ITU-T L.1326 (08/2023)

متطلبات وحالات استعمال حلول التبريد بالسوائل والحلول ذات الكفاءة العالية في استهلاك الطاقة لوحدات النطاق القاعدة من الجيل الخامس (5G BBU) بأسلوب شبكات النفاذ الراديوي المركزية (C-RAN)

‏تُستخدم أنظمة التبريد السائل بشكل أساسي لمعالجة كثافة الطاقة الحرارية العالية التي تتجاوز الحدود المادية لطرق تبريد الهواء، لدعم سيناريوهات التطبيق التي يحقق فيها المصنعون مزايا تنافسية‎. ‏ويمكن للتبريد السائل أن يوفر قدرات نقل الحرارة أعلى بكثير من تلك الخاصة بتبريد الهواء، والتطبيقات التي تتعامل مع الكثافة الحرارية العالية في الشبكة الأساسية الحسابية وحوسبة الحافة وكذلك في شبكات النفاذ سوف تتطلب بشكل متزايد دعم تكنولوجيا التبريد السائل‎.‏تحدد التوصية ‎ITU-T L.1326 ‏متطلبات التبريد السائل وحلول كفاءة استخدام الطاقة العالية من أجل وحدات النطاق القاعدة من الجيل الخامس (5G BBU) بأسلوب شبكات النفاذ الراديوي المركزية (C-RAN)، بما في ذلك متطلبات تكنولوجيا الانغماس والتبريد السائل بالرش، والمؤشرات الرئيسية للغمر والسائل بالرش، ومتطلبات السلامة لنظام الانغماس والتبريد السائل، وإجراء الإدارة وطريقة قياس كفاءة استهلاك الطاقة، وحالات استخدام حلول التبريد السائل.‏ويُقترح في هذه التوصية حل كامل للبنية التحتية في وحدات النطاق القاعدة من الجيل الخامس(5G BBU) ‏ يمكن أن يوفر دعماً تقنياً آمناً وفعالاً للتبريد السائل، مما يمكن أن يساعد في تصميم مرافق تبريد سائل كاملة فضلاً عن الإدخال الناجح لحلول التبريد السائل في غرف الاتصالات ومراكز البيانات القائمة لتبريد الهواء.‎
