Heat exchangers are devices built for efficient heat transfer fiom one fluid to another and widely used in engineering process. The four heat exchangers consist of shell and tube, spiral, concent~ic (double pipe), and plate heat exchangers available in UTHM Laboratory. This paper 1s aim to identify model nonlinear of the four heat exchanger types. To identify this model, need to use mathematical models of dynamic system using measule the input and output signal of the real system. The process identification requires select model structure, parameter estimatio~i and model validation. ARX (autoregressive with exogenous input) model structure is chosen to fitting criterion and parameter estimation determined and the data measured from the real system will be used model validation. The M-File MATLAB program has generated to siniulale this model to analyze the heat exchangers performance and the best model of these heat exchangers is obtained that based on the fitting which more than 50% and was close to 100%.
