Definitions

  • the subject of the invention is a heat exchanger more specifically intended for mixed gas boilers.
  • the invention therefore relates to a heat exchanger using in a finned tube where the primary fluid circulates, a bundle of small rectilinear tubes in series for the circulation of secondary fluid provided with corrugations making it possible to avoid the use of wires or turbulence generating springs.
  • the corrugations carried by two sections of adjacent rectilinear tubes are oriented and positioned with respect to each other so that there is no overlap between the adjacent turns and that the surfaces of exchange are thus increased in order to intensify the convection of the water inside the finned tube.
  • the nesting of neighboring turns is avoided by the fact that the undulations of each section of tube are inclined relative to the longitudinal axis of the tube and that the directions of inclination of these undulations are opposed between two adjacent tubes.
  • the tube 1 on which are fins not shown, constitutes the tube ex-. dull in which the primary fluid of the heating circuit circulates.
  • These small tubes form a serpentine appeared by the secondary fluid (drawing water) entering and leaving the exchanger by the end fittings 4.
  • each small straight tube is in series with a straight tube which is diametrically opposite it.
  • the straight tube sections 2a, 2b, 2c carry external corrugations extending substantially transversely relative to the longitudinal axis of the tubes. These undulations are carried only by the straight parts of the tubes, with the exception of bent sections 3, which are simple tubular bends welded to the straight sections, or which are obtained by bending an area not provided with ripples of uri straight tube. These undulations are also inclined relative to the longitudinal axis. As the axes shown show, the inclinations of two neighboring tube sections 2a, and 2b, or 2b and 2c, etc.
  • substantially identical results are obtained by alternating between adjacent tubes corrugations perpendicular to the longitudinal axis of the tubes and corrugations inclined on this axis, with any direction of inclination.
  • the invention encompasses all variant embodiments in particular as regards the pitch of the corrugations, their inclination, and their spacing.
