Optimized SpiderPIGyorid HX + SpiderPSchwarz HX · 模型 57250
As part of the course “Síntesis de Mecanismos y Máquinas” at the Universidad Nacional de Rosario, we revisited the NASA-GrabCAD Heat Exchanger Challenge using the Post-Conceptual Divergent-Convergent (PCDC) design process. Starting from the original model submitted to the challenge, we analyzed over 100 existing entries, developed a conceptual spectrum of solutions, and explored alternative geometries based on TPMS (Triply Periodic Minimal Surfaces). This process led to the creation of two optimized designs: Optimized SpiderPiGyroid and SpiderPSchwarz, both adapted for additive manufacturing via DMLS with AlSi10Mg. Thermal and structural simulations validated the feasibility of both concepts. The SpiderPiGyroid model achieved a 148% increase in power density, a 52% increase in heat transfer, and improved effectiveness compared to the original entry, while maintaining structural integrity under cryogenic conditions. We gratefully acknowledge the guidance of our professors: Marcelo Valderrey, Ruben Lupi, and Alexis Bregant.
