Abstract

UNA ESTRUCTURA DE UN ORIFICIO DE ADMISION (10) Y UN CONJUNTO PROPULSOR (20) PARA UN VENTILADOR DE FLUJO CENTRIFUGO. EL ORIFICIO DE ADMISION (10) TIENE UNA SECCION TRANSVERSAL ELIPTICA EN UN PLANO QUE PASA A TRAVES DEL EJE DE ROTACION DEL VENTILADOR. EL PROPULSOR (20) ESTA CUBIERTO Y TAMBIEN TIENE UNA SECCION TRANSVERSAL ELIPTICA SIMILAR. EL PROPULSOR (20) TIENE UN TAMAÑO TAL QUE, CUANDO SE MONTA, LA CUBIERTA QUEDA SUPERPUESTA Y ROTA ALREDEDOR DEL ORIFICIO DE ADMISION FIJO. EN UN ASPECTO PREFERENTE DE LA INVENCION, HAY 13 PALETAS PROPULSORAS (203) SEPARADAS DE FORMA NO UNIFORME ALREDEDOR DE UNA PLACA DE CUBO (202). SE PRESENTA Y REIVINDICA UN TIPO DE SEPARACION ESPECIAL DE LAS PALETAS. LA SUPERFICIE INTERIOR DE LA PLACA DE CUBO (202) ES CURVA EN FORMA ARQUEADA PARA GUIAR LA CORRIENTE DE AIRE A TRAVES DEL VENTILADOR DESDE SU DIRECCION AXIAL DE ENTRADA A SU DIRECCION DE SALIDA RADIAL. EL CONTORNO DE LA PLACA DE CUBO (202) PERMITE QUE EL MOTOR ACCIONADOR DEL VENTILADOR QUEDE PARCIALMENTE EMBUTIDO EN LA PLACA.
