  • Publication number: 20220129595
    Abstract: A design and optimization method of a porous structure for 3D heat dissipation based on triply periodic minimal surface (TPMS) belongs to the field of computer-aided design. Firstly, a porous structure is established through implicit function presentation of TPMS. Secondly, a heat dissipation problem is converted into a minimization problem of thermal compliance under given constraints according to a steady-state heat conduction equation. Then, parametric functions are directly computed through a global-local interpolation method. Finally, period optimization and wall-thickness optimization are conducted for a modeling problem to obtain an optimized porous shell structure with smooth period and wall-thickness change. The porous structure of the present invention greatly improves the heat dissipation performance, and efficiency and effectiveness of heat conduction.
