The present disclosure relates to an air duct for a battery pack cooling device, and more particularly, to an air duct for a battery pack cooling device for an electric vehicle in which a plurality of cooling flow paths having an effect of more efficiently cooling a battery pack of an electric vehicle are formed in order to properly cool the temperature of the battery module to maintain the performance of a battery in an optimal state. When air, which is a refrigerant, flows through the cooling flow paths to cool the battery module, and the air introduced through an inflow hole of the cooling passage passes through a narrow width portion formed narrowly in a wide width portion, so that the flow velocity passing through the cooling flow path is increased, and the heat transfer efficiency is increased to improve the cooling efficiency.

    개시된 내용은, 배터리팩 냉각장치용 공기덕트에 관한 것으로, 더욱 상세하게는 배터리모듈의 온도를 적절하게 냉각시켜 배터리의 성능을 최적의 상태로 유지할 수 있도록, 전기자동차의 배터리팩을 보다 효율적으로 냉각시키는 효과가 있는 다수의 냉각유로가 형성된 전기자동차용 배터리팩 냉각장치용 공기덕트에 관한 것이다. 냉매인 공기가 냉각유로를 통과하면서 배터리모듈을 냉각시키는데, 냉각유로의 유입공을 통해 유입된 공기가 폭이 넓게 형성된 광폭부에서 폭이 좁게 형성된 협폭부를 지나면서 냉각유로를 통과하는 유속이 증가하게 되어 열전달 효율이 증가되어 냉각효율이 향상된다.
