Problems solved by technology

However, due to the unreasonable structural design of the drive structure adopted by the existing solar collectors, it is difficult to precisely control all the reflectors on the solar collectors to rotate at the same angle synchronously, especially for longer columns. This affects the absorption of solar heat
[0003] At the same time, most of the vacuum tubes used in existing trough solar collectors are metal straight-through tube structures. Not only the production process is complicated, the production efficiency is low, and the cost is very high, but also due to the limitations of the internal structure, the heat absorption rate is low, and the heat transport slow, ultimately affecting the absorption of solar heat
[0004] Moreover, with the single-axis tracking method, the optical cosine loss in the other direction is relatively large, resulting in low efficiency

technical field [0001] The invention relates to a solar heat collector, in particular to a high-efficiency heat pipe heat transfer dual-axis tracking and concentrating solar heat collector. Background technique [0002] At present, on the solar heat collector, in order to adapt to the change of the direction of sunlight, it is necessary to use a corresponding driving structure to drive the mirror to rotate to the most suitable angle. However, due to the unreasonable structural design of the drive structure adopted by the existing solar collectors, it is difficult to precisely control all the reflectors on the solar collectors to rotate at the same angle synchronously, especially for longer columns. This affects the absorption of solar heat. [0003] At the same time, most of the vacuum tubes used in existing trough solar collectors are metal straight-through tube structures. Not only the production process is complicated, the production efficiency is low, and the cost is ve...
