Heat Pipe Solar CollectorWork Principle:
1.Solar absorption: solar radiation is absorbed by the evacuated tube and converted into heat
2. Solar heat trasnfer: Heat pipes conduct the heat from vacuum tube inside to header tank of solar collector.
3. Solar energy storage: water or other liquid is circulated through the header tank, via intermittent pump cycling.
4. Circulation between solar collector and storage tank: each time the water or other liquid circulates through the header tank, the temperature is raised by 5-10°C, the water in the storage tank is heated gradually by this way.
