Abstract

EL VENTILADOR DE FLUJO AXIAL TIENE UNA PLURALIDAD DE PALAS IDENTICAS (13) QUE SE EXTIENDEN DESDE EL EJE CENTRAL (11). EN UNA CONFORMACION MAS ADECUADA, CADA PALA SE ENCUENTRA ALTAMENTE SESGADA, POSEYENDO UN SESGO TRASERO (CON RESPECTO A LA DIRECCION DEL GIRO DEL VENTILADOR) EN LA PARTE DE LA RAIZ (15) DE LA PALA QUE SE ENCUENTRA MAS CERCA DEL EJE, CAMBIANDO HASTA UN SESGO DELANTERO EN LA PARTE (16) DE LA PALA CERCA DE LA PUNTA. LA PALA PUEDE ESTAR RECUBIERTA O NO RECUBIERTA. EN LA CONFORMACION RECUBIERTA, EL VENTILADOR SE USA JUNTO CON UNA ESTRUCTURA CON UN ORIFICIO DE ENTRADA (131). CADA PALA DEL VENTILADOR TIENE UNA LONGITUD DE SU CUERDA GEOMETRICA QUE SE INCREMENTA DESDE LA RAIZ HASTA LA PUNTA, UN ANGULO DE CABECEO QUE DISMINUYE DESDE LA RAIZ HASTA LA PUNTA Y UN ANGULO DE ALABEO QUE DESCIENDE DESDE LA RAIZ HASTA LA PUNTA. EN SU CONFORMACION CUBIERTA TANTO EL CONTORNO DE LA PARTE DE ENTRADA (126) DE LA CUBIERTA COMO EL CONTORNO DE LA PARTE DE ENTRADA (132) DE LA ESTRUCTURA QUE SOPORTA ELORIFICIO SON SECCIONES CUADRADAS O ELIPSES. EL VENTILADOR REDUCE EL RUIDO Y REQUIERE UN MENOR CONSUMO DE ENERGIA COMPARADO CON LOS VENTILADORES YA EXISTENTES.
