Abstract. The use of Triply Periodic Minimal Surface (TPMS) geometries in heat exchanger design has gained significant interest due to their excellent surface area-to-volume ratio and potential for enhanced heat transfer. Among various TPMS configurations, the gyroid structure has shown promise in maximizing thermal efficiency. This study focuses on the thermal modeling of gyroid-based heat exchangers to evaluate their heat transfer coefficient. Once the optimal design parameters are identified, the heat exchangers are prototyped using additive manufacturing techniques. Mechanical behavior of the fabricated heat exchangers is assessed, specifically focusing on structural integrity under operational stresses, such as pressure resistance.
