CENTRIFUGAL BLOWER

PROBLEM TO BE SOLVED: To reduce the noise of a centrifugal blower by properly increasing passage cross sectional area. SOLUTION: The height(h) of an air passage is increased so that the passage cross sectional area S is increased exponentially. Thus, because the passage cross sectional area S is not...

Summary:PROBLEM TO BE SOLVED: To reduce the noise of a centrifugal blower by properly increasing passage cross sectional area. SOLUTION: The height(h) of an air passage is increased so that the passage cross sectional area S is increased exponentially. Thus, because the passage cross sectional area S is not increased rapidly on a winding end side, air flow is prevented from being disturbed at the winding end side so as to reduce the noise of the blower.
