Abstract
According to some embodiments, systems for improved blower fans are provided. In some embodiments, systems may include a casing comprising an inlet to accept a fluid and an outlet to evacuate the fluid. The systems may further comprise an impeller disposed within the casing, comprising a hub and one or more impeller blades coupled to the hub. In some embodiments, the inlet of the casing may be shaped to reduce the amount of fluid that evacuates the casing via the inlet due to pressure within the casing.
Claims13
A system, comprising:
- a casing comprising:
- an inlet defining portion defining an inlet to accept a fluid;
- and
- an outlet defining portion defining an outlet to evacuate the fluid;
- and
- an impeller disposed within the casing, comprising:
- a hub;
- and
- a plurality of impeller blades coupled to the hub, each impeller blade having an outer edge opposite the hub and an upper edge proximate the inlet;
- wherein each of the plurality of impeller blades comprises a tapered portion coupled to the hub, wherein a height of the outer edge is higher than a height of the tapered portion, wherein the casing defines an opening for the plurality of impeller blades, and wherein a portion of each of the plurality of impeller blades includes a notch shaped portion, and wherein a substantially perpendicular section of the casing extends into the notch shaped portion, to reduce the amount of fluid that evacuates the casing via the inlet due to pressure within the casing.
