AI Technical Summary
Existing solar hot air-water heat exchange devices suffer from problems such as low heat exchange efficiency, limited contact area between hot air and water, difficulty in controlling fluid flow, limited space for hot air temperature increase, and contradiction between heat collection efficiency and heat exchange efficiency.
It adopts a closed hot air circulation loop and a heat exchange bellows structure with built-in spiral heat dissipation fins. Combined with a speed-regulating fan and pressure regulating valve, it creates a turbulent state by adjusting the flow rate and pressure, enhances heat exchange by using a phase change heat transfer medium, and improves solar energy absorption efficiency through a concentrating solar collector.
It significantly improves the air-water heat exchange efficiency, achieves efficient contact between hot air and water, expands the heat release temperature difference, synergistically improves heat exchange and heat collection efficiency, reduces energy consumption, and ensures the stability and reliability of the device.
