A centrifugal blower apparatus includes a scroll-shaped housing with first and second air inlets which open to a blower chamber that is in fluid communication with an air outlet. The blower includes a motor to drive impellers, wherein the motor is secured to a frame coupled within the housing in a manner to substantially enhance aerodynamic performance of the blower.

A cooling system for an electronics chassis includes a plurality of centrifugal blowers arranged to motivate cooling air through the electronics chassis. The centrifugal blowers are arranged in one or more sets, each having blowers oriented with respective inlets in mutual facing relationship. The orientation, positioning, and alignment of the centrifugal blowers facilitates a compact arrangement of the plurality of blowers that achieves increased aerodynamic efficiencies to reduce noise output and energy consumption.

A centrifugal blower apparatus includes a scroll-shaped housing with first and second air inlets which open to a blower chamber that is in fluid communication with an air outlet. The blower includes a motor to drive an impeller, wherein the motor is secured to a frame that is coupled with the housing in a manner to substantially enhance aerodynamic performance of the blower.

Double inlet centrifugal blower with peripheral motor

A centrifugal blower having at least one radial plane dividing its scroll into sub-sections which may vary as to cut-off points and axial and radial dimensions as well as axial displacement to meet requirements of individual application system flow paths.
