Performance Characteristics of Automobile Cooling Fan according to Gap between Engine Block and Cooling Fan

엔진 블록과 냉각 팬의 간극에 따른 자동차 냉각 팬의 성능 특성 연구

The performance of cooling fan is affected by many peripheral parts, such as radiator, condenser, engine block and etc. Higher power has been requested in more confined automobile engine room. Thus, cooling performance becomes very important to remove the heat generated from the automobile engine more efficiently. In this paper, the performance of cooling fan including effects of engine block is investigated by using a fan tester based on the ASHRAE and the AMCA standards. A flow rate - gap distance curves and a flow rate - engine block constant curves are obtained from this study.
