AppleInsider writes today that it has discovered a patent filing from Apple that shows that the company has been thinking about the possibility of putting mechanical fans in iOS devices such as the iPhone and iPad, with a view to cooling down the heat from the ever more powerful processors inside the devices. The fan that Apple has devised, according to the patent, is titled â€œCooling system for mobile electronic devices,â€ and reveals a motor being used to power a fan and an alert device. The diagrams show, among other things, how the motor is used to drive a fan to dispel the heat inside the device by â€œexchanging air between an inner cavity of the mobile computing device and an outer environment.â€ The alert device inside the phone or iPad is in turn driven by a clutch and drum mechanic, which enables the same motor to drive the device. No clue as to whether or not Apple intends to actually manufacture this, but for now it makes interesting reading.
