Abstract

SISTEMA DE GESTION DE LA ENERGIA TERMICA QUE PUEDE UTILIZARSE EN UN DISPOSITIVO COMPACTO DE VISUALIZACION. SE PROPORCIONA UN CONDUCTO (32) DENTRO DEL ALOJAMIENTO DE LA LAMPARA DEL DISPOSITIVO DE VISUALIZACION, Y SE MONTA UNA FUENTE DE LUZ DE ELEVADO VATIAJE (30) DENTRO DEL CONDUCTO. AL MENOS EN UNA SUPERFICIE INTERIOR DEL CONDUCTO, Y EXTENDIENDOSE EN EL INTERIOR DEL MISMO, SE MONTAN MULTIPLES ALETAS DE REFRIGERACION (33). UN REVESTIMIENTO ABSORBENTE DE LA RADIACION TERMICA, COMO UNA ANODIZACION EN NEGRO, CUBRE EL INTERIOR DEL CONDUCTO Y LAS ALETAS DE REFRIGERACION, Y PERMITE UNA MAYOR ABSORCION SUPERFICIAL DE LA RADIACION TERMICA. UN ORIFICIO SITUADO DENTRO DEL CONDUCTO, QUE ES TRANSPARENTE A LA LUZ VISIBLE, SE UTILIZA PARA DIRIGIR LA LUZ VISIBLE A TRAVES DE UN CONJUNTO DE VISUALIZACION (40). UN FILTRO DE INFRARROJOS (38), QUE PUEDE REFLEJAR O ABSORBER LA RADIACION INFRARROJA, COMO EL DENOMINADO ESPEJO CALIENTE, SE UTILIZA PARA MANTENER LA RADIACION TERMICA DENTRO DEL CONDUCTO, Y, A CONTINUACION, SE UTILIZA UN VENTILADOR (55) PARA HACER PASAR FLUIDO DE REFRIGERACION A TRAVES DEL CONDUCTO, PASANDO EL FLUIDO DE REFRIGERACION SOBRE LAS ALETAS DEL CONDUCTO Y RETIRANDO LA ENERGIA TERMICA DEL DISPOSITIVO DE VISUALIZACION DE MANERA ALTAMENTE EFICIENTE.
