Plate heat exchangers represent a kind of highly compact and efficient heat exchange device. As such heat exchangers feature an extremely complicated heat exchange and flow characteristics, there still lacks, to date, a unified formula for calculating their heat transfer and resistance. At present they are designed and calculated mainly by relying on manual work. However, a manual design and calculation process often suffers from both a high complexity and an extreme inaccuracy. With the comprehensive utilization of such a variety of software as Visual Basic, AutoCad and Turbo C, etc the author has on the platform of Windows 95 developed a visualized computer aided design system. Through the use of that system a designer only needs to input some relevant parameters and the system will automatically complete the whole process starting from the design and calculation and ending with the completion of all design drawings. The system has a user friendly interface and can be conveniently used in practical design work.
