The main results were obtained as follows:(1) The calculation results of temperature field indicate that, 6139T radiator was brazed using the stage-by-stage heating process, while 6204T radiator with a larger size was brazed using the temperature difference heating process. The uniform temperature distributions in faying faces were all obtained. And the temperatures were in the range of brazing temperature. It is proved that the finite element models established are reasonable.
