Abstract

UN VENTILADOR PIEZOELECTRICO ESTA COMPUESTO POR DOS ALETAS FLEXIBLES OSCILANTES EN OPOSICION QUE SON ACCIONADAS EN RESONANCIA POR UN DISPOSITIVO BIMORFO COMPUESTO POR DOS ELEMENTOS FLECTORES PIEZOCERAMICOS. EL VENTILADOR ESTA DISPUESTO DENTRO EL CONDUCTO DE FLUJO DE UN LASER DE GAS CIRCULANTE. EL FUNCIONAMIENTO DEL VENTILADOR PIEZOELECTRICO SIRVE PARA CREAR UN FLUJO DE UN MEDIO GASEOSO LASERICO EN UN SENTIDO DESEADO A TRAVES DEL CONDUCTO DE FLUJO, REPONIENDO DE ESTE MODO EL MEDIO GASEOSO ENTRE UN PAR DE ELECTRODOS DEL LASER. EL VENTILADOR NO TIENE ELEMENTOS SOMETIDOS A DESGASTE, TALES COMO COJINETES, Y NO PRECISA LUBRICANTE DE COJINETES, LO QUEDA COMO RESULTADO LA ELIMINACION DE CONTAMINACION DEL MEDIO GASEOSO LASERICO POR HIDROCARBUROS DEL LUBRICANTE Y POR PARTICULAR DE COJINETES.
