摘　　要：随着我国双碳目标的提出,对现有能源技术进行节能提效具有重要的意义。为了提高热端部件散热性能,设计了基于液态金属耦合水冷回路的新型双回路散热系统,建立了双回流散热数理模型,数值研究了不同肋片形状对系统散热的影响。结果表明,肋片冷却结构能够有效改变散热系统的换热系数、流动阻力及系统功耗;其中弧形肋片形状的入口流阻较小,系统功耗最小,圆柱形结构次之,矩形肋片换热效果最差。With the proposal of China's dual carbon goals,energy conservation and emission reduction have reached unprecedented heights.In order to improve the heat dissipation performance of hot end components,this paper designs a new dual loop heat dissipation system based on liquid metal coupled water-cooling circuit,establishes a dual reflux heat dissipation mathematical model,and numerically studies the influence of different rib shapes on system heat dissipation.The results show that the rib cooling structure can effectively change the heat transfer coefficient,flow resistance,and system power consumption of the heat dissipation system.Among them,the inlet flow resistance of the curved rib shape is smaller,the system power consumption is the smallest,followed by the cylindrical structure,and the heat transfer effect of the rectangular rib is the worst.
