内嵌TPMS结构的主动冷却流道优化设计研究OA

In response to the extreme thermal management challenges faced by hypersonic aircraft,this paper proposes an innovative thermal solution.By integrating the concept of Triply Periodic Minimal Surfaces(TPMS),a biomimetic geometric idea,with topologically optimized channels,this paper introduce a novel design strategy for active cooling channels with embedded TPMS structures.On the one hand,the Gyroid-type TPMS structure is selected as the core filler for the channels,leveraging its excellent thermodynamic properties,high specific surface area,and design flexibility to enhance heat transfer efficiency.On the other hand,topological optimization techniques are employed to refine the channel layout,ensuring maximum cooling effectiveness.Through comparative experimental analysis,this study systematically evaluates the heat transfer performance of unfilled channels and active cooling channels with two different TPMS filling schemes.The experimental results demonstrate that the channels with embedded TPMS structures significantly improve heat exchange efficiency,effectively validating the feasibility and superiority of the proposed innovative design in practical applications.This finding not only provides strong technical support for the thermal management of hypersonic aircraft but also opens up new ideas and methods for the design of efficient thermal control systems in the aerospace field in the future.It highlights the vast potential of combining TPMS structures with topological optimization in addressing heat conduction and dissipation issues under extreme conditions.
