Abstract

La présente invention concerne un dispositif capteur thermique d’énergie solaire. Du fait qu’il est pénétré modérément par la lumière du soleil, le dispositif remplit également la fonction d’éclairage. Le dispositif comprend un groupe de pièces de réflexion totale, une unité d’absorption d’infrarouge et un élément collecteur d’eau. La superposition de deux pièces transparentes, la fusion et le scellage de leurs bords forment la pièce de réflexion totale. Une couche d’air formée entre deux pièces transparentes peut entraîner une réflexion totale de la lumière du soleil dans l’eau. L’unité d’absorption d’infrarouge peut absorber la lumière du soleil, qui est réfléchie par les pièces de réflexion totale. L’élément collecteur d’eau est fait de matériau transparent, et est rempli d’eau. Le groupe de pièces de réflexion totale et l’unité d’absorption d’infrarouge sont prévus dans l’élément collecteur d’eau. L’utilisation de l’énergie solaire fait monter la température de l’eau dans l’élément collecteur d’eau.
