摘要： 在非饱和三层模型基础上,从场协同的角度,对工质在CPL蒸发器毛细芯中的流动与传热情况进行了详细分析。对蒸发器的几何结构参数、毛细多孔芯特征参数以及热负荷变化对工质传热传质效果的影响进行了数值模拟。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。

Abstract: The unsaturated heat and mass transfer characteristics in the porous wick of a CPL evaporator under different geometrical structures and heat flux have been numerically studied based on the field synergy principle.The calculation results indicated that the heat flux and geometrical structures,such as fin width and wick height,exerted great influence on the heat transfer of a CPL evaporator.It demonstrates that the field synergy principle can be applied to optimize the configuration of the evaporator and consequently to enhance the heat transfer in a CPL evaporator.
