Design and Numerical Investigation of High-Performance Heat Exchangers Containing Triply Periodic Minimal Surface Lattice Structures

This research explores the transformative realm of heat exchanger design, focusing on three different lattice types—gyroid, diamond, and SplitP. This study systematically investigates the impact of different cell sizes and wall thicknesses of the lattice structure on the performance of these innovative heat exchangers. The goal is to identify the design parameters of a high-performance heat exchanger with minimal fluid pressure loss but maximum heat transfer. Utilizing advanced computational simulations and modeling techniques, we delve into the intricate details of fluid dynamics within heat exchangers featuring distinct lattice geometries. By systematically adjusting lattice cell size and wall thickness, the research aims to identify the optimal configurations that maximize heat transfer efficiency while ensuring structural integrity. The analysis encompasses detailed examinations of fluid flow patterns, temperature changes, and pressure drops across the different lattice types. These complex heat exchangers were designed for additive manufacturing. The findings promise to guide the development of more efficient and customized heat exchangers, with implications for a wide range of applications where precise thermal management is paramount.
