Abstract

A housing for a generator assembly can include an outer housing shell configured to enclose a plurality of generator components and a stator baffle disposed within the outer housing shell at a distance from an inner surface of the outer housing shell to form an air gap between the stator baffle and the outer housing shell to thermally insulate the plurality of generator components. The stator baffle can be configured to mount to a stator assembly of the generator components.

Claims (30)

1 . A housing for a generator assembly, comprising:

an outer housing shell configured to enclose a plurality of generator components; and

a stator baffle disposed completely within the outer housing shell at a distance from an inner surface of the outer housing shell to form an air gap between the stator baffle and the outer housing shell to thermally insulate the plurality of generator components, the stator baffle configured to mount to a stator assembly of the plurality of generator components.

2 . The housing of claim 1 , wherein the stator baffle has a cylindrical hoop shape.

3 . The housing of claim 1 , wherein the stator baffle is connected to the inner surface of the outer housing shell by one or more supports.

4 . The housing of claim 3 , wherein the one or more supports include a tapering shape configured to have less cross-sectional area at the inner surface of the outer housing shell than at the stator baffle.

5 . The housing of claim 4 , wherein the one or more supports include curved sides.

6 . The housing of claim 3 , wherein at least one of the one or more supports is configured to house one or more fluid and/or electrical lines to pass through from the outer housing shell to the stator baffle.

7 . The housing of claim 1 , wherein the housing is made of a titanium alloy.

8 . A generator assembly for a high temperature environment, comprising:

a housing comprising:

an outer housing shell configured to enclose a plurality of generator components; and

a stator baffle disposed completely within the outer housing shell at a distance from an inner surface of the outer housing shell to form an air gap between the stator baffle and the outer housing shell to thermally insulate the plurality of generator components, the stator baffle configured to mount to a stator assembly of the plurality of generator components.

9 . The assembly of claim 8 , wherein the stator baffle has a cylindrical hoop shape.

10 . The assembly of claim 8 , wherein the stator baffle is connected to the inner surface of the outer housing shell by one or more supports.

11 . The assembly of claim 10 , wherein the one or more supports include a tapering shape configured to have less cross-sectional area at the inner surface of the outer housing shell than at the stator baffle.

12 . The assembly of claim 11 , wherein the one or more supports include curved sides.

13 . The assembly of claim 10 , wherein at least one of the one or more supports is configured to house one or more fluid and/or electrical lines to pass through from the outer housing shell to the stator baffle.

14 . The assembly of claim 10 , wherein the housing is made of a titanium alloy.

15 . A turbomachine, comprising:

a tail cone downstream of a hot turbine; and

a generator assembly disposed in the tail cone and comprising:

a housing comprising:

an outer housing shell configured to enclose a plurality of generator components; and

a stator baffle disposed completely within the outer housing shell at a distance from an inner surface of the outer housing shell to form an air gap between the stator baffle and the outer housing shell to thermally insulate the plurality of generator components, the stator baffle configured to mount to a stator assembly of the plurality of generator components.

16 . The turbomachine of claim 15 , wherein the stator baffle has a cylindrical hoop shape.

17 . The turbomachine of claim 15 , wherein the stator baffle is connected to the inner surface of the outer housing shell by one or more supports.

18 . The turbomachine of claim 17 , wherein the one or more supports include a tapering shape configured to have less cross-sectional area at the inner surface of the outer housing shell than at the stator baffle.

19 . The turbomachine of claim 18 , wherein the one or more supports include curved sides.

20 . The turbomachine of claim 17 , wherein at least one of the one or more supports is configured to house one or more fluid and/or electrical lines to pass through from the outer housing shell to the stator baffle.
