Abstract
A media device includes at least one piezoelectric fan selectively located to draw or urge air past one or more electrical components, such as an integrated circuit chip. Preferably, the piezoelectric fan is located within a channel milled or otherwise formed in the chip, however the fan may be located proximate the channel yet in fluid communication therewith. The piezoelectric fan operates to convectively cool the electrical component and may also prevent heat that has been generated by the electrical component from moving toward another electrical component within the media device. Thus, the configuration and location of the piezoelectric fan may advantageously cool one component while preventing heat energy from building up around one or more other components mounted nearby.
