Abstract: Based on the working process of the liquid cooling charging module, the heating principle of the charging module was analyzed. The key components of the liquid cooling charging pile, such as the circulation pump, the pipeline, the radiator and the cold plate were designed through the theoretical calculation system. The structural temperature field of the cooling cold plate was analyzed by simulation, and the structural optimization design of the cold plate of the liquid cooling charging module was carried out. Combined with the application scenarios and condition constraints of the charging pile, the cooling medium of 56% ethylene glycol aqueous solution was selected as the liquid phase, and 3% graphene powder was added as the solid phase. The results show that compared with the existing liquid cooling modules in the market, the heat dissipation efficiency of the optimized liquid cooling module increases by about 20%. Research on the liquid-solid two-phase flow heat dissipation system of the charging equipment, and using the cooling medium circulation and heat dissipation device to heat the charging equipment are conducive to improving the reliability and service life of the equipment.
Keywords: liquid-solid two-phase flow； liquid cooling cooling system; simulation analysis; optimization of cold plate structure
