a device and method for dissipating heat from a source of heat is described . a plurality of layers of thermally conductive materials receives a flow of heat from a source of heat . a first layer of the plurality of layers receives the flow of heat from the source of heat and redirects and transfers the flow of heat to a second of the plurality of layers . each layer has a separate preselected thermal impedance to control a desired temperature change across the plurality of layers and to maintain a desired operating temperature of the source heat .
