Title:
LIGHT-SPLITTING REFLECTION HIGH-POWER LIGHT-CONCENTRATING INTEGRATED PHOTOVOLTAIC AND PHOTO-THERMAL CAVITY RECEIVER
Document Type and Number:
WIPO Patent Application WO/2023/077833
Kind Code:
A1
Abstract:
A light-splitting reflection high-power light-concentrating integrated photovoltaic and photo-thermal cavity receiver in the present invention comprises a photo-thermal assembly and a photovoltaic module, wherein the photo-thermal assembly comprises a high-temperature heat storage system, a low-temperature heat storage system, and a reflection cavity formed by arranging a plurality of heat exchange tube bundles; an ultraviolet visible light reflection film is arranged on an inner surface of the reflection cavity, and the plurality of heat exchange tube bundles are in communication with each other to form a heat collection circuit; an input end of the heat collection circuit is connected to the low-temperature heat storage system, and an output end of the heat collection circuit is connected to the high-temperature heat storage system; the photovoltaic module is arranged at a light-concentrating focus of the reflection cavity, and comprises a near-infrared reflection film, a high-power light-concentrating photovoltaic integrated receiver, and a light-concentrating photovoltaic cooler, which are sequentially stacked in a light incident direction; and the reflection cavity is a parabolic revolution reflection cavity, and the parabolic revolution reflection cavity is formed by winding single-path annular heat exchange tube bundles or double-path annular heat exchange tube bundles. The present invention has a rational design, a simple structure and a high conversion efficiency, thereby effectively improving the heat collection grade.
