A thermodynamic heat exchanger is an electronic device having one or more heat generating devices, a heat exchanging element, and one or more heat exhaust elements. The heat generating devices can be the active and passive electronics elements included within a power conversion circuit, such as a power adapter used to charge a cellular telephone or other type of consumer electronics device. The heat exchanging element is configured to accept radiated thermal energy from the heat generating devices and distribute the accepted thermal energy across an outer surface to evenly distribute hot spots corresponding to the individual heat generating devices. The heat exchanging element is also configured to minimize heat radiating from its outer surface, thereby blocking heat in the thickness of the thermally conductive material.

A power supply adapter is provided. The power supply adapter includes a power converter circuit configured to generate a regulated voltage signal. The power converter circuit includes a rectifier coupled with AC power blades. A regulator circuit is coupled with the rectifier. A transformer is coupled with the regulator circuit. The transformer includes a primary and a secondary. The transformer is coupled with the regulator circuit via the primary. An output circuit is coupled with the secondary of the transformer. The output circuit includes an output capacitor. A flexible contact is coupled with each of a first and a second printed circuit board and flexibly biased to couple with a proximate end of the AC power blades. The adapter includes an EMI shield substantially surrounding a connector receptacle. The power converter circuit can include a forward or a flyback power converter. The transformer can include a planar format transformer coupled with the first or the second PCB. The transformer can include a metallic core of a ferrite material. The transformer core can be coupled with the EMI shield to provide thermal spreading. The adapter can include an enclosure for housing the power converter circuit. The enclosure includes a thermally conductive potting material substantially filling an empty space of an interior of the enclosure.
