摘要

本文提出一种应用于电动汽车直流大功率快充场景下的液冷充电线缆散热系统，以全氟己酮为液冷工质，蛇形微通道换热器为散热器，基于

-NTU法和分布参数法建立液冷充电线缆冷却系统微通道换热器数学计算模型，通过实验进行模型验证，模型计算值与实验结果一致性较好。通过优化换热器两侧流量、换热器结构和布置方式，有效提高换热性能并减小功耗，采用并联28排管布置，枪头处冷却液温度降低1.81~2.49 ℃，充电线缆最高温度降低3.51~6.44 ℃，对液冷充电线缆冷却系统用换热器的设计具有一定的参考价值。

Abstract

This study investigated a liquid-cooled charging-cable cooling system for the high-power DC fast charger of electric vehicles. This system utilized perfluoro as the liquid coolant and a serpentine microchannel heat exchanger as the radiator. A mathematical model of the microchannel heat exchanger of this liquid-cooled charging-cable cooling system was established using the

-NTU and distributed parameter methods. This model was validated through experiments

which demonstrated good consistency between the calculated values and experimental results. By optimizing the flows on both sides of the heat exchanger

along with its structure and configuration

the heat exchange performance was effectively i

mproved while reducing the power consumption. The system employed a parallel arrangement of 28 rows of tubes

which resulted in a temperature reduction of 1.81-2.49 ℃ for the coolant at the gun head and a maximum temperature decrease of 3.51-6.44 ℃ for the charging cable. The results of this study provide valuable insight into the design of the heat exchangers used in liquid-cooled charging-cable cooling systems.
