"Micro Cooling Fan" first use of raw materials, there are still many shortcomings compared to the cooling fan of the mold and abroad; followed by manufacturing technology, due to the technology behind the development of China cooling fan industry is greatly hindered, it has become a major bottleneck cooling fan industry development; again is the cooling fan system is not fully supporting another big hinder its development. "Micro Cooling Fan" It is these problems largely restricted the development of China's cooling fan industry. Therefore, China's cooling fan industry want better development, we must remove these stumbling blocks. In recent years, "Micro Cooling Fan" industry experienced hardships along the way, affected by the economic crisis, although the overall growth is slowing, but still made a lot of achievements, significantly improved the overall strength of the industry level.
