The U.S. Patent and Trademark Office published an Apple patent on Tuesday. This patent is mainly a heat dissipation system that can blow ion wind or ionized air from electronic devices. The built-in electromagnetic field controls its blowing path, which is most needed The cooling position provides a dynamically adjustable cooling method.
Apple U.S. Patent No. 8,305,728, entitled "Method and Apparatus for Cooling Electronic Equipment", describes a technique for controlling the blowing direction and path of ion wind in electronic equipment through a magnetic field. The main contemporary heat dissipation technology is the air flow caused by a mechanical fan, and then the wind is sent out inside the computer in a predetermined path. Many passive heat exchangers are used and finally discharged through the exhaust holes.
Apple's heat dissipation system uses an ion wind generator, based on a solid-state air booster, to perform corona discharge, discharge electricity next to the charged conductor, and the surrounding air produces ionization. The whole system consists of corona electrodes, electron collectors and high-voltage power supply. After the voltage is applied to the click, the electric field is generated, and the surrounding air particles are charged and ionized. The electric field pushes the charged particles to the collector and repels other neutral particles, forming a large amount of air flow.
