super conducting heat pipe vacuum tube
super conducting heat pipe vacuum tube

Minimum Order: 0
Quality/Safety Certification: 0.00

this is the core technology of the solar water heater.it shows the different efficience according to different quality

The heat conduction through the pipe is by the way of exchage of liquid and gas.The temperature difference is very low.Because of its high heat conduction feature and efficency,the pipe is used popularly in solar industry.

1.High heat conduction coefficient:is 2000-5000 times of matal materials.
2.High quantity of heat conduction:is 1000times od metal materials.
3.Low temperature difference:less than 4 difference in 2 meter long pipe.
