Himin solar energy group co.,ltd products

A U pipe collector is comprised of a manifold and many vacuum tubes each containing one U-shaped copper pipe. Sunlight is captured by the coated vacuum tubes which absorb the radiation as heat and conduct it through aluminum fins to the U pipes. A manifold on the top of the solar collector allows the working fluid (typically anti-freeze) to be pumped through all of the U pipes in parallel, and then through an external heat exchanger which transfers the heat to water in a pressurized storage tank.
