U Pipe Solar Collector
Each vacuum tube has a direct flow U pipe that is connected to the header pipe inside manifold. Each U pipe is seamed in an aluminum heat transfer fin inside of vacuum tube that transmits the heat from the inner tube to the U pipe. The liquid (usually a glycol-water antifreeze mixture) inside of the copper U pipe is heated, then conducts the heat energy to the water inside of storage tank through plate exchanger or internal spiral coil.

Product Introduction
Each vacuum tube has a direct flow U pipe that is connected to the header pipe inside manifold. Each U pipe is seamed in an aluminum heat transfer fin inside of vacuum tube that transmits the heat from the inner tube to the U pipe. The liquid (usually a glycol-water antifreeze mixture) inside of the copper U pipe is heated, then conducts the heat energy to the water inside of storage tank through plate exchanger or internal spiral coil.
In evacuated tubes, there is copper pipe folded into a U-shape with aluminum thermal conductors to transfer the solar energy from the inside wall of the evacuated tubes to the circulation fluid in it. Then the circulation fluuid take the heat energy into collectors manifold.
U pipe solar collector is the improvement of all-glass vacuum tube collector. If a vacuum tube is damaged, it would not affect the operation of systerm and can improve the reliability of system operation, because there is no water inpipe. Especially, u pipe solan collector can also be used to the closed system of pressure.
Main features
1)Higher efficiency η0 = 0.79 (aperture area).
2)Low temperature resistance, even can be work under -50°C ambient, so can be used all year round in cold climate area.
3)Passive tracks the sun: the round absorber surface of vacuumtubes passively track the sun throughout the day.
4)Available in 8,10, 12, 15, 18 and 20 tubes model, flexible combination.
5)No water inside vacuum tube, so vacuum tube will not breeak in the winter frozen weather.
6）In the event of a tube damaged, the whole system will still keep working, just remove and replace, low cost.
7) Combined with building perfectly, installation angle from 0° to 90°, ideal for slope roof or flat roof installation.
8) Solar Keymark(EN12975) certified.
