Apple granted patent for ionic cooling system

Apple has been granted a patent (number 8305728) by the U.S. Patent & Trademark Office for a . It involves a cooling system that blows ionized air through an electronic device, controlling its path by creating electromagnetic fields that can be dynamically adjusted to direct cooling where it's needed.

Embodiments provide various apparatus and techniques for deflecting or redirecting a flow of ionized air generated from an ionic wind generator. In general, a deflection field generator can be located proximate to the path of the flow of ionized air. The deflection field generator is configured to generate an electromagnetic field, which deflects a least a portion of the flow of ionized air to a different path and may possibly increase local heat transfer.

Here's Apple's background on the invention: "Many modern electronic systems generate a large amount of heat, and a variety of different cooling mechanisms may be used to cool these electronic systems. For personal electronic systems, such as computers and other relatively transportable electronic systems, the cooling devices in use today are primarily mechanically-based devices, such as electric fans and heat sinks. A cooling device that has been proposed for use in such systems is an ionic wind generator, which generates airflow based on the ionization of air molecules.

"A limitation of currently-proposed ionic wind generator cooling systems for such devices (and for other conventional cooling devices as well) is that the generated airflow, from a first electrode toward a second electrode is limited to a linear path which is essentially static, and thus can only cool a specific region of an electronic system; particularly, only the regions that are in, or immediately adjacent, the path of the airflow can be cooled.

"While the size, placement, and relative orientation of the two electrodes can be established to provide a linear path of a desired direction and dimension so as to provide a selected degree of airflow-based cooling in that region; such systems inherently involve compromises in terms of either performance or cooling capability. For example, because of the fixed path, the ionic wind generator cooling systems must be designed to provide airflow of a sufficient dimension, and in a sufficient amount, to meet all foreseeable cooling needs.

"However, as can be seen from the example of a computer system (such as, for example, a laptop computer), there may be substantial differences in the usage of the processors and other heat sources in the computer at different times, and thus a cooling system designed to meet the highest-level cooling needs may be using more power than would be necessary at times of relatively lower level cooling needs. Additionally, some components within the example laptop computer may not always be in substantial use, such as a graphics processor, that exacerbate heat generation.

"Thus, airflow directed to such a component when it is not heavily used, and is thus generating little heat, again is requiring a greater energy budget that would be otherwise required. Thus, the limitations of such currently proposed ionic wind generator cooling systems for many electronic devices are limited relative to the variable cooling needs of many such systems."

The inventors are Jean L. Lee and Richard Lidio Bianco Jr.
