LOCAL IONIZING FAN Russian patent published in 1999 - IPC

FIELD: ventilation of relatively small-volume spaces, for example of several cubic meters. SUBSTANCE: fan includes tubular body with converging tube for air inlet. Needle type electrode is axially arranged in cavity of fan body and it is connected with negative terminal of electric current (15-35)V power source. Grid closes diametrical cross section of inner cavity of fan body, it is flat or spherical one and connected with positive terminal of above mentioned power source. Optimal geometrical relations for ionizing fan are given. Those relations allow to receive maximum supply and long-range stream at rather small energy consumption and minimum dimensions of fan. EFFECT: improved design of fan having no moving parts and creating no acoustic, temperature and vibration disturbances in environment. 3 cl, 2 dwg
