Numerical smulation study on the inserted heat pipe fin heat sink

基于常规插片式散热器的工艺及结构,开发出一种翅片效率更高的插片式热管翅散热器,并用ICEPAK软件对其进行了数值模拟研究。结果表明:在自然对流条件下,插片式热管翅散热器的热源表面中心点温度比插片式散热器低7℃左右,总热阻低0.13℃/W,说明插片式热管翅散热器具有更好的均温性和传热性能;强制对流条件下,在相同的加热功率和相同的风速下,插片式热管翅散热器热源表面中心点温度和散热器总热阻均明显低于插片式散热器,说明热管翅散热器散热效果很好。

Based on the process and structure of the traditional finned heat sink, it develops a novel inserted heat pipe fin heat sink with high fin efficiency, realizes some relevant numerical simulation research with ICEPAK software. The results show that ： in the condition of natural convection, the evaporation center maximum tempera- ture of the inserted heat pipe heat sink is 7℃ lower than that of finned heat sink, the total resistance is O. 13℃/W smaller as well; under the condition of the forced convection, the evaporation center maximum tem- perature and the total resistance of the inserted heat pipe heat sink is obvious lower than those of finned heat sink, from all those numerical simulation ,it is easy to find the advantages of the inserted heat pipe heat sink.
