REFLECTOR-CONCENTRATOR UNIT, METHOD OF MANUFACTURING THE SAME, AND SOLAR COLLECTOR DEVICE COMPRISING SAID REFLECTOR-CONCENTRATOR UNIT

摘要

A reflector-concentrator unit including a sandwich structure with an upper lamina, a lower lamina, a filler layer between both, and a frame. The upper lamina has associated therewith an outer reflective surface to reflect incident rays and to concentrate them in a linear focus. The material of the filler layer is adhered to the upper and lower laminas of the sandwich structure and to the frame and is rigid enough to precisely assure a predetermined stable operating position of the upper lamina in relation to the frame. The frame includes positioning configurations usable to precisely position the reflector-concentrator unit and the associated reflective surface in relation to an external element of an installation.
