heat pipe vacuum tube for pressure solar collector

8)Patented conducting substance is compatible with normal metal material that results in non-condensable gas and non-stop running within 15 years and long duration for the collector.

7)No pipe crack, no incrustation

6)Daily heat efficiency up to 60% averagely.

backwards in cloud day or at night, no heat loss.

5)Degree of vacuum inside tubes up to 1.0*10-3Pa ensures heat preservation, One way heat conducting components ensure no heat conducting 

4)Low starting temperature (-60^oC), high speed conducting (6m/s), small thermal space,  less heat resistance.

3)High-speed conducting, less heat loss

2)High -efficiency heat emanation. Its condenser increases the heat exchange area with water.

1)easy structure and easy replacement
