这个I-Corps项目更广泛的影响/商业潜力是开发可以增材制造的拓扑优化的热交换器。通过将拓扑优化扩展到三维共轭传热系统并考虑增材制造约束，该项目将展示这两种技术的相关性和实用性。由于专注于热交换器技术作为示范平台，这项工作也可以提高许多对流相关应用的能源效率，从汽车到航空航天，电力转换，制冷等，这个I-Corps项目将应用拓扑优化来设计新型热交换器，并在优化过程中考虑增材制造约束。在拟议的研究中的关键创新允许基于密度的拓扑优化控制设计相关的物理边界条件。所得到的热交换器可以被增材制造并测试性能以及耐久性，以便表明拓扑优化过程对于这种类型的应用是可接受的，这种类型的应用沿着沿着多个竞争方面（即，热性能、压降、热应力、破裂压力、蠕变等）。这项技术的发展可能会导致新的热交换器，通过探索增材制造打开的大设计空间，比传统的热交换器散发更多的热量。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。

The broader impact/commercial potential of this I-Corps project is the development of topologically-optimized heat exchangers that may be additively manufactured. By extending topology optimization onto three-dimensional conjugate heat transfer systems and by accounting for additive manufacturing constraints, this project will demonstrate the relevance and utility of both technologies. Because of the focus on heat exchanger technology as the demonstration platform, the work also may improve energy efficiency for a host of convection related applications, ranging from automotive to aerospace, power conversion, refrigeration, etc. This I-Corps project will apply topology optimization to design novel heat exchangers and consider additive manufacturing constraints during the optimization process. The key innovation in the proposed research allows density-based topology optimization to control design-dependent physical boundary conditions. The resulting heat exchanger may be additively manufactured and tested both for performance as well as durability in order to show that the topology optimization process is acceptable for this type of application, which is highly constrained along multiple competing aspects (i.e., thermal performance, pressure drop, thermal stress, burst pressure, creep, etc.). This developed technology may lead to new heat exchangers that dissipate more heat than conventional ones by exploring a large design space opened by additive manufacturing.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
