Firmansyah Burlian

Abstract


Manajemen Thermal adalah bagian penting dari proses desain kebanyakan perangkat electronik. Manajemen termal penting baik pada tingkat komponen dan tingkat system yang memainkan peran penting dalam perangkat kualitas, efisiensi, dan, di atas segalanya, itsreliability. Salah satu metode manajemen termal pada peralatan elektronik adalah penggunaan water-block pada pendingin CPU. Pada penelitian ini dilakukan analisis perpindahan panas pendingin CPU dengan menggunakan Metode Elemen Hingga. Hasil analsis menunjukkan Water block CPU yang menggunakan sirip lebih panjang memiliki nilai perpindahan kalor yang lebih baik dibandingkan pada Water block CPU yang menggunakan sirip lebih pendek, dengan Perbandingan perhitungan numeris dan analitis selisih temperatur pada permukaan sirip disetiap dimensi didapat antara 0,005 % hingga 0,7 %.

 

Thermal management is an important part of the design process of most electronic devices.Thermal management is important both at the component level and system level plays an important role in device quality, efficiency, and, above all, itsreliability. One method of thermal management in electronic devices is the use of water-cooling block on the CPU. In this study conducted an analysis of heat transfer using CPU cooling Finite element method. Water analysis results showed that using the CPU block is longer fins transfer heat value better than the CPU water block using shorter fins, with a comparison of numerical and analytical calculation of temperature difference on each dimension of the fin surface obtained between 0.005% to 0.7 %.


Keywords
