摘要:
吸液芯结构对超薄平板热管的传热性能有很大影响.为对比不同结构吸液芯的超薄平板热管传热性能,研制了4种吸液芯的超薄平板热管并进行传热性能实验.结果发现:120～200目烧结芯超薄平板热管的热阻最低,在稳定工作时蒸发端温度最低,启动时间最短; 在相近孔隙率下,烧结芯热管比丝网芯热管的传热性能好,粉末烧结结构比网状结构更利于改善毛细力和强化沸腾.
Abstract:
The structure of wick has great influence on the heat transfer performance of ultra-thin flat heat pipe.In order to compare the heat transfer performance of ultra-thin flat heat pipe with different wick structure,four kinds of commonly used wick are fabricated and the experiment of heat transfer performance is carried out.The results show that the ultra-thin flat heat pipe with the 120～200 powder sintered wick has the lowest thermal resistance,the lowest evaporation end temperature at stable work and the shortest start-up time.The heat transfer performance of sintered heat pipe is better than that of wire mesh heat pipe under the condition of similar porosity,powder sintering structure is more conducive to improving capillary force and strengthening boiling than mesh structure.
