Abstract

PURPOSE: To reduce air flow speed in the casing to decrease noise of a blower, by providing plural number of holes close to the wall portion of the casing along the circumferencial direction and also fluid resisting body having flow straightening and silencing performance at the exit of the flow passage.
CONSTITUTION: The air flow A3 flowing into the casing 1 accompanied with the rotation of the fan 4, flows, on the other hand as air flow A4 which passes the gap between the rotor 2a and the stator 2b acting as passage sectional area. On the other side, the flow is separated as the air flow B1 which flows out through plural number of holes 11 prepared at the position close to the wall portion 1a of the casing 1 along its circumference, then passes through the passage 13 provided on the outer circumference of the casing 1, and also through fluid resistance 14 installed in the passage 13, and the flow is straightened, silenced and flows out of the casing 1. Thus the gas speed in the casing 1 is reduced and the noise in the casing can be reduced.
