We are offering heat pipe vacuum tube. heat pipe vacuum tube: 1)perfect combination of vacuum tube and heat pipe 2)copper heat pipe, al fin 3)ce heat pipe vacuum tube: 1) higher heat efficiency: advanced heat transferring style of the heat pipe, excellent selective absorbent coating and perfect combination with vacuum heat preservation. 2) wide applicable range: as the heat pipe has less heat capacity, it can be started quickly even on cloudy days and collect heat effectively. It can work normally even at 30-degree. As there is 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. 4) the unique connection between the heat pipe and the vacuum tube can ensure both sealing and replacement glass vacuum tube.
