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.

Claims (4)

1. Wärmetauscherelement (1), das aus Rohren (10) besteht, in denen ein Fluid umläuft und in dem die Rohre Schleifen bilden, die in der Ebene des Wärmetauschers angeordnet sind und Krümungen und untereinander parallele senkrechte Abschnitte (11) bilden, wobei mindestens ein Rohr, das eine zusätzliche Halbschleife (12, 14) bildet, aus der Ebene des Wärmetauschers austritt und die senkrechten Abschnitte (11) umgürtet und eine Befestigung der Schleifen bildet, dadurch gekennzeichnet, daß ein Flachprofil (2) in Höhe der zusätzlichen Halbschleife eingesetzt wird, wobei dieses Flachprofil mit halbkreisförmigen öffnungen versehen ist, die je einen senkrechten Abschnitt aufnehmen, wobei das die zusätzliche Halbschleife bildende Rohr verlängert ist, um eine ganze Schleife (12) zu bilden, die das Wärmetauscherelement ohne Unterbrechung des Fluidkreislaufs umgibt.
2. Wärmetauscherelement nach Anspruch 1, dadurch gekennzeichnet, daß es mindestens eine Klampe (3) aufweist, die auf irgendeinen der senkrechten Abschnitte aufgeschweißt ist.
3. Wärmetauscherelement nach einem der Ansprüche 1 oder 2, dadurch gekennzeichnet, daß zwei Abschnitte zwei Bögen (13) bilden, die die zusätzliche Schleife (12) umgeben, um sie in Kontakt mit den anderen senkrechten Abschnitten (11) zu halten.
4. Wärmetauscherelement nach einem der Ansprüche 1, 2 oder 3, dadurch gekennzeichnet, daß die beiden nebeneinanderliegenden senkrechten Abschnitte (114, 115) einen Ring (15) ohne Unterbrechung des Fluidkreislaufs zwischen diesen beiden Abschnitten bilden, wobei dieser Ring eine zusätzliche Schleife trägt, die aus zwei Halbschleifen (14A, 14B) gebildet wird, welche sich je auf einer Seite der senkrechten Abschnitte abstützen.
