Vacuum Tube, Heat Pipe, Solar Collector
Characteristics:
1) The heat conduct through the pipe is by the way of exchange of liquid and gas.
2) The temperature difference is very low. Because of its high heat conduction feature and efficiency,
3) The pipe is used popularly in solar industry.
4) High heat conduction coefficient: It is 2000-5000 times of metal materials.
5) High quantity of heat conduction: It is 1000 times of metal materials.
6) Low temperature difference: less than 4℃ difference in 2 meter long pipe.
