Description

INTERCAMBIADOR DE CALOR DE PLACAS APILADAS HEAT EXCHANGER OF STACKED PLATES

La presente invención se refiere a un intercambiador de calor de placas apiladas. The present invention relates to a stacked plate heat exchanger.

5 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 especially applies to all types of heat exchangers within the scope of the engine, especially applies to exhaust recirculation exchangers of an engine (Exhaust Gas Recirculation Coolers or EGRC),

10 ANTECEDENTES DE LA INVENCIÓN 10 BACKGROUND OF THE INVENTION

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.

15 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 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 15 Basically, there are two types of EGR heat exchangers: a first type consists of a housing inside which a bundle of tubes is arranged for the passage of gases, the refrigerant circulating through the housing, externally to the tubes, and the second type consists of a series of parallel plates that constitute the heat exchange surfaces, so that the exhaust gases and the refrigerant circulate

2 O entre dos placas, en capas alternadas, pudiendo incluir aletas para mejorar el intercambio de calor. En el bucle del sistema de recirculación existe además una válvula EGR que controla el paso de gases de escape a través del intercambiador de calor. Son conocidos algunos intercambiadores de placas apiladas en los que 2 Or between two plates, in alternating layers, and may include fins to improve heat exchange. In the loop of the recirculation system there is also an EGR valve that controls the passage of exhaust gases through the heat exchanger. Some stacked plate exchangers are known in which

2 5 cada placa incluye una pared lateral longitudinal de cierre, estando cada par de placas montadas con sus respectivas paredes laterales dispuestas en los extremos longitudinales para la separación y cierre de los circuitos de los gases y de fluido refrigerante. Asimismo, cada circuito puede ser de tipo lineal, también denominado 2 5 each plate includes a longitudinal side closing wall, each pair of plates being mounted with their respective side walls arranged at the longitudinal ends for the separation and closing of the circuits of the gases and coolant fluid. Likewise, each circuit can be linear, also called

3 O en forma de quot;Iquot;, en el cual la entrada y salida de fluido están dispuestas en extremos opuestos; o bien puede ser en forma de quot;Uquot; en el cual la entrada y salida de fluido están dispuestas adyacentes en un mismo extremo abierto, estando el extremo opuesto cerrado, y definiendo un paso de ida y un paso de retomo a través de los canales de las placas. En este último caso, el extremo cerrado para el retomo de 3 Or in the form of "Iquot;" in which the fluid inlet and outlet are arranged at opposite ends; or it can be in the form of "Uquot; in which the fluid inlet and outlet are disposed adjacent at the same open end, the opposite end being closed, and defining a one-way passage and a return passage through the channels of the plates. In the latter case, the closed end for the return of

3 5 fluido suele estar constituido por un depósito cerrado. 3 5 fluid usually consists of a closed tank.

Existen dos posibles configuraciones en quot;Uquot; en los intercambiadores EGR de placas apiladas: There are two possible configurations in quot; Uquot; on stacked plate EGR exchangers:

a) to)
Configuración en quot;Uquot; vertical: el flujo de gases es dirigido a través de Configuration in "Uquot; vertical: the gas flow is directed through

la totalidad de los canales del circuito de gases de la mitad de las placas, all the channels of the gas circuit of half of the plates,

5 5
y es regresado por otros canales del circuito de gases pertenecientes al and is returned by other channels of the gas circuit belonging to the

resto de placas completamente diferentes. rest of completely different plates.

b) b)
Configuración en quot;Uquot; horizontal: el flujo de gases es dirigido a través Configuration in "Uquot; horizontal: the gas flow is directed through

de la mitad de los canales de la totalidad de placas, y es regresado por la of half of the channels of all the plates, and is returned by the

otra mitad de canales del circuito de gases pertenecientes a las mismas another half of the gas circuit channels belonging to them

10 10
placas. plates.

La mayor parte de los componentes de los intercambiadores EGR 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 Most of the components of the EGR exchangers 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

15 requerida para esta aplicación. 15 required for this application.

En algunos casos, el intercambiador EGR también puede incluir algunos componentes fabricados de plástico, los cuales pueden realizar una única o varias funciones fabricados en una única pieza. In some cases, the EGR exchanger may also include some components made of plastic, which can perform a single or several functions manufactured in a single piece.

La función principal de los intercambiadores EGR es el intercambio de The main function of the EGR exchangers is the exchange of

2 O calor entre los gases de escape y el fluido refrigerante, con el fin de enfriar los gases. Adicionalmente, los intercambiadores EGR tienen que satisfacer otras funciones secundarias como pueden ser el ensamblaje con el bloque motor, la conexión con el fluido refrigerante, o la conexión con el circuito de escape de gases. 2 Or heat between the exhaust gases and the cooling fluid, in order to cool the gases. Additionally, the EGR exchangers have to fulfill other secondary functions such as the assembly with the engine block, the connection with the coolant fluid, or the connection with the gas exhaust circuit.

En todos estos casos el proceso de fabricación requiere un elevado 2 5 número de juntas de soldadura en horno o soldadura por arco o láser, y en consecuencia resulta en una operación compleja y de elevado coste. In all these cases, the manufacturing process requires a large number of welding joints in the furnace or arc or laser welding, and consequently results in a complex and high-cost operation.

En intercambiadores de calor de placas apiladas, es necesario cerrar dos circuitos diferentes: fluido caliente y fluido frío. Usualmente, este tipo de intercambiadores de calor está fabricado mediante soldadura en horno. In stacked plate heat exchangers, it is necessary to close two different circuits: hot fluid and cold fluid. Usually, this type of heat exchanger is manufactured by oven welding.

3 O Para evitar caídas de presión elevadas, los fluidos entran directamente en el intercambiador de calor. No es posible utilizar tuberías, por lo que las soluciones típicas consisten en utilizar depósitos o accesorios para insertar el fluido dentro del intercambiador de calor. 3 O To avoid high pressure drops, fluids enter the heat exchanger directly. It is not possible to use pipes, so typical solutions consist of using tanks or accessories to insert the fluid into the heat exchanger.


El ensamblaje y soldadura en horno de este tipo de interfaces con las 3 5 placas apiladas puede generar problemas de calidad, es decir, fugas, por lo que es necesano que ambos circuitos de fluido refrigerante y gases estén adecuadamente cerrados para evitar posibles fugas.
The assembly and welding in this type of interfaces with the 3 5 stacked plates can cause quality problems, that is, leaks, so it is necessary that both refrigerant and gas circuits are properly closed to avoid possible leaks.

Para el concepto global de eficiencia, es muy importante, en configuraciones en quot;Uquot;, que el flujo de gas caliente no se mezcle con el flujo de gas 5 frío. Por supuesto, el flujo de entrada de gas nunca debe ir directamente a través del For the overall concept of efficiency, it is very important, in configurations in "," that the hot gas flow does not mix with the cold gas flow. Of course, the gas inlet flow should never go directly through the

flujo de salida de gas. gas outflow.

Debido a que el mercado tiende a reducir el tamaño de los motores, y a la aplicación de los intercambiadores de calor EGR no solo en aplicaciones de alta presión (HP) sino también en los de baja presión (LP), el espacio disponible para el Because the market tends to reduce the size of the engines, and the application of EGR heat exchangers not only in high pressure (HP) applications but also in low pressure (LP) applications, the space available for the

1 O intercambiador y sus componentes es cada vez menor. Los entornos donde el intercambiador EGR debe ser integrado son cada vez más complicados. De este modo, es importante desarrollar intercambiadores EGR compactos provistos de partes integradas que puedan ser colocados en el espacio disponible. 1 O exchanger and its components is getting smaller. The environments where the EGR exchanger must be integrated are increasingly complicated. Thus, it is important to develop compact EGR exchangers provided with integrated parts that can be placed in the available space.
