In recent years, "Micro Cooling Fan" industry has developed a range of efficient new DC fans, especially with the introduction of the digestion and improve the technology of the drums, heavy drums, Chengdu Power Machinery Plant DC fans, the advantage of the tunnel fan, Siping, weight through high-temperature DC fan, Beijing Xishan, Shen drum, drum fans and other industrial boilers gradually get user acceptance, which gives the plant a tremendous economic effect. But China still has a variety of inefficient old "Micro Cooling Fan" needs upgrading, promotion of new miniature fan can be further improved. Therefore, China should continue to improve product quality mini fan, stabilize the market demand, but also actively introduce advanced technology to improve technology development capability; to brand strategy, vigorously develop the market; economies of scale in order to promote the "Micro Cooling Fan" enterprise development.
