Abstract
A double walled stator housing includes a first stator housing wall, a second stator housing wall located radially outward from the first stator housing wall, and an air gap located between the first and the second stator housing walls. The housing also includes at least one support structure attached to the first stator housing wall and the second stator housing wall, spanning the air gap and configured to minimize heat transfer between the first wall and the second wall.
Claims11
A double walled stator housing, the double walled stator housing comprising:
- a first stator housing wall;
- a second stator housing wall located radially outward from the first stator housing wall;
- an air gap located between the first and the second stator housing walls;
- and
- a plurality of support structures attached to the first stator housing wall and the second stator housing wall, spanning the air gap and configured to minimize heat transfer between the first stator housing wall and the second stator housing wall;
- wherein the plurality of support structures comprises a lattice network formed of a repeating network of spar assemblies, each spar assembly comprising a plurality of spars radially extending from a center point of the spar assembly such that each spar extends from the center point to an external spar end, and each spar assembly forming a cubic shape defined by each external spar end.
A method of manufacturing a double walled stator housing, the method comprising:
- manufacturing a first stator housing wall;
- manufacturing a second stator housing wall located radially outward from the first stator housing wall, wherein the first stator housing wall and the second stator housing wall define an air gap;
- and
- manufacturing a plurality of support structures attached to the first stator housing wall and the second stator housing wall, spanning the air gap and configured to minimize heat transfer between the first stator housing wall and the second stator housing wall;
- wherein the plurality of support structures comprises a lattice network formed of a repeating network of spar assemblies, each spar assembly comprising a plurality of spars radially extending from a center point of the spar assembly such that each spar extends from the center point to an external spar end, and each spar assembly forming a cubic shape defined by each external spar end.
