单颗粒印刷线路板热解传热特性模拟研究
Simulation study on heat transfer characteristics of single printed circuit board particle in pyrolysis process
摘要
Abstract
In order to investigate the effects of the specific heat,thermal conductivity and reaction heat on the temperature distribu-tion and temperature variation of a single printed circuit board (PCB) particle during the pyrolysis process,a mathematical model was established and the heat transfer process of the particle was simulated.The results show that the effect of the specific heat on the temperature variation is more obvious on the center part.The biggest temperature deviation is 21％ when considering and ignoring the variation of specific heat with temperature.The anisotropy of the thermal conductivity has a certain impact on the variation of the temperature.The effects of heat conduction iny direction andz direction are different for different parts of the particle.By comparing the experimental and the simulation results,there is only a 9.78％ difference between the two mass losses,which means the mathe-matical model is reasonable.关键词
