|Determining the Limits of Natural Convection Cooling for Hand-Held Consumer Electronics Products|
|Keywords: natural convection cooling limits, handheld devices, maximum touch temperature|
|With the rapidly increasing performance in tablets and smart phones, the result is increased power consumption leading to devices that are uncomfortably hot to hold. This is especially true since watching video or playing games on these devices has become very popular. The thermal design of the next generation handheld tablets and smart phones 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. This study explores the limits of cooling for handheld devices of various sizes and provides guidelines for maximizing the amount of power that can be dissipated in these small form-factor devices. This study presents methods for maximizing the internal power dissipation of these devices while limiting the touch temperatures to the maximum comfortable limits.|
