After ten years of research and production "Tiny Cooling Fan" summarizes the development of Chinese enterprises in 2012 in the field of cooling fan, fan blades and other faces. Which is one of the fan blades of the core components, parts magnitude of value from the point of view of the blade maximum magnitude of value, accounting for about 25% of the entire cost of the equipment; at the same time, "Tiny Cooling Fan" wind turbine blade industry is part of the uncertainty higher, the market capacity is large, clear profit model composites industry. Generator cooling fan blade production technology from foreign companies, according to the standards of foreign production, "Tiny Cooling Fan" raw materials imported from abroad, companies do not have independent research and innovation initiative. In the experimental development of the blade, design and manufacturing, production process, the mold Many of the key technology and equipment in China have failed to grasp.
