The traditional design methods of heat exchanger equipment have a long development cycle, many standards, complex design process and difficult quality assurance. With the 3D modeling and assembly software MDT as the development platform, with the help of ActiveX automation interface technology and VBA integrated development environment, the research of 3D digital modeling and assembly simulation technology of heat exchange equipment is carried out, and a new high-efficiency and energy-saving heat exchange equipment assembly subsystem is developed, which can significantly improve design efficiency and quality. The system implementation method is studied and practiced, the system refers to MDT objects by setting object variables, designs and compiles the drop-down menu and graphical user interface, and presets the error handling mechanism by program code, which solves the key problems in system development.
