Definitions

  • the invention relates to a heater according to the preamble of patent claim 1.
  • a heater of the type mentioned is from the patent document EP 0 632 239 A1 known.
  • This heater consists of a combustion chamber and a trained to conduct hot, generated in the combustion chamber flue gas flue gas, which has an inlet region and an outlet region and is connected to the combustion chamber connected via the inlet region and wherein in the hot gas to heat transfer from the hot exhaust gas to the Schugaszug spaced from each other, a wall thickness having heat transfer ribs are arranged.
  • These heat exchanger fins which may be formed, for example, as an extruded aluminum profile or also from a folded sheet metal, extend unchanged in cross section from the inlet region to the outlet region.
  • the Schugaszug itself is surrounded outside in a known manner by the heater flowing through the heating circuit water.
  • a heater according to the preamble of claim 1 is known from the patent document DE 10 2007 060 508 A1 known.
  • the invention has for its object to improve a heater of the type mentioned.
  • a heater is to be created with a further improved heat transfer in the field of Schushippes from the exhaust gas to the Schunikwaser.
  • the wall thickness of the heat transfer ribs is greater or the heat transfer ribs are thick-walled on the side of the entry region than on the side of the exit region and if a wall of the heating gas duct arranged between the exhaust gas and the water has a wall thickness which smaller than the smallest wall thickness of the heat transfer rib is formed.
  • the solution according to the invention is thus distinguished by the fact that constructional measures are taken on the hot gas flue which take into account a flow of exhaust gas which cools between the inlet and outlet regions.
  • a thicker-walled heat transfer rib is used than at the exit region.
  • the heater shown in the figures consists in a conventional manner of a combustion chamber 1 and a trained to conduct hot, in the combustion chamber 1 with a not-shown burner exhaust gas flue 2, which has an inlet region 2.1 and an outlet region 2.2 and is formed connected to the combustion chamber 1 via the inlet region 2.1 and wherein in the heating gas 2 for heat transfer from the hot exhaust gas to the heating flue 2 spaced apart, a wall thickness having heat transfer ribs 3 are arranged of a metallic material.
  • the combustion chamber 1 is connected to a plurality of (here four) heating gas trains 2 through which the exhaust gas flows.
  • the Schugaszug 2 itself has in this case a (approximately) rectangular cross-sectional area with a length and a width, wherein the length corresponds to a multiple of the width.
  • the heating gas 2 is formed connected via the outlet region 2.2 with an exhaust gas collecting chamber 4.
  • the combustion chamber 1 is arranged above the heating gas train 2 and this above the exhaust gas collecting chamber 4.
  • the exhaust gas collection chamber 4 is in turn in a known manner (and therefore not shown separately) connected to a chimney of a building or the like.
  • FIG. 2 shows the still relatively thick-walled and with comparatively large distance from each other arranged heat transfer ribs 3 in the inlet region 2.1 (section AA).
  • FIG. 3 shows the comparatively thin-walled and with comparatively small distance from each other arranged heat transfer ribs 3 in the outlet region 2.2 (section BB).
  • FIGS. 1 to 3 thus a basic constellation.
  • the decrease in the volume of the exhaust gas with increasing distance from the combustion chamber 1 thus, again expressed in other words, according to the invention provided that a) the wall thickness of the heat transfer fin 3 with increasing distance from the combustion chamber. 1 is formed smaller and / or that b) the distance between the heat transfer ribs 3 is formed smaller with increasing distance from the combustion chamber 1.
  • the named Change from zone to zone can take place continuously or, which is structurally simpler, stepwise.
  • the heating gas 2 flows through the exhaust gas on the one hand and on the other surrounded by water (in particular Schunik) is also provided for a particularly good heat transfer according to the invention, that between The exhaust gas and the water disposed wall of the heating gas 2 has a wall thickness which is smaller than the smallest wall thickness of the heat transfer rib 3 is formed.
  • the wall of the hot gas flue 2 is formed from a metallic sheet material.
  • the heater according to the invention in which also a wall of the hot gas flue 2 and the heat transfer fins 3 are formed as separate components, particularly preferably provided that the heat transfer ribs 3 as support of the wall of the hot gas flue 2 against the pending from the outside water pressure are formed.
  • the heat transfer ribs 3 are preferably in one (see in particular FIG. 2 ) or multi-row (see in particular FIG. 3 ) and multiple S-shape arranged in the hot gas flue 2, wherein the proviso "multiple" simply means that several S-shapes are arranged in a row in the longitudinal direction.
  • the heater according to the invention is to be operated as a so-called condensing boiler to achieve high efficiency, it is also particularly preferred that the Schugaszug 2 and / or the heat transfer fins 3 is formed from a resulting from the exhaust condensate material or are.
  • FIGS. 4 and 5 a further embodiment of the hot gas flue invention is shown.
  • This Thompsongaszug is characterized in that the heat transfer ribs 3 in a - relative to a flow of hot exhaust gas - central region of the Schugaszuges 2 have more distance to the inlet region 2.1 of the Schugaszuges 2 than at an edge region of the Schugaszuges 2. Expressed again in other words, a notch is thus provided in the central region of the heat transfer ribs 3 at the entry region.
  • This proviso has the advantage that the hot, especially in the central region in the Schugaszug inflowing First, the exhaust gas can cool down a little before it comes into contact with the heat transfer rib 3. At the same time, however, somewhat prolonged formation of the heat transfer fins 3 is still provided by the less hot exhaust gas applied edge region for a sufficient support of the wall of the Schugaszuges 2.
  • this heating gas 2 has a total of three different zones.
  • the entry-area heat transfer ribs 3 are shown, which, in order to be able to withstand the hot exhaust gas, are correspondingly thick-walled and arranged at a relatively large distance from one another.
  • the heat transfer ribs 3 in the middle and outlet areas are significantly thinner walls and arranged at a smaller distance from each other.
  • FIG. 4 provided that the heat transfer fins 3 a zone (ie in a region in which the wall thickness and the distance of the heat transfer fins 3 does not change) from two, seen in the flow direction of the hot exhaust gas successively arranged sections 3.1, 3.2 are formed, wherein between the sections 3.1, 3.2 a gap is provided and the sections 3.1, 3.2 are preferably arranged with offset from one another.
  • This proviso serves to swirl the flow in this zone to increase the heat transfer again.
