Abstract

The lining for trickle irrigation is composed of at least two shaped segments, that is to say a flat segment A and a 3-D segment B joined in an assembly unit. The flat segment A of the lining is composed of longitudinally grooved flat elements, in which the longitudinal grooves are terminated by a transverse groove. Every element has a flat surface on the edges. The three-D element B is composed of left b and right b' elements which are alternately inserted, one having the appearance of a regular reflection of the other. Each three-D element is formed by a hypersurface situated above the orthogonal projection of the element, advantageously formed by the surface defined in a straight manner 4 and 4' in the form of a hyperbolic paraboloid, bounded on the two shortest opposite sides by oblique surfaces, advantageously by planes, and having in the opposite corners planes of contact with the neighbouring segments. The surface defined in a straight manner is advantageously grooved crosswise by two families of hyperbolic paraboloids.

The subject of the present invention is a trickling watering coating made of plastic material for heat exchangers without membranes, especially for countercurrent and forced draft refrigerants.

La demande de brevet d'invention polonaise n 69064 présente un garnissage pour échangeur-récupérateur renfermant des plaques profilées superposées formant des canaux de passage. chaque plaque étant-équipee d enco- ches doubles implantées en parallèle par rapport à elles et sortant symétriquement des deux côtés de la plaque. The Polish patent application No. 69064 has a lining for heat exchanger containing superimposed profiled plates forming passage channels. each plate being equipped with double notches implanted in parallel with respect to them and coming out symmetrically from both sides of the plate.

Les encoches doubles forment un angle aigu avec la direction du flux du liquide, les encoches de chaque plaque se croisent avec les encoches des plaques voisinés, et les plaques entrent en contact entre elles seulement aux points déterminés par l'intervalle entre les sommets des encoches.The double notches form an acute angle with the direction of the flow of the liquid, the notches of each plate intersect with the notches of adjacent plates, and the plates come into contact with each other only at the points determined by the interval between the notches of the notches .

L inconvénient de telles plaques réside dans la faible section hydrodynamique des canaux d écoulement d'air.  The disadvantage of such plates is the low hydrodynamic section of the air flow channels.

En plus. dans le cas de tels garnissages, l'échange de masse et de chaleur est peu important. More. in the case of such packings, the exchange of mass and heat is not important.

La présente invention a pour but d augmenter l'efficacité du processus d'échange de la masse et de la chaleur en élaborant un garnissage par arrosage ruisselant permettant une grande turbulence du flux d'air passant par le susdit garnissage et possédant une grande surface d'humidification par 1 eau du circuit de refroidissement et aussi une grande section hydraulique, provenant de l'espace entre les éléments. The object of the present invention is to increase the efficiency of the mass and heat exchange process by developing a trickling watering lining allowing a great turbulence of the flow of air passing through the aforesaid lining and having a large surface area. 1 water humidification of the cooling circuit and also a large hydraulic section, from the space between the elements.

Selon l'invention, le garnissage par arrosage ruisselant se compose au moins de deux segments façon nées. c' est-à-dire d'un segment plat et d'un segment spatial accouplés en un bloc de montage.  According to the invention, the trickling watering packing consists of at least two shaped segments. that is, a flat segment and a space segment coupled to a mounting block.

Le segment plat du garnissage se compose d ' élé- ments rainurés longitudinalement, dont les rainures longitudinales sont terminées par une rainure transversale, tout l'élément possédant une surface plate sur les rebords. The flat segment of the lining is composed of longitudinally grooved elements, the longitudinal grooves of which are terminated by a transverse groove, the whole element having a flat surface on the flanges.

Le segment spatial du garnissage se compose d'éléments gauches et droits implantés alternativement, dont l'un apparait comme réflexion régulière de l'autre
Chaque élément du segment est formé par I hypersurface située au-dessus de la projection orthogonale de 1'é1é- ment, formée avantageusement par la surface déterminée de façon droite sous forme de paraboloide hyperbolique, limitée sur les deux cotés les plus courts opposés par des surfaces obliques, avantageusement par des plans et possédant dans les coins opposés des plans de contact avec les segments voisins,
La surface déterminée de façon droite est avantageusement rainurée de façon transversale, notamment par deux familles de parabololdes hyperboliques dans le but d'obtenir une rigidité valable de l'ossature du garnissage et pour augmenter la surface d'humidification par l'eau.The space segment of the lining consists of alternately placed left and right elements, one of which appears as a regular reflection of the other.
Each element of the segment is formed by the hypersurface situated above the orthogonal projection of the element, advantageously formed by the surface determined in a straight manner in the form of a hyperbolic paraboloid, bounded on the two shortest sides opposed by oblique surfaces, advantageously by planes and having in the opposite corners planes of contact with the neighboring segments,
The surface determined in a straight manner is advantageously grooved transversely, in particular by two families of hyperbolic paraboloids in order to obtain a valid rigidity of the framework of the lining and to increase the humidification surface by water.

Selon l'invention, le garnissage par arrosage ruisselant peut etre facilement accouplé en blocs de dimensions modulaires quelconques, par exemple par collage ou par soudage par points. According to the invention, the trickling watering can be easily coupled into blocks of arbitrary modular dimensions, for example by gluing or by spot welding.

L'objet de l'invention est représenté sur le dessin sous forme d'exemple de réalisation, la figure 1 représentant le segment plat du garnissage par arrosage ruisselant et le segment spatial avec sa réflexion régulière en vue axonométrique, et la figure 2 représentant l'élément plat du segment plat et l'élément spatial du segment spatial, et sa réflexion régulière en vue axonométrique. The object of the invention is represented in the drawing in the form of an exemplary embodiment, FIG. 1 representing the flat segment of the trickling watering and the spatial segment with its regular reflection in axonometric view, and FIG. flat element of the flat segment and the spatial element of the spatial segment, and its regular reflection in axonometric view.

Le bloc de montage exemplaire du garnissage par arrosage ruisselant se compose de dix segments plats A, de cinq segments spatiaux B et de cinq segments spatiaux B' . apparaissant comme réflexion régulière des segments
B.The exemplary mounting block of the trickle watering pack consists of ten flat segments A, five spatial segments B and five spatial segments B '. appearing as regular reflection of the segments
B.

Les segments susdits sont collés en blocs de façon qu'entre chaque segment spatial B et B' soit implanté un segment plat A. The aforesaid segments are glued in blocks so that between each spatial segment B and B 'is implanted a flat segment A.

Le segment plat A du garnissage se compose de trois éléments a. Chaque élément a est équipé de huit rainures longitudinales 1, terminées des deux cotés par une rainure transversale 2. The flat segment A of the lining consists of three elements a. Each element a is equipped with eight longitudinal grooves 1, terminated on both sides by a transverse groove 2.
