Abstract

UN SISTEMA DE REFRIGERACION PARA UN MOTOR DE COMBUSTION INTERNA DE UN VEHICULO DE MOTOR QUE COMPRENDE DOS CIRCUITOS DE REFRIGERACION INDEPENDIENTES (2, 3) PARA LA CULATA Y PARA EL BLOQUE DEL MOTOR. EL FLUIDO DE REFRIGERACION QUE FLUYE A TRAVES DE LA CULATA CIRCULA A TRAVES DE UN RADIADOR (4) EN TODAS LAS CONDICIONES DE FUNCIONAMIENTO DEL SISTEMA DE REFRIGERACION. EL FLUIDO DE REFRIGERACION QUE FLUYE A TRAVES DEL BLOQUE DEL MOTOR SE DESVIA EN CAMBIO PARA QUE NO FLUYA A TRAVES DEL RADIADOR Y, CUANDO SALE DEL BLOQUE DEL MOTOR, SE ALIMENTA EN UN CONDUCTO QUE HAY A LA SALIDA DE LA CULATA DE MODO QUE EL BLOQUE DEL MOTOR SE MANTENGA A UNA TEMPERATURA MAYOR QUE LA DE LA CULATA. UNA UNIDAD DE CONTROL ELECTRONICO CONTROLA LA REGULACION DE UNA BOMBA (7) PARA ACTIVAR LA CIRCULACION DEL FLUIDO DE REFRIGERACION Y LA DE UNA VALVULA DE CONTROL DEL FLUJO (8) QUE DESVIA UNA PORCION DEL FLUIDO DE REFRIGERACION PRESENTE EN EL ORIFICIO DE SALIDA DE LA BOMBA HACIA EL BLOQUE DEL MOTOR. LA UNIDAD DE CONTROL ELECTRONICO (11) LLEVA A CABO LAS REGULACIONES ANTEDICHAS COMO UNA FUNCION DE LAS SEÑALES DIRIGIDAS A LA MISMA DESDE UNA PLURALIDAD DE DETECTORES (12-18) QUE INDICAN UN NUMERO DE PARAMETROS DE FUNCIONAMIENTO DEL MOTOR.
