All-Glass Evacuated Solar Collector Tube with Heat Pipe
Feature:
Higher Absorbance, Lower emittance, dry exposure up to 270 degree
Higher efficiency, more heating
Absorbance coating layout:
Metal reflecting layer(copper)
Absorbance layer(SS aluminumnitride metal ceramic)
Remittance reducer layer(aluminumnitride)
Material borosillicate glass 3.3(T-0.91)
Coating SS-C/CU selective compound absorb coating
Absorbance 0.88-0.94
Remittance 0.08-0.04
VacuumDegree =<2x10-3Pa
Max. Pressure 6Bars
Hail resistance =<25mm
The vacuum tube adopt dry absorb type selective coating with lower remittance,
It solved the problem of normal tube having not good curve of remittance, when the temperature get higher, the remittance also become higher, which reduce the efficiency of the tube.
3 higher point of this new tube
Higher Efficency: The absorbance increased by 14% with remittance reduce by 30-40%
Higher Heat conduction: Dry exposure temperature up to 270 degree and can endure -30 degree environment temperature and still working
Higher Vacuum Degree: Unique technology to keep the vacuum degree, stable absorbance which guarantee the long life of the tube.
