Conformal heat pipe assemblies

A heat pipe assembly comprising:

• plural connected walls extending around interior chambers, the walls having porous wick linings along the walls that are configured to hold a liquid phase of a working fluid in the interior chambers, the walls forming elongated interior portions of the interior chambers that are located between neighboring conductive windings of a motor, the walls also forming elongated exterior portions of the interior chambers that are located outside the conductive windings of the motor;
• and
• an insulating layer coupled with at least one of the walls on a side of the at least one wall that is opposite of the porous wick lining of the at least one wall, the insulating layer of the at least one of the walls directly abutting at least one of the conductive windings of the motor such that heat from the conductive component vaporizes the working fluid in a first porous wick lining of the porous wick linings and a second porous wick lining of the porous wick linings receives a condensed phase of the working fluid that was vaporized to cool the conductive component of the electromagnetic device.
