Features:
1. Internationally certified product
2. Reliable, efficient, twin-glass evacuated tubes with copper heat pipes for rapid heat transfer, no water enter into the tube, can be used in cold area.
3. Easy plug-in installation and maintenance.
4. Suitable for mains pressure water (up to 8 bar/116psi)
5. Corrosion resistant silver brazed copper header
6. Stable solar conversion throughout the day (tubes passively track the sun)
7. Perfect solar collector for domestic solar water heater systems.
8. Ideal for fro big project like swimming pool, school, hotel….
The operation of the solar collector is very simple.
1. Solar Absorption: Solar radiation is absorbed by the evacuated tubes and converted into heat.
2. Solar Heat Transfer: Heat pipes conduct the heat from within the solar tube up to the header.
3. Solar Energy Storage: Water is circulated through the header, via intermittent pump cycling. Each time the water circulates through the header the temperatures is raised by 5-10oC / 9-18oF. Throughout the day, the water in the storage tank is gradually heated.

Heat pipe vacuum tube:

Working Principle: Please refer to above picture. Sun’s ray will be collected by absorbers, then radiation can be transformed into heat energy by selective absorbing film. Heat energy have few material in heat pipe boiled away and gone up rapidly to condensation end and then become fluid. With the gravity, it goes back to evaporation end. Water can be heated through its continuous circulation. In order to make the fluid o back to evaporation end , the tilt angle should make more than 10 degree. |
