Abstract

The inlet and outlet manifolds (4) are situated outside of the casing (1) and have a demountable character, such that by removing said manifolds (4), "in situ" cleaning and maintenance tasks of the tubular battery are possible, as well as the temporary closing off of any of said tubes (3) which is broken down, by closing the ends (10) thereof by means of respective caps, and the extraction of the broken down tubes, for the replacement thereof, through the side opposite to the manifolds (4) is also possible after the unwelding of the two connections and as a result of the existence of special crossbars (13-14) which, suitably fixing the tubes (13) inside the framework (16), are shaped and positioned so as to not constitute stops interfering in said transverse shifting of the tubes.

Realización preferente de la invenciónPreferred Embodiment of the Invention

A la vista de las figuras reseñadas puede observarse como la batería tubular para torres de refrigeración que la invención propone está constituida, como cualquier batería convencional, a partir de una carcasa de cerramiento (1), de cualquier tipo convencional, ya sea de polkster o metálica, en cuyo seno (2) se establecen una pluralidad de tubos (3) de intercambio térmico, convenientemente protegidos exteriormente, que configuran a modo de serpentines, y más concretamente planos tubulares en los que dichos tubos están asistidos por colectores de entrada y salida de fluido.In view of the figures outlined you can be seen as the tubular battery for cooling towers that the invention proposes is constituted, like any battery conventional, from a enclosure housing (1), of any conventional type, either of polkster or metallic, in whose sinus (2) a plurality of exchange tubes (3) are established thermal, conveniently protected externally, that make up by way of coils, and more specifically tubular planes in the that said tubes are assisted by inlet and outlet manifolds of fluid

Pues bien, de acuerdo ya con la invención los citados colectores (4) se sitúan por fuera de la carcasa (1) y se montan sobre esta última embridados y desmontables. De forma más concreta cada colector (4) se estructura mediante dos piezas (4-4'), de las que la pieza (4) es la que resulta exterior a la carcasa (1) y se prolonga en la correspondiente acometida (5), mientras que la pieza (4') se solidariza a la carcasa (1) en una abertura operativamente practicada en esta última, y cuenta con orificios roscados (6) para fijación, con la colaboración de tornillos (7) y con interposición de una junta (8), de la pieza exterior (4) del colector, como se observa especialmente en la figura 3.Well, according to the invention, the said manifolds (4) are located outside the housing (1) and are mounted on the latter flanged and removable. More concrete each collector (4) is structured by two pieces (4-4 '), from which the piece (4) is the result outside the housing (1) and extends in the corresponding rush (5), while the piece (4 ') is in solidarity with the housing (1) in an opening operatively practiced in this last, and has threaded holes (6) for fixing, with the screw collaboration (7) and with interposition of a joint (8), of the outer part (4) of the collector, as observed especially  in figure 3.

La pieza interior (4') es atravesada por los tubos (3) que emergen sustancialmente hacia el interior del colector y que se fijan mediante cordones de soldadura (9), de manera que ante una eventual avería en uno de dichos tubos (3) éste puede ser inutilizado temporalmente retirando la brida exterior (4) y obturándolo con tapones acoplables en sus extremos o embocaduras (10), pudiendo posteriormente dicho tubo dañado (3) ser sustituido, mediante extracción del mismo por el lateral (11) de la carcasa (1) opuesto a los colectores (4), liberando de la pieza interna (4') mediante corte y desoldado del tubo (3) en su sector extremo y sobresaliente con respecto a la pieza (4').The inner piece (4 ') is crossed by the tubes (3) that emerge substantially into the interior of the manifold and that are fixed by welding cords (9), of so that in case of a possible breakdown in one of said tubes (3) this can be temporarily disabled by removing the outer flange (4) and securing it with attachable plugs at its ends or openings (10), subsequently said damaged tube (3) being able to be replaced, by removing it from the side (11) of the housing (1) opposite to the collectors (4), releasing from the internal part (4 ') by cutting and desoldering of the tube (3) in its extreme sector and outstanding with respect to the piece (4 ').

Para estabilizar convenientemente los tubos (3) en el interior de la armadura (16), sin que los medios de apoyo de los mismos interfieran ante su posible necesidad de extracción, se ha previsto para la utilización de las traviesas (13) y (14) representadas en detalle en la figura 4, contando las traviesas (13) con cortos brazos radiales (15) orientados en un mismo sentido, y las traviesas (14) con brazos (15) radiales y contrapuestos, destinados a hacer tope sobre los tubos (3), utilizándose en cada caso aquellas traviesas que resulten más idóneas, como se desprende de la observación de la figura 2.To conveniently stabilize the tubes (3) inside the armor (16), without the support means of they interfere with their possible need for extraction, they has planned for the use of sleepers (13) and (14) represented in detail in figure 4, counting the sleepers (13) with short radial arms (15) oriented in the same direction, and the sleepers (14) with radial and opposite arms (15), intended to stop on the tubes (3), being used in each case those sleepers that are more suitable, as follows from the observation in figure 2.
