Definitions

the invention relates to a heating boiler according to the preamble of patent claim 1.
a boiler of the type mentioned is out EP 0 970 327 B1 known.
This consists of a combustion chamber, the veridendig with cover elements and formed by a helically coiled gap heat exchanger is formed.
this boiler consists of a gap heat exchanger enclosing housing, which is formed from the cover elements and a shell part, wherein the gap heat exchanger for forming an accessible from outside the housing connecting piece has a free, an outer cylinder circumference of the gap heat exchanger superior end.
FIG. 4 This document can only assume that the shell part corresponding through holes are provided.
the invention has for its object to improve a boiler of the type mentioned.
a boiler is to be created with as easy to produce through holes.
a passage opening for the connecting piece is formed on the cover element.
the solution according to the invention thus characterized by the fact that not the jacket part, but the lid member itself is provided with a passage opening for the connection piece.
This proviso has the advantage that a complicated design of a through hole on the shell part can be omitted, whereas the particular cast technology training the passage opening on the lid member comparatively easy to manufacture and beyond, which will be explained in more detail below, also good seal.
the illustrated boiler consists of a combustion chamber 1, which at both ends with lid elements 2 ver and (at least partially) is formed by a helically coiled gap heat exchanger 3 is formed. Furthermore, the boiler consists of a gap heat exchanger 3 enclosing housing, which is formed from the cover elements 2 and a shell part 4, wherein the gap heat exchanger 3 to form an accessible from outside the housing connecting piece 5 has a free, an outer cylinder circumference of the gap heat exchanger 3 outstanding end ,
cover elements 2 it is preferably provided that these are formed by casting technology, in particular as an aluminum die casting. Furthermore, it is provided (not shown separately) that a burner for liquid or gaseous fuels is arranged on one of the cover elements 2 (in this way the combustion chamber is closed towards the outside, for example a thermal insulation block or the like on the cover element 2) provided for completion of the combustion chamber 1).
a burner for liquid or gaseous fuels is arranged on one of the cover elements 2 (in this way the combustion chamber is closed towards the outside, for example a thermal insulation block or the like on the cover element 2) provided for completion of the combustion chamber 1).
FIG. 1 and 3 it can be seen, while the lid member 2 is annular and about the same extent in the radial extent as the gap heat exchanger 3 is formed.
the gap heat exchanger 3 has in a conventional manner a (substantially) rectangular flow area, with short sides of the rectangle forming its inner and outer peripheral surface.
the preferably circular on the outer circumference cover element 2 is formed inserted in a conventional manner in the shell part 4. After insertion, the edge of the preferably cylindrical shell part 4, as particularly good FIG. 1 visible, flanged for fixing the lid member 2. It is further provided that the housing is formed the gap heat exchanger 3 to form an exhaust chamber 12 enclosing. In addition, in particular with reference to FIG. 5 on the shell part 4, an exhaust port 15 and a condensate drain 16 is provided.
the cover element 2 in the region of the passage opening 6 in the axial direction of the gap heat exchanger 3 seen thicker than the connecting piece 5 is formed.
the passage opening 6 is up to a the shell part 4 facing the outer periphery of the lid member 2 is formed reaching, the outer periphery (with reference to FIG. 2 and 3 ) is formed as an outer peripheral surface 11.
connection piece 5 suitably trained arrangement area 7 (for the connection piece 5) provided, wherein also (see in particular FIG. 4 ) of the connecting piece 5 is particularly preferably formed as a straight, also having a substantially rectangular flow cross section exhibiting pipe section.
a preferably approximately rectangular recess 8 is provided on the shell part 4 in the region of the passage opening 6.
This recess 8 on the shell part 4 in this case has a circumferential width (length), which corresponds to a circumferential width (length) of the through hole 6.
the recess 8 is open to the edge of the shell part 4, ie the cover element 2 can be inserted together with the gap heat exchanger 3 in the shell part 4.
the depth or width of the recess 8 is selected so that it corresponds to the thickness of the gap heat exchanger 3 plus the outer wall thickness of the cover element 2 in the region of the through hole 6.
a sealing element 9 is arranged between the cover member 2 and the shell part 4, in particular for sealing the exhaust chamber 12 relative to an environment of the housing.
This sealing element 9 is preferably made of an elastic material, in particular rubber.
a groove 10 for receiving the sealing element 9 is provided.
the sealing element 9 comprises an annular annular seal part 9.1 which fits the groove 10.
the sealing element 9 also comprises a surface sealing part 9.2 which fits the outer circumference of the cover element 2. This is how the comparison between FIG. 1 and 6 shows, larger than the recess 8 formed on the shell part 4.
the surface sealing part 9.2 has a the connecting piece 5 accurately enclosing sealing passage 9.3.
