Влияние однонаправленной циркуляции на характеристики многовитковой пульсационной тепловой трубы [Articol]

Abstract

The influence of heat flux density and voltage on the electrohydrodynamic (EHD) pump on thermal resistance, as well as on the temperatures of evaporation and condensation zones of a pulsating heat pipe with three and five turns is studied. A one-dimensional model of the EHD pump is considered. In the presence of EHD pumping, only a gradual start-up mode is observed, the temperature of the evaporation zone is lower than in its absence and it can be regulated within small limits. With an increase in the supplied power, the average temperatures of the evaporation and condensation zones increase. A generalization of the dependences of thermal resistance on the supplied thermal power is carried out.
