Abstract

LA INVENCION SE REFIERE A UNA MAQUINA ELECTRICA REFRIGERADA POR GAS CON UN VENTILADOR (9) AXIAL EN EL EXTREMO DE UN EJE, HABIENDOSE PREVISTO UN ROTOR (1) Y UN CUERPO DE ESTATOR RODEADO POR UNA CARCASA (4) DE MAQUINA EN EL ESPACIO (17) DE CORRIENTE DE SALIDA DEL VENTILADOR (9) AXIAL, CON UN EQUIPO (18) DE CONDUCCION DE GAS DISPUESTO DE FORMA COAXIAL CON RESPECTO AL EJE (2) ROTOR. EN EL ESPACIO DE CORRIENTE EXTERIOR DEL VENTILADOR AXIAL SE GUIA EL GAS DE REFRIGERACION TRANSPORTADO PARA EL ROTOR, EL CUERPO DE ESTATOR Y EL ARROLLAMIENTO DE ESTATOR. ESTE EQUIPO DE CONDUCCION DE GAS ABARCA UNA MULTIPLICIDAD DE ANILLOS (9-25) CONDUCTORES EN FORMA DE CUBIERTA CONICA, DISTANCIADOS UNO DE OTRO Y UNA PARTE (27) ANULAR AL MISMO TIEMPO EN FORMA DE CUBIERTA CONICA, QUE ESTAN UNIDAS ENTRE SI Y CON LA CARCASA (14) DE MAQUINA DE FORMA DIRECTA O INMEDIATA POR MEDIO DE VARILLAS (28,29) QUE DISCURREN DE FORMA ESENCIALMENTE RADIAL. ENTRE CADA UNO DE LOS ANILLOS CONDUCTORES VECINOS DE FORMA RADIAL O DE LAS PARTES (27) DE ANILLO SE CONFIGURA EN LA DIRECCION DE CORRIENTE DE LOS GASES DE REFRIGERACION, UNOS CANALES (K{SUB.1},... K{SUB.8}) ANULARES QUE SE ENSANCHAN DE FORMA CONTINUA. EL EQUIPO (18) DE CONDUCCION DE GAS EFECTUA UNA TRANSFORMACION DE PRESION Y REDUCE LA PERDIDA DE SALIDA EN CONTRA DE LAS SALIDAS DE DISPOSICION DE RUEDA AXIAL HABITUALES HASTA AHORA. DE ESTA FORMA SE AHORRAN ENTRE UN 15 % Y UN 25 % DE LA PERDIDA DE PRESION EN LA MAQUINA Y CON ELLO SE ELEVAN DE FORMA DRASTICA EL EFECTO DE REFRIGERACION.
