Definitions

  • the subject-matter of this invention consists of a heat exchanger particularly well-suited for use in recovering heat from wet gasses.
  • the exchanger according to the invention is particularly well-suited for use in boilers for domestic heating purposes : in this case the heat is recovered from the fumes, in the form of sensitive heat and latent heat, at temperature levels at which in traditional boilers it is normally lost.
  • the heat exchanger according to the invention consists of a series of pressed metal plates, having a limited thickness, clamped against one another by means of stay-bolts, and equipped with a pair of end openings. Once the series of plates forming the exchanger has been assembled, the openings are aligned and form the two distribution and collection headers of the water to be heated, and which forms the secondary fluid.
  • Each plate is lapped on one side by the primary fluid (wet gasses) and on the other side by the secondary fluid (water to be heated).
  • Each pair of adjacent plates is separated by suitable spacers which allow the formation of a meatus through which one or the other of the fluids passes.
  • each pair of adjacent plates defining the meatus for the passage of the fumes are separated from one another by suitable spacers and by a pair of circular gaskets located around the above mentioned openings.
  • the two opposing faces of the subsequent pair of adjacent plates are, on the other hand, separated by gaskets which follow the perimeter of the plates so as to form a sealed compartment which communicates only with the two headers formed by the succession of the openings mentioned above.
  • Each plate is suitably equipped with V shaped grooves, positioned diagonally.
  • V shaped grooves of one plate are crossed with those of the next plate, so as to favour the turbulence of the fluids which come into contact with these plates.
  • the heat exchanger according to the invention is formed by a series of adjacent plates 10 made by pressing thin metal sheeting.
  • the exchanger is also equipped with two very thick and stiff end-plates 20.
  • the series of pressed metal plates 10 and two end-plates 20 is held together by four stay-bolts 24 which pass through corresponding holes 13 and 23 made respectively in the printed metal plates 10 and in the two end-plates 20.
  • Each printed metal plate 10 has an approximately rectangular shape, and near to its two short sides it has two large holes 11 and 12, which serve as openings for the passage of the water to be heated.
  • Each of the two end plates 20 is fitted with one further hole only, numbered respectively 21 and 22, located in positions corresponding to holes 11 and 12 respectively of the pressed metal plates 10.
  • Each printed metal plate 10 has a continuous impression 30, with a practically V shaped transverse cross- section, which surrounds uninterruptedly both the two holes 11 and 12 and the outer contour of the plates 10.
  • This impression 30 is therefore formed by a pair of circular impressions 31 surrounding the two holes 11 and 12 and two elongated impressions 32 which join said two circular impressions 31.
  • the impression 30 gives rise to a rib on one face of the plate, and to a corresponding groove on the other face : the impression 30 is of course obtained by pressing.
  • the impressions are all made to face in the same direction, as shown in figure 3, so that the impressions of adjacent plates fit partly into one another.
  • the impressions 31 are made so that circular gaskets 41 fit into them, gaskets which create between the openings 11 and 12, the headers through which the water to be heated passes.
  • These circular gaskets 41 are alternately positioned between pairs of adjacent plates 10 : that is to ' say between the first and second, between the third and fourth, between the fifth and sixth plates and so on. More closed gaskets 42 occupy the impressions 32 and the outer edge of the impressions 31, following approximately the contours of the plates 10.
  • gaskets 42 are alternated with the gaskets 41 and are therefore positioned between the second and third, between the fourth and fifth plates and so on, as shown in figures 1 and 3.
  • the water passing through the openings 11 and 12 is free to circulate between the pairs of plates 10 separated instead by the perimetrical gaskets 42.
  • spacers may be made in different ways. According to the form of embodiment illustrated in figure 1, same may consist of thin metal wires 53 bent into coils. According to the form of embodiment illustrated in figure 3 and in figures 9 to 12, these spacers may consist of transverse impressions 54, positioned alternately on the plates 10.
