某大功率密封功放单元的热分析及优化

Thermal analysis and optimization of the high-power sealed electronic equipment

以某大功率密封功放单元为例,在其结构设计的基础上,运用Icepak软件进行热分析,根据分析结果反复调整风机位置,并调整散热齿的高度为80 mm.高低温环境试验和可靠性烤机试验证实了该设计的可行性.

With a high-power sealed electronic equipment as an example,the software Icepak was used to thermal analysis on the basis of structure design.According to the results of the analysis,the position of the fan was adjusted and the height of cooling tooth was adjusted to 80 mm.The machine was tested with the high-low temperature experiment and long-term stability experiment smoothly.
