Solarkeymark Certificate Tubular Heat Pipe Solar Thermal Water Collector

Product Description

Working principle:
The inside of the glass tubes are coated with a special black absorber that absorbs nearly all the energy of the sunlight falling on it. The aluminum wings transfer the heat energy to the heat pipe.
The liquid in the heat pipe boils and the steam travels up to the top of the heat pipe. The top bulb of the heat pipe (the condenser bulb) is in contact with Header Piper, which causes the vapour to condense.
The drops of condensed liquid then drip down the heat pipe. This cycle repeats so long as sunlight keeps heating the pipe and the top of the pipe is cool enough to condense the vapour.
Feature:
1) Use three target AL/N-SS/CU coating glass vacuum tube
2) Anti-freeze copper heat pipe, can working under cold climate
3) With Rock wool insulation
4)Anodized Aluminum 2.0mm thickness for both Manifold and frame
