Description
Intercambiador de calor para gases, en especial de los gases de escape de un motor.Heat exchanger for gases, especially of the 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, del tipo que comprende una pluralidad de conductos paralelos dispuestos en el interior de una carcasa, por los cuales circulan los gases a enfriar por intercambio térmico con un fluido de refrigeración, estando dichos conductos acoplados entre dos placas de soporte fijadas en ambos extremos de dicha carcasa, y presentando la carcasa y las placas de soporte una sección sensiblemente rectangular.The present invention relates to a heat exchanger for gases, especially gases from engine exhaust, of the type comprising a plurality of parallel ducts arranged inside a housing, by which circulate the gases to be cooled by thermal exchange with a cooling fluid, said ducts being coupled between two support plates fixed at both ends of said housing, and presenting the housing and support plates a substantially rectangular section.
La invención se aplica especialmente a intercambiadores de calor cuya carcasa, placas de soporte y conductos paralelos presentan una sección transversal sensiblemente rectangular. Preferentemente, se aplica a intercambiadores de pequeño tamaño tal como intercambiadores de recirculación de gases de escape de un motor (EGRC).The invention especially applies to heat exchangers whose housing, support plates and parallel ducts have a substantially cross section rectangular. Preferably, it is applied to heat exchangers Small size such as gas recirculation exchangers Exhaust 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, los dos medios que intercambian calor están separados por una pared.In some heat exchangers for the gas cooling, for example those used in recirculation of the exhaust gases towards the intake of an engine of explosion, the two means that exchange heat are separated by a wall
Más particularmente, los gases circulan por una serie de tubos o conductos paralelos dispuestos en el interior de una carcasa, y son enfriados por intercambio térmico con un fluido de refrigeración que se hace circular exteriormente a los conductos de paso de los gases.More particularly, gases circulate through a series of pipes or parallel ducts arranged inside a housing, and are cooled by heat exchange with a fluid of cooling that is circulated externally to the ducts of passage of gases.
Los tubos están fijados por sus extremos entre dos placas de soporte acopladas en cada extremo de la carcasa. Ambas placas de soporte presentan una pluralidad de orificios para la colocación de los respectivos tubos.The tubes are fixed at their ends between two support plates attached at each end of the housing. Both support plates have a plurality of holes for the placement of the respective tubes.
Los gases se alimentan al haz de tubos del intercambiador a partir de un conducto de entrada; puesto que el diámetro del conducto de entrada es inferior al diámetro de la carcasa y del haz de tubos del intercambiador, entre ambos hay un depósito de entrada que se ensancha progresivamente.The gases are fed to the tube bundle of the exchanger from an inlet conduit; since the diameter of the inlet duct is less than the diameter of the housing and the tube bundle of the exchanger, between them there is a entrance tank that widens progressively.
Son conocidos intercambiadores de calor cuya carcasa y placas de soporte presentan una sección transversal sensiblemente rectangular. En este caso, el montaje del intercambiador consiste primero en pre-ensamblar el conjunto formado por la carcasa, la pluralidad de tubos y las placas de soporte. A continuación, se procede a aplicar sobre dicho conjunto una pasta de soldadura, ensamblar los depósitos de gas, y soldar en horno el intercambiador de calor completo.Heat exchangers are known whose housing and support plates have a cross section substantially rectangular. In this case, the assembly of the exchanger first consists of pre-assembling the set formed by the housing, the plurality of tubes and plates of support. Then, we proceed to apply on that set a solder paste, assemble the gas tanks, and Bake the entire heat exchanger in the oven.
En la práctica se ha comprobado que las placas de soporte pre-ensambladas pueden sufrir desplazamientos no deseados durante el montaje del resto de componentes, ya que no existe ni soldadura ni ninguna unión mecánica entre las placas de soporte y la carcasa antes de llevarse a cabo la soldadura en horno de todo el intercambiador de calor.In practice it has been proven that the plates pre-assembled support may suffer unwanted displacements during assembly of the rest of components, since there is neither welding nor any mechanical union between the support plates and the housing before being carried out furnace welding of the entire heat exchanger.
Se conocen algunas soluciones para inmovilizar las placas de soporte durante el ensamblado del intercambiador de calor; por ejemplo, las placas de soporte pueden presentan un reborde destinado a abrazar el contorno de la carcasa, o bien, que las placas de soporte son abrazadas por la carcasa. También es posible utilizar soldadura en horno o soldadura láser para unir ambos componentes.Some solutions to immobilize are known the support plates during the assembly of the exchanger hot; for example, the support plates may have a flange intended to embrace the contour of the housing, or, that The support plates are hugged by the housing. It is also possible to use furnace welding or laser welding to join Both components
En el caso de intercambiadores de calor de carcasa y conductos de sección sensiblemente circular, una solución conocida es efectuar protuberancias con una herramienta a modo de punzón sobre la placa de soporte. Por una parte, las protuberancias ayudan al operario a identificar rápidamente la cara que debe ser situada contra la carcasa, ya que dicha cara es la que incluye las protuberancias. Por otra parte, dichas protuberancias también tienen la función de evitar el movimiento relativo de las placas de soporte respecto a la carcasa durante el montaje antes de la soldadura en horno. Este efecto se consigue gracias al contacto por rozamiento de las protuberancias con la zona periférica de la carcasa, por lo que éstas deben ser efectuadas en una zona próxima a la periferia de las placas de soporte.In the case of heat exchangers of housing and ducts of substantially circular section, a solution known is to make bumps with a tool as a punch on the support plate. On the one hand, the bumps help the operator to quickly identify the face that should be located against the housing, since said face is the one that includes the bumps Moreover, such bumps also they have the function of preventing the relative movement of the plates of support with respect to the housing during assembly before oven welding. This effect is achieved thanks to the contact by friction of the protuberances with the peripheral area of the housing, so these should be made in a nearby area to the periphery of the support plates.
Sin embargo, en la práctica se ha comprobado que resulta muy difícil mecanizar una carcasa de sección perfectamente circular, por lo que existe el riesgo de que algunas de las protuberancias queden fuera de la zona periférica de la carcasa, ocasionando así que las placas de soporte se muevan durante el montaje previo a la soldadura en horno.However, in practice it has been proven that It is very difficult to machine a section casing perfectly circular, so there is a risk that some of the protrusions are outside the peripheral area of the housing, thus causing the support plates to move during the assembly prior to oven welding.
El objetivo de la presente invención es resolver los inconvenientes mencionados, desarrollando un intercambiador de calor que permita inmovilizar las placas de soporte durante el montaje y soldadura del intercambiador.The objective of the present invention is to solve the mentioned disadvantages, developing an exchanger of heat that allows to immobilize the support plates during the assembly and welding of the exchanger.

De este modo, gracias al rozamiento producido entre las protuberancias y la superficie periférica de la carcasa, es posible evitar cualquier movimiento no deseado de las placas de soporte durante el ensamblaje y la aplicación de la soldadura en horno del intercambiador de calor.In this way, thanks to the friction produced between the protuberances and the peripheral surface of the housing, it is possible to avoid any unwanted movement of the plates support during assembly and welding application in heat exchanger oven.
