Blower fan structure
摘要:
Provided is an improved blower fan structure in which length of blades is increased and inlet and outlet angles of the blades are optimized for highly increasing an efficiency of the blower fan. Particularly, an outer diameter of the blades is more than or equal to two times of an inner diameter thereof, for increasing the efficiency without generating a noise.
