A heat exchanger for transferring heat from a hot gas to a fluid includes two or more corrugated fin structures defining a plurality of hot gas flow channels extending in a generally linear first direction. A fluid conduit includes an outer wall at least partially bonded to at least two of the corrugated fin structures. The fluid conduit defines a plurality of sequentially arranged flow passes for the fluid traveling therethrough. Each of the plurality of flow passes directs the fluid in a direction generally perpendicular to the first direction.

Heat exchanger and method of making the same

A header plate () is provided for receiving the flattened tubes () of a heat exchanger. The header plate () includes a plurality of tube receiving openings (), with each of the openings being surrounded by a flange or collar () that extends from a base wall () of the header plate () towards the heat exchanger core () to surround the exterior cross section of the associated tube (). Each of the flanges () is shaped to conform to the exterior of the associated tube (), and a blend radius R is provided at the interface between the base wall () and the flange (). The blend radius R has a size that increases from a radius Rcentral to the length of a long side wall () of the flange () to a radius Rcentral to the length of a short side wall () of the flange ().

Header plate for use in a 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.
