Definitions

  • ABSTRACT OF .THE DISCLOSURE The method of increasing the rate of heat transfer between fluids in a heat exchanger by electronically increasing the circulation within a fluid and simultaneously removing particulate matter therefrom without mechanically increasing the resistance of the passageways to the flow of fluid therethrough.
  • This invention relates generally to heat exchangers, and particularly to a method by which the heat transfer rate of a recuperative heat exchanger may be substantially increased.
  • FIGURE 1 is a sectional elevation of the heat exchanger according to the invention.
  • FIGURE 2 is a horizontal section of FIGURE 1 as seen from 2-2, and
  • FIGURE 3 is a horizontal section of a modified form of heat exchanger.
  • FIGURE 1 A heat exchanger embodying the present invention is shown in FIGURE 1 wherein a heating fluid admitted to a housing through an inlet 12 is directed through grounded tubes 14 to an outlet 16 and a connected exhaust duct. A fluid to be heated is admitted to the housing through an inlet port 22 where it flows around the tubes 14 to receive heat from the heating fluid inside said tubes before it is exhausted to the outlet port 26 as a heated fluid.
  • the tubes 14 extend axially through the housing 10 between apertured tube sheets 28 and 34 having one or more baflle plates 36 preferably positioned therebetween to effectively increase the dwell period of any fluid passing over the tubes between inlet and outlet ducts.
  • Each tube 14 contains a centrally mounted discharge electrode 38 supported by insulators 40 which electrically isolate the electrodes 38 from the grounded tubes 14.
  • the discharge electrodes 38 are themselves electrically charged by being connected to a suitable source 42 of high voltage direct current, and then discharged across the space which surrounds each electrode to the grounded tubes 14.
  • an electric Wind is produced transversely with respect to inlet and outlet ports so as to increase the turbulence of the fluid inside the tubes and to preclude conditions of laminar flow. Inasmuch as laminar flow conditions are obviated without the necessity of placing extended surface means in the fluid stream, there is an increase of heat transfer without a corresponding increase in pressure drop of the fluid.
  • FIGURE 3 shows a modified form of the invention wherein the tubes of the design illustrated in FIGURES 1 and 2 have been replaced by plates 44 spaced apart according to a predetermined plan to provide alternate inter-plate passageways 14 and 48 for the heating fluid and the fluid to be heated.
  • Ionic discharge electrodes 38 may be subsequently positioned in the passageways for one or both of the fluids in accordance with the foregoing disclosure to increase the rate of heat transfer of the several fluids.
