U Tube Solar Collector

Through evacuated tubes solar energy is converted into heat energy, which is transferred to U pipe by an aluminum fin with high heat absorption and low heat loss. The anti-freeze liquid or water in the U pipe heats up, and the U pipe conducts thermal energy to the water inside the storage tank directly or through internal copper coil. The U tube solar collector comes with a testing pressure of 1.2 MPa, and a working pressure of 0.6MPa.

1) Manifold casing material: Aluminum alloy
2) Evacuated tube: Three-target tube with the coating AL-N/AL-CU
3) Heat pipe/U pipe: copper
4) Header pipe: copper
5) Insulating layer: Polyurethane foam
6) Frame: Aluminum alloy

Advantages
1) The U tube solar collector can be connected directly with city tap water.
2) With no water inside the evacuated tubes, the system can still work even several tubes are broken.
3) It can be used throughout the year in the cold climate.
