<p>PROBLEM TO BE SOLVED: To improve static pressure efficiency of a blower having stator blades at downstream side of a fan.SOLUTION: A blower of this invention comprises a fan rotated in a prescribed direction around a rotary shaft C and a plurality of static blades installed in a radial manner around the rotary shaft C at a downstream side of an advancing direction of air flow generated through rotation of the fan and curved to opposite side of a fan rotating direction as they extend from the inner peripheral part to the outer peripheral part. The static blades 60 are constituted in such a way that an inlet angleθ1 formed by an inlet edge 601 where air flows in and by the rotary shaft C and a blade chord angle formed by a blade chord connecting an outlet edge 602 where air flow is discharged out with the inlet edge 601 and the rotary shaft C show larger values at the inner peripheral part and the outer peripheral part as compared with that of the radial central part.</p> |
