摘要

温度和压降（Δp）是反映液冷电池热管理系统（BTMS）性能的两个关键因素。因此，设计一种冷却性能好、功耗低的液冷结构就显得尤为重要。本文以四叶草的外形为灵感，基于仿生知识，结合正弦函数曲线，提出了一种基于正弦函数曲线设计的仿生四叶草液冷板模型。首先，分析了叶片与进口之间的距离对冷板散热性能的影响。结果表明，当距离为0时，液冷板性能最佳。其次，讨论了不同进出口结构对液冷板综合性能的影响。结果表明，两进四出结构的热工性能最佳，综合性能指标提高20.34%。随后，讨论了叶片间不同连接鳍结构对叶片性能的影响。结果表明，连接翅片结构对冷板热性能的影响最小。最后，对仿生四叶草液冷通道振幅(a)、叶片通道宽度(b)、分支通道宽度(c)、中心通道宽度(e)进行多目标优化。与原始模型相比，优化后的模型平均温度降低了1.32°C(3.25%)，压降降低了18.58 Pa(75.56%)，整体性能提高了89%。

Research on the thermal performance of an innovative bionic four-leaf clover liquid cooling plate based on sine function

Temperature and pressure drop (Δp) are two key factors that reflect the performance of a liquid-cooled battery thermal management system (BTMS). Therefore, it is particularly important to design a liquid-cooled structure with good cooling performance and low power consumption. Inspired by the shape of a four-leaf clover and based on bionic knowledge combined with sine function curves, a novel bionic four-leaf clover liquid cooling plate model designed with sine function curves was proposed in this paper. First, the effect of the distance between the blade and the inlet on the heat dissipation performance of the cold plate was analyzed. Results indicated that when the distance was 0, the liquid cooling plate performed best. Next, the influence of different inlet and outlet configurations on the comprehensive performance of the liquid cooling plate was discussed. Results revealed that the two-inlet, four-outlet configuration provides the best thermal performance, with a 20.34 % improvement in the comprehensive performance index. Subsequently, the influence of different connecting fin structures between the blades was discussed. Results indicated that the connecting fin structures had a minimal impact on the thermal performance of the cold plate. Finally, multi-objective optimization was conducted for the amplitude (a) of the bionic four-leaf clover liquid cooling channel, the width (b) of the blade channel, the width (c) of the branch channels, and the width (e) of the central channel. Compared to the original model, the optimized model exhibited a 1.32 °C (3.25 %) reduction in average temperature, an 18.58 Pa (75.56 %) decrease in pressure drop, and an overall performance enhancement of 89 %.

期刊介绍： The International Journal of Thermal Sciences is a journal devoted to the publication of fundamental studies on the physics of transfer processes in general, with an emphasis on thermal aspects and also applied research on various processes, energy systems and the environment. Articles are published in English and French, and are subject to peer review. The fundamental subjects considered within the scope of the journal are: * Heat and relevant mass transfer at all scales (nano, micro and macro) and in all types of material (heterogeneous, composites, biological,...) and fluid flow * Forced, natural or mixed convection in reactive or non-reactive media * Single or multi–phase fluid flow with or without phase change * Near–and far–field radiative heat transfer * Combined modes of heat transfer in complex systems (for example, plasmas, biological, geological,...) * Multiscale modelling The applied research topics include: * Heat exchangers, heat pipes, cooling processes * Transport phenomena taking place in industrial processes (chemical, food and agricultural, metallurgical, space and aeronautical, automobile industries) * Nano–and micro–technology for energy, space, biosystems and devices * Heat transport analysis in advanced systems * Impact of energy–related processes on environment, and emerging energy systems The study of thermophysical properties of materials and fluids, thermal measurement techniques, inverse methods, and the developments of experimental methods are within the scope of the International Journal of Thermal Sciences which also covers the modelling, and numerical methods applied to thermal transfer.
