Requisitos y casos de uso de soluciones de refrigeración líquida y de alta eficiencia energética para BBU 5G en modo RAN centralizado |
Los sistemas de refrigeración líquida se utilizan principalmente para procesar una alta densidad de potencia térmica que supera los límites físicos de los métodos de refrigeración por aire, para apoyar escenarios de aplicación en los que los fabricantes están creando ventajas competitivas. La refrigeración líquida puede proporcionar capacidades de transferencia de calor varios órdenes de magnitud superiores a las de la refrigeración por aire, y las aplicaciones que tratan con alta densidad de calor en el núcleo y en la computación de borde, así como en las redes de acceso, requerirán cada vez más el apoyo de la tecnología de refrigeración líquida.En la Recomendación UITT L.1326 se identifican los requisitos de las soluciones de refrigeración líquida y alta eficiencia energética para BBU 5G en modo centralizadoRAN, incluidos los requisitos de la tecnología de refrigeración líquida por inmersión y pulverización, los indicadores clave de la refrigeración líquida por inmersión y pulverización, los requisitos de seguridad del sistema de refrigeración líquida por inmersión y pulverización, el procedimiento de gestión y un método de medición de la eficiencia energética, y los casos de uso de las soluciones de refrigeración líquida.En esta Recomendación, se propone una solución de infraestructura completa en BBU 5G que puede proporcionar un soporte técnico de refrigeración líquida seguro y eficiente, que puede ayudar en el diseño de instalaciones completas de refrigeración líquida, así como en la introducción con éxito de soluciones de refrigeración líquida en salas de telecomunicaciones y centros de datos existentes con refrigeración por aire. |
