查询词典 overheating

The results show that the undissolved silicon particles in the melt become the cores of primary silicon precipitated in solidification and there is a close relationship between the shape of primary silicon and undissolved silicon particles. The growth of silicon follows not only the twin plane re-entrant edge mechanism, but also layer mechanism as well. Meanwhile, the shape of primary silicon also relies on kinetic surroundings, such as the transmitting of solute. At higher overheating temperature, the shape of primary silicon becomes the star-shape and tree-shape.

结果表明：重熔过程中熔体中未溶解的硅相粒子，在凝固过程中可成为初生硅生长核心，并且未熔颗粒与初生硅形状之间存在明显对应关系；初生硅的生长机制不是惟一的，既可以以孪晶凹角机制生长，还可以以层状机制生长，初生硅最终形状还要取决于溶质传输等动力学环境；随着熔体过热温度的升高，凝固组织中初生硅形状由多边形向星形及树枝状转变。

In this paper, a thermal simulation model of a LED driver was established. The thermal field and thermal stress analysis of the driver was done by using the software EFD Pro 8.2, and the temperature rise from various parts and the temperature field distribution of the PCB were obtained. By analyzing the reasons leading to overheating and unideal heat distribution, corresponding thermal simulation using an improved model was carried out. Finally, the comparison and analysis of experimental measurement results and simulation results were given.

本文基于计算流体力学中的有限体积法，建立了该变换器的热仿真模型，利用EFD Pro 8.2软件，对驱动电源内部进行了热场及热应力分析，得到了各部分的温升情况和整个电源温度场的分布情况，分析导致PCB局部过热的原因，然后针对热仿真得出的不理想的热分布情况提出了改进的方法，进行了模型改进，对PCB板上的各部分进行合理的重新布局，并再次进行了热仿真，最终得到了较为理想的结果，最后给出了实验测量结果与仿真结果的对比及分析。
