A heat exchanger has a shell baffles, tube supporting means and tubes, in addition to end caps for the shell once formed, to furnish an intergral heat exchanger. The sheet for forming the tubular sheet and baffles are formed from a singular sheet of material. The tube supporting means includes he baffles which have a plurality of openings formed therein receive the tubes. The sheet is laser or die cut to form the integral baffles and rails, for insertion into the outer tubular shell, and in a further embodiment, with its closure end caps, forming the complete heat exchanger. The baffles are formed from a central panel of the sheet material, which provides arcuate openings through the central panel arranged at a median longitudinally of the tubular shell forming the heat exchanger, and thereby directs the flow of fluids to be heated centrally through the heat exchanger and in a direction where the greatest concentration of heat exchanger tubes is located, for providing maximum efficiency in heating of a further fluid passing through the heat exchanger during its operation.
For use in a heat exchanger formed having an outer shell, a plate means integrally formed having a series of aligned tube supporting means therein, provided for supporting a series of tubes within the heat exchanger, said tube supporting means being bent into perpendicularity with respect to the plate means from which they are formed, said tube supporting means also forming baffling for the heat exchanger, and side rails provided along the longitudinal sides of the said plate means, which when bent into perpendicularity, provides means for supporting a series of heat exchange tubes within the heat exchanger, said side rails, tube supporting means, and plate means, all being integrally formed as a single component from a single sheet of metallic material.
