CIRCULAR CROSSFLOW HEAT EXCHANGER

Abstract:

A heat exchange module, a heat exchanger and a method for additively manufacturing the heat exchanger are provided. The heat exchanger includes a plurality of stacked heat exchange modules defining a flow passageway. Each heat exchange module defining a substantially curved closed geometry defining a central axis that extends along the axial direction. Each heat exchange module includes a first heat exchanging fluid inlet, a first heat exchanging fluid outlet and a plurality of heat exchange tubes fluidly coupling the first heat exchanging fluid inlet and the first heat exchanging fluid outlet. The plurality of heat exchange tubes defining a plurality of first heat exchanging fluid flow passages of equal length and a plurality of second heat exchanging fluid flow passages of equal hydraulic diameter.
