Abstract: A heat pipe assembly includes walls having porous wick linings, an insulating layer coupled with at least one of the walls, and an interior chamber sealed by the walls. The linings hold a liquid phase of a working fluid in the interior chamber. The insulating layer is directly against a conductive component of an electromagnetic power conversion device such that heat from the conductive component vaporizes the working fluid in the porous wick lining of the at least one wall and the working fluid condenses at or within the porous wick lining of at least one other wall to cool the conductive component of the electromagnetic power conversion device. The assembly can be placed in direct contact with the device while the device is operating and/or experiencing time-varying magnetic fields that cause the device to operate.

Abstract: A cooling assembly includes a body configured to be placed into thermal contact with a heat source and one or more non-planar, hermetic walls disposed within the body. The one or more non-planar hermetic walls extending around, enclosing, and defining a cooling channel configured to carry cooling fluid through the body such that the cooling fluid contacts internal surfaces of the cooling channel inside the body. The assembly including one or more enhancement structures disposed within the body and coupled with the one or more non-planar hermetic walls. The one or more enhancement structures shaped to change a flow path of the cooling fluid as the cooling fluid moves within the cooling channel and shaped to increase a surface area contacted by the cooling fluid within the cooling channel.
