As in recent years, new communities, affordable housing, protection of housing construction progress, urban demand for solar water heater (system) pressure over the countryside again, showing vigor, solar thermal market in the rural areas "popular" Ten years later again faced with the return of the city. Urban solar thermal market combined with the construction put forward higher requirements, whereby flat solar architecture combined with its easy and characteristics, as well as installation and design flexibility and savings on public irradiated area by the city of light and heat strong market favor. As in recent years, new communities, affordable housing, protection of housing construction progress, urban demand for solar water heater (system) pressure over the countryside again, showing vigor, solar thermal market in the rural areas "popular" Ten years later again faced with the return of the city. Urban solar thermal market combined with the construction put forward higher requirements, whereby flat solar architecture combined with its easy and characteristics, as well as installation and design flexibility and savings on public irradiated area by the city of light and heat strong market favor. Restricted solar industry technology breakthrough "very difficult" However, the development of solar energy companies in the decades before the mostly interest-oriented emphasis on the development and production of the relatively low technical threshold and is popular in the countryside of the vacuum tube solar water heaters, only a few companies adhere to flat plate solar breakthrough research and technologies. So, faced with now quickly pick up the urban market, many solar companies seem "very difficult", wants to expand the urban market but because of the flat plate solar technology threshold, only to seek cooperation with the flat solar companies or temporary launched, construction of flat solar production lines. China's solar thermal industry leading level in the world, but only in the vacuum tube solar water heaters, solar flat cutting-edge technology has been monopolized by European countries, which makes China's flat panel solar energy industry development is limited, and difficult to open pattern in the international arena. Collector flat solar collector performance is not the problem, then China's flat solar and flat solar overseas is worse off? On the one hand is a big difference in the welding and coating process flat plate solar collectors. Welding process aspects, confronted in the production of flat solar collectors with flat stitching and welding their welded connections collector and the heat pipe, a good flat solar products, not only to have excellent collector performance, but also through effective heat transfer medium heat transfer to the water in order to ultimately reflect its value. China's flat panel solar products over the years to take the traditional welding methods, not only inefficient, but also energy consumption, resulting in substantial waste of raw materials and energy, most of the products produced quality does not pass, the failure, high cost. At the same time, the core of flat solar coating technology and advanced welding process is controlled by the United States, Germany and other European countries in the hands of the few, and by the monopoly, China's flat panel solar companies and research capacity is insufficient to solve these technical problems, thereby becoming Chinese flat solar industry over the years can not get the reason for massive expansion. On the one hand is the construction of a new city brings wireless life, on the one hand is the lack of industry technology breakthrough capacity is limited due to, in order to seize the opportunity to achieve industrial upgrading, and then on the national and international market opportunities to win, technical issues be placed in in front of the biggest challenges. Break down the barriers "Made in China" is well known to achieve mass production of ultrasonic metal welding, equipment upgrades is a key constraint solar industry and an important aspect of the overall upgrade, upgrade the industry face many difficulties, recently the only ultrasonic metal welding equipment manufacturer Foshan Shunde Chu Xin Electrical Co., Ltd. a fully automatic whole plate ultrasonic welding metal roll group of products available to attract strong attention from the industry. The entire board seam welding is reported that this new automatic roll by the entire board Chuxin electromechanical developed the production of ultrasonic metal welder group, specifically applied to flat solar absorber plate. Its generator circuit uses the world's most advanced the PLL frequency automatic tracking technology (such as AMTECH, STAPLA, TELSONIC are using this technology), the replacement of mold and work without FM. Continuously adjustable output amplitude, to achieve welding of copper and aluminum on the same device; its nominal power 3.6KW, the actual power capacity of 5.4KW, under the same operating conditions, the power capacity higher than domestic counterparts average power capacity 3 times; unique transducer manufacturing process to ensure high quality transducer. 20kHz transducer, can withstand more loads 5kw, solar absorber plate for welding, retain sufficient power capacity, to ensure maximum stability; high quality alloy steel welding head, life and manufacturing precision comparable to similar products in Europe and America; control The system uses PLC programmable touch screen control, with welding energy, time and height of three basic control modes, to meet the different needs of a variety of quality control software; In addition, almost all of the machined surface have carried out grinding and electroplating process, high precision machining, machine frame structural stability. By further understanding that, as early as 2007 by the Electrical and Mechanical Xin Chu developed the first generation of ultrasonic metal welding equipment unit had come out, breaking the Europe of ultrasonic welding technology monopoly, the first in China to achieve a breakthrough in ultrasonic metal welding technology and practical application. But then the metal wave ultrasonic welding technology to be applied only in a small number of flat solar companies, such as Guangdong Five-Star Solar, along with nearly two years to develop flat-panel solar energy industry, the advantages of ultrasonic metal welding technology only lead to more business concerns. The advent of solar energy seam welding sample by Chu Xin mechanical and electrical self-developed automatic whole plate ultrasonic welding metal roll group on the basis of the first generation of products based on the realization of the "semi-mechanization" to "fully mechanized" upgrade, unit equipment only can significantly increase productivity, save labor costs, but also reduce energy consumption, save raw materials, excellent quality of products, less failure, low cost. Authoritative experts said the new ultrasonic metal welding technology not only can effectively solve the high cost of China welding industry problems, but also greatly improve the technical level of domestic ultrasonic metal welding, ultrasonic metal welding marks China's R & D capabilities, manufacturing capacity We have entered the ranks of leading international.
