12tubes U pipe evacuated tube solar collector 

U pipe evacuated tube solar collector is a direct flow circulation solar collecting device. The U pipe is welded to main flow pipe as one piece. The aluminum fin is placed inside the tubes for heat conducting.Evacuated tubes covert the solar radiator energy into heat energy through the conduct aluminum fin to heat the glycol (usually for working the U Pipe evacuated tube solar collector is filled with glycol as heat transfer medium).Glycol as heat medium will be active or passive circulation to exchange heat with heat exchanger to heat the water to be hot for consumption.

U pipe evacuated tube solar collector designed as solar module can be easily connected in array for large hot water project.
