Description

Technical Field

[0001] This invention relates to the field of solar thermal collector technology, and particularly to solar thermal collector equipment. Background Technology

[0002] Solar energy is a green energy source in modern society. Utilizing solar energy can save significant amounts of energy, and achieving its full utilization is a necessity for modern societal development. In temperature control and insulation technologies, solar thermal collectors are widely used and have seen significant development due to their advantages such as utilizing solar energy, being pollution-free, easy to use, and having low long-term operating costs.

[0003] Currently, the most widely used solar thermal collection systems are evacuated tube collectors and flat plate collectors. However, evacuated tube collectors have a small light-gathering area and low light absorption efficiency, while flat plate collectors have poor heat preservation and large heat loss. Therefore, the temperature of evacuated tube collectors and flat plate collectors is only 40℃-60℃, which may be insufficient in some high-temperature applications such as industrial heating that requires temperatures greater than 80℃, resulting in the inability to fully utilize solar energy. Some solar integrated devices add concave and convex mirrors to increase illumination, but the position of the concave and convex mirrors cannot be adjusted according to changes in illumination, reducing the effectiveness of the concave and convex mirrors in increasing illumination. Therefore, this application provides a solar thermal collection device to meet the needs. Summary of the Invention

[0004] The purpose of this application is to provide a solar thermal collector device in which the curved reflector and the collector tube assembly can rotate with the change of the sun's angle.
