47*1500mm/47*1800mm/58*1800mm solar water heater vacuum tube and heat pipe

47*1500mm/47*1800mm/58*1800mm Solar Heat Pipe Vacuum Tube  

Heat pipe vacuum tubes features:

Heat pipe vacuum tube consists of the glass vacuum tube and a copper heat pipe which is fixed by aluminium flake and silicon plu.A perfect combination of the vacuum tube and the heat pipe.

• Anti-high temperature and Anti-freeze vacuum tube. The vacuum tube can withstand 400 high temperature and 30 Celsius degree below zero.
• High efficiency and Good performance. The vacuum tube can heat up rapidly, and even work very well on cloudy days.
• Constant warm keeping. The air between inner tube and outer tube is evacuated, which enable the tube to preserve heat.
•  Higher heat efficiency: advanced heat transferring style of the heat pipe, excellent selective absorb coating and perfect combination with high vacuum heat preservation.

•  Wide applicable range: as the heat pipe has less heat capacity, it can be started quickly even under cloudy fine day and collect heat effectively. It can work normally even-30 below degree. As no water in the vacuum tube, it can effectively prevent lowing of heat efficiency due to frost cracking or scaling.

• Each individual tube can work independently, and the whole machine can still work if individual tube is damaged. The service life of the heat pipe can be longer than 15years.

• The unique connection between the heat pipe and the vacuum tube can ensure both sealing and replace of damaged glass vacuum tube
