Influence of Electrohydrodynamic Flows on Intensification of the Heat- and Mass Transfer Processes. Part III. Electroconvection and Electrohydrodynamic Pumps in Cooling and Thermostating Systems

The efficiency of the electrohydrodynamic (EHD) cooling and thermostating systems electronic electrical devices is investigated. A design electroconvective an X-ray generator proposed, effectiveness which confirmed on laboratory models full-scale samples. anode temperature was reduced by a factor two, duration emitter operation increased, reliability device improved. Various methods high-voltage transformer are presented allowing to increase specific power, reduce weigh, size parameters, coolant, augment resource. Studies have been conducted establish possibility heat-emitting element (block) EHD when both external internal conditions change. thermostat with automatic thermal stabilization system has developed tested (the maintained accuracy ± 0.05 °С). frame liquid circuit designed, allows significantly longitudinal differences its deformation. high shown example block light-emitting diodes, small elements components equipment, use electrodes – wires perforated insulating coating flat surfaces; sevenfold in heat transfer coefficient achieved.
