Abstract

Captador lineal de energía solar y colector, formado por un tubo o conducto por cuyo interior circula un fluido caloportador que absorbe la radiación solar, siendo el captador lineal del tipo destinado a captar los rayos solares concentrados por un sistema de superficies reflectantes del tipo colector cilíndrico parabólico o del tipo Fresnel. En particular se refiere a un captador lineal del tipo que emplea aceite o sales fundidas como fluido caloportador destinadas a congelarse en el tubo o conducto captador en ausencia de radicación solar, y descongelarse cuando vuelve a existir dicha radiación. Asimismo, la invención se refiere a un colector solar, formado por el captador y un elemento parabólico, que en asociación con un dispositivo o mecanismo de movimiento del colector que, mediante un movimiento de abanico, reduce la irradiación que llega al tubo para limitar la potencia que le llega y, en consecuencia, mantener los gradientes térmicos de los materiales del captador dentro de límites aceptables.Linear solar energy collector and collector, formed by a tube or conduit through which a heat transfer fluid that absorbs solar radiation circulates, being the linear collector of the type intended to capture the solar rays concentrated by a system of reflective surfaces of the cylindrical collector type parabolic or Fresnel type. In particular, it refers to a linear collector of the type that uses oil or molten salts as heat transfer fluid intended to freeze in the collector tube or conduit in the absence of solar radiation, and thaw when such radiation reappears. Likewise, the invention relates to a solar collector, formed by the collector and a parabolic element, which in association with a device or mechanism of movement of the collector which, by means of a fan movement, reduces the irradiation that reaches the tube to limit the power that reaches it and, consequently, keep the thermal gradients of the collector materials within acceptable limits.
