Heat exchange inefficiencies found in round tube plate fin heat exchangers are eliminated in an aluminum heat exchanger that includes first and second headers (), () and at least one flattened tube (), () extending between the headers (), (). A plurality of generally parallel tube runs are defined and each has opposite edges. A plurality of plate fins (), () are arranged in a stack and each has a plurality of open ended slots (), one for each run of the tubes (), (). Each of the tube runs (), () is nested within corresponding slots () and the fins (), () with one of the edges () of the tube runs extending outwardly of the corresponding fin (). The assembly is brazed together.

Method of fabricating a heat exchanger

Heat exchanger

An elongate manifold construction ( ) having an longitudinal axis ( ) is provided for use in a heat exchanger ( ) having a plurality of tubes ( ). The manifold construction ( ) includes an elongated tank piece ( ) and an elongated header piece ( ). A plurality of embossed beads ( ) having openings ( ) therein that are engaged by tabs ( ) spaced along the longitudinal axis ( ) to maintain the tank and header pieces ( ) in proper alignment with each other so as to obtain a suitable bond joint therebetween during a bonding operation.
