STUDY ON COOLING OF BIONIC LEAF-VEIN CHANNEL LIQUID-COOLED PLATE FOR LITHIUM-ION BATTERY PACK

ABSTRACT
In 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°-45°, and the pressure drop increases by 212.27 Pa. The Reynolds number increases from 500-7500, and the maximum temperature of the lithium-ion battery pack reduces by 3.74 K, and the maximum temperature difference reduces by 2.25 K.
