3,first developed by our company
The introduction of solar heat pipe
1,All-glass double-vacuum solar heat pipe is made of high borosilicate glass 3.3 which are concentric,
the coating on the surface of the outer tube adopts advanced sputtering technology( SS-AlNx /Cu).
2,Compared to other common vacuum tubes,there is no water in the inner tube ,transferring thermal
energy by a special little fluid,consequently,it is not easy to break in winter even if the temperature
below minus 50°c.
3,Compared to other flat plate which uses costly metals like copper & aluminium,obviously, it is more
economical. All glass solar heat pipe is first developed by our company with independent intellectual
property rights,and the patent number is ZL99.221421.1.This product has been sold since 2005,which
