Definitions

  • the invention relates to mixed hot water boilers, that is to say boilers intended to heat water to supply both a central heating circuit and a sanitary or hot water drawing circuit.
  • the invention also relates to the double pipes of said boilers and more particularly their rectilinear segments.
  • the invention aims, among other things, to remedy these drawbacks.
  • the rectilinear segments of the double pipes of the kind in question according to the invention comprising two sections of metal pipe juxtaposed laterally, are essentially characterized in that at least one of these two sections is delimited, on its most distant from the other section, by a metal strip whose two longitudinal edges are curved and are welded against the longitudinal edges of an intermediate metal partition also forming part of the segment considered and in that this intermediate partition has stamped bosses whose vertices are in contact with the blade and are secured to it.
  • the invention also relates to heat exchangers comprising pipes as defined above as well as boilers equipped with such exchangers.
  • the invention comprises, apart from these arrangements high to melt said material at the vertices 6.
  • each rectilinear segment composed of two adjoining sections A and B is ultimately delimited by two parallel flat portions connected to each other by two curved portions of semi-circular section: the cross section of this segment is basically writable in an elongated rectangle whose width is generally between 40 and 100 mm, being generally of the order of 60 mm.
  • the bosses 5 are advantageously in the form of rounded nipples whose base is oval and elongated in the longitudinal direction of the tuber, the major axis of the oval being of the order of 8 mm and its small axis, of the order of 4 mm and the longitudinal gap reserved between the successive bosses being of the order of 8 mm.
  • the longitudinal ends of these rectilinear segments are advantageously arranged in the following manner (see FIGS. 3 and 4).
  • Each longitudinal end of the intermediate partition 4 is deformed transversely along an S so as to reveal two longitudinal half-cups 11, 12 open longitudinally towards the outside and projecting respectively on the two opposite faces of the partition.
  • each half-bucket is equal to the thickness of a section (A, B) so that its bottom is juxtaposed contiguously against the blade (1, 7) opposite.
  • Each dem-bucket 11, 12 is separated from the adjacent longitudinal edge of the partition 4 by a flat, non-deformed narrow margin (15, 16) of this partition.
  • each longitudinal end of the blade is deformed so as to reveal there a longitudinal half-bucket 14 smaller than the previous ones, also open longitudinally towards the outside and the depth of which is such that its bottom is juxtaposed. joined against the trigger guard 13.
  • the portions of walls in mutual contact are advantageously shuffled against one another.
  • the neck 17 serving the only section A (fig. 3 and 4) is delimited by the half-bucket 11 and the facing portion of the blade 1, this neck being closed, on the side of the longitudinal edge of the segment considered, by welding the curved edge 2 against the margin 15, and on the middle side of the height of said segment, by applying the bottom of the corresponding half-bucket 14 against the trigger guard 13.
  • the numbers of the bosses 5 projecting respectively from the two faces of the partition 4 are identical so that the turbulence imposed on the water currents flowing respectively in the two sections A and B is the same.
  • the numbers of these bosses projecting respectively on either side of the partition 4 are given different values, this number being higher for the section A in which the heating water circulates as in the section B in which the drawing water circulates.
  • the Applicant has in fact observed that the risk of scaling is higher than in the second circuit than in the first since, in the first case, the heating water circulates in a closed circuit and therefore carries a proportion of charges mineral weaker and weaker as it circulates.
  • bosses represented in spectrum is equal to twice the number of the bosses projecting in the section B and shown in solid line.
  • the necks 17 above assigned to the heating circuit are given a larger section than that of the necks 18 assigned to the drawing-off circuit.
