Abstract
Using numerical simulation combined with orthogonal experiments to analyze the soldering heat transfer process of solar cells, and studying the effect of different process parameters on temperature stability. The orthogonal experiments design method is used to plan the test plan, and the CFD heat transfer simulation is used to simulate the soldering heat transfer process to obtain the test data. The simulation data are analyzed to obtain the optimal process parameter combination. The results show that when the power of the central lamp is 55 W, the preheating temperature is 150 ℃, the lamp height is 25 mm, the soldering time is 2.2 s, the power of the edge lamp is 70 W, the air flow rate is 0.6 m/s, the temperature stability of the soldering thermal field is highest, and the difference between the simulated temperature and the optimal temperature is 3.5 ℃.
