Abstract
Official abstract text for this publication.
A magnetic assembly includes a winding and a housing disposed about the winding. The housing includes an interior surface contoured to conform to the winding to facilitate heat transfer between the winding and the housing. A method of manufacturing a magnetic assembly includes forming a contoured interior surface on a housing and assembling a winding into the housing such that the interior surface of the housing conforms to the winding to facilitate heat transfer between the winding and the housing.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of manufacturing a magnetic assembly comprising: determining an outer contour of a winding by three-dimensionally scanning the outer contour of the winding; forming a contoured interior surface on a housing; and assembling the winding into the housing such that the interior surface of the housing conforms to the winding to facilitate heat transfer between the winding and the housing. 2. A method as recited in claim 1 , further comprising: determining the outer contour of the winding, wherein forming a contoured interior surface includes forming the contoured interior surface to have a substantially constant gap width between the winding and the interior surface. 3. A method as recited in claim 2 , further comprising: further comprising disposing potting material between the winding and the interior surface of the housing for electrical insulation between the winding and the housing and for thermal conduction between the winding and the housing. 4. A method as recited in claim 1 , further comprising: determining the outer contour of the winding, wherein forming a contoured interior surface includes forming the contoured interior surface to match the contour determined for the winding. 5. A method as recited in claim 1 , wherein forming the contoured interior surface includes forming the contoured interior surface to conform to individual strands of the winding. 6. A method as recited in claim 1 , wherein forming the contoured interior surface includes using additive manufacturing to form the contoured interior surface based on the outer contour determined. 7. A method as recited in claim 1 , wherein forming the contoured interior surface includes using computer numerical control (CNC) machining to form the contoured interior surface based on the outer contour determined. 8. A method of manufacturing a magnetic assembly comprising: determining an outer contour of a winding by three-dimensionally scanning the outer contour of the winding; forming a contoured interior surface on a housing; assembling the winding into the housing such that the interior surface of the housing conforms to the winding to facilitate heat transfer between the winding and the housing; and determining the outer contour of the winding, wherein forming a contoured interior surface includes forming the contoured interior surface to have a substantially constant gap width between the winding and the interior surface, wherein forming the contoured interior surface includes forming the contoured interior surface to conform to individual strands of the winding. 9. A method as recited in claim 8 , further comprising: further comprising disposing potting material between the winding and the interior surface of the housing for electrical insulation between the winding and the housing and for thermal conduction between the winding and the housing. 10. A method as recited in claim 8 , further comprising: determining the outer contour of the winding, wherein forming a contoured interior surface includes forming the contoured interior surface to match the contour determined for the winding. 11. A method as recited in claim 8 , wherein forming the contoured interior surface includes using additive manufacturing to form the contoured interior surface based on the outer contour determined. 12. A method as recited in claim 8 , wherein forming the contoured interior surface includes using computer numerical control (CNC) machining to form the contoured interior surface based on the outer contour determined.
