Abstract
A centrifugal blower assembly comprises a scroll wall and a pair of opposing sidewalls. The scroll wall is positioned between the pair of opposing sidewalls such that the scroll wall and opposing sidewalls together define a blower chamber and a blower outlet. A baffle element is positioned within the blower chamber and adjacent the blower outlet such that the baffle element is configured to facilitate uniform distribution of airflow downstream of the blower assembly. An air stream splitter is coupled to the scroll wall. The air stream splitter includes a spline member extending a varying distance from the scroll wall. The air stream splitter is positioned within the blower chamber to facilitate uniform airflow distribution within the blower assembly.

A centrifugal blower assembly comprising:
- a scroll wall and a pair of opposing sidewalls, said scroll wall positioned between said pair of opposing sidewalls such that said scroll wall and said pair of opposing sidewalls define a blower chamber and a blower outlet;
- a baffle element positioned within said blower chamber adjacent the blower outlet;
- and
- an air stream splitter coupled to said scroll wall, said air stream splitter comprising a spline member extending a varying distance from said scroll wall, wherein said air stream splitter is positioned to facilitate uniform airflow distribution within said blower assembly.
An air stream splitter for use in a centrifugal blower assembly, said air stream splitter comprising a spline member coupled to a scroll wall of the blower assembly, said spline member extending a varying distance from the scroll wall, and wherein said spline member is perpendicular to the scroll wall and is positioned to facilitate uniform airflow distribution within the blower assembly.
A method of assembling a centrifugal blower assembly, said method comprising:
- positioning a scroll wall between a pair of opposing side walls to define a blower chamber and a blower outlet;
- positioning a baffle element within the blower chamber and adjacent the blower outlet such that the baffle element is configured to facilitate uniform distribution of airflow downstream of the blower assembly;
- and
- coupling an air stream splitter to the scroll wall at a pre-determined location within the blower chamber to facilitate uniform airflow distribution within the blower assembly, wherein the air stream splitter includes a spline member that extends a varying distance from the scroll wall.
