Abstract

Lithium-ion batteries are receiving much attention for powering different electrical systems. During charging and discharging, heat generated may cause a fire. Maintaining a low surface temperature is crucial for the safety of the batteries. The uniform temperature distribution is critical to achieve. Flow through the channel has been used for the active cooling of batteries. Air, water and nanofluid are the fluids utilized in the dynamic cooling system. In the present study, we replace the channel configuration with a triply periodic minimal surfaces (TPMS) sheet made of AlSi10Mg with a thickness of 1 cm. The heat generated using 1C and 4C class of batteries is used. The numerical simulation using COMSOL software investigated different types of TPMS thermal performance. A solid gyroid network is the most suitable for such an application compared to a diamond network and I-graph and wrapped package graph (IWP) network for identical porosity. It is found that besides uniform temperature distribution compared to traditional channel configuration, there is an increase of the Nusselt number of 85% compared to the channel configuration. The performance evaluation criteria are increased by 40% compared to the channel configuration. The surface area of the TPMS plays a crucial role in heat extraction. Two parameters that confirmed the performance of the solid gyroid network are the performance evaluation criterion and the perforated ratio. Both indicated that the reliable gyroid network having a porosity of 0.5 is more effective in heat removal for this application.

在存在三周期极小表面结构的情况下冷却锂离子电池
摘要 锂离子电池为不同的电气系统提供动力,因此备受关注。在充放电过程中,产生的热量可能会引起火灾。保持较低的表面温度对电池的安全至关重要。实现均匀的温度分布至关重要。通过通道的流动已被用于电池的主动冷却。空气、水和纳米流体是动态冷却系统中使用的流体。在本研究中,我们用厚度为 1 厘米的 AlSi10Mg 制成的三周期最小表面 (TPMS) 板取代了通道结构。使用 1C 和 4C 级电池产生的热量。使用 COMSOL 软件进行的数值模拟研究了不同类型的 TPMS 热性能。在孔隙率相同的情况下,固体陀螺网络与菱形网络、I 形图和包裹图 (IWP) 网络相比,最适合此类应用。研究发现,与传统的通道结构相比,除了温度分布均匀外,努塞尔特数还比通道结构增加了 85%。与通道结构相比,性能评估标准提高了 40%。TPMS 的表面积对热量提取起着至关重要的作用。证实固体陀螺网络性能的两个参数是性能评估标准和穿孔率。这两个参数都表明,在这种应用中,孔隙率为 0.5 的可靠陀螺网络能更有效地去除热量。
