Definitions

  • the present invention relates to a heat exchanger element consisting of tubes in which a fluid circulates and in which the tubes form loops located in the plane of the exchanger and formed by elbows and vertical sections parallel to each other, at least a tube forming an additional semi-loop leaving the plane of the exchanger element and encircling the vertical sections and creating a joining of the loops.
  • the document EP-A-0 143 432 describes a panel of horizontal tubes sandwiched between pairs of vertical tubes provided on their sides facing half-fins with notches of circular shape. It requires that the half-fins are welded to the vertical tubes, then cut them according to a very precise profile, so that the manufacturing cost of the panel is relatively high.
  • GB-A-942036 describes a panel of horizontal heat exchange tubes in a vertical plane, comprising an additional loop enclosing the tubes of the panel.
  • the tubes of the panel are not kept in fixed relative positions, so that they can still vibrate or undergo deformations as a result of differential expansions.
  • the present invention aims to provide a device for securing the loops of a heat exchange element which ensures the maintenance of the tubes relative to each other in substantially fixed relative positions, while being of low cost Manufacturing.
  • the heat exchanger element of the invention is characterized in that a scalloped dish is installed at the level of the additional semi-loop, this dish being provided with semicircular openings each receiving a vertical section, the tube forming the additional semi-loop being extended so as to form a complete loop surrounding the exchanger element without discontinuity in the circulation of the fluid.
  • Two sections form two crunches enclosing the additional loop to keep it resting on the other vertical sections.
  • the two adjacent vertical sections form a ring without discontinuity in the circulation of fluid between these two sections, this ring supporting an additional loop consisting of two half-loops each resting on one side of the vertical sections.
  • Figure 1 shows that the exchanger element consists of at least one tube 10 in which a fluid continuously flows between an outlet and an inlet not shown.
  • This tube has multiple loops formed of elbows and vertical sections 11, these sections being mutually parallel and located in the plane of the exchanger element.
  • This FIG. 1 shows an additional loop 12, better visible in FIG. 2, which encloses the sections 11, and a loop 14 surrounding the sections 11 consisting of two half-loops, these two half-loops being better visible in FIG. 5.
  • FIG. 1 also shows the location of a support cleat 3, this cleat being represented in FIG. 4.
  • FIG. 2 In Figure 2 are shown, in section, the vertical sections 11, surrounded by the additional loop 12.
  • a scalloped dish 2 provided with semicircular openings each receiving a section 11, is installed at the additional loop. This indented dish ensures the equidistance of the sections and contributes, with the additional loop, to the rigidity of the element.
  • the additional loop 12 leaves a section 110, goes around the sections by surrounding them, and returns to the starting point to reconstruct the section 110.
  • This loop 12 is supported by two bosses 13 each formed from a section 111 and 112, this being better visible in FIG. 3.
  • FIG. 3 a view in section along III of FIG. 2, shows the additional loop 12, the indented dish 2, the bosses 13.
  • FIG. 4 In FIG. 4 are shown two tabs 3 welded on a section 11, these tabs being placed along an additional loop 12 to support the latter, as can be seen in FIG. 1.
  • the half-loop 14A is formed without discontinuity in circulation, between the two end sections 11, and the half-loop 14B is formed, without discontinuity in circulation of fluid, between the two penultimate end sections.
  • These two half-loops 14A, 14B are held by a ring 15 produced at the end of two adjacent vertical sections 114, 115, this ring being clearly visible in FIG. 6.
