pressure copper U pipe U tube solar water thermal collector

U pipe solar collector
Working principle of CENTURY SUN U pipe solar collector.
The CENTURYSUN U pipe solar collector consists of 3 main components
1. ALL glass vacuum tube
2. Heat transfer system(solar cycle)
3. Frame
In each vacuum tube there is a U pipe with direct flow-through that is connected to the header pipe inside manifold. This U pipe is seamed in an aluminum heat transfer fin in the interior of vacuum tube that transmits the heat FROM the interior tube to the U pipe.
Solar radiation permeates the outer glass tube and is captured on the outside of inner glass tube by highly selective sputter layer. The captured solar radiation is transmitted to flush-contact aluminum shield and then copper pipe filled with heat transfer fluid. The 360°aluminum heat transfer fin assures the fastest energy transfer.

PERFORMANCE
CSU collector has been tested to EN12975 and achieved a comparable high efficiency and with a very small heat loss coefficient. The COST/KWH value is smaller than most other collectors which mean you pay less for each KWH out put for our collector.
