Abstract

EN MAQUINAS ELECTRICAS REFRIGERADAS POR GAS CON UN ESTATOR (3) Y UN ROTOR (6), SOBRE EL QUE VA DISPUESTO UN VENTILADOR AXIAL (9), EL GAS DE REFRIGERACION, VISTO EN DIRECCION PERIMETRAL, PENETRA IRREGULARMENTE EN LA CAMARA DEL CABEZAL DE BOBINADO (13). SI SE PREVE, VISTO EN LA DIRECCION DE CIRCULACION DEL GAS DE REFRIGERACION, DELANTE DEL VENTILADOR AXIAL (9) Y COAXIALMENTE RESPECTO A ESTE, UN ELEMENTO DE CONDUCCION DE AIRE (1) DE FORMA ANULAR CON CHAPAS GUIA (17), Y SE REDUCE LA SECCION DE CIRCULACION PARA EL GAS DE REFRIGERACION, QUE ATRAVIESA EL ELEMENTO DE CONDUCCION DE AIRE (1) EN LA DIRECCION PRINCIPAL DE LA CORRIENTE, A UNA PARTE DEL PERIMETRO EXTERIOR DEL ELEMENTO DE CONDUCCION DE AIRE (1) MEDIANTE UNA CUBIERTA (23), EL EFECTO DE REFRIGERACION ES MAS UNIFORME Y SE APROVECHA MEJOR EL VENTILADOR AXIAL (9).
