The structure and Character of All-glass Heat Pipe:
1. Inner glass tube
2. Solar selective coating: graded Al-N/Al, absorptance reach up to 93%, emittance
less than 6%.
3. Vacuum: with the pressure 5*10-2pa, sustained by the barium getter, the vacuum
degree will maintain 15 years.
4. Outer tube:Borosilcate glass 3.3 with good mechanism and good flexibility. In
the tube factory the raw glass tubes is controlled strictly and eliminate those with
bubbles.
5. metal Supporter
6. Keep vacuum material.
7. Evaporator
8. Shockproof ring:Protect the tubes during the transport.
9. Condensation part:Put into the tank,and transfer the heat into the water in the
tank.
10. Special working medium liquid:High efficiency heat transfer liquid,very low
frozen point.
Advantage of All-glass Heat Pipe:
1. Anti-freezing: Start quickly and anti-freeze even at -40℃.
2. Anti-cracking: Anti-crack even at 300℃.
3. Anti-leaking: Circulate without water, far away from leaking problem.
4. Anti-depositing: Transmit heat by Thsolar patent material.
