摘　　要：建立翅片蒸发冷凝器局部稳态湍流数学模型,运用ansys/cfx进行数值模拟,直观的表示出有无翅片对于蒸发冷凝器各热力学参数的影响。并通过定性分析,得出加载翅片有助于蒸发式冷凝器提高其换热性能。A steady local turbulent mathmatical model of Evaporative Condenser with fins was established. Based on numerical simulation by using ansys/CFX, it demonstrate intuitively the different of thermodynamics parameters that under the situation of evaporative condenser with fins and without. By means of qualitative analysis, we can reach a conclusion that evaporative condenser with fins can improve the performance of heat exchanging.
