Definitions

  • the present invention relates to a mixed heat exchanger of the type used to obtain a heat transfer between three fluids in movement without contact of these fluids with one another, one of these fluids being gaseous.
  • Such heat exchangers are known and used in numerous applications and come in various forms generally comprising several enclosures each separated by a common wall. The fluids circulate respectively in each of these enclosures at different temperatures, a heat exchange being obtained through the common walls.
  • These exchangers generally consist of two joined tubes, one used for the circulation of the drawing water, and the other for the circulation of the heating water. These tubes pass through a bundle of fins and are located at the top of a combustion chamber.
  • the invention provides a heat exchanger made from two sheets each having corrugations and fixed for example by welding on both sides a common intermediate wall for the formation of two independent water circuits.
  • the pitch of the corrugations of one of the sheets is less than the pitch of the corrugations of the other sheet so as to multiply the points of contact with the intermediate partition.
  • the number of tubes constituting the domestic water circuit is greater than the number of tubes forming the heating water circuit.
  • FIGS. 1 and 2 show a heat exchanger with three fluids, one gaseous and the other two liquids.
  • This exchanger is produced by fixing on each side of an intermediate common wall 2, two sheets 10 and 20 comprising longitudinal corrugations 11 and 21, to obtain an exchanger plate designated as a whole by the reference 1.
  • the corrugations 11 form with the wall 2, a first network of tubes 12 for circulation of sanitary water L 1 and the corrugations 21 also form, with wall 2, a second independent network of tubes 22 for circulation of heating water L 2 .
  • the formation of the two networks of tubes 12 and 22 is carried out for example in the following manner: three flat sheets made of aluminum alloy or alloy are partially welded together and face to face stainless, and leaving strips not welded. The sheets thus assembled are then formed by directly exerting hydraulic pressure with the aid of water injected therebetween at the non-welded locations, the longitudinal corrugations 11 and 21 are thus obtained.
  • This product known per se, is particularly suitable for placing implementing the present invention, but it goes without saying that the undulations can be produced in any other way without departing from the scope of the invention.
  • the entire exchanger is made by superimposing at a distance from each other several plates 1 thus obtained so that the gases G which are for example the combustion gases of a burner gas flow between these plates as indicated by the arrows.
  • a plate 1 Starting from a plate 1, it is also possible to form a spiral exchanger inside which the hot gases circulate or else an exchanger of generally parallelepiped shape in which the hot gases are brought to carry out a particular path along said plate.
  • the pitch of the corrugations 11 of the sheet 10 is less than the pitch of the corrugations 21 of the sheet 20 which makes it possible to multiply the contact strips 13 between the sheet 10 and the intermediate wall 2 so increase the active heat exchange surface.
  • the two sheets 10 and 20 play the role of gas-water exchanger and the intermediate wall 2 forms a water-water heat exchange fin.
  • the hot gases G heat the two sheets 10 and 20 and the heat transfer fluids L 1 and L 2 .
  • the fluid L 1 is static and the fluid L 2 dynamic
  • the calories coming from the sheet 10 are transferred to the intermediate wall 2 given the high number of contact strips 13 and are added to the fluid L 2 .
  • water being a very poor thermal conductor the calories of the fluid L 2 in movement, are brought back to the common intermediate wall 2 because the fluid L 1 not being in circulation insulating form which makes it possible to increase the fluid temperature L 2 .
  • the diameter of the tubes 12 and 22 being relatively small, the water layers thus created are thin which increases the speed of circulation of the two fluids for a given flow rate and consequently facilitates heat exchanges.
  • This arrangement therefore makes it possible to obtain an extremely efficient exchanger even in the case where one of the fluids is not in motion.
  • longitudinal fins 3 can be attached to the contact strips 13 between each corrugation 11 of the sheet 10 in order to further increase the thermal conductivity of the assembly.
  • the intermediate plate 2 may include raised patterns to bring the calories from one circuit to the other.
