Description
Panel de energía solar.Solar power panel.
La presente invención se refiere a un panel de energía solar.The present invention relates to a panel of solar energy.
Los paneles de energía solar son conocidos en la técnica. Como es sabido, permiten el calentamiento de líquidos, generalmente agua, aprovechando el calor de los rayos solares.Solar energy panels are known in the technique. As is known, they allow the heating of liquids, generally water, taking advantage of the heat of the sun's rays.
Los paneles de energía solar constan básicamente de un cristal que permite el paso de los rayos solares, bajo el cual se encuentra un conjunto de tubos, generalmente paralelos, por los que circula el líquido a calentar (habitualmente agua como se ha dicho).Solar energy panels basically consist of a crystal that allows the passage of solar rays, under the which is a set of tubes, generally parallel, by those that circulate the liquid to be heated (usually water as has said).
Sin embargo, los paneles de energía solar convencionales presentan dificultades para su uso en regiones donde las horas de sol son relativamente pocas. Se trata de un problema que sufren especialmente los paneles tradicionales planos de energía solar.However, solar energy panels Conventionals present difficulties for use in regions where Sunshine hours are relatively few. It is a problem suffering especially the traditional flat panels of solar energy.
Con el fin de superar este inconveniente se han propuesto paneles de energía solar como el que puede verse en la patente española núm. 506.525 en el que, cómo parte de un sistema de calentamiento de agua solar se describe un colector en forma de tejadillo de alzado triangular, dotado de tres caras formadas por un conjunto de tubos paralelos de material conductor sujetos a un bastidor y rodeado por otro bastidor que sustenta dobles láminas de vidrio. El acristalado permanece inclinado a 45°, lo que le dota de una mayor resistencia, permitiendo su fabricación con cristales con menos óxido de hierro que los habitualmente utilizados en esta técnica, de modo que permitan un mejor paso de la radiación solar.In order to overcome this inconvenience they have proposed solar panels like the one that can be seen in the Spanish patent no. 506.525 in which, as part of a system solar water heating describes a collector in the form of triangular elevation roof, equipped with three faces formed by a set of parallel tubes of conductive material attached to a frame and surrounded by another frame that supports double sheets of glass. The glazing remains inclined at 45 °, which gives it greater resistance, allowing its manufacture with crystals with less iron oxide than those commonly used in this technique, so that they allow a better radiation path solar.
Este tipo de panel permite conseguir el llamado "efecto invernadero", en virtud del cual los rayos solares no escapan del panel y permiten el aprovechamiento máximo del calor que generan. Se consigue así un calentamiento óptimo con un número de horas de sol comparativamente bajo.This type of panel allows to get the call "greenhouse effect", under which the sun's rays do not escape from the panel and allow maximum heat utilization that generate. Optimal heating is thus achieved with a number of comparatively low hours of sunshine.
Sin embargo, el panel de tres caras indicado es susceptible de un mejor funcionamiento, con un aprovechamiento superior del calor producido por los rayos solares.However, the three-sided panel indicated is susceptible to a better functioning, with a use superior heat produced by solar rays.
La invención consiste en un panel de energía solar que comprende tres caras de cristal formando un cuerpo prismático generalmente triangular, un conjunto de tubos colocados en el espacio delimitado por las tres caras señaladas, por cuyo interior circula el líquido a calentar, y al menos un reflector colocado bajo los tubos, en el que las caras están inclinadas formando un ángulo con respecto a la horizontal de entre aproximadamente 48° y aproximadamente 50°.The invention consists of an energy panel solar comprising three glass faces forming a body generally triangular prismatic, a set of placed tubes in the space delimited by the three faces indicated, by whose inside circulates the liquid to be heated, and at least one reflector placed under the tubes, in which the faces are inclined forming an angle with respect to the horizontal between approximately 48 ° and approximately 50 °.
En una realización, el reflector consiste en un espejo.In one embodiment, the reflector consists of a mirror.
En otra realización, las caras de cristal de dicho panel de energía solar son de karglass, con bajo contenido en hierro.In another embodiment, the glass faces of said solar energy panel are karglass, with low content in iron.
En otra realización, se coloca una capa de material aislante bajo el reflector; material aislante que puede ser fibra de vidrio o espuma de poliuretano expandido.In another embodiment, a layer of insulating material under the reflector; insulating material that can be fiberglass or expanded polyurethane foam.
En otra realización particular, las caras de cristal se sujetan mediante un bastidor que forma además la parte inferior del panel. Dicho bastidor puede estar formado por una chapa de acero inoxidable 304.In another particular embodiment, the faces of glass are held by a frame that also forms the part bottom of the panel. Said frame may be formed by a 304 stainless steel sheet.

Dichos tubos pueden estar soportados por al menos un bastidor de forma generalmente triangular, que puede ser un tubo doblado en su parte superior por el que también circula el líquido a calentar, combinado con un tubo transversal inferior. Ventajosamente, cada cara lateral presenta siete tubos de cobre de aproximadamente 12 mm. de diámetro, que pueden estar separados por una distancia de aproximadamente 40 mm. de eje a eje. Ventajosamente también, los tubos correspondientes a la parte inferior del panel son veintiséis tubos de cobre de aproximadamente 12 mm. de diámetro que pueden estar separados por una distancia de aproximadamente 20 mm. de eje a eje.Still in another particular embodiment, the tubes through which the liquid to be heated circulates are arranged in triangular alignment all along the panel. Such tubes they can be supported by at least one frame generally triangular, which can be a tube bent in its part superior through which the liquid to be heated also circulates, combined with a lower cross tube. Advantageously, each Side face features seven copper tubes of approximately 12 mm in diameter, which can be separated by a distance of approximately 40 mm from axis to axis. Advantageously too, the tubes corresponding to the bottom of the panel are twenty six copper tubes of approximately 12 mm. in diameter that can be separated by a distance of approximately 20 mm. shaft to axis.

Como puede verse en las figuras 1 y 2, en el espacio delimitado por dichas caras existe un conjunto de tubos 5, por cuyo interior circula el líquido a. calentar (en general, agua). Dichos tubos 5 están dispuestos longitudinalmente a lo largo del panel 1 de energía solar, y adoptan (como puede verse específicamente en la figura 3) una alineación triangular, distribuyéndose en tres planos (dos de ellos correspondientes, respectivamente, a las caras 2 y 3, y el tercero correspondiente a la parte inferior del panel 1). Los conjuntos de tubos correspondientes a las caras 2 y 3 se prolongan bajo la cara 4 doblándose hacia abajo y convergiendo en un tubo 10 hueco por el que también circula líquido a calentar. Los tubos 5 pueden ser tubos de cobre de aproximadamente 12 mm. de diámetro, que pueden ventajosamente distribuirse en un grupo de siete tubos por cada una de las caras 2 y 3, separados entre sí por distancias iguales de aproximadamente 40 mm. de eje a eje, y veintiséis tubos en el plano correspondiente a la parte inferior del panel 1, separados entre si por distancias iguales de aproximadamente 20 mm. de eje a eje de los tubos.As can be seen in figures 1 and 2, in the space delimited by said faces there is a set of tubes 5, through which the liquid circulates a. warm up (in general, Water). Said tubes 5 are arranged longitudinally along of solar panel 1, and adopt (as can be seen specifically in figure 3) a triangular alignment, distributed in three planes (two of them corresponding, respectively, to faces 2 and 3, and the third corresponding to the bottom of panel 1). Tube assemblies corresponding to faces 2 and 3 extend under face 4 bending down and converging in a hollow tube 10 through the that also circulates liquid to heat. The tubes 5 can be copper tubes of approximately 12 mm. in diameter, which can advantageously distributed in a group of seven tubes for each of faces 2 and 3, separated from each other by equal distances of approximately 40 mm from axis to axis, and twenty-six tubes in the plane corresponding to the bottom of panel 1, separated from each other for equal distances of approximately 20 mm. from axis to axis of the tubes
