CENTRIFUGAL AIR BLOWER AND AUTOMOBILE SEAT |
摘要 |
A centrifugal multi-blade impeller (10) that has a plurality of blades (11) around a central axis of rotation (10a) and that radially outwardly blows air taken in along the central axis of rotation is housed in a spiral scroll casing (20). The ratio of H/D of height H of the centrifugal multi-blade impeller in a direction of the central axis of rotation to diameter D of the centrifugal multi-blade impeller is 0.2 or less. The scroll casing has a logarithmic spiral spread angle γ of 2.0 degrees or more. It is thereby possible to provide a small and low profile centrifugal air blower that has high air blowing performance and is low noise.
