Abstract: The criteria of convergence of many reported numerical studies of conjugate heat transfer in tube bank fin heat exchangers have not been clearly addressed. In this paper, the criteria are addressed clearly. The results show that when the relative error of any field variable or characteristic number is less than certain value is chosen as convergence criterion, the balance between the heat transferred from and to the fins cannot achieve. This implies that in numerical method using conjugated method, the physical requirement of the studied problem must be enforced in choosing the criteria of convergence.
