Comparing Tablet Natural Convection Cooling Efficiency

White Paper: With the rapidly increasing performance of tablets and smart phones, the result is increased power consumption leading to devices that are uncomfortably hot to hold. This is especially true after watching videos or playing games on these devices has become very popular. These types of operations are both CPU and graphics intensive which involve much higher power dissipation than viewing a relatively static screen. The thermal design of the next generation handheld tablet device and smart phone will need to address both a comfortable surface touch temperature and maximum temperature limitations of critical internal components while also meeting aggressive industrial design requirements.
