Abstract: A system and method for cooling electric machines using direct winding heat exchangers (DWHX) is disclosed. The system can comprise a plurality of DWHXs disposed in thermal communication with a plurality of copper windings in the stator of an electric machine for cooling the plurality of copper windings. The plurality of DWHXs can also be in fluid communication with one or more fluid manifolds for providing coolant to the plurality of DWHXs. The one or more manifolds can be in fluid communication with one or more heat reservoirs for rejecting the heat absorbed by the plurality of DWHXs. The heat reservoir can be an internal system radiator or an infinite reservoir such as a cooling pond. The method can comprise a design tool for optimizing a DWHX cooling system utilizing the internal system radiator or an infinite reservoir, among other things.
