Shell and tube heat exchangers were widely used for their reliabilities and adjust abilities in many industry fields, but it was difficult to design. An optimum model for shell and tube heat exchanger with an objective function of the minimum fee per year was established, and the factors influencing the model were analyzed. The model was realized by the optimum algorithm based on LINGO model linguistic. It was quick of LINGO to carry out the orders and it was easy to be programmed and understood. An experiment showed that LINGO obtained results as reliable as other methods exist. It was feasible to apply LINGO to the optimum design for the shell and tube heat exchangers.
