Description

Technical Field

[0001] The utility model relates to the technical field of collectors, and specifically relates to a solar collector panel. Background Art

[0002] The continuous growth of global energy consumption and the gradual depletion of fossil fuel resources have prompted governments and research institutions around the world to actively seek sustainable energy solutions. As one of the renewable energy sources, solar energy has become a research hotspot due to its clean, pollution-free and almost infinite characteristics. Among various solar energy utilization technologies, solar collectors are particularly crucial. They capture solar radiation and convert it into heat energy to provide energy support for building heating, hot water supply, industrial production processes, etc. However, although existing solar collectors have achieved certain results in applications, they generally have the following deficiencies:

[0003] The heat collection plates of traditional solar collectors usually adopt flat or simple curved surface designs, with limited heat absorption areas and being relatively sensitive to the incident angle of sunlight, resulting in low heat collection efficiency. In addition, the absorption rate and emissivity of existing heat collection plate materials for the solar spectrum are not ideal enough to fully utilize solar radiation energy.

[0004] In the design of traditional solar collectors, the insulation layer often only covers part of the area, and the thermal conductivity of the insulation material is relatively high, resulting in serious heat loss at night or on cloudy days. At the same time, the aging and shrinkage of the insulation layer will also reduce its insulation effect. The structural designs of many solar collectors are not compact enough, with large volumes and complex installations, increasing transportation and installation costs. In addition, some collectors lack flexible installation methods and are difficult to adapt to the characteristics of different buildings and sites. Solar collectors need to be regularly cleaned and maintained during use to ensure heat collection efficiency. However, the designs of some collectors are not conducive to these operations, such as the surface of the heat collection plate is not easy to clean and it is difficult to replace components.

By optimizing the structures and layouts of key components such as the heat collection plate, heat exchange box body, insulation layer, heat conduction sheet, heat exchange pipe, etc., the goals of efficient heat collection, good heat preservation, compact structure and easy maintenance are achieved.
