NASA Challenge Heat Exchanger Schwarz P surface core · 模型 57311
The designed heat exchanger is a recuperator-type unit that features a Triply Periodic Minimal Surface (TPMS) lattice structure at its core, replacing conventional tubular elements. This TPMS-based core significantly improves the heat exchanger's thermal efficiency due to its inherently high surface-area-to-volume ratio, enhanced fluid mixing, and reduced pressure drop. The design promotes better flow distribution and structural integrity while maintaining compactness and enabling material savings. The specific TPMS used is the Schwarz Primitive (P) surface, known for its cubic symmetry and complex, interconnected geometry. This surface consists of two interwoven yet non-touching labyrinths that resemble an inflated version of a simple cubic lattice. Its high porosity and surface complexity make it highly effective for heat transfer and mass exchange applications, and also suitable for advanced uses such as biomedical scaffolds. The geometry is well-suited for additive manufacturing, allowing precise fabrication of customized, high-performance thermal systems.
