2, Features:
<1> Best heating efficiency: Heat pipe as heat exchanger, good absorbent coating and best combination between them!
<2> Wide applicable range: As the heat pipe has less heat capacity, it works very quick even under cloudy days and collect heat effectively. It can work normally even -30 degrees. As no water in the vacuum tube, it can effectively prevent low heat efficiency due to frost cracking or scaling!
<3> Each individual tube can work independently, and the whole system can still work if any one of them get damaged. The lifespan of our heat pipe is more than 15years.
<4> The connection between the heat pipe and vacuum tube is good and vacuum tube can be replaced if broken!
3, Working principle:
<1> On heat-pipe collector, the condenser of heat pipe is inserted to the copper manifold.
<2> After the solar energy is absorbed by the vacuum tubes, it is transferred to the heat pipe through the aluminum fin.
<3> The medium in the heat pipe will work and transfer the heat to the condenser.
<4> When water or other medium in the water pipe flows across the copper manifold, they will be heated.
<5> The heated water or other medium makes water in the tank hotter and hotter by running through the coils in the tank.
