摘要
本文从场协同的角度分析工质在蒸发器毛细芯中的流动与传热情况,针对不同的蒸发器肋片结构参数、毛细多孔芯厚度以及不同的热流密度进行了数值分析。结果表明,利用场协同原理,可以解释不同的蒸发器结构参数和热负荷对蒸发器传热效果的影响,从而为优化蒸发器结构,提高CPL效能提供理论依据。
In the present paper, flow and heat transfer processes under different geometrical structures and different heat flux densities in the porous wick of a CPL evaporator have been numerically studied according to field synergy principle. The calculation results indicate that the heat flux density and geometrical structure, such as fin width and wick height, exert great impacts on the heat and mass transfer efficients of the CPL evaporator, which demonstrates that the field synergy principle may be applied to optimize the configuration of the evaporator and consequently to improve the heat transfer efficient of the CPL system.
