Solar vacuum tube--All-glass double vacuum solar Heat Pipe

 

All-glass solar heat pipe is entirely made of borosilicate glass 3.3. In an all-glass solar heat pipe, the inner tube with transfer fluid sealed in is evacuated to form another vacuum beside the one between the outer and the inner tubes. This evacuated inner tube works almost like a  copper heat pipe.

 

When the selective coating absorbs solar energy, the transfer fluid will be heated up and evaporates at a low temperature. The vapour rises up to the condenser where it releases its heat energy to the water and then condenses. The transfer fluid flows back and is heated up again.

In this circulation, heat energy is transfered to water ready to be used.
