U-Pipe Solar Collector

Working Principle
The U-pipe solar collector mainly consists of a U-shaped water pipe, insulation layer, highly-absorptive vacuum tube, and frame. The U-shape 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 so that the water temperature of this standpipe becomes much higher than that of 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, which enables the U-pipe solar collector to work properly all year round in regions with severe winters.

Features
1. The solar collectors can be jointed in serial or parallel.
2. The working pressure can be up to 0.6 MPa.
3. The vacuum tube can be placed vertically or horizontally.
4. The system is easy to install and easy to maintain.
5. If an additional controller is installed, the whole water heating system can operate automatically.
6. U-pipe solar collector offers good water circulation, a high heat-exchanging rate, and it eliminates the risk of tube breaking or leaking.
