Product Description

Suntask Heat Pipe Solar Collector: SR

1. The pipeline is made of all the red copper and conducted by heat transfer medium liquid.

2. Water can't flow invacuum tubes and operated when confined.

3. The manifold uses aluminum alloy mould material of high strength with air flow design;

4. It is furnished in good style;

5. Can withstand high pressure when it works;

6. Module design, arbitrary combination, which can meet the demand of large water consumption.

Working Principle
The selective coating on the inner tube 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, returing to the bottom of the heat pipe. The heat conducts to the heat transfer liquid via a copper pipe. This transference of heat into the liquid creats a continuous circulation as long as the collector is heated by the sun.
