Definitions

  • the invention relates to a gas heat exchanger, in particular for a combustion device, with a helically or spirally wound tube with directly lying pipe windings for formation a space for a heating gas such as a combustion gas.
  • the invention further relates to a tube for Manufacture of such a heat exchanger.
  • the water space of a heat exchanger can consist of one Metal jacket, but also from a screw or spiral Pipe winding exist. With a pipe winding the individual windings lie directly on top of each other. she form a cylindrical space which, at one Incinerator, the combustion chamber and surrounds at least part of the combustion gas exhaust.
  • the pipe winding is made from one Round tube that can be easily screwed or Spiral shape can wrap, and the windings after they have been wound according to a screw or spiral shape are on top of each other and are along a line touch.
  • the enclosed space is therefore exclusive sealed to the outside along this line, and therefore it cannot be completely ruled out that heating gas is out exits the water space.
  • the pipe windings must therefore be provided with an outer jacket.
  • the present invention has an object To provide heat exchangers of the type mentioned at the beginning, in which the heat transfer from the heating gas to the water in the Pipe winding is optimized, and in which the of the Pipe winding surrounding space is largely sealed.
  • the heat exchanger according to the invention is thereby characterized in that the pipe in the area of the heating gas space has a longitudinal rib interrupted by transverse slots.
  • a tube with a longitudinal rib can be easily by extrusion.
  • the longitudinal rib shows in predetermined distances cross slots so that they are in the plane of the longitudinal rib can wrap. Become one with one such a tube provided on a suitable Heated temperature so it can be easily wound will.
  • the transverse slots are preferably from the base V-shaped and directed outwards.
  • the rib therefore does not resist winding. If the The slots are wide enough Flow areas for the heating gases also in the wound Condition still wide enough.
  • the wound single tube of described type can also be one of two spaced Pipes with an intermediate one, with transverse slots provided longitudinal rib existing double tube for use come.
  • the transverse slots preferably extend between one and the other tube. The intervening remaining parts of the longitudinal rib alternating in different directions from the plane of the Longitudinal rib bent out and thus protrude into the heating gas flow inside.
  • the Windings with a rectangular tube shape, flat on each other. This creates between the pipe parts, along the helical or spiral course, instead a linear contact a flat contact. This leads to a completely closed water space, with sufficient sealing to prevent heating gases from escaping prevent. The seal can continue to do so be improved so that the superimposed surfaces of the Intertwine windings by means of profiling.
  • the tube is preferably made of an extruded aluminum profile.
  • the with molded longitudinal rib and the necessary slots in the longitudinal rib provided single or Double pipe can be extruded very easily getting produced.
  • the winding of the tube is after Heating to a suitable temperature, also none Problem.
  • the heat exchanger has a water space in the form a wound tube (1) (Fig. 1-4) or one Double tube 1 '(Fig. 5-7) with a relatively small water volume on.
  • the heat exchanger forms a combustion chamber 2, into which a burner 3 protrudes, and one Combustion gas exhaust 4.
  • the pipe 1 or double pipe 1 ' consists of a preferably a rectangular cross section having extruded aluminum profile, and has a longitudinal rib 5 (Fig. 4, stage A). After this Cross-slits 6 are extruded into this longitudinal rib 5 shaped (Fig. 4, stage B and Fig. 7). Between these Cross slots 6 remain parts 5 'as the remaining parts of the original longitudinal rib 5 left.
  • the tube 1 is then in the plane of the rib wound (Fig. 1-4) or one Double tube 1 '(Fig. 5-7) with a relatively small water volume on.
  • the heat exchanger forms a combustion chamber 2, into which a burner 3 protrudes, and one Combustion gas exhaust 4.
  • stage C Here engage the parts 5 'of the longitudinal rib 5 into each other. she can in the middle of the combustion gas exhaust 4 more overlap or less (Fig. 1). An important aspect is that the direction of the gas flow is constantly changing, and that no core flow occurs in the combustion gas exhaust.
  • the double tube 1 ' is shown in FIG. 5 in the plane of Tube wrapped.
  • the protrude into opposite Directions of parts 5 'bent apart with transverse slots 6 provided longitudinal rib 5 in the combustion gas exhaust 4.
  • the superimposed surfaces of the windings, for the purpose better sealing, by means of a profiling like this complementary mesh as shown in Fig. 2 is.
