|Cooling Efficiency of Popular Tablets in a Natural Convection Environment|
|Keywords: Tablet Cooling Limits, Natural Convection Cooling, Tablet Cooling Efficiency|
|This study explores the limits of natural convection cooling for handheld devices based on both testing and simulation and proposes a figure of merit for the efficiency of heat dissipation. In most cases, the limiting factor in the thermal design of these devices is not the temperatures of the internal components but the temperature of the external surfaces since these are in direct contact with the skin of the user. There have been studies that address the maximum allowable comfortable touch temperature of a handheld device. This study presents a method for analyzing the quality of the thermal design of these devices. The study presents the results of testing four popular tablets under similar conditions of computational and graphical stress and compares their natural convection thermal solutions against each other and to the theoretical optimum thermal design for their size.|
