Abstract

Penelitian ini bertujuan untuk menganalisa efisiensi heat exchanger dengan penambahan fin pada setiap tube. Untuk mengetahui efisiensi heat exchanger penelitian ini dilakukan dengan pengujian mesin heat exchanger dengan mengambil data yang diperlukan untuk menghitung dengan persamaan untuk mengetahui hasil efisiensi heat exchanger. Heat exchanger ini berbentuk shell and tube, dimana di dalam shell ada delapan pass setiap satu pass ada delapan tube dan setiap satu tube ada penambahan jumlah fin dua, empat dan enam. Aliran fluida yang digunakan pada penelitian heat exchanger menggunakan aliran cross flow, dimana aliran fluida dingin akan dialirkan melewati tube yang ada di dalam shell yang ditiupkan dengan blower juga diatur kecepatan blower untuk mendapatkan laju massa berbeda dan akan terjadi perpindahan panas atau kalor fluida dingin dari fluida panas yang dialirkan di dalam shell. Melalui proses pembakaran LPG maka dihasilkan fluida panas untuk fluida panas. Fluida dingin yang melewati tube akan menerima kalor dari fluida panas akan menuju ke rotary dryer. Setelah dilakukan perhitungan data, didapatkan heat exchanger dengan jumlah fin 2 setiap tube untuk hasil efisiensi sebesar  57.9%, untuk heat exchanger dengan jumlah fin 4 setiap tube hasilnya sebesar 58.5% dan untuk heat exchanger dengan jumlah fin 6 setiap tube hasilnya sebesar 61.4%.

Abstract

The heat load on computer chips during computing performance is the main topic, so a cooling device is needed. Heat sink is one of the tools commonly applied to reduce the heat load during computing performance of computer systems. Various heat sink configurations have been widely developed and studied to obtain designs with the best thermal performance. This research was conducted to investigate the best design on a straight fin heat sink (SFHS) that has the best thermal and hydraulic performance. SFHS with fin thickness variations of 1 mm, 2 mm, and 3 mm are proposed in this study. The numerical method was carried out using the Computational Flui Dynamics program by considering fluid flow velocities of 4 m/s, 6 m/s, 8 m/s and 10 m/s. The numerical results show that the cooling rate of SFHS can be increased by using SFHS with a thickness of 3 mm and a fluid flow velocity of 10 m/s with a maximum Nusselt number value of 59.74. Therefore, it is concluded that the SFHS has prospects for further study and can be applied practically in the field for micro electronic components and computer systems. Keywords: Heat sink, SFHS, Straight fin.

Abstract

Advanced materials are used in thermoelectric generator (TEG) technology to turn heat into electricity using the Seebeck effect, which helps make better use of heat sources. The Seebeck effect is a result of the temperature disparity that exists between the two surfaces of the TEG. The configuration utilized in this investigation comprises several primary components, including the water block, thermoelectric, heat exchanger plate, and heater plate. The water block is positioned on the cold surface side of the thermoelectric to optimize the cooling process, while the heater plate is positioned on the surface side to facilitate the heating process. Initially, we position the heater plate to avoid direct contact between the heated surface side and the material plate. The plates consist of both copper and aluminum elements. This is done to facilitate the identification of the configuration systems, specifically TEG A (copper) and TEG B (aluminum). The research findings indicate that the TEG B configuration system, when subjected to a heating rate, yields superior voltage, current, and power outputs.
