Overview: Heat Exchangers and 3D Printing, Topology Optimization, Lattice Structures, and Aerospace Applications

Heat exchangers are indispensable in various applications. Generally, heat exchangers are used to transfer heat between fluids (usually moving fluids) to eliminate excess heat generated by components during operation. Particularly in aerospace applications, most of the cooling for engines is provided by air-oil heat exchangers located between the engine and the cabin, which can cool … Read more
