Abstract

This study applies flat heat pipe to a specific lithium battery model, employing numerical simulations under natural convection to investigate the temperature distribution within the battery when coupled with and without fins on the condensation section of the heat pipe. Additionally, the orthogonal experimental approach is introduced to explore the impact weights of three fin-related factors – fin length, thickness, and spacing – on the battery's thermal dissipation performance, followed by parameter optimization. The findings reveal that the incorporation of fins effectively reduces battery temperature but results in a decrease in temperature uniformity. The influence of the three fin factors on battery temperature difference is ranked as follows: fin length ⪆ fin thickness ⪆ fin spacing. This research provides valuable guidance for the design of heat dissipation structures for battery.
