Heat dissipation performance simulation of longitudinal flow air-cooling for cylindrical battery pack
摘要
Abstract
In order to improve the energy density of cylindrical battery packs,a compact battery pack is proposed,the heat dissipation effect of longitudinal air-cooling on the battery pack is studied.The volume of the battery pack cooled by longitudinal flow is reduced by 9.62%compared with that by transverse flow.The lumped parameter battery model and the fluid heat transfer model are coupled in the multi-physical field simulation software,the numerical simulation results show that the temperature rise of the battery can be controlled within 15℃with 4 m/s wind speed.With the same discharge rate(2.0 C),the temperature of the battery increases about 1℃with an increase of 10℃of ambient temperature,the maximum temperature increases about 10℃and the maximum temperature difference increases about 4℃with an increase of 1.0 C discharge rate.The longitudinal flow air cooling has a good cooling effect on the cylindrical battery,especially for applications with strict requirements on volume and weight.关键词
