摘要： Provision of an expansion region (e.g., a flow path with increasing cross-section downstream of the EHD air mover) can provide operational benefits in EHD air mover-based thermal management systems. In contrast, such a design would generally be disfavored for conventional mechanical air mover-based systems. In some cases, an expansion chamber or volume may be provided between the EHD air mover and heat transfer surfaces. In some cases, expansion of the flow cross-section may be provided (at least in part) within the heat transfer surface volume itself. In some cases, leading surfaces of heat transfer surface (e.g., heat sink fins) may be shaped, disposed or otherwise presented to EHD motivated flow to reduce “laminarity” of the impinging air flow so as to reduce thermal transfer boundary layer effects and/or to divert flow outward in the flow channel so as to more evenly distribute ozone molecules over catalytic sites.
