Abstract
A method of manufacturing a micro-passage heat exchanger includes preparing a substrate of multiple square tubes, configuring multiple layers of the square tubes in a vertical plane, interposing between each layer a braze alloy to form a core, bonding the multiple layers of multiple tubes to form a core mass, forming in alternate tube layers counter flow fluid channels, providing the core mass with sides and manifolds, and brazing the heat exchanger.
