Solar heat light condenser

Abstract

Abstract PURPOSE:To enhance the heat collection effect of a solar heat light condenser employing a liquid lens, by providing a black heat collection tube which contains a heat collecting medium and is surrounded by a semicylindrical heat insulator and located on the focus of the liquid lens. CONSTITUTION:A hollow body, which is shaped like a semicylinder or a Fresnel semicylinder, is made of glass sheets, polymethyl methacrylate or the like. The hollow body is filled with water, glycerine or the like to manufacture a liquid lens 1 whose focus is located opposite a light incidence side. A black heat collection tube 4, through which water, glycerine or the like is caused to flow as a heat collecting medium, is provided on the longitudinal linear focus of the liquid lens 1. Since the liquid lens is used, weight reduction and simplification are enabled and a heat collection effect is heightened.
