ABSTRACT:
A heat exchanger has a shell, baffles, tube supporting means, and tubes, in addition to end caps for the shell, formed to furnish an intergral heat exchanger. The tubular shell and baffles are formed from a singular sheet of material. The tube supporting means includes the baffles, which have a plurality of openings formed therein to receive the tubes. The sheet is laser or die cut to form the integral baffles and outer tubular shell, and in a further embodiment, its closure end caps, for integrally forming the 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 central location 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 are located for providing maximum efficiency in heating of a further fluid passing through the heat exchanger during its operation.
