Description

Heat Pipe Vacuum Tube Solar Collector Working principle Without water in the vacuum tube, the medium liquid such as glycol flows in the copper pipe in the vacuum tube to antifreeze in the winter. Every vacuum tube works as a single part. So one of them breakage will not affect the whole system. Specification: 1. Manifold: alloy aluminum 2.0mm thickness 2. Manifold connections(mm/inch): *8mm(outer)/*4mm(inner) 1’ 3. Bracket: alloy aluminum 1.8mm thickness 4. Vacuum tube: Al-N / AlN-SS / Cu ******0/******0 5. Heat pipe: diameter *2mm, thickness 1.0mm , anti-freezing liquid of glycol, can resist low temperature **5 degrees, 0.*5mm thickness 6. Insulation layer : polyurethane foam *5~*0mm 7. Distance from tube to tube: *5mm/*0mm 8. Installation Angle: *5~*5 degrees 9. Heat preservation: ****0 hours *0. Pressure: test pressure =*0 bar, safety work pressure=7bar *1. Hail resistance: *5mm Feature 1. The water is heated by the heat pipe rapidly; 2. There is no water in the vacuum tube, so the tube will not break in winter; 3. It can be combined with the architecture perfectly; 4. It can be combined with existing pipeline; 5. It will be affected by the local water quality, it doesn’t suit hard water; 6. It can still work in event of occasional tube breakage
