Definitions

  • the invention is based on a gas-fired water heater according to the genus of the main claim.
  • a known Water heater of this type (EP A2 0 213 792) is the as Casting trained heat exchanger on the combustion chamber set up as an independent assembly in Sheet metal construction is executed.
  • the arrangement according to the invention with the features of The main claim has the advantage that the casting of the Heat exchanger and the combustion chamber in one operation a die casting tool largely automated in short Cycle time can be manufactured. Connection operations of the heat exchanger with the combustion chamber are also eliminated may be necessary for a sheet metal construction Support elements are not needed because of the casting solution is self-supporting.
  • a production-oriented execution results if that Casting of the heat exchanger at the inputs and outputs of the Water pipes each have a wall plate connecting the water pipes has to form water chambers with wall bridges and with means for fixing the water chambers tight final cover are provided.
  • a combustion chamber cooling effect is achieved if each side wall of the combustion chamber with wall bridges for formation a channel is provided which one of the chambers with a Connection for an external supply or discharge line connects.
  • the pipe passages and those forming the water chambers Recesses between the wall webs of the wall panels are by retractable, side slides of the die casting tool realized.
  • the covers closing the water chambers can be designed as simple cover plates and under Liner of seals on the wall panels or the Wall bars can be screwed on.
  • FIG. 1 shows a longitudinal section through a the fin block of a heat exchanger and one Casting chamber forming casting
  • Figure 2 shows a section through the casting along the line II-II Figure 1
  • Figure 3 a Side view of the casting in the direction of arrow A in Figure 1 seen
  • Figure 4 shows the other side view of the Cast part according to Figure 1.
  • a casting 10 has three in a heat transfer area 12 water pipes 14, 16, 18 arranged in parallel next to one another which are provided with integrally molded ribs 20.
  • the Water pipes 14, 16, 18 are at their entrances and exits connected in one piece by wall plates 22, 24, at those described in more detail below, for Water webs serving wall guides are provided.
  • the Wall panels 22, 24 are over the heat transfer area 12 extended down to where they have side walls 26, 28 form a combustion chamber 30.
  • the side walls 26, 28 are with a rear wall 32 and a front wall 34 of the combustion chamber 30 connected, which in turn until the Heat transfer area 12 pulled up and there to the Ribs 20 are formed.
  • Two wall webs 36, 38 are formed on the wall plate 22, which together with a cover plate, not shown the two water pipes 14, 16 connecting chamber 40, and delimit a further chamber 42 into which the water pipe 18 flows.
  • On the side wall 26 of the combustion chamber 30 are two Wall webs 44, 46 are formed, which are parallel at a distance are arranged to each other and delimit a channel 48. This connects the chamber 42 or the water pipe 18 with a connection 50 for a supply or discharge of the Pipes of heating water flowing through.
  • Threaded holes 52 for screws for fastening the Cover plate are at different locations on the wall plate 22 Threaded holes 52 for screws for fastening the Cover plate provided.
  • Two wall webs 54, 56 are formed on the wall plate 24, which together with a cover plate, not shown the chamber 58, connecting the two water pipes 16, 18 and delimit a further chamber 60 into which the water pipe 14 flows.
  • On the side wall 28 of the combustion chamber 30 are two Wall webs 62, 64 formed parallel to one another at a distance, which delimit a channel 66 which connects the chamber 60 with a Connects connection 68 for a supply or discharge.
  • the Wall plate 24 is also with threaded holes 70 for Screws for attaching the associated cover plate Mistake.
  • the pipe passages and those between the wall bars on the Wall plates 22, 24 and the side walls 26, 28 of the Combustion chamber 30 recesses are formed by retractable slider, which from the sides in the The working area of the die casting tool protrudes.
  • the sliders are easily according to the manufacturing requirements conical, so that the water pipes 14, 16, 18 from the end faces towards the middle slightly have increasing wall thickness.
  • the fins 20 of the water pipes are characterized by a corresponding structure of an upper and realized a lower die casting tool part.
  • the back wall 32 of the combustion chamber 30 and its front wall 34 protrude above a little beyond the ribs 20, where they hold a recording for form a flow protection.
