How Heat Pipe Solar thermal Collector working?
1) The operation of the solar collector is very simple.
2) Solar absorption: solar radiation is absorbed by the solar tubes and converted into heat.
3) Solar heat transfer: heat pipes conduct the heat from within the solar tube up to the header pipe
4) 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 5-10C. Throughout the day, the water in the tank is gradually heated.
