摘　　要：为满足电池热管理系统紧凑设计的需求,引入基于液体的微流道冷板。采用三维数值方法,在恒定的流道体积下研究了直形、蜂窝、空腔、鱼骨、蛇形和蛛网6种不同的微流道设计中液体冷却剂的层流流动特性,分别从压降、温度变化、平均温度、均匀系数等方面来评价冷却能力。结果表明,蛇形和蜂窝流道可显著改善温度均匀性,而空腔流道则保持较低的压降和泵送功率。To meet the demand for compact design in thermal management systems of batteries,a liquid-based microchannel cooling plate was introduced.A three-dimensional numerical simulation approach was adopted,and the laminar flow characteristics of liquid coolants under constant channel volume were investigated in six different microchannel designs:straight,honeycomb,cavity,fishbone,serpentine,and spiderweb.The cooling performance was evaluated in terms of pressure drop,temperature variation,average temperature,and uniformity coefficient.The experimental results show that serpentine and honeycomb flow channels significantly enhance temperature uniformity,whereas the cavity flow channel maintains lower pressure drop and pumping power.
