Effects of air inlet and outlet on thermal management of electric vehicle battery pack equipped with fins
To solve the high heat dissipation problem of lithium ion battery, the air-cooled heat dissipation with fins is adopted for the thermal management. Heat dissipation characteristics of two types of air inlets and outlets (single air inlet and outlet, and double air inlet and outlet) and two types of surfaces (smooth and fin structure) were simulated and compared. When the air inlet and outlet are single inlet and single outlet, compared with smooth battery packs, finned construction packs can increase the Nusselt number by 24.9%. When the air inlet and outlet are double inlet and double outlet, compared with smooth battery packs, finned construction packs can increase the Nusselt number by 13.3%. The double-air inlet and outlet battery pack can significantly reduce the average temperature of the battery pack compared with the single-air inlet and outlet battery pack. Compared with the single-inlet and single-outlet solar smooth battery pack, it can increase the Nu by 131.6%, and the comprehensive performance index can reach 1.66.
期刊介绍：
Asia-Pacific Journal of Chemical Engineering is aimed at capturing current developments and initiatives in chemical engineering related and specialised areas.
