercambiador. In most cases, the baffles are used in order to improve the circulation of the refrigerant fluid around the gas pipes, thus avoiding stagnation points that could cause the boiling of the refrigerant fluid inside the exchanger, and improve cooling of all the tubes to obtain a better performance of the exchanger.

En otros casos, la razón para incluir algunos deflectores es evitar problemas mecánicos que pueden aparecer bajo las condiciones de trabajo del intercambiador en el motor. In other cases, the reason for including some baffles is to avoid mechanical problems that may appear under the working conditions of the exchanger in the engine.

Es conocido un intercambiador EGR que utiliza un deflector longitudinal que divide el interior de la carcasa en dos mitades para direccionar a modo de by-pass el fluido refrigerante desde una mitad de la carcasa a la otra mitad cuando los conductos de entrada y salida del fluido refrigerante están situados en el mismo lado de la carcasa. Dicho deflector está fijado a la carcasa del intercambiador mediante puntos de soldadura y presenta una longitud algo menor que la longitud de la carcasa. It is known an EGR exchanger that uses a longitudinal baffle that divides the interior of the housing into two halves to bypass the cooling fluid from one half of the housing to the other half when the fluid inlet and outlet ducts refrigerants are located on the same side of the housing. Said deflector is fixed to the exchanger housing by welding points and has a length somewhat smaller than the length of the housing.

La solicitud de patente española nº 200931016, todavía no publicada, del mismo titular que la presente solicitud, comprende una pluralidad de deflectores dispuestos transversalmente a lo largo del interior de la carcasa. Cada deflector tiene una superficie menor que la superficie transversal de la carcasa por lo que permite el paso parcial del fluido refrigerante. Dichos deflectores no están dispuestos de manera alineada sino que están colocados Spanish patent application No. 200931016, not yet published, of the same holder as the present application, comprises a plurality of baffles arranged transversely along the inside of the housing. Each baffle has a smaller surface area than the transverse surface of the housing, thus allowing partial passage of the cooling fluid. Said baffles are not arranged in an aligned manner but are placed

5 alternadamente entre sí, quedando las zonas de paso de fluido refrigerante distribuidas alternadamente, por lo que se asegura una correcta distribución del fluido refrigerante, a la vez que se mejora la resistencia mecánica ante vibraciones. Además dichos deflectores están fijados a la carcasa mediante soldadura en horno. 5 alternately with each other, leaving the refrigerant fluid passage areas distributed alternately, so that a correct distribution of the refrigerant fluid is ensured, while improving the mechanical resistance to vibrations. Furthermore, said baffles are fixed to the housing by oven welding.

Las patentes JP2000292089 y JP2000283666 incluyen una pluralidad de deflectores transversales a modo de Patents JP2000292089 and JP2000283666 include a plurality of transverse baffles by way of

10 placas dispuestos en el interior de una carcasa de sección circular. El diseño de dichos deflectores es muy similar a la configuración de las placas de soporte situadas en ambos extremos de la carcasa, siendo el diámetro de dichos deflectores igual al diámetro interior de la carcasa, e incluyen unas aberturas para permitir el paso de fluido refrigerante a su través. Las posiciones de dichas aberturas de paso en los diferentes deflectores están distribuidas alternadamente. 10 plates arranged inside a circular section housing. The design of said deflectors is very similar to the configuration of the support plates located at both ends of the housing, the diameter of said deflectors being equal to the internal diameter of the housing, and include openings to allow the passage of cooling fluid to through The positions of said passage openings in the different baffles are alternately distributed.

15 En general, el uso de deflectores dentro de los intercambiadores de calor está en aumento y es más frecuente durante los últimos años teniendo en cuenta la normativa medioambiental y las restricciones de diseño de algunos tipos de intercambiadores, tales como: 15 In general, the use of baffles within heat exchangers is on the rise and is more frequent in recent years, taking into account environmental regulations and design restrictions of some types of heat exchangers, such as:

20 - Intercambiadores de calor que permiten el uso de dos circuitos de fluido refrigerante, incluso si se trata del mismo fluido o no. 20 - Heat exchangers that allow the use of two refrigerant fluid circuits, even if it is the same fluid or not.

--
Intercambiadores de calor que deben enfriar dos fluidos calientes, incluso si se trata del mismo fluido o no. Heat exchangers that must cool two hot fluids, even if it is the same fluid or not.

25 - Intercambiadores de calor que tienen los conductos de entrada y salida de fluido refrigerante en el mismo lado de la carcasa. 25 - Heat exchangers that have the coolant inlet and outlet ducts on the same side of the housing.

El principal problema que presenta el uso de deflectores es asegurar una estanqueidad adecuada entre los dos circuitos definidos dentro de la carcasa del intercambiador cuando se usan diferentes fluidos refrigerantes, lo cual The main problem with the use of baffles is to ensure adequate tightness between the two defined circuits inside the exchanger housing when different cooling fluids are used, which

30 está relacionado con la manera de ensamblar y fijar dicho deflector dentro de la carcasa, generalmente mediante puntos de soldadura, respetando a su vez el comportamiento mecánico que el intercambiador debe cumplir requerido por las especificaciones del fabricante de vehículos. 30 is related to the way of assembling and fixing said deflector inside the housing, generally by welding points, while respecting the mechanical behavior that the exchanger must meet as required by the vehicle manufacturer's specifications.

Otro problema que presenta este tipo de deflectores es poder asegurar la posición y orientación adecuadas del 35 deflector cuando es ensamblado dentro de la carcasa antes de ser soldado. Another problem with this type of deflectors is to be able to ensure the proper position and orientation of the deflector when it is assembled inside the housing before being welded.

40 presente invención es solventar los inconvenientes que presentan los intercambiadores conocidos en la técnica, proporcionando un deflector destinado a mejorar la distribución de un fluido refrigerante que circula dentro del intercambiador, o incluso separar dos fluidos refrigerantes diferentes sin comunicación entre ellos dentro de una misma carcasa, permitiendo un ensamblaje más eficaz de dicho deflector en el interior del intercambiador. The present invention is to solve the disadvantages of the exchangers known in the art, by providing a baffle designed to improve the distribution of a refrigerant fluid circulating within the exchanger, or even separate two different refrigerant fluids without communication between them within the same housing. , allowing a more efficient assembly of said deflector inside the exchanger.

45 El intercambiador de calor para gases, en especial de los gases de escape de un motor, objeto de la presente invención, es del tipo que comprende un haz de tubos dispuestos en el interior de una carcasa, destinados a la circulación de los gases con intercambio de calor con al menos un flujo de fluido refrigerante, estando dichos tubos fijados por sus extremos entre dos placas de soporte acopladas en cada extremo de la carcasa, y medios de desviación dispuestos en el interior de la carcasa susceptibles de direccionar el al menos un flujo de fluido The heat exchanger for gases, especially the exhaust gases of an engine, object of the present invention, is of the type comprising a bundle of tubes arranged inside a housing, intended for the circulation of gases with heat exchange with at least one flow of refrigerant fluid, said tubes being fixed at their ends between two support plates coupled at each end of the housing, and bypass means arranged inside the housing capable of directing the at least one fluid flow

50 refrigerante dentro de la carcasa, y se caracteriza por el hecho de que los medios de desviación comprenden un deflector longitudinal sensiblemente paralelo al haz de tubos, destinado a dividir la carcasa en dos circuitos, estando dicho deflector fijado por sus bordes longitudinales a las paredes internas de la carcasa y por sus bordes transversales a sendas placas de soporte mediante soldadura. 50 refrigerant inside the housing, and is characterized by the fact that the deflection means comprise a longitudinal deflector substantially parallel to the tube bundle, intended to divide the housing into two circuits, said deflector being fixed by its longitudinal edges to the walls internal to the housing and its transverse edges to two support plates by welding.

55 De este modo, se consigue un posicionamiento y ensamblaje más sencillo del deflector en el interior de la carcasa, así como una mejor fijación del mismo gracias a su unión mediante soldadura. Preferentemente se utiliza soldadura en horno, evitando así la utilización de puntos de soldadura como ocurría con los deflectores conocidos en el estado de la técnica. 55 In this way, a simpler positioning and assembly of the deflector inside the housing is achieved, as well as a better fixation thereof thanks to its welding connection. Preferably, furnace welding is used, thus avoiding the use of welding points as was the case with the baffles known in the state of the art.

Asimismo, el intercambiador 1 incluye medios de desviación dispuestos en el interior de la carcasa 2 susceptibles de direccionar el al menos un fluido refrigerante dentro de la carcasa 2. En este caso, los medios de desviación comprenden un deflector longitudinal 6 sensiblemente paralelo al haz de tubos, destinado a dividir la carcasa 2 en dos circuitos. Also, the exchanger 1 includes deflection means arranged inside the housing 2 capable of directing the at least one refrigerant fluid inside the housing 2. In this case, the deflection means comprise a longitudinal deflector 6 substantially parallel to the beam of tubes, intended to divide housing 2 into two circuits.

El deflector ubicado dentro de la carcasa 2 del intercambiador 1 permite mejorar la distribución de un fluido refrigerante o incluso separar dos fluidos diferentes, tal como aceite y un liquido de refrigeración, sin comunicación entre ambos dentro de una carcasa 2 común. A continuación se muestran dos realizaciones del deflector. The baffle located inside the casing 2 of the exchanger 1 makes it possible to improve the distribution of a refrigerant fluid or even separate two different fluids, such as oil and a coolant, without communication between the two within a common casing 2. Below are two embodiments of the deflector.

Según una primera realización mostrada en la figura 2, el deflector 6 comprende una superficie cerrada y homogénea que permite una perfecta estanqueidad entre los circuitos de dos fluidos refrigerantes. La finalidad de dicho deflector 6 es separar dos fluidos refrigerantes diferentes dentro de la carcasa 2, debido a sus distintas composiciones, propiedades, etc. Este tipo de deflector 6 es utilizado en intercambiadores en lo que es necesario utilizar diferentes circuitos de fluido refrigerante dentro del intercambiador para producir el intercambio de calor con los gases de escape que fluyen dentro de los tubos. According to a first embodiment shown in Figure 2, the deflector 6 comprises a closed and homogeneous surface that allows a perfect seal between the circuits of two cooling fluids. The purpose of said deflector 6 is to separate two different cooling fluids inside the housing 2, due to its different compositions, properties, etc. This type of baffle 6 is used in exchangers in which it is necessary to use different refrigerant fluid circuits inside the exchanger to produce heat exchange with the exhaust gases flowing inside the tubes.

En la figura 1 se puede apreciar un intercambiador 1 que utiliza dicho deflector 6 para separar dos tipos de fluido refrigerante. En este caso, se requieren dos conductos de entrada diferentes 7,7a y dos conductos de salida diferentes 8,8a en un mismo intercambiador 1. De este modo, se obtiene una adecuada separación de ambos fluidos refrigerantes dentro de una misma carcasa 2. En la figura 1 se ha representado mediante flechas la entrada y salida de ambos fluidos refrigerantes dentro de la carcasa 2, así como la entrada y salida de los gases dentro de la carcasa 2 y su cambio de sentido dentro de un depósito de gas (no representado). In Figure 1 an exchanger 1 can be seen that uses said deflector 6 to separate two types of cooling fluid. In this case, two different inlet ducts 7,7a and two different outlet ducts 8,8a are required in the same exchanger 1. In this way, an adequate separation of both coolants inside the same housing 2 is obtained. Figure 1 is represented by arrows the inlet and outlet of both cooling fluids inside the housing 2, as well as the entry and exit of the gases inside the housing 2 and its change of direction within a gas tank (not shown). ).

Según una segunda realización mostrada en la figura 3, el deflector 6a comprende una abertura pasante 9 en su superficie para el paso de un fluido refrigerante desde una mitad a otra mitad de la carcasa 2, con el fin de optimizar la distribución del fluido refrigerante dentro de la carcasa 2. Por tanto, este tipo de deflector 6a es usado para incrementar los rendimientos o mejorar la distribución del fluido refrigerante dentro de la carcasa 2. According to a second embodiment shown in Figure 3, the deflector 6a comprises a through opening 9 on its surface for the passage of a refrigerant fluid from one half to another half of the housing 2, in order to optimize the distribution of the refrigerant fluid within of the housing 2. Therefore, this type of deflector 6a is used to increase the yields or improve the distribution of the refrigerant fluid within the housing 2.

En las figuras 4 y 5 se puede apreciar un intercambiador 1 que utiliza dicho deflector 6a, cuyos conductos de entrada 7 y salida 8 están situados en un mismo extremo de la carcasa 2. En la figura 4 se ha representado mediante flechas la entrada y salida del fluido refrigerante dentro de la carcasa 2. In Figures 4 and 5, an exchanger 1 can be seen using said deflector 6a, whose inlet and outlet ducts 8 are located at the same end of the housing 2. In Fig. 4, the inlet and outlet are represented by arrows of the cooling fluid inside the housing 2.

Debido a las restricciones de empaquetado o a los requisitos del fabricante de vehículos, puede ser necesario que los conductos de entrada 7 y salida 8 del fluido refrigerante estén situados a una corta distancia entre sí o incluso en el mismo extremo de la carcasa 2, lo cual puede ocasionar una trayectoria preferible para el fluido refrigerante con el consiguiente impacto en el llenado del fluido refrigerante y una mala refrigeración de los tubos de gases, así como la posibilidad de tener puntos de estancamiento que pueden provocar el fenómeno de ebullición con el consecuente daño del intercambiador. En este caso, el deflector 6a provisto de su abertura 9 permite mejorar la circulación del fluido refrigerante dentro del intercambiador. Due to packaging restrictions or the requirements of the vehicle manufacturer, it may be necessary that the inlet and outlet ducts 7 of the coolant are located a short distance from each other or even at the same end of the housing 2, which it can cause a preferable trajectory for the refrigerant fluid with the consequent impact on the filling of the refrigerant fluid and a bad cooling of the gas pipes, as well as the possibility of having stagnation points that can cause the boiling phenomenon with the consequent damage of the exchanger In this case, the deflector 6a provided with its opening 9 allows to improve the circulation of the refrigerant fluid inside the exchanger.

El deflector 6,6a de la presente invención incluye en su configuración unas aletas periféricas dobladas 10 en ambos bordes longitudinales, tal como puede observarse en la figura 6, destinadas a unir el deflector 6,6a a sendas paredes internas de la carcasa 2 mediante preferentemente soldadura en horno (ver figura 7). De este modo, se evita el uso de puntos de soldadura entre el deflector 6,6a y la carcasa 2 como ocurría con los deflectores conocidos en el estado de la técnica, The deflector 6,6a of the present invention includes in its configuration folded peripheral fins 10 on both longitudinal edges, as can be seen in Figure 6, intended to join the deflector 6,6a to both internal walls of the housing 2 by preferably oven welding (see figure 7). In this way, the use of welding points between the baffle 6,6a and the housing 2 is avoided as was the case with the baffles known in the state of the art,

Asimismo, el deflector 6,6a de la presente invención incluye en sus bordes transversales sendos tramos salientes 11, como puede apreciarse en las figuras 6, 8 y 9, susceptibles de encajar en respectivas ranuras 12 practicadas en las placas de soporte 5 (ver figuras 10 y 11), permitiendo que el deflector 6,6a quede fijado en la posición apropiada antes de ser soldado. En este caso, el ensamblaje del deflector 6,6a se realiza de un modo parecido al proceso de ensamblaje de los tubos con dichas placas de soporte 5. Likewise, the baffle 6,6a of the present invention includes in its transverse edges two protruding sections 11, as can be seen in Figures 6, 8 and 9, capable of fitting into respective grooves 12 made in the support plates 5 (see figures 10 and 11), allowing the deflector 6,6a to be fixed in the appropriate position before being welded. In this case, the assembly of the baffle 6,6a is carried out in a manner similar to the process of assembling the tubes with said support plates 5.

A modo de ejemplo, en las figuras 1, 12 y 13 se muestran respectivamente distintas configuraciones de intercambiadores 1 que utilizan dos fluidos refrigerantes, estando sus respectivos conductos de entrada 7,7a y salida 8,8a dispuestos según diferentes posiciones relativas en la carcasa 2. En este caso, se utiliza un deflector 6 cerrado (ver figura 2) para separar ambos fluidos refrigerantes. By way of example, different configurations of exchangers 1 using two refrigerant fluids are shown in Figures 1, 12 and 13, their respective inlet ducts 7,7a and outlet 8,8a being arranged according to different relative positions in the housing 2 In this case, a closed baffle 6 is used (see figure 2) to separate both cooling fluids.

Por otra parte, en las figuras 4 y 14 se muestran respectivamente distintas configuraciones de intercambiadores que utilizan un único fluido refrigerante cuyo par de conductos de entrada 7 y salida 8 está situado en mismo extremo de la carcasa 2, estando dichos conductos 7,8 dispuestos con diferentes posiciones relativas en la carcasa 2. En este caso, se utiliza un deflector 6a provisto de una abertura pasante 9 (ver figura 3) para mejorar la distribución del fluido refrigerante. On the other hand, different configurations of exchangers are shown in Figures 4 and 14 respectively, using a single refrigerant fluid whose pair of inlet and outlet ducts 7 is located at the same end of the housing 2, said ducts 7,8 being arranged with different relative positions in the housing 2. In this case, a deflector 6a provided with a through opening 9 (see Figure 3) is used to improve the distribution of the cooling fluid.

El deflector 6,6a de la invención puede ser utilizado en intercambiadores fabricados de acero inoxidable o aluminio. The deflector 6,6a of the invention can be used in exchangers made of stainless steel or aluminum.
