AXIAL BLOWER AND SERIES-TYPE AXIAL BLOWER
摘要:
An axial blower includes: a housing including a wind tunnel; an impeller that is disposed in the wind tunnel and includes a plurality of blades; and a motor that includes a rotation shaft and is secured to the housing, the impeller being secured to the rotation shaft. When an angle between a chord of the blade at a cross-sectional surface of the blade cut by a virtual cylindrical surface centering the rotation shaft, and a surface perpendicular to the rotation shaft is defined as a mounting angle, the blade includes an intermediate part between an inside diameter side part and an outside diameter side part of the blade, and this intermediate part has a mounting angle equal to or larger than a mounting angle of the inside diameter side part, and larger than a mounting angle of the outside diameter side part.
