Lattice structures, which can now be fabricated using metal additive manufacturing techniques, exhibit varying heat transfer performance depending on the configuration of beam-to-beam connections. In prior research, most lattice designs have been based on crystalline or fibrous geometries, with limited consideration given to flow dynamics. In this study, a novel Staggered Lattice Structure (SG) was developed, featuring V-shaped staggered ribs at the base and a three-dimensionally staggered beam arrangement aligned with the flow direction, aimed at enhancing fluid mixing. Experimental results demonstrate that the SG structure achieves approximately double the heat transfer performance compared to the conventional body-centered cubic (BCC) lattice configuration.
