Definitions

  • the invention relates to a finned tube heat exchanger with side wall profile and support profile, especially for use as a condenser and dry cooler, with a housing made of side wall profiles, End walls and fans supporting elements that form a heat exchanger block enclose, at least consisting of heat exchanger tubes and carried by them Fins or cooling fins.
  • cooling fins have dovetail-shaped, aligned ones on the side edges Cutouts that form a kind of continuous groove in the heat exchanger block into which Intervene fasteners for the side wall profiles (DE-OS 24 18 132).
  • the object of the invention is now to design and build the finned tube heat exchanger to further improve the type mentioned and in particular to make it more cost-effective.
  • the side wall profiles act as the heat exchanger block load-bearing, one-piece, continuous elements are formed and further functional elements, in particular cable ducts, fan plate support elements, inspection openings, Have support frame profile body and air guide devices and that to hold the heat exchanger fins or cooling fins together with the heat exchanger pipes the heat exchanger block or several such form blocks connected in series, serve support profiles, which the slats or Include cooling fins on the end face and are mounted in the side wall profiles.
  • Such sidewall profiles can be and will be extruded profiles or rolled profiles usually made from one piece, but can be made from several over and / or arranged one behind the other and welded, screwed or riveted together or otherwise consist of related pieces.
  • the multiple function of these side wall profiles allows the fulfillment of numerous purposes, usually separate components have been reserved, which have so far been integrated into such side wall profiles had.
  • the one-piece design of the side wall profiles including more diverse Configurations, adapted to the different usage requirements leads to a substantial cost savings, with the relevant profiling of the side wall profiles in addition, for example by grooves, U-profiles and angle profiles in Appearance can occur, the rigidity and strength of the heat exchanger outer walls causes that is necessary to accommodate the weight of the heat exchanger block.
  • the side wall profiles can also be shaped in the lower area so that they simultaneously serve as air guiding devices and the heat exchanger feet or cross struts be able to record.
  • the support profiles can be plastic bodies be and have a U-shape, the two side legs of the long sides of the Grasp the heat exchanger block or the end faces of the fins, on the central web of the U-shaped support profile is expediently formed a rib which in a engages groove-shaped recess of the side wall profile.
  • the finned tube heat exchanger shown in Fig. 1 which is used in particular as a condenser or cooler is used, has a housing 1 consisting of two opposite, parallel side wall profiles 2, which are constructed essentially identically as well as end walls and plates 6 on the housing roof side. These parts enclose a heat exchanger block 3 or more such series connected Blocks essentially consisting of heat exchanger tubes 19 and carried by them Fins 16 or cooling fins.
  • the side wall profiles 2, which can be up to about 15 m long, are extruded profiles or rolled profiles and designed to hold the heat exchanger block 3 or more such blocks, continuous elements 4 form and more Functional elements, in particular cable channels 5, the fans 26 on plates or plates 6 supporting elements 30, inspection openings 7 and support frame body 8 which the feet 28 and the cross member 27 of the heat exchanger housing 1 are attached.
  • the side wall profiles 2 are in shape with parallel guide rails 23, 24 of material doublings and bevels 11 for their stiffening and air sealing provided, as shown in Fig. 3, wherein the guide rails and bevels Take up and guide heat exchanger block 3, its weight over the side wall profiles 2 and their base-side support frame body 8 and cross member 27 transferred to the feet 28 becomes.
  • Foreclosure means the laying of possible bypass air flows Optimization of the flow of the intake air through the heat exchanger block.
  • the side wall profiles 2 are formed in one piece in the longitudinal direction, i.e. in the rolling or Extrusion process made in one piece, but there is also the possibility if necessary, cut these sections up to 15 m long into several sections divide and then assemble, for example to weld together rivet or screw.
  • the one end 12 of the heat exchanger housing 1 shows the or the side wall profiles 2, which also have a height or width can consist of several parts, beyond the end of the heat exchanger block 3.
  • the housing 1 is covered by cover plates 13 shown in FIG. 1 and over the housing width extending compensating or cover plates 29, which are also from the Sidewall profiles 2 or their fan plate support elements 30 are added, closed, behind the cover plates inside the heat exchanger housing 1 the collectors 14 are located.
  • the finned tube heat exchanger described above is one of the features in that it has the heat exchanger block 3 supporting side wall profiles 2, which as one-piece and not multi-piece bodies are formed in the length and not just one Support function, but multiple other functions of the type described above fulfill what is necessary both for the production of such apparatus and their maintenance significant cost savings as well as significant simplifications that the Enabling the construction and assembly of such apparatus in the form of a modular system.
  • Support profiles 15 in serve to receive the heat exchanger fins 16 or cooling fins Connection with the bevels 11 which engage around the end of the fins 16 or cooling fins and are mounted in the side wall profiles 2 in a fixed or longitudinally displaceable manner.
  • the support profiles 15, of which Figures 5 to 7 are further possible Embodiments show, for example as a plastic body and have a U-shaped cross section, the two side legs 17, 18 of the long sides of the Grasp heat exchanger blocks 3 or the end faces of fins 16.
  • the rib 21 is chamfered at its ends.
  • the two parallel bevels lie the corresponding bevels 11 delimiting the longitudinal groove 22 in the side wall profile 2 between the two guide rails 23, 24 opposite, so that the support profile 15 with the help of the rib 21 between the guide rails 23, 24 in the longitudinal groove 22 a has defined sliding fit, the lower guide rail 24 being the weight of the heat exchanger block 3 receiving support body is formed and the two guide rails as part of the side wall profile 2 extend parallel to the longitudinal groove 22.
  • the guide rails 23, 24 are also used for air separation and prevent the suction Air in the bypass flows past the heat exchanger block 3.
  • the heat exchanger block 3 can be outside of the heat exchanger housing 1 easy to assemble and then as a unit by the two side support profiles 15 is limited, insert into the housing or the grooves 22 provided for this purpose.
  • the configuration of the support profile 15 is accessible to further modifications, such as, for example shown in Figures 4-8, in particular to the design of the side wall profile 2 adjust and ensure that the fins 16 or cooling fins lie within the support profile.
  • the support profiles 15 can also be designed entirely or partially as a hollow body 38, as can be seen in FIGS. 6-8 and on their side wall profile 2 Surface be provided with recesses 40, 41, in the lugs or ribs or cone-shaped Interfering features 39, 42 of the side wall profile 2.
  • the support profiles can also be designed or shaped that they snap into the side wall profiles 2, clamp or snap into place.
  • the hollow chamber profiles for the support profiles essentially serve to increase stability and weight reduction and also have the advantage of saving material.
  • each support profile 15 can be supported by mounting plates 31 hold on to the heat exchanger block 3 additionally or exclusively.
  • Bracket plates one of which is shown in Fig. 4, are convenient angled and have a one-part or multi-part longitudinal leg 33 and a cross leg 35 arranged approximately at right angles to this. The latter leaves insert into a slot 32 of the support profile or on the respective end face of the Place the support profile as shown in Fig. 5.
  • the cross leg 35 is provided with bores 36 for receiving heat exchanger tubes 37 and / or support rods and the like. provided, as can be seen from Fig. 5.
  • the parts mentioned reach through the fins or cooling fins of the heat exchanger block 3 and thereby a fixed connection between the support profile 15 and the heat exchanger block 3.
  • the bending should prevent the heat exchanger block 3 if the fins are not themselves accordingly are structured.
