Addireen and NUAA Achieve New Breakthroughs in TPMS Heat Exchange Structure Research

Recently, the collaborative research results between Addireen and Nanjing University of Aeronautics and Astronautics (NUAA) in the fields of metal additive manufacturing and advanced thermal management structures were officially published in the International Journal of Thermal Sciences.

The paper focuses on Gyroid-type TPMS (Triply Periodic Minimal Surface) heat exchange structures. Innovatively, the study introduces Voronoi texture structures onto the Gyroid surface and systematically analyzes the synergistic enhancement mechanism of this composite structure regarding flow and heat transfer performance. This research provides new engineering insights for the structural design of high-performance, compact heat exchangers. As an industrial partner, Addireen was fully involved throughout the structural design conceptualization and engineering feasibility studies.

In recent years, TPMS structures have gained widespread attention in aerospace, power electronics, and advanced thermal management due to their high specific surface area, continuous surfaces, and excellent fluid distribution characteristics. Based on the standard Gyroid structure, this study embeds a parametrically controllable Voronoi texture layer on the surface. This achieves precise modulation of near-wall flow and thermal boundary layers without disrupting the original topological continuity.

Nanjing University of Aeronautics and Astronautics possesses profound expertise in the mechanisms of flow and heat transfer in complex structures, while Addireen has long been dedicated to metal additive manufacturing, the design of complex functional structures, and the translation of engineering applications. Through close collaboration, both parties combined cutting-edge theoretical research with actual manufacturing constraints, ensuring that the research results possess realistic manufacturability and application potential.

This achievement not only provides a new design paradigm for the structural optimization of TPMS heat exchangers but also lays the foundation for future application exploration in liquid cold plates, high-power electronics cooling, and aerospace thermal management components. Addireen will continue to deepen its cooperation with universities and research institutions. Centering on the design, manufacturing, and application translation of complex functional structures, we aim to promote the practical implementation of additive manufacturing technology in high-end equipment and advanced thermal management fields.
