Low temperature cooling provides excellent operating conditions for some conventional and superconducting electronics applications. The cooling requirements for these applications include moderate to low power levels (down to fraction of Watts) and very strict spatial and temporal temperature variation (in the order of 0.1K or less). In this paper, experimental and modeling results of a liquid nitrogen cooling system, using an EHD meso pump are presented. The pumping mechanism uses the EHD ion-drag technique. The experimental set-up, procedures and results are presented, followed by a pumping curve obtained by numerical modeling.
