Abstract
An information handling system (IHS) includes a base station that has a transmitter coil to generate a magnetic field for charging a portable power source of a battery-powered electronic device. A receiver coil magnetically receives power from the transmitter coil of the base station. A power control module connected to the portable power source and the receiver coil charges the portable power source with the received power. A flexible ferrite shield is positioned on a side of the receiver coil opposite to the transmitter coil to shield the IHS electronics. A pneumatic diaphragm is formed by a portion of the flexible ferrite shield that is positioned for oscillating movement into a center cavity of the receiver coil. A diaphragm actuator is attached to the pneumatic diagram and is responsive to a triggering signal to oscillate the pneumatic diaphragm to disperse thermal energy that is generated by the receiver coil.
