Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • the invention has for its object to further develop the known heat exchangers such that a jacket can be easily attached to the heat exchanger without further fastening elements, which allows the thermal energy lost through a stovepipe to be used.
  • the object is achieved according to the characterizing part of patent claim 1.
  • An essential advantage of the invention is that the device can be safely connected to a stovepipe in a few simple steps without tools and without any additional devices and can be released again. The device therefore allows the thermal energy of a furnace to be better utilized during the heating season. Outside the heating season, it can be easily removed from the stovepipe and placed in a suitable room.
  • Another advantage is that the geometry and the flow conditions in the exhaust system are not changed and that the length of the device is arbitrary. The surface of a unit length of the stovepipe with the device according to the invention is 20 times as large as without the device, whereby a much better use of the heating energy is achieved.
  • the combustion gases rising in a stovepipe 1 heat it, but reach the chimney in a relatively hot state and escape unused into the atmosphere.
  • the hot surface of the stovepipe radiates heat to the surrounding air.
  • the device according to the invention is now placed around the stovepipe 1 and the bandage 2 on which the profile ribs 3 e.g. are fastened with rivets 4, tensioned by a quick-action fastener 5, so the free narrow sides of the profile ribs 3 lie on the outer wall of the stovepipe 1, as a result of which the entire device is held in a force-fitting manner even on vertical pipes.
  • a quick-action fastener 5 tensioned by a quick-action fastener 5
  • the profile ribs 3 do not necessarily need the embodiment shown in the drawing To have a U-shape and to lie on the bandage 2 with its horizontal connecting web. Rather, they can also be arranged upside down so that the horizontal or circular connecting web rests on the stovepipe. This leads to an improvement in heat transfer. Finally, it is also possible to give the profile ribs an L or Z-shaped design. Of these possible embodiments, the last-mentioned has the advantage that on the one hand it can be most easily attached to the bandage by means of rivets and on the other hand it nevertheless forms a wide contact surface for the stovepipe.
