Abstract

Colector de canalón en forma parabólica para una central de energía solar. El colector de canalón de sección parabólica presenta un tubo absorbedor (14) por el cual circula un líquido portador del calor y dicho tubo absorbedor (14) está situado a lo largo de la línea focal de un colector de canalón de sección parabólica. El tubo absorbedor (14) está dispuesto excéntricamente en un tubo envolvente de vidrio (15). En el lado del tubo absorbedor (14) opuesto al reflector se halla dispuesto un reflector secundario (16) en forma de una placa plana. Este reflector secundario (16) reconduce al lado opuesto del tubo absorbedor aquella radiación reflejada por el reflector, que no incide en el tubo absorbedor (14). Ello permite que el tubo absorbedor (14) se pueda construir de menor diámetro de lo que sería usual. De esta manera se reducen las pérdidas por radiación y se aumenta el rendimiento del colector solar.
