Product Description: three high target solar vacuum tube


vacuum tube

Evacuated tubes are the absorber of the solar water heater. They absorb solar energy converting it into heat for use in water heating. Evacuated tubes have already been used for years in Germany, Canada, China and the UK. There are several types of evacuated tubes in use in the solar industry. Use the most common "twin-glass tube". This type of tube is chosen for its reliability, performance and low manufacturing cost.

Each evacuated tube consists of two glass tubes made from extremely strong borosilicate glass. The outer tube is transparent allowing light rays to pass through with minimal reflection. The inner tube is coated with a special selective coating (Al-N/Al) which features excellent solar radiation absorption and minimal reflection properties. The top of the two tubes are fused together and the air contained in the space between the two layers of glass is pumped out while exposing the tube to high temperatures. This "evacuation" of the gasses forms a vacuum, which is an important factor in the performance of the evacuated tubes.

Features:
1) Higher heat efficiency: Advanced heat transferring style of the heat pipe
Heat transfer speed above the 10, 000 multiple of copper
2) Working without water inner tubes
3) Made of New tr-element vacuum tube .

Heat-pipe collector, the condenser zone of the heat-pipe is inserted to the copper sleeves which are distributed on the water pipe averagely. After the solar energy is absorbed by the vacuum tubes, it is transferred to the heat-pipe through the aluminum fin. Heated by the energy, the medium in the heat-pipe is working and transferring the heat energy to the condenser zone. When water or other medium in the water pipe flows across the copper sleeves, they would bring the energy and be heated
