Detailed Product Description

Solar collector, vacuum tube with heat pipes, still work under -30 degree cold climate and without sunshine days

1, 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 aluminium fins. The liquid in the heat pipe changes into vapour which rises to the condendsor. The heat then passes through the heat exchanger and the vapour becomes liquid, returning to the base of the heat pipe. This transference of heat into the liquid creats a continuous circulation as long as the collector is heated by the sun.
