Ordinary solar three executives and Zijin tube in the structure of the heat absorption what difference ah help compare the best can bring the price comparison thank you
4, appearance: appearance color: ordinary tube and three high vacuum tube appearance color difference is not big. However, the two tubes of color difference is greater: with the naked eye observation, the three executives of the inner tube color is red (because the film layer is copper); and high efficiency tube or ordinary tube is white (because the film layer is aluminum).
The interference film is composed of 2 layers, and the interference between the two layers is caused by the difference of the composition of the metal, so that the absorption ratio is increased, and the emission ratio is reduced. In addition, the anti reflection layer can reduce the reflection effect, thereby achieving a higher absorption ratio and a lower emission ratio, which greatly improves the heat collection efficiency.2, features: three higher than the general manager of the tube to improve the absorption of 10-12%, emission ratio decreased by 30%, super absorption, less heat loss, warming up. Under the same illumination condition, the heat absorption of the common tube is less than three.
1, the fundamental difference: different film structure, leading to the principle of absorption of solar light is not the same.The gradual change film, for multilayer film, its absorption layer is generally 9 layers, it is absorbed by the solar light layer by layer, and its absorption of light performance gradually high. And the absorption of aluminum ions in the high temperature state, greatly enhanced the flexibility and may drift. Under the condition of high temperature in the long term, the film may fall off, which will affect the collector efficiency and life of the vacuum tube.
First, the general manager and the difference between three executives:The difference between ordinary tube and three high vacuum tube is that the heat absorbing film is different. The ordinary tube is a gradual film, and the third is the interference film. The main difference between them is the difference between the gradient film and the interference film.
