Abstract AR
سوف نستقصي - في هذه الدراسة - الحلول الحسابية لأداء تبريد القطع و الأجزاء الإلكترونية آخذين بالاعتبار عددها و ترتيبها.
و سوف نستخدم لذلك حاوية مستطيلة تحت تأثير الحمل الحراري الطبيعي و القصري، و مجالا من أرقام رايلي.
و ينتج المصدر الحراري في الحاوية الحمل الحراري الطبيعي و مصدرا خارجيا لدفع الهواء خلال الحاوية لإنتاج الحمل الحراري القصري.
و قد أبانت النتائج أن أرقام رايلي الكبيرة أدت إلى تحسن كبير في الانتقال الحراري ، بينما أدت أرقام رايلي الصغيرة المصحوبة بزيادة عدد المصادر الحرارية في الحاوية إلى تناقص الانتقال الحراري، و بالتالي زيادة درجة الحرارة القصوى، بينما كان لترتيب و عدد المصادر الحرارية أثر على أداء التبريد، بينما أدت أرقام رايلي الكبيرة إلى نتائج معاكسة.
Abstract EN
The objective of this paper is to numerically investigate the cooling performance of electronic devices with an emphasis on the effects of the arrangement and number of electronic components.
The analysis uses a two dimensional rectangular enclosure under combined natural and forced convection flow conditions and considers a range of Rayleigh numbers.
Heat sources in the enclosure generate the natural convection flow and an externally sourced air stream through the enclosure generates the forced convection flow.
The results show that increasing the Rayleigh number significantly improves the enclosure heat transfer process.
At low Rayleigh numbers, placing more heat sources within the enclosure reduces the heat transfer rate from the sources and consequently increases their overall maximum temperature.
The arrangement and number of heat sources have a considerable contribution to the cooling performance.
However, increasing the Rayleigh number reduces this contribution.
