| 摘要: |
| 为降低常规蛇形小通道液冷冷板的热阻，提高其对流换热能力，在流道内引入了一种强化换热结构，设计了扰流蛇形小通道液冷冷板，并利用数值模拟方法对两者进行了比较分析。相比于常规蛇形小通道液冷冷板，新的流道设计能够显著降低冷板的总热阻和进、出口压降，降幅分别可达9.2 |

| Abstract: |
| By introducing reinforced heat transfer structure to enhance the convective heat transfer of the regular serpentine minichannel heat sink,a heat sink with turbulence minichannel is constructed and compared with the regular serpentine minichannel heat sink by numerical simulation.Compared with the regular serpentine minichannel heat sink,this new design is found to significantly reduce both the pressure drop across the heat sink and the total thermal resistance by up to 66.7% and 9.2% respectively,and the average Nusselt number is enhanced by 17.2%.The flow and heat transfer in the cold plate is numerically analyzed in detail,and the heat transfer enhancement effect and mechanism of the turbulence minichannel is studied. |
