열교환기 배치 구조에 따른 냉각 시스템 성능 시뮬레이션

This study has developed a simulation program for an engine cooling system considering the arrangement and configuration of air side heat exchangers such as air-cooled transmission oil cooler, condenser, and radiator. The program may be also used for the system performance analysis according to the configuration of the coolant side heat exchangers such as water-cooled transmission oil cooler, EGR cooler, and heater core. An experiment utilizing environmental wind tunnel has been conducted for the performance of the system according to the arrangement of air side heat exchangers in front of the radiator. An adjustment of the coolant loop can enhance the heat core performance up to 4%.
