Development of Thermal Calculation System for Heat Exchanger Based on VB

The method of thermal calculation in the tubular heat exchanger design was introduced,based on Visual Basic(VB) technique.The complex thermal calculation can be completed in the friendly calculating system with the help of the menu customization technique and the dialogue box technique.The related data are stored in dimension style and read by the program when calculating,making the calculation more efficient.The method of thermal calculation in the heat exchanger design based on Visual Basic (VB) technique was illustrated by an engineering example.It has proved that the method can figure out various parameters and analyze their effects on heat exchanger quickly and accurately.It has certain guiding meaning to the development of other process calculation in the heat exchanger or other fields.
