【摘要】 本文探讨了基于AutoCAD二次开发工具ObjectARX的制冷装置部件的计算机辅助设计方法，研究开发了电冰箱CAD系统。该系统完成了对典型制冷装置的换热器部件，如板管式蒸发器、单脊翅片管式蒸发器、箱壁式冷凝器的参数化设计和绘图；分析了绝热型毛细管两相流的物理模型，并建立数学模型，对绝热型毛细管各主要参数对其长度的影响进行了数值模拟和计算分析；基于对电冰箱箱体绝热层厚度的传热分析和计算，完成了整个箱体的参数化设计和绘图工作。整个系统界面友好，操作方便。 此外，本文还介绍了基于Visual Basic6.0的制冷装置自动化动态模拟软件的创建方法和主要功能。更多还原

【Abstract】 This paper mainly describes how to exploit CAD system of the parts ofRefrigerating Plants based on an AutoCAD second developing tool------ObjectARX.Focusing on refrigerators, I develop a refrigerator CAD system. The system implements the parametric design and drawings of many typical kinds of refrigerating parts, e. x. the plate-tube evaporator, the single back-fin evaporator and the box condenser. After analyzing the physical model and setting up the mathematical model according to the two-phase flow of adiabatic capillary tubes, it also numerically simulates and analyzes the different effects of main parameters on the capillary tube length. Based on the heat transfer analysis and counting of thermal insulation layer, the CAD system accomplishes the parametric design and drawings of the refrigerator body. The interface of the whole system is friendly and can be used conveniently.Furthermore, the paper introduces the developing method and the main functions of the dynamic simulation software for refrigerating machines, which is based on Visual Basic 6.0.更多还原
