  • Impeller blade for axial flow fan having counter-rotating impellers
    Patent number: 6856941
    Abstract: Method for determining the camber line and thickness distribution for blades used in a cooling fan with counter-rotating impellers. The camber lines and thickness distributions for the blades of each of the impellers are determined through use of Bezier curves and chosen to reduce boundary layer separation of airflow across the blades. The Bezier control points are altered to produce a set of distributions of the camber lines and thickness distributions, and the most favorable set is found with increased cooling efficiency.

  • Axial flow fan having counter-rotating dual impeller blade arrangement
    Patent number: 6565334
    Abstract: A counter-rotating axial flow fan for cooling electronic components comprising two or more impellers with narrow chord blades. At least one impeller rotates in a first direction and at least one impeller rotates in a second direction opposite to the first direction. The blades of the impellers are configured so as to cause air to flow in the same axial direction. The air flow generated by this counter-rotating fan is substantially greater than the air flow of an otherwise identical co-rotating fan.
