Separated Vacuum Tube Solar Collector

I) Brief Introduction:
All parameters of this kind of vacuum tube solar collector are consistent with the related standards of SICC of USA. To achieve the higest efficiency, the collector's absorber is sputtered with an aluminium nitride selective coating, which transforms majority incoming solar radiation into heat rapidly. The collector uses specially-designed TJ thimble that can effectively limit the temperature of condenser end and enhance the heating efficiency. Thanks to the outstanding rigid connection (tested by the pressure strength of 10kg/cm2) between TJ thimble and water tank, the solar collector has the advantages of durability and long lifetime. It is easy to be installed, and is especially applicable in large-scale engineering.
II) Features
Due to advanced heat transfer mode, excellent solar selective coating, and outstanding heat preservation based on high vacuum, the solar collector's daily average thermal efficiency can up to 50% or above even in winter in North China. The solar collector uses the rigid connection (tested by the pressure strength of 10kg/cm2) between TJ thimble and water tank, which guarantees high operating stability and avoids tube bursting, and ineffective sealing between glass tube and metal parts.
The solar collector uses modular design, thus can be convenient to be installed and maintained.
Thanks to high-performance heat transfer mode, it can be in good working order even at -30ÿ? Moreover, its tubes can resist the shocking of hail with the diameter of 35mm or below).
With advanced modular design and separated structure, the solar collector is more applicable in large-scale engineering projects.
