摘要
提出了一种平板热管与热沉一体化设计的方法,通过ANSYS Icepak软件和热阻分析法分析了不同条件下的散热结果,并对新的散热形式进行了优化设计。计算结果表明,利用一体化设计的方案可减小接触热阻28.12%以上,避免风速0.15~0.45 m/s,可减小内热阻,获得均匀的温度场。分析表明,新的设计形式可降低热阻,增强散热效果和改善散热均匀性,为生产制造提供重要参考。
A method of integrated design of flat heat pipes and heat sinks was proposed.The heat dissipation results under different conditions were calculated by ANSYS Icepak software and thermal resistance analysis method,and the new heat dissipation form was optimized.The calculation results show that the integrated design scheme can reduce the contact thermal resistance by more than 28.12%and avoid the wind speed in the interval of 0.15 m/s to 0.45 m/s,which can reduce the internal thermal resistance and obtain a uniform temperature field.This shows that the new design form can reduce the thermal resistance,thereby enhancing the heat dissipation effect and improving the heat dissipation uniformity,which also provides an important reference for manufacturing.
