摘　　要：针对电子器件热管理中效率低的问题,提出了基于蛇形管相变液冷强化的热电自发式冷却系统,通过数值模拟深入研究了系统的参数特性、时空演化特性以及冷却匹配特性。研究结果表明:系统冷却性能受到蛇形管散热器的几何参数影响,蛇形管散热器的曲率半径、内径增大,系统冷却性能提升,使用水作为工作流体有较好的冷却性能;系统热电组件的工作性能随着时间变化,100s时刻,系统热电组件产生的电功率达到0.26W;系统的冷却特性受到工作流体流速影响较大,其中系统流速为9.63E-17m/s对应的热电组件冷热端温度差比0m/s流速下的系统热电组件冷热端温度差高17.32K,此外,当蛇形管内流速为4.18m/s时,系统的发电功率和水泵消耗功率相等,系统实现了功率匹配。研究将为热电自发式冷却技术的应用提供参考意见。To address the issue of low efficiency in thermal management of electronic devices,a thermoelectric self-cooling system enhanced by serpentine pipe phase change liquid cooling is proposed.Numerical simulations are conducted to investigate the parametric characteristics,spatiotemporal evolution,and cooling matching properties of the system.The results indicate that the geometric parameters of the serpentine pipe heat sink significantly influence the system's cooling performance.Increasing the curvature radius and inner diameter of the serpentine pipe improves the cooling performance of the system.Water,as the working fluid,demonstrates good cooling performance.The operational performance of the thermoelectric components varies with time,and the electrical power output reaches 0.26 W at 100 seconds.The cooling characteristics of the system are strongly affected by the flow rate of the working fluid.At a flow rate of 9.63×10-17 m/s,the temperature difference between the hot and cold ends of the thermoelectric components is 17.32 K higher than that at 0 m/s.Furthermore,when the flow rate in the serpentine tube reaches 4.18 m/s,the generated electrical power equals the power consumed by the pump,achieving power balance.This study will provide references for the application of thermoelectric self-cooling technology.
