Solar Collectors

Pressurized Vacuum Tube U-Pipe Solar Collector

Working Principle:

Vacuum tubes absorb the solar radiation, and convert it into thermal energy, and then the thermo energy is transferred to U-pipes via the aluminum fin surrounding them. The heat transfer medium is heated when it flows through U-pipes. It continuously flows in via inlet and through U-pipes and gains more heat, and then flows into copper coils in split water tank to heat water.
