Definitions

  • the present invention relates to a central heating installation provided with a hot water circuit for domestic use or sanitary water and comprising a heating device comprising an envelope or ferrule, the lower part of which is provided with a burner, in particular of a gas burner and on which a pipe is wound or not in which the water circulates from the heating circuit, this circuit then passing through a bundle of fins located at the upper part of the envelope on the trajectory of the hot gases escaping from the latter to then be directed to a discharge pipe.
  • the domestic hot water circuit comprises a second conduit in which the heating water circulates, and which crosses the bundle of fins in intimate thermal contact with the first conduit in which circulates the heating water.
  • French Patent No. 1,352,607 describes such a heating installation in which the intimate thermal connection between the first conduit, in which the water from the heating circuit circulates, and the second conduit in which the water from the sanitary circuit circulates, is obtained by joining the two conduits so that they constitute a double-passage tube which crosses the bundle of fins, this tube having a cross section of suitable shape, for example circular or elliptical.
  • BE-A-671 097 also discloses double duct heating installations in which the intimate thermal contact between the two ducts, respectively of the heating water circuit and the domestic water circuit, is obtained by incorporating one of the conduits in the other, these two conduits then being produced in the form of two tubes, possibly concentric, passing through the bundle of fins of the heating appliance, the external surface of the internal tube being applied joined against the inner surface of the outer tube.
  • FR A 1 484 821 - to produce a heat exchanger in which the heating circuit, in its crossing of the fin bundle, is produced in the form of a plurality of flattened tubes connected to each other by elbows and the sanitary water circuit is produced in the form of a tube folded in an S or a pin shape and arranged inside the flattened tubes constituting the duct of the heating circuit.
  • the present invention proposes to provide an improved installation which does not have the drawbacks mentioned above.
  • a central heating installation provided with a hot water circuit for domestic use, or sanitary water, which comprises a heating device comprising a ferrule whose inner part is provided with a burner, in particular of a gas burner, and on which a heating circuit duct is wound or not, which then crosses a bundle of fins located at the upper part of the shell, on the hot gas path, the heating circuit in its crossing of the fin bundle being produced in the form of a plurality of flattened tubes connected to each other by elbows and the domestic hot water circuit being produced in the form of a tube shaped as a pin or serpentine and disposed inside said flattened tubes when crossing the fin bundle, characterized in that: - the tubes of the domestic hot water circuit, arranged in a pin or serpentine in the flattened tubes of the heating water circuit are not in contact with the latter and - The dimensions of said flattened tubes and said tubes are chosen so that the volume of water contained between the flattened tubes and the convolutions of the hairpin tubes is as small as possible.
  • each end of the tubes flattened externally to the fin bundle an end piece which is brazed or welded on said end so as to close it, this end piece having the form of a plate provided with 'a first opening for the connection of the bent tube, ensuring the connection between the coils or pins of the sanitary water conduit and a second opening for the connection of the bent tube which ensures the connection between two consecutive flattened tubes.
  • a transmission surface is provided. thermal between the convolutions of the tube wound in a pin or in a spiral, inside the flattened tubes.
  • said thermal transmission surface is produced in the form of a metal plate comprising partially cylindrical parts matching the shape of the tube shaped as a pin, on which they come to engage, connected by vertical flat parts.
  • the two conduits have an intimate heat exchange in the upper part of the heating appliance where the fin bundle 18 is positioned (part shown in FIGS. 1 and 2).
  • the duct 10 ′ of the circuit in which the heating water circulates is in the form of a plurality of flattened tubes such as 10 ′, which each have a oval cross section, or substantially oval, the major axis of which is arranged vertically.
  • the different flattened tubes 10 ′ arranged in parallel are connected at their ends by bent tubes such as 14.
  • the sanitary water conduit 12 consists of a tube preferably of circular cross section and it is disposed inside the flattened tubes such as 10 ′ which it crosses in the configuration of a pin or a coil so as to considerably increase the heat exchange surface, between the heating water which circulates in the flattened tubes 10 ′ and the sanitary water contained in the tube in pin configuration 12 ′, in its crossing of the flattened tube .
  • each tube 10 ′ constituting a portion of the heating water circuit in its passage through the fin bundle 18, receives a portion in the pin configuration 12 ′ of the water conduit sanitary.
  • the positioning of the tube section in the pin configuration 12 ′ in the flattened tube 10 ′ constituting the heating water conduit, is carried out so that there is no contact between the walls of the tubes 12 ′ and 10 ′.
  • the section of the tube in the pin configuration 12 ′ is chosen so that the volume of water contained between the flattened tube 10 ′ and the pin or coil 12 ′ is as small as possible so that the water circulating in the sanitary circuit 12 takes all the calories from the heating water, without it being necessary to put the accelerator of the heating circuit into operation, the absence of contact between the walls of the tubes 10 ′ and 12 ′ preventing any boiling of the domestic water circulating in the tube 12 ′.
  • the ends of the flattened tubes 10 ′ are closed off according to the invention using end pieces 20 in the form of plates (FIGS. 3 and 4), which have an opening 22 for connecting the bent tubes 16 which provide the connection between two consecutive coils or pins 12 ′ and a second opening 24 for the connection of bent tubes 14 ensuring the connection between two flattened tubes 10 ′ consecutive.
  • the end plates 20 are preferably brazed on the ends of the tubes 10 ′.
  • FIG. 5 illustrates an exemplary embodiment of a fin 18.
  • This comprises a series of openings such as 26, the shape of which corresponds to the cross section of the flattened tubes 10 ′, these fins being successively threaded on the network of tubes parallel 10 ′ on which they are brazed in a known manner (see FIG. 2).
  • the tube 12 ′ arranged in a pin or serpentine is produced in a one-piece structure with the plate 28, the tube and plate assembly being stamped in the form of two half-shells 34 , 34 ′ which are connected by their joint plane 36, and secured by a welding process without filler metal, for example by pressure, ultrasound or others.
  • the invention provides a heating installation ensuring perfect heat exchange between the incorporated circuits of heating water and sanitary water, thanks to a large thermal contact surface obtained without physical contact of the circuits, by the relative arrangement of the two conduits, by the hairpin configuration of the sanitary water circulation conduit tube passing through the flattened tube of the heating water conduit, by the small volume of water contained between each flattened tube and the tube arranged in a pin that it contains and preferably thanks to the arrangement of plastic rings threaded on the tube constituting the sanitary water circuit which keep the latter away from the tube constituting the circuit heating water by eliminating all sources of hydraulic vibration.
