Hi Guys,
Not sure exactly where to place this, it isn't per-say a question but more of an open discussion.
Obviously there are no fans or liquid cooling systems (that would require a pump and radiator) in our smartphones (I'm speaking in general, most modern smartphones do not have this with one exception being this rumor )
This leaves one last theory for removing heat from a small device, heatsinks. From my understanding, a heatsink is a type of material that is designed to disperse heat across its surface, so that it does not build up in one spot. In the US Galaxy S3 it has a Snapdragon Dual Core processor with a clock speed of 1.5 GHz which, while optimized to produce as little heat as possible, generates quite a lot of heat. Another source of heat is the battery, which as far as I can tell is not thermally connected very well.
A heatsink requires a technique called Thermal Coupling, where you connect the heat source directly to the sink with some sort of thermal isolating compound (this prevents the heat from going anywhere but into the sink), from this point the heat travels into the wide surface area (in the case of other phones I've taken apart, it is a square piece of aluminum on top of the processor), then it is dispersed into "arms" coming off the sink - this is why every surface of the phone feels hot and not just in one section.
With this information in mind, how do you think we can keep the device cool without adding additional components or modifying the phone at all? (ie. removing heat from the surface of the device)
