    摘要： A heat exchanger and a method for additively manufacturing the heat exchanger are provided. The heat exchanger includes a plurality of fluid passageways that are formed by additive manufacturing methods which enable the formation of fluid passageways that are smaller in size, that have thinner walls, and that have complex and intricate heat exchanger features that were not possible using prior manufacturing methods. For example, the fluid passageways may be curvilinear and may include heat exchanging fins that are less than 0.01 inches thick and formed at a fin density of more than four heat exchanging fins per centimeter. In addition, the heat exchanging fins may be angled with respect to the walls of the fluid passageways and adjacent fins may be offset relative to each other.

    摘要： A condensation enhancement heat transfer pipe includes an optical pipe section, a fin section, and a transition section connecting the optical pipe section and the fin section. The outer surface of the fin section is provided with a plurality of individual fins, each of the individual fins has an acute shape of zigzag and forms an angle relative to the axial direction, an axial fin channel forms between the two adjacent ones of said individual fins along the axial direction, a peripheral fin channel forms between the two adjacent ones of said individual fins along the peripheral direction, an end, which is distributed along said axial direction, of each of said individual fins includes platforms, the fin side walls are connected with the platform by an arc, and the platforms are parallel to each other along the peripheral direction. The platform on the fin increases the heat transfer area of the sidewall, and the fin and the platform cause liquid film to flow through several turnings so as to reduce the thickness of the condensation liquid film to decrease the heat transfer resistance. The arc connection between the fin sidewall and the platform facilitates condensation liquid flow. Under the surface tension, the liquid film can flow quickly downward, thus the enhancement of the heat transfer property is maximized.
