Introduced into the high-strength corrugated pipe
Recently, the Beijing Science and Technology Co., Ltd. into the strong (strong into solar) launched its new series of solar water heater core strength, the series is equipped with three executives in the ordinary glass vacuum tube based on the modified outer tube over the high-intensity and efficient corrugated tube.
At present, China\\ s solar water heater on the market of many manufacturers of solar products are all-glass vacuum tube-driven, and most of the products with a glass vacuum tube solar places three executives majority. Recently, the Beijing Science and Technology Co., Ltd. into the strong (strong into solar) launched its new series of solar water heater core strength, the series is equipped with three executives in the ordinary glass vacuum tube based on the modified outer tube over the high-intensity and efficient corrugated tube.
Solar tubes are generally divided into normal control and three executives, the biggest difference between the two heat-absorbing film is not the same, the three executives is the interference film, and general management is the gradient film. Film structure is different, leading to absorb the sun\\ s rays is not the same principle. Gradient film for multilayer films, the absorption layer is generally 9-layer, it is layer by layer to absorb the sun\\ s rays, and the performance of its absorption of light gradually becomes higher. Because of this gradient structure, the emission ratio increasing with increasing temperature, resulting in an operating temperature of 300 ~ 500 ?, the emission ratio increased significantly. And the absorption layer of aluminum ions in the high temperature state, the lively greatly enhanced, and drift. This film\\ s internal structure disorder, resulting in the film begin to age. Such a long period under high temperature, the film will fall off, thus affecting the vacuum tube collector efficiency and life. Interference film, the absorption layer 2 layer between two layers of film, because of the metal composition ratio of difference in the interference effect than increasing the absorption, emission than the lower. Coupled with anti-reflective layer to reduce the role of reflection in order to achieve higher and lower emission than absorption ratio, greatly improving the collection efficiency.
Strong into the core strength of the bellows with a series of three executives is based on the inner wall of the outer tube structure was modified so that in general three executives with high temperature, anti-cold at the same time have high absorption thermal efficiency and high strength characteristics. High-corrugated pipe in ordinary three executives, based on the uniform outer tube wall increased 18 special shape of the stripes, stripes and stripes will be formed between certain degree of curvature, convex mirror to achieve the effect of radiation from the sun into to the convergence effect, so as to enhance the absorption efficiency of the vacuum tube. In addition, each protruding stripes are able to play the role of mechanics in the support frame so that the outer tube of the shock tube is greatly enhanced, thus substantially increase the and the safety of the machine.
