Definitions

  • the present invention refers a tubular heat exchange battery, of those used in evaporative cooling equipment, and more specifically in closed circuit evaporative cooling towers.
  • each one of the coil-shaped tubes forming the tubular heat exchange battery for closed circuit evaporative cooling towers be easily extractible from inside the framework in the worksite of the cooling tower, enabling its "in situ" replacement and repair due to the new fixing elements of the tubes on the inside thereof, and to the external character of the manifolds.
  • liquid inlet and outlet manifolds are flange-mounted and are easily demountable for enabling the inspection, internal cleaning, sealing tests and individualized provisional closing off of each tubular plane in the event of breakdown, said manifolds furthermore being positioned outside of the enveloping casing of the tower to facilitate all the more said operations.
  • tubular battery for closed circuit evaporative cooling towers proposed by the invention, based on the moderate working pressure it must support, implies a new concept structured in order to solve the drawbacks set forth above.
  • the tubular heat exchange battery for closed circuit evaporative cooling towers object of the invention allows the individualized extraction of the unusable tubular planes due to the design of the framework, which is provided with special crossbars, each tubular plane being formed by a coil tube. Said extraction can be carried out without needing to move the battery from its location.
  • the battery is no longer irreparable, allowing the temporary, fast and individualized closing off of the damaged tubular planes, as well as the possible replacement of said extractible planes, and replaced from the open rear portion of the framework.
  • the battery object of the present invention likewise enables the inspection, internal cleaning and individualized performance of watertightness tests for each tubular plane without needing to move or break the battery as a result of the introduction of demountable manifolds flanged to the enveloping casing containing the framework and located at the liquid inlet and outlet, and not included in the framework body.
  • the battery is no longer mono-block and airtight.
  • the battery is no longer inaccessible, linking the design to a system for the easy opening of the opposite part of said framework and casing, leaving all the tubular planes uncovered.
  • tubular heat exchange battery for closed circuit evaporative cooling towers proposed by the invention is constituted, like any conventional battery, of an enclosure casing 1, of either polyester, metal or the like,, in the cavity 2 of which a plurality of heat exchange tubes 3 are arranged, duly protected externally by means of a framework 16, which are shaped as coils and more specifically tubular planes, wherein said tubes 3 include fluid inlet and outlet manifolds 4.
  • each manifold 4 is structured by means of two parts 4-4', of which parts part 4 is the one outside the casing 1 and extending into the corresponding inlet 5, whereas part 4' is joined to the casing 1 at an opening operatively made on the latter and has threaded holes 6 for fixing, with the cooperation of screws 7 and the placing of a seal 8, of the outer part 4 of the manifold, as especially seen in Figure 3.
  • the inner part 4' is traversed by the tubes 3 substantially projecting towards the inside of the manifold and which are fixed by means of weld beads 9, such that in the event of a possible breakdown in one of said tubes 3, the latter can be temporarily disabled by removing the outer flange 4 and blocking it with caps that can be coupled at its ends or entrances 10, said damaged tube 3 being able to be subsequently replaced by means of the extraction thereof through the side 11 of the casing 1 opposite to the manifolds 4, releasing it from the inner part 4' by means of cutting and unwelding the tube 3 in its end sector projecting with regard to part 4'.
  • crossbars 13, 14 fixed to the frame, and preferably horizontal and perpendicular to the coil shaped tubes 3, has been provided for.
  • Said crossbars 13 have short radial arms 15, oriented in the same direction, and the crossbars 14 have opposing radial arms 15, intended for acting as stops for the tubes 3, those crossbars which are most suitable in each case according to the span of the coil shaped tube they must support being used, as can be inferred from observing Figure 2.
  • said crossbars 13, 14 and radial arms 15 will not constitute stops preventing the transverse shifting of said tubes 3 within their own plane during the operation for the extraction thereof.
  • Said crossbars 13, 14 have a double function, such as, as previously mentioned, allowing the individualized extraction of the different coil shaped tubes 3 constituting the heat exchange battery, and in turn preventing the movement of the tubes 3 inside the framework 16 of the battery during the galvanizing process. Said movement of the tubes 3 inside the zinc bath is prevented since the transverse and perpendicular arrangement of the crossbars 13, 14 in relation to the tubes prevents the vertical movement inside the zinc bath thereof, whereas the radial arms 15 prevent the horizontal movement of said tubes 3 inside the framework 16.
  • Said framework 16 comprises the tubes 3 on the inside thereof, the framework being formed by an outer structure, preferably of steel, and horizontally traversed by the crossbars 13, 14 joined to the framework 16 and which support the coil shaped tubes 3. Likewise, the rear portion of said framework 16 is provided with a certain number of removable flat bars which, after being removed, allow for the individual extraction of the tubes 3.
