Definitions

  • the invention relates to a method for manufacturing a heating body of the sheet type of water tubes arranged around a cylindrical combustion chamber for domestic gas boilers, for example condensing.
  • this kind of heating body requires a rather particular technology of materials, assembly and brazing of the tubes on the annular collectors and this because of the large number of tubes and their proximity necessary for a good coefficient of exchange .
  • These tubes 3 in which the fluid to be heated circulates have an elongated section so that the lateral faces of each tube are parallel to the lateral faces of the neighboring tubes in order to provide between them a gap 5 of small thickness intended for the passage of combustion products .
  • brazing temperature less than or equal to 1000 ° C for about 15 minutes to avoid any grain magnification. This choice is also a function of the specific qualities of this solder, its resilience and its flowability. Too little resilient brazing would be fragile and flowing brazing would require too little play and would risk going up between the tubes. In addition, if it flows too little, it risks giving leaky seals.
