AI Technical Summary
Existing solar energy medium-temperature heat utilization technologies suffer from high costs and low efficiency, especially with poor adaptability to different latitude regions. It is difficult to achieve stable and efficient heat collection performance under low-cost constraints, and efficiency loss is particularly severe within a 30° range of solar altitude angle variation.
The system employs a wide-adaptability microtrough solar thermal collector system, including a reflective concentrator assembly, modular linkage rods, heat exchangers, and support adjustment mechanisms. It utilizes an eccentric self-locking manual adjustment system and a heat-driven passive tracking system, combined with a spiral double-layer shell heat exchanger, to achieve efficient adaptation and stable heat collection for regions at different latitudes.
Without significantly increasing costs, it achieves stable and efficient heat collection within a 30° range of solar altitude angle variation, with a concentration ratio increased by more than 30%, a heat transfer coefficient increased by 35%, and a flow resistance reduced by 90%, adapting to the heat collection performance requirements of different regions around the world.
