Abstract

In order to improve the durability of components in the vehicle engine room, an experiment to improve the air cooling effect of components by installing a cooling duct using intake air aiming at four components, such as generator, battery, ECU and power steel oil, Respectively, experimental results show that the overall component temperature has been reduced, and the reduced temperature difference is in the order of generator, ECU, power steel oil and battery. In order to improve the temperature difference due to these components, it is necessary to optimize the design through the flow analysis in the duct in the future.

자동차 엔진룸내 부품의 내구성 향상을 위하여 냉각 가능성을 판단하고자 발전기, 배터리, ECU 및 파워스틸 오일 등 4가지 부품을 목표로 흡입공기를 사용한 냉각용 덕트를 설치하여 부품에 대한 공랭효과를 향상시키기 위한 실험을 수행하였다. 실험 결과, 전반적으로 부품 온도가 저감되었으며 감소된 온도 차이는 발전기, ECU, 파워스틸 오일 및 배터리 순으로 크게 나타났다. 이러한 부품에 따른 온도 차이를 개선하기 위해서는 차후에 덕트 내부에 대한 유동해석을 통한 최적화 설계가 필요하다고 판단된다.
