Problems solved by technology

[0003] The use of fans, blowers or other similar mechanically moving devices to provide cooling airflow is known in the prior art; however, such devices generally have a limited operating life and tend to Generate unwanted noise or vibration, consume power, or suffer from other design issues
Additionally, such devices typically impose geometric, form factor, and / or layout constraints on the systems that provide the cooling air flow

Embodiment Construction

[0047] General electrohydraulic (EHD) fluid acceleration

[0048] The fundamentals of electrohydrodynamic (EHD) fluid flow are well known in the art, and in this regard, Jewell-Larsen et al.'s paper entitled "Modeling of corona-induced electrohydrodynamic flow with COMSOL multiphysics" (in Proceedings of the ESA Annual Meeting on Electrostatics2008") (hereinafter referred to as the "Jewell-Larsen Modeling article") provides a useful overview. Likewise, US Patent 6,504,308, issued October 14, 1999 to Krichtafovitch et al., entitled "Electrostatic Fluid Accelerator," describes several electrode and high voltage power supply configurations that may be used in some EHD devices. US Patent 6,504,308, together with Sections "I (Introduction), II (Background), and III (Numerical Modeling)" of the "Jewell-Larsen Modeling article" are hereby incorporated by reference for all teachings thereof.

Abstract

An electronic system is configurable to accommodate either of a mechanical air mover and an EHD air mover within an enclosure. At least one of a plurality of electronic components is selectively configurable to alternately accommodate the mechanical air mover or the EHD air mover within the enclosure. The mechanical fan or EHD is positioned to motivate air flow along a air flow path between inlet and outlet ventilation boundaries of the enclosure. A connector for a respective one of the electronic components allows for selective configuration in an alternate orientation of the respective one of the electronic components to accommodate a difference in geometry between the EHD air mover and the mechanical air mover.

Description

technical field [0001] The present application relates to thermal management and, more particularly, to microscale cooling devices that generate ions and electric fields to drive fluid flow, such as air flow, to dissipate heat as part of a thermal management scheme. Background of the invention [0002] Many devices or systems, whether electronic, optical or mechanical, may include, provide or require forced flow of air or other fluids. In some cases, forced flow is used to cool or moderate heat generated by heat sources within a device or system. In such cases, cooling or thermal moderation may help prevent device overheating, reduce thermal hotspots, provide desired thermal stability to temperature sensitive devices, improve long-term reliability, or provide other benefits. In some cases, forced flow may be the primary function of the device or system. [0003] The use of fans, blowers, or other similar mechanically moving devices to provide cooling air flow is known in t...
