Definitions

  • the invention relates to a heating shaft according to the preamble of the independent claim.
  • a heating shaft is e.g. known from DE-A-2 221 801.
  • the aim of the invention is to avoid this disadvantage and to propose a heat exchanger of the type mentioned in the introduction, in which a safe flow is also ensured in the upper regions of the double jacket.
  • the supply or return is connected to one of the two attachments and the other attachment is connected to a branch of the finned tube. This ensures that a partial flow of the total water throughput flows through the attachments.
  • the latter is preferably provided with beads according to claim 4.
  • the outer and inner walls are not only connected to one another along the upper and lower edges, but also at a number of locations distributed over the outer and inner walls. This results in a very rigid construction of the heating shaft, so that its walls can be made relatively thin.
  • the beads lead to stiffening of the walls and a large number of connection points, which are expediently formed by welding points, prevent bulging of the walls due to the internal pressure.
  • the measures according to claim 6 have the advantage that no pipe bends are required for the connection of the heating shaft, which is cooled by the medium to be heated, with the tubes of the finned heat exchanger and the connection of the tubes of the finned heat exchanger with one another, so that a noticeable space saving results. In addition, this also results in a reduction in the outlay for producing the heating shaft and the finned heat exchanger.
  • Claim 7 ensures that the flow is supplied with the slightly higher temperature water from the upper area of the double jacket and the flow connection can still be arranged in the lower area.
  • the channel can be formed by a bulge, preferably on the outside of the double jacket. It can also be provided that the channel is also connected in its lowermost region to the interior of the double jacket via an overflow opening. This makes it possible to largely completely empty the double jacket, even though the channel leads away from the uppermost region of the double jacket. In normal operation, the overflow opening does not lead to any significant mixing of the water drawn off via the channel with the water located in the lower region of the double jacket.
  • a vent tube can also be provided.
  • a slight negative pressure is generated, as a result of which any gas bubbles and pockets that are formed are suctioned off and transported away via the ventilation tube and the outlet connection.
  • the measures according to claim 9 ensure that the suction opening of the vent tube is located in the area in which gas or air bubbles and pockets are most frequently formed. In this way, the air heater can be operated largely free of air bubbles. In addition, there is no need for the ventilation tube to pass through a wall of the double jacket.
  • vent tube run outside the double jacket or / and for the vent valve to be arranged in accordance with claim 11.
  • a double jacket 1 is provided with attachments 2 on two opposite sides, in the embodiment according to FIG. 1 the front attachment is connected to the double jacket 1 via a front constriction 3.
  • a finned tube 4 is arranged between the two attachments 2, the fins 5 of which are held between the attachments 2.
  • the water pipe 6 held in the fins 5 is laid in a serpentine line.
  • the one attachment 2 is connected via a pipe 7 to the water pipe 6 of the finned pipe 4, the two attachments 2 being connected in series with one another via a pipe 8.
  • the lead 9 is connected to that attachment 2, which is not connected to the water tube 6 of the finned tube 4 via the tube 7, namely at the end of the attachment 2 which is flowed through last in the flow direction.
  • the heating water first flows through the lamella tube 4, a part of the water flow entering the one attachment 2 of the double jacket 1 and flowing through it. This partial flow enters the second attachment 2 via the pipe 8.
  • the main flow enters the lower part of the double jacket 1 in the corner region thereof via a bend 10 adjoining the finned tube 4. There the water flow divides and flows over a wide and long side of the double jacket 1 to the connection of the lead 9th
  • the water to be heated flows through the connection 11 of the water pipe 6, which is connected to the return line, into the finned tube 4 and occurs at the flow connection 9, after flowing through the finned tube 4 and the double jacket 1 together with attachments 2.
  • the constriction 3 is only at the front, so that the water can get from the lower part of the double jacket 1 to the connection of the flow 9 arranged in its attachment 2.
  • the constriction 3 is missing between the double jacket 1 and the attachments 2, which are likewise connected to one another via a tube 8. Furthermore, the connection of the water pipe 6 of the finned pipe 5 to one of the attachments 2 is also missing.
  • the water after flowing through the finned tube 6 via the elbow 10 into the double jacket 1 in one corner area. From there, the water flow divides, so that the two longitudinal sides of the double jacket 1 are flowed through in parallel in the same direction.
  • the attachments 2 are connected to the water pipe 6 of the finned pipe 4 via the double jacket 1.
  • the water flow is divided into a partial stream flowing through the actual double jacket 1 and a partial stream flowing through the top section 2 thereof Partial flow, wherein the partial flow flowing through the attachment 2 not connected to the feed 9 is fed via the pipe 8 to the connection of the feed 9.
  • the attachment 2 is separated from the double jacket 1 via a constriction 3 which extends over most of the length of the attachment 2.
  • a channel 16 is formed on one end of the attachment 2, which extends downward to a connection 14 to which, for example, the flow of a heating circuit or other heat consumer can be connected.
  • the constriction is very deep, so that only a small clear cross section remains, which is sufficient, however, to allow any gas bubbles escaping from the heating water to pass through, but not to enable a noteworthy water exchange. It is therefore possible to introduce water into the attachment 2 via a connection 12 in the latter and to force a flow which ensures that any gas bubbles that are accumulated are entrained.
  • the channel 16 is expediently formed by an outwardly projecting bulge 15 of the outer wall 18 of the double jacket 1 together with the attachment 2, a cover 13 extending essentially along the outer wall 18 of the lower area of the double jacket 1 being arranged in the area of the channel 16, which is connected at the top to the inner wall 19 of this area of the double jacket 1.
  • the two attachments 2 of the double jacket 1 are connected to one another via a tube 8.
  • the water is introduced into the lower region of the double jacket 1 via the pipe socket 20 and into the attachments 2 via the connection socket 12.
  • an overflow opening 17 is arranged in the lowermost region of the cover 13, which enables a practically complete emptying of the double jacket 1, for example for dismantling from a heater, although the connection 14 via the channel 16 is also included the uppermost area of the double jacket or its attachment 2 is connected.
  • FIGS. 6 and 7 differs from that according to FIGS. 3 to 5 only in that the channel 161 connecting an attachment 2 to the connection 14 has a kink and extends to the narrow side of the lower part of the double jacket 1.
  • an overflow opening is arranged in the area of the connection 14 in the cover separating the channel 161 from the lower area of the double jacket 1.
  • a heating shaft 1a as a combustion chamber according to FIGS. 8 to 11 is designed as a double jacket 1, as can be seen from FIG.
  • the inner wall 19 is not shown in FIGS. 8, 9 and 10.
  • a space 21 through which a medium to be heated, for example water, can flow is provided between the outer wall 18 and the inner wall 19.
  • the outer wall 18 is connected in some areas to the inner wall 19, beads 22 being arranged distributed over the surface of the outer and inner walls 18, 19, the bottoms of which lie against one another and allow additional connection points there, for example welding points, in order to increase the rigidity of the double jacket 1 to increase and avoid bulging under pressure.
  • the double jacket 1 is provided with an inlet connection 11 and an outlet connection 14 for the medium to be heated.
  • This vent tube 24 leads to the outlet connection 14 and opens essentially in the direction of the axis and in the flow direction of the medium of the outlet connection 14, as a result of which a negative pressure is created in the region of the mouth opening of the vent tube 24. This is due to the flow of the medium through the outlet connection 14.
  • This negative pressure acts via the ventilation tube 24 in the upper region of the heating shaft 1 a, where the ventilation tube 24 has its inlet end, whereby any air bubbles and pockets that accumulate in this region are sucked off via the ventilation tube 24 and transported away through the medium flowing through the outlet connection 14.
  • a vent screw is provided in the uppermost region of the same for venting the double jacket 1 during the first filling, which is kept open during filling and is closed tightly after the double jacket 1 has been completely filled.
  • This bleed screw is located in the bleed nozzle 23.
  • vent tubes 24 lead into the outlet connection 14, which lead to the uppermost regions of the two side walls 25, 26, between which the tubes of the fin heat exchanger, not shown, with fins, the deflection chambers 27 of which are held are visible.
  • the heating shaft 1a is made of stainless steel sheet by a double jacket 1, which encloses an interior 28 provided with an atmospheric gas burner and which is formed by tightly connected outer walls 18 and inner walls 19.
  • the two walls 18 and 19 are tightly connected in the upper and lower region of the heating shaft 1a by means of weld seams 29.
  • An intermediate space 21 remains between the outer and inner walls 18, 19 that can be produced and then soldered from copper sheet, and the medium to be heated flows through it during operation.
  • the space 21 extends, as can be seen from FIGS. 17 to 19, over all four walls of the heating shaft 1 a.
  • Beads 22 are incorporated into the inner and outer walls 19 and 18, the beads 22 arranged in the inner wall 19 and outer wall 18 being arranged essentially congruently.
  • the bottoms 40 of the beads 22 of the inner wall 19 lie against the bottoms 40 of the beads 22 of the outer wall 18, the bottoms 40 of the beads 22 being connected to one another by welding points.
  • the outer wall 18 of the side walls 25 and 26 is provided with bulges 41, which are surrounded by areas 42 in which the inner wall 19 bears closely against the outer wall 18, the bulges 41 extending over two openings 38 of the corresponding inner wall 19 and as deflection bends serve for the water flowing through the tubes 31.
  • a bulge 43 further connects that region of the side wall 25 in which there is a space 21 between the outer wall 18 and the inner wall 19, with a tube 31 of the heat exchanger 30 so that the water can flow from the space 21 into the heat exchanger 30.
  • the inlet and outlet connections are arranged on the outside of the side wall 26.
  • FIG. 14 shows a heating shaft 1 a in which a gas burner 68 which is fed from a gas line 67 provided with a gas valve 66 is arranged, the heating shaft 1 a being formed by a double jacket 1 which is filled with water. This has a constriction 3 in its upper region.
  • the gas burner 68 is assigned to the lower region 84 of the heating shaft 1a, whereas the heat exchanger 30 is assigned to the upper region 83 facing away from the gas burner 68.
  • the arrangement of gas burner 68 and heat exchanger 30 is common to all embodiments.
  • a vent valve 72 designed as an automatic float valve is arranged, which is located with its connecting line 73 above the double jacket 1, the gas accumulated in the area 71 being able to be discharged via the vent valve 72.
  • the constriction 3 is formed from squeezing points 74 arranged in a row, in which the two walls of the double jacket 1 practically abut one another, but free passages 75 are provided between these squeezing points 74.
  • the gas water heater according to FIGS. 14 and 15 can be used as a domestic water heater or as a heat source for a circulating heater.
  • FIGs 16 to 19 correspond in terms of operation to Figures 8 to 11, wherein the ventilation tubes 24, instead of being arranged in the space 21, are located on the outer wall 18 and only the pipe ends 85 through the outer wall 18 or the connection 14 in the Protruding space.
  • This arrangement has the advantage that there is no obstruction of the pipes when joining the inner and outer shafts. It is also possible to replace the pipes at a later date.
