Description

Technical Field

[0001] The utility model relates to the technical field of solar energy, in particular to a solar energy heat collecting device. Background Art

[0002] A solar thermal collector is a device that uses solar energy to convert light energy into heat energy. The existing solar thermal collector installation structure is relatively complex. The device contains many accessories and components, and there are multiple connection points and vulnerable parts, which increases the difficulty and cost of maintenance and repair. In addition, the heat collection effect is poor, and further improvements are needed to improve the performance and reliability of the solar thermal collector. Since the collector is exposed to the external environment for a long time, its surface is susceptible to the adhesion of dust and other impurities. Over time, these dust and impurities will gradually accumulate, resulting in a decrease in the ability of the solar collector surface to transmit sunlight. This phenomenon in turn reduces the amount of heat that the absorber obtains from sunlight, thereby affecting the thermal efficiency of the solar collector. Existing solar thermal collectors usually adopt a single-sided collector design, which means that a single-panel collector cannot fully utilize solar energy. This single-sided design limits the flat-plate solar collector's ability to absorb solar energy, thereby affecting its energy conversion efficiency. Utility Model Content
