엔진 냉각 시스템 유로 개선의 최적화를 위한 실험적 연구

A cooling system is related to engine performance and durability. It is very important to cabin heating for driver as well as engine cooling. A cooling system can be optimized by efficiency improvement of water pump, modification of coolant route and thermal analysis. In this study, the simple change of coolant routes influenced to cooling performance of the engine inside. A cool ing system was evaluated by pressure distribution, flow visualization. Therefore, the coolant flow and direction was predictable by pressure distribution and cooling system can be optimized.
