【 摘 要 】

This study was conducted to determine the rate of the heat transfer in the radiator. There are two types of hot fluid, namely water and an ethylene glycol-mixed water of 50%. The water entry into the radiator at the temperature of 80°C. The inlet water varied by 0.00000067 m3/s, 0.00013 m3/s, 0.0002 m3/s, and 0.00027 m3/s, and the air release is 1.489 m3/s. The results indicate that the higher the flow of water flowing on the radiator pipe causes a radiator heat transfer rate increase. The best water releases for the radiator test is 0.0002 m3/s. The enhancement of qh increases of 655.26 W or up to 13.06%, qc increases of 402.04 W or 7.57%, Uh increases of 41.3 W/m2K or 11%, Uc increases of 4 W/m2K or 5.67%, and effectivity increases 2.35%.
