N2 - Additve Manufacturing (AM) offers the possibility to design and optimise Heat Exchangers (HX) in a completely new way, beyond the conventional types, which are limited by semi-finished products like pipes and plates. This paper starts with a short summary of the limitations of conventional Heat Exchangers along with possible solutions and potentials offered by AM of Heat Exchangers. A special focus is on the use of lattice structures to enhance heat transfer. A thermo-hydraulically optimised Heat Exchanger for AM by Laser Powder Bed Fusion (LPBF) is presented. Before designing the Heat Exchangers, considerations made are shown. This gas cooler was flow-optimised using CFD simulations and it has an internal lattice structure on the gas side. For a reference element of the structure used, the simulations show an enhancement in heat transfer between 187 and 266% compared to a plain tube. Finally, LPBF printed demonstrator Heat Exchangers and geometries are shown.
