摘　　要：同时满足屏蔽、密封和导热三个指标,是电子设备机箱设计的一大难题。三者之间往往会产生矛盾,尤其是屏蔽和密封、导热和密封之间。解决这些矛盾,并进行优化处理,是电磁屏蔽机箱设计中的关键问题。介绍了某型号雷达屏蔽导热机箱的设计思路,主要针对屏蔽、密封和导热三个指标进行了详细考量,并进行结构设计优化,使其满足各项指标要求。最后通过仿真和具体试验验证了结构设计的合理性,该机箱的设计成功对同类机箱的设计提供了一种有效的解决思路。It is not easy to cope with electromagnetic shielding, sealing and cooling all at once in designing electronic cabinet. Generally, there are some conflicts occurred in the three aspects, especially between the sealing and the cooling, and also between the shielding and the sealing. How to deal with this problem and to optimize structural design becomes a crucial problem in electromagnetic shielding structure design of cabinet. Design considerations for a radar＇s cabinet are described in this paper. Mainly shielding, sealing and cooling are taken into consideration. Some optimizations are applied to structural design for these aspects, so that shielding, sealing and cooling requirements are better met. By simulation and experimentation, structure design rationality is validated. Its successful design could give guidance and be used as instruction for similar capability cabinet.
