The features of solar thermal collector:

The heat pipe series solar collector are always connected with existing heating supply device.The selective coating on the inner cover or the evacuated tubes converts solar energy into heat energy and transfers heat to the heat pipes by Aluminum alloy.The liquid in the heat pipe changes into vapour which rises to the condenser.The heat conducts to the heat transfer liquid(anti-freezing liquid or water) via a copper pipe.This transference of heat in the liquid creates a continuous circulation as long as the collector is heated by the sun.

The Work Principle of solar thermal collector:

The operation of the solar collector is very simple. Solar absorption: solar radiation is absorbed by the solar tubes and converted into heat. Solar heat transfer: heat pipes conduct the heat from within the solar tube up to the header pipe 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 5-10°C. Throughout the day, the water in the tank is gradually heated.
