Colector solar complejo.Complex solar collector.
Campo de la invenciónField of the Invention
La presente invención se refiere a un colector solar complejo en sistemas energéticos de alta eficiencia, parques solares acuáticos, etc. El colector solar ha sido concebido y realizado para obtener numerosas y notables ventajas respecto a otros medios existentes de análogas finalidades.The present invention relates to a complex solar collector in high efficiency energy systems, solar water parks, etc. The solar collector has been conceived and realized to obtain numerous and notable advantages over other existing means of analogous purposes.
El colector solar está previsto para lograr producir energía a partir de la luz del sol de una forma eficiente. Para ello, el colector solar cuenta con 8 partes bien diferenciadas que encajan entre sí formando un único objeto que es capaz de convertir la luz recibida del sol en energía eléctrica.The solar collector is planned to produce energy from sunlight in an efficient way. For this, the solar collector has 8 distinct parts that fit together forming a single object that is capable of converting the light received from the sun into electrical energy.
Estado de la técnica anteriorPrior art
Se conocen varios sistemas y dispositivos para dotar de energía eléctrica a boyas, e incluso colectores solares en tierra firme cuya finalidad es recoger energía lumínica y concentrarla en un panel solar.Several systems and devices are known to provide electric power to buoys, and even solar collectors on the mainland whose purpose is to collect light energy and concentrate it on a solar panel.
En tal sentido pueden citarse boyas que consisten en un panel solar orientado hacia la trayectoria del sol y en el ángulo tangencial medio anual de maximizar la radiación incidente en el mismo proveniente del sol, el cual está unido a otras baterías de ciclo continuo sin mantenimiento, herméticamente selladas y sin intercambio gaseoso que son las que realmente alimentan las necesidades eléctricas de la boya.In this sense, buoys can be mentioned, which consist of a solar panel oriented towards the sun's path and the annual mean tangential angle of maximizing the incident radiation from the sun, which is connected to other continuous cycle batteries without maintenance, Hermetically sealed and without gas exchange are the ones that really feed the electrical needs of the buoy.
Este sistema presenta diversos inconvenientes, tales como el alto precio que tienen los paneles solares unido a la ineficiencia de los mismos más si cabe en un ambiente marino el cual agita la boya en todas las direcciones reduciendo la incidencia de los rayos solares. También hemos de tener en cuenta la existencia de un mercado negro de paneles solares dado su alto precio, y la casi imposible opción de proteger dichos paneles en una boya en el mar, tanto de forma física como de forma legal. Y desde luego, el alto peso que conlleva el panel y la estructura para mantenerlo en el ángulo correcto no ayudan en nada a la flotabilidad o la estabilidad de la boya.This system has several drawbacks, such as the high price that solar panels have, together with their inefficiency, even more so if it fits in a marine environment which waves the buoy in all directions, reducing the incidence of solar rays. We must also take into account the existence of a black market for solar panels given its high price, and the almost impossible option to protect these panels in a buoy at sea, both physically and legally. And of course, the high weight of the panel and the structure to keep it at the right angle do not help buoyancy or stability of the buoy.
Igualmente, se conocen otros sistemas basados en colectores solares en tierra los cuales concentran la energía solar en panel solar mediante una serie de espejos que reflejan su radiación incidente en el panel solar aumentando de esta forma la radiación incidente en panel solar y con ello la cantidad de energía total producida.Likewise, other systems based on solar collectors on the ground are known which concentrate solar energy on solar panels by means of a series of mirrors that reflect their incident radiation on the solar panel thereby increasing the incident radiation on the solar panel and with it the amount of total energy produced.
Sin embargo la potencia de estos colectores solares está limitada por la capacidad de refrigeración puesto que al aumentar la temperatura del panel a causa de que el 85% de la energía incidente se transforma en calor, disminuye la eficiencia del panel. La refrigeración tradicional por aire circundante no permite ir más allá de 2000 w/m2 de energía incidente. Aumentando la refrigeración mediante agua circulante o incluso la evaporación se pueden superar los 100000 w/m2. Sin embargo, la cantidad de agua necesaria hace prácticamente imposible su uso en zonas donde la radiación incidente tenga bastante potencia. Éstas son principalmente tierras secas donde escasea el agua y también está limitado el uso de ríos puesto que el aumento de la temperatura del agua tras pasar por el colector solar supondría incremento significativo de la temperatura media del río, lo cual supondría un gran impacto ecológico haciendo inviables las grandes instalaciones.However, the power of these solar collectors is limited by the cooling capacity since increasing the temperature of the panel because 85% of the incident energy is transformed into heat decreases the efficiency of the panel. Traditional cooling by surrounding air does not allow to go beyond 2000 w / m2 of incident energy. Increasing cooling by circulating water or even evaporation can exceed 100,000 w / m2. However, the amount of water needed makes it virtually impossible to use in areas where the incident radiation has enough power. These are mainly dry lands where water is scarce and the use of rivers is also limited since the increase in water temperature after passing through the solar collector would mean a significant increase in the average temperature of the river, which would have a great ecological impact by unfeasible large facilities.

Explicación de la invenciónExplanation of the invention.
El colector solar complejo de la invención presenta una nueva estrategia a la hora de explotar la energía del sol en el mar: aprovechando la eficiencia de diferentes modelos energéticos que presentan los paneles solares a una temperatura ambiente, unido a la potencia que conlleva la refrigeración por inversión acuática, su complementariedad con los módulos seebeck dada la constante térmica del agua, para mantenerlo a esa temperatura y los generadores stirling.The complex solar collector of the invention presents a new strategy when it comes to exploiting the sun's energy at sea: taking advantage of the efficiency of different energy models presented by solar panels at an ambient temperature, together with the power of cooling by aquatic inversion, its complementarity with the seebeck modules given the thermal constant of the water, to keep it at that temperature and the stirling generators.
El colector solar está diseñado para concentrar los rayos del sol mediante un espejo paraboide que focaliza toda la radiación en un espejo dicroico que a su vez focaliza la radiación electromagnética del visible levemente ampliado en el infrarrojo y muy ampliado en el ultravioleta en la base del espejo paraboide donde se encuentra un panel solar. Haciendo pasar las energías de dicho espectro a través del panel solar hasta un módulo seebeck y a continuación por un disipador al agua.The solar collector is designed to concentrate the sun's rays through a paraboid mirror that focuses all the radiation on a dichroic mirror that in turn focuses the electromagnetic radiation of the visible slightly enlarged in the infrared and greatly expanded in the ultraviolet at the base of the mirror paraboid where a solar panel is located. By passing the energies of said spectrum through the solar panel to a seebeck module and then through a heatsink to the water.
Dada la casi infinita cantidad de agua a temperatura constante disponible alrededor del colector solar y la alta constante térmica del agua podemos asegurar una temperatura inferior a los 300°K en el disipador, pudiendo diseñar el espejo colector para que el panel solar no supere los 550°K.Given the almost infinite amount of water at constant temperature available around the solar collector and the high thermal constant of the water we can ensure a temperature below 300 ° K in the heatsink, being able to design the collector mirror so that the solar panel does not exceed 550 ° K.
También existe la posibilidad de incrementar un fondo del espejo dicroico complementario que absorba el ultravioleta profundo y la mayor parte del infrarrojo, el cual se conectará con la cámara caliente de generadores stirling a través de un conducto metálico.There is also the possibility of increasing a background of the complementary dichroic mirror that absorbs the deep ultraviolet and most of the infrared, which will be connected to the hot chamber of stirling generators through a metallic conduit.
Además, se ha previsto que el espejo colector cuente con una tapadera transparente de forma que cierre herméticamente con el espejo colector pudiéndose hacer el vacío en su interior aislando térmicamente el espejo dicroico, manteniendo estables la presión de la cámara creada entre la tapadera y el espejo paraboide que además favorece la flotabilidad del colector solar.In addition, it is envisaged that the collector mirror has a transparent cover so that it closes tightly with the collector mirror and the vacuum can be made inside by thermally isolating the dichroic mirror, keeping the pressure of the chamber created between the lid and the mirror stable. paraboid that also favors the buoyancy of the solar collector.

Exposición detallada de modos de realizaciónDetailed statement of embodiments
Colector solar complejo para parques solares acuáticos que comprender un espejo colector paraboide (4) que se cierra mediante una tapadera transparente (5) y que concentra la radiación solar sobre un espejo dicroico (3) situado bajo la tapadera transparente (5), el cual se encuentra sustentado sobre el espejo colector paraboide (4) mediante unos conductos metálicos (8) los cuales además le sirven para exportar calor, debido al espectro no eficiente en la producción de electricidad, del interior del conjunto colector-tapadera transparente a unos generadores stirling (10)situados fuera de dicho conjunto; el espejo dicroico (3) enfoca el espectro más útil para la producción de electricidad sobre un panel solar (6), situado en la base del colector paraboide (4) y por la cara interior de éste, que lo convierte en electricidad o lo disipa en forma de calor en el agua pasado a través de un módulo seebeck que se encuentra en el exterior del colector paraboide (4) y acoplado al panel solar (6) por la cara opuesta a la que el panel solar (6) recibir la radiación solar proveniente del espejo dicroico (3).Complex solar collector for solar water parks that comprise a paraboid collector mirror (4) that is closed by a transparent cover (5) and that concentrates solar radiation on a dichroic mirror (3) located under the transparent cover (5), which It is supported on the paraboid collector mirror (4) by means of metallic conduits (8) which also serve to export heat, due to the non-efficient spectrum in the production of electricity, from the inside of the transparent collector-cover assembly to stirling generators (10) located outside said assembly; The dichroic mirror (3) focuses the most useful spectrum for the production of electricity on a solar panel (6), located at the base of the paraboid collector (4) and on the inside of the paraboid collector, which converts it into electricity or dissipates it in the form of heat in the water passed through a seebeck module that is located outside the paraboid manifold (4) and coupled to the solar panel (6) on the opposite side to which the solar panel (6) receive radiation solar from the dichroic mirror (3).
En la actualidad existen muy diferentes materiales con los que realizar las diversas partes del colector solar, y múltiples técnicas que podríamos utilizar en la confección de los espejos. No obstante, por simple economía elegiremos materiales y técnicas generalizadas, que resistan los medios acuáticos especialmente el marino. Así pues, para el disipador, y los conductos metálicos elegiremos aluminio mecanizado, al igual que para el espejo colector paraboide. Mientras que el espejo dicroico será de plata depuesto mediante sputtering en múltiples ciclos para hacerlo permeable al infrarrojo sobre un fondo de aluminio teñido con grafito y el panel solar será de los disponibles comercialmente monocristalino, la tapadera transparente será de vidrio embebido en metacrilato. los generadores stirling serán de los disponibles comercialmente para aplicaciones de hasta 2500°K. mientras que el módulo de seebeck serán para 550°K.At present there are very different materials with which to make the various parts of the solar collector, and multiple techniques that we could use in the manufacture of mirrors. However, for simple economy we will choose generalized materials and techniques that resist aquatic environments, especially the marine. So, for the heatsink, and the metallic ducts, we will choose machined aluminum, as for the paraboid collector mirror. While the dichroic mirror will be silver deposited by sputtering in multiple cycles to make it permeable to infrared on a graphite-stained aluminum background and the solar panel will be commercially available monocrystalline, the transparent cover will be made of methacrylate glass. Stirling generators will be commercially available for applications up to 2500 ° K. while the seebeck module will be for 550 ° K.
En consecuencia, para conseguir una potencial de 50 kw hora en un colector solar complejo en las aguas templadas partiremos de una lámina de aluminio de 0,09 m2 que deformáremos mediante un molde a presión de forma paraboide, recortando los bordes y perforando el centro, acto seguido lo puliremos. La tapadera la crearemos en un molde a partir de metacrilato monomérico y catalizador. La unión entre la tapadera y el espejo paraboide serán mediante epoxi. Realizaremos el vacío mediante una manguera elástica conectada a una bomba de vacío, introduciremos el panel solar aplastando la manguera, y retiraremos la manguera. Fijaremos el panel solar mediante epoxi, recubriremos la cara externa del panel solar con masilla termo conductora cerámica y colocaremos el módulo de seebeck, el cual también cubriremos con la misma masilla. Colocaremos en la cara opuesta el disipador y lo fijaremos al resto mediante epoxi. El disipador provendrá de disipadores de rectificadores de alta tensión. El espejo dicroico será una placa de aluminio cóncava por deformación mediante presión hidráulica pulida, que teñiremos de negro aplicándole una capa de grafito por sputtering de inducción magnética, y a continuación la volveremos a recubrir mediante una deposición de plata también por sputtering aunque en este caso simple. Dicha placa estará unida mecánicamente con losConsequently, to achieve a potential of 50 kw hour in a complex solar collector in the temperate waters, we will start from an aluminum sheet of 0.09 m2 that we will deform using a paraboid-shaped die mold, cutting the edges and drilling the center, We will immediately polish it. The cover will be created in a mold from monomeric methacrylate and catalyst. The connection between the cover and the paraboid mirror will be by epoxy. We will perform the vacuum using an elastic hose connected to a vacuum pump, introduce the solar panel by crushing the hose, and remove the hose. We will fix the solar panel by epoxy, we will cover the outer face of the solar panel with ceramic thermal conductive putty and place the seebeck module, which we will also cover with the same putty. We will place the heatsink on the opposite side and fix it to the rest using epoxy. The heatsink will come from high voltage rectifier heatsinks. The dichroic mirror will be a concave aluminum plate by deformation by means of polished hydraulic pressure, which we will dye black by applying a layer of graphite by magnetic induction sputtering, and then we will re-coat it by means of a silver deposition also by sputtering although in this case simple . Said plate will be mechanically connected with the
conductos metálicos y estos, a su vez, entrarán en la cámara caliente de los generadores Stirling, los cuales además de estar unidos mecánicamente a los conductos metálicos también estarán unidos al espejo paraboide mediante epoxi.metallic conduits and these, in turn, will enter the hot chamber of the Stirling generators, which in addition to being mechanically connected to the metallic conduits will also be attached to the paraboid mirror by epoxy.
5 Serán independientes del objeto de la invención los materiales empleados en la fabricación de los componentes del colector solar, formas y dimensiones de los mismos, y todos los detalles accesorios que puedan presentarse, siempre y cuando no afecten a su esencialidad.5 The materials used in the manufacture of the solar collector components, shapes and dimensions thereof, and all the accessory details that may arise, will be independent of the object of the invention, provided they do not affect their essentiality.
