Few days ago Apple filed 4 patents about methods of cooling its devices. Company's products have never been known for the problems of overheating but we can definitely assume that new versions will be more power hungry and thereafter more heat consumable in the future.

This is a list of new patents:

• “Methods and Apparatus for Cooling Electronic Devices Using Flow Sensors”.

The technology is about using sensors that determine air velocity in a device to adjust the fan speeds and computing power.

• “Methods and Apparatus for Cooling Electronic Devices Through User Interfaces”.

The patent describes using input/output ports to increase airflow through a device.

• “Methods and Apparatus for Cooling Electronic Devices Using Conductive Hinge Assemblies”.

The talk is about using notebook screen's hinges as heat exchangers.

• “Methods and Apparatus for Cooling Electronic Devices using Thermoelectric Cooling Components”.

The document explains using Peltier Effect for active components cooling.
