If examine these "Micro Cooling Fan" "quality" indicators, China cooling fan manufacturers still in a backward state, domestic cooling fan frequently thrown quality problems, including the collapse of the whole leaf, spindle breakage, fire motor, gearbox damage, etc. , wind turbine manufacturers are also more or less domestic ranking thrown some quality problems, although not appearing malignant mass accident, but the main reason for allegedly not "Micro Cooling Fan" blower design and manufacturing sectors, but fans enterprises exist lack of core technology, governance is not in place for the competition for the market and the price war and other phenomena, it is difficult to say does not affect the quality of the cooling fan. Despite some domestic enterprises in the follow-up research and development and innovation, but a lot of "Micro Cooling Fan" to grasp the core technology is still in the hands of foreign enterprises.
