Abstract

The plate type heat exchanger has air in the tubes and water on the outside. Each plate consists of two outside plates separated by ribs (3) to form parallel passages of square section between the outside plates. The plates are in banks connected in parallel to form a block. The blocks may be assembled to form a hollow square with air flowing horizontally towards the centre and upwards under the action of a fan. Water flows from the top to the bottom into a reservoir.

Description

La présente invention concerne les dispositifs d'échange de chaleur entre un liquide et un gaz et, plus particulièrement, les dispositifs utilisés pour refroidir de l'eau au moyen de l'air atmosphérique et que l'on appelle naéroréfrigérants,
Les aéroréfrigérants les plus couramment utilisés sont du type "humide". Ils comportent en genéral une cheminée, à tirage naturel ou forcé, à la base de laquelle sont installés des dispositifs de dispersion qui comportent des surfaces sur lesquelles l'eau à refroidir ruisselle et devant lesquelles passe l'air aspiré Par la cheminée.The present invention relates to heat exchange devices between a liquid and a gas and, more particularly, devices used to cool water by means of atmospheric air and which are called water coolers,
The most commonly used air coolers are of the "wet" type. They generally comprise a chimney, with natural or forced draft, at the base of which are installed dispersing devices which comprise surfaces on which the water to be cooled streams and in front of which the air sucked in passes through the chimney.

Un inconvénient de tels appareils réside en ce que, souvent, il sort de la cheminée un panache de vapeur d'eau en cours de condensation, analogue, quant à son aspect et à sa constitution physique, à un nuage ou à un brouillard dense. A drawback of such devices lies in the fact that often a plume of water vapor in the process of condensation leaves the chimney, analogous, as regards its appearance and its physical constitution, to a dense cloud or fog.

Afin de réduire ce panache, on a proposé d'équiper un aéroréfrigérant non seulement de dispo$itifs de dispersion du genre précité mais aussi de dispositifs d'échange du type dit "sec" dans lesquele l'eau à refroidir circule dans des tubes à ailettes, sans contact avec l'air extérieur, ce qui permet d'abaisser la teneur en humidité de l'air qui sort de la cheminée. Une telle solution présente l'inconvénient d'augmenter la complexité du circuit d'eau et de ne pas conduire à un écoulement homogène de ltair.  In order to reduce this plume, it has been proposed to equip an air cooler not only with dispersion devices of the aforementioned type but also with exchange devices of the so-called "dry" type in which the water to be cooled circulates in tubes with fins, without contact with outside air, which lowers the moisture content of the air coming out of the chimney. Such a solution has the drawback of increasing the complexity of the water circuit and of not leading to a homogeneous flow of air.

La présente invention a pour but essentiel de perfectionner les dispositifs d'échange de chaleur entre liquides et gaz et, notamment, les aéroréfrigérants, en permettant de cumuler les avantages des appareils des types sec et humide tout en évitant, dans la mesure du possible, leurs inconvénients. The main object of the present invention is to improve the heat exchange devices between liquids and gases and, in particular, air coolers, by making it possible to combine the advantages of dry and wet type devices while avoiding, as far as possible, their disadvantages.

A cet effet, selon l'inventionw Qaon équipe l'échangeur de dispositifs de dispersion dont les éléments sont creux et on fait Passer le gaz non seulement devant les surfaces desdits éléments sur lesquelles ruisselle le liquide, mais aussi dans les éléments eux-mêmes. Ces éléments sont donc utilisés de deux façons : à l'extérieur, comme surfaces de dispersion et de ruissellement pour 11 eau ou autre liquide à refroidir et, à l'intérieur, comme des tubes d'échange de chaleur parcourus par du gaz, par exemple de 11 air, sec.  To this end, according to the invention, Qaon equips the exchanger with dispersing devices, the elements of which are hollow and the gas is passed not only in front of the surfaces of said elements over which the liquid flows, but also in the elements themselves. These elements are therefore used in two ways: outside, as dispersing and trickling surfaces for water or other liquid to be cooled and, inside, as heat exchange tubes traversed by gas, by example of 11 air, dry.

On obtient ainsi, à la sortie du dispositif d'échange dont la structure demeure très simple, un mélange intime d'air sec et humide dont la teneur globale en humidité peut titre aisément réglée, notamment de façon à éviter le panache. There is thus obtained, at the outlet of the exchange device, the structure of which remains very simple, an intimate mixture of dry and humid air whose overall moisture content can easily be adjusted, in particular so as to avoid the plume.

Cette combinaison de dispositifs secs et humides est donc très intéressante. This combination of dry and wet devices is therefore very interesting.

Ses principaux avantages sont les suivants
- supprimer le panache visible
- permettre d'utiliser des surfaces d'échange judicieusement
choisies faciles à fabriquer, par exemple par extrusion
- homogénéiser le flux d'air et assurer son bon mélange
- réduire le niveau de bruit en évitant la chute de gouttes
sur un plan d'eau
- simplifier la conception de la tour
- réduire les dimensions de la tour.Its main advantages are as follows
- remove the visible plume
- allow the use of exchange surfaces judiciously
chosen easy to manufacture, for example by extrusion
- homogenize the air flow and ensure its good mixing
- reduce the noise level by preventing drops from falling
on a body of water
- simplify the design of the tower
- reduce the dimensions of the tower.

La combinaison peut être utilisée sur la totalité de la hauteur du dispositif d'échange dune tour ou sur une partie seulement, le tirage étant réalisé soit par des ventilateurs, soit, de façon naturelle, par une cheminée. The combination can be used over the entire height of the exchange device of a tower or only a part, the draft being carried out either by fans or, naturally, by a chimney.

La description qui va suivre, en regard du dessin annexé, donné à titre d'exemple non limitatif, fera bien comprendre comment l'invention peut être réalisée, les particularités qui ressortent, tant du dessin que du texte, faisant, bien entendu, partie de ladite invention. The description which follows, with reference to the appended drawing, given by way of nonlimiting example, will make it clear how the invention can be implemented, the features which emerge, both from the drawing and from the text, of course forming part of said invention.

La figure 1 est un croquis schématique illustrant la ob de base et structure de base et le fonctionnement de la combinaison de l'invention. Figure 1 is a schematic sketch illustrating the basic ob and basic structure and the operation of the combination of the invention.

La figure 2 est une vue schématique en perspective et avec arrachement d'un aéroréfrigérant à tirage artificiel équipé selon l'invention.  Figure 2 is a schematic perspective view with cutaway of an artificial draft air cooler equipped according to the invention.

les figures 3, 4 et 5 sont des vues de détail montrant quelques exemples d'éléments tubulaires. Figures 3, 4 and 5 are detail views showing some examples of tubular elements.

La figure 6 est une vue schématique en perspective et avec arrachement d'un aéroréfrigérant à tirage naturel équipé selon l'invention d'éléments tubulaires ondulés. Figure 6 is a schematic perspective view with cutaway of a natural draft air cooler equipped according to the invention of corrugated tubular elements.

La figure 7 illustre en élévation et à plus grande échelle la disposition des éléments de la figure 6.  FIG. 7 illustrates in elevation and on a larger scale the arrangement of the elements of FIG. 6.

Sur le schéma de la figure 1, sont représentés deux éléments 1 d'un dispositif d'échange combiné selon l'inventione
Ces éléments sont constitués par des plaques parallélépipédiques creuses ouvertes à leurs extrémités et dont les grandes faces latérales 2 sont réunies par des cloisons 3 parallèles entre elles et aux faces latérales étroites 4 des éléments. Les cloisons 3 peuvent etre équidistantes, mais cela n'est pas obligatoire.In the diagram of FIG. 1, two elements 1 of a combined exchange device according to the invention are represented.
These elements consist of hollow parallelepipedic plates open at their ends and whose large lateral faces 2 are joined by partitions 3 which are parallel to each other and to the narrow lateral faces 4 of the elements. Partitions 3 can be equidistant, but this is not compulsory.

En service, les éléments 1 sont disposés verticalement à distance les uns des autres, de telle sorte que les canaux 5 ménagés par les cloisons 3 soient orientés dans la direction d'écoulement du gaz, par exemple de l'air. Un passage 6 est ménagé entre deux éléments voisins. Le liquide ruisselle le long des faces latérales 2 et à l'extérieur des éléments. In service, the elements 1 are arranged vertically at a distance from each other, so that the channels 5 formed by the partitions 3 are oriented in the direction of flow of the gas, for example air. A passage 6 is formed between two neighboring elements. The liquid flows along the side faces 2 and outside the elements.

Le gaz se divise en deux flux : l'un qui parcourt les canaux 5 et qui demeure sec et ltautreS qui emprunte les passages 6 et qui s'humidifie au contact du liquide qui ruisselle sur les éléments 1. L'application de la dynamique des fluides permet de régler la valeur de ces flux. Ces derniers s'unissent à la sortie du dispositif d' échange pour former un flux unique dont on peut régler à volonté la teneur en humidité. The gas is divided into two streams: one which runs through the channels 5 and which remains dry and the other which takes the passages 6 and which moistens on contact with the liquid which trickles over the elements 1. The application of the dynamics of fluids adjusts the value of these flows. The latter join at the outlet of the exchange device to form a single flow, the moisture content of which can be adjusted as desired.

Sur la figure 2, un aéroréfrigérant 7 comporte un dispo site! d'échange constitué d'éléments 1 disposés verticalement, à égales distances les rmns des autres et de telle sorte que leurs canaux soient horizontaux, entre un bassin supérieur 8 d'alimenta- tion en eau, muni de trous d'écoulement 9 destinés à laisser tomber l'eau sur les éléments 1 et un bassin inférieur 10 dans lequel viennent baigner les pieds desdits éléments. Le dispositif d'échange entoure une cheminée 91, dans le cas présent équipés d'un ventilateur t2 pour tirage artificiel. les canaux 5 et passages 6 s'ouvrent sur l'extSrieur et aboutissent à la cheminée 11.  In FIG. 2, an air cooler 7 has a site available! exchange consisting of elements 1 arranged vertically, at equal distances from each other and so that their channels are horizontal, between an upper basin 8 for water supply, provided with drainage holes 9 intended for drop the water on the elements 1 and a lower basin 10 in which the feet of said elements come to bathe. The exchange device surrounds a chimney 91, in this case equipped with a fan t2 for artificial draft. the channels 5 and passages 6 open onto the exterior and lead to the chimney 11.

La figure 3 montre un élément i dont les faces latérales 2 sont munies de nervures 13, transversales à la direction d'4eou- lement de l'eau et destinées à éviter que celle-ci, qui ruisselle le long desdites faces, ne se divise en courants séparés. On obtient ainsi une pellicule ou film de ruissellement régulière sur les éléments.  FIG. 3 shows an element i, the lateral faces 2 of which are provided with ribs 13, transverse to the direction of flow of the water and intended to prevent the latter, which flows along said faces, from dividing in separate currents. This gives a uniform film or film on the elements.

Selon la figure 4, l'élément 1 est formé de deux plaques identiques 14 munies de nervures 15 en équerre parallèles entre elles et que l'on assemble tête-beche de façon à obtenir les canaux 5. 1a face externe des plaques 14 peut être striée, comme dans l'exemple précédent. According to FIG. 4, the element 1 is formed from two identical plates 14 provided with ribs 15 at right angles to each other and which are assembled head-to-head so as to obtain the channels 5. The external face of the plates 14 can be striated, as in the previous example.

La figure 5 montre des éléments 1, qui comportent une série de canaux 5 à section droite circulaire, accolés, flanquée en haut et en bas de brides 16 de raccordement convenablement décalées sur le côté et qui permettent de réunir le nombre voulu d'éléments pour former le dispositif d'échange. Les faces externes 17 des éléments sont munies d'ondulations jouant le meme role que les stries 13 décrites en regard de la figure 3. FIG. 5 shows elements 1, which comprise a series of channels 5 of circular cross section, joined together, flanked at the top and bottom of connection flanges 16 suitably offset on the side and which make it possible to assemble the desired number of elements for form the exchange device. The external faces 17 of the elements are provided with corrugations playing the same role as the ridges 13 described with regard to FIG. 3.

les éléments qui viennent dtêtre décrits peuvent Astre fabriqués en matériaux divers tels que plastiques, métaux, etc.. et par les divers procédés convenables : moulage, extrusion, asseablage, etc.. leurs parois peuvent être traitées de toute façon appropriée en vue de favoriser ltécoulement du liquide. the elements which have just been described can be manufactured from various materials such as plastics, metals, etc. and by the various suitable methods: molding, extrusion, assembly, etc. their walls can be treated in any suitable manner in order to favor liquid flow.

Les circulations de liquide et de gaz peuvent etre parallè- les ou croisées. The liquid and gas flows can be parallel or crossed.

Dan9 l'exemple de réalisation des figures 6 et 7, pour lequel bien entendu on pourrait utiliser tout type d'éléments 1 convena- bles, lesdits éléments sont installés entre un bassin supérieur 8 et un bassin inférieur 10, radialement autour d'une cheminée 18 à tirage naturel. Dan9 the embodiment of Figures 6 and 7, for which of course one could use any type of suitable elements 1, said elements are installed between an upper basin 8 and a lower basin 10, radially around a chimney 18 natural draw.

Ces éléments sont par exemple du genre décrit en regard de la figure 1 mais, au lieu que leurs faces latérales 19 soient planes, elles sont ondulées dans le sens transversal à celui de l'écoulement de l'eau, ici le sens horizontal. Ces ondulations assurent acore un bon écoulement de l'eau en pellicules ou films uniformes L'air passe toujours aussi bien dans les canaux 5 que dans les intervalles 6 entre éléments. These elements are for example of the kind described with reference to FIG. 1 but, instead of their lateral faces 19 being flat, they are wavy in the direction transverse to that of the flow of the water, here the horizontal direction. These undulations ensure a good flow of water in uniform films or films. The air always passes as well through the channels 5 as into the intervals 6 between elements.

Naturellement, de tels éléments ondulés peuvent être utilisés dans tous autres types d'échangeurs. Naturally, such corrugated elements can be used in all other types of exchangers.

Il va tailleurs de soi que les modes de réalisation décrits ne sont que des exemples et que lton pourrait les modifier, notamment par substitution d'équivalents techniques, sans sortir pour cela du cadre de l'invention.  It goes without saying that the embodiments described are only examples and that lton could modify them, in particular by substitution of technical equivalents, without departing from the scope of the invention.
