Description
La présente invention concerne un appareil réfrigérateur à échangeur de chaleur plus particulièrement un réfrigérateur ou congélateur, présentant une plaque de support comportant un serpentin tubulaire disposé sur la surface de la plaque de support pour la circulation d'un fluide frigorigène. The present invention relates to a refrigerator apparatus with heat exchanger, more particularly a refrigerator or freezer, having a support plate comprising a tubular coil disposed on the surface of the support plate for the circulation of a refrigerant.
Il est généralement connu pour un appareil réfrigérateur d'utiliser en tant qu'évaporateur dans le circuit du fluide frigorigène un échangeur de chaleur comportant une plaque de support sur laquelle est fixé un serpentin tubulaire contenant le fluide frigorigène. It is generally known for a refrigerator appliance to use as an evaporator in the refrigerant circuit a heat exchanger comprising a support plate on which is fixed a tubular coil containing the refrigerant.
Une opération de travail est alors nécessaire pour fixer le serpentin sur la plaque pendant laquelle un outil doit être conduit sur toute la longueur-du serpentin tubulaire. Ainsi, un distributeur de colle, lors d'un collage, et un brûleur, lors d'une soudure, doivent être déplacés sur toute la longueur du serpentin tubulaire.A working operation is then necessary to fix the coil on the plate during which a tool must be driven over the entire length of the tubular coil. Thus, an adhesive distributor, during bonding, and a burner, during welding, must be moved over the entire length of the tubular coil.
L'invention a pour objet un mode de réalisation d'appareils réfrigérateurs,selon l'invention, permettant de fixer le serpentin tubulaire sur la plaque de support en utilisant des moyens techniques réduits. The subject of the invention is an embodiment of refrigerator apparatus, according to the invention, making it possible to fix the tubular coil on the support plate using reduced technical means.
L'objet de l'invention est réalisé par le faitqu'une feuille continue est étendue sur le serpentin tubulaire et sur la surface de la plaque de support délimitée par le serpentin tubulaire, feuille qui est reliée à la plaque de support à l'extérieur et entre les courbures du serpentin tubulaire et qui est tendue au-dessus du serpentin tubulaire. The object of the invention is achieved by the fact that a continuous sheet is extended on the tubular coil and on the surface of the support plate delimited by the tubular coil, which sheet is connected to the support plate on the outside. and between the curvatures of the tubular coil and which is stretched over the tubular coil.
Dans une forme de réalisation selon l'invention, la feuille est posée sur le serpentin, placé sur la plaque en formant des méandres, feuille qui recouvre toute la surface de la plaque de support délimitée par les méandres. Il suffit alors de fixer la feuille à la plaque au-delà du périmètre extérieur de celle-ci et entre les différents méandres. A cet effet, la feuille est réalisée de préférence en tant que feuille autocollante. Il suffit alors de la presser grâce à une presse élastique ce qui entraîne une tension de la feuille à la transition entre le dessus du serpentin tubulaire et la plaque de support. Ainsi, le serpentin tubulaire est bien maintenu sur la plaque et, du fait de la tension s'exerçant sur toute la longueur, le serpentin tubulaire est solidement appliqué contre la plaque de support. In one embodiment according to the invention, the sheet is placed on the coil, placed on the plate by forming meanders, a sheet which covers the entire surface of the support plate delimited by the meanders. It then suffices to fix the sheet to the plate beyond the outer perimeter thereof and between the various meanders. To this end, the sheet is preferably produced as an adhesive sheet. It then suffices to press it using an elastic press, which causes a tension of the sheet at the transition between the top of the tubular coil and the support plate. Thus, the tubular coil is well maintained on the plate and, due to the tension exerted over the entire length, the tubular coil is firmly applied against the support plate.
De préférence, la feuille est déformable à la chaleur (thermo-rétractable) de sorte qu'elle peut être aussi tendue par un procédé de thermo-retrécissement. Cependant, et dans une réalisation plus particulière, la plaque de support est disposée en face d'une deuxième paroi et l'espace entre ces deux parois est rempli d'une mousse de matière isolante-de la chaleur injectée chaude et sous pression. De ce fait, la feuille est pressée plus fortement dans la gorge creuse formée dans la zone située entre la surface d'appui du serpentin et la plaque de support. La tension qui est alors produite dans la feuille et qui s'exerce sur le serpentin tubulaire maintient celui-ci solidement sur la plaque de support.Preferably, the sheet is heat deformable (heat shrinkable) so that it can also be stretched by a heat shrink process. However, and in a more particular embodiment, the support plate is arranged in front of a second wall and the space between these two walls is filled with a foam of material insulating from the heat injected hot and under pressure. Therefore, the sheet is pressed more strongly in the hollow groove formed in the area between the support surface of the coil and the support plate. The tension which is then produced in the sheet and which is exerted on the tubular coil keeps it firmly on the support plate.
Diverses autres caractéristiques de l'invention ressortent d'ailleurs de la description détaillée qui suit. Various other characteristics of the invention will also emerge from the detailed description which follows.
Une forme de réalisation de l'objet de ltinvention est représentée,à titre d'exemple non limitatif, au dessin annexé. An embodiment of the object of the invention is shown, by way of nonlimiting example, in the accompanying drawing.
La fig. 1 est une vue d'un dispositif évaporateur présentant un serpentin tubulaire fixé par une feuille. Fig. 1 is a view of an evaporator device having a tubular coil fixed by a sheet.
La fig. 2 est une perspective partiellement arrachée d'une paroi d'un appareil réfrigérateur à fluide frigorigène. Fig. 2 is a perspective partially cut away from a wall of a refrigerator with refrigerant.
Un serpentin tubulaire 2 pré-sentant des courbures en forme de méandres repose sur une plaque de support 1 qui est réalisée en tant que boîtier pour être utilisée dans un compartiment de surgélation d'un appareil réfrigérateur et, en tant que plaque pour l'utilisation en tant qu'évaporateur frigori-fique,dans un compartiment frigorifique normal. Une feuille 3 est posée sur le serpentin tubulaire 2, feuille qui est collée sur la plaque de support 1 au-dessus du serpentin tubulaire 2. A tubular coil 2 having meandering curvatures rests on a support plate 1 which is produced as a housing for use in a freezer compartment of a refrigerator and, as a plate for use as a refrigeration evaporator, in a normal refrigeration compartment. A sheet 3 is placed on the tubular coil 2, a sheet which is glued to the support plate 1 above the tubular coil 2.
La feuille 3 réalisée en tant que feuille autocollante recouvre une surface qui couvre l'ensemble de toutes les courbures du serpentin tubulaire, feuille qui, endehors des méandres et aussi entre les méandres-est fixée à la plaque de support 1. Le collage s'effectue de telle manière que tout d'abord les parties des feuilles 3,les plus éloignées de la conduite tubulaire 2, soient appliquées sur la plaque de support 1 et qu'elle soit ensuite pressée vers le serpentin tubulaire. Etant donné que le serpentin est en saillie, la feuille 3 prend une position oblique à la transition entre la plaque de support et le serpentin tubulaire de sorte que la tension de la feuille augmente lorsque l'application de la pression progresse.Ainsi, le serpentin tubulaire est pressé sur toute sa longueur contre la plaque de support d'où il résulte une transmission optimale de la chaleur.The sheet 3 produced as a self-adhesive sheet covers a surface which covers all of the curvatures of the tubular coil, a sheet which, outside the meanders and also between the meanders - is fixed to the support plate 1. The bonding is performs in such a way that first of all the parts of the sheets 3, the most distant from the tubular pipe 2, are applied to the support plate 1 and that it is then pressed towards the tubular coil. Since the coil is protruding, the sheet 3 takes an oblique position at the transition between the support plate and the tubular coil so that the tension of the sheet increases as the application of pressure increases. tubular is pressed over its entire length against the support plate, resulting in optimal heat transmission.
Les extrémités de la feuille sont pliées autour des bords de plaque de support et fixées afin de bien maintenir la feuille sur la plaque de support. Ainsi, lorsque la pression est appliquée, la région voisine des extrémités de la feuille 3 ne peut pas glisser sur la plaque de support 1. La pression appliquée sur la feuille peut alors être effectuée, entre autres,par une presse élastique qui est d'abord appliquée sur les parties de la feuille 3 les plus éloignées du serpentin tubulaire, la feuille ne venant en application sur les côtés qugau moment ou elle subit une force de pression. The ends of the sheet are folded around the edges of the support plate and fixed in order to hold the sheet securely on the support plate. Thus, when the pressure is applied, the region close to the ends of the sheet 3 cannot slide on the support plate 1. The pressure applied to the sheet can then be carried out, inter alia, by an elastic press which is of first applied to the parts of the sheet 3 furthest from the tubular coil, the sheet coming into application on the sides only when it is subjected to a pressing force.
Cependant, il n'est pas nécessaire de tendre au maximum la feuille 3 ; une fixation provisoire est déjà suffisante si la plaque de support munie du serpentin tubulaire et la feuille sont placées en face d'une deuxième paroi dans l'appareil réfrigérateur et Si l'espace entre les deux parois est rempli en injectant une mousse de matière 4 isolante de la chaleur moussant sous l'effet de la pression et de la chaleur. Sous l'action de la pression et du dégagement de chaleur provoqués lorsque la mousse est injectée, la feuille 3 est fortement pressée par la matière isolante 4 vers le serpentin tubulaire 2 et plus particulièrement dans la gorge 5 délimitée par la plaque de support 1 et le serpentin tubulaire 2. Ainsi, la feuille est encore plus tendue et le serpentin tubulaire 2 e-st- pressé plus fortement contre laplaque de support 1.La pression d'application est aussi augmentée par la matière 4 isolante de la chaleur et exerçant-une pression sur le dos du serpentin tubulaire 2. A l'extérieur de la surface de contact avec le serpentin tubulaire 2 ou de la plaque de support 1, la feuille peut présenter au moins une ouverture pour éviter la formation de bulles d'air. En présence d'un petit nombre de telles ouvertures, la pénétration de la matière 4 isolante de la chaleur sous la feuille 3 est empêchée par la contre-pression exercée par l'air enfermé. Il est possible de prévoir une lumière correspondante dans la plaque de support 1. However, it is not necessary to stretch sheet 3 as much as possible; a temporary fixing is already sufficient if the support plate provided with the tubular coil and the sheet are placed opposite a second wall in the refrigerator appliance and If the space between the two walls is filled by injecting a foam of material 4 insulating from foaming heat under the effect of pressure and heat. Under the action of the pressure and the release of heat caused when the foam is injected, the sheet 3 is strongly pressed by the insulating material 4 towards the tubular coil 2 and more particularly in the groove 5 delimited by the support plate 1 and the tubular coil 2. Thus, the sheet is even tauter and the tubular coil 2 is pressed more strongly against the support plate 1. The application pressure is also increased by the material 4 insulating the heat and exerting- pressure on the back of the tubular coil 2. Outside the contact surface with the tubular coil 2 or the support plate 1, the sheet may have at least one opening to avoid the formation of air bubbles. In the presence of a small number of such openings, the penetration of the heat insulating material 4 under the sheet 3 is prevented by the back pressure exerted by the enclosed air. It is possible to provide a corresponding light in the support plate 1.
Lors de la fabrication d'un appareil réfrigérateur, il peut être procédé de telle manière que la feuille 3, réalisée de préférence en tant que feuille autocollante, soit posée sur la conduite tubulaire 1 qui repose ellemême sur la plaque de support 1. Cette plaque de support 1 peut alors être constituée par une paroi du boîtier intérieur ou de l'enveloppe extérieure, mais on peut aussi utiliser une plaque métallique de support qui est plus particulièrement collée sur la paroi de la cuve intérieure réalisée en matière plastique.En présence d'une cuve intérieure placée dans l'enveloppe extérieure de l'appareil réfrigérateur, l'espace entre la cuve intérieure et l'enveloppe extérieure recevant ltéchan- geur 1, 2, 3 est rempli par injection d'une mousse en matière - isolante de la chaleur après que le serpentin tubulaire 2 ait tété fixé par l'intermédiaire de la feuille 3 Du fait de la pression et de la chaleur provoquées pendant l'injection de la mousse, la feuille 3 est pressée, sur toute sa surface, contre le serpentin tubulaire 2 t la plaque de support 1 ; ainsi, le serpentin tubulaire 2 est solidement appliqué contre la plaque de support 7,
La feuille 3 peut être aussi appliquée fortement contre le serpentin tubulaire 2, et la plaque de support 1 Si elle est thermo-rétractable et donc soumise à un processus de chaleur-correspondant. En buut cas, une pression ultérieure appliquée à la feuille est obtenue par l'injection de mousse qui suit et par la pression exercée de ce fait sur toute la surface. During the manufacture of a refrigerator appliance, it can be done in such a way that the sheet 3, preferably made as a self-adhesive sheet, is placed on the tubular pipe 1 which itself rests on the support plate 1. This plate support 1 can then be constituted by a wall of the inner casing or of the outer casing, but it is also possible to use a metal support plate which is more particularly glued to the wall of the inner tank made of plastic. an inner tank placed in the outer casing of the refrigerator appliance, the space between the inner tank and the outer casing receiving the exchanger 1, 2, 3 is filled by injection of a foam material - insulating the heat after the tubular coil 2 has been sucked fixed by means of the sheet 3 Due to the pressure and the heat caused during the injection of the foam, the sheet 3 is pressed, all over e its surface, against the tubular coil 2 t the support plate 1; thus, the tubular coil 2 is firmly applied against the support plate 7,
The sheet 3 can also be applied strongly against the tubular coil 2, and the support plate 1 if it is heat-shrinkable and therefore subjected to a heat-corresponding process. In this case, a subsequent pressure applied to the sheet is obtained by the injection of foam which follows and by the pressure exerted thereby on the entire surface.
