Abstract
Thermal management is needed to control battery temperature to keep it in optimal condition. The cooling system used is a wavy channel and double pipe heat exchanger. Calculation of the effectiveness of the double pipe heat exchanger was carried out to determine its performance. In this research, the fluid used was nanofluid with varying concentrations of 0,1%, 0,3% and 0,5%. Variations in flow direction in the double pipe heat exchanger are considered, namely counter flow and parallel flow. The effect of variations in flow rate is taken into consideration, namely 0,3 LPM, 0,6 LPM and 0,9 LPM. Based on the calculation results, variations in flow direction affect the effectiveness of heat transfer in the double pipe heat exchanger. In variations in the opposite flow direction (counter flow), the highest heat transfer effectiveness is in the 0.5% nanofluid variation with a flow rate of 0,9 LPM, which is equal 59,7 %. In variations in the direction of flow in the same direction (parallel flow), the highest heat transfer effectiveness is in the nanofluid variation of 0,5% with a flow rate of 0,9 LPM with a heat transfer effectiveness value of 42,74 %.. Keywords : Double Pipe Heat Exchanger, Counter Flow, Effectiveness, Paralel Flow, Wavy Channel

| Additional Information: | Manajemen termal diperlukan untuk mengontrol suhu baterai agar tetap dalam kondisi optimal. Sistem pendingin yang digunakan adalah wavy channel dan double pipe heat exchanger. Perhitungan efektivitas double pipe heat exchanger dilakukan untuk mengetahui kinerjanya. Dalam penelitian ini, fluida yang digunakan adalah nanofluid dengan variasi konsentrasi 0,1%, 0,3% dan 0,5%. Variasi arah aliran pada double pipe heat exchanger dipertimbangkan, yaitu aliran berlawanan arah (counter flow) dan aliran searah (paralel flow). Pengaruh variasi laju aliran yang dialirkan dipertimbangkan, yaitu 0,3 LPM, 0,6 LPM dan 0,9 LPM. Berdasarkan hasil perhitungan, variasi arah aliran berpengaruh terhadap efektivitas perpindahan panas pada double pipe heat exchanger. Pada variasi arah aliran berlawanan (counter flow) efektivitas perpindahan panas tertinggi adalah pada variasi nanofluid 0,5 % dengan laju aliran 0,9 LPM yaitu sebesar 59,7%. Pada variasi arah aliran searah (paralel flow) efektivitas perpindahan panas tertinggi adalah pada variasi nanofluid 0,5 % dengan laju aliran 0,9 LPM dengan nilai efektivitas perpindahan panas sebesar 42,74 % . Kata kunci : Double Pipe Heat Exchanger, Counter Flow, Efektivitas, Paralel Flow, Wavy Channel | |||||||||
