Solar Evacuated tubes are the absorber of the solar water heater. They absorb solar energy converting it into heat for use in water heating.

Specifications

The selective coating on the inner tube collect solar energy and heat the heat pipe through the aluminium fins.

Heat Pipe Solar Tube

About heat pipe tube
1) Combines glass vacuum tube and copper heated pipe in one unit.
2) No water in copper heated pipe, which shortened the heating time.
3) Without water in glass vacuum tube, product can be used in cold weather of -30centi degree
4) Widely used for pressurized solar water heaters and solar projects

Working Pinciple:

The selective coating on the inner tube collect solar energy and heat

the heat pipe through the aluminium fins. The liquid in the heat pipe changes into vapour and then rise up to transfer the heat to the condenser.

Vapour becomes liquid after the heat been transferred. The process occurs again and again once the collector(s) is/are heated by the sun.
