本文对结构的质量优化、散热优化过程是一系列的前处理－求解－后处理－优化的循环过程。在满足散热空间条件的前提下，以使散热片中的最高温度值达到最小为目的，运用控制变量法对散热片结构进行优化设计。并且在装配时使散热底板和散热片能够更好的接触，以减小热阻。通过这些措施达到提升散热片散热性能的目的。
通过上述方法，本文设计了电源盒结构并实现了提升电源盒散热效果的目的。通过优化后的三维模型建立二维工程图。最后，对全文进行了总结，并对后续的研究工作提出了一些建议。

Abstract According to statistics, 55% of electronic equipment failure were caused by high Temperature. we can see that the main failure form of electronic equipment is overheating damage, therefore effective heat dissipation for electronic equipment is the key to improve the stability of the product .
This thesis is based on structural design of related housing and cooling components of the power box, then SolidWorks and Simulation software are used to make 3D model and expand the study of static stress analysis and thermal analysis to solve the quality optimization and heat dissipation problem of the power box.
The optimization process of these aspects is a circular process of pre-treatment, solving and post treatment. On the premise of satisfying the constraint of cooling space, the maximum temperature of heat sinks is minimized. Control variables method is used to optimize the structural parameters of the cooling sink. And the cooling base plate and heat sink assembly to make better contact in order to reduce the thermal resistance. These measures are taken to enhance the performance of cooling sink .
Through this method, the purpose to enhance the cooling effect of the power supply box and optimized three-dimensional model and the establishment of two-dimensional engineering drawing have been obtained. Finally, the conclusion of this thesis and the advices for future research are given.
