    Abstract

    Abstrak Penelitian ini bertujuan mengetahui pengaruh komposisi air dan etilen glikol pada coolant terhadap unjuk kerja perpindahan panas dan penurunan tekanan pada radiator tipe corrugated louvered fin with rectangular channel. Penelitian ini menggunakan variasi etilen glikol dan air sebagai coolant radiator dengan komposisi: 100 % air, 80 % air dan 20 % etilen glikol, 60 % air dan 40 % etilen glikol, serta 40 % air dan 60 % etilen glikol. Untuk debit coolant divariasi antara 30 - 45 lpm. Pada penelitian ini temperatur coolant masuk radiator dan kecepatan udara masuk duct dijaga 80 °C dan 3m/s. Hasil penelitian menunjukkan bahwa penambahan etilen glikol dan debit akan meningkatkan laju perpindahan panas dan koefisien perpindahan panas konveksi rata - rata di sisi coolant. Selanjutnya penambahan etilen glikol dan debit akan meningkatkan penurunan tekanan di sisi coolant. Kata kunci: Unjuk kerja perpindahan panas, radiator, coolant. perpustakaan.uns.ac.id digilib.uns.ac.id commit to ABSTRACT The aims of the research are to determine influence of the composition of water and ethylene glycol againts heat transfer performance and pressure drop on radiator having type corrugated louvered fin with rectangular channel. The experiment varied ethylene glycol and water as coolant radiator with composition of 100 % water, 80 % water to 20 % ethylene glycol, 40 % water to 60 % ethylene glycol and 60 % water to 40 % ethylene glycol. The coolant flow rate was varied in the range of 30 - 45 lpm. The inlet coolant temperature and air velocity were set to be 80 °C and 3 m/s, respectively. The results showed that addition volume of ethylene glycol and coolant flow rate will increase average heat transfer coefficient and heat transfer rate of coolant side. Furthermore addition volume of ethylene glycol and coolant flow rate will increase the pressure drop in the coolant side. Keywords: Heat transfer performance, radiator, coolant perpustakaan.uns.ac.id digilib.uns.ac.id commit to
