中文摘要：

设计三种不同流道结构的水冷型热管散热器的水冷板,利用有限元分析软件Fluent,采用基于压力的分离算法和标准K-ε湍流模型对水冷板的温度分布、流动压力损失等方面进行模拟比较。模拟结果表明：采用串并联的槽道结构比单纯的串联结构槽道,具有更好的传热效果以及阻力特性。最后选用流体的压力损失最小直流道串并联结构作为水冷板结构进行试验研究,在水流量0.75L/min时,满负载运行CPU温度稳定在50℃,进出水温差稳定在4.7℃,试验测试和数值模拟数据基本吻合,验证了数值模拟方法的合理性以及水冷型热管散热器在服务器散热应用的可行性。

英文摘要：

Three different flow channel structures of cooling plate on the water-cooling heat pipe radiator are designed. The temperature distribution and the flow pressure loss of the cooling plate are analyzed using the finite element software Fluent,in which the separate algorithm of pressure and the standard K-ε turbulence model are applied. The simulation results indicate that the series-parallel channel structure has better heat transfer performance and resistance characteristics than the series channel structure. The series-parallel channel structure with the least pressure loss is employed to conduct experiment.When the water flow volume is 0.75L/min,the temperature of the CPU working under the full load is stabilized at 50℃,while the temperature difference between the inlet and outlet is stabilized at 4.7℃. The experimental results are in relatively good agreement with the numerical simulation results,which verifies the rationality of the numerical simulation method and the feasibility of the heat transfer application of the water-cooling heat pipe radiator for the servers.
