Definitions

  • the invention relates to a boiler.
  • a generic boiler is known from the patent EP 1 989 499 B1 , It describes a heat exchanger with one or more composite modules.
  • the assembled modules form a combustion chamber in the upper area. In the lower area there is a common outlet opening.
  • Each module is inexpensively formed by two deep-drawn basic elements. Between the combustion chamber and the common outlet opening, the assembled modules form a plurality of rib-shaped chambers, which have a grooved surface outside the modules for better heat transfer from the hot gas carried inside the modules to the water to be heated.
  • the modules from which the heat exchanger can be modularly assembled have an application area and exit area with respective openings at which the modules are assembled.
  • the combustion chamber is provided at the opening of an end module.
  • the module or modules of aluminum casting or stainless steel sheet are particularly suitable for heat exchangers either because of the good thermal conductivity or because of the high corrosion resistance.
  • a module is formed from at least one deep-drawn sheet metal. As a result, a module can be produced particularly inexpensively.
  • the module is formed from at least one tube section formed by hydroforming. This has the advantage that in this case a hollow body can be produced with only a small number of welds. This is advantageous for the corrosion resistance.
  • FIG. 1 represents a heating boiler according to the invention in section.
  • a heat transfer medium usually water, heated.
  • the water to be heated flows in via a return connection 10, is heated by the heat exchanger 3 and flows out via the flow connection 9 in order, for example, to heat a radiator and / or a service or drinking water storage and / or drinking or service water.
  • the heat exchanger 3 is constructed from one or more modules 4 and is similar to a ribbed heater.
  • the modules 4 are designed substantially plate-shaped and have an inlet side in the upper region and an outlet side in the lower region.
  • the module 4 is essentially a flat hollow body, which is flowed through in the interior of the hot gas during operation.
  • an entrance side 5 is provided, which is open on both sides.
  • an exit side 6 is provided, which is also open on both sides.
  • the module can be made for example of aluminum casting or stainless steel sheet. In cases where the module is made of sheet metal, this may for example be welded together from two deep-drawn sheets and / or comprise a hydroformed formed pipe section.
  • the modules 4 are combined to form a heat exchanger 3.
  • On the outlet side of the heat exchanger 3 is connected to an outlet 7 for the exhaust gas.
  • the second open side on the outlet side 6 of the heat exchanger 3 is closed by a cover 12.
  • On the inlet side of the heat exchanger 3 is connected on one side with a combustion chamber 2 and on the other side with a lid 11.
  • the combustion chamber 2 is connected directly to a burner or a burner assembly 1.
  • the combustion chamber 2 is thus advantageously outside the heat exchanger 3. This ensures that the modules 4 are not burdened with the high peak temperatures occurring in the combustion chamber 2, whereby limescale deposits are reduced by the water on the outside and corrosion on the inside.
