Components
1. Heat Pipe
Transfers the thermal energy from within the vacuum tube to the condenser efficiently and
rapidly
；
2. Glass tube top holder
The Part to hold the glass tubes to the manifold box
；
3. Cover
Stabilises the heat pipe and minimises the thermal energy loss from the glass tube
；
4. Conductive Aluminium fins
Transfer the thermal energy from the glass inner wall to the heat pipe more efficiently;
5. Vacuum layer between the glass skins;
6. Solar glass tube
High efficiency solar glass tube with maximum radiation absorption, minimum thermal
radiation losses and high insulation performance
；
7. Base / tube seal
This section has a mirror finish to minimise heat loss in the vacuum layer seal zone.
