Study on TPMS Air Heat Sink Structure Flow Heat Transfer Characteristics
A direct current chip heat sink with a Triply Periodic Minimal Surface(TPMS)struc-ture as the core was constructed using Computational Fluid Dynamics(CFD)fluid-solid coupling numerical simulation.The temperature field,fluid velocity,and pressure field of five TPMS struc-tures(Diamond,Gyroid,I-WP,Fischer-Koch,and F-RD)with the same conditions and a traditional fin structure with equivalent porosity were compared.A dimensionless local performance evaluation index was established to comprehensively compare the cooling effects of the six structures.The results indicated that TPMS structures exhibited a performance improvement of 16.6％to 50.6％compared to conventional fin structures.Among them,the Fischer-Koch structure demonstrated the most prominent heat dissipation capability,with greater cooling potential in constrained spaces.The internal flow heat transfer advantage of the Fischer-Koch structure was up to 12 times higher than that of the fin structure.
