| 为提高细通道热沉的传热性能，设计了一种内置双倾斜肋片的细通道热沉。通过数值模拟的方法对双倾斜肋片细通道的传热特性、流动特性以
及综合性能进行研究。分析了在一定雷诺数范围内细通道的摩擦阻力因数、努塞尔数、综合性能评估值以及总热阻的变化情况。结果表明：在雷诺数较低时肋片
长度为1.5 mm的通道综合传热性能最佳，在雷诺数较高时肋片长度为1.0 mm的通道综合传热性能最佳。综上可知加入双倾斜肋片的细通道可以增加传热，并降低
总热阻从而有效地提高传热性能。 |

| In order to improve the heat transfer performance of the mini channel heat sink, a mini channel heat sink with double inclined ribs was designed.
The numerical simulation method was used to study the heat transfer characteristics, flow characteristics and comprehensive properties of the mini channel of double inclined fins. The
friction resistance factor, Nusselt number, comprehensive performance evaluation value and total thermal resistance of the mini channel in a certain Reynolds number range were analyzed.
The results show that when the Reynolds number is low, the overall heat transfer performance of the channel with a rib length of 1.5 mm is the best. When the Reynolds number is high, the
channel with a 1.0 mm rib length has the best overall heat transfer performance. In summary, it can be seen that the addition of the mini channel of the double inclined fins can increase the
heat transfer and reduce the total thermal resistance to effectively improve the heat transfer performance. |
