Triply periodic minimal surface (TPMS) metamaterials show promise for thermal management systems but are challenging to integrate into existing packaging with strict mechanical requirements. Composite TPMS lattices may offer more control over and properties through material geometric tuning. Here, we fabricate copper-plated, 3D-printed triply primitive evaluate their suitability battery systems. We measure the effects of lattice geometry copper thickness on pressure drop, properties, conductivity. The as internal filling structures in a multichannel cold plate exhibited drops under 6.5 kPa at 1 LPM flow rate. Pressure drop decreased when number channels (width plate) was increased. With 0.43% volume loading, than tripled conductivity still retained polymer-like compliance. A higher relative density did not affect caused elastic modulus compressive strength, stiffer cyclic loading response. design demonstrates that structural parameters mechanical, can be decoupled, which used achieve wide range disparate complex multiphysics

The triply periodic minimal surface (TPMS) is a potential candidate for constructing the next-generation heat exchanger (HEX) due to its considerably high specific area and flexible topology. Considering flow rate volume ratio of cold-to-hot fluid domain, this work aims probe matching effect on thermohydraulic features cross-flow HEXs using gyroid TPMS structures. results indicate that owing contiguous intertwined path, structures induce three-dimensional spiral with three typical characteristics (“merge-split,” parallel, circulation) from different perspectives, dominating mixing exchanger. have negligible influence but intensities. Increasing cold-side velocity constant hot-side can remarkably enhance convection transfer cold side an increased pressure drop, while hot influenced negligibly. Finally, total gradually raised reaches stability limited transfer. A slightly higher recommended improving HEXs.

Lattice structures based on Triply Periodic Minimal Surfaces (TPMS) have been extensively studied in the field of heat exchange due to advantages they can offer terms increased area and enhanced convective phenomena, thanks their intricate geometry. Numerous studies conducted fluid motion within these structures, confirming that Computational Fluid Dynamics (CFD) simulations accurately replicate thermo-fluid dynamic behavior. However, such are computationally expensive may be difficult integrate larger models whole system. Traditionally, exchanger design relies transfer coefficient correlations non-dimensional groups, especially when dealing with turbulent flow. This study proposes a single correlation, results series CFD simulations, calculate for various fluids different TPMS topologies geometries. is achieved through careful selection characteristic lengths groups considered. Within an acceptance range ±20%, predictive capability correlation proved valid three distinct topologies: Gyroid, Schwarz-Primitive, Schwarz-Diamond. It applies across porosity 70% 90%, considering unit cell fluids. Furthermore, presents effect viscous heating at high Reynolds numbers compares proposed existing ones.
