The heat pipe solar collector consists of heat pipe glass vacuum tube, pressurized manifold, supporting bracket and other related accessories
1) Solar heat pipe and its inner medium for thermal conduction, with a quick start and super daily efficiency about 55% in summer and 42% in winter, much more than that of the all-glass tube
2) The flow passage is inner closed and pressurized, no water or medium goes through glass vacuum tubes, no freeze to break vacuum tubes, able to serve in extremely cold weather
3) Heat pipe tip is inserted into a closed cannula welded into the copper flow passage, collector works well even withdrawal one or several heat pipe vacuum tubes
4) Aluminum alloy as bracket with super performance in chemical resistance, universal bracket suitable for slope and flat roof installation
5) Modularized collector, arbitrary combination with any architectural structure, adaptable to either slope roof or flat ground or upright walls, almost maintenance free collector
Warranty: 5 years international responsibility for solar collector and 15 years for glass tubes due to original quality problems
Applications:
Domestic hot water for shower, washing. Solar Thermal, Project: such as School, Hospital, Hotel.
