    Abstract: The paper introduces characteristics of the intercooler with aluminum radiating fins lists the formulas to calculate the geometry parameters of the radiator and raises a method to calculate equivalent diameter of the channel outsides fins, forms a equation of convection and heat exchanging and flowing resistance, and reveals the processes to design intercooler. The results show that the calculating error of temperature difference is less than 6%, and the calculating error of flow resistance is below 10%. The method can meet the requirement of designing intercooler.
