Abstract

ESPIRAL CUBIERTA Y DIVIDIDA EN DOS PARTES PARA VENTILADORES CENTRIFUGOS DIFUNDE Y DIRIGE EL AIRE HACIA ARRIBA, DESDE LA CIRCUNFERENCIA DE UN VENTILADOR CENTRIFUGO CURVADO FRONTALMENTE, HASTA UN PLANO DE DESCARGA SITUADO A UN LADO DEL CITADO VENTILADOR. LA ESPIRAL TIENE UNA PRIMERA PARED CURVADA, DE INCREMENTO MONOTONICO, QUE SE EXTIENDE DESDE UN PUNTO DE CORTE, CERCA DE LA CIRCUNFERENCIA DEL ROTOR, EN LA DIRECCION DE ROTACION, HASTA EL PLANO DE DESCARGA. UNA SEGUNDA PARED CURVADA, DE INCREMENTO MONOTONICO, SE EXTIENDE, EN LA DIRECCION OPUESTA, DESDE EL PUNTO DE CORTE HASTA EL PLANO DE DESCARGA. LAS PAREDES CURVADAS, PRIMERA Y SEGUNDA, SON IMAGENES ESPECULARES UNA DE OTRA, TOMADAS EN EL PLANO CORRESPONDIENTE A LA TANGENTE DEL FLUJO DE AIRE, QUE PASA POR EL PUNTO DE CORTE. UNA CUBIERTA CURVADA SOBRE EL VENTILADOR, EN EL PLANO DE SALIDA, IMPIDE QUE EL RUIDO QUE SE PROPAGA EN LINEA RECTA, SE IRRADIE DIRECTAMENTE DESDE EL ROTOR DEL VENTILADOR HASTA EL ESPACIO DE TRABAJO O LA HABITACION.
