China PolCPC Solar Collector with Largest Aperature Area

Suntask Heat Pipe Solar Collector with CPC reflectors
Model No: SHC-8/9/10/12/14/15/1618/20/21/22/24
This solar collector have the largest aperture area and more output, especially suitable use for Poland new subsidy policy.

Vacuum solar collector working principle:

1. The heat pipe series vacuum solar collector are always connected with existing heating supply device.

2. 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.

3. The liquid in the heat pipe changes into vapour which rises to the condenser.

4. The heat then passes through the heat exchanger and the vapour becomes liquid, returning to the base of the heat pipe.

5. The heat conducts to the heat transfer liquid (anti-freezing liquid or water) via a copper pipe.

6. This transference of heat into the liquid creates a continuous circulation as long as the collector is heated by the sun.
