Abstract

A thermal analysis method taking into account energy balance in each elements of heat exchanger was introduced. This method has a merit in predicting the temperature field over the heat exchanger in detail. To verify this method, the results were compared with the published ones. The thermal analysis of the radiator in vehicles was also conducted and the results were compared with experimental ones. It is concluded that this method can be used in thermal analysis with relatively small error. When the velocity profile of inlet air is not uniform, the outlet temperature of cooling water is higher than that of uniform velocity profile.
