Definitions

  • the invention relates to a space heater for small spaces, in particular for mobile spaces, such as caravans, vehicle and ship cabins or the like, according to the preamble of claim 1.
  • the heat exchanger together with its heating surfaces on both sides is made from a single die-cast or injection-molded piece. It consists of a tube with a circular cross-section, from which inner and outer fins protrude as indirect heating surfaces. At one end, this heat exchanger is closed off by an approximately spherical cap, while at the other open end there is the combustion chamber, from which a cylindrical flame tube projects into the heat exchanger. This flame tube, which is perforated along its entire length, ends at a noticeable distance from the heat exchanger cap and a noticeable distance is kept between it and the inner fin tips.
  • a heat exchanger cylinder with fins protruding inside and outside requires relatively large diameters. If many slats are provided for high performance, a complicated fitting is created. The fins essentially only act like indirect heating surfaces with relatively long passageways, while the remaining surfaces are very small for direct heat transfer.
  • the invention is therefore based on the object of providing an improved heat exchanger for a heater of the aforementioned type which can be produced in a simple manner and which can be produced by a particularly high specific heating excellence.
  • This heat exchanger is suitable both for the direct heating of the room air if it is used as a free heat exchanger in a heater that can be set up as well as in connection with a boiler room jacket, which then surrounds the heat exchanger at a suitable distance and expediently at full height. To increase the flow tion and thus the heating power, this hot air flow can still be acted upon by a blower.
  • a burner 2 which is not described in more detail, in a combustion chamber 1.
  • This flame tube extends upwards in the interior of a heat exchanger 10, where it ends with its upper outlet opening 5 shortly before a ceiling surface 23 of the heat exchanger.
  • a protective plate 7 is placed on the flame tube, which protects the heat exchanger top surface 23 from overheating.
  • the flame tube is formed from a suitable and appropriately surface-treated sheet metal blank, at least one expansion fold (not visible) being expediently formed along a surface line to absorb thermal expansions that occur.
  • the heat exchanger 10 expediently a shaped piece made of an aluminum alloy, forms an annular space 11 at its open end through a base cylinder 13.
  • a base collar 14 can also be designed to hold the heat exchanger on a base attachment (not shown).
  • An outlet connection 12 leads from the annular space 11 for the extraction of the combustion gases to the outside.
  • the heat exchanger is formed by a wave jacket 15. This consists of evenly running around the circumference Waves 16, the outer wave crests 18 and inner wave valleys 17 each lie on an imaginary circle.
  • the shaft walls 19, which delimit the inwardly open shaft channels 20, are approximately parallel to one another.
  • the combustion gases flow downwards after exiting the flame tube and deflected at the ceiling surface 23, where they are taken up by the annular space 11 and finally discharged to the outside through the outlet connection 12.
  • the inner ren wave channels 20 are closed at the top by deflecting walls 25, which slope obliquely outwards and thereby form favorable deflecting surfaces for the combustion gases.
  • the annular space 11 formed by the base cylinder 13 is delimited on the outside by the transition walls 26.
  • the flame tube lies directly on the inner surfaces of the shafts 16, the heat is transferred directly from the flame tube to the heat exchanger.
  • the flame tube 3 adjacent to the wave troughs 17 closes off these wave channels, so that the combustion gases are divided into a large number of individual streams, which fall down in the form of relatively narrow flow layers and are surrounded by relatively large heating surfaces. In this way, there is a very even distribution of the combustion gases and thus also a uniform heat emission over the entire extent of the heat exchange. shers.
  • the annular space 11 acts here as a collecting space for the falling combustion gases and thus ensures their undisturbed extraction, even if there is only one outlet connection at one point.
  • the heat exchanger according to the invention can or the like without a housing jacket. Cladding are set up and act directly on the room air, which flows up and warms up along its outer shaft channels 21. A more powerful device can be used in conjunction with reach a heating chamber jacket 28 which expediently surrounds the heat exchanger at full height and at a short distance from the wave crests 18. An air inlet opening 29 at the level of the annular space 11 allows sufficient air access, a slight expansion 31 of the heating chamber jacket in the lower area ensuring a uniform distribution of the inflowing air around the heat exchanger. Above the heat exchanger, the heating chamber jacket is brought together to form an air outlet opening 30, from which the hot air can either flow directly into the room to be heated or flow into a pipe system.
  • the invention is not limited to the illustrated embodiment.
  • a precisely cylindrical arrangement of the heat exchanger shaft jacket 15 and / or of the flame tube 3 is also possible, although a predetermined conicity, which takes into account the gas concentration due to cooling and thereby avoids a flow delay, has a more advantageous effect.
  • the jacket shafts do not necessarily have to extend over the entire length of the heat exchanger, which can be the case, for example, if they can only start in an upper region due to a different design of the combustion chamber and / or the hot air duct. If, in the illustrated heat exchanger, the jacket shafts line up in close succession, this includes a different design with e.g. wider wave valleys and / or mountains, which can also be different, not.
