| 摘 要： | 本文采用分布参数法对翅片式蒸发器建立了数学模型，通过计算局部换热系数和摩擦压降来简化翅片式蒸发器内复杂的三维流动关系，总结了文献已有的换热系数和摩擦压降的关联式，并添加到模型控制方程中，基于此模型，可对制冷剂在翅片式蒸发器中应用的换热性能进行模拟研究。

| Abstract: | Numerical model of plate - fin- evaporator is developed.Local heat transfer coefficient and friction pressure drop are calculated in order to simplify complex three - dimensional flow in evaporator. Some correlations is summarized and used in control equations. Based on the model, simulation investigation on plate- fin- evaporator can be carried out. |
