Haining baoguang solar vacuum tube

heat pipe solar vacuum tube

1.It has high Absorptivity and high collection efficiency
2.Get the big heat and Reduce heat loss
3.can be used on a variety of solar water heaters
4.Simple structure, easy for assembly and installation on different structure.

1.take out high temprature
2.Pressure to run fast and High structural strength
3.strong of Frost resistance
4.no water leakage in all life

The solar collector tubes have the special ability of absorbing solar energy, and they can form the high vacuum, which can reduce the heat loss to the greatest degree, because the selective coating can transfer the perpendicular incidence radiation and diffuse radiation to the super


It formed by copper rod and Aluminum and Three target solar vacuum tube

1.Can be used all year round even works well in extremely cold climate
.
2. Long lifespan, can be of good service more than 15 years
3.Simple structure, easy for assembly and installation on different structure

The solar collector tubes take on the available absorb solar energy and heat preservation adiabatic function, even if it located in disadvantage condition, it also can arrest drain of quality of heat. The collector takes on the transfer solar energy function rapidly. These optimize combination is superior to any other ones even if it is located in the uncommon conditions
