Specifications

solar heat pipe:
1,no water in the inner tube
2,transfer thermal by a special little liquid
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

is universally acknowledged and gain a promising market in China.
