摘要

为改善锂离子电池热管理系统中相变材料（PCM）因热导率低而导致的热饱和问题，创新地设计了一种环绕电池布置的三周期极小曲面（TPMS）骨架与PCM相结合的复合热管理系统。首先，通过实验测试不同荷电状态下的电池内阻，验证了电池-PCM耦合传热模型的可靠性。随后，以电池最高温度（

）和最大温差（∆

）为关键评价指标，系统比较了纯PCM、传统翅片-PCM以及TPMS-PCM三种方案在3C放电倍率下的热管理性能。结果表明，在相同TPMS体积分数条件下，TPMS-PCM方案对应的电池

Abstract

To address the thermal saturation caused by the low thermal conductivity of phase-cha

nge materials (PCMs) in lithium-ion-battery thermal-management systems (BTMSs)

in this study

we have designed an innovative composite thermal-management system that features a triply periodic minimal surface (TPMS) exoskeleton arranged around the battery and integrated with the PCM. First

we verified the reliability of the coupled heat-transfer model for the battery-PCM through experimental tests of the internal resistance of the battery under different states of charge. Subsequently

using the maximum battery temperature (

max

) and maximum temperature difference (∆

max

) as key evaluation metrics

we compared the thermal-management performance of a pure PCM

a conventional fin-PCM

and a TPMS-PCM configuration systematically at a 3C discharge rate. The results show that

for the same TPMS volume fraction

the

max

of the battery with the TPMS-PCM configuration is only 33.81℃

which is 3.71℃ (2.17℃) lower than that of the pure PCM (fin-PCM) configuration

thus demonstrating its significant cooling advantage. Parametric analysis revealed that increasing the radial lattice density and volume fraction of the TPMS structure can enhance both cooling and temperature uniformity. Among the tested configurations

the P-30-60 structure (30% volume fraction

60° circumferential distribution) exhibited the best overall performance

with

max

=33.74℃ and ∆

max

=3.02℃. To achieve a synergistic balance between thermal performance and structural lightweighting

in this study

we propose a radially graded-density TPMS design (P-VD). This design employs a higher volume fraction near the battery side to enhance heat absorption and a dense thin-walled structure on the outer side to expand the heat-dissipation interface. Compared to the P-30-60 structure

the optimized P-VD structure reduces the volume of the TPMS metal skeleton by 30.4%

while further lowering

max

0.54℃ and ∆

max

by 0.48℃

(∆

max

decreased from 3.02℃ to 2.54C

a reduction of 15.4%). Additionally

the heat absorption (dissipation) area increased by 66.89% (35.78%). The proposed surrounding TPMS-PCM architecture and its graded-density design effectively overcome the trade-off between material use and performance in homogeneous structures. This provides an innovative and feasible design approach and a technical pathway for achieving the multi-objective collaborative optimization of "efficient heat dissipation

excellent temperature uniformity

and lightweight structure" in BTMSs.
