摘　　要：[目的]提高冷板式冷藏物流车的充冷效率,优化热管式蓄冷板结构参数。[方法]针对热管式蓄冷板,建立数学物理模型,模拟研究载冷剂不同入口流速和热管管径工况下蓄冷板的充冷过程,并与试验结果进行对比。[结果]模拟研究结果与试验结果吻合较好,充冷过程中,蓄冷剂的平均温度误差为0.28℃。当载冷剂入口流速为1 m/s、热管管径为10 mm时,蓄冷板的充冷性能最优,此时蓄冷板完全冻结时间为74 min,阻力损失为1567.4 Pa,充冷效率为1.2×10^(5)mm^(3)/min。[结论]试验优化的热管式蓄冷板结构能有效提高蓄冷板的充冷效率,缩短充冷时间,降低充冷能耗。[Objective]To improve the cold charging efficiency of cold plate type refrigerated logistics vehicles and optimize the structural parameters of heat pipe type cold storage plate.[Methods]A mathematical-physical model was established for heat pipe accumulator plate to simulate and study the cooling process of the plate under different inlet flow rates of refrigerant and heat pipe diameters,and to compare with the experimental results.[Results]The results of the simulation study were in good agreement with the experimental results,and the average temperature error of the accumulator was 0.28℃in the process of cold charging.When the inlet flow rate of the refrigerant was 1 m/s and the diameter of the heat pipe was 10 mm,the cold charging performance of the accumulator plate was optimal,and the complete freezing time of the accumulator plate at this time was 74 min,with the resistance loss of 1567.4 Pa,and the cold charging efficiency was 1.2×10^(5)mm^(3)/min.[Conclusion]The test-optimised heat pipe accumulator plate structure can effectively improve the cold charging efficiency of the accumulator plate,shorten the cold charging time and reduce the energy consumption of cold charging.
