Definitions

  • the invention is based on a method of manufacture a heat exchanger according to the preamble of the main claim.
  • the fins with the water pipes are soldered, taking it to minimize the soldering gap is also known, the tubes after joining of the slats by sliding one rotating driven tool to expand.
  • the solder joint ensures perfect heat transfer from the slats on the pipes, which also ensures adequate cooling of the Slats through the flowing water and the tight fit of the fins on the pipes over the life of the Heat exchanger is guaranteed.
  • primary heat exchangers have high combustion gas temperatures of, for example, 1300 ° C and therefore exposed to this on adequate cooling of the slats in particular to pay attention to, you have so far a soldered version of the Primary heat exchangers considered essential.
  • the inventive method for producing a Heat exchanger according to the features of claim 1 allows a purely mechanical and because of the elimination of Soldering work also shortened assembly of a Heat exchanger for use in High temperature range is determined.
  • each tube is separated by one pushed through, preferably driven in rotation Tool expanded, the excess of which is not expanded inner diameter of the pipe in coordination with the material and the wall thickness of the pipe is dimensioned so that on both sides of the slat feet or Lamella collar form beads on the outer circumference of the tube.
  • the Bumps lie on the slat feet or slat edges firmly, which causes the heat transfer from the fins to the Tube is additionally reinforced.
  • the beads also increase the Strength of the slat seat and prevent the Axially move fins away when expanding the pipe. By the high working pressure also causes the inner wall to roll of the pipe, which also causes the boiling noise behavior of the Heat exchanger is improved.
  • Figure 1 is shown to scale and enlarged a partial longitudinal section through a tube Primary heat exchanger with fins in front of the Expanding the pipe by the tool shown, and Figure 2 shows the same pipe section after expansion.
  • a working in the high temperature range of approx. 1300 ° C Has primary heat exchanger of a gas-fired water heater a number of tubes 10 lying parallel next to one another, which enforce a package of slats 12 which between column 14 for the passage of the combustion gases limit.
  • Each lamella 12 has its through opening or at its foot region 16 a collar 17 which the tube 10th encloses. In the initial state, the inside diameter of the Collar 17 so on the outside diameter of the still smooth Tube 10 matched that the parts without a gap let them fit together.
  • the tubes 10 and the fins 12 are preferably made of copper.
  • each Tube expanded by a tool 18 that passes through the tube is pushed through and is driven in rotation.
  • the tool 18 has a working head (calotte) 20 which is a has cylindrical core part 22, which on its circumference with four chamfered 90 ° on the side Print bars 24 is populated.
  • the work surfaces 26 each two radially opposite pressure bars 24 are in the Distance D from each other, which is slightly larger than that Inner diameter d of the undeformed tube 10 is dimensioned. The excess is in coordination with the wall thickness s of the Tube 10 and its material selected so that the Widen the pipe material firmly to the foot areas 16 or Collar 17 of the fins 12 presses and there radially material displaced to the outside on both sides of this Bulges areas to beads 28.
  • the tubes 10 made of copper have one Inner diameter d of 19 mm, a wall thickness s of 1 mm and the working head 20 has an oversize D-d of 0.3 mm.
  • the beads 12 make the lamellae 12 particularly firm and form-fitting with the tubes 10 in the axial direction connected.
  • the interfaces between the fins 12 and the tubes 10 enlarged so that also results in a particularly good heat transfer.
  • To the Inner walls of the tubes 10 are located at the locations of the beads 28 the pipe material is squeezed outwards, resulting in there annular bulges 30 result. That leads to one undulating formation of the inner wall surfaces, whereby the Boiling noise behavior of the primary heat exchanger improved becomes.
