Abstract:
1. A method of using a minimal surface to make a one piece heat exchanger, the method comprising the steps of: generating a stereolithography file from design data; slicing the stereolithography file into two-dimensional patterns; repeating the two-dimensional patterns sequentially; heating a base with an electron beam gun; forming a one piece three-dimensional minimal surface heat exchanger having a zero mean curvature that does not require assembly of separate pieces, by depositing via electron beam deposition a plurality of layers of a material having a high thermal conductivity onto a top surface of the base, and forming a series of separated plates each having a plurality of rows of fins, forming a core interior portion, forming manifolds, and forming interfacing flanges for connecting the heat exchanger to an exterior; and, cooling the one piece heat exchanger with a cooling agent after all of the plurality of layers have been deposited and the one piece heat exchanger has been formed.
