Abstract

A cooling device for use with an engine is provided. The cooling device includes a flow control portion that includes a base and an opening defined therein. The flow control portion also includes a plurality of blades that extend from at least a portion of the base. The cooling device also includes a grid portion having an opening defined therein, said grid portion opening is substantially concentrically aligned with the base opening. An attachment portion is configured to couple the cooling device to at least one rotatable component of the engine. Each of the flow control portion, the grid portion, and the attachment portion are formed integrally together such that the cooling device is a single component.

First claim

What is claimed is:

1. A cooling device for use with an engine, said cooling device comprising:
a flow control portion comprising an annular base having an opening defined therein, said flow control portion further comprises a plurality of blades extending radially inward from at least a portion of said annular base such that a flowpath is defined through said opening and past said plurality of blades;
a grid portion comprising an opening defined therein, said grid portion opening is substantially concentrically aligned with said base opening; and
an attachment portion extending at least partially through said base opening and said grid portion opening, wherein said attachment portion comprises a plurality of flanges spaced circumferentially about a centerline of said attachment portion, and at least one fastener opening positioned radially outward from said plurality of flanges, said attachment portion formed integrally with said flow control portion and said grid portion, wherein said at least one fastener opening is sized to receive a fastener therethrough.

2. A cooling device in accordance with claim 1 , wherein said grid portion extends from at least a portion of each of said plurality of blades.

3. A cooling device in accordance with claim 1 , wherein each of said plurality of blades are spaced substantially uniformly with respect to each other.

4. A cooling device in accordance with claim 1 , wherein each of said plurality of blades are spaced substantially non-uniformly with respect to each other.

5. A cooling device in accordance with claim 1 , wherein at least one of said plurality of blades comprises a shape that is different than a shape of the remaining of said plurality of blades.

6. A cooling device in accordance with claim 1 , wherein said grid portion comprises a plurality of first fan blades and a plurality of second fan blades, said first plurality of fan blades extend radially outwardly from said grid portion opening, each of said plurality of second fan blades are oriented substantially perpendicularly to said plurality of first fan blades.

7. A cooling device in accordance with claim 6 , wherein each of said plurality of first fan blades comprises at least one of a substantially rectangular shape, a substantially elliptical shape, and a substantially airfoil shape.

8. An engine comprising:
a rotatable shaft;
an adaptor plate coupled to said rotatable shaft, said adaptor plate comprises a surface comprising a first portion and a second portion, said first portion extends substantially curvilinearly towards said second portion to facilitate defining a flow path within said engine; and
a cooling device coupled to said rotatable shaft and to said adaptor plate such that said cooling device is positioned against at least a portion of said adaptor plate surface to enable fluid to be channeled from said adaptor plate surface to said cooling device via the flow path, said cooling device comprises a flow control portion, a grid portion, and an attachment portion, said flow control portion comprises an opening defined therein and a plurality of blades extending outward from said opening, said opening is sized to receive at least a portion of said adaptor plate therein, said grid portion comprises an opening defined therein and said grid portion opening is substantially concentrically aligned with said flow control portion opening, said attachment portion comprising a plurality of flanges spaced circumferentially about a centerline of said attachment portion, and at least one fastener opening positioned radially outward from said plurality of flanges, said attachment portion is configured to couple said cooling device to said rotatable shaft.

9. An engine in accordance with claim 8 , wherein said adaptor plate comprises at least one opening defined therein, at least a portion of said rotatable shaft extends through said adaptor plate opening.

10. An engine in accordance with claim 8 , wherein said grid portion extends from at least a portion of each of said plurality of blades.

11. An engine in accordance with claim 8 , wherein each of said plurality of blades are spaced substantially uniformly with respect to each other about said flow control portion.

12. An engine in accordance with claim 8 , wherein each of said plurality of blades are spaced substantially non-uniformly with respect to each other about said flow control portion.

13. An engine in accordance with claim 8 , wherein at least one of said plurality of blades comprises a shape that is different than a shape of at least one other of said plurality of blades.

14. An engine in accordance with claim 8 , wherein said grid portion comprises a plurality of first fan blades that extend radially outwardly from said grid portion opening and a plurality of second fan blades that are each oriented substantially perpendicular to said plurality of first fan blades.

15. An engine in accordance with claim 8 , wherein each of said plurality of first fan blades comprises at least one of a substantially rectangular shape, a substantially elliptical shape, and a substantially airfoil shape.

16. A cooling device for use with an engine, said cooling device comprising:
a flow control portion comprising an annular base having an opening defined therein, said flow control portion further comprises a plurality of blades extending radially inward from said annular base such that a flowpath is defined through said opening and past said plurality of blades;
a grid portion comprising an opening defined therein, said grid portion formed integrally with said flow control portion, said grid portion comprises a plurality of first fan blades that extend radially outwardly from said grid portion opening and a plurality of second fan blades that are substantially perpendicular to said plurality of first fan blades, said cooling device configured to rotate to provide cooling flow to facilitate cooling the engine; and
an attachment portion formed integrally with said grid portion and said flow control portion, said attachment portion comprising a plurality of flanges spaced circumferentially about a centerline of said attachment portion, and at least one fastener opening positioned radially outward from said plurality of flanges, wherein said at least one fastener opening is sized to receive a fastener therethrough.

17. A cooling device in accordance with claim 16 , wherein each of said plurality of flow control portion blades are spaced substantially non-uniformly with respect to each other.

18. A cooling device in accordance with claim 16 , wherein at least a first of said plurality of flow control portion blades comprises a shape that is different than a shape of at least a second of said plurality of flow control portion blades.

19. A cooling device in accordance with claim 16 , wherein each of said plurality of first fan blades comprises at least one of a substantially rectangular shape, a substantially oval shape, and a substantially airfoil shape.
