PROBLEM TO BE SOLVED: To provide a blower capable of performing the maximum performance and low noise by devising the geometry of the blower wheel, when the blower is retrofitted in thin equipment.SOLUTION: A fan cup 24 is provided with a disk 28, which is provided with blades 37. The blades 37 are not jointed to the fan cup 24, and the ratio of the inner diameter a of the blade 37 to the outer diameter b of the blade 37 is 60-45%. This is effective and achieves low noise in retrofit of thin equipment. |
