【摘要】：近年来，随着笔记本电脑的兴起，轻、薄、短、小成为最主要的发展趋势，用户的体验要求越来越高。其中最重要的三点如下：第一，运算速度快，程序多样化；第二，散热性能好，人体与笔记本电脑接触表面无热点，且重量要轻。第三，性价比高。针对第一点，由芯片厂商及软件厂商提供解决方案。针对第二点及第三点，作为散热工程师，要解决的问题是使散热器散热性能好；使散热器重量减轻，方便携带；选取较便宜材料，以便做到性价比高。本文要解决的问题，一个是提高散热器的散热能力，另一个是减轻散热器的重量。因此，对散热器进行散热性能优化和结构件方面的减重优化设计，对于提高散热效果和减轻重量具有重大意义。 本文运用FLOEFD及ABAQUS仿真软件，对笔记本电脑散热器进行了仿真分析，并做了对照试验。主要工作内容有： 1.使用FLOEFD软件进行热仿真分析，选择适合的翅片间具，厚度，材料，并对仿真结果进行试验验证。 2.运用场协同理论对翅片进行结构优化设计，包含打凸包，开缝，移动开缝位置，改变凸包形状，以及凸包分布状况等，并使用FLOEFD进行仿真与试验验证。 3.使用ABAQUS软件，对于结构件进行受力分析，对于不受力及受力较小部分进行去除材料，试验验证仿真结果。 4.在优化后的翅片及结构件的条件下，再次进行散热效能试验验证，确认优化后的散热器散热性能确实有提高。
[Abstract]:In recent years, with the rise of notebook computers, light, thin, short, small become the most important development trend, user experience requirements are higher and higher. The most important three points are as follows: first, the operation is fast and the program is diversified; second, the heat dissipation performance is good, the human body has no hot spots in contact with the notebook computer, and the weight should be light. Third, high cost-performance ratio. For the first point, chip manufacturers and software manufacturers to provide solutions. In view of the second and third points, as a radiator engineer, the problem to be solved is to make the radiator have good radiator performance; to reduce the weight of the radiator and make it easy to carry; and to select cheaper materials in order to achieve high performance-to-price ratio. The problem to be solved in this paper is to improve the radiator's heat transfer capacity and to reduce the weight of the radiator. Therefore, it is of great significance to optimize the heat dissipation performance of radiators and the weight loss optimization of structural parts to improve the heat dissipation effect and reduce the weight. In this paper, using FLOEFD and Abaqus simulation software, the radiator of notebook computer is simulated and analyzed, and the control experiment is done. The main contents of work are: 1. The software FLOEFD is used for thermal simulation analysis. The suitable finned interfin, thickness and material are selected, and the simulation results are tested and verified. 2. The optimization design of finned fin is carried out by using field synergy theory, which includes convex hull, slit, moving slot position, changing the shape of convex hull and the distribution of convex hull, etc. The simulation and experimental results are carried out with FLOEFD. 3. Abaqus software is used to analyze the force of the structural parts, and the material is removed for the unloaded and small parts of the structure. The simulation results are verified by the experiments. 4. Under the condition of the optimized fin and structural parts, the heat dissipation efficiency test was carried out again, and it was confirmed that the heat dissipation performance of the optimized radiator was improved.
