A perfect combination of the vacuum tube and the heat pipe.

 

1) higher heat efficiency: advanced heat transferring style of the

heat pipe, excellent selective absorb  coating and perfect

combination with high vacuum heat preservation.

 

2).Wide applicable range: as the en-source heat pipe has less heat 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.

 

3). 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 15 years.
