11. A method of cooling an electromagnetic device comprising a core having first and second arms connected by a body with a first winding having multiple turns around said first arm and a second winding having multiple turns around said second arm comprising the steps of:
-
providing a plurality of heatsink elements each comprising a base having a first thickness and first and second legs having a second thickness less than the first thickness extending from the base, arranging a first one of the heatsink elements with the first leg of the first heatsink element between the first arm of the core and a portion of the first winding and the second leg of the first heatsink element between the second arm of the core and a portion of the second winding;
arranging a second one of the heatsink elements with the first leg of the second heatsink element between a first and a second turn of the first winding and the second leg of the second one of the heatsink elements between a first and a second turn of the second winding; and
holding the bases of the heatsink elements in thermal contact. - View Dependent Claims (12, 13, 14, 15, 16)

- 17. An electromagnetic device comprising a core having first and second arms connected by at least one body, a first winding comprising multiple turns on said first arm and a second winding comprising multiple turns on said second arm, and a heatsink comprising a first plurality of U-shaped heatsink elements each comprising first and second legs aligned with said first and second arms and having a first thickness connected by a base having a second thickness greater than said first thickness, the base of each of said plurality of elements being in contact with the base of an adjacent heatsink element.
- 23. A heatsink comprising a plurality of U-shaped heatsink elements each comprising first and second legs connected by a base and a plurality of spacers spacing the base of each heatsink element from the base of an adjacent heatsink element and leaving a gap between the first leg of each heatsink element and the first leg of an adjacent heatsink element, the base of each of said plurality of heatsink elements being in thermal contact with the base of each adjacent heatsink element through said spacers.
