Flow type Heat pipe
The operation of the solar collector is very simple.
- Solar Absorption: Solar radiation is absorbed by the evacuated tubes and converted into heat.
- Solar Heat Transfer: Heat pipes conduct the heat from within the solar tube up to the header.
- Solar Energy Storage: Water is circulated through the header, via intermittent pump cycling. Each time the water circulates through the header the temperatures is raised by 5-10oC / 9-18oF. Throughout the day,
