Definitions

  • the invention relates to a heating heat exchanger.
  • a plurality of similar heat exchanger coils are arranged coaxially one behind the other.
  • Each heat exchanger coil has an input and an output.
  • the heat exchanger coils may be partially connected in parallel, so that in each case the inputs and outputs of adjacent heat exchanger coils are connected to each other in flow and return headers.
  • the helices may also be connected in series so that the output of a heat exchanger coil is connected to the input of an adjacent heat exchanger coil.
  • a plurality of blocks of parallel-connected heat exchanger coils may be serially connected such that the flow header of a block of parallel-connected heat exchanger coils is connected to the return header of an adjacent block of parallel-connected heat exchanger coils.
  • an exhaust collecting housing is mounted around the heat exchanger coils.
  • a burner is mounted centrally on one side over a partial length.
  • a partition separates the interior of the coils into two chambers. During operation of the burner, the hot exhaust gases of the burner on one side of the partition flow from the inside through part of the heat exchanger coils then to flow on the other side of the partition from outside to inside through the heat exchanger coils. The exhaust gases are collected after the heat exchange and then discharged via an exhaust pipe.
  • the dividing wall becomes very hot and, on the one hand, already heats cooled exhaust gas on the side facing away from the burner.
  • the partition radiates radiant heat via the exhaust gas discharge.
  • the object of the invention is a higher thermal efficiency of the heat exchanger.
  • FIG. 1 shows a heater core 1 with a housing 8 and a centrally disposed therein metallic primary heat exchanger 2, which has four coaxially arranged heat exchanger coils 3.
  • the housing 8 is approximately cylindrical, so that the two outer juxtaposed heat exchanger coils 3 with the respective end walls 15, 16 are flush. Radial to the heat exchanger coils 3 is up to the housing 8, an annular gap 17.
  • the individual heat exchanger coils 3 are made EP 678186 B1 known.
  • a fuel gas burner 9 is arranged coaxially to the heat exchanger coils 3.
  • the burner 9 is arranged on the first end wall 15 of the housing 8 perpendicular to the central axis of the heat exchanger coils 3.
  • Each heat exchanger coil 3 has an input 4 and an output 5.
  • each case two heat exchanger coil 3 are fluidically interconnected, so that their inputs 4 are fed from a common return collector 6 and the Outputs 5 lead into a common flow collector 7.
  • the return line 12 of a heating circuit is connected to the return header 6 of the two heat exchanger coils 3 on the side of the exhaust gas outlet 10.
  • the flow collector 7 of the two heat exchanger coils 3 on the side of the exhaust gas outlet 10 is connected to the return header 6 of the two heat exchanger coils 3 on the side of the burner 9.
  • the flow collector 7 of the two heat exchanger coils 3 on the side of the burner 9 is connected to the flow line 13 of the heating circuit not shown.
  • a partition plate 11 is arranged between two heat exchanger coils 3, which separates the interior of the heat exchanger coils 3 into two subspaces.
  • the partition plate 11 consists of two opposite plates, which form a water channel.
  • the partition plate 11 is connected both to the flow collector 7 and return collector 6 on the side of the exhaust gas outlet 10.
  • FIG. 2 shows this connection.
  • Parallel to the partition plate 11, the heat exchanger coil 3 opens on the side of the exhaust gas outlet 10 in the same flow 7 and return collector. 6
  • FIG. 3 the flow pattern in the water-cooled partition plate 11 from the input 4 to the output 5 is shown.
  • a so-called ying-yang water supply 14 provides for a Multiple diversion to avoid dead water areas and to allow a flow through the entire area.
  • a meander-shaped flow guide is suitable for this purpose.
  • the hot exhaust gases initially flow outward on the side of the partition plate 11 remote from the exhaust gas outlet 10 through the heat exchanger coils 3 and release thermal energy to the heat exchanger coils 3. Part of the energy is also delivered to the partition plate 11 via radiation and convection.
  • the exhaust gases are then directed on the side facing away from the burner 9 of the heat exchanger coils 3 to the heat exchanger coils 3 next to the exhaust gas outlet 10 and flow through the local heat exchanger coils 3 inside and give this thermal energy to the heat exchanger coils 3 from.
  • thermal energy is transferred to the water-cooled partition plate 11 here as well.
  • the cooled exhaust gases flow through the exhaust outlet 10, from where they are conducted into the environment.
  • the partition plate 11 may optionally have a contour or ribs on the outside to increase the heat exchanger area.
  • the number of heat exchanger coils 3 varies; the greater the power, the more heat exchanger area needed to transmit the thermal power.
