Abstract
A heat exchanger comprising a multiplicity of longitudinally extending flattened tube structures disposed in a longitudinal coextensive array with fin structures bonded in abutting relation between adjacent pairs of tube structures. First and second header assemblies are connected with first and second end portions respectively of each tube structure and provide a fluid inlet for receiving a first fluid for passage through the tube structures during the passage of a second fluid through the fin structures. The first fluid passes from the second header assembly through a fluid outlet. Each header assembly is formed of a series of interconnected header structures, each of which comprises a pair of sheet metal plates formed to provide first marginal edge portions sealingly fixed in abutting relation with the exterior periphery of the associated tube structure end portion and wall portions spaced in a direction perpendicular to the longitudinal direction of extent of the tube structures having aligned openings therein. The remainder of the marginal edge portions of the plates are sealingly fixed in abutting engagement which together with the first marginal edge portions surround the op…
