冰箱用旋翅式冷凝器的计算机辅助设计

Computer-aided design method for spiral-fin condenser of refrigerator

本文介绍了冰箱用旋翅式冷凝器的结构特点以及计算机辅助设计在冷凝器设计中的优点,通过比较冰箱常用制冷剂的物性特点,选择R600a作为设计计算的制冷剂,提出了冷凝器的换热四区模型,并建立了冷凝器的数学计算模型以及计算程序流程图,并且通过实验结果与数学模型的计算结果相比较,得出实验结果与计算结果可以较好的吻合,验证了数学模型与计算程序的可靠性。

The paper introduces the structure features of spiral-fin condenser and the advantages of computer-aided design in the design of the condenser. Choose R600 a as the design calculation through the comparison of characteristics of commonly used refrigerator. The four region model of the condenser heat exchanger was raised, and establish the mathematical model and calculation program flowchart, compare with the results of the experimental and the calculation of mathematical model, both can be in good agreement, and verify the reliability of the mathematical model and calculating program.
