DUAL-STAGE PARABOLIC CONCENTRATOR

摘要

An improvised Solar Concentrator and Absorber/Receiver Subsystem using a Dual-Stage Parabolic Concentrator for Concentrating Solar Power (CSP) (Thermal) system comprises of two parabolic mirrored reflectors wherein their apertures face each other with their focal point/line and axes coincides with each other, a plurality of absorber tubes/cavities placed on the non-reflecting side of the primary and/or secondary reflectors to carry heat transfer fluid, combined with relevant mechanisms to prevent/minimize thermal loss, mounted on a Sun tracking mechanism. For Concentrating Photovoltaic (CPV) and Concentrating Hybrid Thermo-Photovoltaic (CHTPV) Systems, all or a portion of the reflectors' reflecting and/or exterior surfaces would be covered or substituted with suitable photovoltaic panels.

1. A dual-stage parabolic concentrator based solar concentrator and absorber system, the system comprising:
a reflector subsystem with two parabolic mirrored reflectors—a larger primary reflector and a smaller secondary reflector, wherein apertures of the two reflectors face each other with their focal point and axes coinciding with each other to enable multiple reflection of sunlight hitting the primary reflector finally resulting in a thin, highly coherent and intense beam of light passing through the coinciding focal points along the coinciding axes of the two reflectors.
