Performance analyses of engine radiator system with capaeity 1000 cc

摘要

A radiator is a significant component of a vehicle engine that is used as a cooling system, specifically a radiator of a car engine that serves to cool the water that has absorbed heat from the engine and then transferred to the air that flowed by the radiator fan. The purpose of this study is to analyze the performance of a heat exchanger of the radiator of the engine 1000 cc. Based on the result of the analysis, it was concluded that the largest total of the heat transfer coefficient occurred at the air flow rate of 125.8x10-3 m~3/s, the air (cold) Uc = 71,48 W/m~2K, and the waterside (heat) Uh = 353,32 W/nrK. The optimum air flow rate occurs at 125.8x10-3 m~3/s. Addition, the total heat transfer coefficient is quite significant, and the effectiveness obtained is 69%. Under all circumstances, the experimental temperature of the radiator outlet air is lower ± 3°C than theoretically, while the temperature of the outlet ah through the radiator lower ± 12°C.
