Working
principle:
The selective coating on the inner cover of the evacuated tubes
converts solar energy into heat energy and transfers heat to the
heat pipes by aluminum fins, the liquid in the heat pipe changes
into vapour which rises to the condenser. The heat then passes
through the heat exchanger and the vapour becomes liquid, returning
to the base of the heat pipe. The heat conducts to the heat
transfer liquid(ante-freezing liquid or water) via a copper pipe.
This transference of heat into the liquid creates a continuous
circulation as long as the collector is heated by the
sun
