Definitions

  • the invention relates to a heater according to the preamble of patent claim 1.
  • a heater of the type mentioned is according to the EP 1 562 006 A1 known.
  • This consists of a helically coiled, an approximately rectangular flow area having heat exchanger, a combustion chamber in which a burner for liquid or gaseous fuels arranged and which is axially bounded by at least one lid member and radially from the heat exchanger, a housing consisting of a shell part and the at least one cover element is formed and which encloses the heat exchanger to form an exhaust passage, wherein the heat exchanger at its cover element facing the end an axially oriented aligned, tubular connecting piece for supplying or discharging a heat transfer medium (Heiz Vietnamese), wherein the cover member provided a shape adapted opening is, in which the connecting piece is formed plugged.
  • the described solution has two cover elements. But just as well, a cup-shaped shell part construction is conceivable, which is closed only with a cover element.
  • the heater may also have more than one helical tube heat exchanger: this protest is on the WO 2007/087801 A1 (see in particular FIG. 6 ), which shows a double helix with a common connecting piece.
  • the invention has for its object to further improve a heater of the type mentioned.
  • the cover element has a cavity for receiving the heat transfer medium, in which the connecting piece is formed ausmündend.
  • connection pipe does not open directly into a pipe of the heating circuit, but rather into a cavity designed as a collecting space.
  • the heat transfer medium thus flows either from the cavity in the heat exchanger or from the heat exchanger into the cavity, wherein the cavity itself - to avoid a hydraulic short circuit - preferably distanced to the connecting piece either the supply or return connection of the heating circuit is connected.
  • the heat transfer medium is thus passed through the cavity, which leads in consequence in a surprisingly simple manner to a water-cooled cover element.
  • the solution according to the invention proves to be particularly advantageous if, as will be described in more detail below, a plurality of helical tube heat exchangers are provided, in particular if each helical tube heat exchanger has its own connecting piece on the cover element side and this has a number of openings corresponding to the number of heat exchangers open out the cavity according to the invention, which then advantageously leads to the fact that the heat transfer medium is uniformly mixed before entering the heat exchanger or in the heating circuit flow.
  • heater consists of at least one ( FIG. 1 and 5 show one, FIGS. 6 and 7 show three) helically coiled, an approximately rectangular flow area having heat exchanger 1, a cylindrically shaped combustion chamber 2, in which a burner 3 for liquid or gaseous fuels (gas or oil burner) arranged and the axially of at least one cover element 4 and radially from the heat exchanger. 1 is limited, a housing 5, which is formed of a cylindrical shell part 6 and the at least one cover member 4 and the heat exchanger 1 to form an exhaust passage 7 encloses.
  • the heat exchanger 1 at its cover element facing the end 8 an axially oriented (parallel to the heat exchanger coil axis) aligned, tubular connecting piece 9 for supply or discharge of a heat transfer medium, wherein the lid member 4 is a form-fitting opening 10 is provided, into which the connecting piece is designed plugged.
  • Both the connecting piece 9 and the opening 10 have a circular cross section, wherein between the connecting piece 9 and the opening 10, a sealing element 20, preferably an O-ring, is arranged.
  • the cover member 4 has a cavity 11 for receiving the heat transfer medium, in which the connecting piece 9 is formed ausmündend.
  • FIGS. 1 . 6 and 7 are each provided at both housing ends or both ends of the combustion chamber 2 cover elements 4, each having a cavity 11.
  • FIG. 5 is provided only on the right cover element 4 of the cavity 11 according to the invention.
  • the combination of cavity 11 and plug-in connection piece 9 leads, as explained above, to an easily assembled construction, which moreover has the advantage that the cover elements 4 are directly water-cooled.
  • FIG. 3 this is designed in the form of Leittrenn familiarn, the return port of a heating circuit for the supply of heat transfer medium to the cavity 11 is connected to the connection port 17 (not shown separately, as readily imaginable).
  • the heat transfer medium (heating circuit water) flows through after entry into the connection opening 17 and guided from the flow guides 12, the cover member 4 until it reaches the opening 10 (shown only indicated) and from there via the connecting piece 9 in the heat exchanger 1.
  • a venting connection 13 directly communicating with the cavity 11 is provided at the upper end of the cover element 4.
  • FIG. 4 which shows a lid member 4, which is provided for receiving the burner 3 with a receiving opening 19, the heat transfer medium from the opening 10 into the cavity 11 flows. There, an annular channel is formed as a flow guide 12, which then leads the heat transfer medium to the connection opening 17 ,
  • the cover element 4 is according to FIG. 4 connected to the flow of the heating circuit.
  • cover element 4 is according to Figure 1 to 4 in that it is formed from two shells 14, 15 enclosing the cavity 11, wherein a first shell 14 (outer shell) forms an outer surface of the housing 5 and a second shell 15 (inner shell) forms an inner surface in the combustion chamber 2. Furthermore, the said flow guide 12 is formed in each case on such a shell 14, 15, wherein further the shells 14, 15 are formed circular disc-shaped and between the shells 14, 15, a sealing element 16 (only indicated) is arranged.
  • the shells 14, 15 according to the FIGS. 1 to 4 are produced by casting and preferably consist of a cast aluminum.
  • the cover elements 4 according to the Figures 5 and 6 are also cast, but in the so-called core casting process, ie these cover elements 4 are integrally formed, wherein the cavity 11 is generated by a corresponding lost core during casting.
  • the cover element 4 is formed in shape matching the combustion chamber side to the coiled heat exchanger 1. This is good at paragraphs 18 in the Figures 2 and 4 recognizable.
  • FIGS. 6 and 7 advantageously provided that three helically coiled, nested heat exchanger 1 are used to form a particularly large heater.
  • the lid member 4 provided with the cavity 11 forms, as already explained, a collector into which the three connecting pieces 9 of the heat exchangers 1 are opened by 120 °.
