TUBO DE MÚLTIPLES CONDUCTOS PARA INTERCAMBIADOR DE CALOR Sector de la técnica MULTIPLE CONDUCT TUBE FOR HEAT EXCHANGER Technical sector
La presente invención está relacionada con los sistemas de tratamiento de aire que establecen una circulación de aire saliente y una circulación de aire entrante, respecto de los recintos de aplicación, con aprovechamiento de la temperatura del aire saliente para adaptar térmicamente el aire entrante, proponiendo un tubo con unas particulares características estructurales, que determina en un conjunto estructural monopieza una multiplicidad de conductos por los que se puede establecer la circulación separada de dos flujos de aire en unas condiciones óptimas de intercambio de calor entre ellos, facilitando la instalación de los mencionados sistemas de tratamiento de aire, con unas condiciones de gran eficiencia de los mismos. The present invention is related to air treatment systems that establish a circulation of outgoing air and a circulation of incoming air, with respect to the application enclosures, taking advantage of the temperature of the outgoing air to thermally adapt the incoming air, proposing a tube with particular structural characteristics, which determines in a single-piece structural assembly a multiplicity of ducts through which the separate circulation of two air flows can be established under optimal conditions of heat exchange between them, facilitating the installation of said systems of air treatment, with conditions of great efficiency of the same.
Estado de la técnica State of the art
Para la renovación del aire del interior de recintos, es habitual la utilización de sistemas que permiten extraer el aire del interior de los recintos e introducir aire exterior, renovando así el aire del interior de los recintos que puede estar viciado por causas degradantes, como la acumulación de personas, humos, olores, etc. For the renewal of the air inside the enclosures, it is usual to use systems that allow to extract the air from the inside of the enclosures and introduce outside air, thus renewing the air inside the enclosures that may be vitiated by degrading causes, such as accumulation of people, fumes, odors, etc.
Por otro lado, para el mantenimiento de unas condiciones térmicas de confort en el interior de los recintos, se utilizan habitualmente medios calefactores, como aerotermos, estufas o instalaciones de calefacción, y medios de refrigeración, como instalaciones de aire acondicionado, o sistemas mixtos, como las bombas de calor, que permiten tanto el calentamiento como la refrigeración, en función de las necesidades. Todos esos sistemas y medios son eficaces para la función de la adaptación térmica ambiental, pero conllevan un elevado consumo energético para su funcionamiento, resultando el uso de los mismos de un alto costo, y además en general producen emanaciones perjudiciales para el medio ambiente. Debido a tales inconvenientes, se han desarrollado sistemas, como el de la Patente ES 2447642, de la misma titular que la presente invención, que permiten adaptación térmica del aire exterior que se introduce en los recintos, mediante aprovechamiento de las condiciones térmicas del propio aire que se extrae del interior de los recintos en el proceso de la renovación, determinando una relación que establece una aportación de esas condiciones térmicas al aire de renovación que se introduce desde el exterior, lo cual permite una reducción del consumo energético del proceso de la renovación. On the other hand, for the maintenance of thermal comfort conditions inside the enclosures, heating means are usually used, such as air heaters, stoves or heating installations, and cooling means, such as air conditioning installations, or mixed systems, such as heat pumps, which allow both heating and cooling, depending on the needs. All these systems and means are effective for the function of environmental thermal adaptation, but they entail a high energy consumption for their operation, resulting in their use of a high cost, and also in general produce emanations harmful to the environment. Due to such drawbacks, systems, such as that of ES Patent 2447642, of the same holder as the present invention have been developed, which allow thermal adaptation of the outside air that is introduced into the enclosures, by taking advantage of the thermal conditions of the air itself that is extracted from the interior of the enclosures in the renovation process, determining a relationship that establishes a contribution of these thermal conditions to the renewal air that is introduced from the outside, which allows a reduction of the energy consumption of the renovation process.
Dichos sistemas utilizan un recuperador de calor que posee un intercambiador térmico en el que se relacionan sin mezclarse dos circulaciones de aire que corresponden al aire saliente y al aire entrante en los recintos de aplicación. Los intercambiadores térmicos convencionales que se utilizan para esa función, constan de una pluralidad de tubos que se disponen entre unas placas extremas orificadas que hacen de soporte de los mismos, incorporándose ese conjunto dentro de una carcasa tubular, de manera que por el interior de los tubos dispuestos entre las placas extremas se hace pasar una circulación de aire y por el interior de la carcasa tubular otra circulación de aire que pasa por el exterior de los tubos, en contacto con ellos, pero sin mezclarse con el aire que circula por el interior de los mismos. Dicha estructuración resulta eficaz a los efectos del intercambio térmico entre los flujos de aire que pasan por el interior y por el exterior de los tubos del intercambiador, pero resulta de una construcción muy costosa, debido que cada tubo componente se tiene que unir individualmente a las placas extremas para formar el intercambiador de calor. These systems use a heat recuperator that has a heat exchanger in which two air circulations that correspond to the outgoing air and the incoming air in the application enclosures are related without mixing. The conventional heat exchangers that are used for this function, consist of a plurality of tubes that are arranged between orified end plates that support them, incorporating that assembly into a tubular housing, so that inside the tubes arranged between the end plates are passed through an air circulation and through the interior of the tubular casing another air circulation that passes through the outside of the tubes, in contact with them, but without mixing with the air circulating inside thereof. Such structuring is effective for the purposes of thermal exchange between the air flows that pass through the inside and outside of the exchanger tubes, but results from a very expensive construction, because each component tube has to be individually attached to the end plates to form the heat exchanger.
Objeto de la invención Object of the invention
De acuerdo con la invención se propone un tubo desarrollado con unas características estructurales que determinan una realización constructiva muy ventajosa, con una configuración que resulta perfectamente adecuada para establecer unas circulaciones de aire independientes con transferencia térmica entre ellas. According to the invention, a tube developed with structural characteristics that determine a very advantageous constructional embodiment is proposed, with a configuration that is perfectly suitable for establishing independent air circulations with thermal transfer between them.
Este tubo objeto de la invención consta de una estructura formada por una estructura monopieza que determina una pluralidad de conformaciones tubulares paralelas, las cuales van unidas a una placa lateral que cierra lateralmente a dichas conformaciones y hace de soporte de las mismas, quedando entre las mencionadas conformaciones tubulares unos espacios intermedios que constituyen zonas por las que puede circular longitudinalmente un flujo de aire en contacto con las mencionadas conformaciones tubulares. Se obtiene así un tubo que define longitudinalmente unas conformaciones tubulares, por las que puede circular un primer flujo de aire, y entre dichas conformaciones tubulares unos espacios por los que puede circular un segundo flujo de aire sin mezclarse con el primer flujo de aire pero en contacto con las conformaciones tubulares por las que circula dicha primer flujo de aire, de manera que a través de las paredes de las conformaciones tubulares se produce una transmisión térmica que permite la transferencia de calor entre ambos flujos de aire, desde el más caliente al más frío. This tube object of the invention consists of a structure formed by a single-piece structure that determines a plurality of parallel tubular conformations, which are attached to a side plate that closes laterally to said conformations and supports them, being among those mentioned tubular conformations intermediate spaces that constitute zones through which a flow of air can circulate longitudinally in contact with said tubular conformations. A tube is thus obtained that longitudinally defines tubular conformations, through which a first air flow can circulate, and between said tubular conformations spaces through which a second air flow can circulate without mixing with the first air flow but in contact with the tubular conformations through which said first air flow circulates, so that through the walls of the tubular conformations a thermal transmission that allows the transfer of heat between both air flows, from the hottest to the coldest.
La estructuración del tubo permite que las paredes de las conformaciones tubulares del mismo sean de muy poco grosor, lo cual favorece la transferencia del calor entre el primer flujo de aire que circula por el interior de dichas conformaciones tubulares y el segundo flujo de aire que circula por el exterior de las mismas, a lo largo del conjunto tubular. Además, las conformaciones tubulares, que se extienden según la dirección longitudinal del tubo y según cuerdas transversales de la sección del mismo, presentan una superficie de gran dimensión, lo cual favorece también la transmisión térmica entre el interior y el exterior de dichas conformaciones. The structuring of the tube allows the walls of the tubular conformations thereof to be very thin, which favors the transfer of heat between the first air flow that circulates inside said tubular conformations and the second air flow that circulates on the outside of them, along the tubular assembly. In addition, the tubular conformations, which extend according to the longitudinal direction of the tube and according to transverse cords of the section thereof, have a large surface area, which also favors thermal transmission between the interior and exterior of said conformations.
El tubo resulta además formado por un conjunto estructural monopieza de sección uniforme longitudinalmente, lo cual permite una fabricación del mismo en continuo por extrusión, para cortar la medida longitudinal que se necesite en cada caso, de manera que el conjunto monopieza del tubo simplifica mucho el montaje de la formación constructiva de los intercambiadores de calor de aplicación, ya que solo hay que manejar un único elemento tubular y no una multiplicidad de tubos independientes como en las soluciones estructurales de los intercambiadores de calor convencionales. The tube is also formed by a single-piece structural assembly of longitudinally uniform section, which allows continuous fabrication thereof by extrusion, to cut the longitudinal measure that is needed in each case, so that the single-piece tube assembly greatly simplifies the assembly of the constructive formation of the application heat exchangers, since only a single tubular element must be handled and not a multiplicity of independent tubes as in the structural solutions of conventional heat exchangers.
Dicho tubo objeto de la invención resulta por lo tanto de unas característica muy ventajosas para la formación de intercambiadores de calor a la que está destinado, adquiriendo vida propia y carácter preferente respecto de las soluciones convencionales de formación de los intercambiadores de calor con tubos independientes que hay que incorporarlos en el montaje individualmente. Descripción de las figuras Said tube object of the invention therefore results in very advantageous characteristics for the formation of heat exchangers to which it is intended, acquiring its own life and preferential character with respect to the conventional solutions of formation of heat exchangers with independent tubes which they must be incorporated into the assembly individually.

Descripción detallada de la invención Detailed description of the invention
El objeto de la invención se refiere a un tubo destinado para formar intercambiadores de calor, particularmente de los que se utilizan en recuperadores de calor de instalaciones de tratamiento de aire o similares, por los que se establecen unas circulaciones de aire que no se mezclan entre sí, pero que se influencian de manera que se produce un intercambio térmico entre ellas. The object of the invention relates to a tube intended to form heat exchangers, particularly those used in heat recuperators of air treatment facilities or the like, whereby air circulations are established that do not mix between Yes, but that they influence each other in a way that produces a thermal exchange between them.
El tubo según la invención consta de un conjunto estructural (1) monopieza formado por múltiples conformaciones tubulares (2) paralelamente dispuestas, las cuales van unidas lateralmente a una placa (3) que hace de soporte estableciendo una unión del conjunto de las mismas, estando dispuestas dichas conformaciones tubulares (2) paralelas entre sí, separadas por unos espacios (4) intermedios entre ellas. The tube according to the invention consists of a single piece structural assembly (1) formed by multiple parallel arranged tubular conformations (2), which are joined laterally to a plate (3) that acts as a support by establishing a joint assembly thereof, being said tubular conformations (2) parallel to each other, separated by intermediate spaces (4) between them.
La placa (3) envuelve parcialmente por un lado al conjunto estructural (1), en la medida de la distribución de las conformaciones tubulares (2), las cuales quedan cerradas por ese lado mediante dicha placa (3), mientras que por el otro lado se hallan cerradas por sí mismas. La formación de dicho conjunto estructural (1) del tubo es uniforme longitudinalmente, presentando una sección igual en toda la longitud, lo cual permite que pueda ser fabricado de manera continua por extrusión, para cortar trozos longitudinales de la medida que sea necesaria para cada aplicación. The plate (3) partially envelops the structural assembly (1) on the one hand, to the extent of the distribution of the tubular conformations (2), which are closed on that side by said plate (3), while on the other side are closed by themselves. The formation of said structural assembly (1) of the tube is uniformly longitudinally, presenting an equal section over the entire length, which allows it to be manufactured continuously by extrusion, to cut longitudinal pieces as necessary for each application. .
En esa formación del conjunto estructural (1) las conformaciones tubulares (2) pueden ser, por ejemplo, pero sin carácter limitativo, de una sección rectangular estrecha, quedando dispuestas según la dirección longitudinal del tubo, extendiéndose lateralmente en sentido transversal de la sección del mismo; y para que estructuralmente tengan una resistencia adecuada, dichas conformaciones tubulares (2) poseen interiormente entre sus paredes unos tabiques (5) de refuerzo que se extienden en la dirección longitudinal, los cuales establecen una división del interior de las mencionadas conformaciones tubulares (2) en secciones que forman conductos longitudinales, cuyo número puede variar en función de la dimensión de cada una de dichas conformaciones tubulares (2) en su extensión lateral en la anchura del conjunto estructural (1). In this formation of the structural assembly (1) the tubular conformations (2) can be, for example, but not limited to a narrow rectangular section, being arranged according to the longitudinal direction of the tube, extending laterally in a transverse direction of the section of the same; and so that structurally they have a suitable resistance, said tubular conformations (2) have internally between their walls reinforcing partitions (5) that extend in the longitudinal direction, which establish a division of the interior of said tubular conformations (2) in sections that form longitudinal ducts, the number of which may vary depending on the size of each of said tubular conformations (2) in its lateral extension in the width of the structural assembly (1).
La forma y la distribución de las conformaciones tubulares (2) puede variar, determinando distintas configuraciones de la sección transversal del conjunto estructural (1) del tubo, de acuerdo con la forma que se requiera en cada aplicación, por ejemplo en forma circular, como la realización de las figuras 1 y 2, en forma cuadrada, como la realización de las figuras 3 y 4, o en forma semicircular, como la realización de la figura 9, sin que estas configuraciones sean limitativas, ya que puede ser cualquier configuración redondeada, poligonal o mixtilínea. Resulta de esta manera un tubo que se puede disponer dentro de una carcasa tubular (6) correspondiente con el contorno del mismo, como se observa en las figuras 6 a 8, para hacer circular un flujo de aire por el interior de las conformaciones tubulares (2) y, por el interior de la carcasa tubular (6), pero por fuera de dichas conformaciones tubulares planas (2), otro flujo de aire que pasa por los espacios (4) que separan a las mencionadas conformaciones tubulares (2); de manera que la circulación de los dos flujos de aire se produce sin que se mezclen entre ellos, en unas condiciones de transferencia térmica eficaz desde el más caliente al más frío, a través de las paredes de las conformaciones tubulares (2). The shape and distribution of the tubular conformations (2) can vary, determining different configurations of the cross section of the structural assembly (1) of the tube, according to the shape that is required in each application, for example in a circular form, such as the embodiment of figures 1 and 2, in square form, such as the embodiment of figures 3 and 4, or in semicircular form, such as the embodiment of figure 9, without these configurations being limiting, since it may be any rounded configuration , polygonal or mixtilinear. This results in a tube that can be arranged inside a tubular housing (6) corresponding to the contour thereof, as seen in Figures 6 to 8, to circulate an air flow through the interior of the tubular conformations ( 2) and, inside the tubular housing (6), but outside said flat tubular conformations (2), another air flow passing through the spaces (4) that separate said tubular conformations (2); so that the circulation of the two air flows occurs without mixing between them, in conditions of effective thermal transfer from the hottest to the coldest, through the walls of the tubular conformations (2).
