【摘要】：近年來，隨著筆記本電腦的興起，輕、薄、短、小成為最主要的發(fā)展趨勢，用戶的體驗要求越來越高。其中最重要的三點如下：第一，運算速度快，程序多樣化；第二，散熱性能好，人體與筆記本電腦接觸表面無熱點，且重量要輕。第三，性價比高。針對第一點，由芯片廠商及軟件廠商提供解決方案。針對第二點及第三點，作為散熱工程師，要解決的問題是使散熱器散熱性能好；使散熱器重量減輕，方便攜帶；選取較便宜材料，以便做到性價比高。本文要解決的問題，一個是提高散熱器的散熱能力，另一個是減輕散熱器的重量。因此，對散熱器進行散熱性能優(yōu)化和結(jié)構(gòu)件方面的減重優(yōu)化設(shè)計，對于提高散熱效果和減輕重量具有重大意義。 本文運用FLOEFD及ABAQUS仿真軟件，對筆記本電腦散熱器進行了仿真分析，并做了對照試驗。主要工作內(nèi)容有： 1.使用FLOEFD軟件進行熱仿真分析，選擇適合的翅片間具，厚度，材料，并對仿真結(jié)果進行試驗驗證。 2.運用場協(xié)同理論對翅片進行結(jié)構(gòu)優(yōu)化設(shè)計，包含打凸包，開縫，移動開縫位置，改變凸包形狀，以及凸包分布狀況等，并使用FLOEFD進行仿真與試驗驗證。 3.使用ABAQUS軟件，對于結(jié)構(gòu)件進行受力分析，對于不受力及受力較小部分進行去除材料，試驗驗證仿真結(jié)果。 4.在優(yōu)化后的翅片及結(jié)構(gòu)件的條件下，再次進行散熱效能試驗驗證，確認優(yōu)化后的散熱器散熱性能確實有提高。
[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.
