U-Pipe solar collector is a type of solar energy collector, which is appropriate in the central hot water supply system. "U" pipe vaccum tube collectors embed U-shaped metal pipe into vaccum tube the all glass tube. Vacuum tubes absorb solar energy, and through the flowing medium in the "U" pipe to reach the principle of heating water. "U" pipe solar collector is the same with heat pipe collector.They not only realized the glass tube doesn’t directly contact with the heated fluid, but retained the all-glass vacuum tube less cooling in the low temperature environment, and high temperature heating medium the advantages.Because the fluid is heated in the glass tube, whoes heat transfer more directly.Except the characteristics of high operating temperature,strong pressure ability, and best heat resistance, there are also such more advantages,it can be installed level, simplifyied mounting bracket, reduced the installation space area, avoided collector affect the appearance of the building, building integrated solar energy and has a more strong adaptability,and a more stronger adaptability between the solar and building construction.
Features:
1)vacuum tube take advantage of magnetron sputtering technology, high absorption rate 95% ± 2, low-emissivity 4% ± 2, the daily average of thermal efficiency of collector is ηd ≥75%.
2)The pipe running water is make up with copper, with ultrasonic cleaning and ultrasonic welding.
3)vacuum tube without water, even in-35 ℃ temperature conditions they still can run normally, overcoming the current vacuum tube blasting, freeze, sealing and the operation stability ect .
4)The system used steel materials for connections, non-silicone ring’s aging, leaking phenomenon, and can work in strong pressure.
