3 - Hi Vacuum Tube  

1.   General Information of  3 - hi vacuum tube:

Just like an automobile engine,the computer CPU,vacuum tube is the core component of the solar water heater. Its performance lies on the actual film coating technology.

When investing in solar technology, it is important to ensure the "engine" you select is the most powerful and the longest lasting made. This if why we use LUCKY patented "THREE-TARGET" vacuum tubes. The absorbing coating found on the inner layer determines how efficient the vacuum tube will operate. The method and material of this coating will also define the life expectancy of the vacuum tube.

Most vacuum tubes use a hi-tech reactive sputtering process to coat the inner tube. Most commonly this coating is made from aluminum and aluminum-nitrogen coating (Al-N/Al) which is the primary absorbing coating.

2. Advantages of  3 - hi vacuum tube :

Why 3 - hi vacuum tube ?

Vacuum (evacuated) tube works like well-known, a thermos flask, which uses vacuum to provide thermal insulation; once the evacuated tube absorbs the radiation from the sun and converts it to heat; the vacuum helps keep the heat.

The vacuum insulation makes evacuated tube collector excel the traditional flat plate collector in performance.

What are the main advantages of evacuated tube over flat plates collectors?

1. Increased efficiency: Due to the tabular shape of the evacuated tubes, the sun is always perpendicular to the surface of the glass for most of the day. Flat plate reaches maximum efficiency only at noon time.

2. Minimal heat loss: Since air is evacuated from the glass tubes to form a vacuum, it reduces the heat loss from the tube. This means that wind and colder temperatures have less effect on the collectors efficiency.

3. Freeze protection: Evacuated tube collectors can be used in freezing conditions without the system being damaged. Flat plates require more sophisticated antifreeze systems which increases maintenance costs and lowers efficiency.

3.  3 - hi vacuum tube Working Principle:

Thermo siphon Solar Water Heater relies on the natural circulation of water between the collector and the tank or heat exchanger. As water in the vacuum tubes is heated, it rises naturally into the elevated tank while cooler heavier water in the tank flows down to the bottom of the vacuum tubes, causing circulation throughout the system. Greater height differential will result in greater flow. Larger pipe, shorter runs, and gentle bends will make for an adequate flow rate.
