A computer simulation is proposed for a specialized heat exchanger used in the medical field which provides thermal comfort to potentially hypothermic patients whose bodies can provide a very limited amount of body heat. The model describes the thermal performance of the heat exchanger using a one-dimensional finite difference technique and solving a two-point boundary value problem to obtain the solution. It was found that the model predicts the thermal performance of the heat exchanger quantitatively when compared with the experimental data provided. The errors in predicting the difference between infusate inlet and outlet temperatures experimentally and theoretically were within 10% of experimental values and it is concluded that the program can be used for future design purposes.
