Additive manufacturing technologies make it possible to manufacture heat exchanger designs that were impossible to make in the past because of the limitations of conventional manufacturing technologies. Newer designs enabled by additive manufacturing are in some regards technically superior and in some cases cheaper and quicker to manufacture than their classical counterparts. In this work we described the classical heat exchanger designs, and some general methods of sizing. We described the most important types of additive manufacturing technologies along with their advantages and limitations in the manufacturing of heat exchangers. In the experimental part of this work we designed two different designs of a heat exchanger with differently shaped channels and performed a pressure drop analysis.
