HEAT EXCHANGER WITH INDIVIDUAL TWINPLATE HEADERS Abstract of the Disclosure A heat exchanger (10) comprising a multiplicity of longitudinally extending flattened tube structures (12) disposed in a longitudinally coextensive array with fin structures (20) bonded in abutting relation between adjacent pairs of tube structures. First and second header assemblies (22) 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 (24) formed to provide first marginal edge portions (30) sealingly fixed in abutting relation with the exterior periphery of the associated tube structure end portion and wall portions (32) spaced in a direction perpendicular to the longitudinal direction of extent of the tube struc- tures having aligned openings (34 and 40) 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 openings and define with the spaced portions an enclosed first fluid containing volume communicating the interior of the associated tube structure end portion with the openings. Each spaced portion of each pair of sheet metal plates is sealingly fixed to a spaced portion of an adjacent pair of sheet metal plates along peripheries defining the openings therein.
