相变散热器的结构优化设计

Structure optimization design of phase change radiator

针对现有结构形式相变散热器进行有限元仿真和实验,发现现有结构无法满足性能要求,通过研究分析该相变散热器结构与散热性能之间的关系,在尽可能满足对散热器风阻和外形尺寸等前提条件下,提出了通过增加散热相变通道提高散热器性能。此外对优化后采用30相变通道的结构进行了仿真分析和实验验证,证明了优化的结构确实能够显著提高该相变散热器的散热性能,满足目前性能要求,同时验证了风阻、相变通道数量和散热性能的关系,有利于进一步对相变散热器的研究。

Finite element simulation and experiment were carried out for the existing structure type phase change radiator,and it was found that the existing structure can’t meet the performance requirements.It is proposed to improve radiator performance by increasing phase change channels of radiation under the condition of meeting wind resistance and shape and size of radiator as much as possible,which is obtained by studying the relationship between structure and radiation performance of phase change radiator.In addition,the optimized structure is simulated and verified by experiment,which proves that the optimized structure about 30 phase transition channel can significantly improve the radiation performance of the phase change radiator and meet current requirements.At the same time,the relationship between wind resistance,number of phase change channels and radiation performance is verified,which is conducive to the further study of phase change radiator.
