Increasingly Dense Mobile Devices Present Cooling Challenges in Product Design

   As mobile devices get more sophisticated in their functionality, they are packing greater amounts of internal electronics — heat-producing electronics. It’s up to mobile device designers to find ways to dissipate heat efficiently. While there are several passive-cooling methods, active cooling might be essential in the future.



sophisticated adjective
