Structures design of reflector and absorber of solar energy concentrators

摘要

PURPOSE: A structure for forming a reflector mirror and a heat absorber plane of a light concentrator is provided, which maintains a constant concentration ratio of the concentrator and prevents an actual light loss by attaching a specific optical device or a heat absorbing device. CONSTITUTION: According to a light concentrator comprising two reflector planes formed with two parabolic curved planes and a cylindrical heat absorption tube and a cylindrical glass tube to accommodate the cylindrical heat absorption tube, a bottom of a glass tube(3) is revealed between two reflection planes(1) by forming the glass tube accommodating a heat absorption tube(2) between two reflection planes. And an assistant reflector mirror(10) comprising an extended curved surface of the parabolic curved planes of two reflector planes is formed between bottom surfaces of the heat absorption tube on an inner plane of the bottom of the glass tube.
