基于圆形翅片正交设计排布的双流道液冷板散热性能优化
Research on the Optimization of Heat Dissipation Performance of Dual-Channel Liquid Cooling Plate Based on Orthogonal Design of Circular Fins
摘要
Abstract
To address the issue of excessive temperature in battery cells caused by uneven heat dissipation of liq-uid cooling plates,computational fluid dynamics(CFD)methods are employed to optimize the structure of the liquid cooling plate's flow channels,the arrangement of the find within the channels,and the liquid cooling strategies to enhance the heat dissipation performance of the liquid cooling plate and improve temperature unifor-mity of the battery cells.The flow channel of the liquid cooling plate is transformed from an initial single inlet and outlet structure to a dual inlet and outlet dual-channel structure by increasing the number of inlets and out-lets and changing their positions.Turbulence fins are added within the channels to enhance cooling perfor-mance.Using orthogonal simulation methods,the lateral distance(a),longitudinal distance(b),and height(h)of circular fins in the channel are studied for their impact on the maximum and average temperature of the battery cells,thereby determining the optimal arrangement of the fins.To achieve the same cooling effect as a constant flow liquid cooling strategy while reducing the energy consumption of the liquid cooling plate,a vari-able flow liquid cooling strategy implemented to achieve pressure drop in the channels.Results indicate that compared with the initial structure,the dual inlet liquid cooling plate reduces the maximum temperature of the liquid cooling plate by 0.72℃;the height of the fins has the greatest impact on the heat dissipation of the liquid cooling plate;the optimal parameter combination for orthogonal arrangement is a4b3h3,under which the maxi-mum and average temperatures of the battery cells decrease by 0.33℃and 0.40℃,respectively,compared to when no fins are arranged;the variable flow liquid cooling strategy leads to pressure drops in the channels dur-ing the second and third discharge phases,reduced by 34.79%and 13.19%,respectively.关键词
