本文提出了一种基于可移动构件法-密度法拓扑优化的锂离子电池包冷却板流道设计。首先,利用二次贝塞尔函数曲线生成的构件来描述流道。其次,以冷却板最小平均温度作为目标函数,设定约束条件为冷却板中的流体体积与流场耗散构建拓扑优化列式,对具有两个入口两个出口的冷却板流道进行拓扑优化设计。之后采用构件法研究了不同出入口位置下冷却板流道的最优设计,并利用密度法对散热能力较优的流道进一步优化,使得流道布局更加合理、边界更加光滑。最终与传统的栅格形流道相比,基于构件法获得的流道设计平均温度降低了6.653K,最高温度降低了23.62K,基于MMC-密度法获得的流道设计的平均温度降低了6.887K,最高温度降低了24.238K。

In this paper, a cooling plate runner design of lithium-ion battery pack based on the topology optimization of the movable member method-density method is proposed. Firstly, the components generated by the quadratic B-spline curve are used to describe the runner. Secondly, taking the minimum average temperature of the cooling plate as the objective function, the constraints are set to construct a topology optimization column formula for the fluid volume and flow field dissipation in the cooling plate, and the topology optimization design of the cooling plate flow channel with two inlets and two outlets is carried out. Then, the component method was used to study the optimal design of the cooling plate runner at different inlet and outlet positions, and the density method was used to further optimize the runner with better heat dissipation capacity, so that the runner layout was more reasonable and the boundary was smoother. Finally, compared with the traditional grid-shaped runner, the average temperature of the runner design obtained based on the component method is reduced by 6.653 K, the maximum temperature is reduced by 23.62 K, the average temperature of the runner design obtained by the MMC-density method is reduced by 6.887 K, and the maximum temperature is reduced by 24.238 K.
