Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of solar energy collection, in particular to a vertical louver with a heat collection function and a working method thereof. BACKGROUND

[0002] There are various technologies related to solar energy utilization, which are widely used in building roofs, outer walls and other surfaces, such as solar water heaters, photovoltaic panels, concentrated photovoltaic systems, etc. These technologies effectively improve the self-sufficiency of building energy by converting solar radiation energy into heat or electricity. However, the utilization of solar energy for windows, a special light-receiving surface in buildings, is still relatively limited. As an important part of building lighting and ventilation, the primary function of windows is to ensure natural lighting and visual transparency indoors. Therefore, while utilizing solar energy, the light transmission and viewing function must be considered, which poses higher design requirements for the application of these technologies. Current mainstream technologies (such as patent CN 107246737 A) mostly use a double-layer structure design, i.e., a louver and a photovoltaic layer are separated, and the shading and partial power generation functions are achieved by adjusting the louver angle, while maintaining the light transmission and viewing properties of the window. However, such solutions still have low integration, poor aesthetics, and low power generation efficiency in practical applications, and there is a lack of specialized optimization design for the window light-receiving surface.

[0003] As a common building shading device, the louver is widely used to adjust indoor light intensity and prevent glare and overheating. However, traditional louvers are mostly horizontally arranged and have single functions, only serving as a shading device, which fails to effectively utilize the solar radiation energy incident on its surface, resulting in waste of light energy resources. Therefore, if solar energy conversion technology can be combined with the louver structure without affecting its shading and light adjustment functions, effective collection and conversion of light energy can be achieved, which not only improves the overall energy utilization efficiency of buildings, but also provides a new idea for solar energy application in window areas. This "functional shading" concept represents an important development direction for future integrated solar energy utilization technology in buildings. SUMMARY
