Schwarz Primitive Surface-Based Heat Exchangers Adapted for Additive Manufacture

The introduction of additive technologies may require an update in the methods of developing heat exchangers (HE). A variant of the methodology of HE parametric design has been demonstrated on a Schwarz P-surface. A 3D-calculaiton of a row-by-row representative HE model has been used to obtain data for deriving empirical criterial dependences suited for a fast engineering calculation of HE thermohydraulic characteristics. Within the framework of the technological testing and approval of HE manufacture on Schwarz P-surfaces, possibilities have been demonstrated for their scaling and for a reduction in roughness in the course of postprocessing for different materials.
