U-Pipe Solar Collector

The U-pipe solar collector is characterized by good water circulation, high heat transfer efficiency, as well as no risk of tube breaking and leaking. It mainly consists of U-shaped water pipe, highly-absorptive vacuum tube, insulation layer, and frame.

The U-shaped copper pipe is inserted into the vacuum tube with the upper end going beyond the end of the vacuum tube. The aluminum fin for transferring heat is fixed on one standpipe of the U-shaped copper pipe so that the water temperature of this standpipe becomes much higher than that on the other side. The temperature difference results in a strong pushing force of water current.

As there is no water in the vacuum tube, if one tube is damaged, the solar collector can still work properly. As for the medium liquid for heat transferring, anti-freezing liquid is a good choice. It enables the U-pipe evacuated tube solar collector to work properly all year round in cold regions.

1. The U-pipe solar collectors can be connected in series or parallel.
2. The working pressure can be up to 0.6 MPa.
3. The vacuum tube can be placed vertically or horizontally, making it easy to install and maintain the solar thermal collector.
4. If an additional controller is installed, the whole solar water heating system can operate automatically.
