Abstract
order to improve the cooling effect of lithium-ion battery packs, a bionic leaf-vein channel liquid-cooled plate was proposed. The liquid-cooled plate was numerically simulated using ANSYS FLUENT. The results show that at different Reynolds numbers, the pressure drop of the bionic leaf-vein channel is always smaller than that of the serpentine channel, and the local pressure drop of the bionic leaf-vein channel is 88.43% lower than that of the serpentine channel. The pressure drop of the bionic leaf-vein channel increases gradually with the increase of the branching angle, the branching angle increases from 35?to 45?, and the pressure drop increases by 212.27 Pa. The Reynolds number increases from 500 to 7500, and the maximum temperature of the lithium-ion battery pack reduces by 3.74 K, and the maximum temperature difference reduces by 2.25K.
