shandong guangpu new patented high efficiency Solar Super Heat Conduction Collector Tube

shandong guangpu new patented high efficiency Solar Super Heat Conduction Collector Tube : 

Four-cavity Vacuum Solar Collector Tube’s Advantages:
 

1.Heat loss can be greatly cut down, so that the heat efficiency is improved.

The structure of the four-cavity tube is improved, an outer support (4) of the common tube in the picture 2 is updated to an inner support (5) of the four-cavity tube in the picture 1, the metallic bracket (5) doesn’t contact the outer tube (1), so that the heat loss channel is cut off, and the heat collecting efficiency of the collector tube is improved by 30 to 35 percent in general.

2.The water storage cavity is narrowed, less water is stored, water temperature rises much faster, and the heat

collecting property is improved.

Because the four-cavity tube is additionally provided with an inner cylinder tube, the water cavity of the four-cavity tube is reduced by 1/5 to 1/4 of that of the common tube, and just because the water in the water cavity is much reduced, the water temperature quickly rises, the water circulation is fast, and the heat collecting property is greatly improved.

3.The four-cavity tube is the neck shrinkage vacuum tube manufactured by adopting neck shrinkage technique on its orifice, and the heat collecting efficiency is improved.
