Abstract: An apparatus for a wireless power transfer (“WPT”) pad heat management system includes a ferrite structure positioned adjacent to a coil configured to wirelessly transfer power. The apparatus includes a plurality of heat spreaders positioned along a length of a component of the ferrite structure. Each of the plurality of heat spreaders is non-metallic. The apparatus includes a trough shaped to surround at least a portion of each of the plurality of heat spreaders, wherein the trough is non-metallic. The apparatus includes a phase change material (“PCM”) in the trough where at least a portion of the heat spreaders extend into the PCM. The ferrite structure, coil, plurality of heat spreaders, trough and PCM are encased in a solid material, and each of the plurality of heat spreaders comprises a material that transfers heat from the component of the ferrite structure to the PCM.
